Abstract

Strong AI is the view that the human mind is a computational device and computers are in principle capable of thought. In 1980, Searle published a paper which argued against this position by means of a thought experiment: the chinese room. In the years to come, many comments were made to this paper, of which we will discuss two. Central questions in this paper will be whether strong AI is true, and whether it is possible to create a true 'Artificial Intelligence'. All four views (strong AI, Searle, Harnad and Churchland) differ from one another, and all will be summarized and discussed.

In short, this paper discusses some important philosophical underpinnings of AI, by summarizing and discussing the views of three authors and strong AI itself.

Introduction

In 1980, Searle defined Strong AI, and argued against it by means of the Chinese Room Argument (CRA). Searle's argument was (and is) a direct challenge to proponents of Artificial Intelligence (AI), and the argument also has broad implications for functionalist and computational theories of meaning and of mind. As a result, there have been many critical replies to it.

In this paper we discuss two such replies (from Harnad and Churchland1), along with Searle's chinese room argument and of course strong AI itself. Central questions will be:

(1) is strong AI true?

(2) is strong AI possible, and how?

Note that this paper requires no prior knowledge of the philosophy of AI: all necessary terms will be explained. To begin with, we start with an explanation of Strong AI.

What is strong AI?

Strong AI is the view that the human mind is a computational device and computers are in principle capable of thought[1]. Supporters of strong AI believe that an appropriately programmed computer isn't simply a simulation or model of a mind, it actually would count as a mind. That is, it understands, has cognitive states, and can think.

The term was originally coined by John Searle, who writes:

"According to strong AI, the computer is not merely a tool in the study of the mind; rather, the appropriately programmed computer really is a mind"[2]

By contrast, 'weak AI' is the view that computers are merely useful in psychology, linguistics, and other areas, in part because they can simulate mental abilities. Weak AI makes no claim that computers actually understand or are intelligent.

Strong AI states that all there is to having a mind (having mental/cognitive states), is running a program (the right program of course). By program, we mean a sequence of steps, an algorithm. Programs executed on a computer are always purely symbolic (consisting only of symbols like letters or digits (0/1)). Because of that, computation is pure symbol manipulation (e.g. manipulation of the zero's and one's).

This leads us to computationalism, which states more or less the same as strong AI2. For reasons of simplicity, we use them interchangeably.

Computationalism is the theory that cognition is computation, that mental states are just computational states. According to Harnad [3], the following can be said of computationalism:

(1) Mental states are just implementations of (the right) computer program(s).

(Otherwise put: Mental states are just computational states).

(2) Computational states are implementation-independent. (Software is hardware-

independent).

1 When referring to Churchland, we actually refer to 'the churchlands', a a married couple, both professors of philosophy. Sometimes the singular form is more suitable in a sentence, sometimes the plural. In both cases, we refer to both of them, since they have written the paper[4] together.

2 For reasons of simplicity, we see strong AI, computationalism and functionalism as the same, and use them interchangeably.

The same holds for understanding, consciousness, intentionality, intelligence, and mentality (having a mind). When we say that a computer has intentionality, or that it can truly understand, we usually mean all these words.

If we combine (1) and (2) we get: Mental states are just implementation-

independent implementations of computer programs. This is not self-

contradictory. The computer program has to be physically implemented as a

dynamical system in order to become the corresponding computational state, but the physical details of the implementation are irrelevant to the computational

state that they implement -- except that there has to be some form of physical

implementation. Radically different physical systems can all be implementing one and the same computational system.

So basically, computationalism/strong AI states that running a program is enough for mentality, and that mentality is implementation-independent. This has some far-reaching implications:

- We now know how the mind works (including consciousness, etc), namely by just running a program

- Whether you run that program on a human or computer3, the result is the same (understanding, consciousness, etc).

- A computer can display any systematic pattern of responses to the environment whatsoever, and can have all mental states that humans have. It's just a matter of finding the right computer program (given enough time and storage space). Note that this is exactly what AI-researchers are doing: making intelligent programs.

- The programs that we make to simulate intelligence (e.g. Eliza, SAM, SHRDLU), are truly intelligent, and explain human intelligence

To make matters more concrete, let's consider such a program: SAM (Script Applier Mechanism), made by Roger Schank in 1977 [6]. Note that "nothing that follows depends upon the details of Schank's programs. The same arguments (coming after the story) would apply to Winograd's SHRDLU [7], Weizenbaum's ELIZA [8], and indeed any Turing machine simulation of human mental phenomena."[2]

Searle describes the program as follows[2]: (shortened)

"Very briefly, one can describe Schank's program as follows: the aim of the

program is to simulate the human ability to understand stories. It is characteristic of human beings' story-understanding capacity that they can answer questions

about the story even though the information that they give was never explicitly

stated in the story. Thus, for example, suppose you are given the following story:

A man went into a restaurant and ordered a hamburger. When the

hamburger arrived it was burned to a crisp, and the man stormed

out of the restaurant angrily, without paying for the hamburger

or leaving a tip.

Now, if you are asked 'Did the man eat the hamburger?', you will presumably

answer, 'No, he did not.' Schank's machines can similarly answer questions about restaurants in this fashion. "

According to Searle[2], partisans of strong AI claim that in this 'question and answer sequence', "the machine is not only simulating a human ability, but also that the machine can literally be said to understand the story and provide the answers to questions, and that what the machine and its program do explains the human ability to understand the story and answer questions about it."[2]

3 Note that a program can not only be run on a human or computer, but also on all sorts of crazy implementations like a roll of toilet paper, a pile of small stones, or a system of waterpipes and valves. To computationalism, all of these can have mentality, since they are all able to run a program. The question is just a matter of writing the right program, and enough time/spead and storage space.

Because of the huge size (10 billion neurons) and speed of the brain, these crazy implementations will not be suitable for reproducing the brain in real-time, but in principle they can.

These are exactly the claims that Searle likes to refute with his chinese room argument. But before going in to that, let's explore a bit more about computationalism.

According to Harnad[3], there's a third proposition about computationalism:

(3) There is no stronger empirical test for the presence of mental states than

Turing-Indistinguishability; hence the Turing Test is the decisive test for a

computationalist theory of mental states.

According to him, "this does not imply that passing the Turing Test (TT) is a guarantor of having a mind or that failing it is a guarantor of lacking one. It just means that we

cannot do any better than the TT, empirically speaking. Whatever cognition actually turns out to be -- whether just computation, or something more, or something else -- cognitive science can only ever be a form of 'reverse engineering' [10] and reverse-engineering has only two kinds of empirical data to go by: structure and function (the latter including all performance capacities). Because of tenet (2), computationalism has eschewed structure; that leaves only function. And the TT simply calls for functional equivalence (indeed, total functional indistinguishability) between the reverse-engineered candidate and the real thing."[3]

Now that we know what computationalism/strong AI is, we can ask two questions:

(1) is strong AI true? Are all claims made by strong AI true?

(2) is strong AI possible, and how? Can we really build an understanding computer, a

true 'Artificial Intelligence'? The holy grail of AI, a computer which can truly reason, solve problems, speaks fluently natural language, is intelligent and sapient (self-aware); is it possible? And if so, how?

Both questions will be addressed after the introduction, where we will discuss the views of computationalism and three writers (Searle, Harnad en Churchland).

About (1), we can already say that there's lots of discussion needed before we would have a final conclusion. We would have to discuss all objections to the CRA, and probably also understanding, consciousness, the symbol grounding problem, etc. It suffices to say that each of these topics has generated it's own pile of papers and books. In this paper we only discuss computationalism, and some of the arguments made by Searle, Harnad en Churchland.

About (2), we can already say that it can be answered in two ways, theoretically and practically. The theoretical approach will likely be (again) a long discussion, so let's take a look at the practical approach. Why don't we just skip the question, and start actually making the programs? And when we have a good enough program (e.g. which passes a test), we say, yes, this is strong AI!

Such an approach has indeed been taken. It's called the Turing test, and it tests the machine's capability to perform human-like conversation. If we cannot distinguish between a human and a machine in human-like conversation, the test concludes that the machine also has mentality.

This sounds like a great solution for believers of computationalism, because it ignores structure and only calls for functional equivalence (see tenet (3) above). Also, no introspectivism is needed (which suits cognitive scientists), and instead of long theoretical discussions, we can just start making programs (which suit pragmatists and

AI researchers).

Unfortunately, not everyone agrees. One of the objections phrased is that the machine only simulates mentality, while not actually understanding the conversation. This is one

of the things Searle intends to show with his chinese room argument: even if a program is indistinguishable from a human (it passes Turing test), it still understands nothing, and therefore, the Turing test is not a good enough test for understanding.

So alas, there's no simple way out for this one, we're condemned to dive into the theoretical discussion. As said, we will do this by summarizing and discussing the views of computationalism and three writers (Searle, Harnad en Churchland). Hopefully, some interesting conclusions will come out.

Views on Strong AI

We had 2 questions to answer:

(1) is strong AI true?

(2) is strong AI possible, and how?

Below we quickly summarize the viewpoints of computationalism, Searle, Harnad and Churchland, after which we will go more into depth into each of them.

To begin with, all disagree with one another on the first question. Computationalism of course agrees with itself. Searle does not, and lays out the chinese room argument to

'proof' computationalism is wrong. Harnad agrees with that proof, but points out the CRA is limited. The Churchlands disagree with Searle, and point to a fault in the CRA.

On the second question, all agree that strong AI is possible, but disagree on how to achieve it.

According to computationalism, having a mind is just a question of executing the right program, so we just have to write the right program (assuming it exists). Searle argues against this, by stating that even by executing the right program (a program which passes the Turing test), a computer will still understand nothing. According to him, a computer needs to have the same causal structures as a brain. Harnad and Churchland are also against computatationalism, but think hybrid or noncomputational systems (like artificial neural networks) will be the solution.

Computationalism:

Computationalism states that mentality is implementation-independent: whether you run a program on a human or computer, the result is the same (understanding, consciousness, etc). This is quite a big statement, and our intuition may think the opposite, so let's see what idea's lay behind it.

In his paper 'is the brain a digital computer'[11], Searle describes the 'primal story', which he describes as "a story about the relation of human intelligence to computation that goes back at least to Turing's classic paper[12]". He begins the primal story as follows: (slightly modified)

"We begin with two results in mathematical logic, the Church-Turing thesis and

Turing's theorem. For our purposes, the Church-Turing thesis states that for any

algorithm there is some Turing machine that can implement that algorithm (given enough time and storage space). Turing's theorem says that there is a Universal

Turing Machine which can simulate any Turing Machine. Now if we put these two

together, we have the result that a Universal Turing Machine (UTM) can

implement any algorithm whatever" [11].

Because the computer is a UTM, the computer can implement any algorithm. Now if computationalism is right, brains are Universal Turing Machines as well, and this would result in all far-reaching implications we described before.

Now, are there good reasons for supposing the brain might be a Universal Turing Machine?

"It is clear that at least some human mental abilities are algorithmic. For example,

I can consciously do long division by going through the steps of an algorithm for

solving long division problems. It is furthermore a consequence of the Church-

Turing thesis and Turing's theorem that anything a human can do algorithmically can be done on a Universal Turing Machine. I can implement, for example, the

very same algorithm that I use for long division on a digital computer. In such a

case, as described by Turing (l950), both I, the human computer, and the

mechanical computer are implementing the same algorithm, I am doing it

consciously, the mechanical computer nonconsciously.

Now it seems reasonable to suppose there might also be a whole lot of mental

processes going on in my brain nonconsciously which are also computational. And if so, we could find out how the brain works by simulating these very processes on

a digital computer. Just as we got a computer simulation of the processes for

doing long division, so we could get a computer simulation of the process for

understanding language, visual perception, categorization, etc." [11]

And so computatationalism concludes that all our brains processes are computational, and can therefore be simulated on a computer. Even more, this simulations are not just simulations, but the real thing; running the program is enough for mentality.

And so AI becomes a search for these programs, with results such as SAM, SHRDLU and ELIZA. And it is at this moment, that Searle comes in to say that those simulations are really just simulations, that we are not computers, and that syntax (symbol manipulation) is not enough for semantics.

Searle:

In 1980, Searle published a paper called 'Minds, brains, and programs' in which he defined strong AI (computationalism), and tries to prove it's wrong. He does this by laying out the chinese room argument, which shows that syntax is not enough for semantics, and therefore, that running a program cannot be sufficient for having a mind. According to him, for a computer to really understand natural language, it needs to have the same causal structures as the brain.

Below we will discuss these matters in more depth, beginning with a description of the chinese room argument.

According to Wikipedia, the Chinese room argument, goes as follows:

"Suppose that, many years from now, we have constructed a computer which

behaves as if it understands Chinese. In other words, the computer takes Chinese symbols as input, consults a large look-up table (as all computers can be

described as doing), and then produces other Chinese symbols as output.

Suppose that this computer performs this task so convincingly that it easily

passes the Turing test. In other words, it convinces a human Chinese speaker that it is a Chinese speaker. All the questions the human asks are responded to

appropriately, such that the Chinese speaker is convinced that he or she is talking to another Chinese speaker. The conclusion proponents of strong AI would like to draw is that the computer understands Chinese, just as the person does.

Now, Searle asks us to suppose that he is sitting inside the computer. In other

words, he is in a small room in which he receives Chinese symbols, looks them up on look-up table, and returns the Chinese symbols that are indicated by the table.

Searle notes, of course, that he doesn't understand a word of Chinese.

Furthermore, his lack of understanding goes to show, he argues, that computers

don't understand Chinese either, because they are in the same situation as he is.

They are mindless manipulators of symbols, just as he is - and they don't

understand what they're 'saying', just as he doesn't.

The conclusion of this argument is that running a program cannot create

understanding. The wider argument includes the claim that one cannot get

semantics (meaning) from syntax (formal symbol manipulation)." [13]

We might summarize this argument as a reductio ad absurdum against Strong AI:

"Let L be a natural language, and let us say that a 'program for L' is a program for conversing fluently in L. A computing system is any system, human or otherwise, that can run a program.

(1) If Strong AI is true, then there is a program for Chinese such that if any

computing system runs that program, that system thereby comes to understand

Chinese.

(2) I could run a program for Chinese without thereby coming to understand

Chinese.

(3) Therefore Strong AI is false.

The second premise is supported by the Chinese Room thought experiment."[13]

There've been lot's of objections raised against the chinese room argument. A summary of these can be found in the Stanford encyclopedia of philosophy [9]. For now it suffices to say that the fight is still going on:

"The many issues raised by the Chinese Room argument will not be settled until

there is a consensus about the nature of meaning, its relation to syntax, and

about the nature of consciousness. There continues to be significant disagreement about what processes create meaning, understanding, and consciousness, and

what can be proven a priori by thought experiments." [9]

So then Searle, if pure symbol manipulation cannot achieve strong AI, what can?

His view is that "only a machine could think, and indeed only very special kinds of machines, namely brains and machines that have the same causal powers as brains." Searle concludes to say, that "whatever else intentionality is, it is a biological phenomenon, and it is as likely to be as causally dependent on the specific biochemistry of its origins as lactation, photosynthesis, or any other biological phenomena." To keep things simple, one can take this as to mean that for a computer to actually think, it has to have the same biological structure as the brain. So basically, only biological brains can think, nothing else.

We will come back to this later, because Harnad and Churchland think there is actually a level between the two extremes (computationalism - only biological brains), namely hybrid or noncomputational systems.

Note that (apart from computationalism), the CRA also refutes the Turing test as a good enough test for understanding. Because according to Searle, even if a program passes it, it's still mindlessly manipulating symbols, and thereby understands nothing. The Turing test is a pure behavioural test (it only looks at the natural language behaviour of the system), while Searle is also interested in what's inside the system (brains or symbol

manipulation). The Turing test only looks at function, Searle also at structure (to be precise: the internal structure of the brain/computer).

If computationalism is true, we are allowed to only look at function (because the physical implementation doesn't matter), but because Searle 'proved' computationalism is false, we must also look at structure.

Harnad:

In his paper 'What's Wrong and Right About Searle's Chinese Room Argument?'[3], Harnad summarizes the chinese room argument, agrees with it (thereby refuting computationalism), and counters a few comments on the CRA. After that (with only one page left), he goes on to say that the CRA is limited to only refuting pure computationalism, and that "there are still plenty of degrees of freedom in both hybrid and noncomputational approaches".

He states that "for although the CRA shows that cognition cannot be all just computational, it certainly does not show that it cannot be computational at all".

Harnad concludes that Searle's contribution (the CRA) has not only been negative (destructing computationalism), but that "his critique has helped open up the vistas that are now called 'embodied cognition' and 'situated robotics'". Also, Harnad states that, thanks to Searle, he is now exploring neural nets.

The Churchlands:

According to the Churchlands, the CRA is false4, and so it's not proven that mentality cannot be achieved by pure symbol manipulation. However, due to performance failures of classical AI and specific characteristics of brains, they think that "classical AI is unlikely to yield conscious machines, but that "systems that mimic the brain might".

By classical AI, we refer to a movement at the beginning of the AI-research program, which has the goal of "identifying the undoubtedly complex function that governs the human pattern of response to the environment, and then write the program by which the Symbol Manipulation machine (SM-machine) will compute it."[4]. Note that by this description, classical AI is strongly dependant on claims made by

computationalism/strong AI.

By systems which mimic the brain, they refer to Artificial Neural Networks (ANN's).

Note that we have just answered the first major question (is strong AI true?), and are now tumbling into the second (is strong AI possible, and how?).

As said, the reasons that SM-machines may not lead to conscious intelligence, while

ANN's might, are twofold:

- performance failures of classical AI

- specific characteristics of brains (and thereby of ANN's as well)

By performance failures, they refer to the fact that SM-machines are not very good at object recognition. When compared to brains, computers were slower, and required vast knowledge bases, which of course created their own set of problems. The Churchlands conclude that "the functional architecture of classical SM machines is simply the wrong architecture for the very demanding jobs required". For these 'very demanding jobs', ANN's might be more suitable.

4 The arguments for this are a bit too long too state here. However, the Churchlands conclude that "even though Searle’s Chinese room may appear to be 'semantically dark', he is in no position to insist, on the strength of this appearance, that rule-governed symbol manipulation can never constitute semantic phenomena"

In general, we can make a distinction between brains and computers. Lot's of things can be said about their differences, the most important being:

- speed vs. parallelism: computers are roughly a million times faster than brains (both in signal propagation as in clock frequency), but brains have roughly 10^11 neurons (which can be seen as simple CPU's)

- symbol manipulation vs. vector manipulation. A computer does pure symbol manipulation (zero's and one's), while neural networks can be seen as vectors-transformers: input vectors are transformed by neurons and weighted links, after which they are outputted. According to the Churchlands, symbol manipulation appears to be just one of many cognitive skills that a network may or may not learn to display, but is certainly not it's basic mode of operation.

Note that by defining neural networks (and thereby ANN's) this way, this shields ANN's from Searle's chinese room argument. This is because Searle's argument is directed against rule-governed SM-machines, not against vector transformers.

But let us continue. Above, we made some distinctions between brains and computers. While these are interesting in itself, they result in the fact that brains and computers are useful for radically different types of computational problems.

"Parallel processing is not ideal for all types of computation. On tasks that require only a small input vector, but many millions of swiftly iterated recursive

computations, the brain performs very badly, whereas classical SM machines

excel. This class of computations is very large and important, so classical

machines will always be useful, indeed, vital.

There is, however, an equally large class of computations for which the brain’s

architecture is the superior technology. These are the computations that typically confront living creatures: recognizing a predator’s outline in a noisy environment;

recalling instantly how to avoid its gaze, flee its approach or fend off its attack;

distinguishing food from nonfood; and so on"[4]

With this knowledge in mind, we can answer the question: 'is strong AI possible, and how?'. To the Churchlands, the answer is that "pure SM-machines are unlikely to yield conscious intelligence, but that systems that mimic the brain might". They conclude to say that "only research can decide how closely an artificial system must mimic the biological one, to be capable of intelligence."

Conclusion

We've seen statements of strong AI/computationalism, and three views commenting on that. All tried to answer 2 questions:

(1) is strong AI true?

(2) is strong AI possible, and how?

Computationalism of course agrees that strong AI is true, and states that running a program is enough for creating a strong Artifical Intelligence. Searle argued against this (by stating the CRA), and concluded that computationalism is false. To him, strong AI can only be achieved by a computer having the same causal relations as the brain. Harnad agrees with that, but points out the CRA is limited to refuting only pure computationalism, which leaves "still plenty of degrees of freedom in both hybrid and noncomputational approaches". The Churchlands argue the chinese room argument is false, and so it's not proven that mentality cannot be achieved by pure symbol manipulation. However, due to performance failures of classical AI and specific characteristics of brains, they think that "classical AI is unlikely to yield conscious machines, but that systems that mimic the brain might".

While computationalism and Searle both have clear statements on what is needed and sufficient for achieving a strong AI, Harnad and Churchland leave the question open for empirical research to decide.

Finally, because there's disagreement over what is needed for mentality, there's also disagreement over whether the Turing test is a good enough test for mentality. Computationalism clearly states yes; Searle clearly states no; Harnad and the Churchlands are somewhere in between (for reasons unstated in this paper).

This paper was about strong AI/computationalism, the chinese room argument, the Turing test, understanding, consciousness, the relation between syntax and semantics, etc. For each of these terrains, there are loads of problems, loads of papers, and no consensus. This paper has only given an overview on some of these.

More research, especially in the domains of cognitive science and artificial intelligence, will hopefully shed some light one these issues.

毛文超:这是我经常被问到一个问题,到底社区该怎么玩,或者到底一个社区是怎么做起来的。现在为止,我们小红书福利社社区的用户分成几种人,有的是分享他们到国外买好东西的经验,有的去国外旅游之前会来逛逛然后做心愿单,有的是在国内也会分享海淘经验。当然,更多的人是在社区里面互动,包括点赞、评论,以及分享他们喜欢的内容到朋友圈。我觉得每个社区最后能够走到多远,或者它能创造什么价值,最重要的是两件事:第一个是它的种子用户是谁,这个奠定了社区的基因;第二件事是核心规则,作为一个社区管理者,我们小红书福利社鼓励什么样的行为,不鼓励什么样的行为,这个决定了社区能走多远。 我们小红书福利社最早一批的核心用户,在我看来,是85后、90后这样一代对生活品质有要求的意见领袖。因为我们最早提供的是一个海外购物攻略。相信在座很多人都会出国旅游,而购物肯定是必不可少的环节,这个是整个中国的大环境。事实上,你们都是这方面的意见领袖。所以我们小红书很快积累了这样一批用户,并开始发酵。 我们在玩法上比较鼓励去中心化的方式,每个人都能发挥自己的意见,这个事情对小红书福利社活跃度贡献很大,每个人都有机会把好内容带给大家,而不是说我是台下用户,等着台上几个人给我灌输观点。小红书这种纯UGC的形式非常符合口碑营销时代的需求,也是小红书福利社社区能一直保持高活跃度,高信任度,最终也代表了高转化率的重要原因。 如何从社区升级为社区型电商? 牛千:我上小红书就想买一个什么东西,我就想直接看到这个东西多少钱,在哪里可以买到,像我这样的用户,我不太喜欢在小红书福利社社区里面去逛,你们有没有这方面的计划,把社区用户分享的很好的内容把它更好的结构化,把它带给更多的普通用户? 毛文超:女性用户分为两类,特别爱购物的,和比较爱购物的。对于后者,用户特点是既有发现的需求,却没有太多的时间闲逛,需要快速找到自己喜欢的东西,这其实占用户的主流。对于这类用户,我们就需要尽可能的去懂她,知道她是谁,可能会喜欢什么,也就是“个性化”。我们小红书从去年8月份开始,已经开始默默的通过标签结构化社区里的所有UGC内容,我们小红书福利社社区里面现在有40多万的标签,这是我们为沉淀下来的几百万条真实用户分享的海外商品口碑贴上的索引。同时我们也记录和储存了用户所有的使用行为,比如喜欢一个笔记,加入一个心愿单,点击了哪条笔记,关注了哪个用户和哪类标签等等。小红书接下来的战略重点就是通过这些数据让用户发现的效率更高。 小红书的盈利模式是什么?

员工福利

《员工福利管理》 一、辨析题练习题 1.二战以来,福利国家危机的出现以及国家在社会保障方面支出的减少是员工福利飞速发展的原因。 2.按照员工享受福利的条件有无和种类,员工福利计划模式可以划分为统一型和差异型两种模式。 3.在我国,法定福利包括社会保险、法定假期和企业补充保险。 4.在企业年金的投资中,收益性原则是最重要的投资原则。 5.在我国,住房公积金由企业单方缴费,员工个人不需要缴费。 6.从企业的角度考虑,企业的薪酬策略也会影响员工福利设置,企业的薪酬策略就是企业的薪酬水平策略。 简答题参考要点: 1. 二战以来,福利国家危机的出现以及国家在社会保障方面支出的减少是员工福利飞速发展的原因。 解答: 错。 二战以来,员工福利的高速发展是多种因素共同作用的结果: 1.社会政治经济环境为员工福利提供了发展的空间; 2.雇主对员工福利作用的深刻认识,引导企业从被动接受福利要求到主动提供福利计划; 3.政府介入员工福利领域,通过立法规范、政策支持、税收优惠等手段,促进了员工福利; 4.雇员对福利的认可接受程度也一定程度利于福利发展; 5.工会对员工福利的推动作用; 6.信息技术及管理技术的进步促进了员工福利的发展。 2. 按照员工享受福利的条件有无和种类,员工福利计划模式可以划分为统一型和差异型两种模式。 解答: 错。 按照员工享受福利的条件有无和种类,员工福利计划模式可以划分为免费型、绩效型和资历型三种。(一)免费型模式。免费型模式是指不论员工的工作绩效如何或员工现在是否在岗(或者退休),只要是企业的正式员工,都可以无条件获得企业设置的福利计划。(二)绩效型模式。绩效型模式是指员工要想获得一定的福利水平或者福利项目,必须达到一定的工作绩效标准。绩效型模式将福利的有无、福利的晋升与员工的工作绩效评价结果有机的结合起来,大大地增加了福利的激励作用。(三)资历型模式。资历型模式是以员工在企业里的工作时间为福利享受或晋升标准。主要适用于那些强调终身雇佣的企业,也适用于企业想挽留的核心员工。 按照企业给员工提供的福利项目对象的一致性不同,员工福利计划可以划分为统一型和差异型两种模式。(一)统一型模式。统一型模式也叫全员型模式,指企业向员工提供的福利在内容上是一致的,即所有的员工享受到的福利项目都是一样的。(二)差异型模式。差异型模式是指企业向员工提供不同内容的福利,以满足员工不同的需求。在实践中,差异型模式的实施可以有不同的方式,弹性福利计划就是其中最有代表性的一种。 3. 在我国,法定福利包括社会保险、法定假期和企业补充保险。

那些年我们享受过的美国福利

那些年我们享受过的美国福利 前几天吃晚饭时,妻子告诉我她买菜的经历:到了超市收银台准备付款,前面一个十几岁的母亲抱着个孩子,拿出一叠儿童食物券WIC,全名叫“妇女、婴儿、儿童特别营养补助券”(Special Supplemental Nutrition Program for Women, Infants and Children);收银员没有见过,不知道怎么处理,赶紧呼叫经理,闹得大家都得等。那女孩子特别难为情,转身一个劲儿地说:“对不起!对不起!”妻子本想安慰她一下,告诉她自己当年也用过这个。但话还没有出口,收银员已经搞明白怎么处理、招呼那位女孩儿。她也赶集抱着孩子去付款了。 这一段小插曲,勾起了我们十多年前的往事。我们当时住在无家可归者遍地的纽黑文,超市里许多顾客都使用各种食物券。收银员有专门的训练,处理得很熟练。如今,我们住在波士顿富裕的郊区。这里看不到无家可归者,超市里也难得见到有食物券的。怪不得收银员一时抓瞎。偶然碰上这样的场面,仿佛自己一下子回到了那个其乐无穷的苦日子,并像昨天一样历历在目,同时也惊叹我们的生活会发生了如此之大的变化。 无巧不成书,妻子讲述这些事情时,我发了一段有关的微博: “我奇怪中国的孩子看病为什么要交钱。有网友质问:哪国不交钱?我告他:没文化真可怕。孩子在美出生时我们是一贫如洗的两个外国人。孩子医保一直到22岁,去医院政府派车,相当‘豪华’,还给一大堆食物券保证营养。孩子吃 不了,父母就跟着‘蹭吃喝’。美国这方面还是发达国家中最差的。” 这里有另外一条缘由。这条微博本是对另一条微博的跟帖:一位母亲借来五千块抱着幼子去医院看病,结果钱全被偷光,绝望之下嚎啕大哭。据说医护人员仍然安排治疗,让人欣慰。但那微博配有照片,看了心情很沉重,我就随手写了这么一条。后来觉得应强调一下儿童看病应该免费的立场,干脆扶正单发了。没想到,这么几个字居然有爆炸性的效果。几个小时内,阅读量超过170万,评论过千,转发过三千。那一千多条跟帖,绝大部分是谩骂,有说我造谣骗人的,有说我伪造收入蹭福利并要举报的,更有说“丢人丢到国外”去的。还有些帖子,居然在那里质疑:这么穷怎么还能出国?仿佛只有贪官才配出国。 这一千多的跟帖,多少帮助我了解了中国的世相。这种世相,又多多少少建构在对美国的种种误解之上。所以,我不妨从亲身经历开始,讲述一下一对“一贫如洗”的夫妻在美国生了孩子后的经历。 首先讲讲我们为什么“一贫如洗”。在这一千多跟帖中,反复出现的质问是:“一贫如洗怎么能出国?”即使我这个一天到晚上网,自认为还算了解中国的人,读到这样的问题也感到吃惊,接着马上就意识到:时代的变化是多么巨大! 在我们留学的那个年月,即从七十年代末到九十年代初,出国的主力都是“一贫如洗”的。他们大多是从美国的大学拿了全奖,有的借钱买张机票,就这

福利的概念: 在参考借鉴国内外学者对于福利的定义和实践理解的基础上,中国人民大学劳动人事学院文跃然副教授认为应该从以下几个方面来把握福利的概念: (1)员工福利是总体报酬的重要组成部分; (2)员工福利大多表现为非现金收入; (3)员工福利通常采取非直接的支付方式。 福利的功能 首先,良好的福利制度可以帮助实现企业人力资源管理活动的目标,进而实现企业的战略目标。良好的福利制度不但可以吸引和保留所需要的员工,而且有助于充分发挥员工的极性和主动性。支持性的工作环境是影响员工工作满意度的重要因素,员工福利由于其特点会对工作环境产生积极的影响,从而提高员工对工作的满意度。虽然目前没有充分的研究能够证明员工福利会对绩效产生直接的积极影响,不过我们仍有理由相信员工福利可以通过满意度这一中间变量对工作绩效产生影响。此外,福利有利于节省企业的人工成本。一方面员工福利具有避税功能,另一方面在战略转型过程中企业可以通过改变福利政策促进人才的退出和补给,因此良好的福利制度是一种帮助企业战略落地的重要工具。 其次,设计良好的福利制度可以鼓励员工之间的合作。收益分享计划是 一种管理系统、管理哲学和管理文化,其三个要点是参与、团队、和分享。收益分享计划的重要理念就是团队合作。其实团队的绩效不是优异表现者创造出来的,而是团队合作创造出来的。福利跟奖金不一样,奖金更多的是计算,福利的分配更加倾向于平均化,更加适合做团队的报酬形式。从这个意义上来说,福利鼓励团队合作。 第三,员工福利是影响企业劳动力雇用决策的重要因素。如果员工福 利在企业的人工成本占的比重过大,那么企业可能会考虑通过雇佣临时工代替正式员工来节省福利的开支。《劳动合同法》实施以后,企业雇佣员工更加谨慎,福利也是值得考虑的一个重要方面。 第四,福利能够传递企业的文化和价值观。企业文化和价值观在福利上 都会得到体现。福利是体现企业的管理特色、传递企业对员工的关怀、创造一个大家庭式的工作氛围和组织环境的重要手段。员工对企业文化和价值观的认同是企业战略落实的先决条件之一。亚里士多德说过“优秀是一种习惯”,洛克菲勒在谈到习惯与企业经营的关系时认为应该用价值观去管理员工。但是在管理中,管理员工的结果不如管理员工的行为,管理行为不如管理习惯。在很大程度上,

福利经济学期末复习资料知识分享

福利经济学期末复习 资料

福利经济学复习资料 名词解释 福利:指个人生活的幸福或快乐程度,不仅指物质生活的满足,也指精神生活的满足。 福利经济学:是20世纪初逐步发展起来的一门理论和应用经济科学,它以研究社会经济发展与社会福利改善的关系为宗旨,是众多学科交叉和多方面学术观点汇聚的一门社会科学。 基数效用:是指可以用基数即实数来度量的效用概念。(基数效用论者认为,效用可以具体衡量并加总求和,具体的效用量之间的比较是有意义的。) 序数效用:是指不能用基数度量而只能排序的效用概念。(序数效用论者认为,效用的大小是无法具体衡量的,效用之间的比较只能通过顺序或等级来表示。) 帕累托改进:是指这样一种状态,即一项社会变革使得一部分人的社会福利增加的同时,并不减少其他社会成员的福利。 帕累托最优:是指资源配置达到这样一种社会经济状态,即不论实行何种社会经济政策变动,在使一部分人的福利水平上升的同时,必然使另一部分人的福利水平下降。 福利经济学第一定理:完全竞争市场的一般均衡状态就是帕累托最优状态。 福利经济学第二定理:从任一个初始资源配置状态出发,通过市场竞争机制形成的均衡必然可以实现帕累托最优状态。 卡尔多-希克斯补偿标准: 卡尔多补偿标准:如果受益者能完全补偿受损者之后还有剩余,则整体社会福利有所改善。

希克斯补偿标准:如果受损者不能通过收入重组来补偿受益者以阻止改革发生,那么该项改革就是可取的。 李特尔补偿标准:如果某项改革同时满足卡尔多补偿标准以及希克斯补偿标准,并且使收入分配更合理的话,那么该项社会改革就是可取的。 补偿剩余(CS):是指当价格发生变动之后,若保持消费者在价格变动之前的效用水平,并且限制消费者在新的价格下购买没有补偿效用时所愿意购买的数量,在这种情况下应从消费者提取或者给予的货币量。 补偿变差(CV):是指当价格发生变动之后,若保持消费者在价格变动之前的效用水平时所需要给予消费者或从消费者手里取走的货币量。 等同剩余(ES):是指在现行价格基础上,如果限定消费者购买价格变动之前的购买量,要达到价格变动之后的效用水平所需要给予或取走的货币量。 等同变差(EV):是指在现行价格下,要使消费者达到价格变动之后的效用水平,所必须给予或者取走的货币量。 市场失灵:由于内在功能性缺陷和外部条件缺陷引起的,市场机制在资源配置的某些领域运作不灵,即只靠市场达不到资源最优配置。 道德风险:市场交易中的一份无法观察到另一方所控制和采取行动时所发生的知情方故意不采取谨慎行为的情形。 逆向选择:市场交易中一方无法观察到另一方的重要外生特征时所发生的劣质品驱逐优质品的情形,是事前的信息不对称。 科斯定理:无论初始产权如何界定,只要交易费用足够小,效率结果相同,市场就可解决外部性问题。
