The principal difficulty: Besley’s neo-Rousseavian aspirations

The use of the “principal–agent” model makes an implicit assumption about the existence of an underlying global optimum or “general will.” This assumption is debatable, and Besley does not defend it sufficiently or even seem to realize how strong an assumption it is. Still, it is standard in the literature, and Besley’s book is a very strong contribution to that literature. Its two greatest strengths are its solid microfoundations, and its use of the classical “comparative statics” approach to analyze dynamics.      

COMPARATIVE STATICS OF A MONOPOLISTIC FIRM FACING RATE‐OF‐RETURN AND COMMAND‐AND‐CONTROL POLLUTION CONSTRAINTS

The intrinsic comparative statics properties of a general rate‐of‐return regulated, profit‐maximizing model of a monopolist facing a command‐and‐control pollution constraint are derived. Recent advances in the theory of comparative statics are used to derive the basic comparative statics of the model, which are contained in an observable negative semi‐definite matrix and possess the form of Slutsky‐like expressions. We consider several command‐and‐control pollution constraints that are commonly implemented in practice, and conclude that the intrinsic comparative statics properties of the model are qualitatively invariant to the type of command‐and‐control pollution constraint imposed. We compare our results with those extant, and find that several basic results from the standard A–J model no longer hold in our model.     

Stackelberg leadership with product differentiation and endogenous entry: some comparative static and limiting results

Allowing for endogenous entry in the traditional Stackelberg setup with product differentiation, leads to reverting of the standard comparative static and limiting results. Unlike in the standard Stackelberg setup with barriers to entry, the leader??s profit increases when the differentiation becomes lower. The reason is that competition becomes tougher when products become more alike, and consequently, fewer firms enter in equilibrium. On the other hand, increasing product differentiation towards its limit results in number of entrants tending to infinity and for very large market, the profit of the leader approaches zero. Thus market structure approaches monopolistic competition, rather than the standard monopoly outcome that occurs with exogenous number of followers.     

Some Reflections on The Calculus of Consent

Buchanan and Tullock claim in The Calculus of Consent that their analysis does not depend for its validity on the assumption of homo economicus. Some thirty years later Brennan and Buchanan argued that homo economicus is the relevant assumption for institutional design. If the prime task of comparative institutional analysis is conceived to be how the views and interests held by one individual can be reconciled with the views and interests of others, then either altruistic or self-centred behavior can be relevant to the analysis depending on the case at hand. Buchanan and Tullock's claim is therefore not without some justification.     

Environmental policy and lobbying in small open economies

This paper analyzes consequences of lobby group activity for policy outcomes in economies with transboundary pollution and international environmental policies. International environmental policies are here characterized as pollution taxes determined in a negotiation between two countries. The optimal pollution taxes are characterized and comparative statics are carried out to increase the understanding of mechanisms underlying pollution taxes in the specified setup. It is found, among other things, that the presence of local lobbying may decrease, as well as increase pollution taxes - depending on, e.g. an assumption of symmetry.     

A Neo-Heckscher–Ohlin Model of Trade with Endogenous Production Patterns*

We propose a Neo-Heckscher–Ohlin (HO) model of trade that combines comparative endowment advantage, comparative technological advantage, international capital mobility and trade costs. Using an inframarginal approach, we produce a partition of the exogenous parameter space in a host of parameter value subsets that demarcate the various equilibrium patterns of production and trade. The results are startling! They suggest that production within the diversification cone – a key assumption of the Heckscher–Ohlin theory that is required for its core propositions (such as factor price equalisation) to hold – may only prevail on the razor's edge, or under exceptional circumstances. In addition, our findings nominate a mechanism by which improvements in transaction efficiency facilitate international trade thereby stimulating cross-country division of labour. Contrary to other generalisations of the Heckscher–Ohlin (such as the various derivatives of the Kemp–Jones model of trade), our model does not assume a purely Ricardian character: comparative endowment advantage may determine the pattern of trade even in the presence of opposing technological differences, as long as total factor productivity coefficients adjusted for transaction efficiency and factor intensity do not confer unambiguous comparative (technological) advantage. Still, ‘intensity-efficiency’-adjusted comparative technological advantage supersedes factor endowments in determining the flow of trade.     

Distorted Trade Barriers: A Dissection of Trade Costs in a “Distorted Gravity” Model

It is common in the trade literature to use iceberg transport costs to represent both tariffs and shipping costs alike. However, in models with monopolistic competition these are not identical trade restrictions. This difference is driven by how the two costs affect the extensive margin. We illustrate these differences in a gravity model. We show theoretically that trade flows are more elastic with respect to tariffs than transport costs and find a linear relationship between the elasticities with respect to tariffs, iceberg transport costs, and fixed market costs. We empirically validate these results using data on US product‐level imports.     

Imprecise probabilistic beliefs as a context for decision-making under ambiguity

Coherent imprecise probabilistic beliefs are modeled as incomplete comparative likelihood relations admitting a multiple-prior representation. Under a structural assumption of Equidivisibility, we provide an axiomatization of such relations and show uniqueness of the representation. In the second part of the paper, we formulate a behaviorally general “Likelihood Compatibility” axiom relating preferences and probabilistic beliefs and characterize its implications for the class of “invariant biseparable” preferences that includes the MEU and CEU models among others.     

自生能力、经济转型与新古典经济学的反思

现有的新古典经济学理论体系把企业具有自生能力作为暗含的前提。但是 ,转型中国家和其他许多发展中国家的企业却因政府的赶超愿望 ,进入不具比较优势的产业而不具自生能力。当经济中大量企业缺乏自生能力时 ,实行根据新古典经济学所制定的改革或转型政策 ,往往达不到预期效果 ,而且 ,可能给社会带来巨大痛苦。本文主张 ,在分析社会主义经济、转型经济和发展经济问题时 ,放弃现有的新古典经济学体系中企业具有自生能力的暗含前提 ,把企业是否具有自生能力作为一个具体的考虑变量 ,这是新古典经济学理论的必要发展。     

Secret information acquisition in Cournot markets

Summary. Two-stage game models of information acquisition in stochastic oligopolies require the assumption that firms observe the precision of information chosen by their competitors before determining quantities. This paper analyzes secret information acquisition as a one-stage game. Relative to the two-stage game firms are shown to acquire less information. Policy implications based on the two-stage game yield, therefore, too high taxes or too low subsidies for research activities. For the case of heterogeneous duopoly we briefly discuss comparative statics results. Received: August 9, 1999; revised version: May 31, 2000     

FOREIGN DIRECT INVESTMENT,NON‐TRADED GOODS AND REAL WAGES

Using a three‐sector general equilibrium model with non‐traded goods, we investigate the impact of foreign direct investment on the real wages of skilled and unskilled workers. We show that foreign direct investment increases the real wages of skilled and unskilled workers alike, but widens the gap between the two under plausible conditions.     

A Complete Characterization of Efficient Liability Rules: Comment

In a recent article, Jain and Singh (2002) prove that a condition they call negligence liability is necessary and sufficient for any liability rule to be efficient. In this note I criticize their result on two accounts: First, their result crucially depends on implicit restrictions they impose on the liability assignment function. If we drop the assumption that the liability apportionment between two non-negligent parties is constant for all combinations of non-negligent care levels, the equivalence between the condition of negligence liability and the efficiency of liability rules breaks down. Second, their attempt to drop the assumption of uniqueness for the social optimum improves the generality of the model at a substantial cost, since it must be accompanied by a new assumption that is possibly even more unrealistic. The importance of the uniqueness assumption is shown in a simple discrete care model, in which comparative negligence may lead to an inefficient outcome when the existence of two social optima leads us to interpret due care as a varying standard based on the other partys actual choice.     

对公司股东与利益相关者的比较研究--一个契约理论的扩展分析

主流的企业契约或契约连接点理论对解释现代公司提供了一个具有说服力的规范性理由,尤其在与股东的关系方面.但契约理论本身并没有具体要求其研究的主体必须是股东还是利益相关者.更有甚者,该理论允许任何处于契约连接点的各方通过相互同意所达成的经济组织方式.本文通过对该理论的一个简单扩展,对股东和利益相关者作了进一步的比较,其结论可以缓解我们对这二者之间对立性的认识,并对现实的公司具体的激励机制设计有所帮助.     

ON NON‐MONETARY MEASURES IN THE FACE OF RISKS AND THE SIGNS OF THE DERIVATIVES

Vulnerability of both prudence and temperance towards a sure loss and towards a zero‐mean background risk seems to be a very realistic assumption on individual preference. This paper shows that when the concepts of prudence and temperance are defined in non‐monetary terms, the above assumption is equivalent to the usual signs of the successive derivatives of the utility function.     

Do environmental regulations influence the competitiveness of pollution-intensive products?

According to “Pollution Haven Effect”, in order to circumvent stringent environment standards, polluting industries in developed countries will be chosen to locate into developing countries; another way is that developed countries increase imports of pollution-intensive products instead of producing by their own, both of which can contribute to the changes of comparative advantages in the past 30 years. Since 1990s, many scholars have paid special attention on whether environmental regulations affect the trade patterns or not, but the conclusions are ambiguous. This paper, based on the Heckscher-Ohlin-Vanek (HOV) model and using 95 and 42 countries sample data in year of 2005, is an empirical analysis which shows that: (1) according to the estimated results based on the “environmental governance” index calculated by CIESIN, environmental regulations do not change the comparative advantages of five types of pollutionintensive goods; (2) On the other hand, when the per capita income is considered as an endogenous indicator of environmental regulation, environmental regulation will significantly promote the comparative advantages in chemical products, iron and steel products and paper products, though environmental regulations do not take any influence on non-metallic minerals products and non-ferrous metals products. I think that appropriate level of environmental regulation can promote a comparative advantage in pollution-intensive goods.     

Trade policy and distortions in intra-Asian trade

This paper analysis wheather the level of tariffs and non-tariff barriers affect the pattern of inter-industry trade within Asia. The Heckscher–Ohlin theorem is based on the assumption of efficient resource allocation. However, markets in many developing countries protect the domestic production by trade barriers. We would therefore expect the pattern of production and trade not to reflect comparative advantages perfectly. It is found that import charges and non-tariff barriers have a significant positive impact on capital intensities in net export.     

A Test for Parameter Homogeneity in CO<Subscript>2</Subscript>Panel EKC Estimations

This paper casts doubt on empirical results based on panel estimations of an “inverted-U” relationship between per capita GDP and pollution. Using a new dataset for OECD countries on carbon dioxide emissions for the period 1960–1997, we find that the crucial assumption of homogeneity across countries is problematic. Decisively rejected are model specifications that feature even weaker homogeneity assumptions than are commonly used. Furthermore, our results challenge the existence of an overall Environmental Kuznets Curve for carbon dioxide emissions.     

COMPARATIVE EFFICIENCY BETWEEN COOPERATIVE,SAVINGS AND COMMERCIAL BANKS IN EUROPE USING THE FRONTIER APPROACH

We test competing hypotheses concerning the comparative behavior of shareholder‐owned commercial banks and stakeholder‐orientated cooperative and savings banks in European banking. One hypothesis is that the risk culture and business models of stakeholder and shareholder‐owned banks have become more alike and so cost efficiency has converged between bank ownership structures. The alternative hypothesis suggests that institutional differences do matter and lead, amongst other things, to variation in network effects and monitoring mechanisms producing differing behaviors and efficiency outcomes. By using a novel panel data set of 521 European banks during 1994–2010, we find: (i) mean inefficiency scores vary by ownership type and are lower for cooperative banks than for commercial and savings banks; (ii) there is a large variation in inefficiency scores among banks within each ownership type but the lower variance for cooperative banks indicates that they are the most homogeneous group; (iii) the inefficiency distribution of savings and commercial banks appear to arise from the same distribution, but this does not hold for cooperative banks. As such our findings are more consistent with the alternative hypothesis. Our first two findings buttress those studies that found significant differences between European banks with differing ownership structures, while our third finding on the significance of the cycle to the distribution of inefficiency is novel.     

On the Endogeneity of Market Power in Emissions Markets

Previous approaches on market power in emissions trading markets rely on the existence of a subset of competitive players. In this paper, I relax this assumption and treat market power as an endogenous concept which depends on the initial allocation of allowances. All parties realize their potential influence on the market price. This approach allows a clear comparative statics analysis of the impact of the allowance allocation on the efficiency of markets. I provide specific examples that illustrate the implications that stem from the proposed modeling approach relative to previous models.     

R&D and manufacturing production specialization in developed economies

A study of the relation between technology and manufacturing production specialization in a series of developed economies is performed by means of models relating indicators of revealed symmetric comparative advantage of value added and exports to similar measures of comparative performance of R&D expenditure, capital intensity, total factor productivity and wage costs. The production and R&D specialization are shown to be substantial and sticky. This contrasts with the evidence of a substantial degree of convergence in the patterns of the other variables. Regression estimates show that, although all variables play their part, the impact of comparative R&D efforts on production specialization is by far the strongest. This impact is found to be stronger in the smaller economies and it is especially important in research-intensive industries. The influence of comparative wages is, moreover, found to be positive here, suggesting the dominance of a labour skill and efficiency wage effect over a wage cost competitiveness effect. These findings are shown to conform quite well with the predictions of Schumpeterian theory and of certain contributions to ‘new trade theory’ that have stressed the importance of dynamic economies of scale.
