Exchange rates and perfect competition

The purpose of this note is to demonstrate that the commonly held belief that incomplete and perverse pass-through are incompatible with perfect competition is wrong! To this end, we consider two types of firms both operating in two countries. The demand sides of the markets of the two countries are separated and each type of firm produces its good in one of these countries. We study the effect of an exchange-rate change on the competitive equilibrium prices in each country. When producing for the foreign market causes the same costs as producing for the home market then the law of one price holds and an exchange-rate change is completely offset by price changes. Furthermore, when cost functions neither exhibit economies nor diseconomies of scope between producing for the home and producing for the foreign market then prices move in the right directions in response to an exchange-rate change. However, with general cost structures, even in this simple perfectly competitive model, perverse directions of price changes can result from an exchange-rate change.     

From “tax state” to “debt state”

The paper is motivated by Joseph A. Schumpeter's The Crisis of the Tax State. It inquires whether the buildup of government debt in peacetimeprosperity is a threat to the stability, existence or creation of viable tax states. The paper begins by setting out Schumpeter's conception of the tax state and the nature of recent political-economic events which have reinvigorated the concept. Next the paper sets out some simple debt dynamics and sketches a debt-induced business cycle arising from heavy reliance on debt finance in peacetimeprosperity. Finally, the paper assesses threats to the tax state in light of recent work on path dependence and positive feedback. An attempt is made to throw some light on whether the plethora of new, and often small, states spawned by the demise of communism can be viable tax states.Essay on Government, the Tax State and Economic Dynamics submitted to the Third Schumpeter Prize Competition.     

Mutually Destructive Bidding: The FCC Auction Design Problem

In general, synergies across license valuations complicate the auction design process. Theory suggests that a simple (i.e., non-combinatorial) auction will have difficulty in assigning licenses efficiently in such an environment. This difficulty increases with increases in fitting complexity. In some environments, bidding may become mutually destructive. Experiments indicate that a properly designed combinatorial auction is superior to a simple auction in terms of economic efficiency and revenue generation in bidding environments with a low amount of fitting complexity. Concerns that a combinatorial auction will cause a threshold problem are not borne out when bidders for small packages can communicate.     

Full-cost pricing in the classical competitive process: A model of convergence to long-run equilibrium

In the last 10–15 years a lot of attempts has been devoted to study the calssical process of convergence of market prices toward natural prices. The two forces that one has thought could achieve this target were capital mobility, that determines the dynamics of output, and demand-supply forces, that determine the dynamics of prices. In this article a model of classical competition is proposed in which a full-cost pricing mechanism is adopted in the rule of evolution of market prices. An asymptotical stability result of long-run equilibrium is proved for a two-commodity model with and without a final demand.     

Vertical and Horizontal Trust Networks in Bureaucracies: Evidence from the Third Reich

In a seminal contribution to the literature on bureaucracy, Breton and Wintrobe (The Logic of Bureaucratic Conduct: An Economic Analysis of Competition, Exchange, and Efficiency in Private and Public Organization. New York, NY: Cambridge University Press, 1982) develop a model wherein subordinates and superiors in a bureaucratic structure trade with each other to advance the objectives of the superiors. The success of such an organizational arrangement (for superiors) is based upon the development of vertical trust networks in a way that facilitates the promise of informal payments by superiors in return for informal services provided by their subordinates. Breton and Wintrobe [Journal of Political Economy 94 (1986) 905] also provide a theoretical application of their model by describing the Nazi bureaucracy as a conglomeration of competing agencies that zealously carried out the Final Solution to the Jewish question. As an extension, this note develops two compelling empirical examples of vertical and horizontal trust networks within the Nazi regime: Einsatzgruppen As (Special Action Detachments) attempt to liquidate all Lithuanian Jews after the German invasion of the U.S.S.R. in 1941 and the 20 July 1944 attempt to assassinate Adolf Hitler.JEL Classification: D23, D73.     

Strategy-proof and individually rational social choice functions for public good economies

Summary We consider the problem of choosing an allocation in an economy in which there are one private good and one public good. Our purpose is to identify the class of procedures of choosing an allocation which satisfy strategy-proofness, individual rationality, no exploitation and non-bossiness. Any such procedure is a scheme of semi-convex cost sharing determined by the minimum demand principle.I wish to thank Professors Salvador Barbera, Matthew Jackson, Herve Moulin and William Thomson for their helpful suggestions and two anonymous referees for their detailed comments.

Finance,investment and innovation: A theoretical and empirical comparative analysis

The paper compares the relative efficiency of country models in the relationship between finance and investments. Results, confirmed under three different panel data estimates (Arellano-Bond GMM method, random and fixed effect estimates) suggest that: i) the UK thick market reduces informational asymmetries for large firms and for those firms providing good signals to shareholders; ii) the Japanese vertical (between firms and banks) integration and horizontal (among firms) integration almost eliminates financial constraints (the horizontal integration effect) and equates agency costs across firms (the vertical integration effect). These results are consistent with the short-termist hypothesis which assumes that the Japanese economic system can process information more efficiently reducing managerial myopic behaviour and thereby determining positive effects on long term growth.

Sector-specific capital, “Bang-bang” investment,and the Filippov solution

Bang-bang investment in a two-sector growth model with immobile capital is rational and leads to a unique and globally stable long-run equilibrium along a sliding trajectory. This steady state coincides with the stationary equilibrium in the traditional model with non-sector-specific capital.This article was written while the authors were visiting scholars at Cornell University.

“Buy Domestic” Campaigns and Optimal Tariffs

This paper attempts to analyze the strategic use of optimal tariffs and to examine the effects of national bias on the optimal trade policy and social welfare in a two-country, two-good, price competition model derived from Neven et al. (1991). The major findings are as follows. (1) If all consumers prefer the domestic good, then buy domestic campaigns will decrease the prohibitive tariff rate and increase local welfare. (2) If at least some consumers prefer the foreign good, but not to a great extent, then buy domestic campaigns will not change the optimal tariff rate, but may improve local welfare. (3) When all consumers greatly prefer the foreign good, then promotion of buy domestic decreases the optimal tariff rate, but it cannot improve social welfare. With this framework, we also prove that buy domestic campaigns serve as a substitute for tariffs with respect to a strategic trade policy.     

Individual Decision Making in a Negative Externality Experiment

The experimental treatments analysed in this paper are simple in that there is a unique Nash equilibrium resulting in each player having a dominant strategy. However, the data show quite clearly that subjects do not always choose this strategy. In fact, when this dominant strategy is not a focal outcome it does not even describe the average decision adequately. It is shown that average individual decisions are best described by a decision error model based on a censored distribution as opposed to the truncated regression model which is typically used in similar studies. Moreover it is shown that in the treatments where the dominant strategy is not focal dynamics are important with average subject decisions initially corresponding to the focal outcome and then adjusting towards the Nash prediction. Overall, 66.7% of subjects are consistent with Payoff Maximization, 27.8% are consistent with an alternate preference maximization and 5.6% are random.

Ein Entscheidungsmodell für Konsumieren und Sparen

Summary The present study analyses the simultaneous problem of consumption and saving by means of a consistent demand system; for this purpose the linear—expenditure—system (LES), developed by R. Stone, has been modified and used as a methodological base. Saving takes, for the sake of operationality, the character of a consumer—good and becomes an argument of the utility function. The usual neoclassical assumption of utility maximization allows the derivation of a linear expenditure system of consumption and saving (LESSC) when prices and income are given. The simultaneous LESSC-model has remarkable weaknesses, however: the assumption of certainty, the static character of the model, the disregard for major savings—motives and private expenditure on homebuiding led to bad elasticity—estimates. The assumpion of directly—additive utility functions causes furthermore collinearity between income—and price—elasticities such that the meaning of the derived elasticities is greatly reduced.The income—elasticities derived from the LESSC are positive throughout but show a remarkable variance. The calculation of the Friedman—bias demonstrates a rather strong bias due to the assumption of certainty. A modification resulted in income—elasticities of private consumption and savings of around 0,93 (unmodified: 0,88) and 1,41 (unmodified: 1,76). The demand for consumption goods of great necessity was income—inelastic whereas the demand for goods of less importance to survival was income—elastic. An analysis of income—elasticities of the disaggregated system and the relation between transitory components of consumption and income existing in Austria gave the impression that unexpected changes in income are not only reflected in saving but also in changes of the consumption—structure.The respective price—elasticites are all negative and smaller than 1. For less important consumption—goods lower price—elasticities have been measured and for easily substitutable goods higher ones. Marked crossprice—elasticities could only by discovered with clothing and food products. Generally it can be said that an increase in prices of goods of the daily needs hits both the expenditure on easily substitutable consumption goods and causes dissaving.A comparison with the elasticities calculated through OLS shows a greater reliance of LESSC—elasticities as far as data of differing aggregation levels are concerned.

The “Dorfman Steiner” rule

Conclusion When this research was started, it was guessed that the Dorfman-Steiner rule would lose its relevance in an intertemporal setting. This belief has turned out to be false: along the optimal paths ofp (t) ands (t), and must be equal. The only difference with the Dorfman-Steiner result is that they will be different from unity.The author is chargé de cours at the Faculté Universitaire Catholique de Mons (Belgium).

Fully endogenous mechanism selection on finite outcome sets

Summary This paper defines a choice process over social outcomes in which agents choose the institutional rules ormechanisms themselves without outside interference. Truly endogenizing the mechanism selection process in this way, however, involves facing an infinite regress problem in which outcomes are chosen by games which are themselves chosen by games, ad infinitum. This paper allows the possibility of such an infinite regress which we callfully endogenous mechanism selection.We introduce the notion ofFree Choice which restricts the class of mechanisms in the regress to those which prevent agents from being locked in to an equilibrium outcome by the actions of others. Under this condition, the infinite regress is shown to get truncated with the number of selection iterations endogenously determined. It turns out that the outcomes resulting from a Free Choice-constrained regress are (Weakly) Pareto optimal; in particular, these outcomes solve a weighted Rawlsian Maxmin criterion. We also show that these outcomes are invariant to the equilibrium concept used to evaluate games in the regress.This paper is based on the author's dissertation from the University of Minnesota (November, 1989).I am very grateful for the guidance, advice, and encouragement from my advisor, Marcel K. Richter, and for the many helpful suggestions from David Levine.

Agency in a market setting

This paper examines a market in which a continuum of principals and agents interact in a game. Principals offer contracts while agents decide on sets of acceptable contracts. A mechanism from a class satisfying efficiency, unbiasedness, and continuity properties then matches principals and agents. With risk neutral agents, when the contribution of principals and agents to the total gains from trade in a pairing are additively separable, the equilibria of the game coincide with the competitive equilibria for the market. In particular, all contracts used in Nash equilibrium induce first-best effort levels. Both principals and agents have exogenous opportunities outside this market. In equilibrium, agents have endogenously determined outside opportunities available from employment by another principal, and this may be the binding participation constraint in a principal-agent pairing. The results are extended to special non-separable cases and to the case of identical risk averse agents.We are grateful to seminar participants at Indiana University, the University of Kentucky, and Vanderbilt University for comments on earlier versions of this work. Referees' comments led us to generalize the model and to more clearly specify the point of the paper.

Hugging Trees: Claiming de Facto Property Rights by Blockading Resource Use

This paper explores conflicts between two groups,the industry and theenvironmentalists, over whether an indivisible resource (e.g., an ancient tree) should be harvested or preserved. In a complete information war ofattrition the environmentalists' willingness to blockade harvest attemptsmay control resource use as effectively as if they held property rights. Optimal government intervention will override this ability for somebenefit/cost combinations but may augment it for other combinations.Introducing uncertainty about the environmentalists' benefits results inextended disputes and consequent lack of efficiency. Governmentintervention for welfare reasons generally reduces these efficiencylosses.     

The Coming Slavery: The Determinism of Herbert Spencer

Herbert Spencer (1820–1930) believed that Victorian Britain was moving toward a society of total regimentation (slavery). This movement was part of a cosmic process of evolution and dissolution. While the long-run (but not ultimate) destination of society was a higher form of social organization based on voluntary and complex interpersonal relationships, the immediate tendency was retrograde—a movement away from the liberation of mankind from the bondage of previous eras. This Article explores (1) the reasons for the retrograde movement, (2) its inevitability, and (3) the role of ideas in the process. The general conclusion is that in an effort to explain the general movement of social institutions and practices, Spencer develops a mechanical and deterministic approach which undermines his ability to pass normative judgements on changes in society.     

Friedrich Hayek's Theory of Spontaneous Order: Two Problems

The paper finds Hayek's basic building block, the natural/artificialcontrast, to be illuminating. But the manner in which Hayek classifiesentities according to the contrast generates two major problemsin his socio-economic theory. First, Hayek's concept designconfuses the technical construction of, e.g., a chair with thedeliberate organization of division of labor within the firm.Second, Hayek's notion spontaneous order fails to note twokinds of natural order — firms and markets.
