Is Technological Progress Pareto-Improving for a World with Global Public Goods?

This paper investigates the welfare effects of unilateral or multilateral technological progress in a world with global public goods. We focus on the consumption relation between the private and the public good, and then show that technological progress may beself-centered (benefit oneself but harm others), self-sacrificing (harm oneself but benefit others), or self-defeating (harm all) if two goods are substitutable. In addition, any type of technological progress improves every countrys welfare if the private and the public good are close complements.     

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.     

Incentive compatibility and the quantity-setting competitive firm under demand uncertainty

This paper examines the tie between the popular black box neoclassical quantity-setting firm under demand uncertainty and a firm with a rudimentary but explicit employee relation organizational structure in which workers are offered fixed wages for following management directives. Surprisingly, the quantity-setting firm unambiguously mimics optimal employment relation hiring and work rules when the contract is incentive-compatible ex post. The attitude toward risk is shown to be the key determinant of whether or not the quantity-setting firm replicates the optimal employment relation contract when ex post incentive-compatibility is relaxed.     

Convergence empirics across economies with (some) capital mobility

This paper uses a model of growth and imperfect capital mobility across multiple economies to characterize the dynamics of (cross-country) income distributions. This allows convenient study of the convergence hypothesis, and reveals, where appropriate, polarization and clumping within subgroups. The data show little cross-country convergence; instead, the important features are persistence, immobility, and polarization, exemplified by convergence club or twin peaks dynamics.     

Knowledge Questions: Hayek,Keynes and Beyond

This paper discusses the knowledge problem in terms of both the use and generation of knowledge. This is analyzed in the context of Hayek's failure to respond to the Keynes Challenge—the claim that markets fail to produce relevant knowledge—by suggesting that in the aftermath of The General Theory he was not well-positioned to address that problem. Ironically, his post-World War II work in cognitive psychology, The Sensory Order, offers a theory of the generation of knowledge which can provide a useful analogy for understanding the generation of market-level knowledge.     

Efficient Management of Product Durability and Recyclability under Utilitarian and Chichilnisky Preferences

In a dynamic general equilibrium vintage model we explicitly consider the relationship between the product attributes durability and recyclability. Efficient management in the case that green design markets fail is analyzed both under Utilitarian and Chichilnisky preferences. It turns out (a) that durability may be inefficient even in a perfectly competitive economy in which environmental externalities are absent, (b) that the efficiency-restoring tax-subsidy schemes crucially depend on the kind of preferences, and (c) that changing the property rights for consumption goods and residuals is a promising policy option to overcome market failure independent of the kind of preferences.     

Democracy and Opinion Falsification: Towards a New Austrian Political Economy

Hayek's view of democracy as a process of forming opinion is taken as a starting point for inquiring into issues largely neglected by Public Choice and Constitutional Economics. In an Austrian perspective, fallible individual knowledge, political entrepreneurs and dissenting minorities attain a distinctive role in the process of political competition. Based on the observation that political opinions consist of preferences and theories, the concept of opinion falsification is introduced. It is a spontaneous result of social interaction creating preference falsification - the disguise of true feelings, but also knowledge falsification – the discovery of false beliefs. Democratic constitutions can limit the scope of preference falsification and increase the potential for knowledge falsification, thus supporting Hayek's view that it is in its dynamic, rather than its static, aspects, that the value of democracy proves itself.     

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.

On the generic nonconvergence of Bayesian actions and beliefs

Summary SupposeY _n is a sequence of i.i.d. random variables taking values in Y, a complete, separable, non-finite metric space. The probability law indexed by, is unknown to a Bayesian statistician with prior, observing this process. Generalizing Freedman [8], we show that generically (i.e., for a residual family of (,) pairs) the posterior beliefs do not weakly converge to a point-mass at the true. Furthermore, for every open setG , generically, the Bayesian will attach probability arbitrarily close to one toG infinitely often. The above result is applied to a two-armed bandit problem with geometric discounting where armk yields an outcome in a complete, separable metric spaceY _k. If the infimum of the possible rewards from playing armk is less than the infimum from playing armk', then armk is (generically) chosen only finitely often. If the infimum of the rewards are equal, then both arms are played infinitely often.     

Land use, biodiversity, and sustainability

We focus on the effects of deforestation for agricultural purposes on biodiversity. This topic has been dealt with in the recent literature where forested land and biodiversity are treated as synonyms. In contrast to that, this paper distinguishes between forested land and forest itself, the latter being interpreted as a measure of biodiversity. The regenerative capacity of forests is modeled as a function of the own stock and of the habitat size. In particular, the threat of a given minimum viable population to be achieved in the course of the reduction of habitats is taken into account. The corresponding structure of a sustainability indicator is elaborated.     

On the Durability of King and Council: The Continuum Between Dictatorship and Democracy

In practice one rarely observes pure forms of dictatorship that lack a council, or pure forms of parliament that lack an executive. Generally government policies emerge from organizations that combine an executive branch of government, the king, with a cabinet or parliamentary branch, the council. This paper provides an explanation for this regularity, and also provides an evolutionary model of the emergence of democracy that does not require a revolution. The analysis demonstrates that the bipolar king and council constitutional template has a number of properties that gives it great practical efficiency as a method of information processing and as a very flexible institutional arrangement for making collective decisions.     

Chasing Phantoms in a Hollow Defense of Coase

Patrick Gunning refuses to acknowledge the most salient arguments against the Chicago law and economics case for negligence made by Austrian economists. Because of this, he makes the same errors in his defense of Coase that permeate the Chicago paradigm. In particular, his defense of Coasean type analysis completely ignores Austrian cost theory, i.e., that all economically relevant costs are strictly subjective and therefore conceptually impossible to measure. He also fails to grasp the implications of disequilibrium market process theory for the use of any kind of least-cost-avoider rule in the economic analysis of the law. As a result, Gunning's defense of Coase suffers from the same pretense of knowledge as the analysis that he is defending.     

Risk Aversion, Intergenerational Equity and Climate Change

The paper investigates a climate-economy model with an iso-elastic welfare function in which one parameter measures relative risk-aversion and a distinct parameter measures resistance to intertemporal substitution.We show both theoretically and numerically that climate policy responds differently to variations in the two parameters. In particular, we show that higher but lower leads to increase emissions control. We also argue that climate-economy models based on intertemporal expected utility maximization, i.e. models where = , may misinterpret the sensitivity of the climate policy to risk-aversion.     

Framing Effects in Public Goods Experiments

Three effects of apparently superficial changes in presentation (framing effects in a broad sense), were replicated together in the same repeated linear public goods experiment with real financial incentives. First, 32 repetitions were presented as four phases of 8 repetitions with a break and results summary in between. Contribution levels decayed during each phase but then persistently returned to about 50% after each re-start. Second, subjects contributed more when the payoff function was decomposed in terms of a gift which is multiplied and distributed to the other players, rather than the equivalent public good from which everyone benefits. Third, subjects contributed more following a comprehension task which asks them to calculate the benefits to the group of various actions (the We frame), rather than the benefits to themselves (the I frame). These results suggest that aspects of presentation may have strong and replicable effects on experimental findings, even when care is taken to make the language and presentation of instructions as neutral as possible. Experimental economists should therefore give careful consideration to potential framing effects—or, better still, explicitly test for them—before making claims about the external validity of results.     

Learning for Innovation and the Skill Premium

The computer revolution took very long to pay off in productivity growth in the computer-using sectors. The relative wage of skilled workers, however, has risen sharply from the early days of the computer revolution onward. As skilled workers wages reflect their productivity, the two observations together pose a puzzle.This paper provides a micro-based explanation for the long diffusion period of the computer revolution. The general equilibrium model of growth zooms in on the research process and provides an explanation for sluggish growth with booming relative wages of the skilled. Technological progress in firms is driven by research aimed at improving the production technology (innovation) and by assimilation of ideas or principles present outside the firm (learning). A new General Purpose Technology (GPT) like the computer revolution generates an initial slowdown in economic growth and an increase in the skill premium.Acknowledgement I am indebted to Theo van de Klundert for suggestions and encouragement.

Power,luck and the right index

Summary We have pointed out the theoretical drawbacks of the traditional indices for measuring a priori voting power inasmuch as they are implied in considering the coalition value a private good. This criticism caused us to view the coalition outcome as a public good. From this aspect and additional considerations with respect to power, luck, and decisiveness, we obtained a story describing the characteristics of an adequate measure of a priori voting power. These characteristics were found to be fulfilled by an index presented by Holler (1978). Through the above analysis this index has received its theoretical justification. An independent view of this index was then provided by means of an axiomatic characterization. This characterization makes possible abstract comparison of the index with previously established private good indices.While we have restricted our attention to simple games, the index presented can be generalized to provide a value on games in characteristic function form. We leave this topic for future conideration.     

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.     

“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.

Austrian economic policy

Zusammenfassung Die österreichische Wirtschaftspolitik wird in Österreich vielfach als austro-keynesianisch etikettiert. Der vorliegende aufsatz versucht zu zeigen, daß das Keynesianische dieser Politik nicht in einer Stop-and-go-Politik besteht, was üblicherweise als Keynesianismus bezeichnet wird. Vielmehr zielt die österreichische Wirtschaftspolitk darauf ab, intrinsische Instabilitäten des Marktprozesses als Folge von Unsicherheiten oder wechselnden Erwartungen durch gesamtwirtschaftliche Arrangements zu reduzieren: Sozialpartnerschaft, stabiler Finanzsektor, Unabhängigkeit der Investitionsentscheidungen von monetären Faktoren sowie Dominanz automatischer Stabilisatoren. Diese Reduktion von Marktinstabilitäten kann als fundamentale Politikempfehlung Keynes' angesehen werden.Der Terminus Austro in der Bezeichnung der österreichischen Wirtschaftspolitik weist darauf hin, daß es ein hausgemachtes Konzept ist, welches neben keynesianischen Elementen auch klassische Relikte, neoklassische Erweiterungen, monetaristische Vermutungen oder einfach Wirtschaftspolitik à la Hausverstand beinhaltet. Dies gilt insbesondere für eine Vielzahl von selektiven Eingriffen wie Investitions-, Spar- oder Exportförderung. Gemeinsam ist diesen selektiven Eingriffen, daß sie üblicherweise als Erklärungen für die Erfolge der österreichischen Wirtschaftspolitik herangezogen werden; der konkrete Beweis hiefür steht jedoch aus.Der Aufsatz unternimmt den Versuch, das austro-keynesianische Konzept theoretisch wie auch empirisch kritisch zu prüfen.
