The Two Kornai Effects

Kornai's theories of a “soft budget constraint” study a firm that receives state assistance when expenses exceed revenues. Such assistance is characteristic of classical socialism. It is well known that Kornai contended that a soft budget constraint increases input demands. He also predicted a second effect that has received less attention: input demands exhibit lower price responsiveness. The Second Kornai Effect may be defined in terms of slopes of input demands as Kornai did, or in terms of elasticities. A simple soft budget constraint model is used to review the First Kornai Effect and to examine the two versions of the Second Kornai Effect.     

Dynamic adjustment of supply under Buyers' forced substitution

This paper presents a dynamic version of the static model analysed in Chapter 8 of Kornai (1980). A multi-commodity model is considered, where global excess supply prevails but excess demand persists for certain goods. It is assumed that the goods are storable, and the buyer purchases more than his demand fornon-shortage goods (he makes forced substitution) to satisfy his global demand.This paper investigates the seller's adjustment process and presents alternative assumptions for the supply, the demand, and the allocation rule under which the shortage disappears in a finite period of time.My indebtedness to J. Kornai is multi-sided: it was he, who formalized the theory: it was he, who created the underlying static model, finally the idea of the dynamic analysis is also due to him. I express my obligations to J. Kornai, B. Martos and an anonymous referee for their comments on an earlier version of my paper. Of course, I am alone responsible for any shortcomings of the model.     

Kornai and the vanguard mode of production

In introducing the political power structure into its appropriateplace in his theoretical analysis of 'actually existing socialism'(AES), Jnos Kornai's The Socialist System (1992) was not onlya 'comprehensive synthesis' of his earlier path-breaking studiesbut also qualitatively transformed that analysis. This articleexplores Kornai's presentation of AES as an organic system whose'genetic program' is the vanguard party in power, develops onthis basis the concepts of vanguard relations of productionand the 'specifically vanguard mode of production', and considersthe validity of inferences drawn from the experience of AES.     

Endogenous timing of moves in an asymmetric price-setting duopoly

This paper adds to the growing literature on endogenous timing of decisions in duopolies. We show for a price-setting duopoly game with sufficiently asymmetric and strictly convex cost functions that the less efficient firm moves first while the more efficient moves second with a higher price than the less efficient firm.Received: October 2002, Accepted: March 2003, JEL Classification: D43, L13AttilaTasnádi : attila.tasnadi@wiwi.uni-bonn.deCorrespondence to : Department of Economics, University of Bonn, Adenauerallee 24-42, 53113 Bonn, GermanyAttilaTasnádi : I am grateful to Dan Kovenock and the anonymous referees for many comments and suggestions on an earlier version of this paper.

Exchange rate pass-through in New Member States and candidate countries of the EU

This paper studies the degree of exchange rate pass-through to the prices of imports of some New Member States (NMSs) of the European Union plus Turkey, coming from the euro area. I estimate industry-specific rates of pass-through across and within countries using the methodology proposed by Campa and González-Mínguez [Campa, J.M. and González-Mínguez, J.M. (2006). Differences in Exchange Rate Pass-Through in the Euro Area. European Economic Review, 50, 121–145.] which estimates the short- and long-run pass-through elasticities. I did not find evidence either in favour of the hypothesis of Local Currency Pricing (zero pass-through) or the hypothesis of Producer Currency Pricing (complete pass-through) for all the countries except for Slovenia and Cyprus. With reference to the results by industry, the lowest values for exchange rate pass-through are in Manufacturing sectors. However, I did observe a exchange rate pass-through decline through the pricing chain.     

Law and finance: why does legal origin matter?

This paper assesses empirically two theories of why legal origin influences financial development. The political channel stresses that legal traditions differ in the priority they give to the rights of individual investors vis-à-vis the state and this has repercussions for financial development. The adaptability channel holds that legal traditions differ in their ability to adjust to changing commercial circumstances and legal systems that adapt quickly will foster financial development more effectively. We use historical comparisons and cross-country regressions to assess the validity of these two channels. We find that legal origin matters for financial development because legal traditions differ in their ability to adapt efficiently to evolving economic conditions.

Average Monotonic Cooperative Games

A subclass of monotonic transferable utility (T.U.) games is studied: average monotonic games. These games are totally balanced. We prove that the core coincides with both the bargaining set à la Davis and Maschler and the bargaining set à la Mas-Colell. To obtain this result a technique based on reduced games is used.

Sequentially complete markets remain incomplete

We show by means of an example that the result of Arrow [Arrow, K.J. (1953), Le rôle des valeurs boursières pour la répartition la meilleure des risques, Econométrie, 41–47, CNRS, Paris; translated as The role of securities in the optimal allocation of risk bearing, Review of Economic Studies, 31, 91–96] is problematic when there exist multiple equilibrium continuations to the initial-period component of an intertemporal equilibrium.     

Knowledge interaction towards inclusive learning: Promoting systems of innovation and competence building

This paper draws on recent conceptual approaches to economic growth, in which the accumulation of knowledge is the fundamental driving force behind growth. This fact is reflected in the trend in developed economies towards an increasing investment in advanced technology, R&D, education, and culture. Concepts such as learning ability, creativity, and sustained flexibility gain greater importance as guiding principles for the conduct of individuals, institutions, nations, and regions. It is thus legitimate to question the traditional way of viewing the role that contemporary institutions play in the process of economic development and to argue for the need to promote systems of innovation and competence building based on learning and knowledge networks. This broad concept has motivated the work behind the present work, which reviews the strongest themes of the 4th International Conference on Technology Policy and Innovation (ICTPI), which was held in Curitiba, Paraná, Brazil, in August of 2000. Under the broad designation of “learning and knowledge networks,” the conference brought together a range of experts to discuss technology, policy, and management in a context much influenced by a dynamics of change and a necessary balance between the creation and diffusion of knowledge. While the idea of inclusive development developed in previous conferences entails a process of shared prosperity across the globe following local specific conditions, it is crucial to understand the dynamics of the process of knowledge accumulation, which drives a learning society. Thus, this special issue includes a set of extended contributions to the Curitiba conference that are largely grounded on empirical experiences of different regional and national contexts. The aim of this introductory paper is to set the stage for these contributions, with an original contribution on possible views for the learning society.     

Gender pairing and bargaining—Beware the same sex!

We study the influence of gender and gender pairing on economic decision making in an experimental two-person bargaining game where the other party’s gender is known to both actors. We find that (1) gender per se has no significant effect on behavior, whereas (2) gender pairing systematically affects behavior. In particular, we observe much more competition and retaliation and, thus, lower efficiency when the bargaining partners have the same gender than when they have the opposite gender. These findings are consistent with predictions from evolutionary psychology. Implications of our results for real-world organizations are discussed.     

Bribe-proof rules in the division problem

The division problem consists of allocating an amount of a perfectly divisible good among a group of n agents with single-peaked preferences. A rule maps preference profiles into n shares of the amount to be allocated. A rule is bribe-proof if no group of agents can compensate one of its subgroups to misrepresent their preferences and, after an appropriate redistribution of their shares, each obtains a weakly preferred share and all agents in the misrepresenting subgroup obtain a strictly preferred share. We characterize all bribe-proof rules as the class of Pareto efficient, strategy-proof, and weakly replacement monotonic rules. This class is larger than the set of sequential allotment rules identified in Barberà et al. [Barberà, S., Jackson, M., Neme, A., 1997. Strategy-proof allotment rules. Games Econ. Behav. 18, 1–21].     

The Comparison between Ad Valorem and Unit Taxes under Monopolistic Competition

This paper shows that the welfare dominance of ad valorem over unit taxes under imperfect competition, extends to a Dixit-Stiglitz-type monopolistic competition framework with differentiated products, increasing returns to scale, entry/exit and love of variety. This result is obtained, even though ad valorem taxation leads to increased firm exit compared to the equal-yield unit tax. Yet the smaller tax over-shift, occurring under ad valorem taxation, more than compensates this disadvantage.Acknowledgement Comments and suggestions from Anthony Atkinson, Jürgen Bitzer, Rainald Borck, David Collie, Jan G.

Forecasting the Forecasts of Others in the Frequency Domain

This paper studies a class of models developed by R. M. Townsend (1983, J. Polit. Econ.91, 546–588) and T. J. Sargent (1991, J. Econom. Dynam. Control15, 245–273). These models feature dynamic signal extraction problems and an infinite regress in expectations. This paper uses frequency domain methods to compute an analytical solution to the fixed point problem posed by the infinite regress in expectations. The advantage of a frequency domain approach vis-à-vis a time domain approach derives from the fact that these models produce equilibria with non-fundamental moving average representations, in which market observations do not reveal the underlying shocks to agents' information sets. As a result, decision rules contain moving average components that are more easily handled in the frequency domain than in the time domain.     

The Kornai Effect and Soft Budget Constraints

The Kornai effect refers to situations where soft budget constraints lead to higher input demands. This paper studies the Kornai effect under different scenarios: nonrandom subsidy rate, random subsidy rate, and random and endogenous subsidy rate; and gives sufficient, sometimes necessary and sufficient, conditions for the Kornai effect to exist.     

Aggregation of semiorders: intransitive indifference makes a difference

Summary A semiorder can be thought of as a binary relationP for which there is a utilityu representing it in the following sense:xPy iffu(x) –u(y) > 1. We argue that weak orders (for which indifference is transitive) can not be considered a successful approximation of semiorders; for instance, a utility function representing a semiorder in the manner mentioned above is almost unique, i.e. cardinal and not only ordinal. In this paper we deal with semiorders on a product space and their relation to given semiorders on the original spaces. Following the intuition of Rubinstein we find surprising results: with the appropriate framework, it turns out that a Savage-type expected utility requires significantly weaker axioms than it does in the context of weak orders.We wish to thank Tatsuro Ichiishi, Jorge Nieto, Ariel Rubinstein, Efraim Sadka and especially David Schmeidler and anonymous referees for stimulating discussions and comments.

The role of state enterprises in the transition from command to market economies

In transition from command to market economies total privatization has proved to be impossible to achieve, and a substantial part of large enterprises are likely to remain in full or partial state ownership. Hasty privatization has in many cases even proved to be destructive. There is a need to reconsider the basic approach to transition. Contrary to conventional wisdom prevailing in mainstream economics state-owned enterprises (SOEs) are not necessarily inferior to private firms in economic efficiency. J. Kornai's soft-budget constraint is reconsidered. Two models are suggested under which SOEs may prove to be viable in the long run and serve to promote a smoother physical transition. Under Model One (which is the general case) SOEs are largely separated from the state and operate on the basis of profit maximization. Under Model Two (which applies to certain industries) different objective functions are chosen for purposes of economic efficiency. Finally, preserving SOEs is seen as an alternative means of reducing inequitable income distribution at the source where primary incomes are created.     

ASSESSING THE RELATIVE IMPACTS OF ECONOMIC EDUCATION SCHOLARSHIP: AN APPLICATION OF THE HARZING DATABASE

Despite the rising prominence of economic education scholarship, little work has been done to document how economic education scholarship is faring in the academic world. Unlike prior research in this genre, this study assesses the relative impacts of economic education scholarship by examining published research in (strictly) economic education journals. In order to do so, we use the Harzing database of citations to articles published in (strictly) economic education journals from 1990 to the present. Supporting some of the measures found in prior research, we find that the Journal of Economic Education (JEE) is unambiguously the dominant source of influential scholarship in the field of economic education. Interestingly, the JEE's closest competitors among active economic education journals are the International Review of Economics Education and Computers in Higher Education Economics Research, both of which are published under the auspices of the Economics Network, which is located in the UK. Following these two journals in our ranking is the Journal of Economics and Finance Education, a relatively new journal launch.
