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).

On Intertemporal Subsidy-Free Prices and Economic Depreciation: Constrained Market Pricing Revisited

The constrained market pricing approach to regulating monopolies maintains that prices should be subsidy-free, lying between the often expansive bounds of stand alone and incremental costs. For a simple two-good/two-period model of a monopolist subject to a zero profit constraint, it is shown that subsidy-free prices are those which rise to the amortized opportunity cost of the currently optimal asset configuration required to meet both current and future demand, providing—in some circumstances—justification for accelerated depreciation. Such intertemporal subsidy-free prices recognize that the stand alone cost of existing assets to current consumers depends on the value of those assets to future consumers. Hence, if a feasible resale price for the fixed costs of capacity exists within or between periods, then intertemporal stand alone costs and intertemporal incremental costs are driven to equality.     

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.     

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.     

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.     

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.     

Nachfragesysteme für österreich

Summary This paper gives an empirical reexamination of the Linear-Expenditure-hypothesis for Austria. It starts with a brief theoretical discussion of the principal properties and restrictions of the Linear-Expenditure-System (LES). To obtain empirical estimates of the parameters of the LES two different estimation procedures are applied, i.e. the original method used byStone and a simplified version of the Systems-Least-Squares-approach (following theMarquardt-algorithm). There are no essential differences between these estimates. They all seem plausible and satisfy the theoretical restrictions.Usually the stability (i.e. time-invariance) of the parameters is accepted without proof. Using the Moving-Window-Regression-technique, however, most of the estimates vary significantly in time. To obtain a direct proof of the time-dependence of the parameters the LES is reestimated now including trend-factors. Especially results considering time-dependent marginal-budget-shares are considerably better than the static-model results.The conclusion of this paper is that the static version of the LES does not explain the consumer behaviour in Austria and that much more effort should be spent on the estimation of dynamic demand systems.     

Regulatory regimes in the electric power industry: Implications for capacity

We construct a model of the electric power industry which consists of two utilities faced with uncertain demand and a variety of regulatory regimes. Two technologies are considered, base-load and peaking, and the transfer of bulk electricity among utilities is permitted. The purpose of the paper is not to determine optimal regulatory regimes but to provide a framework for analyzing existing and contemplated regulatory initiatives. The conclusions are that long run survival mandates an authorized rate of return above the cost of capital and that excess investment will result. Furthermore, it is highly unlikely that current regulatory instruments such as Used and Useful, distribution of profits from bulk sales, and pricing of wholesale electricity can lead to a socially optimal capital stock.     

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.

The Regulation of Private Schools Serving Low-Income Families in Andhra Pradesh,India

This paper sets out some findings of a research project carried out in private unaided schools in low-income areas of Hyderabad, India. The part of the research project documented here was designed to examine the question: Is the regulatory regime conducive to entrepreneurial action and market discovery with particular reference to the low-income schools in Hyderabad. This paper is narrowly focused, setting out the results of pattern matching empirical data with the Austrian economic concepts of entrepreneurship, rivalry, and market discovery. The research discovered that two regulatory regimes exist, one that is set out on paper in the Education Acts and associated rules, and another that operates in practice. That is, there is a combination of regulations on paper and regulations existing in an extra-legal sector. Generally it was found that the regulations in practice are consistent with market principles. Conversely the regulations set out on paper are not conducive to entrepreneurial innovation and market discovery. Recommendations for potential policy initiatives include the possibility of legitimising the extra-legal sector by introducing self-regulation possibly via self-evaluation systems for the private unaided schools.     

Marktstruktur und Preisverhalten in der österreichischen Industrie

Summary Being part of a larger investigation concerning forms and intensity of competition in the Austrian economy this paper deals with the characteristics of market structure and pricing behaviour in the industrial sector. Mainly based on a detailed questionnaire this study is representative for the group of larger Austrian industrial enterprises (sales of more than 100 Mill. AS) which produced more than two thirds of total industrial ouput. According to this study the dominant market structure of the Austrian industry is that of a close oligopoly. The subjective estimation of the price elasticity of demand by the firms participating in our survey was generally very pessimistic, being the lower the larger the market share of the respective firm.The most common principle of price formation for new products in the Austrian industry is a system of flexible full cost pricing, meaning cost orientation plus variable profit margins. Our study also shows that a large majority (60% resp. 80%) of the enterprises under investgation use discount, i.e. price differentiation in their pricing policies. These aspects indicate that-in line with marginalistic theories — demand situations obviously exercise a substantial influence on pricing behaviour. Considering the causes for price changes, however, cost oriented influences were clearly dominating. This stresses the great importance of the Austrian pricecontrol mechanism, the Paritätische Kommission, the institutionalized form of incomes policy in Austria.An econometric analysis of the process of price formation in the Austrian industry showed that the main factors of price changes were changes in labour costs and in international price levels, especially in the level of export prices. Our investigation also dealt with the question, whether differences in market-structure result in different, responses to demand fluctuations. Considering both the concepts of actual and potential competition it can be shown that enerprises in a more competitive situation react towards changes in demand conditions in a more stabilizing way that monopolistic firms: The reduce prices earlier in recession and they react to boom periods by expanding their capacities rather than by raising prices. Market structure and the intensity of competition thus seem to influence the position of the Phillips-curve in an economy.     

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 rational regulator's pricing response to enhanced opportunities to “bypass” the public telephone network

Various technological innovations make it profitable—given regulated service prices—for large business customers of local telephone companies to invest in private equipment and reduce their reliance on the public telephone network. Such bypass possibilities reduce demands and increase demand elasticities for regulated business services. The politics of state telephone regulation motivate two specifications of regulatory objectives—specifications designed to reveal positive implications of bypass for regulated prices. One views the regulator as practicing so-called residual pricing, and a generalization assumes that the regulator balances the interests of competing pressure groups. Implications for interpretation of political rhetoric and for future modeling are discussed.     

Measuring the severity of unemployment

A social-welfare (illfare) function framework is applied to compare two demographic groups as to the severity of their unemployment experience. This is based on the assumption that for each individual the disutility of unemployment is an increasing and convex function of spell length. The very concept of spell length and its distribution, however, is not unambiguous. In contrast to previous literature which focuses exclusively on the interrupted spell length in a stock of unemployed, we stress the usefulness of the concept of complete spell length in a cohort of unemployed. We establish an equivalence relationship between second-degree dominance in the cohort and first-degree dominance in the stock. For specific illfare functions the disutilityU(x) when applied to the cohort and the disutilityU(x) when applied to the stock will produce the same value of aggregate welfare (illfare).     

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.

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.     

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.

On the strategic inconsistency of the meta-rights approach

Among many attempts to circumvent Sen's impossibility result Gibbard's theory of alienable rights has attracted attention of many researchers. Basu's (1984) theorem essentially depends on a Nash-type equilibrium concept. In this paper we introduce an alternative behavioral assumption where individuals have conjectures about the responses of others and investigate the robustness of Basu's result under this new solution concept. We also examine a possibility of coalition formation and cooperation under the meta-rights approach.For helpful discussions I would like to thank Rajat Deb, Joseph Greenberg, and Shlomo Weber. I am also indebted to an anonymous referee of this Journal for many valuable comments.
