MONOPOLY POWER AND DOWNWARD PRICE RIGIDITY UNDER COSTLY PRICE ADJUSTMENT

A method of 'backward deduction' is used to analyse the decisions of a firm, setting price and quantity before demand observations are made, with the option to adjust price at a cost after demand is observed. It is shown for such a firm that the events of (1) downward price rigidity; (2) overproduction; and (3) a high degree of monopoly power are closely related. The paper distinguishes itself from the previous literature on costly price adjustment in its treatment of disequilibrium situations and focus on monopoly power in relation to price rigidity. The main results are obtained for a linear demand curve and a uniform demand distribution.     

COLLUSION,FLUCTUATING DEMAND,AND PRICE RIGIDITY*

We study an infinitely repeated Bertrand game in which an i.i.d. demand shock occurs in each period. Each firm receives a private signal about the demand shock at the beginning of each period. At the end of each period, all information but the private signals becomes public. We consider the optimal symmetric perfect public equilibrium (SPPE) mainly for patient firms. We show that price rigidity arises in the optimal SPPE if the accuracy of the private signals is low. We also study the implications of more firms and firms' impatience on collusive pricing.     

价格信息成本与价格离中现象

该文在Varian(1980)中引入消费者价格信息成本和信息成本的分布,采用Janssen和Moraga(2000)的对称混合策略均衡定义,同时内生化了消费者的信息行为和厂商的定价行为,确定了Varian(1980)中的知情消费者比例,证明了厂商定价正期望利润均衡的存在性.该文证明了,在不完全价格信息条件下,市场普遍存在知情消费者,从而该文加强了Varian(1980)的结论.     

TAXES AND ENTREPRENEURSHIP IN OECD COUNTRIES

I examine how taxes and tax progressivity affect two different types of entrepreneurship—established business ownership and nascent entrepreneurship—in a large group of Organization for Economic Co‐operation and Development countries, using 2000–2009 macro‐level Global Entrepreneurship Monitor data. Empirical evidence from Arellano‐Bond generalized method of moments estimation suggests that higher tax progressivity exerts a negative influence on nascent enterprises but appears to have no impact on established business ownership. Changes in marginal and average tax rates are found to have no significant influence on either type of entrepreneurship. The most important contribution of the article is the comparison of tax impacts on actual and nascent entrepreneurship rates. (JEL H24, H29, M13, M19)     

DYNAMIC ENVIRONMENTAL TAXES UNDER INTERNATIONAL DUOPOLY

This paper studies a dynamic game of environmental taxes between two countries in the absence of explicit trade policies when both governments and firms act strategically. We demonstrate that the environmental tax in the steady‐state equilibrium in a dynamic environmental tax game is lower than that in a static environmental one. Therefore, the dynamic behaviour of the governments results in an increase in the environmental damage. Further, as a result of international cooperation on environmental taxes between two countries in the beginning of policy competition, there is an increase in the optimal environmental tax. This implies that it is important to set cooperative environmental taxes in the beginning of policy competition because non‐cooperative environmental taxes in the dynamic game result in the race‐to‐the‐bottom, which does not lead to environmental improvement.     

PRICE ANALYSIS AND A SYSTEM OF PRICE STATISTICS

For some considerable time the interest in price statistics has mainly been focused on their use as "intermediate goods". The requirements of a system of price index numbers which have to be established in this connection are largely in the field of statistical coordination (integration of statistics on quantities, values and prices).
Recently the inflation problem has given rise to an increased interest in price statistics as "final goods". A meaningful analysis of inflation will devote attention to the relation between input prices and output prices. In this article several versions of an analysis of prices of final demand categories based on an ordinary Leontief input-output scheme are presented and the needs for price statistics are discussed. In fact a self-contained system of price statistics emerges from the price analysis.
There is a difference in the nature of the price index numbers required in compiling input-output tables in constant prices (Paasche) and that in the case of price analysis (Laspeyres). However the need for price observation runs largely parallel because in both cases the same detailed information on price developments will probably be used.
Price analysis gives the possibility of a step-by-step approach in building up a system of price index numbers.     

RENOVATIO MONETAE: WHEN GESELL TAXES WORKED

Gesell taxes on money have recently received attention as a way of alleviating the zero lower bound on interest rates. Less known is that such taxes generated seigniorage in medieval Europe for around two centuries. When a Gesell tax was levied, current coins ceased to be legal and had to be exchanged into new coins for a fee. Using a cash-in-advance model, we analyze under what conditions agents exchange coins and the tax generates revenues. A low exchange fee, high punishments for using old coins, and a long time period between re-mintings induce people to use new coins.     

FUEL TAXES AND COINTEGRATION OF ENERGY PRICES

Creating a successful energy tax policy requires understanding the markets that the energy policy targets. This paper analyzes coal, natural gas, and oil markets to determine the extent to which these fuel prices move together. Results indicate that a stable long-run relationship between coal and oil prices existed until 1974 and that this relationship changed after 1974. The long-run relationship between coal, natural gas, and oil prices implies that a single fuel tax in these markets would not be effective as a single tax policy. Similarly, an equal percentage tax on these energy sources, which does not change relative prices initially, would not keep relative prices unchanged in the long run. Energy policy must take account of the long-run relationship between different energy prices. Otherwise, the long-run results of energy policy could be quite different than intended .     

TAXES AND INCOME: A MICROUNIT ANALYSIS

The paper details the methodology used and the results obtained in a recently completed study of the total U.S. tax burden based on microdata survey files. The method of constructing the data base—the 1966 MERGE file—is discussed, and the needed imputations and adjustments to income and taxes to bring the file totals up to national income aggregates are described. An explanation is included of adjusted family income, a unique income concept used in the study to measure and compare tax burdens.
The study involved the evaluation of errective tax burdens under eight different assumptions regarding the incidence of the various major taxes. Those assumptions are detailed and the results of the study are presented. The essential conclusion of the study is that the overall impact of the tax system is virtually proportional for 90 percent of the families in the United States regardless of the incidence assumptions used. However, substantial differences in tax burdens were found among various subgroups of the population.     

QUALITY-CORRECTED PRICE CAPS

Although price caps have desirable efficiency properties, it is well known that they may create incentives for a regulated firm to attempt to lower its costs via reductions in service quality. Thus, the regulators often employ quality standards or other methods designed to have allowed prices reflect delivered service quality levels. In this paper, we present a system of quality‐corrected price caps that results in efficient pricing and quality provision.
