Abstract. The recent literature on the welfare cost of inflation emphasizes inflation's effect on the variability of relative prices. Expected and unexpected inflation have both been proposed to increase relative price variability (RPV) and, thereby, to distort the information content of nominal prices. This paper presents new evidence on the impact of inflation on RPV in Germany. Our results indicate that the influence of expected inflation disappears if a credible monetary policy stabilizes inflationary expectations on a low level. Yet the significant impact of unexpected inflation suggests that even low inflation rates can lead to welfare losses by raising RPV above its efficient level. 相似文献

The general model of social learning with irreversible investment and endogenous timing is analyzed for any distribution of private informations. Strategic complementarities and multiple equilibria appear which are generated solely by information externalities. Different equilibria generate strikingly different amounts of information. The impacts of various assumptions (bounded beliefs, large number of agents, discrete time and short periods) are examined carefully. The properties are robust to the introduction of observation noise with a continuum of agents. 相似文献

Over the last decade, the public sector in Mexico experienced substantial fiscal reform, divestiture of public enterprises,
and the elimination of many regulations affecting pay and employment. This study analyzes the changes in the public/private
sector differences in wages during the 1987–1997 period. The results from analyzing microdata from the Encuesta Nacional de
Empleo Urbano show that relative public sector wages increased from 1987 to 1997. Most of the relative wage increase in the
public sector can be explained by increases in the price of skills and by changes in sorting across sectors. The results have
important public policy implications since they suggest that public sector workers earn more and their wages have grown faster
than those of their private sector counterparts. As such, policies contemplating public sector reform should take into account
the effect of these measures on the inter-sectoral income distribution and the overall economic growth.

This paper considers educational investment, wages and hours of market work in an imperfectly competitive labour market with heterogeneous workers and home production. It investigates the degree to which there might be both underemployment in the labour market and underinvestment in education. A central insight is that the ex post participation decision of workers endogeneously generates increasing marginal returns to education. Although equilibrium implies underinvestment in education, optimal policy is not to subsidise education. Instead it is to subsidise labour market participation which we argue might be efficiently targeted as state-provided childcare support. 相似文献

Overlapping generations model of fiat money yields an infinity of competitive equilibrium solutions, only one of which is stationary. Economies reported in this paper involved a sequence of overlapping generations of three or four individuals; each individual lived for two periods. In their young age individuals were endowed with chips that could be traded for fiat money wish the individuals of the old generation. In their old age, individuals could exchange their units o flat money for the consumption good. Results of the experiments exhibit some support for the stationary solution. The results are robust to two designs of exchange institutions (double oral auctior and supply schedule auction) and to two different endogenous ways of converting money into chips at the end of the game (average price prevailing during the last period the game is actually played and the average price forecast made during the last period the game is actually played).A preliminary version of this paper was presented at the meeting of the Economic Science Association and at the Federal Reserve Bank of Minneapolis. The authors are grateful for comments received from various participants at both presentations.

This paper investigates the relationships between stock returns, changes in production, and changes in interest rates in three European countries: France, Germany, and the United Kingdom. The results obtained using annual data are much more conclusive than those obtained using quarterly data. Stock returns are affected by current changes in interest rates and by future changes in production. The dependence on changes in interest rates seems to be higher than on changes in production. Furthermore, the influence of future changes in production on stock returns diminishes substantially when contemporaneous changes in interest rates are taken into account. With reference to these points, the European markets behave in a similar fashion, but are in sharp contrast with the U.S. market.I am very grateful to Kay Davidson, Patric Hendershott and two anonymous referees for useful comments and suggestions. I am solely responsible for all remaining errors. 相似文献

The price-oriented experience curve has been widely utilized as a model to design marketing strategies. Yet, it is cost over which many firms exercise the most control. This article explores the cost-oriented learning curve in conjunction with the product life cycle model as joint strategy constructs. Implications of variations in the learning curve parameters are examined. 相似文献

In this paper we investigate the efficiency of a class of transaction-generating algorithms, originally suggested in Bollerslev and Domowitz (1993). Our comparison utilizes real transaction data recorded over Reuters D2000-2 electronic broking system for 7 h in June 1993 and transaction data generated from FXFX quotations over an identical period. Results suggest that, at this high-frequency data sampling, the performance of these transaction-generating algorithms is poor, with the most likely explanation of this outcome due to the high-frequency characteristics of FXFX spreads and quotation intensity. 相似文献
