Advertising and Competition for Market Share between a New Good Producer and a Remanufacturer

We study the strategic interaction between a new good producer and a remanufacturer who use advertising campaigns to compete for a dominant share of the market for a certain good. Each firm chooses one of three possible strategies for running its advertising campaign. The two rival firms care only about capturing a dominant share of the relevant market. Hence, if a firm expects to capture dominant market share with probability p ∈ [0, 1], then its payoff in the game we study is also p. Our analysis leads to four results. First, we provide the normal form representation of the game between the new good producer and the remanufacturer. Second, we specify the game in matrix form. Third, we indicate what happens at each stage of the elimination of strictly dominated strategies. Finally, we show that the iterated elimination of strictly dominated strategies yields a clear and unique prediction about the outcome of the advertising game.     

Urban unemployment, informal sector and development policies

We analyze the effects of wage subsidy policies on unemployment and welfare in the model that is characterized by the existence of both open unemployment and the informal sector that producesfinal goods. Our main findings are as follows. Wage subsidies to the agricultural and informal sectors increase welfare and decrease urban unemployment. The effects of a wage subsidy to manufacturing sector on welfare and unemployment are conditional. We identify some sufficient conditions for the definite results and interpret them.     

Predicting capacity utilization: Federal Reserve vs time-series models

This study evaluates the Federal Reserve forecasts of manufacturing capacity utilization employing, as benchmarks, the forecasts from a univariate model which utilizes past information in capacity utilization, and from a bivariate model which utilizes past information in both capacity utilization and the federal funds rate. In addition to accurately predicting the directional change in capacity utilization, the Federal Reserve forecasts are “weakly” rational and generally superior to the bivariate forecasts. In light of another finding that monetary policy is non-neutral, we argue the Federal Reserve forecasts of capacity utilization have positively contributed to the Fed’s success in maintaining a low inflationary environment.

The effect of changes in ownership structure on performance: Evidence from the thrift industry

Restrictions on stock ownership may harm a company's performance, because restrictions prevent owners from choosing an optimal structure. We examine the stock-price performance and ownership structure of a sample of thrift institutions that converted from mutual to stock ownership. We find that after conversion and the expiration of ownership-structure restrictions, firm performance improves significantly, and the portions of the firm owned by managers and the firm's employee stock ownership plan increase. Changes in performance are positively associated with changes in ownership by managers, but negatively associated with changes in ownership by employee stock ownership plans.     

Imperfect Labor Mobility and Unemployment in LDCs: Reply

In a recent paper (Parai and Beladi 1997; PB hereafter), we have analyzed the implications of growth and trade policies for a small open economy facing imperfect labor mobility and unemployment of the Harris-Todaro variety. We have used the Casas (1984) specification of the labor immobility phenomenon for a Harris-Todaro type economy, and have shown that most of the results in Harris-Todaro framework remain unaltered even under imperfect labor mobility, provided that the elasticity of labor mobility parameter exceeds a critical minimum value. On the optimal tariff issue, Gilbert and Mikic (1997; GM hereafter) find our results counterconventional. In GM's view, the nonconventional result in PB is due to our simplification of the labor mobility specification given by Casas. In this note, we offer our response to GM's comments.
