A DISEQUILIBRIUM INTERPRETATION OF KALDOR'S TECHNICAL PROGRESS FUNCTION*

This note examines the nature of underlying production function to Kaldor's technical progress function. It has been found that in the context of disequilibrium between planned savings and investment the history of capital accumulation becomes crucial.     

Optimum allocation in stratified sampling with replacement

In a stratified sample, when sampling is done with replacement in each stratum a better estimate of the population mean can be achieved by considering the distinct units only. An explicit expression for the variance for the mean, of a stratified sample based on the distinct units only, is obtained. Then the optimum allocation for the different stratum are obtained by minimizing this variance subject to (i) total sample size being fixed, or (ii) the expected number of distinct units being fixed. Neyman’s solutions are obtained as special cases. The solutions finally arrived at are algebraically complex, hence, numerical methods are applied. In all examples, the variance of the estimates obtained by this method are smaller than the variances obtained by Neyman’s allocation.

DATA REVISION AND MARKET RESPONSE: THE CASE OF UNITED STATES TRADE BALANCE ANNOUNCEMENTS†

ABSTRACT In this paper we study economic news, as reflected in the announcements of the United States trade balance by the Commerce department, to illustrate the importance of revised data versus preliminary data to economic agents. A new methodology has been developed here to study how agents in the exchange market respond to these monthly trade balance announcements and consequently, move the dollar's exchange rate. In contrast to previous studies where agent reactions to only preliminary trade figures were analyzed, this method is applied to examine market reactions to the preliminary and revised trade balance figures.     

Durability Versus Concentration as an Explanation for Price Inflexibility

We document the extent of price rigidity across United States manufacturing industries in the 1980s and early 1990s and compare rigidity across different phases of the business cycle. We measure price rigidity in three ways – each under four different sets of assumptions. We take an approach that relies on disaggregated data; we look at price patterns for over 4000 individual manufactured commodities. Both durability and seller concentration are found to be important factors explaining differences in price rigidity across industrial product classes. Using our data, we replicate the regression results found in Carlton (1986) that were based on actual transaction prices from the 1960s.     

Efficiency Considerations in the Additive Hazards Model with Current Status Data

For current status data, L IN , O AKES and Y ing (1998) proposed a procedure for estimation of the regression parameters in the additive hazards model that makes clever use of martingale theory. However, one of the outstanding problems posed in the paper was the issue of efficient estimation, as their estimators do not attain the semiparametric information bound. In this paper, we explore this issue and provide a characterization of the NPMLE. We conduct efficiency comparisons between the NPMLE and the procedure of L IN et al . (1998) analytically and numerically through analysis of a dataset from a tumorigenicity experiment.     

Investor Protection,Investment Efficiency and Value: The Case of Cross‐Listed Firms

We examine the impact of improved investor protection due to cross‐listing on foreign firms’ investment decisions and firm value. While we find that cross‐listing increases firms’ capital expenditures and mergers and acquisitions activities, cross‐listed firms also invest more in research and development, make better acquisition decisions, and have higher profitability compared to non‐cross‐listed firms. Moreover, cross‐listing is associated with better cash utilization by foreign firms for investments. These improvements in investments and cash utilization are more pronounced for firms cross‐listed on US exchanges and for firms from countries with weak investor protection laws.     

Junk bonds,life insurer insolvency,and stock market reactions: The case of first executive corporation

The First Executive Corporation was the largest failure in the history of the life insurance industry. The company was one of the most aggressive purchasers of junk bonds through the 1980s and was the first of several large failures in the staid life insurance industry. In this article, we examine the effect of First Executive's failure on the value of companies in the life insurance industry. We find that the price of other life insurance companies' stock is negatively affected by the earnings announcement that preceded First Executive's failure. The magnitude of an individual company's reaction to First Executive's loss varies according to the proportion of the company's assets invested in junk bonds, the proportion of the company's assests invested in real estate, and the financial strength of the company as measured by A.M. Best's rating.
