Decision-making under uncertainty for capital budgeting and hiring

Most business decisions are not merely risky but are subject to uncertainty. Different individuals estimate different measures of merit. It is shown that the traditional procedure of ranking the alternatives by their estimated measure of merit and then choosing the highest ranked alternative frequently gives the wrong answer even where the estimates are unbiased. The argument will be made using a simple decision tree. The effect will be shown to be especially serious where there is competition, direct or indirect, between the alternatives.     

The Role of Absolute Continuity in “Merging of Opinions” and “Rational Learning”

D. Blackwell and L. Dubins (1962, Ann. Math. Statist.38, 882–886) showed that opinions merge when priors are absolutely continuous. E. Kalai and E. Lehrer (1993, Econometrica61, 1019–1045) use this result to show that players in a repeated game eventually play like a Nash equilibrium. We provide an alternative proof of merging of opinions that clarifies the role of absolute continuity while casting doubt on the relevance of the result. Persistent disagreement, the opposite of merging, allows the construction of a sequence of mutually favorable “bets.” By a law of large numbers, both agents are certain they will win these bets on average. This certain disagreement violates absolute continuity. Journal of Economic Literature Classification Numbers: C11, C69, C72, D83.     

Crowding-out and crowding-in effects of the components of government expenditure

This article examines the effects of disaggregated government expenditure on investment using fixed- and random-effect methods. Using the government budget constraint, the analysis explores the effects of tax- and debt-financed expenditure for the full sample, and for subsamples of developed and developing countries. In general, tax-financed government expenditure crowds out more investment than debt-financed expenditure. Expenditure on social security and welfare reduces investment in all samples while expenditure on transport and communication induces private investment in developing countries.     

The First Wave of Mass Privatization in Bulgaria and its Immediate Aftermath

In January 1995, a Socialist government came to power in Bulgaria and initiated a mass privatization programme. In the first wave of this programme, which was completed in June 1997, about one-fourth of Bulgaria's state-owned enterprises were partially privatized through the programme. Patterned after the Czech mass privatization programme, an important outcome of the Bulgarian programme is that investment funds have become important agents in the private sector of the economy. It is too early to determine whether enterprise restructuring will now occur, but initial market signals suggest that Bulgaria may soon suffer from many problems that now confront the Czech economy unless new corporate laws supporting ownership rights and better capital market regulations are enacted.     

CALCULATING A PRICE INDEX FOR FAMILIES WITH CHILDREN: IMPLICATIONS FOR MEASURING TRENDS IN CHILD POVERTY RATES

This paper investigates the effects of varying consumption patterns for families with and without children on measured trends in child poverty. We first use data from consumer expenditure surveys to calculate price indices by family type. We next examine the effect of using these group-specific price indices on measured trends in child poverty. Although we find that, all else equal, children increase the cost of living, our calculations indicate that on average families with children experienced relatively lower inflation rates than families without children during the 1968 to 1987 period. While this result suggests that estimates of child poverty rates calculated using an average price index may have over-stated secular increases in child poverty, we find that child poverty rates calculated using a price index specific lo families with children are not substantively different from those calculated using an average index for all families.
