TAXES AND EMPLOYMENT SUBSIDIES IN OPTIMAL REDISTRIBUTION PROGRAMS

This paper explores how to optimally set tax and transfers when taxation authorities : (1) are uninformed about individuals’ value of time in both market and non-market activities and (2) can observe both market-income and time allocated to market employment. In contrast to much of the optimal income taxation literature, we show that optimal redistribution in this environment involves distorting market employment upwards for low net-income individuals through phased-out wage-contingent employment subsidies, and distorting employment downward for high net-income individuals through positive and increasing marginal income tax rate. We also show that workfare may also be used as part of an optimal redistribution program.Taxation ; Redistribution ; Wage Subsidies Screening

A gains from trade perspective on macroeconomic fluctuations

Business cycles reflect changes over time in the amount of trade between individuals. In this paper we show that incorporating explicitly intra-temporal gains from trade between individuals into a macroeconomic model can provide new insight into the potential mechanisms driving economic fluctuations as well as modify key policy implications. We first show how a gains from trade approach can easily explain why changes in perceptions about the future (including news about the future and risk shocks) can cause booms and bust. We then turn to fiscal policy, and discuss under what conditions fiscal multipliers can be observed. While much of our analysis is conducted in a flexible price environment, we also present implications of our model for a sticky price environments, as it allows to understand stable-inflation boom-bust cycles. The source of the explicit gains from trade in our setup derives from simply assuming that in the short run workers are not perfect mobile across all sectors of the economy. We provide evidence from the PSID in support of this modeling assumption. --business cycle,investment,heterogeneous agents

Managerial Skill Acquisition and the Theory of Economic Development

Micro level studies in developing countries suggest managerial skills play a key role in the adoption of modern technologies. The human resources literature suggests that managerial skills are difficult to codify and learn formally, but instead tend to be learned on the job. In this paper we present a model of the interactive process between on-the-job managerial skill acquisition and the adoption of modern technology. The environment considered is one where all learning possibilities are internalized in the market, and where managers are complementary inputs to non-managerial workers. The paper illustrates why some countries may adopt modern technologies while others stay backwards. The paper also explains why managers may not want to migrate from rich countries to poor countries as would be needed to generate income convergence.

Stock Prices, News and Economic Fluctuations

In this paper we show that the joint behavior of stock prices and TFP favors a view of business cycles driven largely by a shock that does not affect productivity in the short run -- and therefore does not look like a standard technology shock -- but affects productivity with substantial delay -- and therefore does not look like a monetary shock. One structural interpretation we suggest for this shock is that it represents news about future technological opportunities which is first captured in stock prices. We show that this shock causes a boom in consumption, investment and hours worked that precede productivity growth by a few years. Moreover, we show that this shock explains about 50\% of business cycle fluctuations.

Globalization, Returns to Accumulationa and the World Distribution of Output

This paper examines the extent to which the process of globalization can explain the observed widening in the cross--country distribution of output--per--worker. In particular examine whether the opening up of trade in a Hecksher--Ohlin type model of trade can explain the observed changes. On the theoretical front the model highlights that, when the labor market is subject to a holdup problem, then the opening up of trade can cause an increase in the dispersion of income across countries similar to that observed in the data due to the emergence of a discrepancy between the private and social returns to capital accumulation that favors capital abundant countries. On the empirical front, we document the relevance of the model by examining whether growth patterns, decomposition exercises and specialization patterns support the model's predictions. Overall we find that over 50% of the recently observed increase in income dispersion across countries can be accounted for by the mechanism exemplified by the model.
