Harnessing changes in funding for a voucher program that subsidizes consumers' use of child care services at private providers, this study quantifies effects on local markets' service capacity and prices. We also estimate how increased funding effects provider entry rate, exit rate, and highly...

The interrelationship between economic growth, efficient use of natural resources, and sustainability has been of great interest to economists, researchers and policy makers. Knowledge of actual causality direction between sustainability, efficiency and growth has important implications for...

This paper tests empirically the theoretical prediction that the country premium paid by emerging economies on sovereign debt increases with the amount of debt up to a certain critical level, above which the supply of foreign funds becomes fixed. The results confirm this theoretical prediction....

China has experienced dramatic economic transformation and is facing the challenge of ensuring steady agricultural growth. This study examines the crop sector by estimating the supply response for major crops in Henan province from 1998 to 2007. We use a Nerlovian adjustment adaptive expectation...

This report reviews research on the effectiveness of acreage reduction programs and describes the methodology developed for the Static World Policy Simulation (SWOPSIM) modeling framework to capture the effect of removing these programs. It also analyzes the results of several sensitivity tests...

Supply response to price changes is likely to increase with the increasing liberalization of the agricultural sector. Past studies revealed weak supply response for Indian agriculture. There are no recent reliable estimates to see if the response has improved after the economic reforms...

Optimum commodity taxation theory asks how to raise a given amount of tax revenue while minimizing distortions. We reexamine Ramsey's inverse elasticity rule in presence of Hotelling-type non-renewable natural resources. Under standard assumptions borrowed from the...

Trade elasticities are often needed in applied country work for various purposes and this paper describes a method for estimating import demand and export supply elasticities withoutusing econometrics. The paper reports empirical estimates of these elasticities for a large number of low, middle,...

We present evidence on one facet of energy security in OECD economies - the extent of diversification in sources of oil and natural gas supplies. Viewed from the perspective of the energy-importing countries as a whole, there has not been much change in diversification in oil supplies over the...
