Regional corn yield models incorporating stochastic trends, prices and weather variables are estimated. Hypothesis tests suggest yield variability has increased because of an increase in error variance and an increase in weather-related effects. Decomposition of the error variance shows much of its increase is due to an increased correlaion between regional yields. 相似文献

To solve the problem of illegal landings this article proposes a new tax mechanism based on the regulator's own aggregate catch estimates and ex ante self-reports of planned catch by fishermen. We show that the mechanism avoids illegal landings while ensuring (nearly) optimal exploitation and generating (nearly) correct entry and exit incentives. Finally we simulate the mechanism for the Danish cod fishery in Kattegat to obtain a rough indicator of the size of the tax. It turns out that the average tax payment as a percentage of profit is surprisingly low. 相似文献

We analyze the concentration of foreign direct investment (FDI) in India at the district level, based on project-specific location choices since the reform program in the early 1990s. The decomposition property of the Theil index allows us to trace changes over time in the overall concentration of FDI to changes in concentration between and within subgroups of districts. We also differentiate between major types and sources of FDI. We find that FDI concentrated in a persistently decreasing number of districts. Concentration across those districts that received at least one FDI project within a given time interval also increased, but this increase leveled off in the more recent past. These trends hold for essentially all types and sources of FDI, while the average level of concentration varies considerably between these types and sources. 相似文献

We develop a model of tax evasion based on the Ising model. We augment the model using an appropriate enforcement mechanism
that may allow policy makers to curb tax evasion. With a certain probability tax evaders are subject to an audit. If they
get caught they behave honestly for a certain number of periods. Simulating the model for a range of parameter combinations,
we show that tax evasion may be controlled effectively by using punishment as an enforcement mechanism. 相似文献

We examine how different methods of reparations payments to African‐Americans affect both the black and nonblack populations of the United States using the framework of the transfer‐problem from international trade theory as a theoretical foundation. We find that reparations payments that provide incentives for blacks to use the payment toward purchases of goods and services produced by nonblacks might expand the income gap. Also a reparations payment in the absence of productive capacity owned by blacks is found to have no final positive impact on black income. These results indicate that a reparations payment strategy must be carefully and cautiously conceived in order to achieve the desired effects. 相似文献

This paper examines the incentive effects of the soft budget constraint on the investment behavior of firms in general and on the investment-cash flow sensitivity in particular. To this end, we develop a simple model of moral hazard that takes the soft budget constraint into account. Within this moral hazard environment, we show that investment is positively related to the amount of internal funds. We further show that the presence of the soft budget constraint deteriorates the moral hazard problem, thereby making the investment level less sensitive to the amount of internal funds. This is the case irrespective of whether the soft budget constraint renders the firm more or less liquidity constrained. To test the model's empirical implications, we employ data of China's listed companies for the period from 1997 to 2003. We use the share of state ownership as a proxy for the severity of the soft budget constraint. We find strong evidence that firms with larger shares of state ownership exhibit lower investment-cash flow sensitivities than firms with smaller shares of state ownership. 相似文献

If consumers wholly or partially control a firm with market power they will charge less than the profit maximizing price.
Starting at the usual monopoly price, a small price reduction will have a second order effect on profits but a first order
effect on consumer surplus. Despite this desirable static result, it has been argued that cooperatives are vulnerable to take-over
by outsiders who will run them as for-profit businesses. This paper studies takeovers of cooperatives. We argue that there
will not be excessive takeovers of cooperatives due to the Grossman-Hart problem of free riding during takeovers. 相似文献

Performance targets are commonly used in the public sector, despite their well known problems when organisations have multiple objectives and performance is difficult to measure. It is possible that such targets may work where there is considerable consensus that performance needs to be improved. We investigate this possibility by examining the response of the English National Health Service to high profile waiting time targets. We exploit a natural policy experiment between two countries of the UK (England and Scotland) to establish the global effectiveness of the targets. We then use a within-England hospital analysis to confirm that responses vary by treatment intensity and to control for differences in resources which may accompany targets. We find that targets met their goals of reducing waiting times without diverting activity from other less well monitored aspects of health care and without decreasing patient health on exit from hospital. 相似文献
