This article aims to establish the changes that occurred in the institutional structures governing trade policy in South Africa during the period 1990–1998. It also examines the forces that influenced the application of tariff policy by the major tariff-setting bodies by applying various theories of endogenous protection to their decisions. Using firm-level data on applications made to the Board on Tariffs and Trade, the study finds that when estimating a probit model, employment considerations rather than capital invested influenced the board's decisions to grant protection. In addition, the board is found to have granted protection even in the face of tariff lines having been bound under the Uruguay Round. The article argues that this should not be interpreted as a reversal of the trade liberalization but rather as an attempt by the board to cushion firms from the acceleration in the tariff rationalization process that occurred after the GATT offer. Finally, it is suggested that the board's response to changes in import penetration ratios between industries that were considered organized provides prima facie evidence of the superior lobbying ability of such industries. 相似文献

Attitudes towards risk are measured for households in Northern Zambia using an experimental gambling approach with real payoffs that at maximum were equal to 30% of average total annual income per capita. The results of the experiment show decreasing absolute risk aversion and increasing partial risk aversion. Determinants of risk aversion are investigated using random effects interval regression model exploiting the panel data structure of the repeated experiments. Wealth indicator variables are found to be significant, and partial relative risk aversion decreases as wealth increases. Females are found to be more risk averse than males. 相似文献

This article examines factors related to a livestock rental market in western Nepal and assesses whether this market is associated with caste differentiation and land rental market participation. Theoretical models for asset‐rich (i.e., high‐caste) households, rich in land and livestock, and asset‐poor (i.e., low‐caste families) households are presented to provide logical explanations for the existence of a livestock rental market and the synergy between livestock and land rental markets participation. A combination of double hurdle models and bivariate‐ordered probit models were used to test the implications of the models. Consistent with the theoretical models, land‐ and livestock‐rich high‐caste households were more likely to rent out land and/or livestock, whereas land‐ and livestock‐poor and credit constrained low‐caste households were more likely to rent livestock and land from others. Participation in the two markets was positively correlated, indicating a synergistic relationship that may be due to production and transaction costs reducing benefits. Policies that can enhance the allocative efficiency of livestock and land rental markets can improve equity as well as efficiency of land use in Nepal. Provision of livestock credit to land‐poor low‐caste households is also crucially dependent on their access to more long‐term contracts for land. 相似文献

We track the level of economic well-being of the population of men who began receiving Social Security Disability Insurance
benefits in 1980–81 from the time just after they became beneficiaries (in 1982) to 1991. We present measures of the economic
well-being of disabled individuals and their nondisabled peers as indicators of the relative economic position of these two
groups. These measures also provide an intertemporal comparison of well-being and hardship as disabled persons and their nondisabled
peers age and retire. We first show several economic well-being indicators for new male recipients of disability benefits
in 1982 and 1991. We then compare their economic position to that of a matched group of nondisabled males with sufficient work histories to have been disability-insured. Because labor market changes over this decade
have led to a relative deterioration in the position of younger and less-educated workers, we compare men with disabilities
to those without disabilities and distinguish different age and educational levels within the groups. We conclude by assessing
the antipoverty effectiveness of Social Security income support for both younger and older male SSDI recipients.

The non-accelerating wage rate of unemployment (NAWRU indicator), used by the OECD as a measure of structural unemployment, has risen for the four Nordic countries Denmark, Finland, Norway and Sweden. In this paper we present stable empirical wage equations for the same countries over the period 1964–1994, in sharp contrast to the increased NAWRU estimates. The instability of the NAWRU estimates is an artefact of a misspecified underlying wage equation, and not due to instability in wage setting itself.
