The most striking feature of the current economic situation in Spain is the huge unemployment rate, above 25 percent. From an orthodox perspective, we suggest that this unemployment is the result of a highly inflexible labor market, which needs to be reformed by introducing flexibility measures. The paper argues, however, that labor market reforms introduced since the early 1980s, allowing an excessive use of temporary employment contracts, have had perverse effects on the Spanish economy. They have affected negatively not only aggregate demand and supply, but also income distribution. The emergence of these market reforms helps explain the current rate of unemployment as well as the deep impact of the global financial crisis on overall Spanish economic activity.  相似文献

This paper uses a stratified random sample of private sector employees to estimate wage equations for both the male labour market as a whole and six ‘segments’ of the labour market, segement which are defined with respect to the industry and size characteristics of the employing establishmen. Highly conventional results are obtained when wage equations are estimated for the male labour market as a whole, or within two segements, comprising almost half the survey population. However, one can reject conclusively the hypothesis that the same estimating equation is appropriate for modelling wage determination in all segments and if a ‘human capital’ (HK) model is, within segements, tested against more appropriate alternative hypotheses for wage determination using the Davidson and Mackinnon (1981) methodology for the testing of non-nested hypotheses, the conclusion is that one should reject the HK specification and not reject the alternative.

It is therefore argued that the disaggregation of labour market data reveals differences in the wage determination process that are not consistent with the view that labour markets are ‘dualistic’ but are consistent with the view that are segmented.  相似文献

A semi-nested test procedure is developed for choosing the numeraire for a normalized quadratic profit function when too few observations exist for nested hypothesis testing and when too many alternatives exis for conventional non-nested testing. Sensitivity of empirical results to choice of numeraire price is examined using agricultural data for the US and ten multistate regions. Few test conclusions vary by numeraire but own price input demand elasticities differ greatly.  相似文献

Recent empirical studies concerning purchasing power parity (PPP), using the concept of cointegraton, have tested the null hypothesis of the absence orthe presence of PPP. The disadvantage of using either of these approaches is that the conclusion is ambiguous when not rejecting the null: the result could be due to either the null hypothesis being true or by the low power of the test and lack of information in the data. Therefore, there is substantial information to be gained by applying both approaches within the same study. This study uses the ordinary DF test with PPP as the alternative hypothesis and a recently suggested test by Kwiatkowski et al. (1992) with PPP as the null. The tests are applied to four major industrial countries real exchange rates, each split into four different samples, including fixed as well as flexible exchange rate regimes. The absence of PPP cannot be rejected while the presence can be rejected.  相似文献

The BRICs nations (Brazil, Russia, India and China) have a strong relative economic growth pattern in the world among economic powers. The allure of globalization has made the analysis and assessment of national critical component of international portfolio management in recent years. We construct the model from comparing the relative SD of stock return whereby higher SDs are generally associated with more risk. This relative SD forms a principle component in the change of the weights on the international portfolio choice. The result shows that event jump risk not only makes the investor's allocation more conservative overall, but also it can be compensated on BRICs event risk.  相似文献

Since Vietnam, Lao People's Democratic Republic (PDR), Myanmar, and Cambodia joined the Association of Southeast Asian Nations (ASEAN) in the 1990s, concerns have been raised over a Development Divide. The real division is between ASEAN members participating in the integrated East Asian economy and those that do not. The older ASEAN members have become more efficient traders, and Cambodia, Laos, Myanmar, and Vietnam must reform faster if they are to catch up. Cambodia, Lao PDR, and Myanmar are not meeting the challenge, but Vietnam may be leaving the laggards, and the Philippines is lagging the leaders. The challenge is how to avoid a two‐tier ASEAN with fast‐growing modern economies coexisting besides inward‐looking poor countries.  相似文献

Good estimates place ‘hard core’ smoking rates in the United States at approximately 25%, with little change over the decade of the 1990s. This paper examines the possibilities of ‘harm reduction’ with the use of smokeless tobacco. Specifically, using an econometric model we seek to determine whether an increase in the use of smokeless tobacco would lead to reduced smoking rates in the United States. Applying our model to the NHANES III (National Health and Nutrition Examination Survey) we find that the use of smokeless tobacco by an average U.S. male smoker would increase the average probability of smoke cessation by over 10%. Approximately 3 million additional ‘quits’ would result for 26 million smokers. Our study permits an examination of cessation by age groups and we find that males who use smokeless tobacco between 16 and 65 have a 10–14% probability of quitting but that the probability falls beyond age 66. Important implications for life extension and health costs would attend these results with, under conservative assumptions, life years saved approximating 2.16 million and health care cost-savings of about $3 billion per year.  相似文献

The relationship between sources of income and demand decisions by the household is examined here with an eye toward the ramifications on consumption tax bases. Income sources may be important when households attach psychic and transaction costs to individual purchases or when sources are assigned via a mental accounting process. In either case, general and specific sales tax bases may be affected by changes in income composition. Empirical results indicate two important findings. First, tax exemptions can introduce significant income source effects for a general consumption tax base. Second, the importance of differential tax rates for gasoline and food-at-home strongly depends on the mix of labour, capital, retirement and non-retirement transfer pay.  相似文献
