This study analyzes the testing of cross-equation restrictions within a set of regression equations. Through Monte Carlo experiments we examine the actual size of various asymptotic procedures for testing the poolability hypothesis, i.e., equal slope vectors across individual equations. Regression models with both lagged dependent variable regressors and nonspherical disturbances are considered. In these models we find that the performance in finite samples of classical asymptotic test procedures using critical values from either or 2 approximations is often rather poor. However, employing the original test statistics with bootstrapped critical values leads to much more accurate inference in finite samples. In an empirical analysis of panel data on GDP growth and unemployment rates in OECD countries it is shown that classical asymptotic tests and bootstrap procedures may lead to conflicting test outcomes.

The two-country monetary model is extended to include a consumption externality with habit persistence. The model is simulated using the artificial economy methodology. The ‘puzzles’ in the forward market are re-examined. The model is able to account for: (a) the low volatility of the forward discount; (b) the higher volatility of expected forward speculative profit; (c) the even higher volatility of the spot return; (d) the persistence in the forward discount; (e) the martingale behavior of spot exchange rates; and (f) the negative covariance between the expected spot return and expected forward speculative profit. It is unable to account for the forward market bias because the volatility of the expected spot return is too large relative to the volatility of the expected forward speculative profit. 相似文献

There is an ongoing debate about face masks being made compulsory in public spaces to contain COVID-19. A key concern is that such policies could undermine efforts to maintain social distancing and reduce mobility. We provide first evidence on the impact of compulsory face mask policies on community mobility. We exploit the staggered implementation of policies by German states during the first wave of the pandemic and measure mobility using geo-located smartphone data. We find that compulsory face mask policies led to a short-term reduction in community mobility, with no significant medium-term effects. We can rule out even small increases in mobility. 相似文献

Grounded in the transactional stress-coping theory and the Tallis and Eysenck (1994) model of nonpathological worry, the present study sought to advance the conceptual and empirical understanding of financial worry (FW). We positioned objective financial stressors (OFS), subjective financial stressors (SFS), and coping resources as key variables in understanding the determinants of financial worry (FW). The cross-sectional data consisted of responses from a representative sample of 19,385 adults, aged 18 and older, drawn from a large U.S. survey. Hierarchical linear regression results revealed that OFS, SFS, household income, and financial capability (FC) are all key determinants of FW. Furthermore, the results revealed adverse effects of OFS and SFS on FW. These effects were moderated by household income, FC, age, and gender. Implications for future research, employers, practitioners, and policymakers are discussed. 相似文献
