The article highlights and explains the neglect of the activity of work in much of the mainstream economics literature. The neglect of work is seen to have denied space for mainstream economists to engage with the full range of possibilities for progress in human well‐being. The article also considers perspectives on work from within heterodox or non‐mainstream economics and argues that these perspectives provide a superior foundation for the theorization of work. 相似文献

We study the term structure of Brazilian sovereign bond yield spreads and their links with the domestic economy using a macro‐finance framework. Our model allows Brazilian macroeconomic variables as well as a latent country risk factor to affect sovereign spreads. We find that although the Brazilian sovereign yield spreads are dominated by the risk factor during the high default risk periods of 1999 and 2002, the effects of macro variables are significant during the rest of the estimation period. In addition, the volatility level of the macroeconomic system is driven by the country risk factor. 相似文献

Bloomfield and Hales (2002) find strong evidence that experimental market subjects are influenced by trends and patterns in a manner supportive of the shifting regimes model of Barberis, Shleifer, and Vishny (1998) . We subject the model to further empirical scrutiny using the football wagering market as our price laboratory. Sports betting markets have several advantages over traditional capital markets as an empirical setting, and commonalities with traditional markets allow for useful insights. We find scant evidence that investors behave in accordance with the model. 相似文献

Using an overlapping generations model with skill uncertainty and private savings, we quantify the gains of age‐dependent labor income taxation. The total steady‐state welfare gain of switching from age‐independent to age‐dependent nonlinear taxation varies between 2.4% and 4% of GDP. Part of the gain descends from relaxing incentive–compatibility constraints and part is due to capital‐accumulation effects. The welfare gain is of about the same magnitude as that which can be achieved by moving from linear to nonlinear income taxation. Finally, the welfare loss from tax‐exempting interest income is negligible under an optimal age‐dependent labor income tax. 相似文献

This paper generalizes the standard homoscedastic macro-finance model by allowing for stochastic volatility, using the \"square root\" specification of the mainstream finance literature. Empirically, this specification dominates the standard model because it is consistent with the square root volatility found in macroeconomic time series. Thus it establishes an important connection between the stochastic volatility of the mainstream finance model and macro-economic volatility of the Okun–Friedman type. This research opens the way to a richer specification of both macro-economic and term structure models, incorporating the best features of both macro-finance and mainstream finance models. 相似文献
