Do the presence and nature of entrepreneurship impact on national happiness, and are nations with happy citizens better for entrepreneurs to start new businesses? To provide tentative answers we survey the literature on entrepreneurship and subjective well-being and use various data sources to uncover the first evidence of the relationship between entrepreneurship and happiness at the country level. We find that opportunity-motivated entrepreneurship may contribute to a nation’s happiness but only to a certain point, at which the effects of happiness begin to decline. Moreover, our results suggest that a nation’s happiness affects early-stage opportunity-driven entrepreneurial activity. 相似文献

Pre‐committed consumption represents the portion of demand that is determined by non‐price and non‐income factors. This study uses quarterly data to estimate a Generalised Almost Ideal Demand System (GAIDS) to test for the existence of pre‐committed meat consumption in Australia. Two specifications are estimated to evaluate the impact of seasonal and time trend factors on pre‐committed demand. Evidence is found for the existence of pre‐committed chicken consumption when jointly estimated with seasonal and time trend factors. Results support improved demand modelling of Australian meat consumption using the GAIDS and provide insights into how Australian meat demand is affected by price, expenditures, pre‐committed consumption, seasonality, and trends. 相似文献

What information do individual investors use when making their financial decisions and how is it related to their stock market expectations, their confidence in these expectations, and the risk and return of their stock portfolios? I study these questions by combining survey data on the information usage among individual investors in Sweden with detailed registry data on their stock portfolios. I find that investors use filtered financial information (e.g. information packaged by a professional intermediary) more frequently than they use unfiltered financial information (e.g. information from annual reports and financial statements). Investors who frequently use filtered financial information are, however, more confident in their stock market expectations and take larger risks in their stock portfolios. Investors that instead use unfiltered financial information take lower portfolio risks and obtain higher portfolio returns. The findings in this paper thus suggest that investors can improve their financial decisions by using more unfiltered financial information rather than filtered financial information when they make their financial decisions. 相似文献

We present a dynamic, non‐scale general‐equilibrium model with female and male human capital where Schumpeterian R&D and human‐capital accumulation are the engines of growth and gender wage inequality. Gender wage inequality is encouraged by changes in relative supply and relative demand of both human‐capital types. Relative supply restricts the levels of employed human capital. Relative demand is affected by the technological‐knowledge bias, which is driven by the price channel and is affected by human‐capital accumulation. In particular, the female‐premium per unit of human capital and per worker increases when the observed discrimination against women decreases or is removed. 相似文献

This study explores tourists’ contribution to air pollution through an analysis of tropospheric ozone levels. Although the ozone layer in the upper atmosphere is beneficial, preventing damaging ultraviolet light from reaching the Earth's surface, ozone in the lower atmosphere, known as tropospheric ozone, can damage plant species, both natural materials and manufactured goods, and can damage lung tissues in humans. Additionally, ozone in the upper troposphere exerts a considerable impact on global warming. Using the case study of Mallorca (Spain) – an isolated, intensive tourist destination in the Mediterranean – a daily indicator of tourist numbers is used in order to capture direct and induced pressure on the environment. Models based on daily data are estimated using meteorological, daily tourist numbers and other significant variables, showing how rising tourism activity in Mallorca is associated with rising daily concentrations of tropospheric ozone, created by transport, air conditioning and other activities. The estimated models make different simulations possible, showing the consequences of increasing tourism numbers during different seasons. The concluding section shows the potential to develop the models used here for other destinations. 相似文献

We axiomatically characterize the Theil ordering of income inequality. In addition to the uncontroversial axioms of anonymity, homogeneity, replication invariance, strong directedness, and a standard continuity property, we appeal to both an independence and a decomposability axioms. These two axioms are ordinal implications of Theil decomposability, the central axiom in previous characterizations of the Theil index. To the best of our knowledge, the present is the first fully ordinal characterization of this index. 相似文献

In the standard models of North-South technological-knowledge diffusion, the larger the initial technological-knowledge gap between countries, the greater the Southern catching up. However, this result does not adjust well to Southern reality as a whole. The purpose of this paper is to demonstrate that the disparity between the theoretical outcome and the empirical findings can be reduced by considering that: (i) the South can only imitate Northern technological knowledge when it is sufficiently close to the Northern frontier; (ii) the advantage of the South's moderate backwardness, together with its imitation capacity, is a mechanism of catching up with the North; and (iii) the Southern catching-up specification can be country specific. In particular, we show that the behavior of the South's relative level of employed human capital affects Southern imitation capacity and depends on the catching-up specifications. 相似文献

There are many ways to measure productivity. The choice will depend on the suitability of each index to the main purpose the researcher has in mind. Whenever we are interested in 'competitiveness', the proper measure will be the inverse of the total labour embodied in one unit of final product; or, what amounts to the same, the labour employed in the vertically integrated sector corresponding to each final good. A weighted mean of these yields an index of aggregate productivity suitable for measuring social welfare. Another index of aggregate productivity (this one related to the profit rate and potential growth) coincides with the inverse of the maximum eigenvalue of the 'socio-technical matrix'. These indices are computed for the Spanish economy and compared with more conventional ones. 相似文献

The net asset values for Asian–country mutual funds in the US come from the underlying market's close a half–day earlier and create inefficiencies that improve returns 6 to 12 times in a pure sense. While these are mitigated because of loads, restrictions on trading and fair value pricing, informational biases exist in trading such funds. These can be exploited with a simple rule: If one plans to trade at all, then one should buy (sell) the fund after its own Asian–country index falls (rises). Basing NAVs on the underlying market's close after the NY market closes can eliminate this inefficiency. 相似文献
