This paper assesses to what extent differences in the characteristics of individuals (micro‐level perspective) and country‐specific factors (macro‐level perspective) can explain country differences with respect to material deprivation levels. Thus, our work aims to simultaneously consider the macro dimension and the predominantly individually‐oriented study field of material deprivation using multilevel techniques. We make use of the European Union Statistics on Income and Living Conditions. Our results show that country‐specific factors seem to be much more relevant than individual effects in explaining country differences in material deprivation. We estimate that the introduction of country‐specific factors reduces the proportion of total variance due to between‐country differences in deprivation by 72.7 percent, while individual‐level variables reduce this proportion by only 9.4 percent. We also show, through interaction variables, that the effect of sociodemographic characteristics can be shaped by institutional and structural factors, especially by the level of GDP. 相似文献

Regional, national, and spatially explicit scenarios of demographic and economic change based on SRES 总被引:4,自引:0,他引:4
We report here spatially explicit scenario interpretations for population and economic activity (GDP) for the time period 1990 to 2100 based on three scenarios (A2, B1, and B2) from the IPCC Special Report on Emissions Scenarios (SRES). At the highest degree of spatial detail, the scenario indicators are calculated at a 0.5 by 0.5 degree resolution. All three scenarios follow the qualitative scenario characteristics, as outlined in the original SRES scenarios. Two scenarios (B1 and B2) also follow (with minor adjustments due to scenario improvements) the original SRES quantifications at the level of 4 and 11 world regions respectively. The quantification of the original SRES A2 scenario has been revised to reflect recent changing perceptions on the demographic outlook of world population growth. In this revised “high population growth” scenario, A2r world population reaches some 12 billion by 2100 (as opposed to some 15 billion in the original SRES A2 scenario) and is characterized by a “delayed fertility transition” that is also mirrored in a delayed (economic) development catch-up, resulting in an initially stagnating and subsequently only very slow reduction in income disparities. The spatially explicit scenario interpretation proceeds via two steps. Through a combination of decomposition and optimization methods, world regional scenario results are first disaggregated to the level of 185 countries. In a subsequent second step, national results are further disaggregated to a grid cell level, taking urbanization and regional (rural–urban) income disparities explicitly into account. A distinguishing feature of the spatially explicit scenario results reported here is that both methodologies, as well as numerical assumptions underlying the “downscaling” exercise, are scenario-dependent, leading to distinctly different spatial patterns of population and economic activities across the three scenarios examined. 相似文献

We compare models of Occupational Safety and Health Administration(OSHA) and Environmental Protection Agency (EPA) enforcementand compliance for steel plants during the 1980s. We find thatOSHA and EPA respond similarly to plant-level compliance andmeasures of hazardousness, but differently to firm-level complianceand risks of plant closing, and we relate the differences tothe agencies' differing organizational structures. Plant-levelcompliance is affected by enforcement pressure, compliance costs,and the firm's overall compliance behavior in similar ways forthe two regulatory areas, but environmental compliance was alsosensitive to plant size and risk of closing. Finally, we findthat the likelihood that a plant was in compliance with oneagency seemed at most weakly related to whether it was in compliancewith the other, but that plants likely to receive enforcementattention from one agency were also more likely to receive enforcementattention from the other agency. 相似文献

The productivity bias hypothesis states that a relatively more productive country should experience a real appreciation of its currency. Most studies in the literature that have tested the hypothesis have employed cross‐sectional data. Only a few studies have used time‐series data and they have tested the hypothesis for only a small number of countries. In this paper the authors test the hypothesis by using time‐series data over the 1960–90 period for a sample of 44 countries and with a relatively new method of cointegration known as the ARDL approach. For most countries there is strong evidence supporting the hypothesis. 相似文献

The advent of the Great Recession and the widespread adoption of fiscal austerity policies have heightened concern about inequality and its effects. We examine how the distribution of income in Ireland—a country which experienced one of the most severe economic contractions—has evolved over the years 2008 to 2013. Standard cross‐sectional analysis of the income distribution shows broad stability in the Gini coefficient and in decile shares, with one main exception: the share of the bottom decile fell sharply, with the largest fall in average incomes being for that group. Longitudinal analysis shows that the falls in the average income for the bottom decile were not due to decreasing income for those remaining in the bottom decile, but to falls in income from those initially located in higher deciles. The extent of redistribution through taxes and transfers increased strongly, as measured by the Reynolds‐Smolensky index, which rose from 0.20 before the onset of the crisis to 0.27 in 2013. Analysis indicates that about three‐quarters of this increased redistribution is due to automatic stabilisers and one‐quarter to discretionary policy changes. 相似文献

Scholars in economics and political science argue that one major function of government is to overcome coordination failure in economic development, especially during times of rapid environmental changes. But, how and through what means does the state coordinate firms to follow the changing directions of its economic objectives? This paper focuses on the case of a government-controlled business association, namely the All-China Federation of Industry and Commerce (ACFIC), and shows that the ACFIC may be serving, at least partially, as a means of avoiding the kind of coordination failures that are often associated with policy reform programs in authoritarian regimes like China when the government deems it necessary to radically and suddenly change its policy objectives. It does so by comparing the activities of firms that are members of ACFIC with non-members before and after the world financial crisis of 2008–09 which induced a significant change in government objectives. Before that crisis when priority in government objectives was “outward” (to stave off balance of payments crises that had befallen many other developing countries), ACFIC member firms were able to engage in exports and foreign investment to a greater extent than non-member firms, and even than those whose owners are members of the Congresses or Chinese Communist Party. After viewing the crises in international markets, and government objectives had turned more “inward”, ACFIC members were more likely to focus on domestic sales and investments. 相似文献

This paper explores the role of inward foreign direct investment (FDI) as a determinant of domestic firms’ wages, namely wage spillovers. We first construct a theoretical model to demonstrate that the presence of FDI firms affects domestic firms’ expected average wages via productivity spillovers and a cut-off capability. We then estimate FDI-induced wage spillovers by employing IV-GMM estimator with a five-year panel dataset of a growing service industry in Vietnam. Despite FDI firms on average pay 2.25 times that of domestic firms, they put a downward pressure on domestic firms’ wages. A one percent increase in FDI presence causes domestic firms to cut average wages by 2.03 percent. The estimations also find that firm-specific features are attributable to significant differences in their wages as well as FDI-linked wage spillovers. 相似文献

The propensity of the forecasts of sell-side financial analysts to converge (or diverge) is a function of their exogenous and endogenous selective attention and overconfidence. When returns are negative, the endogenous form of selective attention—a static measure of analysts’ goal-driven attention at a particular point in time—has a positive association with convergence. The exogenous form of selective attention—a relatively involuntary dynamic process of exogenous attentional shift driven by external changes in the market over time—is associated with a tendency for forecasts to diverge. 相似文献

Scenarios are claimed to support strategic decision makers. They are especially effective in dealing with uncertainties. This paper addresses some drawbacks of the conventional scenario method, which is especially directed at handling these uncertainties, and indicates possible avenues for methodological adaptations. We take the approach, which rests in the Shell tradition, as exemplary for our discussion on the mainstream scenario methodology. This approach has some limitations when it comes to dealing with simultaneous trends and countertrends, and trends or clusters of trends that are not thought of beforehand, especially the methodological requirements of causality and consistency, which might be limiting factors in this respect. This paper indicates alternative ways for scenario construction. It discusses the use of either recombinant scenarios, context scenarios, or inconsistent scenarios and/or combinations of these scenarios. These options explicitly incorporate the notion of ‘paradoxical trend’ as the codriver of future developments into the methodology. 相似文献

The substantively rational value of the games studied in this paper does not help predict subject performance in the experiment at all. An accurate model must account for the cognitive ability of the people playing the game. This paper investigates whether the variation in measured rationality bounds is correlated with the probability of winning when playing against another person in games that exceed both players’ estimated rationality bound. Does seeing deeper into a game matter when neither player can see to the end of the game? Subjects with higher measured bounds win 63 percent of the time and the larger the difference the more frequently they win. 相似文献
