The case of German reunification has been subject to extensive research on earnings inequality and labour market integration. However, little is known about the development of equality of opportunity (EOp) in East and West Germany after 1990. Using German micro data, we empirically analyse how circumstances beyond the sphere of individual control relate to inequality in East and West Germany. Our results show that EOp is larger in East than in West Germany. However, despite increasing income inequality, EOp remained surprisingly constant.  相似文献

The present study examines the relationship between corporate social responsibility (CSR) and firm value, and the effects of corporate governance code revisions on the relationship. We examine this relationship for: (i) a high‐income country, Japan; (ii) middle‐income countries China, Malaysia and Thailand; and (iii) low‐income countries India and Indonesia. We use the Heckman two‐stage sample selection bias approach for the empirical analysis. We find that Japanese stakeholder CSR and environmental CSR have a smaller positive effect on firm value compared to the middle‐income countries, but we do not find any statistically significant association for the low‐income countries. In addition, we find that only Japanese corporate governance code revisions significantly contribute to the positive relationship between CSR and firm value, which concurs with the new recommendations documented in the revised codes of corporate governance. The present study reveals that foreign major shareholders matter to the value creation of CSR in Japan and the middle‐income countries of China, Malaysia and Thailand.  相似文献

Facing the challenge of climate change, innovations that imply environmental benefits create business opportunities for entrepreneurs. This paper analyzes innovation capabilities of startups in Cleantech and how the innovation outcomes of those startups develop over time. Based on the Mannheim Foundation Panel and applying propensity score matching, a cohort of 567 Cleantech startups is analyzed and compared with a control cohort of non‐Cleantech startups. We find that startups in Cleantech have, on average, higher technological capabilities compared with all other startups. Our econometric evidence shows that Cleantech startups are more likely to combine existing technology in a novel way. Finally, we find that Cleantech startups develop more market novelties in subsequent years when compared with their control group peers.  相似文献

Social trust is linked to both public sector size and to economic growth, thereby helping to explain how some countries combine high taxes with high levels of economic growth. This paper examines if social trust insulates countries against the negative effects of public sector size on growth, documented in several studies. We note that the effect is theoretically ambiguous. In panel data from 66 countries across 40 years, we find no robust evidence of insulation effects: when excluding countries with uncertain trust scores, our results suggest that big government hurts growth also in high‐trust countries, and that the mechanism is by lowering private investments.

We examine the implications of limited consumer attention for the targeting decisions of competing firms. Limited attention alters the strategic role of information provision as firms may become incentivized to behave as mass advertisers, despite perfect targeting abilities. We analyze the consequences of limited attention for targeting, strategic pricing, market shares, attention competition between firms, and the value of marketing data to firms. Accounting for limited attention in an otherwise standard targeting framework can explain several recent key issues from the advertising industry, such as consumer-side information overload or the increased usage of ad blocking tools.  相似文献

I examine the determinants of both perceived inflation and unemployment in one single survey and include Big Five traits in the analysis. This is the first survey on this topic in Germany. My sample consists of 1771 students from different fields and levels. Using PhD students’ estimates as a reference, I create categories for underestimation and overestimation of both variables. Multinomial logit regressions show that females overestimate both variables. Education and news consumption reduce misestimation. A higher level of Neuroticism is related with a higher probability to overestimate unemployment. Overstating (understating) one indicator is associated with overstating (understating) the other.  相似文献

We compare the out-of-sample performance of monthly returns forecasts for two indices, namely the Dow Jones (DJ) and the Financial Times (FT) indices. A linear and a nonlinear artificial neural network (ANN) model are used to generate the out-of-sample competing forecasts for monthly returns. Stationary transformations of dividends and trading volume are considered as fundamental explanatory variables in the linear model and the input variables in the ANN model. The comparison of out-of-sample forecasts is done on the basis of forecast accuracy, using the Diebold and Mariano test [J. Bus. Econ. Stat. 13 (1995) 253.], and forecast encompassing, using the Clements and Hendry approach [J. Forecast. 5 (1998) 559.]. The results suggest that the out-of-sample ANN forecasts are significantly more accurate than linear forecasts of both indices. Furthermore, the ANN forecasts can explain the forecast errors of the linear model for both indices, while the linear model cannot explain the forecast errors of the ANN in either of the two indices. Overall, the results indicate that the inclusion of nonlinear terms in the relation between stock returns and fundamentals is important in out-of-sample forecasting. This conclusion is consistent with the view that the relation between stock returns and fundamentals is nonlinear.  相似文献

Ekzeme – eine h?ufig untersch?tzte Gefahr - Untersuchungen zeigen, dass die Lebensqualit?t durch berufsbedingte Hauterkrankungen genauso eingeschr?nkt wird wie durch einen Myokardinfarkt oder Schlaganfall. Das ist für Pflegende deshalb so bedeutsam, weil gerade in Pflegeberufen Kontakt zu potenziell Allergie ausl?senden Stoffen besteht.  相似文献

Existing research on product design has demonstrated the importance of aesthetics in generating favorable consumer responses. However, the literature has only recently begun to explore if and to what extent the impact of product design is influenced by brand strength. Whereas some research indicates that strong brands may benefit less strongly from aesthetically attractive designs, other research suggests that attractive designs are more persuasive when they are paired with a strong brand. In this research, these two competing predictions were tested through three studies with German car buyers. In Study 1, participants were exposed to a fictitious car that was paired with a randomly chosen brand name. In Study 2, participants were presented with a set of existing cars and were asked to choose one. Both studies yield converging evidence and show that product design and brands interact in a positive fashion, suggesting that attractive designs exert a greater influence on consumers’ decision processes when they are accompanied by a strong brand. Study 3 extended these findings by demonstrating that strong brands only increase the impact of attractive designs when perceived risk is high but not when it is low.  相似文献

The advertising industry is undergoing major changes as markets and clients become more global. Using the integration-responsiveness framework and the transnational framework, it is apparent that advertising agencies have a high need to be simultaneously integrated and responsive. This paper reports on a series of depth interviews with international agency leaders intended to gain an assessment of both the extent to which their firms are responding to these important but conflicting needs and the appropriateness of the framework for understanding the strategic options available for ad agency management. The findings indicate that the agencies have tried to modify their strategies to accommodate both kinds of pressures. However, their success in this regard is questioned and other broader strategic concerns are considered.  相似文献
