We consider the measures of jointness proposed by Doppelhofer and Weeks ( 2009 ) and Strachan ( 2009 ) in the context of variable selection. Using the general criteria suggested in Ley and Steel ( 2007 ), we identify some shortcomings of these measures, which are illustrated with empirically relevant example cases. We argue that careful examination of the properties of any jointness measure is critical before using it to inform decisions, and favour the use of the measures proposed in Ley and Steel ( 2007 ).

We explore an approach to production frontier estimation based on the direct study of the primary activities in linear technologies. Technologies with smoother isoquants can be thought of as the limit of a linear technology when the number of activities grows to infinity. 相似文献

In the 1990s, Latin American banking sectors experienced an accelerated process of concentration and foreign penetration that prompted diverse views regarding its implications for the competitive behavior of banks and the financial stability of the system. In this paper, we examine these issues exploiting a rich bank-level database for eight Latin American countries. We find that, while increased concentration did not weaken banking competition within the region, foreign penetration appears to have led to a less competitive industry. Moreover, we find that bank risk has been negatively associated with competition which, coupled with the previous finding, explains the positive link between banking sector stability and foreign penetration revealed by the data. 相似文献

Organizational changes have created a need for adaptable pre-trained workers and for employees to have more “protean” career paths and be involved in self-directed ongoing development [Hall & Mirvis, 1995. The new career contract: Developing the whole person at midlife and beyond. Journal of Vocational Behavior, 47(3), 269–289]. To help understand the processes involved in this development, a model of continuous employee development is proposed. This model integrates prior work from career development, training, and education literatures and builds on it by proposing factors that affect the occurrence of future development. Research supporting the model is reviewed and specific testable propositions derived from the variables in the model are given. Recommendations for scale usage in testing the model are also provided. Finally, the novel contributions of the model are highlighted, the practical implications of the model for organizations are outlined, and the role of the education system in these processes is discussed. 相似文献

Using a sample of Chilean listed firms with widespread presence of economic conglomerates that use pyramid structures to control affiliated companies, we find that firms where controlling shareholders have higher coincidence between cash and control rights are persistently more valued by the market. We carefully check that our results are not driven by omitted variable biases and control for reverse causation using a feature of Chilean Corporations Law that provides an exogenous instrument for ownership concentration. 相似文献

General consensus exists concerning the relevance of networks and space in poverty situations, despite a considerable dispute on the prominence of each element. While social‐support and poverty debates highlight the joint importance of space and networks, the research agenda on contemporary communities suggests that networks have recently started replacing space in social integration. These debates mainly consider networks and ties normatively and are restricted to the global North, hampering the formulation of comparative interpretations and more theoretical conclusions. This article discusses the relationship between space, sociability and poverty, based on research results on networks of poor individuals in two major Brazilian metropolises—Salvador and São Paulo. Research indicates the existence of great heterogeneity in the networks of poor individuals, although with substantial differences, on average, to middle‐class individuals. Certain types of networks and sociability are systematically associated with better living conditions, employment and income. Additionally, network mobilization by individuals presents important regularities associated with social mechanisms, understood as regular patterns that trigger or cause certain results. These mechanisms explain to a great extent the heterogeneity of networks, and mediate the individual's access to opportunities and everyday assistance. They therefore contribute decisively to the production (and reproduction) of urban poverty. 相似文献

Joan Robinson’s views on population growth have received scant attention. The aim of this article is to summarize and evaluate aspects of Robinson’s perspectives on population. The population question is considered in terms of four specific topics: the problem of growth, the labor market, effective demand and economic development. The article also interprets Robinson’s approach in light of the endogenous theory of economic growth in order to more explicitly elucidate Robinson’s own statements. It is concluded that an economic interpretation of population growth based on Robinson’s approach requires some specific adaptations if it is to be feasible. It is hoped that this line of approach is useful to scholars of the history of economic thought, economic development or theory of economic growth. 相似文献

This paper re‐examines inflows of foreign direct investment (FDI) in the 32 subnational Mexican states based on quarterly data from 2005 to 2015, which includes rising drug‐related crimes. We estimate our models using panel data methods by type of crime, state‐level indicators (real wages and electricity consumption), macroeconomic forces (the real exchange rate and interest rate), and a dummy variable for the financial crisis of 2008–2009. We employ a flexible lag‐length method and find that homicides and thefts have negative and statistically significant effects on FDI, while other crimes have no effects. Subsample work suggests higher negative effects in the most violent states. (JEL F15, F21, F23, F36) 相似文献

Within the theoretical framework of socio‐political economics, and more specifically of stakeholder theory, this work examines whether companies operating under different institutional constraints and stakeholder pressure tend to emphasize different models of corporate environmental reporting. Furthermore, the paper tests whether different corporate environmental reporting policies are driven by the countries' corporate governance systems. A sample of 3931 international companies was examined through a logistic biplot and conditional mean linear regression models. The main results reveal that companies follow two distinct environmental reporting approaches, which depend on specific stakeholders and institutional requirements. The first model, which is followed by firms within codified law countries, mostly focuses on water and emissions. The second approach, mainly followed by companies operating in common law countries, emphasizes materials and energy issues. This finding reveals that companies gradually modify their environmental strategies to make themselves more compatible with the characteristics of the social and institutional environment, which will result in several corporate benefits. The paper provides several outstanding implications for companies' strategic managers, national institutions and firms' stakeholders, especially for investors and customers.
