This paper considers structural models with both I(1) and I(0) variables. The structural shocks associated with either set of variables could be permanent or transitory. We classify the shocks as (P1,P0) and (T1,T0), where P/T distinguishes permanent/transitory, while 1/0 means they are attached to structural equations with either I(1) or I(0) variables as their ‘dependent’ variable. We show that P0 shocks can affect cointegration analysis and provide a formula to compute the permanent component if they are present. Finally, we reformulate a well‐known empirical structural vector autoregression showing the impact of P0 shocks when there are just long‐run parametric and sign restrictions.

This paper investigates the effect of foreign aid on governance in order to extend the debate on foreign aid and to verify common positions from Moyo’s ‘Dead Aid’, Collier’s ‘Bottom Billion’ and Eubank’s ‘Somaliland’. The empirical evidence is based on updated data from 52 African countries for the period 1996–2010. An endogeneity robust instrumental variable Two-Stage-Least Squares empirical strategy is employed. The findings reveal that development assistance deteriorates economic (regulation quality and government effectiveness) and institutional (corruption-control and rule of law) governance, but has an insignificant effect on political (political stability, voice and accountability) governance. While, these findings are broadly in accordance with Moyo and Collier on weak governance, they neither confirm the Eubank position on political governance nor the Asongu stance on the aid-corruption nexus in a debate with Okada and Samreth. The use of foreign aid as an instrument to influence the election and replacement of political leaders in Africa may have insignificant results. It is time to solve the second tragedy of foreign aid and that economists and policy makers start rethinking the models and theories on which foreign aid is used to influence economic, institutional and political governance in recipient countries.  相似文献

The aim of the article is to theoretically investigate if a pay‐as‐you‐go (PAYG) pension system is sustainable in the presence of a declining population and increasing longevity of the retired generation. For this purpose, we use an overlapping generation model with endogenous fertility, endogenous longevity and human capital accumulation in a small open economy. We find that pensions will always increase as long as it is beneficial for parents to invest in human capital. Furthermore, we get the result that the ratio between pension benefits and the consumption of the young generation will strive to a positive limit value, and that a pure PAYG pension system will not run into any solvency problem due to a decreasing fertility rate or ageing.  相似文献

Technology has irreversibly changed the way that firms identify who is more likely to buy, what they are more likely to buy, when they are more likely to buy, why they are likely to buy, and how they are likely to buy, repurchase, and recommend. It is now easier than ever for firms to have a body of evidence in the form of actual insights, as opposed to having mere guestimates, on consumers' apparent intentions to buy. Power dynamics have changed in the marketing climate, and firms have to factor in not only aggressive competitors but also empowered customers with limited attention spans. In such a climate, what lies in the future for advertising? And how can marketing managers make the most of the changing climate and maximize their returns on advertising? How can academics advance research related to maximizing the effectiveness and efficiency of advertising? These are the questions that this article addresses via an integrated framework that expounds all the factors related to customers, firms, technological environment, and data resources, as well as the contextual factors, including product life cycle, customer life cycle, and so on, and their collective impact on advertising strategy, which includes advertising content, media selection, message, and targeting.  相似文献

A recent preoccupation in scholarly research is the capacity of firms in developing country industrial clusters to comply with international corporate social responsibility (CSR) policies and codes of conducts. This research is at an early stage and draws on several—often quite distinct—scholarly traditions. In this paper, we argue that future work in this area would benefit from a more explicit examination of the connection between cluster firms and human rights defined according to the 1948 Universal Declaration of Human Rights and subsequent covenants and treaties. We argue that cluster firms’ adoption of CSR policies, often indiscriminately imposed by global buyers, should be differentiated from firms’ actual human rights practices. Based on this distinction, we elaborate a typology of industrial clusters (low-road, window-dressing, rights-oriented) and identify a set of factors likely to influence their practice. Against this background, we discuss an agenda for future research and elaborate on the potential methodological intricacies related to research on the interface between industrial clusters and human rights.  相似文献

Consumption cues (e.g., brands, money, and advertisements) can have powerful effects on cognition, perception, and behavior, yet how people regulate responses to such cues is not well understood. This is surprising given that consumption cues are increasingly present in nontraditional consumer contexts, such as healthcare, education, and politics. This research develops a measure of two types of consumer regulation strategies, cue‐based and budget‐based (studies 1–4), and demonstrates that these strategies influence how people respond to consumption cues in a political context (study 5). Specifically, in a study involving the 2012 American Presidential Election, priming survey participants as consumers (versus citizens) influenced both voting intentions and self‐reported voting behavior, and the newly developed consumer regulation scale was instrumental in detecting this effect. These findings suggest there may be merit in the escalating debate and concern over referring to voters as consumers.  相似文献
