We produce first estimates of the sustainability of homeownership for recent Federal Housing Administration (FHA) borrowers. Unfortunately, the FHA does not produce its own statistics on sustainability. Neither does it permit researchers access to its data on internal refinances. This imposes significant barriers to entry for researchers who wish to track FHA borrower performance over time. We carefully construct the required tracking data to overcome this barrier. We forecast that no more than 75% of the 2007–2009 vintages of FHA borrowers will be able to successfully exit the FHA system. Our work raises questions about FHA's role, its accounting and its accountability.  相似文献

In this paper, we develop a dynamic supernetwork framework for the modeling and analysis of supply chains with electronic commerce that also includes the role that relationships play. Manufacturers are assumed to produce a homogeneous product and to sell it either through physical or electronic links to retailers and/or directly to consumers through electronic links. Retailers, in turn, can sell the product through physical links to consumers. Increasing relationship levels in our framework are assumed to reduce transaction costs as well as risk and to have some additional value for both sellers and buyers. Establishing those relationship levels incurs some costs that have to be borne by the decision-makers in the supernetwork, which is multilevel in structure and consists of the supply chain and the social network. The decision-makers, who are located at distinct tiers in the supernetwork, try to optimize their objective functions and are faced with multiple criteria including relationship-related ones and weight them according to their preferences. We establish the optimality conditions for the manufacturers, retailers, and consumers, derive the equilibrium conditions, and provide the variational inequality formulation. We then present the projected dynamical system, which describes the disequilibrium dynamics of the product transactions, relationship levels, and prices on the supernetwork, and whose set of stationary points coincides with the set of solutions of the variational inequality problem. We also illustrate the dynamic supernetwork model through several numerical examples, for which the explicit equilibrium patterns are computed.  相似文献

This paper is a study of the perceptions of young adults in the U.S. and China on the relations between the two nations. We conducted a case study by distributing a 17 question survey to 201 American undergraduate students (NYC) and 164 Chinese undergraduate students (Shanghai). The questions probed their views of U.S. and China’s economic and political systems, the future economic growth and political power in the world of the two nations, and the future political and economic relations between the two powers. The results of our study reveal a number of important perceptions that both U.S. and Chinese students have, some being similar and others being in sharp contrast. Most students in both countries view future political and economic relations between the U.S. and China predominantly as cooperative but only based on each nation’s self-interests. Both Chinese and American students agree that China is gaining political strength and economic influence among the advanced and the emerging nations of the world. While most of the U.S. students believe that China has been and will continue to grow at a much faster rate than the U.S., Chinese students are more likely to believe that this rate of growth is unsustainable. The results from our survey are compared and contrasted to the findings of national surveys for both countries. We believe that the study provides valuable insights into the similarities and differences in viewpoints of the next generation of adults in both nations about future U.S.-China relations.  相似文献

This paper investigates the relationship between the practices put in place by firms to search for local and distant knowledge, ambidexterity and firms’ performances; attention is then focused on analysing the antecedents and consequences of ambidexterity in the search phase of the innovation process. Structural equation modelling has been used in order to test these hypotheses in a sample of Italian high-tech companies. Results of the study show a positive impact of the practices used by firm to search for distant knowledge on both ambidexterity and firms’ performances as well. Implications of these results are discussed in the paper.  相似文献

This paper provides a systematic assessment of how entrepreneurs react to firm failure. We use appraisal theory as an overarching theoretical framework and hypothesize that the more the failure experience is appraised as stressful in terms of its implications for harm or loss, the greater the feelings of grief. To test this hypothesis we developed a unique database of entrepreneurs who recently filed for firm bankruptcy. Our results support that there is great variation in responses to firm failure, and we provide theoretically valid explanations to why this is the case. These findings have substantial implications for how scholars conceive and theorize about entrepreneurial failure.  相似文献

Trademarks protecting the brand name and associations are crucial in a brand's strategy, but little is known about the factors that determine a trademark's prolongation. To explain the prolongation of trademarks, the research estimated a multilevel hazard model accounting for trademark characteristics, firm's characteristics, and firm's country of origin national culture. The dataset comprises a census of 2911 trademarks in the US software security industry across an eight-year period, belonging to firms originating from 11 countries. The results indicate that a firm's culture of origin has a systematic effect on the types of trademark the firm is more likely to prolong and on the length of the prolongation. The age of the trademark, the number of categories where a particular trademark is present, and the age of the firm increase the likelihood of a trademark's prolongation. Larger and more innovative firms tend to terminate their trademarks earlier.  相似文献

The purpose of this paper is to analyse how different types of controls are applied in different mechanisms for commercialising science, depending on the inter-organisational interactions involved. To achieve this purpose, we followed a multiple-case study design and selected four cases from Uppsala University and the Karolinska Institutet that provided variation in the commercialisation mechanisms (PET Centre, Ångström Materials Academy, Actar, and Karolinska Development). We find that action and result controls dominate in linear ‘spin-out’ funnel mechanisms, while interactive mechanisms entail a combination of action, result and personal controls. However, the inter-organisational interactions also impact which controls are applied in a commercialisation mechanism: conflicting goals between a few closely related organisations or limited external interactions are associated with result controls, while action controls dominate in the absence of external interactions if time and efficiency are key goals. Result controls also assume very different roles, depending on the inter-organisational context of a specific commercialisation mechanism.  相似文献

We study how financial transactions may respond to exogenous variation in trade opportunities not only directly, but also through policy channels. In more open economies, governments may find it more difficult to fund and enforce public policies that substitute private financial transactions, and more appealing to deregulate financial markets. We propose a simple theoretical model of such policy-mediated relationships between trade and financial development. Empirically, we document in a country panel dataset that, before the 2007–2008 crisis, financial market volumes were robustly and negatively related to the share of government consumption in GDP in regressions that also include indicators of financial regulation and trade openness, and we seek support for a causal interpretation of this result in instrumental variable specifications.  相似文献

The methodological positions of Hayek and Keynes contain striking similarities. Both authors opposed empiricist approaches to economics that assign priority to mere observation as the source of knowledge. Both emphasised intentionality, motivation and human agency. Notwithstanding this common ground, they had different conceptions of how beliefs are formed and had different explanations of thought and action in economics. Hayek grounded his explanation on an evolutionary theory of the mind, i.e. on psychological premises, whereas Keynes based his view of belief formation on probable reasoning, where probability is a logical concept. Starting from psychological premises Hayek maintained that individuals act rationally only by following rules. As a consequence, he considered conventional expectations to be the primary guide for agents in economic life. Keynes agreed that conventional expectations actually guide economic behaviour, but he maintained that they are justified only in situations of total ignorance. In conditions of limited knowledge, agents can base their action on reasonable expectations, independently of conventions. Moreover, agents?particularly those institutions responsible for economic policy?ought to shun conventional behaviour in order to counteract its negative social consequences. We argue that Keynes's theory of expectations is well grounded upon his theory of logical probability. Hence his advocacy of discretionary policy is rationally justified.  相似文献

This study goes beyond subjective personal introspection and applies multiple methods to accomplish a confirmatory personal introspection (CPI) of a long‐term stay in Sweden, during a university exchange program. The utilization of old pictures of the experience is one of the key aspects of the research. This study aims to show the importance of confirmatory personal introspection and assess the meaningfulness of CPI for travel industry related marketing research, exploring further than the ordinary tourist vacations and investigating a broader spectrum of the travel experience, in this case a long‐term travel. Demonstrating the significance of photography relating to travel experiences is an additional objective of the study.  相似文献
