We combine records of Atlanta Housing Authority (AHA) clients, Georgia Department of Labor (DOL) employment records, and neighborhood characteristics to analyze the causal effect of an exogenous move out of public housing on the employment of public housing residents. The exogenous move was caused by a HOPE VI or HOPE VI‐like project in Atlanta. We find that such an exogenous move has a positive and statistically significant effect on the probability of employment for those residents who moved relative to other public housing tenants. We also compare the change in employment of those whose exogenous move was to another public housing unit to those who took a housing voucher. We also compare the change in the probability of employment associated with an exogenous move and a voluntary move and find that both types of moves are associated with a greater probability of employment as compared to those who did not move.  相似文献

Towards Holistic "Front Ends" In New Product Development   总被引:5,自引:0,他引:5  
Any firm that hopes to compete on the basis of innovation clearly must be proficient in all phases of the new-product development (NPD) process. However, the real keys to success can be found in the activities that occur before management makes the go/no-go decision for any NPD project. In other words, the most significant benefits can be achieved through improvements in the performance of the front-end activities—product strategy formulation and communication, opportunity identification and assessment, idea generation, product definition, project planning, and executive reviews. Noting the inherent difficulty of managing the front end, Anil Khurana and Stephen R. Rosenthal discuss findings from in-depth case studies of the front-end practices in 18 business units from 12 U.S. and Japanese companies. They offer a process view of the activities that the front end comprises, and they discuss the insights that their case studies provide regarding key success factors for managing the front-end activities. The case studies involved companies in industries ranging from consumer packaged goods to electronics and industrial products. Foremost among the insights provided by the case studies is the notion that the greatest success comes to organizations that take a holistic approach to the front end. A successful approach to the front end effectively links business strategy, product strategy, and product-specific decisions. Forging these links requires a process that integrates such elements as product strategy, development portfolio, concept development, overall business justification, resource planning, core team roles, executive reviews, and decision mechanisms. The case studies suggest that firms employ two general approaches for achieving these links. Some companies rely on a formal process to lend some order and predictability to the front end. Other companies strive to foster a company-wide culture in which the key participants in front-end activities always remain focused on the following considerations: business vision, technical feasibility, customer focus, schedule, resources, and coordination. This cultural approach is more prevalent among the Japanese firms in the study; the U.S. firms tend to rely on formality of the front-end process. The case studies also suggest that the front-end approach must be compatible with the firm's product, market, and organizational contexts. For example, standardized approaches seem to work best for incremental innovations.  相似文献

Widespread use of the non-steroidal anti-inflammatory drug (NSAID) diclofenac to treat livestock has resulted in dramatic declines in the populations of vultures across India. This has become an issue of considerable concern as vultures are a keystone species and their decline has a range of socio-economic, as well as cultural and biodiversity impacts. In this paper, we review these impacts and estimate in detail the economic cost of one of them: the human health impacts of the vulture decline. Livestock carcasses provide the main food supply for vultures, and are also eaten by dogs. Dogs are the main source of rabies in humans in India, and their populations have increased substantially in parallel with the vulture decline. The potential human health impact of rabies associated with the vulture decline is found to be significant. This, and a wide range of other impacts suggest that significant resources should be put into (1) testing of pharmaceutical products to ensure that similar situations are not repeated, (2) helping vulture populations to recover through the use of alternative drugs to diclofenac that are of low toxicity to vultures, and (3) through conservation breeding programmes.  相似文献

Marketers and consumer researchers have maintained a long-standing interest in understanding continuities and changes in consumer preferences. The present research attempts to provide explanations for stability and changes in consumption patterns by presenting a theoretical framework according to which the results of previous studies may be recast and further research advanced. The authors develop hypotheses and test them with retrospective and longitudinal data, using alternate measures of key variables. The authors suggest implications of the study findings for marketers and theory development, and they provide directions for future research.  相似文献

Using retrospective data on bequest receipts and wealth over two generations of rural Indian households, we have estimated the effect of bequest receipts on the lifetime wealth accumulation of recipients. We exploit the availability of data on two generations of the same household by estimating a family fixed effects model that controls for unobserved, intergenerationally-persistent household endowments. Our results suggest an adverse impact of bequest receipts on the wealth accumulation of recipients. This effect is much more negative for the current generation of household heads than for the previous generation, indicating that the disincentive effects associated with bequest receipts have increased substantially over a generation. Such disincentive effects are consistent with the commonly-observed phenomenon of "regression to the mean." The empirical results also show that the positive association between schooling and wealth accumulation has strengthened substantially over the course of a generation, implying rising returns to schooling.  相似文献

Despite SEC and state-level resistance, and contrary to the trend pursued by other firms, many electric utilities have diversified into non-electric and unregulated businesses. Moreover, this failure to focus has been rewarded with higher firm values, again contrary to the discounts documented in the literature for other diversifying firms. Prior literature has questioned whether these premiums (or discounts) can be attributed to diversification per se. Rather, these premiums could arise from the characteristics of the diversifying firms, which have then endogenously chosen to diversify. In a new approach, where regulation can make the diversification decision largely exogenous, we examine the investment policies of the comparable electric-segments in the diversifying and non-diversifying utilities. We find that single-segment electric utilities over-invest compared to diversifying utilities, which explains their diversification premiums and implies that diversification can create value by opening up new investment opportunities.  相似文献

Notwithstanding their concern with intra‐MNC control mechanisms, scholars have overlooked the complementary phenomenon of self‐regulatory behavior by subsidiaries. In this paper, we take the first steps towards addressing this gap by advancing and testing hypotheses dealing with the determinants of a major element of self‐regulatory behavior at the subsidiary level, i.e., the performance‐oriented feedback‐seeking behavior of subsidiary presidents. Utilizing data from 374 subsidiaries of 75 MNCs, we test hypotheses regarding the impact of subsidiary task and organizational context on the feedback‐seeking behavior of subsidiary presidents. The results of this study can be summarized as follows: (i) subsidiary presidents do engage in proactive performance‐oriented feedback‐seeking behavior; (ii) they vary in the extent to which they engage in such behavior; and (iii) these variations in feedback‐seeking behavior are at least partially systematic.

Newly public firms make acquisitions at a torrid pace. Their large acquisition appetites reflect the concentration of initial public offerings (IPOs) in mergers and acquisitions-(M&A-) intensive industries, but acquisitions by IPO firms also outpace those by mature firms in the same industry. IPO firms’ acquisition activity is fueled by the initial capital infusion at the IPO and through the creation of an acquisition currency used to raise capital for both cash- and stock-financed acquisitions along with debt issuance subsequent to the IPO. IPO firms play a bigger role in the M&A process by participating as acquirers than they do as takeover targets, and acquisitions are as important to their growth as research and development (R&D) and capital expenditures (CAPEX). The pattern of acquisitions following an IPO shapes the evolution of ownership structure of newly public firms.  相似文献

During the financial crisis that started in 2007, the U.S. government has used a variety of tools to try to rehabilitate the U.S. banking industry. Many of those strategies were also used in Japan to combat its banking problems in the 1990s. There are also a surprising number of other similarities between the current U.S. crisis and the recent Japanese crisis. The Japanese policies were only partially successful in recapitalizing the banks until the economy finally started to recover in 2003. From these unsuccessful attempts, we derive eight lessons. In light of these eight lessons, we assess the policies the U.S. has pursued. The U.S. has ignored three of the lessons and it is too early to evaluate the U.S. policies with respect to four of the others. So far, the U.S. has avoided Japan's problem of having impaired banks prop up zombie firms.  相似文献
