This study uses household-level panel data on smallholder farmers in Ethiopia to estimate how rural population density (RPD) affects agricultural intensification and productivity. Our results suggest that higher RPD is associated with smaller farm sizes, and has a positive effect on input demand, represented by increased fertilizer use per hectare. Overall, increased input use does not lead to a corresponding increase in staple crop yields, and thus farm income declines as population density increases. This suggests a situation where farmers in areas of high RPD may be stuck in place, unable to sustainably intensify in the face of rising RPD and declining farm sizes.  相似文献

This paper analyzes the relationship between trade and agricultural productivity in Chile, a middle-income country with a recent noticeable history of agricultural trade. This study uses an agricultural commodity trade exposure index in a cross-sectional analysis of more than 70,000 farms to study the relationship between the trade exposure of agricultural commodities and the yields reported by these farms in the 1997 Chilean agricultural census. In order to capture both import and export exposure we subdivide farms in two groups, according to the Chilean case: farms producing only importables such as grains (traditional crops), and farms producing both traditional crops and non-traditional agricultural commodities (products more related to export markets). We exclude from our analysis farms producing only non-traditional products because the census only reports yields for traditional crops. We employ a switching regression model to analyze the effects of trade exposure on traditional crop yields for both groups of farms. Results show that the trade exposure index is positively related to farm yields for both groups, but with a larger effect on farmers producing both traditional and non-traditional commodities. These results are important because they suggest that spillovers from both importables and exportables produce gains in the productivity of traditional crops.  相似文献

We conducted an experiment in which we hired workers under different types of contracts to evaluate how flexible working time affects on-the-job productivity in a routine job. Our approach breaks down the global impact on productivity into sorting and behavioural effects. We find that flexible arrangements that allow workers to decide when to start and stop working increase global productivity by as much as 50%, 40% of which is induced by sorting, and 60% represents a motivational effect, mainly driven by more effective working time, with workers reducing the length of their breaks. Our findings also suggest that part-time contracts can enhance global productivity, – though not significant at conventional levels –, and that this effect is also driven by a significant drop in the length of breaks taken. We hence contribute to the literature providing causal evidence of flexibility in routine jobs leading to higher productivity.  相似文献

Nationally representative data for Malawi were used to measure the gender gap in adoption of modern maize and to investigate how, if at all, Malawi’s Farm Input Subsidy Program (FISP) has impacted the gap. Regression results show the probability of adopting modern maize was 12% lower for wives in male-headed households, and 11% lower for female household heads, than for male farmers. Receipt of subsidized input coupons had no discernible effect on modern maize adoption for male farmers. Receiving a subsidy for both seed and fertilizer increased the probability of modern maize cultivation by 222% for female household heads, suggesting the FISP has likely reduced the gender gap in adoption of modern maize in Malawi.  相似文献

Social orientation refers to the extent to which members of an organization are provided with opportunities to have private social contacts and activities outside their work settings. Based upon social interaction and communication flows perspectives, the present research constructs a model depicting the relationships among social orientation, organizational citizenship behavior, R&D-marketing collaboration, and the process performance of new product development program. The empirical results support most hypotheses posited by the authors. In particular, the relationship between social orientation and R&D-marketing collaboration is found to be mediated by organizational citizenship behavior (i.e., helping behavior and civic virtue), and social orientation has no direct effect on the collaboration.  相似文献

Sales force automation (SFA) technologies are increasingly used to support customer relationship management strategies. However, previous studies have reported mixed results about the performances of SFA technologies. Therefore, this study seeks to further examine the impact of SFA usage on both customer relationship quality and sales performance. Additionally, the mediating roles of learning and adaptive selling behaviors on the outcomes of SFA usage are investigated. The results highlight the mediating role of salesperson learning and adaptive selling behaviors in the SFA usage and sales performance relationship. Especially noteworthy is the impact of learning through adaptive selling on those outcome variables. Implications for SFA research and practice that may further improve our understanding of this increasingly relevant topic are also offered.  相似文献

This study explores the impact of investment characteristics, mainly investment location relative to the firm's primary market, on financing choices by real estate investment trusts (REITs). Using a large sample of commercial property acquisitions, we show that REITs are 4–8% less likely to use secured (mortgage) debt when acquiring properties in their primary markets than elsewhere. The documented evidence supports a demand‐side story for the relation between investment characteristics and financing. Moreover, the evidence is consistent with the hypothesis that REITs avoid mortgage financing in their primary markets to preserve operational flexibility in those markets.  相似文献

Use of temporary trade barriers (TTBs) has proliferated across countries, industries, and even policy instruments. We construct a panel of bilateral, product-level US steel imports that are matched to a unique data set on trade policy exclusions that are associated with the 2002 US steel safeguard in order to compare the trade impacts that result from application of various TTB policies over 1989–2003. We find that the trade effects of an applied safeguard—which is statutorily expected to follow the principle of nondiscriminatory treatment—can nevertheless compare closely to the application of the explicitly discriminatory antidumping policy. Our results on trade policy substitutability complement other recent research on these increasingly important forms of import protection.  相似文献

This article tests the hypotheses of convergence to a single level of total factor productivity (TFP), and a steady state of TFP growth rate in China’s agricultural sector. Based on multilateral TFP estimates we found that China’s agricultural sector has rebounded in recent years from a slower TFP growth in the 2005–2007 period. While convergence test results confirm a “catch-up” effect that provinces with lower TFP levels tend to grow faster than others, estimated rates of β convergence are conditional on how we capture the heterogeneity effect across regions. The rates of β convergence range from 0.016 to 0.039 under different model specifications. Estimates show that higher growth rates of educational attainment, R&D, and intermediate goods density (per unit of labor) can enhance TFP growth. Unfortunately, there is no evidence of an overall σ convergence, indicating that TFP levels are not converging except in the South region. It implies that to catch up with leading provinces, it would require extra efforts for those lagging behind by increasing their region-specific research investment, promoting rural educational attainment, and enhancing embodied technical change.  相似文献

Two contrasting views tend to dominate the literature on the impact of recessions on employment. One view is that recessions amount to a ‘critical conjuncture’ for work and employment systems, a time when firms try to transform radically existing employment models. The alternative perspective is that firms, constrained mostly by the forces of path dependency, seek to adjust to the immediate or short‐term pressures of the recession but otherwise maintain the established way of organizing the employment relationship. The purpose of this article is to contribute to this literature by reporting the findings of a major study of the effects of the recession on work and employment in firms based in Ireland. The main finding to emerge from the study is that firms mostly have made improvised adaptations in response to the crisis and have shied away from far‐reaching transformational strategies.  相似文献

The introduction of market mechanisms matters for industrial relations. In the German hospital sector, national liberalization policies have put immense pressure on local management and worker representatives and led to the growth of a low‐wage sector. In case studies of eight hospitals, we find some locales where market making has led to union revitalization and mobilization, but this effect varies. Using an eight‐way comparison, we infer a configuration of three aspects of the local political economy — labour markets, politics and co‐determination rules — that together provide a well‐fitting explanation for both variation and change.  相似文献

Research summary : We investigate the impact of trade secret legal protection on firm market value in the context of acquisitions. On one hand, market value may increase because trade secret assets become better protected from rivals. On the other hand, market value may decrease because trade secret protection reduces information about the target and its competitors available to potential buyers, increasing uncertainty about its value. Buyers will discount their offers in expectation of being compensated for riskier deals. Using a sample of private equity investments in the United States, we find that trade secret protection has a positive effect in industries with high mobility of knowledge workers, but a negative effect in industries with (1) high resource–value uncertainty and (2) high poor‐investment risk. Managerial summary : We argue that an increase in trade secret legal protection might not unequivocally benefit firm owners when selling their business. A stronger trade secret protection increases the market value of firms in industries with high workers' mobility, but it decreases the market value of firms in industries with uncertain resource value and/or high risk of poor‐acquisition investments. Based on the contingent effect of trade secret protection, companies may want to adjust their strategic decisions, including where to locate or relocate, based in part on whether they will derive benefits or suffer losses when trade secrets are better protected. Finally, our study should help policymakers understand more fully the economic impact of government policies associated with trade secrets. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

Using a novel experimental vignette design, this study shows how firm adoption of equal employment opportunity (EEO) policies, internal dispute resolution procedures, occupational segregation, and use of mandatory arbitration agreements affect employment attorney perceptions of employment discrimination claims. Findings reveal the organizational environment of a claim can signal compliance with antidiscrimination law and the use of mandatory arbitration reduces the expected value of a claim and willingness to accept it for representation. These findings contribute to the understanding of antidiscrimination law as a social system by showing organizational environments and mandatory arbitration clauses predict attorney case assessment.  相似文献

Prior work argues that the “market for ideas” supports an open system of innovation, allowing for efficient development of technology across firms. Although this literature has described important features of this market, how it influences the rate and direction of innovation remains an open question. We exploit an exogenous shock to a subset of U.S. medical device firms to study this question. We first document the breakdown in the market for ideas after a federal investigation made it more difficult for the leading orthopedic firms to work with physician‐inventors. We then present evidence of a dramatic decline in the rate of innovation for these firms. Further, a marked shift in direction occurs toward lower‐quality inventions and away from product categories where physician knowledge is critical. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

A large and increasing proportion of agricultural growth in Africa must come from continuous gains in land productivity in areas of high population density and hence with already relatively high yields. What that requires is analogous to the green revolution in Asia. Several features differentiate the African situation. Those include greater diversity in cropping pattern including a historically larger and more widespread tropical commodity export sector. The physical infrastructure in rural Africa is far inferior to that of most Asian countries. While the greater diversity of agriculture calls for a larger and more diverse institutional structure the reality is that the research systems, the ancillary education systems to spread innovation and the rural financial systems are generally greatly inferior to those of Asia at the beginning of the green revolution. Ethiopia’s record of a steady six to seven percent growth for agriculture and nearly halving of rural poverty demonstrates that with the right policies and investments a very poor country starting with poor physical and institutional infrastructure can bring a major contribution from agriculture growth to increased GDP and reduced poverty. As in Asia, the bulk of accelerated agricultural growth will come from small commercial farmers. They have sufficient farm income to reach or exceed the poverty level. Those are farms with, depending on the country, as little as 0.75 hectares to a few tens of hectares of land. They comprise up to half the rural population and produce on the order of 70–80 percent of agricultural output. They are in general not poor. The poor have inadequate land to reach the poverty level, initially with much underemployment, and with substantial non-farm employment. The primary driver of poverty reduction is the small commercial farmer spending on the order of half of increased income on nontradable, employment intensive goods and services from the rural non-farm sector.  相似文献

Research summary: We document the extent of fraudulent reporting among 467 private Chinese technology companies. Comparing the financial statements concurrently submitted to two different state agencies, we demonstrate a systematic gap in reported profit figures in the two sets of books. We find: (1) more than half the sampled companies report incentive‐compatible, materially discrepant profit numbers to the two agencies; (2) politically connected companies are approximately 18 percent more likely to commit fraud and those with venture capital backing are 19 percent more likely to do so; and (3) it pays to cheat. We estimate that companies who “cook” their books have considerably higher odds of receiving an innovation grant. Especially given its prevalence, we conclude that fraud can be a source of performance differential for emerging market companies. Managerial summary: We document that more than half of a sample of 467 private, Chinese technology companies engage in fraudulent financial reporting. By comparing the financial statements companies concurrently submitted to two different state agencies, we demonstrate a systematic gap in reported profit figures in the two sets of books. Relative to the companies without these attributes, we find that politically connected companies are approximately 18 percent more likely to commit fraud and those with venture capital backing are 19 percent more likely to do so. Furthermore, we show that it pays to cheat. We estimate that companies who “cook” their books have considerably higher odds of receiving a government‐sponsored innovation grant. Therefore, fraud can be a source of performance differential for emerging market companies. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

The 2008 food crisis has challenged the political legitimacy and economic efficiency of the liberalization of international agricultural trade. An alternative vision defended by the food sovereignty movement is that long-term food security cannot rely on dependency on food imports, but must be built on the development of domestic production with enough barrier protection to shelter it from world price fluctuations and unfair trading.The purpose of this paper is to look into whether the West African nations can achieve food sovereignty given their various trade commitments and other external constraints. The particularity of our approach is to combine a historical economic analysis with a political approach to food sovereignty and trade commitments.Our results suggest that external brakes on the development of food sovereignty policies are marginal, as the countries still have unused room for manoeuvre to protect their smallholder agriculture under the terms of draft World Trade Organization agreements and Economic Partnership Agreements and under the international financial institutions’ recommendations. Rather the international environment seems to be instrumented by West African states that do not manage to secure a national political consensus to drive structural reforms deemed vital and further the food security of the urban populations over the marginalized rural populations. Recently, the regional integration process has made headway with a common agricultural support and protection policy project that could herald an internal political balance more conducive to food-producing agriculture.  相似文献

Nutritionists and other health experts have recommended a range of dietary plans, and these often differ significantly. Although the USDA food guides have been the most visible in the United States, other dietary plans now are achieving greater public recognition. Our analysis extracts the nutrient recommendations for seven dietary plans and models the recommendations as shifts in demand for the nutrients. Demand shifts for nutrients are combined with nutrient composition shares to simulate the revenue implications in selected agricultural markets. Based on current consumption patterns in the United States, we find that compliance with Harvard’s Healthy Eating Pyramid would generate the greatest revenue gains for specialty crop producers in California.  相似文献
