Credit constraints and productivity in Peruvian agriculture 总被引:2,自引:0,他引:2
This article evaluates the performance of a rural credit market in Peru. We develop a model that shows that collateral requirements imposed by lenders in response to asymmetric information can lead not just to quantity rationing but also to transaction cost rationing and risk rationing. Just like quantity rationing, these two additional forms of nonprice rationing adversely affect farm resource allocation and productivity. We test the insights of the model using a panel data set from Northern Peru. We estimate the returns to productive endowments for constrained and unconstrained households using a switching regression model. We find that, consistent with the theory, productivity is independent of endowments for unconstrained households but is tightly linked to endowments for constrained households. We estimate that credit constraints lower the value of agricultural output in the study region by 26%. 相似文献

In 2004, a provincial cancer agency in Canada developed and implemented a provincewide Leadership Development Initiative (LDI) to enhance organizational leadership and relationships. Research using a quasi‐experimental survey design determined whether LDI implementation influenced the emotional health and leadership practices of LDI participants. An ethnographic approach (18 focus groups and 13 individual interviews) explored participants' perceptions of the LDI. This article presents qualitative findings that contribute to understanding the statistically significant findings of increasing levels of cynicism, emotional exhaustion, and burnout for most LDI participants. The LDI was regarded as a critical strategy for helping leaders grow and cope with change and help in changing organizational leadership culture to be more collaborative and inclusive. However, an organizational history of short‐lived, flavor‐of‐the‐month development initiatives and growing skepticism and disengagement by leaders represented in the themes of Catch‐22 and “there is no going back” contributes to understanding why these quantitative measures increased. Few studies have explored the hypothesis that real organizational development happens through a series of planned stages. In this study, leaders experienced escalating frustration because change was not seen to occur fast enough in “others” and reported that this was necessary before they would alter their own behavior. Leadership development programs in general need to reflect the reality that it takes considerable time, patience, and effort to effect fundamental change in leadership culture. 相似文献

Has heightened uncertainty been a major contributor to the Great Recession and the slow recovery in the United States? To answer this question, we identify exogenous changes in six uncertainty proxies and quantify their contributions to GDP growth and the unemployment rate. The answer is no. In total we find that increased macroeconomic and financial uncertainty can explain up to 10% of the drop in GDP at the height of the recession and up to 0.6 percentage points of the increased unemployment rates in 2009 through 2011. Our calculations further suggest that only a minor part of the rise in popular uncertainty measures during the Great Recession was driven by exogenous uncertainty shocks. 相似文献

THE VALUATION OF NONMARKET ACTIVITIES IN INCOME ACCOUNTING 总被引:1,自引:0,他引:1
Expanding a conventional national accounting framework in order to include activities that are not produced or consumed via ordinary markets requires the accountant to adopt some procedure for assigning unit values to these activities. Often, as is the case with governmental services, unit values are equated with unit costs of production.
This paper argues that the appropriate valuation generally differs depending on whether the activity is viewed from the perspective of the producer, the consumer, or society. The theoretical justification for this position is developed first for the case of nonmarketed environmental services and then for in-kind governmental transfers.
Rather than choosing a single unit value, the paper argues for and outlines an accounting system that will permit the simultaneous adoption of more than one valuation. Techniques for implementing the system for the environment and for in-kind transfers are discussed.
Finally, drawing on the experience of the authors, the paper argues for the importance of developing data sets with more than one valuation. The authors claim that the effort to implement the system has generated valuable ancillary data sets even though data limitations and unresolved methodological questions have precluded complete implementation. 相似文献

Michael Breuer 《The GENEVA Risk and Insurance Review》2006,31(1):5-9
In the literature on optimal indemnity schedules, indemnities are usually restricted to be non-negative. Keeler [1974] and
Gollier [1987] show that this constraint might well bind: insured could get higher expected utility if insurance contracts
would allow payments from the insured to the insurer at some losses. This paper extends Collier’s findings by allowing for
negative indemnity payments for a broader class of insurers’ cost functions and argues that the indemnity schedule derived
here is more appropriate for practical applications (e.g. in health insurance).

We propose a new method for analysing multi-period stress scenarios for portfolio credit risk more systematically than in current macro stress tests. The plausibility of a scenario is quantified by its distance from an average scenario. For a given level of plausibility, we search systematically for the most adverse scenario. This ensures that no plausible scenario will be missed. We show how this method can be applied to some models already in use by practitioners. While worst case search requires numerical optimisation we show that we can work with reasonably good linear approximations to the portfolio loss function. This makes systematic multi-period stress testing computationally efficient and easy to implement. Applying our approach to data from the Spanish loan register we show that, compared to standard stress test procedures, our method identifies more harmful scenarios that are equally plausible. 相似文献

Risk, Wealth, and Sectoral Choice in Rural Credit Markets 总被引:1,自引:0,他引:1
We model the role of the informal credit sector in developing countries. The informational advantage of informal lenders is portrayed as the ability to monitor borrowers. Monitoring reduces the incentive problem and allows for contracts with lower collateral. This enables informal lenders to serve both individuals who cannot post the collateral required by the formal sector and those who are able but do not want to post collateral. The model is consistent with the conventional view of the informal sector as recipient of spillover demand from the formal sector. It also shows that the informal sector may provide partial insurance as the lower collateral requirement implies greater consumption smoothing for borrowers. 相似文献

This article investigates the influence of gendered occupational identities in the social construction of skill and technology in a retail company introducing an IT system. It focusses on female shop floor supervisors and considers the impact that 'femininity' had on definitions of skill and role during a period of change. 相似文献
