Operational model for planning the harvest and distribution of perishable agricultural products

This paper presents an operational model that generates short term planning decisions for the fresh produce industry. In particular, the application developed helps the grower to maximize his revenues by making production and distribution decisions during the harvest season. The main motivation for this model comes from the fact that the profitability of producers is highly dependent on the handling of short term planning in the harvest season. Some of the factors affecting profitability include the management of labor costs, the preservation of the value of perishable crops, and the use transportation modes that provide the best trade-off between time (quality of products) and cost. These issues are interrelated, and their judicious management is fundamental for attaining good financial results. The results of the proposed planning model indicate that significant savings can be obtained by managing the trade-off of the freshness at the delivery of the product with the added labor and transportation cost at the grower's side. Moreover the results also show that dynamic, information based, management practices might be preferred over traditional practices based in fixed labor allocation and distribution practices.     

Innovation in Labor Contracts: On the Adoption of Profit Sharing inCanadian Labor Contracts

I present a model in which I show that labor contracts with wages indexed to prices have longer optimal contract lengths and therefore are more likely to adopt performance-related pay. There is empirical support for these predictions in Canadian collective-bargaining agreements. Contract durations are longer in indexed contracts. Performance-related pay is more than twice as likely to be adopted and present in indexed contracts and more likely to be adopted in contracts with longer durations.     

New international business perspectives on Pakistan

What image comes to mind when one thinks of Pakistan? Prior to the attacks of September 11, 2001, and the subsequent invasion of Afghanistan, many businesspeople had little information about this ancient land. Recently, Pakistan has come to the world's attention as a powerful ally in the U.S.‐led war against terrorism. Situated at the crossroads of the Middle East, Southeast Asia, China, and member nations of the former Soviet Union, Pakistan has long been a leading player in regional political and economic activity. This article presents some new perspectives on Pakistan as a market worthy of a closer look. We survey Pakistan's history and geography, as well as its sociocultural, political‐legal, economic, and competitive environments with a view to identifying new opportunities for foreign investors and global marketers. Current business trends and marketing opportunities are discussed, concluding with an outlook for future growth and development. Valuable insights are offered to businesspeople interested in doing business in Pakistan, a little‐studied but vitally important newly industrializing country (NIC) and big emerging market (BEM). © 2004 Wiley Periodicals, Inc.     

The impact of market liberalization on vertical scope: the case of Argentina

This paper analyzes the impact of market liberalization on the vertical scope of firms. Using the case of Argentina, it is shown how the opening of the economy can improve contracting abilities and heighten competition, increasing the ability and incentive of firms to outsource. Survey findings support the main hypothesis as well as the specific importance of reforms relating to inflation, import costs, and heightened demand standards in increasing the use of outsourcing. A case study of the steel producer Siderar, highlights that while firms may reduce their presence in peripheral activities, they may also increase their presence in core areas so as to increase their value proposition.

Credit programs for the poor and the health status of children in rural bangladesh*

The impact of participation in group‐based credit programs, by gender of participant, on the health status of children by gender in rural Bangladesh is investigated. These credit programs are well suited to studies of how gender‐specific resources alter intra‐household allocations because they induce differential participation by gender. Women's credit is found to have a large and statistically significant impact on two of three measures of the healthiness of both boy and girl children. Credit provided to men has no statistically significant impact and the null hypothesis of equal credit effects by gender of participant is rejected.     

Understanding Society: the income data

We introduce the income data of Understanding Society, the UK Household Longitudinal Study. First, we show that the data are widely used in academic and policy research. We then discuss the pros and cons of different types of data on household incomes. We go on to describe the income content of Understanding Society, emphasising key details of data collection and data processing – specifically the derivation of net household income totals. We perform a quality assessment that compares Understanding Society estimates of net household incomes to those from a reliable cross-sectional source – the Households Below Average Income series. We conclude that the Understanding Society income data are of high quality, and so are an excellent source for research on the income distribution or incomes more generally. We finish with a discussion of future directions for income data collection in the study.     

Earnings response coefficient in the MENA region

This article documents the earnings response coefficient (ERC) for nonfinancial firms listed in the Middle East and North Africa region during the period between 2003 and 2013. Our results show significantly positive ERC for our sample firms. The results are robust across different countries and different industries. Our results also show that ERC increases with increasing the measurement interval. It indicates that more information is incorporated in prices as the measurement interval increase. Consequently, we argue that significance of reported earnings is higher for long-term investors in the MENA region.     

Modeling producer responses with dynamic programming: a case for adaptive crop management

Past research found agricultural producers’ conditional responses during the growing season are important adaptations to weather and other stochastic events. Failing to recognize these responses overstates the risks confronting producers and understates their ability to respond to adverse circumstances. Dynamic programming (DP) provides a means for determining optimal long‐term crop management plans. However, most applications in the literature base their analysis on annual time steps with fixed strategies within the year, effectively ignoring conditional responses during the year. We suggest an alternative approach that captures the strategic responses within a cropping season to random weather variables as they unfold, reflecting farmers’ ability to adapt to weather realizations. We illustrate our approach by applying it to a typical cereal farm in Karak, Jordan. The results show that including conditional within‐year responses to weather reduces the frequency of fallowing by 23% and increases expected income by 9%.     

Towards a Democratic New Normal? Investor Reactions to Interim-Regime Dominance during Violent Events

Although interim regimes in former autocracies are generally tasked with initiating a democratic ‘new normal’, they may privately intend to become their country’s new autocratic rulers. We argue that, to cope with the uncertainty stemming from this possibility, investors infer an interim regime’s intentions from the dominance displayed by the regime during government-related violence, as reflected in the share of civilian fatalities. Specifically, we propose that investors interpret higher interim-regime dominance as a signal of weaker democratic intentions and associate such weaker intentions with a gloomier political outlook for local firms. We therefore hypothesize that investors react more negatively to violent events characterized by higher interim-regime dominance. We also hypothesize a less negative effect of such dominance for firms with larger foreign footprints, lower indebtedness, or more concentrated ownership, since investors will likely consider such firms more resilient to political deterioration. Applying event study methodology to 94 spells of violence in Egypt during the Arab Spring, we find substantial support for our hypotheses, thus contributing to management research on investor decision-making, violence, and political uncertainty.     

Natural resources and the tradeoff between authoritarianism and development

Why do African and Middle Eastern countries seem cursed by an abundance of natural resources yet USA, Australia and Norway seem blessed? A growing literature has argued that the benevolence or malignance of natural resources depends upon the quality of institutions. This paper offers a new explanation based on associational freedom and its interaction with the political system. The model predicts that natural resources have an adverse impact on economic performance and transition to democracy in authoritarian regimes but not in democracies. It also predicts that repression of associational freedom will be increasing in natural resources in authoritarian regimes. I test the model's predictions using fixed-effects regressions on an international panel from 1975 to 2000 and find support.
