The Relationship between Behavioral and Attitudinal Trust: A Cross-cultural Study

We study the relationship between trust in an experiment and trust measured by means of popular survey items in different countries. Students from Chile, Colombia, India, Mexico and Sweden participate in a public goods game experiment and answer a set of standard attitudinal survey questions about trust. We find that behavioral trust and attitudinal trust significantly differ among countries. Behavioral trust is highest in Sweden, followed by Latin America, and lowest in India. Attitudinal trust is highest in Chile and Sweden, followed by India and Mexico, and lowest in Colombia. Further, the predictive power of survey items also differs among countries. Trust measured by survey items is significantly related to behavioral trust in some but not in all societies. No single survey item predicts actual trust across all countries. Plausible explanations of the inconsistent relationship between behavioral and attitudinal trust across countries are discussed.     

A Bangladesh soap opera: privatisation, accounting, and regimes of control in a less developed country

This paper reports an intensive case study of a soap manufacturing company in Bangladesh that was nationalised upon Bangladesh's independence in 1971 and privatised in 1993. Theoretically it is informed by Burawoy's contributions to labour process theory, especially how the consent of labour is manufactured through internal states, internal labour markets and games, and how regimes of control in less developed ex-colonial countries are transformed by state and production politics. How the role of accounting systems may shape and be shaped by these processes is traced. Nationalisation brought state attempts to manufacture consent by the methods described in Burawoy's depiction of hegemonic regimes. However, idealistic attempts to secure accountability, rational planning and control, and consent through bureaucratic means were subverted and transformed into a regime of political hegemony. Here control was secured by political interventions, often at the behest of trade unions, for party political rather than commercial ends. Detailed systems of accounting for control and accountability were maintained but became marginal, ritualistic, and de-coupled from operations. Privatisation brought changes consistent with Burawoy's prediction of coercive controls within a new despotic regime. New owners destroyed the internal state and internal labour markets and, following widespread redundancies, most workers were hired through internal subcontracting. The changes heightened worker divisions and rendered workers powerless to resist. Gaming was observed but this relieved the pressures of work intensification and proved functional to management. Significant changes to accounting controls were made. External reporting ceased in violation of legal requirements — financial accounting became the preserve of the owning family and was beset with irregularities. Budgets became more market oriented and were transmitted downwards in a physical form to reinforce coercive pressures upon managers and thence the shop floor. The paper concludes by relating the findings to a revised model of transformation of control regimes in Bangladesh     

A model for projecting flight delays during irregular operation conditions

On-time performance of airlines schedule is key factor in maintaining current customer satisfaction and attracting new ones. This requires management of the different operation resources (crew/aircraft) to ensure their on-time readiness for each flight in the planned schedule. However, flight schedules are often subjected to irregularity. In particular, weather accounts for nearly 75% of system delays. Due to the tight connection among airlines resources, these delays could dramatically propagate over time and space unless the proper recovery actions are taken. This paper presents a model which projects flight delays and alerts for possible future breaks during irregular operation conditions. The results of applying the model at the operation control center of a major airlines company in the US are presented.     

Weighing what’s practical: proxy means tests for targeting food subsidies in Egypt

Despite achieving a significant cost reduction over the past two decades, the absolute cost of food subsidies in Egypt is still high relative to the benefits received by the poor. There is scope for better targeting these food subsidies, in particular for targeting cooking oil and sugar ration cards, both because reforms in this area are perceived to be far less politically sensitive than adjusting subsidy policy for bread and wheat flour and because higher income groups presently receive a significant percentage of the benefits. Targeting the high-subsidy green ration cards to the poor and the low-subsidy red ration cards to the nonpoor will require identification of both poor and nonpoor households. An International Food Policy Research Institute research team in Egypt, in collaboration with the Egyptian Ministry of Trade and Supply, developed a proxy means test for targeting ration cards. The paper describes the process of moving from the optimal income-predicting model to the final model that was both administratively and politically feasible. An ex-ante evaluation of the levels of accuracy of the proxy means testing model indicates that the model performs quite well in predicting the needy and nonneedy households. An effective and full implementation of this targeting method would increase the equity in the ration card food subsidy system, and, at the same time, the total budgetary costs of rationed food subsidies would decline. Moreover, the experience gained under this reform would facilitate targeting future social interventions to reduce and prevent poverty in Egypt.     

A volume and material handling cost based heuristic for designing cellular manufacturing cells

One of the major problems in a group technology or cellular manufacturing environment is the formation of part groups and machine cells. Because of the combinatorial nature of the cell formation problem, it is difficult to solve the problem optimally. Most of the procedures related to cell design in cellular manufacturing operate on the part-machine incidence matrix in an attempt to identify block diagonality. If complete block diagonality does not exist, the decision about cell configuration is left to the subjective judgement of the designer. These procedures are also generally based on part routing only, and do not consider part volume and material handling costs.In this paper we develop an integer programming model, as well as a heuristic to effectively assign machines to cells. In these procedures we consider component volumes, costs related to movement of components between and within cells, and penalty for not using all machines in a cell visited by a component. Since the integer programming formulation becomes large even for small problems, an efficient heuristic is developed to solve larger problems. The heuristic solutions to 180 randomly generated small problems were compared against the optimal solutions obtained by the integer programming model. The heuristic has been found to identify optimal solutions in all 180 cases.This heuristic is also compared to several well known algorithms on 900 larger test problems. These problems were generated to cover a wide range of environmental situations such as varying levels of block diagonality in the part-machine incidence matrix, and diversity in the component volumes and material handling costs. In 99% of the problems our heuristic generated solutions which are better or as good as the best solution obtained by other algorithms. Further, in situations where complete block diagonality in the part-machine incidence matrix did not exist, our heuristic produced even better results. Since the maximum number of iterations required in our heuristic is the number of machines in the problem, the heuristic is computationally efficient.     

Multidivisional structure and capital structure: The contingency of diversification strategy

This study examines the relationship between the implementation of the multidivisional (M-form) organizational structure, capital structure and diversification strategy. Findings indicate that implementation of the M-form structure from a hierarchical (U-form) structure is associated with a general increase in the long-term debt-to-equity ratio for all firms, a result that supports a free-cash-flow argument for the use of debt in restructuring to reduce the opportunism of management. Further, as implied by arguments from transaction cost economics, the debt-to-equity ration differs for different types of diversification strategy.     

Unemployment and underemployment in Bangladesh agriculture

The paper starts with a critique of the various concepts of unemployment and underemployment from which follows the framework in which the author seeks to investigate and estimate unemployment and underemployment. Unemployment is broken down into various categories so that one can know the composition of the agricultural unemployed and underemployed. All the previous estimates had failed to provide such information. In the rest of the paper various estimates are made and implications discussed in the contest of the framework outlined and using first hand information from a survey of some villages conducted by the author himself.     

Luddites, the industrial revolution, and the demographic transition

Technological change was unskilled-labor-biased during the early industrial revolution, but is skill-biased today. This implies a rich set of non-monotonic macroeconomic dynamics which are not embedded in extant unified growth models. We present historical evidence and develop a model which can endogenously account for these facts, where factor bias reflects profit-maximizing decisions by innovators. In a setup with directed technological change, and fixed as well as variable costs of education, initial endowments dictate that the early industrial revolution be unskilled-labor-biased. Increasing basic knowledge then causes a growth takeoff, an income-led demand for fewer but more educated children, and a transition to skill-biased technological change in the long run.
