Optimal production of transplant care services

Most organ transplants are from dead donors. National transplant organizations exhibit considerable differences in terms of their donor population rates. Spain's organization is by far the most efficient in this respect. We argue that much of the productivity advantage of Spain's transplant organization proceeds from an efficient organization of the production chain, from organ procurement to transplantation. Transplants from dead donors are analogous to a common resource for the transplant community. Their circulation through the national transplant organization creates public good externalities between the care units in charge of organ retrieval and those in charge of transplantation. A socially efficient production of transplant care services obtains through an optimal control, by the national transplant agency, of both the circulation and the production of transplants. In particular, transplant shortage makes the rotten kid theorem fail in this context. The analysis also produces a natural measure of public good externalities, evaluated from the standpoint of care units.     

Age of first hunting experience: Results from a nationwide recreation survey

Abstract

Hunting participation, as indicated in the 1983 Nationwide Recreation Survey, is examined to determine the relationship between age of first hunting experience and adult level of participation. A statistically significant association between these two variables is found. In addition, more than 83 percent of those who hunt began their involvement by 18 years of age. The findings have implications for future hunting participation and the provision of programs for hunters.     

Poverty and unemployment: A cultural approach

For years, policymakers, business leaders, human resources professionals, and economists have attempted to explain the existence of unemployment. Unemployment inhibits the economic growth of a nation and contributes to the problem of ongoing poverty, which cannot be lessened without that growth. Understanding the causes of unemployment and developing policies and programs to decrease it are vitally important for nations around the world, but one key variable in the study of unemployment has been overlooked. That variable is culture. This article will show that culture can significantly explain cross‐national differences in unemployment rates and offers a link to understanding the global problem of poverty that plagues nations today. © 2012 Wiley Periodicals, Inc.     

The role of a firm's strategic orientation dimensions in determining market orientation

Little is known about how various strategic orientation dimensions determine market orientation. The authors identify four key dimensions of a firm's strategic orientation as critical antecedents to market orientation: the firm's aggressiveness, its future orientation, the extent of marketing formalization, and risk proclivity. Moderating effects of two environmental forces, competitive intensity and technology turbulence, are also considered in light of their relationship with various dimensions of strategic orientation and market orientation. Using a survey with firms spanning multiple industries, the proposed effects are tested with latent class analysis with multiple regimes. The results, based on an optimal two-regime solution, show that that although market orientation is significantly impacted by these strategic orientation dimensions, the pattern of influence differs based on a firm's membership in one of two regimes.     

Access to Flexible Working and Informal Care

We use matched employer–employee data to explore the relationship between employees’ access to flexible working arrangements and the amount of informal care they provide to sick or elderly friends and relatives. Flexitime and the ability to reduce working hours are each associated with about 13% more hours of informal care. Workplaces do not respond to the presence of carers by providing flexible work, instead there is some underlying selection of carers into flexible workplaces. The wider workplace environment beyond formal flexible work may also facilitate care.     

PRIMITIVE ACCUMULATION,GROWTH AND THE GENESIS OF SOCIAL CLASSES

The aim of this paper is to show that inequalities of wealth can be necessary conditions to explain the apparition and rise of a capitalistic system. We try to highlight Marx's insights on primitive accumulation. Our dynamic framework is consistent with Roemer's idea of endogenous class stratification. We extend this calculation by incorporating some features of the Pasinetti–Samuelson–Modigliani model, and provide an example of possible microfoundations.     

Past price ‘memory’ in the housing market: testing the performance of different spatio-temporal specifications

Recent methodological developments provide a way to incorporate the temporal dimension when accounting for spatial effects in hedonic pricing. Weight matrices should decompose the spatial effects into two distinct components: bidirectional contemporaneous spatial connections; and unidirectional spatio-temporal effects from past transactions. Our iterative estimation approach explicitly analyses the role of time in price determination. The results show that both spatio-temporal components should be included in model specification; past transaction information stops contributing to price determination after eight months; and limited temporal friction is exhibited within this period. These findings highlight the decidedly non-linear temporal patterns of such information effects.     

DECISION THEORY UNDER AMBIGUITY

Abstract We review recent advances in the field of decision making under uncertainty or ambiguity. We start with a presentation of the general approach to a decision problem under uncertainty, as well as the ‘standard’ Bayesian treatment and issues with this treatment. We present more general approaches (Choquet expected utility, maximin expected utility, smooth ambiguity and so forth) that have been developed in the literature under the name of models of ambiguity sensitive preferences. We draw a distinction between fully subjective models and models incorporating explicitly some information. We review definitions and characterizations of ambiguity aversion in these models. We mention the challenges posed by some of the models presented. We end with a review of part of the experimental literature and applications of these models to economic settings.     

Credit evaluation,information production,and financial intermediation

Financial intermediaries such as banks, saving and loan institutions, and insurance companies play a large and important role in highly developed economies. The economic significance of financial intermediaries results from their making arrangements between borrowers and lenders more efficiently than if these agents had to trade directly. The intent of this article is to provide a better understanding of the advantage that a financial institution has over an individual lender. This research treats intermediaries as producers of information in the credit evaluation process. The lender produces borrower information that revises the expected profit of the credit decision. Though the production of credit itself holds no economic advantage for institutions over individuals. The opportunity to produce information will provide economies of scale in lending and will help to explain the existence of financial intermediaries.     

Technological experience and the technology adoption decisions in small manufacturing firms

This paper investigates changes in factors bearing on technology adoption decisions in small manufacturing firms. It is hypothesized that, as a firm's experience with technology increases and its technological capabilities grow, the decision process is gradually modified and puts more weight on those factors which are more closely related to the true potential of the technology. An empirical study shows the more innovative firms to have an outward orientation dominated by clients and suppliers, and to pay more attention to the added flexibility brought about by new technology. It is also shown that functional groups within the company play a more important role in the decision-making process.
