A bstract . The doctrine of freedom of contract, viz. , that each person should have the liberty to enter into and the right to insist on the fulfillment of any rights-respecting contract , is defined and defended as an implication of a Lockean emphasis on natural rights. This natural rights perspective requires the rejection of all collective social goal theories, e.g., utilitarianism , and the rejection of objections to freedom of contract which proceed from such theories. Four specific objections to freedom of contract, each of which appears to flow from an individualistic emphasis on freedom and rights , are considered. But each of these is dismissed either for misconceiving the nature of freedom or for involving an underlying appeal to some implausible social goal theory.  相似文献

Application of the production constrained gravity-type spatial interaction model generally incorporates a “balancing of attractions” procedure to yield the fully constrained condition. Two techniques for balancing a singly constrained gravity model are compared in this note. These are the Federal Highways Administration adjusted attraction factor method and the Furness column and row balancing procedure. This comparison shows firstly that the two techniques are identical, and secondly that the balancing procedure results in an arbitrary distortion of the calibrated distribution function. Furthermore, some empirical results show that the balancing procedure does not necessarily improve the model's predictions on a cell by cell basis. These results indicate that balancing may be an unnecessary as well as undesirable step in the application of the singly constrained gravity model.  相似文献

The stock of real estate loans held by New England banks has declined dramatically. Given the limited potential for real estate investments, weak demand for real estate loans is to be expected. However, supply as well as demand factors may account for some of the decline in bank real estate loans. This paper documents that bank lending for real estate may have been constrained by a capital crunch, whereby poorly capitalized banks shrank their assets, including real estate loans, to satisfy capital requirements. Because the loss of bank capital is so widespread in New England, bank-dependent borrowers may have difficulty obtaining real estate financing.  相似文献

In this paper we investigate the macroeconomic impact of natural disasters in developing countries by examining hurricane strikes in the Central American and Caribbean regions. Our innovation in this regard is to employ a wind field model on hurricane track data to arrive at a more scientifically based index of potential local destruction. This index allows us to identify damages at a detailed geographical level, compare hurricanes' destructiveness, as well as identify the countries that are most affected, without having to rely on potentially questionable monetary loss estimates. Combining our destruction index with macroeconomic data we show that the average hurricane strike caused output to fall by at least 0.83 percentage points in the region, although this depends on controlling for local economic characteristics of the country affected and what time of the year the storm strikes.  相似文献

This paper investigates whether the sources of income, not just the levels, determine whether an individual is monogamous. Our results support the idea that polygyny stunts development by allowing wealthy men to acquire wives rather than investing in child quality.  相似文献

Hospital and health system finance leaders should position their organizations to participate in the variable-rate market. To this end, one important step is to establish the right baseline variable-rate exposure target for the organization based on its credit and risk profile. Leaders also should be thoroughly familiar with the available products and understand the circumstances (pricing, terms, and embedded risk) under which the organization would be willing to deploy them within the overall capital structure.  相似文献

This case is designed to help you to understand one of the fundamental concepts underlying audits of financial statements: the impact of testing controls on the substantive audit testing to be conducted. When determining the nature, timing and extent of substantive testing, the auditor must consider the costs involved in testing controls and compare that cost to the savings in substantive testing that can occur by relying on the tested controls. In other words, the auditor trades off control testing and substantive testing to determine the best mix of procedures. Similarly, for substantive evidence, the auditor must determine the best mix of substantive analytical procedures and tests of details. In this case, you will assess the trade-offs between the various types of auditing procedures (tests of controls, substantive analytical procedures and tests of details) to determine the optimal audit strategy.  相似文献

In order to remain fiscally solvent, governments of many countries have reformed their public pension schemes to encourage labor supply at older ages. These reforms include reductions in the generosity of public pensions and reduced penalties for working past the normal retirement age. In this paper, we consider how reforms to public pension systems affect labor supply over the life cycle. We put the recent empirical evidence on the effect of government pensions on labor supply in a life cycle context, and we present evidence on the effectiveness of tax reforms for stimulating labor supply over the life cycle. Our main conclusion is that the labor supply of older workers is responsive to changes in retirement incentives. The labor supply of younger workers is less responsive. Thus the trend towards lower taxes on older workers in many developed countries should continue to fuel their trend towards later retirement.  相似文献

Marketing researchers have become increasingly interested in spatial datasets. A main challenge of analyzing spatial data is that researchers must a priori choose the size and make-up of the areal units, hence the resolution of the analysis. Analyzing the data at a resolution that is too high may mask ??macro?? patterns, while analyzing the data at a resolution that is too low may result in aggregation bias. Thus, ideally marketing researchers would want a ??data-driven?? method to determine the ??optimal?? resolution of analysis, and at the same time automatically explore the same dataset under different resolutions, to obtain a full set of empirical insights to help with managerial decision making. In this paper, we propose a new approach for multi-resolution spatial analysis that is based on Bayesian model selection. We demonstrate our method using two recent marketing datasets from published studies: (i) the Netgrocer spatial sales data in Bell and Song (Quantitative Marketing and Economics 5:361?C400, 2007), and (ii) the Pathtracker? data in Hui et al. (Marketing Science 28:566?C572, 2009b; Journal of Consumer Research 36:478?C493, 2009c) that track shoppers?? in-store movements. In both cases, our method allows researchers to not only automatically select the resolution of the analysis, but also analyze the data under different resolutions to understand the variation in insights and robustness to the level of aggregation.  相似文献

Is it better to move first, or second—to innovate, or to imitate? We show that if one player's information about the profitability of new markets is only modestly superior, the possibility of foreclosing the market can lead to a first‐mover advantage. On the other hand, more extreme information superiority can reverse this, leading to a second‐mover advantage. Knowing more surely what is the best choice, the better‐informed player wants to delay to keep his information private and the less‐informed player wants to delay to learn. Because of this, more accurate information can actually lead to inefficiency by increasing the incentive to delay, and exogenous costs of delay can aid efficiency by neutralizing that strategic incentive. In fact, in some circumstances a player may purposely coarsen his information to deter imitation.  相似文献
