RENT SEEKING CAN PROMOTE THE PROVISION OF PUBLIC GOODS*

Public officials often have little incentive to spend time and effort proposing policies that benefit others. When, however, some public policies generate rents to these officials, rent seeking in politics can motivate them to provide public goods. We consider the motivational effects of rent seeking on (i) policy, (ii) the the role of agenda-setting in social choice theory, (iii) the effects of graft and corruption in government, and (iv) the validity of cost-benefit analysis.     

Perspectives on poverty and income inequality in Brazil

Exploratory analysis of the advance tabulations of the 1980 Brazilian demographic census suggests the proportion of the population in poverty fell during the decade 1970–1980. The degree of inequality of the distribution of the income of individuals apparently remained about the same from 1970 to 1980, after rising in the 1960s. This near-constancy of the overall inequality of income distribution resulted from two offsetting changes: a narrowing of the gap between rural and urban incomes, and greater inequality within the rural sector.     

Mortgage Refinancing with Asymmetric Information

Information asymmetry exists between the lender and the borrower regarding the holding period of the mortgaged real estate; the lender does not know how long the borrower plans to own the house. This information asymmetry allows the cost of obtaining a mortgage to deviate from its value to the borrower. As a result, the exercise price of the option to refinance becomes the cost to the borrower of obtaining a new mortgage instead of the outstanding balance of the existing mortgage as used in previous models. The option to refinance is a sequential option; after the borrower refinances, a new option is obtained to refinance again in the future. A mortgage refinancing model is developed taking information asymmetry and sequential refinancing into account. The model is used to solve for (1) the value to the borrower of a callable mortgage and (2) the minimum interest rate differential between the contract rate of the existing mortgage and the market interest rate needed to justify refinancing.     

Market Risk of Mortgage-Backed Securities with Consistent Measures

Due to the complex prepayment behavior, mortgage contracts and their derivatives are generally priced using Monte Carlo simulations. The typical approach used by the industry, which involves simulating interest rates under the risk-neutral measure and applying a physically measured prepayment function, is subject to the problem of internal inconsistency. This is the first paper that directly investigates the potential impact of this issue. Following the general equilibrium setting by Cox, Ingersoll and Ross, we incorporate the market risk price parameter to derive the physical interest rate process from an observed yield curve. This allows us to model mortgage values under the consistent physical measures of interest rates and prepayment functions. By analyzing a default-free Ginnie Mae MBS, we find that the mixed measures lead to slower prepayment rate estimates and overpriced mortgage securities by approximately 5%. Further, there can be substantial biases in the duration and convexity measures depending on market condition and the particular security of interest. The internal inconsistency also leads to biased predictions of both expected and stressed returns for different investment horizons. Depending on the particular security, the bias in expected and stressed returns can be either positive or negative. These biases in risk estimates can introduce misallocation of risk-based capital and/or failure in hedging the market risk of a mortgage-related portfolio.

Benefits sought by the employed care giver

More than 600 full-time employed care givers of older family members reported the impact of care giving on their work performance. While a large proportion reported a minimal negative impact on work performance, this impact was positively correlated with the extent of their care giving burden. When asked what employers could do to help, employees most often requested flexibility.     

Additional Information in Accounting Reports: Effects on Management Decisions and Subjective Performance Evaluations Under Causal Ambiguity

Organizations have often been criticized for reliance on a single item of accounting information (e.g., profit) in evaluating performance, because of its incompleteness. We provide theory‐based experimental evidence that under frequently occurring performance‐evaluation conditions (subjective performance evaluation, causal ambiguity, and individual differences in cognitive ability, knowledge, and/or motivation that lead to different interpretations of information), reliance on a single item of accounting information (profit), rather than profit plus additional (e.g., nonfinancial or external) information, can provide two potential benefits which offset the costs of information incompleteness. First, subordinates are more likely to make the management decisions that superiors will evaluate and reward highly—that is, there are fewer coordination failures in management decisions. Second, even after controlling for the presence or absence of coordination failures, subordinates experience less negative surprise about their performance evaluations.     

Supply Chain Collaboration,Integration, and Relational Technology: How Complex Operant Resources Increase Performance Outcomes

How firms coordinate efforts to collectively compete as supply chains is a key concern of supply chain management scholars and practitioners. One avenue, the development of collaborative relational capabilities that support supply chain integration, offers promise. However, the effectiveness of collaboration as a supply chain resource has been questioned due to concerns associated with collaborative technologies, and thus prior research has called for a deeper examination of the role that technologies play in facilitating integration. Employing a Service‐Dominant Logic view of hierarchical resources, grounded in Resource Advantage Theory, this research tests a model subsuming relationships between collaboration, integration, and interfirm coordination technologies, and their associated performance outcomes. A sample of 282 supply chain managers from a variety of industries were surveyed, with proposed relationships examined employing structural equation modeling. Test results indicate that collaboration and integration interact to form higher order resources that collectively influence firm performance outcomes through interfirm coordination technologies.     

The use of real options valuation methodology in enhancing the understanding of the impact of climate change on companies

Climate change has in recent years gathered traction on the business, political and social agenda. From the business perspective, research has shown that climate change impacts on company value are uncertain, significant and strategically important. The challenge therefore is for the business community to apply financial valuation models that support the incorporation of the climate change impacts in strategic planning. However, the commonly used discounted cash flow techniques in capital budgeting are seen as failing to address the high levels of uncertainties inherent in climate change impacts. Real options thinking has been touted as having the potential to enhance understanding of these impacts via its direct handling of uncertainty, although not much research has been done to demonstrate this. Using an illustrative case study, this research presents an argument for introducing the real options approach, a new method for valuing options of future strategic action by companies in a setting that exhibits climate change impacts. The objective of this research is to contribute to the literature on strategic tools for addressing climate change and ultimately offer some management insights that can narrow the gap between finance theory and business practice.

Factors affecting the size of the labour force and the level of earnings in U.K. agriculture 1948–65

Previous studies of poverty in developing countries have to a great extent focussed on the characteristics of the household head and used these as proxies for the underlying ability of the household to generate income. This paper uses five rounds of panel data to investigate the persistence of poverty in urban Ethiopia, with a particular focus on the role of intra-household heterogeneity in occupations. Dynamic probit and system generalised method of moments regression results suggest that international remittances and labour market status of non-head household members are important determinants of households' poverty status. Results also show that controlling for these variables and the “initial conditions problem” encountered in nonlinear dynamic probit models reduces the magnitude of estimated poverty persistence significantly for urban Ethiopia. These findings have important implications for identifying the poor and formulating effective poverty reduction and targeting strategies.     

Ecosystem Tourism: A Resource-based Philosophy for Ecotourism

Ecotourism has become a popular form of tourism development and marketing in the past ten years, often harnessing the growth in public concern over the wise use of natural resources. In most cases, however, impacts on the ecosystems that are the resource base for ecotourism products are either externalised or their consequences incorporated into the natural evolution of tourism products. This paper is an attempt to stimulate debate on the role that more holistic resource management should play in ecotourism developments. We contend that this can only be achieved through an understanding of ecological science. Credible ecotourism must be firmly based in scientific ecological principles that define ecosystem integrity, especially the resilience of ecosystem processes to disturbance. Such tolerance should be the fundamental measurement against which ecotourism products are monitored.We introduce the term 'ecosystem tourism' to summarise this agenda to define truly sustainable ecotourism development.
