Double Moral Hazard,Monitoring, and the Nature of Contracts

generalized double-sided moral-hazard model, with risk-averse parties who mutually monitor each other (to get a reasonable idea of outcome/effort). The model considers trade-off between monitoring costs and moral hazard costs, which are endogenously determined by the extent of monitoring. Using this model, we formally prove a generalized version of Coase's conjecture – that the optimal contract minimizes the agency and risk costs. We then show how varying assumptions about the feasibility or cost of monitoring of the outcome or the worker's effort lead to different contracts being optimal. The analysis is then used to explain the nature of contracts observed in practice under many different situations. We will give an explanation as to why industrial workers typically work under wage contracts, while share contracts are common in agriculture and will explain why profit sharing is more common for senior managers than for the production workers.

The impact of the net percentage growth rate in the number of small firms on differential state-level employment growth rates in the US: an exploratory empirical note

This brief exploratory empirical note seeks to identify key determinants of geographic differentials in the percentage growth rate of state-level employment in the US, with the primary focus being on the percentage net growth rate in the number of small firms (i.e., those with fewer than 20 employees) in each state, where this variable serves as a de facto reflection of ‘entrepreneurship’. In the interest of identifying other key factors that influence state-level employment growth rates, the effective income tax rate in each state, quality of life elements and labour market considerations are also included in the analysis. The study period runs from the year 2000 to the year 2007, ending just prior to the ‘Great Recession’. The estimation results imply that the state-level employment growth rate in the US was an increasing function of the percentage net growth rate in the number of small firms in each state. Thus, it appears that the small firms growth rate may in fact be a significant source.     

Managing growth: Human resource management challenges facing the Indian software industry

Indian software industry has had a phenomenal growth in the last two decades and is expected to sustain this momentum in the foreseeable future. Based on content analysis of 25 cases, the paper identifies several human resource management challenges: managing human resources in globally distributed team, shortage of software professionals having sufficient knowledge and competencies, low-skilled nature of the work, lack of well-developed HR systems and processes, high employee turnover, lack of work-life balance, and the problems associated with the use of contract employees. The paper develops a model for managing growth linking the various variables emerging from the study.     

Country of origin: A competitive advantage?

Country of origin has been identified in the literature as an important cue that might be used by global marketers to influence consumers' valuation of the brand. Its effect on consumer perceptions, affect and behavioral intentions has been widely documented, based on consumer surveys and laboratory experiments. Despite this empirical evidence, we argue that country of origin is only one extrinsic cue among many extrinsic and intrinsic cues available to the consumer in a real purchase situation. Furthermore, in real life, consumers are likely to engage in some level of information search, which would further dilute the country of origin effect in the marketplace. Based on these arguments, we conclude that country of origin might not necessarily lead to a competitive (dis)advantage in terms of a price premium or discount. For a sample of products, we show that the objective product quality varies significantly by country of origin, and that these differences are consistent with extant research on country of origin effects on consumers' perceptions. After controlling for quality differences across brands, we demonstrate that marketers from different countries charge prices that are justified by differences in product quality. Price premiums or discounts are therefore explained by differences in product quality rather than the image effect produced by the country of origin cue.     

Brain drain or brain bank? The impact of skilled emigration on poor-country innovation

The development prospects of a poor country or region depend in part on its capacity for innovation. In turn, the productivity of its innovators, whom are often concentrated around urban centers, depends on their access to technological knowledge. The emigration of highly skilled individuals weakens local knowledge networks (brain drain) but may also help remaining innovators access valuable knowledge accumulated abroad (brain bank). We develop a model in which the size of the optimal innovator Diaspora depends on the competing strengths of co-location and Diaspora effects for accessing knowledge. Then, using patent citation data associated with inventions from India, we estimate the key co-location and Diaspora parameters. The net effect of innovator emigration is to harm domestic knowledge access, on average. However, knowledge access conferred by the Diaspora is particularly valuable in the production of India’s most important inventions as measured by citations received. Thus, our findings imply that the optimal emigration level may depend, at least partly, on the relative value resulting from the most cited compared to average inventions.     

Sources of Inequality Between Male and Female Wages in Australia

This article examines the influence of labour force status, full-time/part-time employment status, educational qualifications, work experience, and occupation as sources of inequality between male and female wages in Australia. A decomposition method is used to identify the effect of these factors on male/ female inequality. This strategy involves successively removing persons who differ with respect to each of these factors from the population under study and then decomposing the inequality in the remaining sub-population into inequality within each sex and inequality between the sexes. This decomposition is done using the I₀ inequality index proposed by Theil (1967). The study is based on unit record data from the 1981–82 Income and Housing Survey conducted by the Australian Bureau of Statistics. It finds that a significant proportion of the inequality between the wages of the sexes can be explained by their differences with respect to the factors listed above.     

Projecting total costs and health consequences of increasing mt-sDNA utilization for colorectal cancer screening from the payer and integrated delivery network perspectives

Abstract

Aims: To evaluate total costs and health consequences of a colorectal cancer (CRC) screening program with colonoscopy, fecal immunochemical tests (FIT), and expanded use of multitarget stool DNA (mt-sDNA) from the perspectives of Integrated Delivery Networks (IDNs) and payers in the United States.

Materials and methods: We developed a budget impact and cost-consequence model that simulates CRC screening for eligible 50- to 75-year-old adults. A status quo scenario and an increased mt-sDNA scenario were modeled. The status quo includes the current screening mix of colonoscopy (83%), FIT (11%), and mt-sDNA (6%) modalities. The increased mt-sDNA scenario increases mt-sDNA utilization to 28% over 10 years. Costs for both the IDN and the payer perspectives incorporated diagnostic and surveillance colonoscopies, adverse events (AEs), and CRC treatment. The IDN perspective included screening program costs, composed of direct nonmedical (e.g. patient navigation) and indirect (e.g. administration) costs. It was assumed that IDNs do not incur the costs for stool-based screening tests or bowel preparation for colonoscopies.

Results: In a population of one million covered lives, the 10-year incremental cost savings incurred by increasing mt-sDNA utilization was $16.2 M for the IDN and $3.3 M for the payer. The incremental savings per-person-per-month were $0.14 and $0.03 for the IDN and payer, respectively. For both perspectives, increased diagnostic colonoscopy costs were offset by reductions in screening colonoscopies, surveillance colonoscopies, and AEs. Extending screening eligibility to 45- to 75-year-olds slightly decreased the overall cost savings.

Limitations: The natural history of CRC was not simulated; however, many of the utilized parameters were extracted from highly vetted natural history models or published literature. Direct nonmedical and indirect costs for CRC screening programs are applied on a per-person-per modality basis, whereas in reality some of these costs may be fixed.

Conclusions: Increased mt-sDNA utilization leads to fewer colonoscopies, less AEs, and lower overall costs for both IDNs and payers, reducing overall screening program costs and increasing the number of cancers detected while maintaining screening adherence rates over 10 years.     

Taxes in an e-commerce generation

Rapid growth in e-commerce has altered the ability of jurisdictions to enforce commodity taxes on a destination basis. This results in different effective tax rates depending on the way in which goods and services are purchased and the characteristics of both the products and the sellers. We discuss the arguments for the destination principle as the appropriate place-of-taxation rule for consumption taxation of cross-border trade. We analyze various recent reforms to the value-added tax in the European Union in response to e-commerce. We then examine various policy options in the USA—maintaining the status quo, changing nexus rules, states adopting information reporting, and national reforms that require firms to remit taxes regardless of physical presence—and relate them to the recent European reforms. We conclude based on our analysis and the recent European Union experience that reforms at the national level appear to be the important next step to enforcing commodity taxes at destination in the USA.
