Insurer pricing and consumer welfare: evidence from Medigap

This article examines the welfare impact of imperfect competition in the Medicare supplement insurance (Medigap) market. Two firms control nearly three fourths of the Medigap market, and premiums exceed claims by over 25%. I find that a low price elasticity and consumers' brand preferences lead firms to engage in substantial marketing and price above cost. Therefore, the strategic behavior of insurers facing relatively inelastic demand is critical in explaining poor market performance. I also find that insurers do not capture all of the rents in this market; rents also accrue to actors who perform marketing functions, including agents and brokers.     

The evolution of comparative advantage: Measurement and welfare implications

Using novel estimates of sectoral total factor productivities for 72 countries across 5 decades we provide evidence of relative productivity convergence: productivity grew systematically faster in initially relatively less productive sectors. These changes have had a significant impact on trade volumes and patterns, and a non-negligible welfare impact. Had productivity in each country׳s manufacturing sector relative to the US remained the same as in the 1960s, trade volumes would be higher, cross-country export patterns more dissimilar, and intra-industry trade lower than in the data. Relative sectoral productivity convergence – holding average growth fixed – had a modest negative welfare impact.     

The impact of credit scoring on consumer lending

We study the adoption of automated credit scoring at a large auto finance company and the changes it enabled in lending practices. Credit scoring appears to have increased profits by roughly a thousand dollars per loan. We identify two distinct benefits of risk classification: the ability to screen high‐risk borrowers and the ability to target more generous loans to lower‐risk borrowers. We show that these had effects of similar magnitude. We also document that credit scoring compressed profitability across dealerships, and provide evidence consistent with the view that credit scoring may have substituted for varying qualities of local information.     

The impact of nonprofit taxes on foreign direct investment: evidence from German multinationals

This paper provides an empirical analysis of the impact of taxes other than profit taxes on both investment and location decisions of multinationals. Besides effects of corporate income taxes, the results confirm significant adverse effects of nonprofit taxes such as property taxes, sales taxes and VAT, and import duties on the level of FDI. However, once country-specific fixed effects are included, most of the effects of nonprofit taxes vanish. This is supported by the analysis of location decisions, where taxes other than corporate income taxes are not found to exert any adverse effects on the location probability in a setting with country-specific fixed effects.      

The welfare cost of unpriced heterogeneity in insurance markets

We consider the welfare loss of unpriced heterogeneity in insurance markets, which results when private information or regulatory constraints prevent insurance companies to set premiums reflecting expected costs. We propose a methodology which uses survey data to measure this welfare loss. After identifying some “types” which determine expected risk and insurance demand, we derive the key factors defining the demand and cost functions in each market induced by these unobservable types. These are used to quantify the efficiency costs of unpriced heterogeneity. We apply our methods to the US Long‐Term Care and Medigap insurance markets, where we find that unpriced heterogeneity causes substantial inefficiency.     

Economics of welfare: The implications of demographic change for Europe

The author reviews some factors that may necessitate a re-examination of social policy. Since the Second World War the proportion of people aged 65 and over has increased by half in some countries. The probable decline in the age of retirement will further strain resources, and continuing inflation and recession would reduce revenue and increase the cost of benefits.     

Optimal fringe benefit taxes: the implications of business use

Unless fringe benefits are taxed, remuneration may be distorted toward such benefits and away from wages and salaries. A principle for setting such taxes has been proposed in previous work. In particular, the value to workers of fringe benefits would be taxed at a rate equivalent to that on wages and salaries. The current paper reexamines this principle in a model where workers’ valuations are heterogeneous and unobservable to the tax authority. This model does have cases that are broadly consistent with the existing principle, but it also highlights cases in which taxes should be higher on fringe benefits that produce value for the firm.     

The impact of company type and corporate social responsibility messaging on consumer perceptions

Consumer distrust is particularly salient in the context of the current mortgage crisis, and mortgage companies are looking for ways to change their image and regain consumer confidence. This study examines whether advertisements portraying a message of corporate social responsibility (CSR) might help financial institutions in enhancing consumer perceptions of the company. One hundred subjects were randomly selected from among the faculty and staff of a large American university. Subjects were exposed to advertisements, with or without a CSR message, for two well-known service organizations (JP Morgan Chase and Verizon). Results suggest that consumers harbor negative attitudes toward mortgage companies and skepticism about advertising from these companies, but that the inclusion of a CSR message can mitigate these effects, resulting in improved attitudes toward the company. Managerial implications are discussed.     

The impact of consumer behavior on financial security of households in Poland

The paper applies the concept of identity to investigate whether consumer behavior matters for a household's financial security. It is assumed that considerable part of households may express their identity through status-oriented consumption. The research is carried out in two steps. First, the index of financial security is built and used to determine the level of financial security experienced by working-age families in Poland. Second, the simulation results based on an econometric model are employed to find the answer to the question: Does financial insecurity result more from the need to manifest consumption at the higher level than average in an income-group of which people are members, or people want to be distinguishable inside their own income-group but they do not identify with a group having consumption at visibly higher level, or from the need to improve self-image by bringing own consumption closer to the pattern of a group with higher wealth status of which they are not members? The source of data is the 2005-2009 Households Budget Surveys in Poland. The findings offer empirical evidence for the relevance of consumer behavior for financial security of households in Poland. Considerable part of households expresses identity through conspicuous consumption. Both groups of households, the insecurity rich and the insecurity poor, accept the same ranking of status goods: a car on the first position, next homes (housing and equipment) and clothes on the third place. Status-oriented consumption creates life beyond means and pushes even relatively rich households towards financial insecurity.     

Tax policy and planning implications of hidden taxes: effective marginal tax rate exercises

Hidden taxes in the form of floors and phaseouts are prevalent in the current US tax system and can have a considerable impact on the marginal tax rate faced by the taxpayer. It is important that future tax professionals be familiar with the theoretical and practical implications of hidden taxes. This paper provides a series of classroom exercises to illustrate the impact that hidden taxes can have on marginal tax rates. Information for incorporating this material into an introductory tax course is also provided. The exercises help inform students about the impact of specific tax provisions on marginal tax rates and business and investment decisions, while also giving instructors an opportunity to discuss the tax policy considerations that lead to implementation of these provisions.     

The impact of consumer inattention on insurer pricing in the Medicare Part D program

The Medicare Part D program relies on consumer choice to provide insurers with incentives to offer low‐priced, high‐quality pharmaceutical insurance plans. We demonstrate that consumers switch plans infrequently and search imperfectly. We estimate a model of consumer plan choice with inattentive consumers and show that high observed premiums are consistent with insurers profiting from consumer inertia. We estimate the reduction in steady state plan premiums if all consumers were attentive. An average consumer could save $1050 over three years; government savings in the same period could amount to $1.3 billion or 1% of the cost of subsidizing the relevant enrollees.     

The effect of taxes on multinational debt location

We provide new evidence that differences in international tax rates and tax regimes affect multinational firms' debt location decisions. Our sample contains 8287 debt issues from 2437 firms headquartered in 23 different countries with debt-issuing subsidiaries in 59 countries. We analyze firms' marginal decisions of where to issue debt to investigate the influence of a comprehensive set of tax-related effects, including differences in personal and corporate tax rates, tax credit and exemption systems, and bi-lateral cross-country withholding taxes on interest and dividend payments. Our results show that differences in personal and corporate tax rates, the presence of dividend imputation or relief tax systems, the tax treatment of repatriated profits, and inter-country withholding taxes on dividends and interest significantly influence the decision of where to locate debt and the proportion of debt located abroad. Our results are robust to firm and issue specific factors and to the effect of legal regimes, debt market development, and exchange rate risk.     

Agency costs,taxes and debt: The UK evidence

This paper provides an empirical examination of the impact of the corporation tax and agency costs on firms' capital structure decisions. Our evidence suggests that the agency costs are the main determinants of corporate borrowing. Consistent with the agency theory, we find that firms that have fewer growth options have more debt in their capital structure. Moreover, our results show that debt mitigates the free cash flow problem and that firms that are more likely to be diversified and less prone to bankruptcy are highly geared. the negative effect of insider shareholding on leverage disappears, however; when all the agency mechanisms are accounted for. In addition, we find that, in the long run, companies that are tax exhausted exhibit significantly lower debt ratios than tax-paying firms. However, in the short run, firms' capital structure decisions are not affected by taxation.     

The Chinese experience: The impact of financial restatements on firm value and its implications on the investigatory practices of regulators

We examine the relationship between restatements of prior period financial results and firm value in China. This relationship is relevant to the millions of global investors who purchase Chinese equity securities because Chinese regulatory authorities must focus on the restatement events that, in their judgment, most warrant investigation. We recommend that they focus their attention on restatement announcements (and the firms that announce them) that possess the characteristics that most impact firm value.Prior studies of the American equity markets found evidence of a relationship between the nature of the restatement announcements and firm value, as well as evidence that core account adjustments and high-magnitude adjustments affect firm value more than noncore account adjustments and low-magnitude adjustments. However, based on a sample of Chinese listed firms that made corporate announcements that appeared in the Asian press between 2003 and 2011, we only find mixed evidence in the Chinese equity markets in support of the former relationship, and no evidence at all in support of the latter relationship.In other words, restatement announcements in China do not impact firm value to the same extent, and in the same manner, as restatement announcements in America. Chinese regulators must thus develop policies that are unique to the Chinese markets in order to effectively prioritize their oversight activities on firms that issue restatement announcements.What factors should be considered by Chinese regulators? We identify a collection of corporate governance variables, as well as a smaller collection of financial variables, that are significantly associated with decreases in firm value. We also develop a set of regression analyses that utilize these variables to explain a significant portion of the variability of firm value during the sample period. Interestingly, however, we find no evidence that the growth patterns of the firms are significantly associated with changes in firm value.Using this evidence, we recommend the development of a model of regulatory guidance that is customized for the unique characteristics of the Chinese equity markets. We believe that this model can help Chinese authorities focus their attention on specific restatement announcements that most impact firm value.     

Real estate transfer taxes and property values: The Philadelphia story

We examine the effect of the 1988 increase in the Philadelphia real estate transfer tax on the sale price of residential property. We find that sales prices fell, as expected. While sampling variability is slightly higher than desirable, the point estimate of the key coefficient indicates a decrease in house price far greater than what would be expected with perfect capital markets. This may be attributed to either capital market imperfections or the news value of the tax increase. The burden of the transfer tax thus rests on the seller.     

The optimal mix of taxes on money,consumption and income

We determine the optimal combination of taxes on money, consumption and income in transactions technology models where exogenous government expenditures must be financed with distortionary taxes. We show that the optimal policy does not tax money, regardless of whether the government can use as alternative fiscal instruments an income tax, a consumption tax, or the two taxes jointly. These results are at odds with recent literature. We argue that the reason for this divergence is an inappropriate specification of the transactions technology adopted in the literature.     

The compensating behavior of smokers: taxes, tar, and nicotine

Using data from the 1979 and 1987 National Health Interview Survey (NHIS), we test whether smokers alter their smoking habits in the face of higher taxes. Smokers in high-tax states are more likely to smoke cigarettes higher in tar and nicotine. Although taxes reduce the number of cigarettes consumed per day among remaining smokers, total daily tar and nicotine intake is unaffected. Young smokers, aged 18-24, are much more responsive to changes in taxes than are older smokers, and their total daily tar and nicotine intake actually increases after a tax hike. We illustrate that tax-induced compensating behavior may eliminate some health benefits generated by reduced smoking participation. A more appropriate tax might be based on the tar and nicotine content of cigarettes.     

The impact of tax on foreign direct investment: Empirical evidence and the implications for tax integration schemes

We estimate the impact of taxation on foreign direct investment (FDI) flows, using data on flows between seven countries for 1984 through 1989, and a sophisticated measure of the cost of capital. We find that the choice between domestic investment and total outward FDI is not significantly affected by taxation but that taxation does affect the location of outward FDI. These results are used to examine the impact of tax integration systems. Giving a tax credit to foreign shareholders may induce a large increase in inward FDI from exemption countries but not from partial-credit countries. For the United States, the total effect would be small.     

The effect of personal taxes and dividends on capital asset prices: Theory and empirical evidence

This paper derives an after tax version of the Capital Asset Pricing Model. The model accounts for a progressive tax scheme and for wealth and income related constraints on borrowing. The equilibrium relationship indicates that before-tax expected rates of return are linearly related to systematic risk and to dividend yield. The sample estimates of the variances of observed betas are used to arrive at maximum likelihood estimators of the coefficients. The results indicate that, unlike prior studies, there is a strong positive relationship between dividend yield and expected return for NYSE stocks. Evidence is also presented for a clientele effect.
