regional diversification and firm performance this study examines how regional diversification affects firm performance the results indicate that regional diversification has linear and curvilinear effects on firm performance regional diversification enhances firm performance linearly up to a certain threshold and then its impact becomes negative the results also show that firms of developed countries maximize their performance when they operate across a moderate number of developed regions and a strictly limited number of developing regions this explains why internationalization by most international firms is regional rather than global

rims a new approach to measuring firm internationalization understanding the antecedents to and consequences of a firm s degree of internationalization is integral to international business research in order to be accepted by scholars empirical research that tests hypotheses regarding drivers and or consequences of firm internationalization needs to use a valid measure of firm internationalization in this paper we develop a new measure the ratio of international market shares rims rims measures a firm s degree of conformance to the theoretically grounded characteristics of a maximally internationalized global firm rims is theoretically and empirically compared to three widely used measures of firm internationalization foreign sales to total sales fsts international diversification and international scope each of the three is shown to have serious limitations while rims does not in addition to being theoretically based rims also has the advantages that it measures the degree to which a firm has penetrated the rest of the world s market relative to the degree it has penetrated its primary market captures the combined effects of the breadth and average depth of internationalization is easy to calculate is easy to interpret and is calculable for more firms than measures of diversification or fsts all four measures are tested on a sample of large manufacturing firms

common trends the government s budget constraint and revenue smoothing abstract the requirement that the government s budget be balanced in present value terms is shown to be equivalent to the condition that government expenditures inclusive of interest tax receipts and seignorage be cointegrated the condition is in fact stronger requiring that the deficit inclusive of interest be stationary stationarity of the net of interest deficit is neither necessary nor sufficient for intertemporal budget balance however it does have implications for barro s tax smoothing hypothesis data for the period 1890 1986 are consistent with intertemporal budget balance but not with tax smoothing

the sustainability of government deficits implications of the present value borrowing constraint this paper introduces a new methodology for evaluating the sustainability of fiscal policy the new methodology is distinguished from most existing tests in two important respects first it allows for stochastic real interest rates and second it is both necessary and sufficient results from the application of the new test suggest that recent fiscal policy in the united states has not been sustainable the paper contrasts its findings with those of james d hamilton and marjorie a flavin 1986 copyright 1989 by ohio state university press

imperfect risk adjustment risk preferences and sorting in competitive health insurance markets abstract i develop a model of insurer price setting and consumer welfare under risk adjustment a policy commonly used to combat inefficient sorting due to adverse selection in health insurance markets i use the model to illustrate graphically that risk adjustment causes health plan prices to be based on costs not predicted by the risk adjustment model residual costs rather than total costs either weakening or exacerbating selection problems depending on the correlation between demand and costs predicted by the risk adjustment model i then use a structural model to estimate the welfare consequences of risk adjustment finding a welfare gain of over 600 per person year

is the budget deficit too large yes specifically we find that recent spending and taxing policies of the government if continued violate the government s intertemporal budget constraint as a result government spending must be reduced and or tax revenues must be increased these conclusions are based on tests of whether government spending and revenue are cointegrated in addition to examining real spending and revenue we also normalize these variables by real gnp and population for a growing economy these normalized measures are perhaps more pertinent we also test and find support for the hypothesis that deficits have become a problem only in recent years

sustainability of the deficit process with structural shifts this article discusses the condition for deficit sustainability and searches for shifts in the structure of u s deficit policy i show that contrary to the current literature cointegration between revenues and expenditures inclusive of debt payment is not a necessary but a sufficient condition for a strict interpretation of deficit sustainability the necessary condition requires that debt grow slower than the borrowing rate for tests on structural shifts i use a test for structural change that searches for shifts in the rank of the cointegrating matrix i find that there is a shift in deficit policy in the early 80s so that cointegration between revenue and expenditure inclusive of interest payments holds only up to 1980 i show however that the deficit process is still sustainable despite the failure of cointegration in the 80s the finding of shifts in the deficit process is more uncertain when i normalize by gross national product or population but the deficit is shown to be sustainable regard

on the limitations of government borrowing a framework for empiricaltesting this paper seeks to distinguish empirically between two views on the limitations of government borrowing according to one view nothing precludes the government from running a permanent budget deficit paying interest due on the growing debt load simply by issuing new debt an alternative perspective holds that creditors would be unwilling to purchase government debt unless the government made a credible commitment to balance its budget in present value terms we show that distinguishing between these possibilities is mathematically equivalent to testing whether a continuing currency inflation might be fueled by speculation alone or is instead driven solely by economic fundamentals empirical tests which have been developed for this economic question lead us to conclude that postwar u s deficits are largely consistent with the proposition that the government budget must be balanced in present value terms this abstract was borrowed from another version of this item

multiple dimensions of private information evidence from the long term care insurance market we demonstrate the existence of multiple dimensions of private information in the long term care insurance market two types of people purchase insurance individuals with private information that they are high risk and individuals with private information that they have strong taste for insurance ex post the former are higher risk than insurance companies expect while the latter are lower risk in aggregate those with more insurance are not higher risk our results demonstrate that insurance markets may suffer from asymmetric information even absent a positive correlation between insurance coverage and risk occurrence the results also suggest a general test for asymmetric information

investment effects of departures from governmental present value budget balance the paper investigates whether departures from government borrowing constraints affect the relationship between fiscal policy innovations and changes in the investment level break points or apparent departures from present value budget balance are then identified next the investment deficit relationship is examined prior to and following identified break points in an effort to detect potential changes in behaviour the investment deficit relationship is quantified by examining posterior coverage bounds of impulse response functions britain appears to undergo such a break around 1973 data from this country suggest that significantly more crowding out occurred following the identified breaks in contrast data from other comparison countries that do not appear to have experienced breaks indicate stable investment deficit relationships

measuring the degree of internationalization of a firm in spite of both positivistic and instrumental research the reliability of measuring the degree of internationalization of a firm remains speculative we collected data on nine attributes of seventy four american manufacturing mncs alpha factor and frequency analyses revealed a linear combination of five variables with a reliability coefficient of 79 as a measure of the degree of internationalization of a firm we discuss the statistical and conceptual properties of the scale and their implications for content and construct validity

cointegration and government borrowing constraints evidence for the united states testable implications are derived in a present value borrowing constraint model for the u s federal government critical values for unit root and cointegration tests are calculated with monte carlo studies cointegration techniques are employed to determine whether the government has been involved in perpetual debt financing in recent years the data reject this assertion

interest rates and expected future budget deficits in the united states several recent empirical studies have found no evidence of a positive association between interest rates and current and past budget deficits one possible explanation for this finding is that interest rates are related much more to the expectation of future budget deficits than to current and past budget deficits in this paper i investigate whether this explanation is valid finding no evidence that it is section ii briefly formulates and discusses the hypothesis under consideration stating some of its implications section iii presents the results of regressing the commercial paper rate moody s aaa bond rate and the ex post real commercial paper rate on current and past government spending budget deficits and real money supplies the regressions have been fitted to the entire sample of monthly data spanning the period between june 1908 and march 1984 and to 11

local regional or global quantifying mne geographic scope this paper proposes a multidimensional index of regional and global orientation that can be used in confirmatory studies with econometric methodologies unlike extant measures the index is objectively scaled and controls for home country orientation and market size differences the index is shown to be consistent with models of internationalization that incorporate different assumptions about investment choice and global competition preliminary results show that large multinationals follow home region oriented internationalization paths although much of the regional effect reported by previous studies in fact reflects strong home country biases

estimating welfare in insurance markets using variation in prices we provide a graphical illustration of how standard consumer and producer theory can be used to quantify the welfare loss associated with inefficient pricing in insurance markets with selection we then show how this welfare loss can be estimated empirically using identifying variation in the price of insurance such variation together with quantity data allows us to estimate the demand for insurance the same variation together with cost data allows us to estimate how insurers costs vary as market participants endogenously respond to price the slope of this estimated cost curve provides a direct test for both the existence and the nature of selection and the combination of demand and cost curves can be used to estimate welfare we illustrate our approach by applying it to data on employerprovided health insurance from one specific company we detect adverse selection but estimate that the quantitative welfare implications associated with inefficient pricing in our particular application are small in both absolute and relative terms

government budget deficits and trade deficits are present value constraints satisfied in long term data abstract we test whether long term data from the u s and u k are consistent with the intertemporal government budget constraint and external borrowing constraint both individually and simultaneously a very strong test is provided by our focus on whether the present value constraints pvcs continue to hold despite unusual events such as wars that cause a structural break in the short run dynamic behavior of the variables we find that the pvcs hold over the whole sample period the data also indicate that the pvcs continue to hold following events that cause a structural break in the short run dynamics

product design in selection markets insurers choose plan characteristics to sort for profitable consumers in a model with multidimensional types this sorting incentive is proportional to the covariance among marginal consumers between marginal willingness to pay and cost to the insurer standard forms of cost sharing successfully repel costly consumers but reducing plan comprehensiveness instead alienates the risk averse in a perfectly competitive equilibrium the sorting incentive must vanish market power increases insurance quality and welfare nonetheless a competitive equilibrium with positive insurance is possible when insurance value is suciently negatively correlated with cost however in a calibration to handel hendel and whinston 2013 s data equilibrium still fails to exist

fiscal crises and aggregate demand can high public debt reverse the effects of fiscal policy abstract this paper shows how the power of fiscal policy to affect consumption can vary depending on the level of public debt at moderate levels of debt fiscal policy has the traditional keynesian effects current generations of consumers discount future taxes because they may not be alive when taxes are raised or there will be a larger population available to pay the taxes but when debt reaches extreme values current generations of consumers know there is a high probability that they will have to pay extra taxes a fiscal deficit can have a contractionary effect in these situations

does psychic distance moderate the market size entry sequence relationship an analysis of 924 foreign market entries made by a sample of chinese exporters reveals that psychic distance moderates the relationship between foreign market size and entry sequence in doing so this study challenges the extant hypothesis that the establishment of foreign operations conforms to a simple pattern of increasing psychic distance to markets the findings also reveal that psychic distance is asymmetrical in nature and that assessments made by sellers and their buyers are inherently inequivalent

fiscal policy and the term structure abstract this paper investigates the empirical association between deficits in interest rates it extends the results in plosser 1982 to include the more recent experience the association between a measure of ex ante real rates and deficits is also considered the results largely corroborate the previous results first little or no association between real or nominal interest rates and deficits is found second output and to a lesser extent military spending are found to have a significant association with interest rates

how does risk selection respond to risk adjustment new evidence from the medicare advantage program to combat adverse selection governments increasingly base payments to health plans and providers on enrollees scores from risk adjustment formulae in 2004 medicare began to risk adjust capitation payments to private medicare advantage ma plans to reduce selection driven overpayments but because the variance of medical costs increases with the predicted mean incentivizing enrollment of individuals with higher scores can increase the scope for enrolling overpriced individuals with costs significantly below the formula s prediction indeed after risk adjustment ma plans enrolled individuals with higher scores but lower costs conditional on their score we find no evidence that overpayments were on net reduced

assessing the mean reversion behaviour of fiscal policy the perspective of asian countries this article investigates fiscal policy sustainability in 10 asian countries by adopting a battery of unit root tests univariate unit root tests reveal that the fiscal stance in these countries follows a nonstationary process while the opposite conclusion was drawn for the same dataset using the commonly employed panel unit root techniques by utilizing the series specific panel unit root test recently developed by breuer et al 2002 suradf seemingly unrelated regression augmented dickey fuller that allows testing for the presence of nonstationarity within individual cross sections of the panel we found that only cross sections four out of 10 countries in the panel are stationary this means that fiscal deficits in most asian countries are in violation of their intertemporal budget constraint and that the deficits are too large

do budget deficits raise nominal interest rates evidence from six countries abstract it is widely believed that budget deficits raise nominal interest rates this paper shows that the belief has no empirical support for six countries ricardian equivalence may explain the lack of a positive association between budget deficits and nominal interest rates

adverse selection and inertia in health insurance markets when nudging hurts this paper investigates consumer inertia in health insurance markets where adverse selection is a potential concern we leverage a major change to insurance provision that occurred at a large firm to identify substantial inertia and develop and estimate a choice model that also quantifies risk preferences and ex ante health risk we use these estimates to study the impact of policies that nudge consumers toward better decisions by reducing inertia when aggregated these improved individual level choices substantially exacerbate adverse selection in our setting leading to an overall reduction in welfare that doubles the existing welfare loss from adverse selection jel d82 g22 i13 a number of potential impediments stand in the way of efficient health insur ance markets the most noted of these is adverse selection first studied by akerlof 1970 and rothschild and stiglitz 1976 in insurance markets prices reflect the expected risk costs of the insured pool whether the reason is price regulation or private information when insurers cannot price all risk characteristics riskier consumers choose more comprehensive health plans this causes the equilibrium prices of these plans to rise and healthier enrollees to select less comprehensive coverage than they would otherwise prefer

persistent deficits and the market value of government debt summary this paper investigates whether postwar canadian public financial policy satisfies a borrowing constraint direct tests of the present value relation suggested by this constraint shed light on the sustainability of current policy we examine monthly data on canadian federal government finances using tests for cointegration the finding is that the joint behaviour of real debt and real surpluses is inconsistent with intertemporal budget balance for the government one interpretation of this finding is that the government is systematically paying real returns to bondholders by issuing further debt alternatively bondholders may expect the government to finance future interest payments from a source other than primary surpluses e g the sale of physical assets much empirical macroeconomics is concerned with the effects of public financial policies numerous studies have examined whether such policies affect interest rates inflation or national income and its components these examinations raise the question of the efficacy of government budget deficits they generally assume that a borrowing constraint holds in the public finances some positive theories of public debt creation also make this assumption examples include barro s 1979 history of us federal deficits and sargent s 1986 rationalizations of recent us budgetary policy lucas and stokey s 1983 discussion of optimal taxation also involves this assumption hansen roberds and sargent 1987 outline the testable implications of present value budget balance and hamilton and flavin 1986 investigate the feasibility of recurring deficits by directly testing the us federal government s borrowing constraint such tests seem natural given both the recent boom is testing more complicated first order difference equations in macroeconomics and the widespread discussion of current deficits this paper tests the present value borrowing constraint using recently constructed data on the market value of outstanding canadian federal government debt we use monthly rather than annual as in hamilton and flavin data and conduct tests of univariate integration and of bivariate cointegration to investigate the joint time series properties of debt and deficits one finding is that real debt and real surpluses are integrated processes evidence of their cointegration is mixed and point estimates of the cointegrating vector suggest that the expected real rate of return on debt is negative moreover the surplus measured to include interest payments as government spending is nonstationary these findings are inconsistent

government financing decisions and asset returns abstract this paper presents an empirical investigation of the relation between government financing decisions and asset returns in particular the focus is on whether a substitution of debt financing for tax financing of a given level of expenditures is associated with an increase in interest rates the paper brings a different perspective to empirical investigations of government fiscal policies by examining the response of asset prices in an efficient capital market to such policies rather than focusing on aggregate consumption behavior the results are consistent with the idea that asset prices are unrelated to how the government finances its expenditures the results however also indicate that the capital market is not indifferent with respect to the level of government expenditures as higher interest rates are associated with increases in government purchases

adverse selection and an individual mandate when theory meets practice we develop a model of selection that incorporates a key element of recent health reforms an individual mandate using data from massachusetts we estimate the parameters of the model in the individual market for health insurance we find that premiums and average costs decreased significantly in response to the individual mandate we find an annual welfare gain of 4 1 per person or 51 1 million annually in massachusetts as a result of the reduction in adverse selection we also find smaller post reform markups

trigger points and budget cuts explaining the effects of fiscal austerity we propose and solve an optimizing model which explains counterintuitive effects of fiscal policy in terms of expectations if government spending follows an upward trending stochastic process which the public believes may fall sharply when it reaches specific trigger points then optimizing consumption behavior and simple budget constraint arithmetic imply a nonlinear relationship between private consumption and government spending this theoretical relation is consistent with the experience of several countries jel e62 e21 textbook aggregate demand models suggest simple relationships between the government budget and economic activity a cut in the government deficit for example depressing consumption and output though such models heavily influence the design of stabilization policies their micro foundations are unclear and their sharp predictions are not always consistent with reality in many countries large cuts in government spending carried out as part of stabilization programs have led to expansions rather than contractions in economic activity the absence of simple relationships be
