explaining the border effect the role of exchange rate variability shipping costs and geography this paper exploits a three dimensional panel data set of prices on 27 traded goods over 88 quarters across 96 cities in the us and japan we show that a simple average of good level real exchange rates tracks the nominal exchange rate well suggesting strong evidence of sticky prices focusing on dispersion in prices between city pairs we find that crossing the us japan border is equivalent to adding as much as 43 000 trillion miles to the cross country volatility of relative prices we turn next to economic explanations for this so called border effect and to its dynamics distance unit shipping costs and exchange rate variability collectively explain a substantial portion of the observed international market segmentation relative wage variability on the other hand has little independent impact on segmentation 2001 elsevier science b v all rights reserved

modeling skewness with the linear stochastic plateau model to determine optimal nitrogen rates accurate modeling of skewness is needed to increase the actuarial fairness of crop insurance we test day s conjecture that crop yield skewness becomes negative as nitrogen rates increase and determine how well a linear response stochastic plateau lrsp production function matches the pattern of observed skewness using four long term nitrogen experiments stillwater wheat is consistent with day s conjecture but the skewness for lahoma and altus wheat yields as well as altus cotton yields are not the lrsp assumes normal random effects and can explain only a small part of observed skewness so a new lrsp with skew normal random effects is introduced which comes closer to explaining the observed skewness and should increase the accuracy of nitrogen rate recommendations negative skewness reduced optimal nitrogen rates and positive skewness increased optimal nitrogen rates

fiscal structures and economic growth international evidence i introduction a large and growing body of literature searches for the determinants of economic growth employing cross country regression analysis e g kormendi and meguire 1985 grier and tullock 1989 barro 1990 1991 1992 romer 1989 1990 levine 1991 and levine and renelt 1992 1 the cross country regression approach implicitly assumes that the growth process possesses similar structural properties across the countries in the sample structural differences be they political economic social or other between countries therefore do not condition the growth process or if they do then the effects are randomly distributed with zero mean if structural differences between countries do matter significantly and non randomly in the growth process then the existing cross country research is potentially flawed attempts are sometimes made to control for such differences by including dummy variables for different regions of the world e g dummy variables for african latin american and other groups of countries within the literature on the determinants of economic growth some papers e g landau 1983 1985 1986 kormendi and meguire 1985 ram 1986 koester and kormendi 1989 barth keleher and russek 1990 easterly and rebelo 1993 and fischer 1993 consider the effects if any of government expenditure and revenue on economic growth overall the findings of these studies paint a mixed picture the relationship between growth and government is sometimes significant and positive sometimes significant and negative and sometimes not significant although these studies consider many different fiscal variables they do not as a rule examine the effects of these fiscal variables in a systematic way that controls for the mode of financing they generally overlook for example how an increase in government consumption expenditure is financed is it with higher taxes and which taxes or is it with lower spending and which spending finally is it with a larger deficit controlling for these factors may lead to different findings about the effect of an increase in government consumption expenditure on economic growth borrowing from some work on the effect of fiscal structure on national economic growth within the united states in helms 1985 mofidi and stone 1990 and miller and russek 1993 we introduce the government budget constraint into the regression equations that examine the determinants of economic growth as a result we directly address the three financing questions raised in the previous paragraph in this framework we consider the growth process using pooled times series cross section data and comparing the results from fixed and random effects econometric techniques 2 these techniques attempt to accommodate structural differences between countries and across time we also compare the performance of the more standard ordinary least squares regression approach with that of the fixed and random effect models ii an overview of international fiscal structures before presenting our model and statistical findings a brief overview of the growth and fiscal characteristics of the countries in our sample provides some additional information for those not familiar with the data which otherwise would not be revealed by our analysis 3 this information can contribute in a limited way to the debate about the effects of government on economic growth although it is not a substitute for modeling the growth process for the sample as a whole the growth rate of real per capita gross domestic product gdp averaged 1 35 per year during 1975 to 1984 with a coefficient of variation of 3 52 by comparison the average growth rate in the united states was 1 45 the five fastest growth countries were botswana 6 72 indonesia 4 19 korea 6 32 sri lanka 3 20 and thailand 4 31 the five slowest growth countries were el salvador 1

lines in the sand price dispersion across iraq s intranational borders before during and after the surge abstractthis paper tests the impact of a change in security commitment on market development in a country embroiled in low intensity conflict we analyze weekly price data for approximately 250 goods from 18 iraqi cities between 2005 and 2008 our paper suggests four empirical regularities associated with price dispersion and market development in postwar iraq first the degree of intracountry price dispersion in iraq is higher than that reported for a typical industrialized nation second the degree of price dispersion decreased significantly during 2007 coincident with the change in u s security strategy known as the surge third the economic impact of the surge is geographically uneven but loosely follows patterns of u s deployment with price dispersion decreasing by roughly one third in areas targeted during the surge but remaining relatively static in other areas finally we find that internal ethnoreligious divisions have relatively modest effects on price dispersion

production risk in multi output industries estimates from norwegian dairy farms farmers who produce multiple outputs are portfolio managers in the sense that they use inputs to balance expected economic return and variance of return this article estimates the structure of the stochastic multioutput production technology in norwegian dairy farming allowing for a more flexible specification of the technology than previous studies we find that an increase in input levels leads primarily to higher output variability and that inputs also influence the covariance of shocks between outputs risk reducing effects of inputs on outputs are primarily present in the covariance functions technical change leads to shifts in the profit distribution over the data period but no welfare improvement for risk averse farmers

testing the stochastic structure of production a flexible moment based approach conventional production function specifications are shown to impose restrictions on the probability distribution of output that cannot be tested with the conventional models these restrictions have important implications for firm behavior under uncertainty a flexible representation of a firm s stochastic technology is developed based on the moments of the probability distribution of output these moments are a unique representation of the technology and are functions of inputs large sample estimators are developed for a linear moment model that is sufficiently flexible to test the restrictions implied by conventional production function specifications the flexible moment based approach is applied to milk production data the first three moments of output are statistically significant functions of inputs the cross moment restrictions implied by conventional models are rejected

do state and local taxes affect economic growth this paper tests if variations in the treatment of expenditures by state and local governments are an explanation for the inconsistent results of previous tax studies estimates for net investment and employment in manufacturing for 1962 82 support this conjecture indicating that state and local taxes have a negative effect when the revenues are devoted to transfer payment programs and that with taxes held constant increases in expenditures on health education consistent with the vicious circle phenomenon do not appear simply to reflect common cyclical movements and provide evidence of structural linkages implicit in previous results for growth in state personal income copyright 1990 by mit press

aggregate uncertainty capacity utilization and manufacturing investment theory suggests that the level of uncertainty affects the investment decision for firms although the sigh of the effect is ambiguous a garch m estimator is used to model the conditional variance of gdp as a proxy for uncertainty this measure is then employed in a simple model of the investment decision the results are that the level of aggregate uncertainty has a significant negative effect on manufacturing investment in particular periods there were very large effects on average uncertainty reduces investment by about 5 but in 1974 the effect peacked at 48

insecurity and the pattern of trade an empirical investigation corruption and imperfect contract enforcement dramatically reduce international trade this paper estimates the reduction using a structural model of import demand in which insecurity acts as a hidden tax on trade we find that inadequate institutions constrain trade as much as tariffs do we also find that omission of indices of institutional quality biases the estimates of typical gravity models obscuring a negative relationship between per capita income and the share of total expenditure devoted to traded goods finally we argue that cross country variation in the effectiveness of institutions and the consequent variation in the prices of traded goods offer a simple explanation for the stylized fact that high income capital abundant countries trade disproportionately with each other

the choice of techniques and the optimality of market equilibrium with rational expectations this paper shows that in the absence of a complete set of risk markets prices provide incorrect signals for guiding production decisions even if all individuals have rational expectations concerning the distribution of prices which will prevail on the market next period the market allocation is in general not a constrained pareto optimum essentially the only conditions under which for all technologies the market equilibrium is a constrained pareto optimum are those in which risk markets are redundant we derive the necessary and sufficient conditions for redundancy of risk markets which turn out to be extremely restrictive

public education expenditures taxation and growth linking data to theory governments around the world have taken a prominent role in financing education while justifications for this involvement are varied a common motivation is that education expenditures are a key to sustained economic growth economic theory provides a foundation for this belief many papers in the endogenous growth literature have formalized a link between public education expenditures human capital accumulation and long term growth while theory assigns public education expenditures a key role in growth empirical support for the link is mixed as highlighted by blankenau and simpson 004 the disconnect between theory and data can be reconciled by taking a closer look at the theory in nearly every model where growth is fueled by public education expenditures a nonmonotonic relationship between expenditures and growth can arise public education spending increases growth while taxes may decrease growth leaving the net effect ambiguous thus economic theory shows that to identify the growth effects of expenditures one must account for any offsetting effects of the requisite taxation most empirical investigations of these effects do not explicitly control for the method of finance however in contrast we make the relationship between expenditures taxation and growth central to our analysis we estimate a

poverty political freedom and the roots of terrorism this article provides an empirical investigation of the determinants of terrorism at the country level in contrast with the previous literature on this subject which focuses on transnational terrorism only i use a new measure of terrorism that encompasses both domestic and transnational terrorism in line with the results of some recent studies this article shows that terrorist risk is not significantly higher for poorer countries once the effects of other country specific characteristics such as the level of political freedom are taken into account political freedom is shown to explain terrorism but it does so in a non monotonic way countries in some intermediate range of political freedom are shown to be more prone to terrorism than countries with high levels of political freedom or countries with highly authoritarian regimes this result suggests that as experienced recently in iraq and previously in spain and russia transitions from an authoritarian regime to a democracy may be accompanied by temporary increases in terrorism finally the results suggest that geographic factors are important to sustain terrorist activities this abstract was borrowed from another version of this item

democrats republicans and taxes evidence that political parties matter i estimate the influence of political parties on state tax burdens over a forty year period 1960 2000 holding constant a large number of state and voter characteristic variables i find that i tax burdens are higher when democrats control the state legislature compared to when republicans are in control ii the political party of the governor has little effect after controlling for partisan influences in the state legislature i explain how both findings are consistent with median voter theory my results suggest that after five years of democratic control of the legislature state government would be approximately 3 to 5 percent larger than if republicans controlled the legislature during that same period with the better specifications producing estimates in the higher end of this range

trends random walks and tests of the permanent income hypothesis abstract recent studies find that consumption is excessively sensitive to income these studies assume that income is stationary around a deterministic trend the data however do not reject the hypothesis that disposable personal income is a random walk with drift if income is indeed a random walk then the standard testing procedure is greatly biased toward finding excess sensitivity moreover if income follows either a more general non stationary process or a borderline stationary process this procedure is also seriously biased

does state economic development spending increase manufacturing employment abstract recent studies which have attempted to determine what causes an industrial sector in a state to grow have ignored the general role of the state s economic development agency we extend the analysis to include its effect and determine that economic development expenditure by the state is significantly correlated with manufacturing growth in the state our result is robust to a variety of specification tests

how much does violence tax trade abstract we investigate the empirical effect of violence as compared to other trade impediments on trade flows our analysis is based on a panel data set with annual observations on 177 countries from 1968 to 1999 which brings together information from the rose data set the iterate data set for terrorist events and data sets of external and internal conflict we explore these data with traditional and theoretical gravity models we calculate that for a given country year the presence of terrorism together with internal and external conflict is equivalent to as much as a 30 tariff on trade this is larger than estimated tariff equivalent costs of border and language barriers and tariff equivalent reduction through generalized systems of preference and wto participation

european product market integration after the euro using a detailed data set of prices of consumer goods in european cities from 1990 to spring 2003 we investigate the question of whether the introduction of the euro in january 1999 increased integration of consumer markets as reflected by consumer prices in fact we find no tendency for prices to converge after january 1999 this finding holds even when we control for a number of factors that might affect price dispersion on the other hand we find that there has been a significant reduction in price dispersion throughout the decade of the 1990s suggesting that efforts to reduce economic barriers initiated early in the decade may have in fact had the effect of significantly increasing the integration of consumer markets charles engel and john h rogers

taxes and agglomeration economies how are they related to nonprofit firm location author affiliation teresa d harrison department of economics drexel university 3141 chestnut street philadelphia pa 19104 usa tharrison drexel edu1 introductionnonprofits are an ever increasing component of the u s economy from 1997 2001 employment growth in the nonprofit sector averaged 2 5 outpacing both the business 1 8 and the government sectors 1 6 moore 2004 much of this growth stems from new nonprofits yet few studies have investigated possible determinants of nonprofit entry and location decisions most of these studies focus on demand side factors wolch and geiger 1983 downes and greenstein 1996 bielefeld murdoch and waddell 1997 for example downes and greenstein 1996 focus on demographic and religious characteristics of the surrounding community and its relation to private school location in this paper i use firm level data and focus on potentially important supply side variables tax rates and agglomeration economies most nonprofits are exempt from corporate sales and property taxes hansmann 1987 and gulley and santerre 1993 find evidence that higher corporate property and sales taxes are positively related to nonprofit market share however market share measures obfuscate the dynamics of the industry in terms of entry and exit rates if market share for nonprofits increases in response to higher tax rates this could be because new nonprofits are entering or because for profits are leaving the industry identifying these two cases is impossible with market share data using nonprofit tax return data i examine the relation between these tax exemptions and state county location decisions of new nonprofits to my knowledge this is the first paper to study these interactions at the individual firm level nonprofits also receive tax favored status due to the individual tax deduction on charitable contributions gentry and penrod 1998 employees of and donors to the nonprofits will be affected by the individual tax rates this in turn alters the costs to the nonprofit of location in a high or low tax area unlike previous studies i therefore investigate the relation between individual marginal tax rates and nonprofit location another potential supply side determinant of firm location decisions is the existing firm concentration in the area the potential economies of scale generated by proximity to other firms have been extensively examined in for profit industries 1 previous studies have generally found a positive relation between agglomeration and location carlton 1983 bartik 1985 woodward 1992 gius and frese 2002 rosenthal and strange 2003 to my knowledge bielefeld et al 2004 is the only study that examines nonprofit agglomeration finding evidence of agglomeration in dallas texas this warrants additional examination because nonprofit output is generally service driven and less mobile thus agglomeration implies greater direct competition making market saturation a larger issue in the nonprofit market using a nationwide dataset i examine how location and existing firm concentration are related and explore the potential presence of market saturation i also investigate possible differences between inter and intra industry agglomeration my results provide new insight into nonprofit firm behavior in most cases higher tax rates are associated with new firm location but the results for corporate and property taxes vary across the sample years i find that individual tax rates are an important consideration for nonprofits and are positively correlated to location my analysis also contributes to the literature by examining how the sensitivity to tax rates varies according to the sources of revenues for the institution firms that depend highly on individual donations are more likely to locate in high individual tax states while nonprofits with large mission related revenues are more sensitive to the property tax rate

economic growth regressions for the american states a sensitivity analysis i introduction researchers motivated by a variety of questions turn to data on the economic performance of the american states to analyze their ideas empirically the appeal of cross state empirical analysis derives from the fact that while states differ in relevant dimensions they are not so different as to make omitted variables an overwhelming source of error for example the state economies operate under the same monetary regime the federal reserve comparable legal institutions the u s constitution and borders open to the flow of productive factors knowledge and products cross state analysis avoids the myriad structural differences that encumber cross national empirical analysis thus investigators feel secure in considering a relatively small number of control variables in attempting to establish a statistical relationship between state economic performance and a particular variable of interest the availability of uniform and accurate time series data for the states adds to the appeal of cross state regression models despite the advantages associated with evaluating institutionally similar economies researchers who rely on state regressions find little systematic guidance concerning which variables to include and other basic specification issues for instance do demographic and geographic characteristics vary sufficiently across states to require independent controls do cultural or climatic conditions affect growth or are these variables correlated with other factors that may affect growth such as labor force participation rates or education levels a review of the extensive literature reveals that few studies control for the variables analyzed by other researchers these specification differences make it hard to evaluate and compare the results of existing studies bartik 1991 and phillips and goss 1995 illustrate this problem as they attempt to garner the effect of taxes on state economic development from dozens of studies that employ alternative specifications and methodologies they use meta regression analysis mra to test whether specification changes and alternative variables significantly affect the estimated elasticity of state growth with respect to taxes the mra technique focuses on the sensitivity of the estimated coefficients for state tax variables to model variation in this paper we employ a technique to assess the sensitivity of numerous control variables identified in the state growth literature we also introduce several new control variables the approach identifies which variables are robust to small changes in the conditioning information set our procedure closely follows that in levine and renelt 1992 which for its part relies on the extreme bounds analysis eba suggested by learner 1983 1985 1 the main difference is that we employ annual panel data on the american states pooling cross sectional and time series data whereas levine and renelt employ cross country data averaged over 20 year or even longer time intervals the cross country studies such as those assessed in levine and renelt that average long time periods generally seek to identify factors associated with long run steady state growth the u s state studies using annual panel data do not share a comparable unifying purpose relationships estimated from yearly data reveal short term responses and pick up business cycle effects which confounds drawing implications about growth theory with this qualification in mind the results presented below indicate which variables included in past studies are robust and provide a set of core variables as a starting point for future research that relies on state growth regressions and annual panel data finally the findings demonstrate that several important conclusions in the literature depend on how variables are measured for example the relationship between state growth and government size reverses sign depending on whether we denominate government size in per capita terms or as a share of state income

local economic instability and business location the case of maine this paper investigates the effects of local economic instability on business location in maine instability is represented by the quarterly six month and annual persistence of employment in maine municipalities and seasonal spikes in local employment regression results suggest that businesses are attracted to areas with high short term and seasonal stability but that annual fluctuations in local employment are not a significant deterrent to new business activity services businesses are particularly sensitive to local employment fluctuations presumably because they are often highly integrated into the economy findings suggest that policymakers can jointly pursue the objectives of local economic growth and stability

measuring stochastic technology the case of tulare milk production the flexible moment based approach to production analysis is used to measure the stochastic structure of large scale dairy production in tulare county california this approach is flexible because it does not impose restrictions on the relationships between decision variables and the moments of the probability distribution of output the parameter estimates support the hypothesis that second and third moments are functions of inputs and indicate that capital intensive dairies are riskier the implied behavior of a risk averse dairy manager changed markedly when the effects of inputs on the skewness of the output distribution were included in a decision model

sequential decision making in production models single equation estimates of production models usually are justified by the assumption that production inputs are chosen as part of a one period decision problem yet most production decisions in agriculture are made sequentially in this paper the farmer s optimal input choices are modeled as optimal controls in a stochastic control problem a two period cobb douglas example is used to show that sequential solutions to production problems may yield models which require either single equation or simultaneous equation estimators functional separability stochastic specification and behavior under uncertainty are discussed in the context of dynamic production models

econometric process models for integrated assessment of agricultural production systems this article develops the conceptual and empirical basis for a class of empirical economic production models that can be linked to site specific biophysical models for use in integrated assessment research site specific data are used to estimate econometric production models and these data and models are then incorporated into a simulation model that represents the decision making process of the farmer as a sequence of discrete and continuous land use and input use decisions an econometric process model of the dryland grain production system of the northern plains demonstrates the capabilities of this type of model to simulate decision making both within and outside the range of observed data copyright 2001 oxford university press

a comparison of two methods for estimating income uncertainty with an application to aggregate consumption behaviour econometric theory now provides various techiniques for estimating the variance of a variable for which only a single observation is available at each sample point this paper compares the autoregressive conditional heteroskedastic arch and linear moment lm estimated of the variance of disposable labour income as measures of income uncertainty consumer theory postulates a negative relationship between uncertainty about future income and current consumption using quarterly post world war ii data with income modelled as a random walk with drift both arch and lm estimates of the variance of income are included in a standard specification of the consumption function it is found that while noth the arch and lm estimates of income uncertainty provide essentially the same predicted reduction in consumption growth as uncertainty increases the lm estimates yield a statistically significant influence on consumption while the arch estimated do not however both uncertainty measures provide a statistically

consumption beyond certainty equivalence this paper discusses the recent research on the consumption function that has attempted to relax the assumption of certainty equivalence while there remain many open questions both theoretical and empirical it is clear that the assumption of certainty equivalence can be misleading under more plausible specifications of preferences toward risk uncertainty lowers the level of consumption increases the expected rate of growth of consumption and increases the response of consumption to news about income moreover changes in the amount of uncertainty are a potentially important source of fluctuations in consumption this abstract was borrowed from another version of this item

estimates of the variance of u s inflation based upon the arch model it is generally agreed that the unpredictability of future inflation is a major component of the welfare loss associated with inflation perfectly predicted inflation might induce some costs through institutional rigidities governmental interference and transaction costs but in the long run these should be rather minimal as these institutions adopt various forms of indexing when inflation is unpredictable risk averse economic agents will incur a loss even if prices and quantities are perfectly flexible in all markets inflation is a measure of the relative price of goods today and goods tomorrow thus uncertainty in tomorrow s price impairs the efficiency of today s allocation decisions friedman in his nobel lecture 8 argues convincingly that higher variability of inflation would lead to decreased output ceteris paribus he then conjectures that higher rates of inflation are generally associated with higher variability of inflation and presumably greater uncertainty about future rates if this is true then higher rates of inflation would also be associated with low levels of output which implies a positively sloped phillips curve this paper uses a new statistical technique arch to estimate the conditional mean and variance of inflation from u s time series data the main finding is that the variance of inflation in the seventies was only slightly greater than in the sixties

intra national home bias some explanations wolf demonstrates that trade within the united states appears substantially impeded by state borders we revisit this finding with improved data we show that much intranational home bias can be explained by wholesaling activity shipments by wholesalers are much more localized within states than shipments from manufacturing establishments controlling for relative prices and the use of actual rather than imputed shipment distances also reduces home bias estimates

the effect of state and local taxes on economic growth a time series cross section approach results based on pooled time series and cross section data are presented which indicate that state and local tax increases significantly retard economic growth when the revenue is used to fund transfer payments however when the revenue is used instead to finance improved public services such as education highways and public health and safety the favorable impact on location and production decisions provided by the enhanced services may more than counterbalance the disincentive effects of the associated taxes these findings underscore the importance of considering the incentives provided by a state s expenditures as well as by its taxes i n the past several years a number of states have implemented limitations on taxes or expenditures while others have raised tax rates in response to the revenue shortfalls of the early 1980s although much of the ongoing debate over state fiscal structures revolves around expressed preferences over tax expenditure combinations per se the question of how state and local taxes may affect economic growth is often central to the discussion nonetheless the empirical evidence remains sparse previous studies can be divided into two broad categories assessments of the magnitudes of tax costs and statistical analyses of the relationship between tax rates and growth cost studies have tended to minimize the role of taxes in business location decisions either because state and local taxes are a relatively small component of total costs for most businesses or because interstate tax differences are small relative to other cost differences between states although these results suggest that the role played by taxes is a minor one describing how large the tax disparities may be is not the same as ascertaining their economic effect of the statistical studies many including bloom 1955 thompson and mattila 1959 and carlton 1979 1983 find no relationship between taxes and growth however kleine 1977 grieson 1980 and generally grieson et al 1977 report negative correlations romans and subrahmanyam 1979 find growth to be negatively related to the fraction of revenues devoted to transfer payments and a variable which they claim measures personal tax progressivity but positively related to business taxes with the exception of carlton who estimates models of the birth and size of firms within metropolitan areas and the grieson et al 1977 and grieson 1980 studies which consider taxes in new york city and philadelphia these authors use data from a single cross section of states more recently newman 1983 and plaut and pluta 1983 both use cross sectional data from two time periods the former finding negative effects of corporate tax rates and the latter yielding mixed results in this study we utilize a time series from 1965 through 1979 of cross sections of 48 states exploiting the richness of this data set we are able to allow for otherwise unexplained differences between states which could be expected to bias results based on a single cross section moreover this much larger sample provides the statistical power necessary to disentangle the separate effects of different categories of taxes public expenditures and transfer payments a distinguishing feature of this paper is that we explicitly recognize the government budget constraint linking these fiscal variables and the deficit or surplus in addition we have taken account of the effects of labor force characteristics by including variables for wage rates unionization and population density our results indicate that tax increases significantly retard economic growth when the revenue is used to fund transfer payments as a result programs of income redistribution are more effectively undertaken at the federal than at the state and local level on the other hand when the revenue is received for publication april 30

the story of the moment risk averse cypriot farmers respond to drought management this article illustrates the importance of estimating risk preferences when evaluating water policy using agricultural production data from the kiti region of cyprus we estimate farmers risk preferences a la antle journal of business and economic statistics 1 192 201 1983 american journal of agricultural economics 69 509 22 1987 and show sensitivity to higher order moments of profit such as skewness we show that farmers in the kiti region are risk averse with risk premiums in the region of 20 of expected profit we use these estimates to analyse the impact of a water quota from the perspective of three policy makers who differ only in their understanding of farmers risk preferences we show in the case of kiti that policy makers who model risk preferences incorrectly that is either a assume risk neutrality or b ignore down side risk wrongly predict the magnitude and direction of input responses and therefore the magnitude of welfare changes this highlights the importance of accomm

industry migration and growth in the south for at least the last two decades the south and southwest have been the fastest growing regions in the united states during this period we have witnessed considerable shifts in the location of economic activity and overall the movement has been decidedly toward the south since the early sixties when this southern migration began to accelerate an increasing amount of public attention has been directed to this topic so much so that it is now popularly referred to as the sunbelt phenomenon numerous explanations have been advanced to account for this rapid growth in the south but three explanations have persistently evoked an impressive level of debate first many have argued that a significant portion of this regional redistribution can be attributed to differentials in state and local taxing policies in particular the state corporate income tax these rates vary considerably across states but even more important is the observation that there have been significant changes in the structure of corporate taxes over the last few decades beginning in the early 1950s the relative tax rate for several southern states particularly those in the east south central and west south central divisions began to decline sharply on the other hand relative tax rates for three divisions new england the east north central and the midatlantic rose in the early sixties by 1970 the relative tax rate ranged from 0 60 in the west south central down from 1 20 in 1950 to 1 37 in the mid atlantic up from 1 15 in 1950 notwithstanding these stylized facts the consensus from previous empirical work on industry location suggests that state taxes have not influenced the direction or magnitude of industry migration however there are reasons to believe that acceptance of this conclusion may be premature for example in the early body of work results were based on simple correlations of tax levels and changes in either value added or employment 2 more recent attempts to empirically model corporate tax effects have arrived at somewhat ambiguous results carlton 1977 examining three 4 digit industries found that corporate tax differentials failed to explain any of the variation in new births of firms across smsas hodge 1979 while confirming carlton s results for the same industries discovered that taxes have significantly affected regional investment patterns in another industry not covered in carlton s study 3 why taxes mattered in one industry and not in the other three remained a matter of ad hoc speculation a second explanation alleges that states in the south have begun to exhibit a more favorable business climate although it is difficult to measure directly a state s business climate one important manifestation of that climate is its position with respect to the division of power between union and management in the collective bargaining process legal obstacles to union organization and bargaining power will be viewed by firms as a positive signal of a pro business environment the creation of legislative obstareceived for publication october 29 1981 revision accepted for publication april 16 1982 miami university the author is especially indebted to michael ward at the rand corporation for numerouls helpful discussions throughout the preparation of this study also the author benefited from the advice and comments of john antel robert cotterman lee lillard john lunn william j moore james smith finis welch and two referees of this review financial suppoi t was provided by the foundation for research in economics and education at ucla and the university of british columbia humanities and social sciences committee i the relative tax is defined as a state s tax rate divided by the average for all states as in most economic discussions it is relative price that matters 2 for a review of earlier work see due 1961 some of the studies reviewed include bloom 1955 campbell 1958 floyd 1952 and larson 1957 see also garwood 1952 3 most of the other empirical work focused exclusively on intt urban location decisions and hence had no reason to examine state corporate taxes however they found local tax differentials inter zonal were unimportant in determining intra urban movement for example see moses and williamson 1967 and schmenner 1978

global price dispersion are prices converging or diverging abstract this paper documents significant time variation in the degree of global price convergence over the last fifteen years in particular there appears to be a general u shaped pattern with price dispersion first falling and then rising in recent years a pattern which is remarkably robust across country groupings and commodity groups this time variation is difficult to explain in terms of the standard gravity equation variables common in the literature as these tend not to vary much over time or have not risen in recent years however regression analysis indicates that this time varying pattern coincides well with oil price fluctuations which are clearly time varying and have risen substantially since the late 1990s as a result this paper offers new evidence on the role of transportation costs in driving international price dispersion
