structural changes in volatility and stock market development evidence for spain abstract in this paper we review the factors that lead to changes in stock market volatility and use alternative methodologies of endogenous breakpoint detection in order to analyze whether the volatility of the spanish stock market has changed significantly over the period 1941 2001 this period corresponds to years of profound development of both the financial and the productive sides of the economy in this country the analysis of the spanish stock market suggests that volatility has behaved in a different manner over the period 1941 2001 after three decades of low volatility a structural break in volatility is detected in 1972 coinciding with the opening of the spanish economy from 1972 to 2001 the years of more intense financial development the stock market presents a higher level of volatility and lower persistence this effect is partly attributable to the increased growth of trading volume brought about by the economic development process

do merging local governments free ride on their counterparts when facing boundary reform the western world exhibited a significant trend towards larger local governments in the twentieth century which was driven to a large extent by boundary reforms boundary reforms can provide economic benefits but may also give rise to costs driven by opportunistic political behavior this study uses a swedish compulsory reform to test for such behavior the reform gives a local government the incentive to accumulate debt before a merger takes place since the taxpayers in the new locality will share the cost the strength of the incentive to free ride is determined by the population size of the initial locality relative to that of the new locality i find an economically large and statistically significant free riding effect

politics and efficiency of separating capital and ordinary government budgets we analyze a golden rule that separates capital and ordinary account budgets and allows a government to finance only capital items with debt many national governments followed this rule in the eighteenth and nineteenth centuries and most u s states do today we study an overlapping generations economy where majorities choose durable and nondurable public goods in each period when demographics imply even moderate departures from ricardian equivalence the golden rule substantially improves efficiency examples calibrated to u s demographics show greater improvements at the state level or with nineteenth century demographics than under current national demographics

deviations from purchasing power parity in the long run this paper demonstrates that deviations from purchasing power parity reveal a remarkable and possibly startling consistency with martingale behavior during both fixed and flexible rate periods for a wide variety of countries and in both monthly and annual data since this pattern appears to be much more general than one would expect on the basis of models founded on international commodity arbitrage the paper proposes an alternative explanation which instead relies on financial arbitrage in bonds as the underlying mechanism this paper will demonstrate that deviations from purchasing power parity ppp reveal a remarkable and possibly startling consistency with martingale behavior during both fixed and flexible exchange rate periods for a wide variety of countries and in both monthly and annual data this pattern appears to be much more general than one would expect on the basis of models founded on international commodity arbitrage the paper therefore proposes an alternative explanation which does not presuppose free trade in goods but which instead relies on financial arbitrage in bonds as the underlying mechanism the major implication of the theory and the results is that ppp is as likely to be violated in the long as in the short run as an empirical matter deviations from ppp can be observed for most currencies at any instant see kravis et al 21 stockman 37 and genberg 15 among others these deviations are typically both cumulative and persistent the real exchange rate can remain on either side of parity for lengthy but variable time intervals of a year or more as a consequence the current consensus shared

optimal liberalization of financial markets abstract as financial markets become completely liberalized countries gain from improved risk sharing but less wealthy countries can no longer profit from borrowing abroad at the lower rate and reinvesting at home at the higher rate with decreasing rather than constant returns to capital the gain from risk sharing is more likely to dominate the loss of the difference between the borrowing rate abroad and the decreasing reinvestment rate at home complete liberalization is likely to be optimal for less wealthy countries unless their labor endowment is large their productivity is large or holdings by foreigners are small as in china

oil prices and the stock prices of alternative energy companies energy security issues coupled with increased concern over the natural environment are driving factors behind oil price movements while it is widely accepted that rising oil prices are good for the financial performance of alternative energy companies there has been relatively little statistical work done to measure just how sensitive the financial performance of alternative energy companies are to changes in oil prices in this paper a four variable vector autoregression model is developed and estimated in order to investigate the empirical relationship between alternative energy stock prices technology stock prices oil prices and interest rates our results show technology stock prices and oil prices each individually granger cause the stock prices of alternative energy companies simulation results show that a shock to technology stock prices has a larger impact on alternative energy stock prices than does a shock to oil prices these results should be of use to investors managers and policy makers

the demand for education with power equalizing aid abstract state grants in aid modify the full fiscal income and tax price for education services faced by voters in local school districts if aid is non linear in the local property tax rate as occurs with district power equalization coupled with an aid floor then individual budget constraints are non linear and least squares estimation is inappropriate we develop and estimate a model that incorporates these effects derive and extensively illustrate the comparative statics present global and local elasticities and simulate the impact of parameter changes on the variance of spending and the cost of the program

technological innovation and real investment booms and busts abstract we investigate why new high risk technologies can attract excessive and often unprofitable investment we develop an equilibrium model in which rational risk averse agents overinvest in a risky technology possibly to the point that its expected return is negative overinvestment results from relative wealth concerns which arise endogenously from the imperfect tradability of future endowments competition over future consumption leads to an indirect utility for wealth with keeping up with the joneses properties that can induce herding because overinvestment increases with the risk of the technology our model can explain why new risky technological innovations may promote investment bubbles

deviations from purchasing power parity and capital flows abstract this article examines the implications of deviations from purchasing power parity ppp for an investor s portfolio decision and the consequent capital flows in a two country intertemporal model with complete financial markets in the presence of deviations form ppp investors from different nations hold disparate portfolios and the equilibrium that results is not a pooling one we solve eplicitly for asset demands and derive the relationship between the direction of capital flows and deviations from ppp in contrast to the small country assumption in the existing literature the world interest rate in this model is determined endogenously

the collapse of purchasing power parities during the 1970 s one of the striking facts concerning the relationship beiveen prices and exchange rates during the 1970 s has been the dismal performance of the predictions of the simple versions of the purchasing power parity doctrine ppp that doctrine in its absolute version states that the equilibrium exchange rate between domestic and foreign currencies equals the ratio of domestic to foreign price levels the relative version of the doctrine relates equilibrium changes in exchange rates to changes in the ratio of domestic to foreign prices during the 1970 s short run changes in exchange rates bore little relationship to short run differentials in national inflation rates and frequently divergences from purchasing power parities have been cumulative this paper reviews and analyzes the empirical record of exchange rates and prices during the 1970 s and the analysis is based on the experience of the dollar pound the dollar frecch franc and the dollar dm exchange rates section 2 presents the evidence on ppp during the 1970 s and contrasts it with the evidence from the 1920 s a period during which the doctrine held up reasonably well this analysis is relevant for assessing whether the flexible exchange rate system was successful in providing national economies with an added degree of insulation from foreign shocks and whether it provided policymakers with an added instrument for the conduct of macroeconomic policy the evidence regarding devia tions from purchasing power parities is also relevant for determining whether there is a case for managed float section 3 attempts to explain what went wrong with

capital mobility and the current account abstract this paper analyzes the effect of unanticipated changes in the terms of trade on consumption expenditures and the current account in a small open economy simple formulas are obtained for the covariances of changes in consumption expenditures the current account and the expected current account with changes in the terms of trade it is shown that if investment is uncorrelated with the terms of trade a necessary condition for unanticipated changes in the terms of trade to be correlated with changes in consumption expenditures and the expected current account is that the real expected return on foreign bonds differs from the real expected return on domestic bonds

an intertemporal model of international capital market segmentation this paper develops an intertemporal model of international capital market segmentation within the model under various forms of segmentation integration the equilibrium asset prices and allocations the risk free interest rate and the intertemporal consumption behavior and welfares of two countries are derived and compared it is shown that the equilibrium interest rate is increased on integration and that integrating markets may be significantly welfare decreasing for one of the countries conditions that may lead to a decrease in welfare are investigated the conclusions as to the effects of segmentation on asset prices in the mean variance model of the existing finance segmentation literature are also shown to break down in an intertemporal model

parochial interests and the centralized provision of local public goods evidence from congressional voting on transportation projects abstract local public goods financed from a national tax base provide concentrated benefits to recipient jurisdictions but disperse costs creating incentives for legislators to increase own district spending but to restrain aggregate spending due to the associated tax costs while these common pool incentives underpin a variety of theoretical analyses which tend to predict inefficiencies in the allocation of public goods there is little direct evidence that individual legislators respond to such incentives to test for reactions to such incentives this paper analyzes 1998 congressional votes over transportation project funding the empirical results provide evidence that legislators respond to common pool incentives the probability of supporting the projects is increasing in own district spending and decreasing in the tax burden associated with aggregate spending having found that legislators do respond to such incentives i use the parameter estimates to calculate the efficient level of public goods which suggest over spending in aggregate especially in politically powerful districts and large associated deadweight loss

communication in federal politics universalism policy uniformity and the optimal allocation of fiscal authority the paper presents a positive model of policy formation in federal legislatures when delegates engage in the strategic exchange of policy relevant information depending on the type of policy under consideration communication between delegates generally suffers from a bias that makes truthful communication difficult and sometimes impossible this generates inefficient federal policy choices that are often endogenously characterized by overspending universalism and uniformity building on these findings i develop a theory of fiscal de centralization which revisits the work of oates in a world of incomplete information and strategic communication empirical results from a cross section of us municipalities are consistent with the predicted pattern of spending

technological change and the stock market tobin s average q has usually been well above 1 but fell below 1 during 1974 1984 our model explains this pattern and reconciles it with unchanging aggregate investment the stock market value in the numerator of q reflects ownership of physical capital and knowledge but the denominator measures just physical capital therefore q is usually above 1 periodic arrivals of important new technologies such as the microprocessor in the 1970 s suddenly render old knowledge and capital obsolete causing the stock market to drop national accounts measures of physical capital miss this rapid obsolescence then q appears to drop below 1 jel e44 o3 o41

aggregate spending and the terms of trade is there a laursen metzler effect this paper investigates the spending and current account effects of terms of trade shifts in a model where households maximize utility over an infinite planning period in the framework developed here an economy specialized in production must experience a fall in aggregate spending and a current surplus as a result of an unanticipated permanent worsening in its terms of trade the paper s model thus provides a setting in which the current account deficit predicted by laursen and metzier harberger and others fails to materialize

international good market segmentation and financial innovation abstract while international capital flows are now well liberalized markets for goods remain segmented to investigate how financial innovation may relieve the effects of this segmentation on risk sharing we examine a series of two country economies with internationally segmented good markets distinguished by the available financial securities sufficient conditions for efficiency include complete international financial markets together with liberalized international financial flows under these conditions heterogeneous agents from the same country may use securities as a substitute for the international shipment of goods this allows them to partially circumvent the segmentation allowing for efficient risk sharing

cross border externalities and cooperation among representative democracies abstract this paper analyzes the provision of public goods with cross border externalities by representative democracies the level of provision of each country is decided by a policy maker elected by majority rule at the country level we compare the case in which policy makers set their policies noncooperatively with the case in which they set their policies through coasian cooperation cooperation induces policy makers to internalize cross border externalities but it also induces strategic voters to elect a policy maker who cares less about the public good to reduce their public good contribution the former effect increases public good provision while the latter reduces it we show that once voters incentives are taken into account whether cooperation is beneficial depends neither on voters preferences nor on the magnitude of spillovers nor on the size bargaining power or efficiency of each country instead it depends only on the curvature of the demand for the public good cooperation increases decreases public good provision when the demand function is more less convex than the unit elastic demand function hence the desirability of international cooperation depends mostly on the type of public good considered

demand for environmental goods evidence from voting patterns on california initiatives this article studies voting behavior on 16 environmental ballot propositions in california in order to characterize the demand for environmental goods the environment is found to be a normal good for people with mean incomes but some environmental goods are inferior for those with high incomes at least when supplied collectively an important price of environmental goods is reduced income in the construction farming forestry and manufacturing industries income and price can explain most of the variation in voting there is little need to introduce preference variables such as political ideology

on the effects of barriers to international investment a simple model is presented in which it is costly for domestic investors to hold foreign assets the implications of the model for the composition of optimal portfolios at home and abroad are derived it is shown that all foreign assets with a beta larger than some beta plot on either one of two security market lines some foreign assets with a beta smaller than are not held by domestic investors even if their expected return is increased slightly while it is obviously not true that asset markets are completely segmented between countries there is evidence of barriers to international investment although reality seems to lie in that grey area between complete segmentation and no segmentation at all most international asset pricing models are concerned with the extreme case of no barriers to international investment no effort seems to have been made to study the effect on portfolio choice of such barriers which make it costly to hold foreign securities as opposed to domestic securities but which do not in general render international diversification so onerous that investors avoid foreign securities completely casual empiricism suggests that models without barriers to international investment should be suspect those models cannot explain why it appears that in every country investors on average hold more domestic securities than would be required if they held the world market portfolio 2 this paper constructs a model of international asset pricing in which there is a cost associated with holding either long or short risky foreign securities for the sake of simplicity in most of the paper we assume that while domestic investors face barriers to international investment foreign investors face no such barriers it turns out that nothing significant is lost with such an assumption the main conclusions of this paper for the case in which foreign investors face no barriers to international investment are 1 in the presence of barriers to international investment some risky foreign

budgetary reform and formal modeling a comment on gabel and hager in a recent article gabel and hager argue that the line itemveto and the balanced budget amendment promote bba and mayincrease pork barrel spending in their discussion of thebalanced budget amendment gabel and hager present one exampleto support their claim i demonstrate that the effect of a bbain their model is highly contingent on parameter values andthat their results hold only for a specific set of parametervalues further in a generalized model where the balancedbudget amendment is crafted endogenously the bba that isenacted has the effect of either decreasing spending orkeeping it constant

the terms of trade and the current account the harberger laursen metzler effect the paper examines the effect of terms of trade changes on a small country s spending and current account assuming optimizing behavior in an intertemporal framework with perfect international capital mobility a temporary future terms of trade deterioration implies a deterioration improvement of the trade balance whereas a permanent terms of trade deterioration has an ambiguous effect depending on the rate of time preference nominal and real variables are considered via exact price indexes two periods and an infinite horizon are examined

current account dynamics and the terms of trade harberger laursen metzler two generations later this is a study of the current account dynamics resulting from the savings and investment dynamics in a small open economy which is subject to exogenous changes in its terms of trade and in world interest rates anticipated and unanticipated as well as temporary and permanent terms of trade changes have very different effects there is however a general tendency towards cycles in both savings and investment which gives rise to cycles in the current account it is shown that the classic harberger laursen metzler effect on saving of a terms of trade deterioration can have any sign for plausible parameter values both for temporary and permanent disturbances

estimating school district expenditure functions under conditions of closed end matching aid abstract several studies have used ordinary least squares ols to estimate school district expenditure functions for states with closed end matching aid the present paper demonstrates that the estimates of these studies may be inconsistent a two stage technique which guarantees consistent estimates is described and is used to estimate the price elasticity of expenditure for pennsylvania school districts the two stage estimates indicate expenditure to be substantially more price elastic than do the ols estimates the two stage technique is appropriate for estimating any input demand or expenditure function when closed end matching aid is involved

toward a comprehensive model of welfare exits the case of afdc pressures to reform the welfare system in the united states give rise to a need for improved information about individual welfare recipients using data from the survey of income and program participation and event history analysis this paper profiles the probabilistic tendencies of conditions associated with welfare exits the joint influences of policy economic conditions and individual circumstances and characteristics are considered in an attempt to build a comprehensive model of program turnover

special interest groups and the allocation of public funds i propose a fully rational model of government contracting that explains differences in local government spending from grants and other income in this model violations of fungibility arise from dynamic interactions between politicians and interest groups with the ability to raise funds for the local government the predictions of the model are tested by exploiting unique features of windfalls received by states under a settlement with the tobacco industry although windfalls are legally unrestricted the median state increased spending on tobacco control programs from zero to 2 30 per capita upon receipt of funds the marginal propensity to spend on such programs is 0 20 from settlement revenue and zero from overall income states which were not involved in the settlement lawsuits spend less these results cannot be explained by existing models in the literature

local public expenditure in sweden a model where the median voter is not necessarily decisive abstract this paper deals with local public expenditures and the analysis is based on cross section data for the swedish municipalities two models are estimated one is the basic median voter model where the decisive voter is assumed to be the voter with median income while the other is a more general statistical alternative the statistical alternative nests the basic median voter model as a special case which makes it easy to test the null hypothesis that the basic median voter model is the correct model given that the alternative is the true general structure although our results indicate a rejection of the null hypothesis the estimation results are nevertheless similar for the two models

the politics and economics of pork barrel spending the case of federal financing of water resources development this paper empirically investigates the economic and political factors that have influenced annual corps of engineers water resource spending despite the common view that pork barrel spending is economically unjustified and purely politically motivated economic factors have been important in determining water resource spending from 1865 1920 economic development and industrialization increase spending and from 1921 1988 spending appears to be counter cyclical there is also evidence that majority parties control spending levels in the post civil war period while in recent times legislators act under a norm of constrained universalism and are influenced by the costs to their constituents of increased spending

changing the price of pork the impact of local cost sharing on legislators demands for distributive public goods abstract the provision of public services through national legislatures gives legislators the chance to fund locally beneficial public projects using a shared national tax base nationally financed and provided local congestible public goods will be purchased at a subsidized price below marginal cost and may be inefficiently too large as a consequence an important assumption behind this inefficiency is that national legislators in fact demand more of the locally beneficial project as the local price for projects declines this paper provides the first direct test of this important assumption using legislators project choices following the passage of the water resources development act of 1986 wrda 86 we find legislators chosen water project sizes do fall as the local cost share rises with a price elasticity of demand ranging from 0 81 for flood control and shoreline protection projects to 2 55 for large navigation projects the requirement of wrda 86 that local taxpayers contribute a greater share to the funding of local water projects reduced overall proposed project spending in our sample by 35 and the federal outlay for proposed project spending by 48

the effects of lottery prizes on winners and their neighbors evidence from the dutch postcode lottery each week the dutch postcode lottery pcl randomly selects a postal code and distributes cash and a new bmw to lottery participants in that code we study the effects of these shocks on lottery winners and their neighbors consistent with the life cycle hypothesis the effects on winners consumption are largely confined to cars and other durables consistent with the theory of in kind transfers the vast majority of bmw winners liquidate their bmws we do however detect substantial social effects of lottery winnings pcl nonparticipants who live next door to winners have significantly higher levels of car consumption than other nonparticipants

the econometrics of piecewise linear budget constraints a survey and exposition of the maximum likelihood method in this article maximum likelihood techniques for estimating consumer demand functions when budget constraints are piecewise linear are exposited and surveyed consumer demand functions are formally derived under such constraints and it is shown that the functions are themselves nonlinear as a result the econometric problems in estimating such functions are exposited and the importance of the stochastic specification is stressed in particular the specification of both unobserved heterogeneity of preferences and measurement error econometric issues in estimation and testing are discussed and the results of the studies that have been conducted to date are surveyed

geographical redistribution with disproportional representation a politico economic model of norwegian road projects politicians bias public policies to favor particular election districts according to the traditional common pool model districts facing low tax shares should receive relatively large government projects we suggest a swing voter model where the number of voters on the ideological cut point lack of party identification and number of district representatives per voter determine project sizes we analyze the allocation of state road investments in norway from 1973 1997 exploiting unique data on characteristics of voters legislative representation and tax prices in 19 election districts geographical representation to parliament is biased mostly due to an ancient constitution shares of swing voters and legislative over representation lead to higher levels of road investments while high levels of party identification reduce investments

female labor supply with a discontinuous nonconvex budget constraint incorporation of a part time full time wage differential this paper incorporates the well documented part time full time wage differential into an empirical labor supply model with both a heterogeneity and a random error term and estimates that model fo

the political economy of benefits and costs a neoclassical approach to distributive politics this essay offers a rational political explanation for the notorious inefficiency of pork barrel projects with an optimization model of legislative behavior and legislative institutions the model emphasizes the economically arbitrary from a welfare point of view importance of the geographic incidence of benefits and costs owing to the geographic basis for political representation we explore the implications of a legislator s objective function and derive conditions under which a representative legislature will select an omnibus of projects each of which exceeds the efficient scale

public spending and the paradox of supermajority rule this article examines the paradox that a supermajority rule in a legislature promotes excessive government spending we propose a simple conjecture if rent seeking coalitions dominate legislative politics and if individual legislators demands for rent seeking activities are price inelastic a change of legislative rules from simple majority to a supermajority will lead to greater public spending other things equal using data from u s state legislatures 1970 to 2007 we find that the adoption of a supermajority rule has a robust positive impact on various types of tax revenues and government expenditures

deviations from constituent interests the role of legislative structure and political parties in the states this paper investigates the determinants of state spending over 1960 1990 recent empirical studies suggest that state government expenditure is greater than the electorate desires our main finding is that expenditure was positively related to the number of seats in a state s legislature this is consistent with the hypothesis that logrolling leads representatives to spend more than their constituents would like we also find that political parties do not have a pronounced effect on overall levels of expenditure but do influence the composition of spending in particular democratic control of state government is associated with higher levels of welfare spending

legislative representation bargaining power and the distribution of federal funds evidence from the us congress this article investigates the relationship between representation in legislatures and the geographic distribution of federal funds in a legislative bargaining model we demonstrate that funds are concentrated in high representation areas and two channels underlie this result the proposal power channel reflects the role of representation in committee assignments and the vote cost channel reflects the role of representation in coalition formation in our empirical analysis we find that small states relative to large states receive more funding in the us senate relative to the house we also find empirical support for the two channels underlying this relationship throughout the history of federations and international organisations a key consti tutional design question involves how jurisdictions of different sizes are represented in legislative bodies and how their votes will ultimately be weighted large jurisdictions typically argue for delegation sizes or voting weights that are roughly proportional to population whereas small jurisdictions typically argue for an equal number of delegates or votes for each jurisdiction this conflict over representation is presumably driven at least in part by a belief that increased representation strengthens bargaining power in the battle over the geographic distribution of funds authorised by these legislative bodies in this article i analyse the relationship between legislative representation bar gaining power and the geographic distribution of federal funds from both a theoretical and empirical perspective in addition to investigating the existence of a relationship between representation and federal funds i also explore the underlying mechanisms that is i ask which political institutions such as agenda control provided to commit tees and the formation of coalitions under majority rule shape the bargaining power of jurisdictions in central legislatures and thus facilitate the relationship between repre sentation and the distribution of federal spending to provide a framework for analysing these issues i begin by developing a simple theoretical model of a central legislature that determines the crossjurisdiction distri bution of local public goods which are financed by a national tax base both delegation sizes and population are variable allowing me to consider a variety of institutional arrangements for jurisdictional representation legislators represent local interests and given the common pool problem associated with concentrated benefits and dis persed tax costs attempt to increase ownjurisdiction spending but to restrain spending elsewhere the model follows a recent literature on legislative bargaining in which a proposer must secure a majority of votes in order to pass legislation and due to the

sticky goods prices flexible asset prices monopolistic competition and monetary policy a monetary general equilibrium asset pricing model with sticky goods prices is developed goods prices are set by monopolistically competitive firms that maximize stock market value equilibria with underutilization of resources excess capacity in some states result in contrast to previous monetary asset pricing models the degree of competition affects capacity utilization monetary policy can affect output and resource utilization in addition to real asset prices depending upon the amount of information available to the monetary authority

the information technology revolution and the stock market evidence since 1968 the ratio of stock market capitalization to gdp has varied by a factor of 5 in 1972 the ratio stood at above unity but by 1974 it had fallen to 0 45 where it stayed for the next decade it then began a steady climb and today it stands above 2 we argue that the it revolution was behind this and moreover that the capitalization gdp ratio is likely to decline and then rise after any major technological shift the three assumptions that deliver the result are

fiscal effects of the voter initiative in the first half of the twentieth century abstract this paper compares the fiscal policy of initiative and noninitiative states in the first half of the twentieth century states with initiatives had higher combined state and local expenditure after controlling for income and other demographics but a lower ratio of state to local expenditure this together with existing evidence from later in the century suggests that the voter initiative does not have a consistent effect on the overall size of state and local government however it does systematically lead to more decentralized expenditure

dynamics of biofuel stock prices a bayesian approach we use bayesian markov chain monte carlo methods to investigate the linkage between the volatility of ethanol security prices and the uncertainty surrounding the profitability of ethanol production and the price variations of non ethanol energy securities the joint evolution of return and volatility is modeled as a stochastic process that incorporates jumps in both return and volatility while a strong and significant correlation is found between the volatility of ethanol securities and profit uncertainty from june 2005 to july 2008 the dynamic pattern of ethanol stock volatility is strikingly similar to that of the s p 500 energy sector index in the more recent period our evidence lends support to the findings in the literature on rational learning from uncertainty in determining the equity price and volatility during the adoption and development of a technological innovation

residential demand for electricity under inverted block rates evidence from a controlled experiment block rate structures are used extensively in public utility pricing including residential electricity estimating price elasticities in this context is complicated by the resulting nonlinearity of the consumer s budget constraint this article estimates the demand for electricity under inverted block rates using data from a residential rate experiment the study provides an opportunity to obtain short run price elasticities in an experimental setting and to compare alternative estimators developed for nonlinear budget constraints elasticities of demand with respect to individual components of the block rate are developed using a modification of the structural maximum likelihood estimator

the decline of welfare benefits in the u s the role of wage inequality welfare benefits in the u s have experienced a much studied secular decline since the mid 1970s we explore a new hypothesis for this decline related to the increase in wage inequality in the labor market and the decline of real wages at the bottom of the distribution we posit that voters prefer benefits which are tied to low skilled wages we test the hypothesis using a 1969 1992 panel of state level data an additional contribution of our analysis is the use of general social survey data on voter preferences for welfare which we combine with current population survey data to determine the voter in each state who has the median preferred welfare benefit level our analysis reveals considerable evidence in support of a role for declining real wages in the decline of welfare benefits

the impact of congestion on local public good production abstract this paper models local public goods production where allocation of the publicly provided input occurs simultaneously with production of the final service output the framework models local public goods as developed in club theory where congestion is an increasing function of population central to identification of the model is that the quantities of the input police are differentiated from the produced output safety estimation is across neighborhoods within a single city the results show there is a very low elasticity of congestion on average but safety in some neighborhoods in more congested than private goods

legislative organization and government spending cross country evidence abstract the law of 1 n posits that an increase in the number of elected representatives fuels excessive government spending despite its wide acceptance as a stylized fact the law of 1 n has received only limited empirical scrutiny and the existing evidence for the american states provides mixed support for the thesis this paper examines the law of 1 n in bicameral and unicameral legislative structures using a cross section of democratic countries the results indicate that legislative size matters under both legislature structures but bicameralism dampens the 1 n effect relative to unicameralism

a bureaucratic theory of flypaper effects abstract one well documented pattern in local public finance is that in comparison with what is spent out of residents private income a disproportionate amount of lump sum intergovernmental aid is used to increase expenditures rather than to reduce local taxes this paper shows how a bureaucratic model of the type suggested by niskanen bureaucracy and representative government aldine atherton chicago 1971 can be used to explain this behavior an empirical test of the model using 115 small governments in michigan suggests that this bureaucratic model explains capital expenditures well while operating expenditures appear to be better explained by the standard median voter model

the effects of grants in aid on state and local expenditures abstract this paper develops econometric methods to estimate the effect of the piecewise linear budget constraints created by grant formulas in which the subsidy rate is not constant over expenditures e g closed end grants the methods are applied to the afdc program the results show that because of the kinked nature of the grant formula 1 the present federal formula actually increases cross state inequality in afdc benefits 2 several subsidy rates in the formula actually reduce benefits and 3 the so called flypaper effect disappears

real interest rates home goods and optimal external borrowing the paper investigates the optimal time path of consumption and external borrowing in the dependent economy model the small country faces given world prices and a given world real interest rate the presence of a home goods sector implies that the relevant real interest rate appropriate to consumption decisions depends on the rate of change of the real price of home goods the paper shows how transitory disturbances in output or in the world real interest rate affect the time profile of consumption and the trade balance in particular it is shown that the presence of a home goods sector dampens the consumption effects of changes in the world interest rate

supermajority rule and bicameral bargaining this paper revisits the claim that supermajority rules and bicameral legislative structures restrain excessive government spending and taxation our analysis suggests that the extension effect of a supermajority rule that requires logrolling across additional members increases with the ratio of seats in the house relative to seats in the senate using a panel of us states 1970 2008 we find that the ratio of house to senate seats has a robust positive impact on the tendency of a supermajority rule to inflate the budget our finding implies that a supermajority rule can have a perverse effect on budget outcomes in bicameral legislatures owing to two factors the geographic overlap between chambers and the low price elasticity of demand for public goods

a model of exchange rate dynamics this model treats the exchange rate as an asset price that depends on expectations concerning exogenous real and monetary factors that will affect relative prices and absolute price levels in future periods changes in exchange rates reflect both expected changes in these exogenous factors and changes in expectations occasioned by new information the model explains the random component in exchange rate behavior the source of divergences from purchasing power parity the anticipatory response of exchange rates to future expected disturbances and the causes of exchange rate overshooting

does innovation cause stock market runups evidence from the great crash this article examines the stock market s changing valuation of corporate patentable assets between 1910 and 1939 it shows that the value of knowl edge capital increased significantly during the 1920s compared to the 1910s as investors responded to the quality of technological inventions innovation was an important driver of the late 1920s stock market runup and the great crash did not reflect a significant revaluation of knowledge capital relative to physical capital although substantial quantities of influential patents were accumulated during the post crash recovery high technology firms did not earn significant excess returns over low technology firms for most of the 1930s

international risk sharing and capital mobility abstract under certain assumptions pareto efficient risk sharing implies that changes in consumption across nations will be perfectly correlated this result leads to an indicator of the welfare loss due to imperfect sharing of consumption risks across nations this indicator is used to evaluate the welfare implications of restrictions on various components of the international capital flow holding constant other components of the flow and domestic investment we find that variability in national consumption growth rates would have been considerably greater if capital flows had been restricted and that welfare would have been reduced significantly

simulated likelihood estimation of diffusions with an application to exchange rate dynamics in incomplete markets abstract we present an econometric method for estimating the parameters of a diffusion model from discretely sampled data the estimator is transparent adaptive and inherits the asymptotic properties of the generally unattainable maximum likelihood estimator we use this method to estimate a new continuous time model of the joint dynamics of interest rates in two countries and the exchange rate between the two currencies the model allows financial markets to be incomplete and specifies the degree of incompleteness as a stochastic process our empirical results offer several new insights into the dynamics of exchange rates

what does purchasing power parity mean this paper examines the theoretical and empirical content of purchasing power parity ppp in efficient markets it analyzes the sources of deviations from the strictest version of ppp that exchange adjusted price levels are everywhere identical focusing on the role played by uncertainty relative price changes inappropriate price data transaction costs and government intervention in creating these deviations it then identifies and addresses the key issue involving purchasing power parity are the deviations from ppp that occur sufficiently large persistent and predictable as to enable individuals or governments to successfully exploit them an answer of no is shown to be consistent with both economic theory and the empirical evidence

exchange risk exposure and the option to trade rather than impeding trade increased exchange rate uncertainty may on average create trade as it implies a higher probability that ex post deviations from commodity price parity will exceed tariffs and transportation costs we demonstrate such an effect in a small country short term model under the alternative assumptions of perfect competition and of a monopolist trader producer the proofs rely on the fact that such firms exposures can be replicated and hedged by standard options under partial monopoly scenarios the effect of volatility is ex ante unclear though jel f31
