threshold effects in price transmission the case of brazilian wheat maize and soya prices recent studies into price transmission have recognized the important role played by transport and transaction costs threshold models are one approach to accommodate such costs we develop a generalized threshold error correction model to test for the presence and form of threshold behavior in price transmission that is symmetric around equilibrium we use monthly wheat maize and soya prices from the united states argentina and brazil to demonstrate this model classical estimation of these generalized models can present challenges but bayesian techniques avoid many of these problems evidence for thresholds is found in three of the five commodity price pairs investigated

occupational choice and the process of development this paper models economic development as a process of institutional transformation by focusing on the interplay between agents occupational decisions and the distribution of wealth because of capital market imperfections poor agents choose working for a wage over self employment and wealthy agents become entrepreneurs who monitor workers only with sufficient inequality however will there be employment contracts otherwise there is either subsistence or self employment thus in static equilibrium the occupational structure depends on distribution since the latter is itself endogenous we demonstrate the robustness of this result by extending the model dynamically and studying examples in which initial wealth distributions have long run effects in one case the economy develops either widespread cottage industry self employment or factory production employment contracts depending on the initial distribution in the other example it develops into prosperity or stagnation

integration of spatial markets studies of spatial market integration draw their implications from a theory which assumes that there are no intraregional transport costs an alternative theory is offered based on the assumptions that buyers and sellers are spatially dispersed and intraregional transport costs are significant this implies that the market is a linked oligopoly or oligopsony and that market integration tests are tests of alternative oligopoly price formation processes for example collusive basing point pricing produces results typically assumed to imply efficiently integrated markets while competitive fob pricing does not the theoretical implications are illustrated with an analysis of hog prices in canada

credit market constraints consumption smoothing and the accumulation of durable production assets in low income countries investments in bullocks in india in this paper we formulate and estimate a finite horizon structural dynamic model of agricultural investment behavior that incorporates the major features of low income agricultural environments income uncertainty constraints on borrowing and rental markets and the use of investment assets to generate income and smooth consumption the model is fit to longitudinal indian household data on farm profits bullock stocks and pump sets the estimated structural parameters are used to assess the effects on the life cycle accumulation of bullocks agricultural profits and welfare associated with complete markets and bullock liquidity and with second best policies that provide assured sources of income to farmers and weather insurance

determination of the international maize price what is the growing role of brazil and ukraine this paper examines the relationships among maize prices for four countries to determine if newly emerging exporters brazil and ukraine influence the international price of maize our work focuses on each market s participation in the price discovery process rather than trying to determine a price leader we find that the united states plays the largest role in price discovery followed by argentina brazil and ukraine we also search for export thresholds and find that ukraine s contribution to price discovery rises slightly when an export threshold of 2 3 million tons is reached no export thresholds were found for brazil export thresholds for argentina were found but only have a minor impact on price relationships we also found that price relationships vary considerably across seasons of the year

fiscal policy seasonality and intertemporal substitution of investment spending in the uk abstract the effects of three pre announced changes in fiscal policy on manufacturing investment in equipment and in industrial buildings are estimated using the enger granger two step procedure the strong seasonal variation in the expenditure series is interpreted as an economic process within the same framework

using market intelligence for the opportunistic shipping of fresh produce abstract the main goal of this paper is to develop an opportunistic shipment policy that increases a farmer s commercialization reach within a secondary market with minimal or no capital investment once a base market has been established basically the operation would consist of sending fresh produce items into a secondary market from the base whenever momentary price differentials allows two market transactions with a high probability of profit a theoretical model is developed that maximizes potential operational revenues based on arbitrage opportunities existent within two market structures ultimately the validity and applicability of this model is demonstrated through the application of a case study the results of the case study show that using the decision making strategy defined by the proposed theoretical model cannot only increase the long term profits of two market operations but can also lower the profit variability in comparison to only commercializing in a single base market

empirical implications of alternative models of firm dynamics abstract this paper considers two models of firm behavior that allow for heterogeneity among firms idiosyncratic or firm specific sources of uncertainty and discrete outcomes exit and or entry both the characteristics of firm level panel data sets and the nature of the questions we characteristically ask of them imply that models with these features are likely to underlie most detailed empirical work on microdata sets the models we consider are a bayesian learning model due to jovanovic 20 and a model of research and exploration due to ericson and pakes 11 the paper provides a simple set of empirical procedures to help determine which if either of these two models might be appropriate for alternative data sets we conclude by checking for the implications of the two models on an eight year panel of wisconsin firms the results indicate that one model is consistent with the data on manufacturing firms while the other is consistent with the data on retail trade journal of economic literature classification numbers c52 l60 l80

estimating the degree of market integration existing tests of spatial market integration are commonly based on statistical criteria without an explicit link to an economic model of price determination this article proposes new measures of market integration defined directly in terms of a well known spatial price determination model and develops an econometric methodology for estimating these measures due to the intractability of the conditional density function of prices we use indirect inference to estimate the model parameters and market integration measures the methodology is illustrated with simulated data and is applied to soybean price data for the united states brazil and the eu copyright 2008 oxford university press

on analyzing the world distribution of income consideration of world inequality should cause reexamination of the key concepts underlying the welfare approach to measuring income inequality and its relation to measuring poverty this reexamination leads to exploration of a new measure that allows poverty and inequality to be considered in the same framework incorporates different approaches to measuring inequality and allows varied expressions of the cost of inequality applied to the world distribution of income for 1820 1992 the new measure provides different perspectives on the evolution of global inequality

spatial market efficiency and policy regime change seemingly unrelated error correction model estimation we investigate the degree to which the wheat markets of france germany and the united kingdom are in spatial equilibrium and how reforms to the cap affect the speed of convergence to the longrun relationship due to the interrelationship among these markets and the nonstationarity of our data we introduce a seemingly unrelated regression augmented dickey fuller and error correction methodology we argue this methodology is more efficient than ordinary cointegration and error correction models empirically we find strong evidence of efficient spatial markets and conformity to the law of one price market liberalization reforms in the eu increased the comovement of domestic and world wheat prices our post uruguay round price transmission elasticity was 0 183

is subsidising tourism firms an effective use of public funds abstract this study assesses the impact of state aid on firms in the tourism sector by implementing an accurate micro econometric evaluation of their causal effect analyses consider subsidies allocated by the main regional policy in italy the law 488 1992 during the period 1999 2003 a matching difference in difference mdid estimator is applied considering the presence of selection on observable and non observable factors effects on the tourism sector are compared with those in the manufacturing industry the impacts with respect to different types of tourism destinations where tourism firms operate are also evaluated the results show higher output and employment growth but lower labour productivity dynamics in subsidised firms relative to non subsidised ones the impacts are diverse across types of tourism destinations

tax incentives and job creation in the tourism sector of brazil s sudene area summary in recent decades a significant number of developing countries have implemented fiscal incentives programs for the tourism industry as part of their regional development policies the main objective of these programs is to increase local investment and employment as tourism activities are labor intensive little evidence is available however to assess the effect of these policies on job creation in emerging markets in this paper we analyze a program of fiscal incentives introduced by the brazilian federal government in the sudene area in 2002 and in which tourism firms were eligible to participate through a difference in difference estimation we compare the change in the logarithm of local employment in the sudene municipalities before and after 2002 to the change in the same outcome in a group of municipalities that were not affected by the program although our empirical analysis does not measure the efficiency of a similar fiscal policy it is the first one in the literature to show its effectiveness it provides evidence that the fiscal incentives led to a substantial increase in tourism employment in the sudene area we find that over the period 2002 09 municipal tourism employment was on average 30 higher than in the absence of the intervention this result is robust and is not the consequence of either displacement effects or job destruction in neighboring municipalities that had not been targeted by the tax incentives we finally discuss some limitations of our analysis that might open avenues for future research in the field

investment crowding out firm level evidence from northern germany michalek j ciaian p and kancs d a investment crowding out firm level evidence from northern germany regional studies the main objective of this paper is to estimate the extent to which firm investment is substituted crowded out by investment support policies granted under the european union rural development programme rdp the empirical analyses employed the difference in difference propensity score matching approach which allows several important sources of bias to be addressed such as selection bias simultaneity bias and functional form misspecification from which many previous studies suffer using panel data of 1333 firms from the schleswig holstein region in germany it is found that the crowding out effect of the rdp is close to 100 implying that firms use public support to substitute for private investments furthermore no evidence was found that due to the rdp programme support firms would have brought forward their investments planned originally for a later period rejecting t

income distribution and macroeconomics this paper analyzes the role of wealth distribution in macroeconomics through investment in human capital it is shown that in the presence of credit markets imperfections and indivisibilities in investment in human capital the initial distribution of wealth affects aggregate output and investment both in the short and in the long run as there are multiple steady states this paper therefore provides an additional explanation for the persistent differences in per capita output across countries furthermore the paper shows that cross country differences in macroeconomic adjustment to aggregate shocks can be attributed among other factors to differences in wealth and income distribution across countries

cointegration and market integration an application to the indonesian rice market this article suggests improvements in the use of regression analysis to measure spatial market integration the procedure pioneered by ravallion is still widespread but is valid only under certain conditions of exogeneity the alternative offered here is an error correction mechanism which makes it possible to test for exogeneity as well as indicating the direction and strength of causality in price formation between markets the method is illustrated with data on rice prices in different parts of the indonesian market the results confirm among other things that supply sources are more important than demand sources in driving prices

the extent pattern and degree of market integration a multivariate approach for the brazilian rice market the extent pattern and degree of integration are analyzed in a multivariate system with cointegrating restrictions the extent of the market is found by identifying locations that are linked by trade and where prices share identicall ong run information permanent component the pattern of integration characterizes interdependence and is analyzed by estimating a vector error correction model the degree of integration is calculated with persistence profiles of the long run relations we demonstrate that bivariate models are inadequate for capturing the spatial dynamics of price adjustment the methodology is applied to the brazilian rice market and policy implications are

organized crime and business subsidies where does the money go abstract business support policies are widespread in advanced countries to foster employment and productivity this paper analyses the role of organized crime in the allocation of public subsidies to businesses we assemble an innovative data set on the italian mafia at municipality level and test whether mafia ridden municipalities receive a disproportionally higher amount of funds we exploit exogenous variation at municipality level to instrument mafia activity and show that the presence of organized crime positively affects the probability of obtaining funding and the amount of public funds organized crime is also found to lead to episodes of corruption in the public administration sector a series of robustness checks confirms the above findings

the effectiveness of the public support policies for the european industry financing as a contribution to sustainable development in recent years the debate about the role of the public institutions in the fields of corporate social responsibility and sustainable development has gained momentum nevertheless the ambiguity of the latter concepts makes it difficult both to measure them and to estimate the impact that the different public initiatives may have on them in this sense the present research has the aim to design a fuzzy logic based methodology applied to the evaluation of the above mentioned processes in relation to the state aid policies for the european industry regarding the study contour the european union state aids seems not to have introduced important changes leading to socially responsible results and therefore favourable for the sustainable development generated by the european manufacturing industry

how is the liberalization of food markets progressing market integration and transaction costs in subsistence economies we propose a modification of baulch s parity bounds model to measure the market integration of food markets in developing countries instead of extrapolating a single observation of transaction costs we estimate transaction costs predicted transaction costs compare well with survey data of traders probabilities of market regimes computed on the basis of predicted transaction costs fluctuate significantly and do not support fixed regime probabilities over time the probability of market integration with trade decreases consistently during food shortages increasing either the probability of no trade or loss making trade or the probability of profitable but unexploited trade opportunities the data further support a negative trend in market integration with trade

do neoliberal policies deter political corruption this article probes the relationship between neoliberal economic poli cies and political corruption focusing in particular on the impact of trade and invest ment policies regulatory policy and the overall size of the public sector on corruption using a large cross national data set from the mid to late 1990s we test the neolib eral hypotheses that market oriented economic policies are associated with lower lev els of political corruption and state intervention in the economy with higher levels consistent with the neoliberal argument we find that open trade and investment pol icies and low effective regulatory burdens do correlate with lower levels of political corruption however we find no consistent relationship between the aggregate size of the public sector and political corruption while the neoliberal hypothesis on polit ical corruption has initial empirical support its lessons cannot be applied wholesale market oriented states may be less corrupt but interventionist states as measured by public spending are not necessarily more corrupt

testing market integration new approaches with case material from the west bengal food economy given the inferential dangers of received methods a new methodology is introduced to provide a sequence of tests using weekly spot prices to examine the dynamic relationship of market commodity prices in three locations in west bengal tests suggest that the markets are integrated but a lower degree of integration of paddy and rice prices is identified the hypothesis of full market integration is rejected structural and institutional factors which affect the specifics of performance are identified physical isolation the institutional complexity of marketing systems and contractual forms the polarisation of assets assets specificity the institutional control of information and price formation the underdevelopment of linked markets and the idiosyncratic implementation of state regulatory policy and auto regulatory responses enter the explanation

the effectiveness of investment subsidies evidence from a regression discontinuity design this paper analyzes the effects of an investment subsidy program for small and medium sized enterprises in flanders from 2004 to 2009 the subsidies were awarded according to a ranking system that favored young growing and productive firms with a strong cash flow granting subsidies to the highest scoring firms until the depletion of funds the nature of this allocation system creates a sharp cutoff in granting the subsidy according to the score allowing us to estimate the causal impact of the subsidies using a regression discontinuity design we find a positive effect on firm level investment employment output and productivity for the firms that were granted the subsidy but only for the small firms however the effect is small relative to the cost of the subsidy

public subsidies tfp and efficiency a tale of complex relationships this paper evaluates the impact of subsidies on the different components of tfp for granted firms long term growth the impact of capital subsidies is captured by a quasi experimental method multiple rdd exploiting the conditions for a local random experiment created by an italian industrial policy results show that capital subsidies negatively affect tfp growth in the short term and signals of positive effects appear only after 3 4 years this positive medium long term impact comes especially through technological change and not through scale impact change as may have been expected

trade taxes and tribute market liberalizations and the new importers in west africa this paper examines dynamics of state business relations in the era of trade liberalization in senegal and cote d ivoire it challenges the orthodox view that replacing nontariff barriers such as licenses and quotas with tariffs depoliticizes trade reduces commercial rent seeking activities and creates a level playing field which will encourage underground activities to surface allowing the state to capture more revenue the paper illustrates that liberalization failed to suppress commercial rent seeking helped to encourage the ascendancy of new politically connected merchant groups the mourides in senegal and the lebanese in cote d ivoire and to some degree increased tax evasion leading to the further erosion of state revenue flows the cases show that trade centered rentierism is rooted in structural features of these west african economies

neoliberalism and the transformation of populism in latin america the peruvian case latin american populism is generally associated with the developmental stage of import substitution industrialization it is thus widely presumed to have been eclipsed by the debt crisis of the 1980s and the free market reforms of the neoliberal era however the leadership of alberto fujimori in peru suggests that new forms of populism may be emerging despite the fiscal constraints of neoliberal austerity this new variant of populism thrives in a context where economic crisis and social dislocation undermine traditional representative institutions enabling personalist leaders to establish unmediated relationships with heterogeneous atomized masses political support can be cultivated through populist attacks on entrenched political elites or institutions along with targeted but highly visible poverty alleviation programs this new form of populist autocracy complements the efforts of neoliberal technocrats to circumvent the representative institutions that are integral to democratic accountability the peruvian case thus demonstrates that populism has been transformed rather than eclipsed during the neoliberal era and that it should be decoupled theoretically from any particular phase or model of economic development

investment tax incentives prices and the supply of capital goods using data on the prices of capital goods this paper shows that much of the benefit of investment tax incentives does not go to investing firms but rather to capital suppliers through higher prices the reduction in the cost of capital from a 10 percent investment tax credit increases equipment prices 3 5 7 0 percent this lasts several years and is largest for assets with large order backlogs low import competition or with a large fraction of buyers able to use investment subsidies capital goods workers wages rise too instrumental variables estimates of the short run supply elasticity are around 1 and can explain the traditionally small estimates of investment demand elasticities in absolute value the demand elasticity implied here exceeds 1

evaluating the impact of investment incentives the case of italy s law 488 1992 abstract italy s law 488 1992 allows firms willing to invest in lagging areas to receive a public subsidy by comparing subsidized firms with firms with rejected applications this paper evaluates whether the program made investments possible that otherwise would not have been made we find evidence that financed firms brought forward investment projects originally planned for the post intervention period to take advantage of the incentives we also find some support that subsidized firms may have taken some of the investment opportunities that unsubsidized firms would have exploited in the absence of incentives

market analysis methods are our enriched toolkits well suited to enlivened markets the past fifteen years have brought historic reduction of government intervention in agricultural markets in the developing world most economists and policy makers believe these reforms enliven markets previously fettered by excessive government authority nonetheless the impact of market oriented reforms on the spatial and intertemporal extent and the competitiveness of markets remains an inherently empirical question meanwhile there also have been major innovations in methods used to analyze markets and prices due largely to the rapidly emerging time series econometric literature agricultural economists toolkits have changed nearly as rapidly and dramatically as have developing economy markets but can these enriched toolkits answer the

temporal aggregation of univariate and multivariate time series models a survey abstract we present a unified and up to date overview of temporal aggregation techniques for univariate and multivariate time series models explaining in detail although intuitively the technical machinery behind the results some empirical applications illustrate the main issues

dynamic effects of permanent and temporary tax policies in a q model of investment abstract this paper incorporates the tax policy analysis of hall and jorgenson into a dynamic optimizing model with adjustment costs to develop a q model of investment this framework is particularly useful for analyzing the dynamic effects on investment of permanent and temporary changes in tax policy it is shown that contrary to the conventional intertemporal substitution argument a temporary investment tax credit need not be nore expansionary than a permanent investment tax credit the role of depreciation allowances in determining the dynamic response of investment to temporary changes in the tax rate is also investigated

the difficult transition from clientelism to citizenship lessons from mexico author s fox jonathan a abstract electoral competition is necessary but not sufficient for the consolidation of democratic regimes not all elections are free and fair nor do they necessarily lead to actual civilian rule or respect for human rights if there is more to democracy than elections then there is more to democratization than the transition to elections but in spite of the rich literature on the emergence of electoral competition the dynamics of political transitions toward respect for other fundamental democratic rights is still not well understood political democracy is defined here in classic procedural terms free and fair electoral contestation for governing offices based on universal suffrage guaranteed freedoms of association and expression accountability through the rule of law and civilian control of the military although analyses of democratization typically acknowledge that these are all necessary criteria most examine only electoral competition this study however develops a framework for explaining progress toward another necessary condition for democratization respect for associational autonomy which allows citizens to organize in defense of their own interests and identities without fear of external intervention or punishment

too much investment a problem of asymmetric information this paper shows that under plausible assumptions the inability of lenders to discover all of the relevant characteristics of borrowers results in investment in excess of the socially efficient level raising the rate of interest above the free market level will restore optimality this conflicts with generally held views and is contrasted with the stiglitz weiss model it is shown that the assumptions which yield overinvestment support debt as the equilibrium method of finance however under the stiglitz weiss assumptions used to derive an underinvestment result equity is shown to be the equilibrium method of finance

the incidence of mandated maternity benefits i consider the labor market effects of mandates which raise the costs of employing a demographically identifiable group the efficiency of these policies will be largely dependent on the extent to which their costs are shifted to group specific wages i study several state and federal mandates which stipulated that childbirth be covered comprehensively in health insurance plans raising the relative cost of insuring women of childbearing age i find substantial shifting of the costs of these mandates to the wages of the targeted group correspondingly i find little effect on total labor input for that group jel 118 j32 h51 in an era of tight fiscal budget constraints mandating employer provision of workplace benefits to employees is an attractive means for a government to finance its policy agenda consequently in recent years there has been a growth of interest in mandated benefits as a tool of social policy for example the centerpiece of president bill clinton s health care proposal is mandated employer provision of health insurance and more than 20 states have man

a sustainable vegetable supply chain using plant factories in taiwanese markets a nash cournot model abstract sustainable plant factory systems are able to provide steady and high quality plants to markets while using less labor water nutrition and pesticides a plant factory is a controlled environment for plant production systems with artificial light temperature humidity carbon dioxide water supply and cultivation solution this paper focuses on the entry and competition of a plant factory supply chain in vegetable markets using a nash cournot model to simulate this competition the lagrangian multiplier method is used to derive kkt optimality conditions for the model combining the optimality conditions yields a linear complementarity problem lcp which is solved by gams and path a case study of the plant factory supply chain in nine taiwanese vegetable markets is presented the research simulates the impact of the location of plant factories number of firms and different market demands the results show that total production and profits of the plant factory supply chain increase as transportation costs decrease in addition the producer surplus consumer surplus and total surplus of the plant factory supply chain in taiwanese markets improve when factories are located close to the markets a sensitivity analysis is conducted which shows the impact of market share and production cost on the plant factory supply chain while the case study focuses on the taiwanese agricultural commodity production the methodology and analysis procedures have generalizability to similar plant production industry problems in other contexts

do subsidies to private capital boost firms growth a multiple regression discontinuity design approach there is still little consensus among economists on the effectiveness of business support policies the evaluation of such policies requires a reliable identification procedure that is hardly achieved in empirical studies we analyse the impact of a policy instrument law 488 92 l488 the main italian regional policy that allocates subsidies to private firms by a multiple ranking system thanks to the peculiar l488 selection process that creates the conditions for a local random experiment we are able to assess the effectiveness of these types of incentives for a relevant subgroup of firms we propose a nonparametric multiple rankings regression discontinuity design that exploits the sharp discontinuities in the l488 rankings and extends the regression discontinuity design rdd approach to a context where the treatment is assigned by multiple rankings with different cut off points we find that the impact of the subsidies on employment investment and turnover is positive and statistically significant while the effect on productivity is mostly negligible the new subsidised capital is additional but non complementary with the owner financed investment the results are robust to different specifications and not due to intertemporal substitution

do economic instruments matter wind turbine investments in the eu 15 abstract this paper analyses how governments in the eu 15 countries have succeeded in stimulating investments in wind turbines between 1985 and 2005 i use four different evaluation criteria tobin s q euler equation estimation investment accelerator model and the effective marginal tax rate to describe the observed investment patterns after a period of rapid growth in capital stock 1985 2000 a period of modest growth 2001 2005 can be observed even though the economic attractiveness of investing increases modestly this pattern cannot be explained by the evaluation criteria unless we accept economic attractiveness is a necessary condition and not a necessary and sufficient condition when analysing which policy has worked best the policies of germany denmark and spain stand out their early and consistent support has been based on feed in tariffs combined with subsidies

political manipulations and market reforms failures economists have recently underscored that the failure of market reforms in producing sustained growth in emerging markets is the result of poor advice from the international monetary fund as well as of erroneous macroeconomic policies of domestic decision makers this article proposes a complementary hypothesis if market reforms are enacted in a political system with weak accountability institutions then one should expect the executive to manipulate such reforms in pursuit of such old fashioned practices as collusion between government and business political patronage and corruption this in turn ends up depriving a given economy of potential advantages that could have accrued had the reforms promoted true competition rather than reallocating monopolistic rents and squandering a large amount of resources

the labor market impact of immigration in western germany in the 1990 s in this article we estimate the wage and employment effects of recent immigration in western germany using administrative data for the period 1987 2001 and a labor market equilibrium model we find that the substantial immigration of the 1990s had very little adverse effects on native wages and on their employment levels instead it had a sizeable adverse employment effect on previous immigrants as well as a small adverse effect on their wages these asymmetric results are partly driven by a higher degree of substitution between old and new immigrants in the labor market and in part by the rigidity of wages in less than flexible labor markets in a simple counter factual experiment we show that in a world of perfect wage flexibility and no unemployment insurance the wage bill loss of old immigrants would be much smaller

political capital mexican financial policy under salinas market reform is advocated in developing countries to improve economic efficiency and prevent privileged groups from obtaining rents from the policy making process yet this prescription fails to address the complex political process that governments are likely to confront when moving toward the market this study shows how political considerations during president salinas s administration distorted economic reform in mexico during the 1990s mexican finance policy contradicted the government s declared neoliberal principles while the banks were reprivatized and deregulated they were also given a high degree of protection from competition enabling the new owners to charge excessive interest rates in addition the government artificially inflated the value of the currency through exchange rate intervention these contradictory policies are best understood as a coherent political response to the electoral vulnerability of the ruling party pri at the end of the 1980s when viable political opposition threatened the pri s ability to maintain power it responded by using financial policies to distribute economic benefits to social groups particularly business the middle class and the poor whose support was critical for electoral victory

the craft of labormetrics using a wide array of examples from the literature and from original estimates the author examines the pitfalls that make good empirical research in labor economics at least as much craft as statistical technique among the subjects discussed are the appropriateness and cleanliness of data problems of extreme observations the validity of attempts to produce exogeneity using instrumental variables natural experiments and structural models and the treatment of selectivity and unobservable individual effects the author stresses the importance of testing empirical results to ensure that they make sense and of presenting them clearly and economically

modelling trends in food market integration method and an application to tanzanian maize markets abstract pushed by increasing availability of price data and extensive market liberalisation efforts in many developing countries research on food market integration has evolved rapidly over the last two decades empirical methods to measure market integration diverged in two directions on the one hand there is the parity bounds model pbm using a switching regressions technique while on the other hand the use of threshold autoregressive tar models has been proposed this article provides a discussion on the two methods and argues that tar models are better able to capture the dynamics of the arbitrage process underlying interconnected markets furthermore we extend the standard tar model to include a time trend in both the threshold and the adjustment parameter using weekly maize price data on seven selected markets in tanzania we illustrate how both transaction cost and the speed of adjustment have changed during the nineties

a transaction level analysis of spatial arbitrage the role of habit attention and electronic trading despite the central role of arbitrage in finance and economic theory there is limited evidence of the factors that create and eliminate arbitrage opportunities how often arbitrage occurs and how profitable it is we address these gaps via a transaction level analysis of spatial arbitrage in the wholesale automotive market we investigate why arbitrage opportunities are created by analyzing how sellers choose where to sell vehicles we find that the attention sellers pay to the distribution of a vehicle is negatively related to the probability that it is arbitraged arbitrage occurs in approximately 1 of transactions although electronic trading is making arbitrage less prevalent by improving buyer seller matching across locations arbitrage yields a 5 6 return on average although arbitrageurs take a loss 14 of the time our results contribute to the literature on arbitrage the effect of attention allocation on market outcomes and the effect of information technology on market efficiency this paper was accepted by brad barber teck ho and terrance odean special issue editors

fighting inflation in a transitional regime russia s anomalous stabilization russia s recent experience fighting inflation dramatic success in 1995 96 after repeated failures in 1992 94 poses a challenge for existing theories of the politics of macroeconomic stabilization monthly inflation rates fell to close to zero despite a deeply unpopular president distracted by heart disease a government penetrated by economic lobbies a far from independent central bank a parliament dominated by opposition factions a lively election season and the fiscal pressures of fighting a regional war the article reviews this experience shows its incompatibility with existing political economy theories and proposes an explanation with implications for other reforming regimes success was achieved by offering previous beneficiaries from inflation major commercial banks and subsidized sectors other sources of government protected rents that did not increase the money supply even when expropriating powerful rent seekers is politically infeasible it is sometimes possible to trade them less inflationary rents for ones that are more inflationary

market reform as a stimulus to particularistic politics we know little about how market reform affects political development especially citizens behavior market reform advocates prescribe that citizens should reduce their reliance on the state turn to nonstate actors for assistance and obtain limited state goods and services through their membership in certain social categories not their particular traits an analysis of three mass surveys and 232 interviews the author conducted in central asia along with additional data from 24 postcommunist countries reveals that market reform can have effects opposite from those prescribed individuals may make particularistic demands of government officials instead of relying on nonstate actors this occurs in countries where state economic intervention was substantial and where reforms reduced the state s economic role but failed to develop market enhancing institutions under these conditions individuals informally seek resources from state officials because nonstate actors do not offer substitute resources and

assessing the incidence and efficiency of a prominent place based policy abstract this paper empirically assesses the incidence and efficiency of round i of the federal urban empowerment zone ez program using confidential microdata from the decennial census and the longitudinal business database using rejected and future applicants to the ez program as controls we find that ez designation substantially increased employment in zone neighborhoods and generated wage increases for local workers without corresponding increases in population or the local cost of living the results suggest the efficiency costs of first round ezs were relatively modest jel h26 h77 j31 r23 r58

balladurette and juppette a discrete analysis of scrapping subsidies this paper studies the effects of subsidies on durable goods markets in particular we focus on a recent policy in france in which the governments of balladur and juppe subsidized the replacement of old cars with new ones to study this policy we construct a dynamic stochastic discrete choice model of car ownership at the household level the resulting decision rules and equilibrium conditions are used to estimate the underlying parameters of the model using aggregate data these policy functions are used to evaluate the short and long run effects of the french policies we find that these policies do stimulate the automobile sector in the short run but through the induced changes in the cross sectional distribution of car ages create the basis for subsequent low activity further while these policies increase government revenues in the short run revenues in the long run are lower relative to a baseline without intervention

a model of spatial arbitrage with transport capacity constraints and endogenous transport prices this article solves a high frequency model of price arbitrage incorporating storage and trade when the amount of trade is limited by transport capacity constraints in equilibrium there is considerable variation in transport costs because transport costs rise when the demand to ship goods exceeds the capacity limit this variation is necessary to attract shipping capacity into the industry in turn prices in different locations differ by a time varying amount thus while the law of one price holds it holds because of endogenous variation in transport costs

investment tax incentives and frequent tax reforms despite the frequency of tax changes and their potential importance to investors almost all of the analysis of tax based investment incentives assumes investors never anticipate any tax changes we depart from this approach by analyzing the historical pattern of u s corporate investment incentives over the period 1953 86 incorporating the feature of investor awareness that the tax code may change our analysis incorporates a predictive equation for future tax variables into a model of optimal investment subject to adjustment costs and uncertainty we find that expectations of future tax changes significantly affect the incentive to invest only if adjustment costs are low in this case the incentive to invest in 1986 was strong as investors are estimated to have anticipated the coming reduction in investment incentives this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item

rent capture analysis of ontario s stumpage system using an enhanced parity bounds model we develop and use an enhanced parity bounds model epbm to examine the discrepancy between the stumpage price administratively determined under ontario s current stumpage pricing system and the market value of stumpage covering from june 1995 to january 2007 the results show that in the short run the stumpage prices were below or above the market values however in the long run the underpayment and overpayment will even out each other the results imply that ontario s stumpage pricing system has the ability to capture the full economic rents in the long run and the results also have other policy implications

transfer costs spatial arbitrage and testing for food market integration conventional tests for food market integration ask often misleadingly whether prices in different locations move together in this paper an alternative methodology the parity bounds model pbm is developed which uses information on transfer costs in addition to food prices to assess the efficiency of spatial arbitrage monte carlo experiments using data generated by a point space spatial price equilibrium model show the pbm to be statistically reliable an application to philippine rice markets demonstrates that the pbm detects efficient arbitrage when other tests do not

market integration efficiency of arbitrage and imperfect competition methodology and application to u s celery this paper develops and applies a methodology to test for efficiency of interregional commodity arbitrage application of the methodology requires only time series data on prices for alternative cities regions countries or product forms yet the approach is capable of generating evidence on a number of market parameters including market integration arbitrage efficiency the magnitude of marketing margins product substitutability and competitiveness of markets estimation is based on a switching regression model with three regimes efficient arbitrage relative shortage and relative glut results from application of the model to u s celery marketing indicated significant departures from efficient arbitrage for both california and florida celery

evaluating the employment impact of a mandatory job search program this paper exploits area based piloting and age related eligibility rules to identify treatment effects of a labor market program the new deal for young people in the u k a central focus is on substitution displacement effects and on equilibrium wage effects the program includes extensive job assistance and wage subsidies to employers we find that the impact of the program significantly raised transitions to employment by about 5 percentage points the impact is robust to a wide variety of nonexperimental estimators however we present some evidence that this effect may not be as large in the longer run jel j18 j23 j38

optimal monetary policy under low trend inflation abstract in the monetary policy literature it is common to assume that trend inflation is zero despite overwhelming evidence that zero inflation is neither empirically relevant nor a practical objective for central bank policy we therefore extend the standard new keynesian model to allow for positive trend inflation showing that even low trend inflation has strong effects on optimal monetary policy and the dynamics of inflation output and interest rates under discretion the efficient policy deteriorates and there is no guarantee of determinacy even with commitment targeting non zero trend inflation leads to substantial welfare losses our results serve as a warning against indiscriminate use of models assuming zero trend inflation

competing for global capital or local voters the politics of business location incentives the competition for global capital has led to interjurisdictional competition between countries states and cities as to who can offer the most attractive incentives to firms in this study we examine the domestic politics of this competition by focusing on incentive use in the united states from 1999 to 2012 we define incentives as the targeted tax deductions or exemptions that are used to lure businesses into a locality drawing on data from municipal incentive programs we examine how electoral competition shapes the use and oversight of targeted incentives we find evidence that cities with elected mayors provide larger incentives than non elected city managers by taking advantage of exogeneity in the assignment of city government institutions and a database of over 2000 investment incentives from 2010 to 2012 we also find that elected mayors enjoy more lax oversight of incentive projects than their appointed counterparts our results have important implications for the study of interjurisdictional competition and the role of electoral institutions in shaping economic policy

determinants of the internationalization of regions the role and effectiveness of public policy measures banno m piscitello l and varum c determinants of the internationalization of regions the role and effectiveness of public policy measures regional studies this paper assesses the role of public policy measures on outward internationalization of regions by including financial and non financial incentives among the determinants of the international competitiveness of regions it is found that the former are important to enhance their active internationalization but that variables related to the knowledge and competence base of regions are even more so financial incentives related to equity participation as well as non financial incentives related to the provision of information come out highly significant in stimulating outward internationalization the empirical analysis is conducted for the twenty italian nuts 2 regions over the period 2003 2008

evaluation of spatial effects of capital subsidies in the south of italy de castris m and pellegrini g evaluation of spatial effects of capital subsidies in the south of italy regional studies the spatial effects of capital subsidies are neglected in the literature even if several industrial policies have a strong spatial dimension this study disentangles the spillovers generated by subsidized firms from the spatial attraction across neighbour s areas that cannot be attributed to incentive the presence of specific spatial effects is tested on the reduced form of a spatial autoregressive model evaluating the implicit common factor restriction the empirical analysis considers the main regional policies in the period 1996 2001 in the south of italy the results suggest the presence of a modest spatial crowding out where subsidized regions attract employment from neighbouring areas de castris m et pellegrini g une evaluation des effets geographiques des subventions d equipement dans le sud de l italie regional studies la documentation ne fait aucune attention aux effe

testing market integration a model of spatial price differentials for a tradable good is proposed which avoids the inferential dangers of received methods using static price correlations the proposed method also extracts more information on the causes of price differentials from the same data the method is illustrated using monthly rice price data for postindependence bangladesh including the very substantial regional price shocks during the 1974 famine impediments to market integration are indicated

spatial market integration in the presence of threshold effects a large body of research has evaluated price linkages in spatially separate markets much recent research has applied models appropriate for nonstationary data such analyses have been criticized for their ignorance of transactions costs which may inhibit price adjustments and thus affect tests of integration this analysis utilizes threshold autoregression and cointegration models to account for a neutral band representing transactions costs we evaluate daily price linkages among four corn and four soybean markets in north carolina nonlinear impulse response functions are used to investigate dynamic patterns of adjustments to shocks our results confirm the presence of thresholds and indicate strong support for market integration though adjustments following shocks may take many days to be complete in every case the threshold models suggest much faster adjustments in response to deviations from equilibrium than is the case when threshold behavior is ignored a large amount of empirical research has evaluated the extent to which spatially separate markets are integrated though the term is used loosely in the literature tests of market integration usually consider the extent to which shocks are transmitted among spatially separate markets the integration of markets can have important implications for price discovery and the operation of the market since persistent deviations from integration may imply riskless profit opportunities for spatial traders

causal effect of credit guarantees for small and medium sized enterprises evidence from italy we evaluate the effectiveness of a partial credit guarantee program implemented in a large italian region that aimed to improve the access to credit of small and medium enterprises using unique microdata from a broad set of firms we show that the policy increased the long term loans for beneficiary firms while the total volume of bank loans was unaffected furthermore targeted firms benefited from a substantial decrease in interest rates however there is some evidence that firms are more likely to default as a consequence of the treatment conversely the results do not point to any significant effect on investments

the populist road to market reform policy and electoral coalitions in mexico and argentina governing parties face two fundamental tasks they must pursue policies effectively and they must win elections their national coalitions therefore generally include two types of constituencies those that are important for policy making and those that make it possible to win elections in effect governing parties must bring together a policy coalition and an electoral coalition this distinction sheds light on how the transitional costs of major economic policy shifts can be made sustainable in electoral terms it also provides a starting point for analysis of how two of latin america s most important labor based parties the peronist party in argentina and the partido revolucionario institucional pri in mexico maintained electoral dominance while pursuing free market reforms that adversely affected key social constituencies peronism and the pri are conceived of as having encompassed historically two distinctive and regionally based subcoalitions a metropolitan coalition that gave support to the parties development strategies and a peripheral coalition that carried the burden of generating electoral majorities this framework permits a reconceptualization of the historic coalitional dynamics of peronism and the pri and sheds light on the current process of coalitional change and economic reform

on market integration and liberalisation method and application to ethiopia the article suggests further improvements in the methodology to analyse market integration it provides corrections to and methodological extensions of recent work in this journal it also presents a way of applying market integration techniques to the analysis of shocks such as market liberalisation and war the method is applied to the effects of liberalisation and the end of the civil war on food markets in ethiopia the conclusion is that liberalisation had important effects on the long run and short run integration of food markets
