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

food versus fuel an updated and expanded evidence abstract this paper replicates the study of zhang et al 2010 food versus fuel what do prices tell us energy policy 38 pp 445 451 we confirm the findings of the original paper that there was only a weak relationship between ethanol and food commodities in the period between march 1989 and july 2008 in addition we extend that study and examine the cointegration relationship between biofuels and related commodities for a considerably enlarged dataset 3 vs 1 market 26 vs 8 commodities analysis up till 2017 vs 2008 weekly vs monthly data frequency focusing on the biofuel markets of brazil the eu and the usa in the three separate periods before during and after the food crisis of 2007 and 2008 we show that studying the time variation of the relationships plays an essential role in their proper understanding our results help to clarify the wide extensive discussion about the role of biofuels prices in food shortages manifested particularly during the food crises in agreement with the original study we confirm that price series data do not support strong statements about biofuels uniformly serving as main leading source of high food prices and consequently the food shortages

group lending repayment incentives and social collateral abstract in this paper we investigate the impact on repayment rates of lending to groups which are made jointly liable for repayment this type of scheme especially in the guise of the grameen bank in bangladesh has received increasing attention we set up and analyze the repayment game which group lending gives rise to our analysis suggests that such schemes have both positive and negative effects on repayment rates the positive effect is that successful group members may have an incentive to repay the loans of group members whose projects have yielded insufficient return to make repayment worthwhile the negative effect arises when the whole group defaults even when some members would have repaid under individual lending we also show how group lending may harness social collateral which serves to mitigate its negative effect

correlations between biofuels and related commodities before and during the food crisis a taxonomy perspective abstract in this paper we analyze the relationships between the prices of biodiesel ethanol and related fuels and agricultural commodities with a use of minimal spanning trees and hierarchical trees to distinguish between short term and medium term effects we construct these trees for different frequencies weekly and monthly we find that in short term both ethanol and biodiesel are very weakly connected with the other commodities in medium term the biofuels network becomes more structured the system splits into two well separated branches a fuels part and a food part biodiesel tends to the fuels branch and ethanol to the food branch when the periods before and after the food crisis of 2007 2008 are compared the connections are much stronger for the post crisis period this is the first application of this methodology on the biofuel systems

reassessment of the tiebout model abstract the tiebout model has been the reference point for the classical approach to fiscal federalism its emphasis on mobility benefit taxation and the advantages of fiscal competition have informed fiscal federalism since the seminal contributions of musgrave and oates this paper reviews the influence that the tiebout model has had on fiscal federalism and argues that while its insights remain relevant for local government it is far from compelling as a positive description of or a normative prescription for fiscal federalism at the state level some aspects of alternative approaches are presented which lead to different perspectives than tiebout inspired ones

interprovincial migration and local public goods the objective of this paper is to test whether fiscally induced migration occurs in canada that is whether interprovincial migration flows are influenced by government tax and expenditure policies in order to do so a multinominal logit model of migration is developed in which individuals choose to live in the province where their utility would be highest the model is estimated using aggregate data for the period 1962 81 the results indicate that migration is influenced by provincial government spending trough the magnitude and direction of the effect differs with the type of government spending the implication of these results is that intergovernmental transfer payments and provincial natural resource revenues also have the potential to influence migration flows in canada summary in fre excerpt

intergovernmental transfers and fiscal behavior insurance versus aggregate discipline abstract this paper evaluates the trade off between the advantages of risk sharing and the perils of common pool problems in federal fiscal arrangements under the assumption of asymmetric information we evaluate two alternative regimes of intergovernmental transfers in one regime the central government pre commits to a certain level of transfers that compensate vertical fiscal imbalances and provide some limited ex ante insurance in the other regime it accommodates ex post the fiscal needs of the different provinces in this second case full insurance results but the economy is subject to a tragedy of the fiscal commons with excessive subnational spending insufficient local taxation and reduced production of federal public goods we find the range of parameters for which one or the other institutional regime will be preferable the result is a fiscal federalism version of the usual trade off between rules and discretion

the economics of poverty traps and persistent poverty an asset based approach abstract longitudinal data on household living standards open the way to a deeper analysis of the nature and extent of poverty while a number of studies have exploited this type of data to distinguish transitory from more chronic forms of income or expenditure poverty this paper develops an asset based approach to poverty analysis that makes it possible to distinguish deep rooted persistent structural poverty from poverty that passes naturally with time due to systemic growth processes drawing on the economic theory of poverty traps and bifurcated accumulation strategies this paper briefly discusses some feasible estimation strategies for empirically identifying poverty traps and long term persistent structural poverty as well as relevant extensions of the popular foster greer thorbecke class of poverty measures the paper closes with reflections on how asset based poverty can be used to underwrite the design of persistent poverty reduction strategies

on the economic dividend of devolution rodriguez pose a and gill n 2005 on the economic dividend of devolution regional studies 39 405 420 recent political and academic discourse about devolution has tended to stress the economic advantages of the transfer of power from national to subnational institutions this economic dividend arises through devolved administrations ability to tailor policies to local needs generate innovation in service provision through inter territorial competition and stimulate participation and accountability by reducing the distance between those in power and their electorates this paper however outlines two related caveats first there are many forces that accompany devolution and work in an opposite direction devolved governmental systems may carry negative implications in terms of national economic efficiency and equity as well as through the imposition of significant institutional burdens second the economic gains as well as the downsides that devolution may engender are contingent to some

china s uneven progress against poverty while the incidence of extreme poverty in china fell dramatically over 1980 2001 progress was uneven over time and across provinces rural areas accounted for the bulk of the gains to the poor though migration to urban areas helped the pattern of growth mattered rural economic growth was far more important to national poverty reduction than urban economic growth agriculture played a far more important role than the secondary or tertiary sources of gross domestic product gdp rising inequality within the rural sector greatly slowed poverty reduction provinces starting with relatively high inequality saw slower progress against poverty due both to lower growth and a lower growth elasticity of poverty reduction taxation of farmers and inflation hurt the poor external trade had little short term impact

credit as insurance in agrarian economies abstract this paper examines consumption credit as an insurance mechanism in agrarian economies it explains the more rapid adoption of new technology in the green revolution by large farmers who had greater access to consumption credit the paper also demonstrates how the emergence and expansion of consumption credit markets by mitigating the need for hoarding in order to meet consumption contingencies enhances growth by encouraging investment

are there dynamic gains from a poor area development program poor area development programs in which the government transfers extra resources to unusually poor areas have been widely used to fight poverty there has been some research on such programs but little is known about their impact on household living standards over time the authors address the issue for a sizable poor area development program in rural china china s program had a significant impact on rural living standards in the targeted areas of the sample the consumption growth model suggests that households living in the targeted areas had a higher rate of consumption growth than one would have otherwise expected nonetheless the authors found that while the gains in growth were enough to prevent an absolute decline in average living standards they were not enough to reverse the strong underlying divergent tendencies in the rural economy

taxation and the international mobility of inventors we study the eect of top tax rates on superstar inventors international mobility since 1977 using panel data on inventors from the u s and european patent oces we exploit the dierential impact of changes in top tax rates on inventors of dierent qualities superstar inventors location choices are signicantly aected by top tax rates in our preferred specication the elasticity to the net of tax rate of the number of domestic superstar inventors is around 0 03 while that of foreign superstar inventors is around 1 these elasticities are larger for inventors in multinational companies an inventor is less sensitive to taxes in a country if his company performs a higher share of its research there

credit constraints credit unions and small scale producers in guatemala abstract efficient and equitable development outcomes may depend in part on whether formal financial institutions leave low wealth producers tightly constrained in their access to credit if so can cooperative institutions efficiently relax these constraints these issues are explored using survey data gathered from 950 small scale producer households in areas of guatemala with market oriented credit unions that mobilize savings and make unsubsidized loans nonprice rationing by banks is found to be common among lower wealth households while credit unions relax credit constraints for a significant portion of those rationed by banks but not the poorest of the study households

ethanol and field crops is there a price connection abstract we analyze the relationship between the prices of ethanol corn soybeans wheat and cattle in nebraska u s we focus on long run price relations short run granger causality in sample and out of sample predictability linkages between returns on ethanol field crops and cattle since the ethanol market has been subject to many policy interventions our analysis takes structural breaks and parameter instabilities into account using modern statistical techniques we find no evidence that ethanol returns granger cause food price variations conversely both in sample and out of sample results suggest that ethanol is granger caused and can be predicted by returns on corn no linkages between ethanol and cattle are found

fiscal decentralization rural industrialization and undocumented labour mobility in rural china 1982 87 chen y p fiscal decentralization rural industrialization and undocumented labour mobility in rural china 1982 87 regional studies this paper explores the relationship between fiscal decentralization which gave greater rural industrialization and fiscal authority to local governments and the emergence of rural rural undocumented inter provincial labour migration during china s initial reform period a heckman model is employed to correct for the zero observation problems and to estimate consistently the labour mobility with a modified gravity equation given the institutional barriers the fiscal decentralization has two contending effects on labour market integration local economic development promotes labour mobility but local public goods crowding restrains the inflow of labour at the destination the crowding effect is stronger at lower levels of government

credit market access and profitability in tunisian agriculture this work develops an econometric model that links credit access with agricultural profitability and investment using data collected from rural tunisia this work provides direct estimates of credit access and its effects econometric estimates are run for agricultural investment and profitability as a function of credit access the investigation of credit access and its effect suggests that the presence of credit market constraints does impinge significantly on farm profitability but not on investments

biofuel related price transmission literature a review abstract in this article an extensive review of the rapidly growing biofuel related time series literature is carried out the data used the modeling techniques and the main findings of this literature are discussed providing a review of this flourishing research area is relevant as a guidepost for future research this literature concludes that energy prices drive long run agricultural price levels and that instability in energy markets is transferred to food markets

the rural non farm economy prospects for growth and poverty reduction summary policy makers have high expectations for the rural non farm economy rnfe given high income shares growing employment and frequently low capital requirements they see the rnfe as a potential pathway out of poverty for their rural poor yet available evidence suggests that pro poor rural non farm growth does not occur automatically for the poor to benefit from rural non farm growth policy makers must stimulate buoyant rural economies with robust non farm income growth not simply low productivity employment moreover the poor must gain access to growing market niches fluid labor markets provide one important bridge linking the rural poor to growing non farm opportunities

who is credit constrained in the u s economy an important assumption of the life cycle model of consumption is the postulate of perfect capital markets this hypothesis has recently been challenged by substantial empirical evidence hall and mishkin 1982 using the panel study of income dynamics estimate that 20 percent of united states families are liquidity constrained mariger 1986 derives a life cycle model with endogenous liquidity constraints and using a cross section estimates this fraction to be 19 4 percent hubbard and judd 1986 simulate a model with a constraint on net worth which shows that with reasonable assumptions about preferences 19 0 percent of united states consumers are liquidity constrained the emerging consensus points therefore to a fraction of approximately 20 percent of the population behaving in a manner that is inconsistent with the pure life cycle model in addition hayashi 1985 and zeldes 1989 investigate the correlation among consumption wealth and income for various population groups and infer that liquidity constraints are more important for younger families with low levels of wealth and saving the main limitation of these studies is that in their data sets constrained consumers are not observable and have to be identified via indirect evidence thus there is as yet little firm evidence about the characteristics of the consumers who are likely to be credit constrained this paper adopts an approach that differs from previous tests for liquidity constraints because it makes use of data where constrained consumers are observable and explicitly links their existence to credit market imperfections and personal characteristics the data drawn from the 1983 survey of consumer finances scf and described in section ii provide information on individuals whose request for credit has been rejected by financial intermediaries in section iii a model is developed in which consumers and lenders behavior jointly determines the probability that a consumer is rationed in the credit market this probability is then

asset smoothing consumption smoothing and the reproduction of inequality under risk and subsistence constraints abstract a growing literature asks whether low wealth agents can accumulate assets over time or whether they are trapped in poverty this paper develops a stochastic dynamic programming model with endogenous asset price risk to explore savings and portfolio decisions in a resource poor environment characterized by risk and subsistence constraints optimal portfolio strategies are found to bifurcate despite divisible assets and fully rational agents wealthier agents acquire a higher yielding portfolio and pursue conventional consumption smoothing poorer agents acquire a less remunerative portfolio and pursue asset smoothing rather than consumption smoothing asset based risk coping thus results in positive correlation between initial wealth and portfolio rate of return

empirical measurement of credit rationing in agriculture a methodological survey empirical analysis of rural credit market failure has been of key scientific and political interest in recent years the aim of this article is to give an overview of the various methods for measuring credit rationing that are employed in the literature furthermore the methods are subjected to a comparative evaluation of their specific strengths or shortcomings six approaches are distinguished measurement of loan transaction costs analysis of qualitative information collected in interviews analysis of quantitative information collected in interviews using the credit limit concept analysis of spill over effects with regard to secondary credit sources econometric household modeling and the econometric analysis of dynamic investment decisions an explicit comparison with a first best solution is impossible in the first three approaches since they essentially rely on a subjective assessment of borrowers access to credit based on qualitative or quantitative indicators the fifth and sixth approaches allow a rigorous interpretation in the framework of neoclassical equilibrium theory the fourth approach takes an intermediate position since spill over on segmented loan markets reveals a willingness to pay with regard to the supposedly less expensive but rationed primary source the approaches are fairly data demanding in general usually requiring specific data on loan transactions even so most approaches are applicable to cross sectional household data with the exception of the first all methods surveyed might plausibly be used to empirically detect credit rationing

causality and predictability in distribution the ethanol food price relation revisited abstract this paper examines the relationship between biofuels field crops and cattle prices in the u s from a new perspective we focus on predictability in distribution by asking whether ethanol returns can be used to forecast different parts of field crops and cattle returns distribution or vice versa density forecasts are constructed using conditional autoregressive expectile models estimated with asymmetric least squares forecast evaluation relies on quantile weighed scoring rules which identify regions of the distribution of interest to the analyst results show that both the centre and the left tail of the ethanol returns distribution can be predicted by using field crops returns on the contrary there is no evidence that ethanol can be used to forecast any region of the field crops or cattle returns distributions

how has microcredit supported agriculture evidence using panel data from bangladesh improving agricultural productivity has received a greater attention in recent years amid concerns about rising food insecurity population pressures and climate change many believe that better access to institutional credit spanning microcredit as well as commercial and agricultural banks can help rural households smooth risks and access inputs and other technology to modernize agriculture and improve farm nonfarm linkages we use recently augmented household panel data spanning over 20 years in bangladesh to examine the effects of rural credit expansion both microcredit and formal bank channels on outcomes for agricultural households we find that microcredit has benefited households with lower landownings raising agricultural income from activities such as livestock rearing that require less land as well as nonfarm income diversification for all households but with the strongest effect for landless or near landless households we do not find effects of microcredit on crop income but do however find that reported supply side credit constraints significantly lower crop income borrowing by both men and women has contributed to nonfarm income growth for marginal farmers but only men s borrowing has contributed to nonfarm income growth among higher landowning groups

property tax and inter municipal migration in canada a multivariate test of the tiebout hypothesis this paper tests the causal ordering between property taxes and inter municipal migration using both bivariate and multivariate methods empirical results based on annual data for post war canada 1940 84 support the tiebout tullock hypothesis which implies that differential local tax system and public services induce inter comunity migration inter alia local spending and taxation are not therefore fully capitalized in property values the bivariate tests based on the granger sims test and hsiao s procedure indicate an instantaneous bidirectional causality between property taxes and migration but the multivariate granger test supports only a unidirectional causality from property taxes to migration

credit programmes for the poor and seasonality in rural bangladesh this article examines the effect of group based credit used to finance self employment by landless households in bangladesh on the seasonal pattern of household consumption and male and female labour supply this credit can help smooth seasonal consumption by financing new productive activities whose income flows and time demands do not seasonally covary with the income generated by existing agricultural activities the results based upon 1991 92 survey data strongly suggest that an important motivation for credit programme participation is the need to smooth the seasonal pattern of consumption and male labour supply it is only the extent of lean season consumption poverty that selects household into these programmes in addition the largest female and male effects of credit on household consumption are during the lean season

collateral free lending with risk contingent credit for agricultural development indemnifying loans against pulse crop price risk in india this article addresses the problem of collateral free lending in the context of agricultural development we investigate a viable alternative to traditional credit products through the development of risk contingent credit for operating loans and farm mortgages and apply the concept to agricultural loans for pulse crops in india risk contingent credit mitigates business and financial risk by reducing debt obligations depending on the embedded commodity options whose payoffs are linked with commodity price fluctuations we analyze daily commodity spot prices for pulse crops in india and show how risk contingent structured financial instruments can be priced in practice

the elasticity of taxable income with respect to marginal tax rates a critical review this paper critically surveys the large and growing literature estimating the elasticity of taxable income with respect to marginal tax rates using tax return data first we provide a theoretical framework showing under what assumptions this elasticity can be used as a sufficient statistic for efficiency and optimal tax analysis we discuss what other parameters should be estimated when the elasticity is not a sufficient statistic second we discuss conceptually the key issues that arise in the empirical estimation of the elasticity of taxable income using the example of the 1993 top individual income tax rate increase in the united states to illustrate those issues third we provide a critical discussion of selected empirical analyses of the elasticity of taxable income in light of the theoretical and empirical framework we laid out finally we discuss avenues for future research jel h24 h31 j22

the influence of taxes on migration evidence from switzerland empirical studies on the impact of taxation on migration have been limited by a lack of comparable data in an international context and a lack of variation in tax burdens within countries a notable exception to the latter is switzerland prior empirical studies on tax competition in switzerland have had to rely on aggregated data in general these studies have been supportive of the notion of tax competition i e high earners tend to relocate to low tax regions the authors use an alternative panel approach based on micro data from the first three waves of the newly established swiss household panel despite active community tax policies aimed at attracting new residents and a significant increase in tax burden dispersion among communities in the past decade no tax induced migration is observed migration decisions are found to be strongly influenced by accommodation related factors that point to important housing market effects

food versus fuel what do prices tell us abstract sorting out the impacts of biofuels on global agricultural commodity prices is impossible without turning to data and distinguishing between the short run versus the long run impacts using time series prices on fuels and agricultural commodities the aim is to investigate the long run cointegration of these prices simultaneously with their multivariate short run interactions results indicate no direct long run price relations between fuel and agricultural commodity prices and limited if any direct short run relationships in terms of short run price movements sugar prices are influencing all the other agricultural commodity prices except rice with sugar the number one world input for ethanol results indicate increased ethanol production is potentially influencing short run agricultural commodity prices overall results support the effect of agricultural commodity prices as market signals which restore commodity markets to their equilibria after a demand or supply event shock

individual tax rates and regional tax revenues a cross state analysis abstractindividual tax rates and regional tax revenues a cross state analysis regional studies this paper analyzes the effects of state level personal tax rates on state tax revenue and individual welfare the policy analysis based on a general equilibrium model suggests that tax revenues would benefit from higher wage income sales or property taxes while any increase in dividend income tax would result in a reduction of revenues it is also shown that individuals would suffer from an increase in state level wage income tax dividend tax or sales tax while they would benefit from an increase in property taxes the heterogeneity across states is determined by a taxindex a weighted average of initial taxes at the state level

nonlinearities in the u s corn ethanol oil gasoline price system we use a smooth transition vector error correction model to assess price relationships within the u s ethanol industry monthly ethanol corn oil and gasoline prices from 1990 to 2008 are used in the analysis results indicate the existence of long run relationships among the prices analyzed strong links between energy and food prices are identified

the relationship between credit and productivity in chinese agriculture a microeconomic model of disequilibrium credit is an important element in agricultural production systems it allows producers to satisfy the cash needs induced by the production cycle which characterizes agriculture preparation planting cultivation and harvesting of the crops are typically done over a period of several months in which very little cash revenue is earned while expenditures on materials purchased inputs and consumption must be made in cash cash income is received a short time after the harvest in the absence of credit markets farmers would have to maintain cash reserves so as to facilitate production and consumption in the next cycle the availability of credit allows both greater consumption and greater purchased input use and thus increases welfare of the farmers

risk credit constraints and financial efficiency in peruvian agriculture abstract based on a panel data set we use a two stage analysis to evaluate the effects of access to formal credit on financial efficiency of farms in northern peru the first stage uses non parametric data envelope analysis to estimate farm specific measures of financial efficiency 28 per cent of farmers are financially inefficient and credit constraints reduce profits of these farmers by an average of between 17 and 27 per cent the second stage uses tobit regression to evaluate the determinants of financial inefficiency the results point to uninsured risk as a key determinant of financial inefficiency and suggest that policies to strengthen agricultural insurance markets would likely pay large dividends in rural peru

direct elicitation of credit constraints conceptual and practical issues with an application to peruvian agriculture abstract this article provides a methodological bridge leading from the well developed theory of credit rationing to the less developed territory of empirically identifying credit constraints we begin by developing a simple model showing that credit constraints may take three forms quantity rationing transaction cost rationing and risk rationing each form adversely affects household resource allocation and thus should be accounted for in empirical analyses of credit market performance we outline a survey strategy to directly elicit households status as unconstrained or constrained in the credit market and if constrained to further identify which of the three nonprice rationing mechanisms is at play we discuss several practical issues that arise due to the use of a combination of factual and interpretative survey questions finally using a farm level data set from peru we illustrate how the methodology can be used to estimate the impacts of credit constraints

how infrastructure and financial institutions affect rural income and poverty evidence from bangladesh the mechanisms by which the poor benefit from economic growth remain a topic of debate in development literature we address this issue in the context of rural bangladesh using a pooled dataset of three household panels between 1991 2001 expansion of irrigation paved roads electricity and access to formal and informal credit have through different veins led to higher rural farm and non farm incomes accounting for exogenous local agroclimatic endowments that explain a large part of the variation in the growth of infrastructure and credit programmes however this has not translated into substantial reductions in poverty for the poorest households

the impact of biofuels on commodity food prices assessment of findings for years agriculture has provided most of the fuel for vehicular transportation concerns about availability of fuels balance of trade and climate change led to the introduction of biofuel programs in the united states brazil europeanunion eu andothercountries the impacts of these programs and the relationship between the food and fuel markets have become major topics of economic research this paper summarizes the main findings of alternative lines of research on the relationship between the food and fuel markets and identifies gaps and quandaries that warrant further research this is not meant to be a complete survey and it emphasizes several of our studies within the broader literature the paper distinguishes between two bodies of literature one on the relationship between food and fuel prices and another on the impact of the introduction of biofuel on commodity food prices while biofuel prices do not seem to affect food commodity prices we explain why the introduction of biofuel does moreover biofuelshavenotbeenthemostdominant contributor to the recent food price inflation and different biofuels have different impacts

peer monitoring and credit markets a major problem for institutional lenders is ensuring that borrowers exercise prudence in the use of the funds so that the likelihood of repayment is enhanced one partial solution is peer monitoring having neighbors who are in a good position to monitor the borrower be required to pay a penalty if the borrower goes bankrupt peer monitoring is largely responsible for the successful financial performance of the grameen bank of bangladesh and of similar group lending programs elsewhere but peer monitoring has a cost it transfers risk from the bank which is in a better position to bear risk to the cosigner in a simple model of peer monitoring in a competitive credit market this article demonstrates that the transfer of risk leads to an improvement in borrowers welfare

the impact of group based credit programs on poor households in bangladesh does the gender of participants matter this paper estimates the impact of participation by gender in the grameen bank and two other group based micro credit programs in bangladesh on labor supply schooling household expenditure and assets the empirical method uses a quasi experimental survey design to correct for the bias from unobserved individual and village level heterogeneity we find that program credit has a larger effect on the behavior of poor households in bangladesh when women are the program participants for example annual household consumption expenditure increases 18 taka for every 100 additional taka borrowed by women from these credit programs compared with 11 taka for men

assessing the impact of us ethanol on fossil fuel markets a structural var approach abstract despite the growing importance of biofuels the effect of biofuels on fossil fuel markets is not fully understood we develop a joint structural vector auto regression var model of the global crude oil us gasoline and us ethanol markets to examine whether the us ethanol market has had any impact on global oil markets the structural var approach provides a unique method for decomposing price and quantity data into demand and supply shocks allowing us to estimate the distinct dynamic effects of ethanol demand and supply shocks on the real prices of crude oil and us gasoline ethanol demand in the us is driven mainly by government support in the form of tax credits and blending mandates shocks to ethanol demand therefore reflect changes in policy more than any other factor in contrast ethanol supply shocks are driven by changes in feedstock prices a principle finding is that a policy driven ethanol demand expansion causes a statistically significant decline in real crude oil prices while an ethanol supply expansion does not have a statistically significant impact on real oil prices this suggests that even though us ethanol market is small the influence of us biofuels policy on the crude oil market is pervasive we also show that ethanol demand shocks are more important than ethanol supply shocks in explaining the fluctuation of real prices of crude oil and us gasoline

a theory of trickle down growth and development this paper develops a model of growth and income inequalities in the presence of imperfect capital markets and it analyses the trickle down effect of capital accumulation moral hazard with limited wealth constraints on the part of the borrowers is the source of both capital market imperfections and the emergence of persistent income inequalities three main conclusions are obtained from this model first when the rate of capital accumulation is sufficiently high the economy converges to a unique invariant wealth distribution second even though the trickle down mechanism can lead to a unique steady state distribution under laissez faire there is room for government intervention in particular redistribution of wealth from rich lenders to poor and middle class borrowers improves the production efficiency of the economy both because it brings about greater equality of opportunity and also because it accelerates the trickle down process third the process of capital accumulation initially has the effect of widening inequalities but in later stages it reduces them in other words this model can generate a kuznets curve

fiscal devolution and dependency public spending devolution in practice is widely seen as more appropriate for addressing varied political aspirations within state boundaries than is tax devolution a drawback is that devolved public spending may be subject to irresistible upward pressure as illustrated by formula drift of the united kingdom devolved administrations by crowding out the private sector such public spending can exacerbate the problem it was originally intended to alleviate when taxpayers do not value increases in government output at least as highly as the private goods and services they must forgo to finance them then the public sector is too large this article estimates a three sector hecksher ohlin model of the economy with the greatest relative rise of the public spending ratio in the united kingdom wales simulation of the model shows a net gain in employment from a 1 cut in income tax matched by a corresponding reduction in government spending this result is consistent with the current level of intergovernme

migration and wage effects of taxing top earners evidence from the foreigners tax scheme in denmark this paper analyzes the eects of income taxation on the international migration and earnings of top earners using a danish preferential foreigner tax scheme and populationwide danish administrative data this scheme introduced in 1991 allows new immigrants with high earnings to be taxed at a preferential at rate for a duration of three years we obtain two main results first the scheme has doubled the number of highly paid foreigners in denmark relative to slightly less paid and therefore ineligible foreigners this translates into a very large elasticity of migration with respect to 1 minus the average tax rate on foreigners between 1 5 and 2 second we nd compelling evidence of a negative eect of the scheme induced reduction in the average tax rate on pre tax earnings of foreign migrants at the individual level this nding can be rationalized by a matching frictions

millionaire migration and taxation of the elite evidence from administrative data a growing number of u s states have adopted millionaire taxes on top income earners this increases the progressivity of state tax systems but it raises concerns about tax flight elites migrating from high tax to low tax states draining state revenues and undermining redistributive social policies are top income earners transitory millionaires searching for lower tax places to live or are they embedded elites who are reluctant to migrate away from places where they have been highly successful this question is central to understanding the social consequences of progressive taxation we draw on administrative tax returns for all million dollar income earners in the united states over 13 years tracking the states from which millionaires file their taxes our dataset contains 45 million tax records and provides census scale panel data on top income earners we advance two core analyses 1 state to state migration of millionaires over the long term and 2 a sharply focused discontinuity anal
