the relationship between farm size and productivity in agriculture evidence from maize production in northern china the relationship between farm size and productivity has long been a topic of debate in development economics using farm level panel data from 2003 to 2013 we investigate the relationship between maize yield and farm size in northern china after controlling for farm specific characteristics we restore a mild u shaped relationship between maize yield and cropping area from the apparent inverse u shaped curve this suggests that an inverse farm size productivity relationship persists for most small sized farms further analyses demonstrate that farmer input choice between labor and capital is likely to smooth the non linear farm size productivity relationship with capital use being more likely to affect the farm size productivity relationship at a larger scale the findings imply that subsidizing farmers to rent land without helping them become better equipped could result in resource misallocation towards larger farms using less efficient labor intensive technologies

how does land fragmentation affect off farm labor supply panel data evidence from china abstract this article provides a deeper theoretical understanding of the linkages between land fragmentation and off farm labor supply in china andinvestigates this relationship empirically in a more direct way than does the existing literature drawing upon a rural household panel data setcollected in zhejiang hubei and yunnan provinces from 1995 to 2002 we estimate the effects in two steps first we estimate the effect of landfragmentation on labor productivity second we estimate the effect of land fragmentation on off farm labor supply the production function resultsshow that land fragmentation indeed leads to lower agricultural labor productivity implying that land consolidation will make on farm work moreattractive and thus decrease off farm labor supply however the effect of land consolidation on off farm labor supply is not signi cant one likelyexplanation for this result may be the potentially imperfect labor markets jel classi cations j22 q15 q24 r23 keywords

a three gap model of foreign transfers and the gdp growth rate in developing countries abstract a simplified macroeconomic framework is developed for the fiscal gap which is considered to be an important stumbling block for adjustment with growth in highly indebted developing countries distinctive characteristics of a fiscally constrained economy are compared with those of economies constrained either by the availability of savings or foreign exchange tentative implications for external conditionality accompanying debt relief measures are derived

can unobserved land quality explain the inverse productivity relationship abstract an inverse relationship between both farm productivity and labor intensity and farm size is a common empirical finding in developing country agriculture the traditional explanation has been imperfect labor markets recently it has been suggested instead that the inverse relationship is a statistical artifact resulting from omitted land quality using a farm level data set from java i investigate whether omitted variable bias can explain the inverse relationship i show that the inverse relationship and accompanying wage responses are inconsistent with a model of neoclassical farm behavior that ignores omitted variable bias instrumental variables techniques yield parameter estimates in which the inverse relationship is eliminated and the estimated wage elasticities are more in line with economic theory further econometric investigation hints that a model of omitted land quality may be a possible source of the inverse relationship these results emphasize the importance of considering the sources of cross sectional variation in estimating microeconomic relationships

land rental development via institutional innovation in rural jiangsu china previous studies have demonstrated that there are two important preconditions for encouraging land rental in agriculture out migration and the enhancement of security and transferability of land rights focusing on the latter we scrutinize the impacts of institutions aimed at facilitating land use dynamism particularly the rural shareholding cooperatives rscs which have been established recently at the local level in rural china in general we find that rscs can pave the way for the extension of property rights to farmland and promote more efficient land use patterns using survey data collected from 300 village committees in rural jiangsu province we estimate the effectiveness of rscs in encouraging land rental our analysis reveals that rscs can serve as intermediate agents for reducing transaction costs associated with exchange of land use rights and thereby not only encourage land rental consolidation activities but also enable the entry of non farm household entities into the farm business

the exchange rate and fiscal consolidation episodes in emerging market economies abstract an analysis of fiscal consolidations in emerging market economies during 1970 2004 suggests that exchange rate depreciation raises the probability of a fiscal consolidation being successful including when controlling for debt growth the composition of the consolidation and degree of democracy

effects of fiscal contractions the importance of preceding exchange rate movements we examine the importance of exchange rate and money supply movements for the macroeconomic outcome of fiscal contractions and find i contractions associated with a favorable macroeconomic outcome have been preceded by significantly higher real depreciations as compared to contractions associated with a less favorable macroeconomic outcome and ii contractions preceded by real depreciations improve expectations about future income and generate higher private consumption growth we discuss policy implications for countries both outside and inside the emu

expansionary fiscal contractions evidence from panel data we examine the ability of the expansionary fiscal contraction efc hypothesis to explain the performance of oecd economies during fiscal crises we find some limited evidence in its favour if public consumption is reduced in response to a fiscal crisis as defined by a high level of debt private consumption does seem to increase however the size of the effect is smaller than that typically found in other studies furthermore the increase in private consumption is usually not sufficient to offset the direct effect of a reduction in public consumption on output fiscal contractions are not literally expansionary

fiscal policy and financial market movements abstract this paper estimates fiscal policy reaction function in order to investigate the links between financial market movements and fiscal policy outcomes an increase in asset prices affects in a positive and significant manner primary balances with the response reflecting both an increase in government revenues and a fall in government spending the most important impact on fiscal balances is due to changes in residential property prices changes in equity and commercial property prices are also important determinants of fiscal balances our findings suggest that the steepening of the slope of the yield curve contributes to expenditure based fiscal discipline

national wage trends and migration in a chinese village economy a micro level modeling approach based on a composite utility function china s economy is experiencing a regime shift away from a fully elastic supply of labor from a large pool of rural surplus labor and toward a situation of increasing labor scarcity and rising wage rates moreover faster wage increases in the regions of origin of many rural urban migrants are likely to affect the dynamics of inter regional migration these wage trends have implications at the local level in particular in a setting in which migration connects rural communities to the national labor market and in which migration is of high importance for the livelihoods of rural households taking a village perspective this article develops a village computable general equilibrium model to study local impacts of current wage trends in china as a central piece of the model the role of access to migration for household livelihoods is recognized access to migration is linked to household demographics and included in the model through a composite utility function that captures household preferences and disutilities associated with alternative off farm activities simulation results illustrate how households utility considerations affect migration responses to national wage changes statements about possible impacts on village level labor supply land use and agricultural production are made when migration wages and local off farm wages are simulated to increase an overall increase in household and village migration and a higher supply of labor to local off farm labor markets is accompanied by a contraction of farm production although land is reallocated between households with different migration responses total agricultural output declines

precautionary behavior migrant networks and household consumption decisions an empirical analysis using household panel data from rural china abstract we develop a test of precautionary behavior in the consumption decisions of rural agricultural households among surveyed households facing a median level of consumption risk 10 of savings can be attributed to a precautionary motive and this increases to 15 for households with consumption per capita below the poverty line we next use distant lags of local rainfall shocks uncorrelated with current consumption growth to identify the size of migrant networks outside the village and then present evidence that both poor and nonpoor households engage in less precautionary saving as the size of the village migrant network increases

the evolution of income inequality in rural china abstract in this article we analyze trends in income inequality and the distribution of income in rural china from 1987 to 1999 we find an uneven but long run increase in inequality in rural china and show that nearly half of the rural population was not much better off in 1999 than at the start of the period we rule out geography as the most important factor for explaining income differences and the increases that occurred over time much more important were growing differences between households living in the same village province or region we also find that access to nonagricultural incomes from local wage employment and family businesses contributes to inequality but that employment outside the county in which a household lives and accessed through temporary migration is relatively equalizing finally we document important strengths and weaknesses of the primary data set used for our analyses relative to other data sources available for study of inequality and poverty in rural china

fiscal stimulus in times of high debt reconsidering multipliers and twin deficits we investigate the impact of fiscal stimuli at different levels of the government debt to gdp ratio for a sample of 17 european countries from 1970 to 2010 this is implemented in an interacted panel var framework in which all coefficient parameters are allowed to change continuously with the debt to gdp ratio we find that responses to government spending shocks exhibit strong nonlinear behavior while the overall cumulative effect of a spending shock on real gdp is positive and significant at moderate debt to gdp ratios this effect turns negative as the ratio increases the total cumulative effect on the trade balance as a share of gdp is negative at first but switches sign at higher levels of debt consequently depending on the degree of public indebtedness our results accommodate long run fiscal multipliers that are greater and smaller than one or even negative as well as twin deficit and twin divergence behavior within one sample and time period from a policy perspective these results lend additional support to increased prudence at high public debt ratios because the effectiveness of fiscal stimuli to boost economic activity or resolve external imbalances may not be guaranteed

output effects of government purchases the theoretical analysis focuses on the distinction between temporary and permanent movements in government purchases under plausible conditions the temporary case involves an output response that is positive less than one to one with the change in government purchases and larger than that generated by an equal sized but permanent shift in purchase the equilibrium real rate of return rise in the temporary case but changes little in the permanent one defense purchases are divided empirically into permanent and temporary components by considering the role of temporary wars no temporary shifts in nondefense purchases were isolated empirical results verify an expansionary output effect for temporary purchases that exceeds that of permanent purchases the results for some other expectational hypotheses are found to be generally supportive of the theory

private debt overhang and the government spending multiplier evidence for the united states using state dependent local projections and historical us data we find that government spending multipliers are considerably larger in periods of private debt overhang in particular while multipliers are below or close to one in low private debt states we find significant crowding in of private spending in periods of debt overhang resulting in multipliers that are much larger than one in high private debt episodes more government purchases even reduce the ratio of government debt to gross domestic product these results are robust for the type of shocks and when we control for the business cycle financial crises deleveraging episodes government debt overhang and the zero lower bound

on measuring the effects of fiscal policy in recessions we do not have a good measure of the effects of fiscal policy in a recession because the methods that we use to estimate the effects of fiscal policy both those using the observed outcomes following different policies in aggregate data and those studying counterfactuals in fitted model economies almost entirely ignore the state of the economy and estimate the government multiplier which is presumably a weighted average of the one we care about the multiplier in a recession and one we care less about the multiplier in an expansion notable exceptions to this general claim sug gest this difference is potentially large our lack of knowledge stems significantly from the focus on linear dynamics vector autoregressions and linearized or close to linear dynamic stochastic general equilibrium dsge models our lack of knowledge also reflects a lack of data deep recessions are few and nonlinearities hard to measure the lack of statistical power in the estimation of nonlinear models using aggregate data can be addressed by exploiting estimates of partial equilibrium responses in disaggregated data microeconomic estimates of the partial equilibrium causal effects of a policy can discipline the causal channels inherent in any dsge model of the general equilibrium effects of policy microeconomic studies can also provide measures of the dependence of the effects of a policy on the states of different agents which is a key component of the dependence of the general equilibrium effects of fiscal policy on the state of the

savings and investment in australia it has become popular to advocate tax reduction on the basis of promoting savings investment and ultimately economic growth the linkage between the variables is argued by various neoclassical growth models and is further suggested by recent studies which highlight the close association between domestic saving and investment rates the close association may allow for polices which alter domestic saving levels in order to alter domestic investment levels this interpretation however presumes an endogenous investment response equally likely theoretically is that the close association is maintained by movements in national savings the present paper explicitly examines the endogeneity of the australian saving and investment rates the results highlight the exogeneity of investment the results further suggest an endogenous response on the part of australia s saving rate the results may limit the potential benefits of these tax changes

missing ness in action selectivity bias in gps based land area measurements land area is a fundamental component of agricultural statistics and of analyses undertaken by agricultural economists while household surveys in developing countries have traditionally relied on farmers own potentially error prone land area assessments the availability of affordable and reliable global positioning system gps units has made gps based area measurement a practical alternative nonetheless in an attempt to reduce costs keep interview durations within reasonable limits and avoid the difficulty of asking respondents to accompany interviewers to distant plots survey implementing agencies typically require interviewers to record gps based area measurements only for plots within a given radius of dwelling locations it is therefore common for as much as a third of the sample plots not to be measured and research has not shed light on the possible selection bias in analyses relying on partial data due to gaps in gps based area measures this paper explores the patterns of missingness in gps based plot areas and investigates their implications for land productivity estimates and the inverse scale land productivity relationship using multiple imputation mi to predict missing gps based plot areas in nationally representative survey data from uganda and tanzania the paper highlights the potential of mi in reliably simulating the missing data and confirms the existence of an inverse scale land productivity relationship which is strengthened by using the complete multiply imputed dataset the study demonstrates the usefulness of judiciously reconstructed gps based areas in alleviating concerns over potential measurement error in farmer reported areas and with regards to systematic bias in plot selection for gps based area measurement

the permanent income hypothesis estimation and testing by instrumental variables the permanent income hypothesis with rational expectation is restated estimated and tested by an instrumental variables technique on the postwar u s aggregate time series data the hypothesis is accepted on a consumption series which includes service flows from consumer durables if the consumption series is the one in the national income and product accounts the hypothesis is decisively rejected an explanation is suggested to reconcile the conflicting test results

the intertemporal evolution of agriculture and labor over a rapid structural transformation lessons from vietnam abstract we combine nationally representative household and labor force survey data from 1992 to 2016 to provide a detailed description of rural labor market evolution and how it relates to the structural transformation of rural vietnam especially within the agricultural sector our study adds to the emerging literature on structural transformation in low income countries using micro level data and helps to answer several policy related questions we find limited employment creation potential of agriculture especially for youth rural urban real wage convergence has gone hand in hand with increased diversification of the rural economy into the non farm sector nationwide and rapid advances in educational attainment in all sectors and regions workforce minimum wage laws seem to have played no significant role in increasing agricultural wages this enhanced integration also manifests in steady attenuation of the longstanding inverse farm size yield relationship farming has remained securely household based and the family farmland distribution has remained largely unchanged small farm sizes have not obstructed mechanization nor the uptake of labor saving pesticides consistent with factor substitution induced by rising real wage rates as rural households rely more heavily on the labor market human capital accumulation rather than land endowments have become the key correlate of improvements in rural household well being

productivity shocks budget deficits and the current account abstract productivity shocks and budget deficits are considered to be two key determinants of the current account in order to assess formally the role of both factors in driving current account movements the present paper extends the standard intertemporal model of the current account to allow for non ricardian household behavior testable cross equation restrictions for the current account and investment are derived by drawing on the distinction between country specific and global innovations to productivity as well as to the government budget we test the restrictions of the model against time series data for 21 oecd countries and find evidence in support of the model

do migrants really save more understanding the impact of remittances on savings in rural china abstract this article studies the impact of remittances on the savings behaviour of rural households in china using a primary survey undertaken by the authors in 2006 allowing for endogeneity and left censoring of remittances we find that the marginal propensity to save out of remittances is well below half of that out of other sources of incomes moreover we find no evidence of any direct effect of remittances on either capital input or gross output of farm production these findings are robust with respect to alternative definition of savings and are in line with recent studies which conclude that remittances are largely used for consumption purposes by rural chinese households

insecurity of property rights and matching in the tenancy market this paper analyzes the functioning of land rental markets in the dominican republic using a new data set collected specifically to characterize the entire market we analyze the choice of the landlords and the tenants in the search for the optimal partner we show how insecure property rights leads to segmentation in the tenancy markets along socio economic group and hence severely limits access to land for the rural poor

did higher inequality impede growth in rural china this paper estimates the relationship between initial village inequality and subsequent household income growth for a large sample of households in rural china using a rich longitudinal survey spanning the years 1987 2002 and controlling for an array of household and village characteristics the paper finds that households located in higher inequality villages experienced significantly lower income growth through the 1990s however local inequality s predictive power and effects are significantly diminished by the end of the sample the paper exploits several advantages of the household level data to explore hypotheses that shed light on the channels by which inequality affects growth biases due to aggregation and heterogeneity of returns to own resources previously suggested as candidate explanations for the relationship are both ruled out instead the evidence points to unobserved village institutions at the time of economic reforms that were associated with household access to higher income activities as the source of the link between inequality and growth the empirical analysis addresses a number of pertinent econometric issues including measurement error and attrition but underscores others that are likely to be intractable for all investigations of the inequality growth relationship

explaining saving investment correlations national saving and investment rates are highly positively correlated in virtually all countries this is puzzling as it apparently implies a low degree of international capital mobility this paper shows that the observed positive correlation between national saving and investment rates arises naturally within a quantitatively restricted equilibrium model with perfect mobility of financial and physical capital the model is consistent with the fact that saving investment correlations are larger for larger countries but are still substantial for small countries further the model is consistent with the finding that current account deficits tend to be associated with investment booms copyright 1993 by american economic association

property rights labour markets and efficiency in a transition economy the case of rural china we investigate the consequences of imperfect factor market development for farm efficiency in north china we estimate the extent to which an inverse relationship in farm productivity can be attributed to the administrative as opposed to market allocation of land combined with unevenly developed off farm opportunities using a new household survey we find considerable inefficiency in the use of labour this inefficiency is alleviated by external labour markets and to a limited degree by administrative reallocations the reallocations do not go far enough however which raises important questions about con straints on rental activity and property rights formation more generally jel classification q15 012

is consumption growth consistent with intertemporal optimization evidence from the consumer expenditure survey in this paper we show that some of the predictions of models of consumer intertemporal optimization are in line with the patterns of nondurable expenditure observed in u s household level data we propose a flexible specification of preferences that allows multiple commodities and yields empirically tractable equations we estimate preference parameters using the only u s micro data set with complete consumption information we show that previous rejections can be explained by the simplifying assumptions made in previous studies we also show that results obtained using good consumption or aggregate data can be misleading

the financial cycle and macroeconomics what have we learnt abstract it is high time we rediscovered the role of the financial cycle in macroeconomics in the environment that has prevailed for at least three decades now it is not possible to understand business fluctuations and the corresponding analytical and policy challenges without understanding the financial cycle this calls for a rethink of modelling strategies and for significant adjustments to macroeconomic policies this essay highlights the stylised empirical features of the financial cycle conjectures as to what it may take to model it satisfactorily and considers its policy implications in the discussion of policy the essay pays special attention to the bust phase which is less well explored and raises much more controversial issues

the impact of government debt on private consumption in oecd countries abstract this paper establishes a non linear relationship between private consumption and government debt in oecd countries with high government debt a fiscal expansion is partly crowded out by a fall in private consumption in contrast in low debt countries private consumption is insensitive to changes in government debt thus fiscal policy is less effective in stabilising business cycle fluctuations at higher levels of government debt

future fiscal and budgetary shocks abstract we study the effects of future tax and budgetary shocks in a non monetary and possibly non ricardian economy an unanticipated temporary labor tax cut to be effective on a given future date a delayed debt bomb causes at once a drop in the unit value placed on the firms business asset the customer with the result that share prices the hourly wage and employment drop in tandem this paradox of reduced activity through announcement of future stimulus does not hinge on an upward jump of long interest rates a future tax rate cut lacking a sunset provision has the same negative effects

land reallocation in an agrarian transition liberalising key factor markets is a crucial step in the transition from a socialist control economy to a market economy however the process can be stalled by imperfect information high transaction costs and covert resistance from entrenched interests the article studies agricultural land reallocation in the wake of vietnam s efforts to establish a free market in land use rights following de collectivisation inefficiencies in the initial administrative allocation are measured against an explicit counterfactual land allocation responded positively but slowly to the initial inefficiencies there is no sign that the transition favoured the land rich or that it was thwarted by local officials vietnam s agrarian transition has closely followed a now classic policy scenario for economies in transition first one privatises the main productive assets in this case agricultural land use rights then one legalises their free exchange in the first step the de collectivisation of vietnam s agriculture meant that the land that had previously been farmed collectively was to be allocated by administrative means across households within each commune without a market mechanism to guide the process it can be expected that inefficiencies in land allocation would remain with some households having too much land relative to a competitive market allocation and some too little ravallion and van de walle 2004 document evidence of such inefficiencies in the initial administrative allocation at the time of de collectivisation

structural factors associated with primary fiscal balances in developing countries the study explores the conditions under which a government in a developing country is likely to run a balanced or surplus budget we contend that primary fiscal deficits are likely to persist where the economy is too saving constrained to raise private sector investment to conduct the investigation a logit model is applied to a sample of developing countries to see whether the saving constraints are associated with the fiscal stance of governments accordingly income level growth external current account balance and foreign direct investment are used as indicators of the saving constraint with the exception of economic growth positive developments in these variables turned out to be significant to the likelihood of the government adopting a surplus budget

the role of macroeconomic instability in public and private capital accumulation and growth the case of turkey 1963 1999 this study investigates the empirical relationship s between macroeconomic instability public and private capital accumulation and growth in turkey over the period 1963 1999 time series econometric techniques such as cointegration and impulse response analysis are used the results of this paper suggest that the chronic and increasing macroeconomic instability of the turkish economy has seriously affected her capital formation and growth furthermore the turkish experience indicates that chronic macroeconomic instability seems to be a serious impediment to public investment especially to its infrastructural component and shatters or even reverses the complementarity between public and private investment in the long run

searching for non linear effects of fiscal policy evidence from industrial and developing countries several recent studies suggest that the response of national saving to scal policy may be non linear in this paper we use two data sets to search for the circumstances in which such non linear response may arise a sample of oecd countries already used in previous studies and a sample of developing countries using more recent world bank data we nd that in both samples non linear e ects tend to be associated with large and persistent scal impulses in the oecd sample the non linearity of the response is stronger for scal contractions than for expansions an increase in net taxes has no e ect on national saving during large scal contractions while it has a positive e ect in less pronounced contractions high or rapidly growing public debt does not appear to be a good predictor of non linear e ects in the world bank sample of developing countries non linearities in the response national saving to scal policy are not limited to large scal contractions and also tend to occur in periods in which debt is accumulating rapidly regardless of its initial level 2000 elsevier science b v all rights reserved jel classixcation e21 e62 h31

estimating saving investment correlations evidence for oecd countries based on an error correction model abstract saving investment correlations are important stylized facts in open economy macroeconomics and indicators of capital mobility they are best estimated by an error correction model ecm because an ecm is consistent with intertemporal general equilibrium models the ecm is a synthesis of previous approaches applying the ecm to the oecd countries we find that in general saving and investment are cointegrated the ecm is more powerful in detecting cointegration than the two step engle granger procedure estimates of the saving investment correlation are robust with respect to overdifferencing we find evidence of a large country effect and an increase in capital mobility within the oecd area

price distortions and resource use efficiency in indian agriculture a restricted profit function approach this paper develops a generalized profit function that incorporates price distortions resulting from imperfect market conditions sociopolitical and institutional constraints as well as technical and allocative inefficiency the model is applied to test 1 the appropriateness of the neoclassical profit function and 2 the effect of education and farm size on allocative performance using farm level data from indian agriculture empirical results reject the neoclassical profit maximization hypothesis based on market prices in favor of the general model with price distortions and therefore help to improve allocation of inputs and output farm size is found to reduce price distortions only for small farmers copyright 1992 by mit press

fiscal policy and national saving this paper uses structural vector autoregressions along with structural measures of fiscal policy to measure the dynamic impact of fiscal policy shocks on the output gap and national saving positive shocks to government purchases and negative shocks to real net taxes are found to increase the output gap positive shocks to the government s structural surplus increases national saving although the effects are small positive shocks to government purchases are found to substantially reduce national saving negative shocks to real net tax revenues as a share of potential gdp have a small negative impact on national saving

rural reforms and agricultural growth in china this paper employs province level panel data to assess the contributions of decollectivization price adjustments and other reforms to china s agricultural growth in the reform period decollectivization is found to improve total factor productivity and to account for about half of the output growth during 1978 84 the adjustment in state procurement prices also contributed positively to output growth its impact came mainly from the responses in input use the effect of other market related reforms on productivity and output growth was very small reasons for slowdown in agricultural growth after 1984 are also analyzed copyright 1992 by american economic association

missing women and the price of tea in china the effect of sex specific earnings on sex imbalance economists have long argued that the sex imbalance in developing countries is caused by underlying economic conditions this paper uses exogenous increases in sex specific agricultural income caused by post mao reforms in china to estimate the effects of total income and sex specific income on sex differential survival of children increasing female income holding male income constant improves survival rates for girls whereas increasing male income holding female income constant worsens survival rates for girls increasing female income increases educational attainment of all children whereas increasing male income decreases educational attainment for girls and has no effect on boys educational attainment

household composition labor markets and labor demand testing for separation in agricultural household models this paper tests the separation of farm labor supply and labor demand decisions using the observation that household composition is an important determinant of farm labor use with nonseparation after assessing the conditions under which the test has power against several alternatives an empirical model is developed to test the proposition that farm employment is independent of family composition the model is estimated on a data set from rural java the null hypothesis that farm labor allocation decisions are independent of household structure is not rejected the results are robust to different specifications of the labor demand function copyright 1992 by the econometric society

government spending and private consumption some international evidence this paper investigates the relationship between private consumption and publicly provided goods and services for a number of countries the empirical results show that in the aggregate private and government consumption are best described as complementary in the sense that an increase in one raises the marginal utility of the other the strength of this relationship is shown to be negatively affected by the government size these findings are robust across all specifications tried copyright 1994 by ohio state university press

gender agricultural production and the theory of the household virtually all models of the household assume that the allocation of resources is pareto efficient within many african households agricultural production occurs on many plots controlled by different members of the household pareto efficiency implies that factors should be allocated efficiently across these plots i find in contrast that plots controlled by women are farmed much less intensively than similar plots within the household controlled by men the estimates imply that about 6 percent of output is lost because of inefficient factor allocation within the household the paper suggests a new approach to modeling intrahousehold allocation consistent with the empirical results

the effects of well management and the nature of the aquifer on groundwater resources we compare groundwater use under collective well management in china where village leaders allocate water among households and under private well management where farmers either pump from their own wells or buy water from wells owned by other farmers villages are divided into connected or isolated groups depending on whether there are lateral groundwater flows between aquifers underlying a village and neighboring ones in rural china households under collective well management use less water even under collective management households located in connected villages use more water indicating that the connectedness of the aquifers may undermine leaders incentives to conserve water

wage growth landholding and mechanization in chinese agriculture this paper uses farm panel data from china to examine the dynamics of land transactions machine investments and the demand for machine services recently china s agriculture has experienced a large expansion of machine rentals and machine services provided by specialized agents which has contributed to mechanization of agricultural production the empirical results show that an increase in nonagricultural wage rates leads to expansion of self cultivated land size a rise in the proportion of nonagricultural income or the migration rate also increases the size of self cultivated land interestingly however relatively educated farm households decrease the size of self cultivated land which suggests that relatively less educated farmers tend to specialize in farming the demand for machine services has also increased if agricultural wage and migration rate increased over time especially among relatively large farms the results on crop income support the complementarity between rented in land and machine services demanded which implies that scale economies are arising in chinese agriculture with mechanization and active land rental markets

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

migration and incomes in source communities a new economics of migration perspective from china the objective of this paper is to understand the effects of china s migration on source communities and to discuss their policy implications we draw from new economics of labor migration nelm theory to understand how migration and migrant remittances can relax or tighten market constraints in china s rural economy using simultaneous equation econometric techniques and household survey data from china we estimate net sectorspecific effects of migration on rural household income focusing on farm production and self employment our econometric findings indicate that the loss of labor to migration has a negative effect on household cropping income in source areas however we provide evidence that remittances sent home by migrants positively compensate for this lost labor effect contributing to household incomes directly and indirectly by stimulating crop and possibly self employment production this finding offers evidence in support of the nelm hypothesis that remittances loosen constraints on production in the imperfect market environments characterizing rural areas in less developed countries taking into account both the multiple effects of migration and the change in household size participating in migration increases household per capita income between 14 and 30 percent migration and incomes in source communities a new economics of migration perspective from china china is experiencing the largest peacetime flow of labor out of agriculture ever witnessed in world history solinger 1999 rozelle et al 1999 despite the rapid expansion of labor migration china s work force is still disproportionately employed in agriculture compared to other countries at similar levels of per capita gdp taylor and martin 2001 hence as china s economy continues to expand the flow of labor to urban areas will continue and even accelerate johnson 1999 the massive flow of labor away from farms has intensified research interest in china s migration in recent years however as in the broader literature on migration in less developed countries most recent studies on china s migration have focused on determining the size and composition of the labor flow macroeconomic implications of increased migration and the effects of migration on urban areas zhao 1999 yang 1999 1997 less emphasis has been placed on researching the effects of migration on the rural communities that migrants leave even though evidence shows that the rural household in the village of origin is typically the central concern of all those involved in migration both those who leave and those who stay behind exceptions include wang and zuo 1999 bai 2001 moreover the recent increase in migration has left policy makers particularly concerned regarding the way source communities will be affected moa 1999 they are concerned that as labor flows away from farms food production and crop income will decline potentially threatening china s food security furthermore policy makers are concerned about the increasing gap between urban and rural household incomes if migration exacerbates this gap some fear that as it grows rural residents eventually will flood cities ill equipped to absorb them others fear that discontent over a rising urban rural income gap could even spill over into political unrest yang 1999 because china s markets and other modern economic institutions are still relatively undeveloped migration may play a pivotal role in creating or overcoming constraints caused by the lack of well functioning markets and or institutions knight and song 1999 benjamin and brandt 2000 the new economics of labor migration nelm literature analyzes migration as a household decision rather than as an individual decision stark 1991 the nelm hypothesizes that rural households facing imperfect market environments decide

effects of austerity expenditure and tax based approaches we review the debate surrounding the macroeconomic effects of deficit reduction policies austerity the discussion about austerity in general has distracted commentators and policymakers from a very important result namely the enormous difference on average between expenditure and tax based austerity plans spending based austerity plans are remarkably less costly than tax based plans the former have on average a close to zero effect on output and lead to a reduction of the debt gdp ratio tax based plans have the opposite effect and cause large and long lasting recessions these results also apply to the recent episodes of european austerity which in this respect were not especially different from previous cases

moving toward markets labor allocation in rural china abstract china s economic reforms have brought rapid growth in rural off farm employment raising questions about the assumption that rural china is labor surplus and has poorly functioning factor markets we investigate this by testing for separability between household labor demand and supply using panel data we find that separability is rejected overall indicating that factor markets remain underdeveloped nonseparability however is associated with labor surplus in some areas and labor shortage in others moreover separability holds where substantial employment opportunities exist in the wider township suggesting that such employment promotes competitive allocation within villages as well as the inter village movement of resources

austerity and private debt this study provides empirical evidence that the costs of austerity crucially depend on the level of private indebtedness in particular fiscal consolidations lead to severe contractions when implemented in high private debt states contrary fiscal consolidations have no significant effect on economic activity when private debt is low these results are robust to alternative definitions of private debt overhang the composition of fiscal consolidations and controlling for the state of the business cycle and government debt overhang i show that deterioration in household balance sheets is important to understand private debt dependent effects of austerity

habit formation adjustment costs and international transmission of fiscal policy abstract the paper studies the effects of fiscal policy in an integrated world economy the setup is one with habit forming endogenous rates of time preference and adjustment costs in investment most of the predictions of the model are in line with the recent empirical literature on fiscal policy for instance in response to a balanced fiscal expansion we obtain positive long run output multipliers long run increases in employment short and medium run increases in wages and decreases in investment our results suggest that short run government spending multipliers are smaller than tax multipliers most importantly we show that the model can generate positive short and medium run consumption responses to a positive fiscal shock this is relevant as negative consumption responses are considered to be one of the main challenges facing neo classical models of fiscal policy

government size and unemployment evidence from industrial countries using data from 19 industrial countries for the period 1985 to 2002 this paper analyzes how the size of the government sector affects unemployment controlling for the impact of the business cycle as well as for the impact of all major labor market institutions and unobserved country effects we find that a large government sector is likely to increase unemployment it appears to have a particularly detrimental effect on women and the low skilled and to substantially increase long term unemployment it seems that dominant stateowned enterprises a large share of public investment in total investment as well as high top marginal income tax rates and low income threshold levels at which they apply are particularly detrimental

fiscal policy in good times and bad in the 1980s several countries with large government debt or deficit implemented substantial and in some cases drastic deficit cuts contrary to widespread expectations in many cases private consumption boomed rather than contracted this paper shows that in times of fiscal stress shocks to government revenues and especially expenditure have very different effects on private consumption than in normal times

shadow wages and peasant family labour supply an econometric application to the peruvian sierra a striking feature of developing economies is the large proportion of the work force that is self employed lack of widespread labor market participation in the agricultural sector can pose a major obstacle to the empirical implementation of economic models of the peasant household whether because wage data are simply not available or because the assumptions required to make use of wage data stretch the bounds of credulity this paper develops a methodology for estimating a structural labor supply model for primarily self employed peasant households which holds under a general agricultural technology and set of labor market conditions the unique feature of the approach is that the opportunity cost of time or shadow wage of household workers is explicitly estimated from an agricultural production function and is subsequently used to identify a set of structural labor supply parameters recent household survey data from rural peru is employed to estimate and perform various diagnostic tests on the model the empirical findings lend support to the hypothesis that peasant households allocate their members time as if to maximize a family utility function and moreover demonstrate the tractability of the shadow wage methodology and its usefulness in estimating more elaborate time allocation models

rising real wages mechanization and growing advantage of large farms evidence from indonesia this paper examines dynamic patterns of land use capital investments and wages in agriculture using farm panel data from indonesia the empirical analysis shows that with an increase in real wages that prevailed in both agricultural and non agricultural sectors in rural areas relatively larger farmers increased the size of operational farm land by renting in land as well as used more hired in machines through machine rental and or service providers which induces the substitution of labor by machines machines and land are complementary and consistently the inverse farm size productivity relationship tends to be reversed among relatively large holders the results support growing diminishing advantage of large small farms in the presence of rapidly rising real wages and have food security policy implications to many asian countries where real wages are rapidly rising and small farms are predominant

the potential of land rental markets in the process of economic development evidence from china abstract we develop a model of land leasing with agents characterized by unobserved heterogeneity in ability and presence of an off farm labor market in this case decentralized land rental may contribute to equity and efficiency goals and may have several advantages over administrative reallocation the extent to which this is true empirically is explored using data from three of china s poorest provinces land rental markets and administrative reallocation reallocate land to those with lower endowments but the former are more effective in doing so and have a bigger productivity enhancing effect information on hypothetical market participation suggests that reducing transaction costs in land rental markets could help to realize significant additional productivity gains

village political economy land tenure insecurity and the rural to urban migration decision evidence from china this paper investigates the impact of land tenure insecurity on the migration decisions of china s rural residents a simple model first frames the relationship among these variables and the probability that a reallocation of land will occur in the following year after first demonstrating that a village leader s support for administrative land reallocation carries with it the risk of losing a future election the paper exploits election timing and village heterogeneity in lineage group composition and demographic change to identify the effect of land security in response to an expected land reallocation in the following year the probability that a rural resident migrates out of the county declines by 2 8 percentage points which accounts for 17 5 percent of the annual share of village residents aged 16 to 50 who worked as migrants during the period this finding underscores the potential importance of secure property rights for facilitating labor market integration and the movement of labor out of agriculture

fiscal adjustments and economic performing a comparative study the empirical relationship among fiscal contractions permanent improvement in public finances and short run economic performance is examined using a sample of 14 european countries over the last three decades the actual experience of policy making has taught that only the adjustments that relied heavily on primary expenditure cuts and were implemented over a relatively long time span were able to achieve a long lasting reduction of public liabilities indeed during these consolidations tax increase amounted to a small fraction of the total adjustment furthermore though they unfolded over a longer period with respect to the unsuccessful ones the overall budget cut was not larger as regards the macroeconomic impact successful episodes tended to be associated with improved economic performance during the adjustment period and in the following two years the economies experienced strong consumption and investment growth reduced unemployment better international competitiveness and falling interest

nominal interest rates consumption booms and lack of credibility a quantitative examination abstract exchange rate based stabilization programs in chronic inflation countries have often been accompanied by an initial expansion of private consumption followed by a contraction this consumption cycle has been attributed to lack of credibility in the sense that the public views the reduction in the devaluation rate as temporary this paper assesses the quantitative relevance of the temporariness hypothesis by comparing the predictions of a simple model to the actual figures for seven major programs the paper concludes that nominal interest rates must fall substantially for the temporariness hypothesis to account for an important fraction of the observed consumption booms

voting on the budget deficit this paper analyzes a model in which a group of rational individuals votes over the composition and time profile of public spending all voters agree that a balanced budget is ex ante optimal however if there is disagreement between current and future majorities a balanced budget is not a political equilibrium under majority rule under certain conditions a majority of the voters favors a budget deficit and the equilibrium deficit is larger the greater is the polarization among voters copyright 1990 by american economic association

fiscal multipliers in recessions standard business cycle models have difficulties generating large state dependent fiscal multipliers employing a model of costly financial intermediation based on curdia woodford we show that fiscal multipliers can be strongly state dependent fiscal expansions during recessions may lead to multiplier values exceeding two while similar expansions during economic booms would produce values falling short of unity this pattern obtains if the spread the financial friction is more sensitive to fiscal policy during recessions than during expansions a feature that is present in the data our results are consistent with recent empirical work documenting the state contingency of multipliers

non farm activity household expenditure and poverty reduction in rural vietnam 2002 2008 summary diversifying into non farm activities has been suggested as an effective way out of poverty for rural households in developing countries using the vietnamese household living standards surveys of 2002 2004 2006 and 2008 we test this claim and investigate the effect of non farm sector involvement on poverty and expenditure growth our endogeneity corrected estimates show that an additional household member involved with non farm activity reduces the probability of poverty by 7 12 and increases the household expenditure by 14 over a two year period our findings also indicate that non farm involvement reduces the hours worked on farm but not the household agricultural income

credit constraints cyclical fiscal policy and industry growth this paper evaluates whether the cyclical pattern of fiscal policy can affect growth we first build a simple endogenous growth model where entrepreneurs can invest either in short run projects or in long term growth enhancing projects long term projects involve a liquidity risk which credit constrained firms try to overcome by borrowing on the basis of their short run profits by increasing firms market size in recessions a countercyclical fiscal policy will boost investment in productivity enhancing long term projects and the more so in sectors that rely more on external financing or which display lower asset tangibility second the paper tests this prediction using rajan and zingales 1998 s diff and diff methodology on a panel data sample of manufacturing industries across 17 oecd countries over the period 1980 2005 the evidence confirms that the positive effects of a more countercyclical fiscal policy on value added growth productivity growth and r d expenditure are indeed larger in industries with heavier reliance on external finance or lower asset tangibility

testing whether unemployment represents intertemporal labour supply behaviour in the lucas rapping 1969 model of the labour market fluctuations in unemployment represent individuals optimally adjusting their labour supply behaviour in response to fluctuations in wage rates over the business cycle in this paper i propose and implement a misspecification test of the lucas rapping treatment of unemployment as labour supply behaviour using panel data this test extends previous such work with micro data by simultaneously allowing for intertemporal substitution uncertainty and endogenous unemployment using the standard specification of intertemporal labour supply behaviour i find strong evidence against this interpretation of unemployment there are two possible interpretations of the test results the first is that it is necessary to turn to alternative models of the labour market in which unemployed workers are off a supply function the second is that the test results indicate the necessity of moving to more complex models of intertemporal substitution however given current econometric techniques and data sets these alternative models of intertemporal substitution will be extremely difficult to test

estimating fiscal multipliers news from a non linear world we estimate non linear vars to assess to what extent fiscal spending multipliers are countercyclical in the us we deal with the issue of non fundamentalness due to fiscal foresight by appealing to sums of revisions of expectations of fiscal expenditures this measure of anticipated fiscal shocks is shown to carry valuable information about future dynamics of public spending results based on generalised impulse responses suggest that fiscal spending multipliers in recessions are greater than one but not statistically larger than those in expansions however non linearities arise when focusing on extreme events that is deep recessions versus strong expansionary periods

migrant labor markets and the welfare of rural households in the developing world evidence from china in this paper the authors examine the impact of reductions in barriers to migration on the consumption of rural households in china the authors find that increased migration from rural villages leads to significant increases in consumption per capita and that this effect is stronger for poorer households within villages household income per capita and non durable consumption per capita both increase with out migration and increase more for poorer households the authors also establish a causal relationship between increased out migration and investment in housing and durable goods assets and these effects are also stronger for poorer households the authors do not find robust evidence however to support a connection between increased migration and investment in productive activity instead increased migration is associated with two significant changes for poorer households increases both in the total labor supplied to productive activities and in the land per capita managed by the household in examining the effect of migration we pay considerable attention to developing and examining our identification strategy

explaining agricultural and agrarian policies in developing countries the paper describes and as far as possible explains variations in policies programs and institutions that influence agricultural growth agrarian relations and rural welfare across developing countries and over time it evaluates the impact of distorted policy patterns on agricultural production and rural poverty and identifies conditions under which policy reforms meant to bring about greater efficiency and equity are likely to be initiated and sustained it draws upon a broad range of literature to show how material conditions missing markets and government policies affect static welfare outcomes patterns of accumulation state formation and the establishment of political institutions it suggests ways to improve policy advice and proposes directions for future research

moving off the farm land institutions to facilitate structural transformation and agricultural productivity growth in china agriculture has made major contributions to china s economic growth and poverty reduction but the literature has rarely focused on the institutional factors that might underpin such structural transformation and productivity this paper aims to fill that gap drawing on an 8 year panel of 1 200 households in six key provinces it explores the impact of government land reallocations and formal land use certificates on agricultural productivity growth as well as the likelihood of households to exit from agriculture or send family members to the non farm sector it finds that land tenure insecurity measured by the history of past land reallocations discourages households from quitting agriculture the recognition of land rights through formal certificates encourages the temporary migration of rural labor both factors have a large impact on productivity at about 30 percent each mainly by encouraging market based land transfers a sustained increase in non agricultural opportunities will likely reinforce the importance of secure land tenure which is a precondition for successful structural transformation and continued economic attractiveness of rural areas

fiscal policy and occupational employment dynamics we document substantial heterogeneity in occupational employment dynamics in response to government spending shocks in the united states employment rises most strongly in service sales and office pink collar occupations by contrast employment in blue collar occupations is hardly affected by fiscal policy we provide evidence that occupation specific changes in labor demand are key for understanding these findings we develop a business cycle model that explains the heterogeneous occupational employment dynamics as a consequence of composition effects due to heterogeneous employment changes across industries and occupation specific within industry employment shifts due to differences in the short run substitutability between labor and capital services across occupations

induced institutional change or transaction costs the economic logic of land reallocations in chinese agriculture abstract the communal land rights system in china which combines individualised farming with periodic land reallocations provides a good case for testing the economic logic of land reallocations analysis of the results of a unique village survey reveals that a village s choice of land reallocation type partial or large in scale is significantly affected by transaction cost considerations which vary according to village topography and size rather than concerns for economic efficiency tenure security the latter of which is a proxy for the theory of induced institutional change more specifically villages with complex topographies tend to favour partial land reallocation whereas larger settlements tend to reallocate land more thoroughly

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

land allocation in vietnam s agrarian transition while liberalizing key factor markets is a crucial step in the transition from a socialist control economy to a market economy the process can be stalled by imperfect information high transaction costs and covert resistance from entrenched interests the authors study land market adjustment in the wake of vietnam s reforms aiming to establish a free market in land use rights following de collectivization inefficiencies in the initial administrative allocation are measured against an explicit counterfactual market solution the authors tests using a farm household panel data set spanning the reforms suggest that land allocation responded positively but slowly to the inefficiencies of the administrative allocation they find no sign that the transition favored the land rich or that it was thwarted by the continuing power over land held by local officials
