the dynamic cost and persistence of asset inequality in an agrarian economy abstract a growing literature suggests that asset inequality can be economically costly in the presence of agency costs that constrain labor and capital markets unclear in this literature is whether asset markets and optimal individual accumulation of self finance capacity suffice to eliminate costly inequality over time this paper uses numerical dynamic programming methods to explore this question with a model of an initially inegalitarian agrarian economy while an egalitarian asset distribution emerges over time the process involves sufficiently great productivity losses along the way that a redistributive policy could improve on the market s performance by both equity and efficiency criteria

conceptual framework for regional competitiveness budd l and hirmis a k 2004 conceptual framework for regional competitiveness regional studies38 1007 1020 the concept of territorial competitiveness has gained ground in academic policy and practitioner circles in particular urban competitiveness has generated a large literature however there is a danger that competitiveness at a territorial level becomes a conceptual chimera the essential problem is that territorially based actors and agencies seek to position and maintain the utility of their regions and subregions by reference to a set of measures and indicators that are conceptually suspect and often empirically weak the degree to which regions compete depends on a manifold set of factors the paper proposes a conceptual framework for regional competitiveness based on combining the competitive advantage of firms and the comparative advantage of a regional economy the conceptual transmission mechanism to regional competitiveness combines liebenstein s theory of x inefficiency and aggl

making sense of the competitiveness debate the debate over national competitiveness is marked by some basic misperceptions with few exceptions those who use the term have a crude essentially mercantilist view of world trade in which competition among nations is just like competition between corporations not only do the authors and readers of reports on national competitiveness usually not understand comparative advantage they are unaware of the most basic adding up constraints economists however find it hard to believe that seemingly well informed people can really be this naive and assume that there must be more sophisticated ideas lying behind what they say the rationales offered by economists in turn offer false comfort to the would be sophisticates who like the term competitiveness they believe that they have transcended conventional economic theory when the fact is that they have failed to comprehend it in short the actual level of discussion is lower than any of the participants imagines copyright 1996 by oxford university press

asset prices asset stocks and rational expectations abstract this paper explores the relationship between asset return covariances and the impact of asset stock changes on asset prices in the process the paper reconciles recent contradictory results on the effect of changes in the stock of government debt on equity prices a solution for asset prices in a rational expectations equilibrium is also derived this solution has the property that at the prices implied by the solution the demand for each asset equals its supply and the distribution of future asset prices implied by the solution is identical to the distribution upon which asset holders base their demands

the impact of globalisation on different social groups competitiveness social cohesion and spatial segregation in istanbul the main objective of this paper is to explore relations between competitiveness and social cohesion in istanbul it mainly questions whether it is possible to expect a positive change in socio spatial inequalities if increasing competitiveness generates not only international business and high level services but also traditional low cost production activities the findings show that competition in different types of activities has generated large numbers of jobs but has not been able to overcome existing income disparities the increasing income differences however do not mean an increase in socio spatial segmentation since the non market processes and policies related to education gender and the urban land and housing markets have played important roles in the redistribution of different social groups within urban space in addition to the endogenous dynamics of labour markets

upgrading in global value chains lessons from latin american clusters it has been shown that clustering helps local enterprises in industrial districts overcome growth constraints and compete in distant markets in advanced and less developed countries nevertheless recent contributions have stressed that more attention needs to be paid to external linkages and to the role played by global buyers to foster upgrading at cluster levels in this study we contribute to this debate focusing on the analysis of the relationships existing between clustering global value chains upgrading and sectoral patterns of innovation in latin america we find that sectoral specificities matter and influence the mode and the extent of upgrading in clusters integrated in global value chains

on the concept of territorial competitiveness sound or misleading in an era of globalisation the issue of territorial competitiveness is of increasingly central importance for regional development policies this paper aims to deal directly with the issue from a theoretical viewpoint in particular examining two related questions more thoroughly the question of the soundness of the concept of territorial competitiveness itself in terms of economic theory and the question of the new foundations on which this competitiveness is based using a cognitive evolutionary type approach

local versus global separability in agricultural household models the factor price equalization effect of land transfer rights commonly employed global tests for separability between production and consumption decisions are theoretically inappropriate when the market failures creating non separabilities differentially constrain some but not all households simulated maximum likelihood estimates using chinese panel data reject the restrictions implied by a global separability test in favor of regime specific or local separability tests the estimates also show that a global approach to separability obscures the significant effect that less encumbered land transfer rights would have on shadow factor price equalization across households and allocative efficiency the findings on transfer rights suggest a resolution to the debate in china on further property rights reform copyright 2002 oxford university press

competitiveness indices and developing countries an economic evaluation of the global competitiveness report developing countries policy makers worry about national competitiveness and closely watch indices ranking international competitive performance this paper analyzes from a development economics perspective if competitiveness is a legitimate concern and if the leading indices deserve the attention they get it assesses the best known index the global competitiveness report of the world economic forum and finds deficiencies at several levels its definitions are too broad the approach biased and the methodology flawed many qualitative measures are vague redundant or wrong these weak theoretical and empirical foundations reduce the value of the indices for analytical or policy purposes

economic relationship between access to land and rural poverty in nepal in the present socio economic structure of nepal land is the main source of income and consumption for the majority of nepalese this study analyses the economic relationship between access to land and poverty in nepal by establishing the link between land and consumption as well as land and income a generalised additive model gam and ordinary least squares ols demonstrate that greater access to land increases income and consumption of the household and thereby reduces poverty the significant marginal value of land for both consumption and income implies that an effective land reform policy could well be an effective approach to alleviate rural poverty however land reform must come as part of a larger overhaul cluster analysis shows that land reform should target appropriate subgroups within the community in order to differentiate those who would make use of the extra land from those who would not and apply appropriate strategies to each subgroup it reveals the importance of subgroups in determining an appropriate strategy for tackling poverty

interest rate volatility and monetary policy in october 1979 the federal reserve shifted from an interest rate oriented operating procedure to a reserves oriented procedure it is argued in this paper that part of the very large increase in interest rate volatility which resulted from the policy switch may have been due to shifts in the parameters of the money demand equation shifts due to the adoption of a reserve aggregates operating procedure this result is derived by comparing rational expectations equilibria in a simple theoretical model under alternative policy rules this allows the variance of interest rates to be explicitly expressed as a function of the policy rule this abstract was borrowed from another version of this item

risk and insurance in a rural credit market an empirical investigation in northern nigeria credit contracts play a direct role in pooling risk between households in northern nigeria repayments owed by borrowers depend on realizations of random shocks by both borrowers and lenders the paper develops two models of state contingent loans the first is a competitive equilibrium in perfectly enforceable contracts the second permits imperfect information and equilibrium default estimates of both models indicate that quantitatively important state contingent payments are embedded in these loan transactions but that a fully efficient risk pooling equilibrium is not achieved the research is based on a year long survey in zaria nigeria conducted by the author

access to capital and its impact on agrarian structure and productivity in kenya access to capital and its distribution across agents can profoundly shape the structure and performance of an agrarian market economy it is conceptually useful to distinguish between ex ante and ex post capital access ex ante capital access denotes the ability of agents to finance production costs e g labor and purchased inputs costs which must be paid ex ante that is prior to the actual realization of production ex post capital access that is access to capital after the realization of the production process is of particular importance as an insurance substitute in low income agrarian economies where contingency markets are imperfect buoyant ex post capital access would permit an individual to stabilize consumption year to year even as production fluctuates annually a number of theoretical models have ex

household consumption smoothing through ethnic ties evidence from cote d ivoire abstract this paper investigates the hypothesis that households in cote d ivoire take part in spatially diversified risk sharing arrangements with members of their own ethnic group empirical tests are presented using several estimation methods to deal with heteroscedasticity measurement error and extreme value problems to examine whether results are robust across estimation procedures the hypothesis of complete risk sharing within ethnic groups is rejected however there appears to be some partial insurance performed by individual households with other members of the same ethnic group particularly for the households residing in the regions least likely to have access to formal financial arrangements

agrarian structure and agricultural practice typology and application to western sudan a typology of models that explain patterns of variation in farm endowments and farm practices and yields shows that insecurity in renting land financing constraints and the absence of insurance generate patterns of factor use quite different from the famous inverse relationship caused by labor supervision problems one might expect to observe positive relationships between wealth and yields village level data from western sudan confirm that such positive relationships are not a theoretical curiosity wealthy farmers have higher levels of output per hectare because they use more labor per hectare insurance and financing constraints appear to be the crucial market failures

speculative intensity and spot and futures price variability this paper develops a simultaneous stochastic rational expectations model of futures and spot price determination using the model we find that increases in what we term speculative intensity increase spot price variability arising from storage cost shocks but decrease spot price variability arising from demand shocks in contrast increases in speculative intensity unambiguously decrease futures price variability regardless of the underlying source of disturbances we are able to develop these comparative static results because the model has a unique equilibrium

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 distributive impact of land markets in uganda abstract this article presents first hand evidence about land distribution and the impact of land markets in central uganda this area is characterized by unequal distribution of land inheritance rural rural migration and active land markets we show that land markets and particularly land purchases tend to reduce the initial inequality in the initial inherited distribution of land land purchases by landless farmers in their native village represent an important part of this adjustment

monetary policy in a cash in advance economy employment capital accumulation and the term structure of interest rates in this paper we study the effects of monetary policies on employment capital accumulation consumption and the term structure of interest rates in a cash in advance economy where money is required for consumption expenditures monetary policy involves targeting the inflation rate the detailed dynamics of the model are fully worked out as no numerical analysis is involved we are able to identify very clearly the different channels through which monetary policy will impinge on the important macroeconomic variables the model is also used to discuss the great canadian

measuring the national competitiveness of southeast asian countries national competitiveness is a measure of the relative ability of a nation to create and maintain an environment in which enterprises can compete so that the level of prosperity can be improved this paper proposes a methodology for measuring the national competitiveness and uses the 10 southeast asian countries for illustration the basic idea is to deconstruct the complicated concept of national competitiveness to measurable criteria the observations data on the criteria are then aggregated according to their importance to obtain an index of national competitiveness for data collected from questionnaire surveys a calibration technique has been devised to alleviate bias due to personal prejudice in data aggregation the importance is expressed by both a priori weights and a posteriori weights these two types of weights consistently show that singapore malaysia and thailand have the highest national competitiveness while myanmar cambodia and laos are the least competitive countries the performance of each country in every criteria measured also provides directions for these countries to make improvements and for investors to allocate resources

an efficient nonmarket institution under imperfect markets labor sharing for tropical forest clearing this article examines the substitutability efficiency and evolution of an important nonmarket institution in agrarian societies labor sharing from analyses of field level data on forest clearing through time among shifting cultivators in the peruvian amazon we find 1 no productivity difference and unitary elasticities of substitution among family hired and cooperative labor i e perfect substitutes 2 the combination of labor market and sharing makes total labor use unconstrained by household and network endowments i e efficient labor allocation and 3 as labor composition is constrained by network endowments and liquidity credit policies alter not only labor composition but also network formation

the relation between farm size and farm productivity the role of family labor supervision and credit constraints abstract the paper shows that if the performance of hired farmhands is affected by supervision from family members and if the availability of credit is dependent on the amount of land owned then a systematic positive or negative relationship between per acre yields and farm size will prevail a model with no supervision effects on labor productivity would predict that yields are unaffected by farm size the paper also investigates the relation between land utilization and owned holding size when land rental possibilities are limited results are shown to be compatible with various observed patterns in ldcs

wealth weather risk and the composition and profitability of agricultural investments despite the growing evidence that farmers in low income environments are risk averse there has been little empirical evidence on the importance of risk in shaping the actual allocation of production resources among farmers differentiated by wealth the authors use panel data on investments in rural india to examine how the composition of productive and nonproductive asset holdings varies across farmers with different levels of total wealth and across farmers facing different degrees of weather risk income variability is a prominent feature of the experience of rural agents in low income countries the authors report evidence based on measures of rainfall variability that the agricultural investment portfolio behavior of farmers in such settings reflects risk aversion due evidently to limitations on consumption soothing mechanisms such as crop insurance or credit markets the authors results suggest that uninsured weather risk is a significant cause of lower efficiency and lower average incomes a one standard deviation decrease in weather risk measured by the standard deviation of the timing of the rainy season would raise average profits by up to 35 percent among farmers in the lowest wealth quartile moreover rainfall variability induces a more unequal distribution of average incomes for a given distribution of wealth wealthier farmers are willing to absorb significant risk without giving up profits to reduce production risk smaller farmers have to invest their limited wealth in ways that reduce their exposure to risk at the cost of lower profit rates the authors found that at high levels of rainfall variability differences in rates of profit per unit of agricultural assets were similar across classes of wealth but over the sample range of rainfall variability these rates of profit were always higher for the poorer farmers than for the wealthier ones suggesting that the disadvantages of small farmers in risk diffusion are more than offset by their labor cost advantage

network governance for competitiveness the role of policy networks in the economic performance of settlements in the izmir region some cities and regions grow faster than others and they increase their relative shares in the global economy the literature offers a wide list of factors of competitiveness most of which define individual capacities of cities recently however there has been an increasing focus on the importance of network governance and the policy networks formed between different cities this paper examines the importance of policy networks compared with other widely recognised factors of competitiveness to the economic performance of settlements in the izmir region and investigates the importance of classical competitiveness indicators and network relations on their economic performance with the use of econometric methods in conclusion it discusses the importance of policy networks in administrative reform processes and economic development policies

should african rural development strategies depend on smallholder farms an exploration of the inverse productivity hypothesis in africa most development strategies include efforts to improve the productivity of staple crops grown on smallholder farms an underlying premise is that small farms are productive in the african context and that smallholders do not forgo economies of scale a premise supported by the often observed phenomenon that staple cereal yields decline as the scale of production increases this paper explores a research design conundrum that encourages researchers who study the relationship between productivity and scale to use surveys with a narrow geographic reach when policy would be better served with studies based on wide and heterogeneous settings using a model of endogenous technology choice the authors explore the relationship between maize yields and scale using alternative data since rich descriptions of the decision environments that farmers face are needed to identify the applied technologies that generate the data improvements in the location specificity of the data should reduce the likelihood of identification errors and biased estimates however the analysis finds that the inverse productivity hypothesis holds up well across a broad platform of data despite obvious shortcomings with some components it also finds surprising consistency in the estimated scale elasticities

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

aggregate demand and interest rates a macroeconomic approach to the term structure this paper develops a model in which the term structure of interest rates obtains as an equilibrium outcome of the interactions of firms households and rationally informed speculators exogenous disturbances whose impact effects fall only in the market for short term bonds generate equilibrium movements in the yield on long term bonds and the level of investment spending in the case of risk averse speculators a purely transitory unanticipated shock to the money supply generates a long distributed lag effect on the level of aggregate demand

an optimizing analysis of the effects of world interest disturbances on the open economy term structure of interest rates abstract this paper studies the effects of world interest rate disturbances on the real domestic term structure of interest rates an intertemporal optimizing representative agent framework with variable employment and endogenous terms of trade is developed the economy faces an external borrowing constraint the adjustment of the short and long term rates as well as the discount bond yield curve is distinguished with the long rate and the yield curve derived recursively from the short both permanent and temporary world interest shocks are considered a notable result is that the yield curve exhibits relative maxima and minima for temporary disturbances

meso economic filters along the policy chain understanding the links between policy reforms and rural poverty in latin america abstract the paper clarifies the meso economy concept by defining it as comprising both the market mechanisms and administrative procedures through which policy decisions and market signals trickle down to the household level three main bodies of literature are reviewed the policy oriented literature in which the meso economy was initially considered the transaction cost approach analyzing market and policy failures and the micro economy level of agricultural household models the paper develops a synthesis of macro meso and micro economic perspectives which focuses on the roles played by three levels of filters intervening along the policy chain implications for policy and research are drawn

effects of demographic and related microeconomic change on land quality in hills and mountains of developing countries abstract more than 70 empirical studies indicate that local population growth and its microeconomic manifestations in hills and mountains of developing countries do not necessarily threaten forest production agriculture livestock production or watershed stability population growth can make the cost of land relative to labor increase as this cost increases people often change their methods of managing economic plants and animals and make land improvements to offset initial declines in productivity that result from more frequent use of land thus the relationship between land productivity and relative land labor costs often resembles a u halting population growth or removing people from well settled areas might not improve productivity or reduce some off site damages

migrant labor and farm technical efficiency in lesotho abstract the rural economy of lesotho is characterized by dependence on circular labor migration to south african mines and declining agricultural output per capita this paper attempts to improve the understanding of the relationship between circular labor migration and agricultural production by comparing the technical efficiency of farms that supply migrant laborers with that of farms that do not through analysis of the relative technical efficiency of these two farm categories conclusions are drawn concerning the likely impact of changing migration patterns on the agricultural sector

higher growth through the blue ocean strategy implications for economic policy a b s t r a c t higher growth is a key goal of companies governments and societies economic policies often attempt to attain this goal by targeting companies of certain sizes that operate in specific industries and focus on a specific business activity this approach to policy making has considerable shortcomings and seems to be less than fully effective in increasing economic growth we suggest a new approach to policy making that stems directly from the entrepreneurial perspective this approach examines a successful business strategy framework the blue ocean strategy to discover conditions for high growth we test the propositions on empirical data for two cases of successful high growth business namely slovenian gazelles and amazon com the results reveal a gap between the macro level of economic policy making to achieve higher growth and the micro level of business growth the findings call for a change in the focus of economic policies on specific size companies industries and business activities to intraindus try cooperation collaboration between companies of different sizes value innovation and creation of uncontested markets

impacts of migration on household production choices evidence from china abstractthe great migration from chinese farms to cities during the past several decades ranks among the most economically consequential of modern population movements we use a national sample of rice producing chinese households to examine the effects of that migration on agricultural production our assessment involves evaluating four alternative theories of labour market equilibrium in the framework of an expanded agricultural household model migration s farm production impacts appear to be slight not on account of farm labour market perfections or remittance financed technological improvements but by substituting a reduction in leisure and other low return activities for lost labour

impacts of climate policy on the competitiveness of canadian industry how big and how to mitigate competitiveness concerns have been at the forefront of climate policy debates in canada particularly as a result of its high energy intensity and significant exposure to international markets this paper uses a dynamic computable general equilibrium model to assess the likely impacts on sectoral competitiveness that would accompany efforts to meet greenhouse gas mitigation targets that have been set by the canadian government additionally it evaluates several design mechanisms that could be used to reduce the negative competiveness impacts associated with adoption of domestic climate policies the analysis suggests that several sectors would likely face significant competiveness challenges under a reference scenario in which permits are given to emitters in lump sum however it finds that competiveness impacts can be minimized by using output based recycling of permits or by using border tax adjustments

competitiveness and industrial policy from rationalities of failure towards the ability to evolve this article elaborates a dynamic rationale of industrial policy focusing on how to strengthen the socio economic system s ability to evolve i e how to achieve high real income together with qualitative change it highlights that the ubiquitous rationalities of failure be it of markets governments or systems are rooted in a peculiar habit of accepting hypothetical perfect states as normative benchmarks in contrast a dynamic logic of intervention should start from the question what the system aims to accomplish combining the structuralist ontology of micro meso and macro with the functional principles of evolutionary change the paper proposes a general typology of economic policies based on their respective contributions to the system s ability to evolve

the industrial policy of competitiveness a review of recent developments in the uk the article reviews the recent developments in uk competitiveness policy and explores its relationship with industrial policy including regional industrial policy it argues that competitiveness is virtually synonymous with productivity growth but that while four competitiveness white papers of the 1990s potentially broadened the scope of uk industrial policy the shift from sectoral to horizontal measures has in fact helped much reduce the content of this policy the article reviews current industrial policy and expenditure distinguishing between the areas of science and technology small firms and regional policy it argues that industrial policy is now a part of competitiveness policy being closely aligned to the efficiency role of government it finds that while policy has converged on a narrower set of measures the traditional boundaries between the science and technology small firm and regional policy components have become much less clear cut

embryonic knowledge based clusters and cities the case of biotechnology in scotland the cluster concept has been promoted in recent years as a panacea for economic development both locally and nationally one source of theoretical and empirical ambiguity in the concept is related to the spatial processes underpinning cluster development and to the relationship between cities and clusters in particular this paper examines the case of the biotechnology cluster in scottish cities with particular reference to glasgow and edinburgh the promotion of a biotechnology cluster has become a priority for scotland s economic development strategy because of its potential role in the knowledge driven economy the paper examines the major locational dynamics affecting biotechnology in scotland and interrogates the balance between the major forces driving the development of biotechnology firms in their urban location it concludes that the importance of cities to cluster growth lies mainly in the size and diversity of their labour markets in the presence of key research institutions and public sect

institutional reform and labor reallocation during transition theory evidence from polish agriculture abstract reallocation of agricultural labor during transition differs widely between regions and countries our analysis shows that agricultural labor reallocation in poland is determined by a the dramatic adjustment of prices and production costs caused by price liberalization and subsidy cuts b regional differences in farm organization and the impact of institutional reforms on these organizations c structural problems constraining intersectoral mobility the latter limit the benefits from the institutional reforms long term efficiency gains and sustainable rural development are conditional upon reducing such structural constraints and improving the functioning of the labor market

noncooperative decision making in the household evidence from malawi this paper proposes a novel test of productive efficiency in the household that also allows a test of noncooperative decision making i extend the collective model chiappori 1988 1997 to allow labor choices to affect future bargaining power by raising the value of outside options even if household consumption sharing is efficient labor choices are no longer efficient using data on malawi where there is predetermined variation in land rights that determine outside options in marriage i show that individuals spend more time on agricultural labor and less time on wage labor when household land is theirs they also have lower overall income and consumption the results are inconsistent with the fully efficient collective model but consistent with a noncooperative model with limited commitment where individuals allocate their labor supply to maximize future bargaining power limited commitment can lead to inefficient allocations that reduce household welfare

do changes in debt maturity composition affect the term structure some canadian evidence this paper examines the time series behaviour of the term structure of interest rates in the government of canada bond market to determine whether changes in the maturity composition of canada debt have had a significant effect on bond yields methodologically a reduced form model is estimated which incorporates exogenous information about both the level of domestic interest rates and the shape of the us term structure the empirical results indicate that the null hypothesis of no debt management effects in the government of canada bond market is rejected for monthly data

rural market imperfections and the farm size productivity relationship evidence from pakistan the subject of this article is the relationships between farm size and productivity and between farm size and profitability in the developing countries the recent controversies over the inverse size output relationship are reviewed and a framework is provided that explains the inverse relationship based on plausible assumptions about imperfections in the markets for labor land credit and risk from this framework a set of testable hypotheses are derived the hypotheses are tested on recent farm level panel data from pakistan a strong inverse relationship between farm size and yield is present in the sample even when household fixed effects are used to account for unobserved heterogeneity moreover the suggested market imperfections framework is consistent with the data

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
