controls on capital inflows and the transmission of external shocks in this paper we attempt to analyse whether price based controls on capital inflows are successful in insulating economies against external shocks we present results from vector autoregressive var models which indicate that chile and colombia countries that adopted controls on capital inflows seem to have been relatively well insulated against certain types of external disturbances subsequently we use the autoregressive distributive lag ardl approach to co integration in order to isolate the effects of the capital controls on the pass through of external disturbances to domestic interest rates in those economies we conclude that there is evidence that the capital controls have allowed for greater policy autonomy

the expansion of modern agriculture and global biodiversity decline an integrated assessment the world is banking on a major increase in food production if the dietary needs and food preferences of an increasing and increasingly rich population are to be met this requires the further expansion of modern agriculture but modern agriculture rests on a small number of highly productive crops and its expansion has led to a significant loss of global biodiversity ecologists have shown that biodiversity loss results in lower plant productivity while agricultural economists have linked biodiversity loss on farms with increasing variability of crop yields and sometimes lower mean yields in this paper we consider the macro economic consequences of the continued expansion of particular forms of intensive modern agriculture with a focus on how the loss of biodiversity affects food production we employ a quantitative structurally estimated model of the global economy which jointly determines economic growth population and food demand agricultural innovations and land conversion we show that even small effects of agricultural expansion on productivity via biodiversity loss might be sufficient to warrant a moratorium on further land conversion

profits and politics coordinating technology adoption in agriculture abstract this paper examines the political economy of government led coordination of economic activity in a simple two sector model in which individuals choice of agricultural technology affects industrialization we demonstrate the existence of multiple equilibria the economy is either characterized by the use of a traditional agricultural technology and a low level of industrialization or the use of a mechanized technology and a high level of industrialization relative to the traditional technology use of the mechanized technology increases output but leaves some population groups worse off we show that the distributional implications of choosing the mechanized technology restrict the possibility of pareto improving coordination by an elected policy maker even when we allow for income redistribution

induced innovation in american agiculture a reconsideration this paper investigates the role of induced innovation in the development of american agriculture from 1880 to 1980 the induced innovation hypothesis most closely associated with the work of hayami and ruttan argues that successful economies develop technologies in accordance with market price signals to loosen constraints on growth imposed by factor scarcities our analysis employing new state and regional level data fails to find support for hayami and ruttan s hypothesis this paper suggests that many of the fundamental generalizations about american agricultural development need to be reconsidered and redirects attention to the role of settlement changing crop patterns and biological investments in explaining changes in factor utilization in american agriculture

evolution of population resource dynamics models abstract this paper provides a comprehensive analysis of brander and taylor s 1998 model and its descendants from the following perspectives population growth substitutability innovation capital accumulation property rights and institutional designs and modeling approach this survey aims to contribute to a better understanding of population and resource dynamics models in general and facilitate further application of the model framework to relevant circumstances although often treated as exogenous in optimal growth models making population growth an endogenous function allows us to analyze broader effects of economic activities on population the issues of substitutability innovation and capital accumulation are intertwined allowing a model to address the effect of an endogenous technological change on substitutability between natural and man made capital facilitates our analyses of sustainability issues to address internalizing inter generational externalities in resource use incorporating property right changes and institutional designs to this type of model is a useful exercise but careful attention is needed for the consistency between such an arrangement and the mathematical representation of the depicted economy finally although the common criticism regarding convenient mathematical assumptions applies to the existing bt type models the use of computer simulation can relax such assumptions to better represent the intended relationships between the relevant variables

green revolution land reform and household income distribution in the philippines income of agricultural households consists of returns to labor capital and land from farming supplemented mainly by labor earnings from nonfarm sources agricultural technology affects farmers income through its effect on factor demands and factor prices which in turn induce changes in the allocation of farmers own resources to different uses income from farming is also affected by village institutions such as land tenure which governs the distribution of income between landlords and tenants as well as resource allocations

an error correction model of induced innovation in uk agriculture cointegration techniques are applied to a model of induced innovation based on the two stage constant elasticity of substitution ces production function this approach results in direct tests of the inducement hypothesis which are applied to agricultural data for the united kingdom from 1953 to 2000 the time series properties of the variables are checked cointegration is established and an error correction model ecm constructed which attempts to separate factor substitution from technological change finally the ecm formulation is subjected to causality tests which show that the factor price ratio for chemicals and land is granger prior to the factor saving bias of technological change however long run relative prices are not causally prior to the machinery labour ratio this results from perturbations in the user cost of machinery caused by oil price shocks thus the induced innovation hypothesis iih may explain long run transformations like the mechanical and fertilizer revolutions that

induced innovations and farm mechanization cal change in agriculture then they come mainly from the public agent of farm technology the agricultural research system the research system should be held responsible for the social consequences of farm mechanization and it should be budgeted and directed accordingly on the other hand if mechanization and exit from farming are caused mostly by external price and wage changes the responsibility of the research system is limited principally to technology improvement in this note we discuss the newly emerging tradition of induced innovation and its relation to the alternative explanations of machine labor substitution in agriculture we first clarify the conceptual basis of the induced innovation hypothesis and the related innovation possibility function second we call into question the validity of some of the empirical applications we argue that an incomplete conceptualization of the induced innovation idea has led to invalid empirical tests and to inappropriate implications on the causes of american farm mechanization

supply response and the dispersion of price expectations nomic an0lysis is the implication of aggregation when doing market studies the conditions for exact aggregation under a variety of definitions and settings have been studied paris and rausser theil the focus of this paper is on supply response in agriculture several authors have studied the effects of and tests for differential supply response coefficients across individuals or areas when aggregating firms e g theil p 567 here these coefficients are assumed to be identical for every firm but another problem is examined when uncertainty is present it is well documented that farmers have diverse price expectations e g bessler the question occurs as to the effects of such different expectations on aggregate supply response it is found that the curvature of the supply function is a crucial component of the analysis for example if the supply function is strictly concave an increase in the dispersion of expectations will reduce supply in aggregate

the induced innovation hypothesis and u s public agricultural research applicability of the induced innovation hypothesis that a change in relative input prices induces innovation to economize use of the increasingly expensive input hicks 1932 is examined for u s public agricultural research a reduced form test is developed using input prices from the agricultural production sector expenditures from the public research sector aimed at developing new technology to save specific agricultural inputs and variables to control for innovation marginal cost differences and nonhomotheticity unlike recent demand side studies that soundly reject the induced innovation hypothesis for agriculture support for the hypothesis is found for several input pairings through these tests of public agricultural research using state level panel data

growth and distribution a test of the induced innovation hypothesis for the korean economy this study investigates technical change biases and their effects on distribute shars in korea we are particularly concerned with whether technical change biases have been induced by changes in relative factor prices accompanied by rapid economic growth in korea our test results show that technical change in korea has been biased in the direction in the direction for saving labour and using capital thus rendering support to the induced innovation hypothesis these findings are roughly in parallel with empirical studies on the induced innovation hypothesis for the us and japanese economies the similar pattern in technical change biases between korea and the two advanced economies is noteworthy in light of their basic differences in factor endowments another salient feature of our empirical analysis is that the price corrected labour share in korea has continually shrunk in the process of rapid economic growth which has been partly precipitated by factor price disorting policies

market based systems for reducing chemical use in agriculture in the united states this study uses a computable general equilibrium cge model of the u s economy to estimate the economic effects of agricultural fertilizer and pesticide input reductions on individual farm sectors and on the economy as a whole the costs of reducing agricultural chemicals using a market based approach and a command and control approach are compared the real cost to society of restrictng fertilizer and pesticide use by 20 percent across all uses is estimated to be 2 3 billion a market based approach that would provide incentives to reduce chemical use in the most cost efficient manner would be about 10 percent less costly

estimating labor supply and production decisions of self employed farm producers abstract this paper proposes a model oriented towards integrating farm households production and consumption decisions into a unified theoretical and econometric framework it is argued that in contrast with other forms of economic organization farm households utility and profit maximization decisions are not likely to be independent econometric estimation of a farm household model using canadian data suggests that utility and profit maximizing decisions are not indeed independent and moreover that there are significant gains in explanatory power and efficiency by estimating the consumption and production equations jointly

the relevance of p star analysis to uk monetary policy recent articles have attempted to restore the use of a simple measure of the money supply as an indicator of future price levels p star and to reestablish a causal link from money to prices in this paper we argue that the p star approach is flawed it is certainly more complex than traditional monetarist approaches but the fundamental questions of causality are in no way either affected or resolved we argue that the p star relationship does not have a causal link with prices but rather the causality runs from prices to money we also find that there is some causality running from money to real income so that monetary conditions do seem to have some predictive power for future levels of activity copyright 1994 by royal economic society

technology adoption and agricultural price policy market interventions such as price supports or fertilizer subsidies can lead to gains from speeding up adoption of new technologies but the policies distort resource allocation a framework is developed for optimizing policies in light of the adoption allocation trade off based on adoption coefficients and production parameters from third world agriculture levels and duration of policies are estimated sensitivity analyses are performed gains are small at best and may be zero or negative in view of farmer costs of adjustment and deadweight losses from taxes profit technology adoption if new technologies are desirable why not use price supports or input subsidies to encourage faster technology adoption while frequently raised in policy deliberations this question has received little serious analysis particularly neglected has been the conflict or trade off between a gains in output as producers switch from old to new technologies and b the losses from resource use distortions brought about by price policies when output prices are raised or prices of inputs such as fertilizer are lowered the

supply and demand functions for multiproduct u s cash grain farms biases caused by research and other policies this study presents new estimates of supply and demand elasticities for u s multiproduct cash grain farms and estimates of input and output bias effects caused by public and private crop research extension and farmers schooling the study also shows that the social rate of return to public crop research is large about 62 percent

labor productivity measurement in japanese agriculture 1956 1990 abstract this paper investigates the factors responsible for a drastic decline in the growth rate of labor productivity of the agricultural sector for the 1956 1990 period this investigation is carried out by a newly devised procedure which decomposes the growth rate of labor productivity into 1 the total substitution effect which consists of the effects due to factor price changes and biased technological change and 2 the tfp effect composed of the effects due to scale economies and technological progress based on empirical estimation of the translog cost function it was found that the total substitution effect contributed to the growth of labor productivity much more than the tfp effect did for the period under question

how effective are capital controls a number of authors have recently argued that in order to avoid financial instability emerging countries should rely on capital controls two type of controls have been considered controls on capital outflows and controls on capital inflows in this paper i review the historical evidence on the effectiveness of these two type of controls i argue that controls on outflows have been ineffective they are circumvented and breed corruption i also analyze chile s recent experience with controls on inflows and i argue that their effectiveness has been exaggerated

a flexible model of factor biased technological change an application to japanese agriculture abstract results indicate that when restrictive assumptions on production structure and parameter constancy are avoided and quality adjusted flow variables employed an explanation of factor biased technological change emerges that is consistent with observed patterns of factor use while substitution possibilities during this period were limited biol nearly as strong a substitute for labor as for land technological change was found to be significantly labor saving and using in biological inputs and machinery and only weakly land saving descriptions of pre world war ii technology as primarily land saving miss the significant contribution of labor saving technology in agricultural transformation and ignore the dynamics of inter sectoral factor demand

global population growth technology and malthusian constraints a quantitative growth theoretic perspective we structurally estimate a two sector schumpeterian growth model with endogenous population and finite land reserves to study the long run evolution of global population technological progress and the demand for food the estimated model closely replicates trajectories for world population gdp sectoral productivity growth and crop land area from 1960 to 2010 projections from 2010 onwards show a slowdown of technological progress and because it is a key determinant of fertility costs significant population growth by 2100 global population reaches 12 4 billion and agricultural production doubles but the land constraint does not bind because of capital investment and technological progress

not your grandfather s imf global crisis productive incoherence and developmental policy space the response by the international monetary fund imf and developing country national governments to the current global financial crisis represents a moment of what i term productive incoherence which has displaced the constraining neoliberal coherence of the past several decades productive incoherence refers to the proliferation of inconsistent and even contradictory strategies and statements by the imf that to date have not congealed into any sort of new organised regime those who see continuity at the imf emphasise the reassertion of the imf s authority the reiteration of pro cyclical policy adjustment and the maintenance of existing governance patterns within the institution in contrast evidence of discontinuity includes a world now populated by increasingly autonomous states in the south the normalisation of capital controls and fund conditionality programmes that are inconsistent in key respects in the face of this evidence it is best to understand the current conjuncture as an interregnum that is pregnant with new development possibilities

geographic aggregation and induced innovation in american agriculture the induced innovation hypothesis is tested for the usa and western regions using cointegration procedures an error correction model separates short run and long run effects of relative price changes a significant difference in the elasticities of factor substitution along the isoquant and the innovation possibility curve implies induced innovation the estimated results support the hypothesis for washington the pacific northwest and the western region but not for the nation corroborative tests of weak exogeneity fail to support the hypothesis in any of the geographic units changes in output level and research investment do not significantly bias agricultural technology in the usa

research and extension expenditures and productivity in japanese agriculture 1960 1990 abstract this paper investigates the cause for the decline in the growth of productivity in japanese agriculture since the late 1960s for this objective it investigates the effects of research and extension r e activities on the extent and the direction of the bias of technological change in japanese agriculture for the period 1960 1990 based on the translog cost function framework empirical results show that the cost reducing effects of r e measured in terms of the absolute value of the cost r e elasticity increased slightly from 0 194 in 1960 to 0 205 in 1965 and then decreased consistently to 0 110 in 1990 this finding is broadly consistent with the finding of the decline or slowdown in agricultural productivity since the late 1960s the bias due to r e was found to be toward labor intermediate inputs and other inputs saving on the one hand and machinery and land using on the other labor saving and machinery using biases are consistent with the hicksian induced innovation hypothesis

agricultural productivity revisited this paper describes production accounts for agriculture output is defined as gross production leaving the farm as opposed to real value added inputs are not limited to capital and labor but include intermediate inputs as well we derive index numbers of gross output capital labor and intermediate inputs these data are used to construct indexes of total factor productivity we then compare the contributions of input growth and productivity growth to economic growth the important role of productivity growth in agriculture becomes immediately apparent

characteristics of the prices of operating reserves and regulation services in competitive electricity markets in this paper characteristics of the prices of reserves and regulation services in the ontario new york and ercot electricity markets are studied more specifically price variability price jumps long range correlation and non linearity of the prices are analyzed using the available measures in the literature for the ontario electricity market the prices of 10 min spinning 10 min non spinning and 30 min operating reserves for the period may 1 2002 to december 31 2007 are analyzed for the new york market prices of the same reserves plus regulation service are studied for the period february 5 2005 to december 31 2008 for the ercot market we analyze the prices of responsive reserve regulation up and regulation down services for the period january 1 2005 to december 31 2009 the studied characteristics of operating reserve and regulation prices are also compared with those of energy prices the findings of this paper show that the studied reserve and regulation prices feature extreme volatility more frequent jumps and spikes different peak price occurrence time and lower predictability compared to the energy prices

pricing energy and ancillary services in integrated market systems by an optimal power flow a detailed ac opf based formulation for procuring pricing and settling energy and ancillary service in simultaneous auctions by integrated market systems is presented the paper provides clear definitions of locational marginal prices for energy and ancillary service marginal prices in terms of lagrange multipliers the characteristics of the prices are analyzed especially when economic substitution among ancillary services is required the paper also evaluates the conditions under which opportunity costs are incurred to units that provide ancillary services it is particularly shown that the intuitive belief that the provision of regulation down service does not incur opportunity cost to the provider in general is not true

solvency rule and capital centralisation in a monetary union brancaccio and fontana 2013 have suggested that the central bank influences the solvency conditions of firms and households in the economic system this solvency rule is examined here within a stylised model of a monetary union characterised by different rates of accumulation and inflation across its two member countries the rule highlights the existence of a relationship between the interest rate set by the central monetary authority and the allocation of ownership of existing physical capital among the member countries of the monetary union i e the rates of capital centralisation the paper also shows the nexus between solvency and government debt sustainability and examines the implications of deflationary or currency devaluation policies for the solvency conditions

scheduling and pricing for expected ramp capability in real time power markets higher variable renewable generation penetrations are occurring throughout the world on different power systems these resources increase the variability and uncertainty on the system which must be accommodated by an increase in the flexibility of the system resources in order to maintain reliability many scheduling strategies have been discussed and introduced to ensure that this flexibility is available at multiple timescales to meet variability that is the expected changes in system conditions two recent strategies have been introduced time coupled multi period market clearing models and the incorporation of ramp capability constraints to appropriately evaluate these methods it is important to assess both efficiency and reliability but it is also important to assess the incentive structure to ensure that resources asked to perform in different ways have the proper incentives to follow these directions which is a step often ignored in simulation studies we find that there are advantages and disadvantages to both approaches we also find that look ahead horizon length in multi period market models can impact incentives this paper proposes scheduling and pricing methods that ensure expected ramps are met reliably efficiently and with associated prices based on true marginal costs that incentivize resources to do as directed by the market case studies show improvements of the new method

the great crash of 2008 and the reform of economics the 2008 economic crash led to remarkable shifts of opinion among world leaders does this crisis create favourable conditions for the reform and revitalisation of economics itself from a subject dominated by mathematical techniques to a discipline more oriented to understanding real world institutions and actors and why were warnings of financial collapse not heeded recent shortcomings are partly related to the global triumph of market individualist ideology and partly to the exaggerated roles of modelling and quantification these failures of economics are partly peculiar to the discipline and also a result of other wider institutional and cultural forces

welfare impacts of alternative public policies for agricultural pollution control in an open economy a general equilibrium framework a general equilibrium approach is used to evaluate the welfare impacts of alternative policies for reducing agricultural pollution in an open economy with preexisting distortions caused by income taxes and agricultural subsidies the policies examined here include the removal of distortionary agricultural subsidies we find that even though these distortions are small compared to others in the economy removing them and imposing nitrogen reduction subsidies and or output taxes can enhance welfare and reduce nitrogen pollution thereby leading to a substantial double dividend the relative efficiency of the alternative policies examined here depends on the level of the nitrogen reduction target copyright 2008 oxford university press

specification of production functions for analyzing technical change and factor inputs in agricultural development abstract this paper focuses on some vital issues involed in specifying the number of variables to be included in agriculture s production function and on the functional form that the agricultural production function should assume in the context of a computable general equilibrium model when land and intermediate inputs seeds and fertilizers as well as capital and labor are included modeling the agricultural sector can best be done in a more disaggregated format than simple cobb douglas or ces specifications after examining the transcendental logarithmic production function the paper proposes to adopt nested ces specifications on the basis of empirically observed elasticities of substitution

capital services in u s agriculture concepts comparisons and the treatment of interest rates this paper begins with a review of the methods and assumptions used to measure capital service flows two data series on capital inputs in u s agriculture are briefly described and compared we show that measures of capital services are sensitive to the treatment of interest rates notably the use of fixed versus variable market rates significantly affects measures of the quantity and productivity of agricultural capital in the united states we conclude that when calculating capital usage in u s agriculture the use of a fixed interest rate generates more plausible estimates than the use of an annual market rate

the structure of u s agricultural technology 1910 78 this paper utilizes 1910 78 time series data and a single product aggregate translog profit function to measure the structure of u s agricultural technology duality relations are used to devise a multifactor measure of biased technical change a measure of nonhomotheticity is introduced which indicates the effects scale change has had on aggregate cost shares the empirical analysis finds that different nonhomothetic technologies characterized the prewar and postwar periods differing technical change biases are consistent with relative price trends during the two periods showing that the long run structure of u s agricultural technology has been consistent with the hayami ruttan induced innovation theory

iceland s rise fall stabilisation and beyond iceland is an unusually pure example of the dynamics that blocked regulation and caused financial fragility across the developed world for 20 years this essay describes the statist and corporatist political economy of the country as it soared from near the bottom of the western european income hierarchy at the end of the world war ii to up near the top by the 1980s it illustrates how a group of neoliberal politicians and allied civil servants drove through selective deregulation and privatisation in the 1990s and 2000s in the space created for newly privatised banks icelandic financiers grew the banks and linked private equity firms through mergers and acquisitions abroad to the point where by 2007 tiny iceland supported three banks in the world s biggest 300 banks with assets eight times the gdp second highest in the world after switzerland as profits from these overseas operations were partly redistributed back to iceland the economy boomed in the grip of super minsky processes the government the banks and the media interpreted the boom as testimony to the validity of neoliberal policies and went out of their way to hide increasing financial fragility from view preventing a negative or self correcting policy feedback loop the accident waiting to happen happened in the wake of the lehman collapse in september 2008 the essay charts the zigzags of the government s response and the citizens response and discusses the prospects for a resumption of growth on a more sustainable basis it suggests that iceland illustrates in miniature the ratcheting down of mass living standards underway across the western world now that the cushion of debt has been removed even as financiers and others in the top few percentiles of national income distributions increase their share of national income but economic institutions and politics matter in iceland the large devaluation spread the cut in a relatively apolitical way the government let the banks go bust rather than bail them out at taxpayers expense it imposed capital controls on outflows and it used fiscal transfers to protect the bottom half of the population from disproportionate cuts

the evolving design of rto ancillary service markets abstract although the markets for ancillary services at the north american independent system operators are often structured in quite different ways there is an emerging set of core design elements that represent a rough consensus as to what the optimal design configuration for ancillary services should be albeit with some regional variation this paper looks back at how the design of ancillary services markets has recently evolved to put this development in context thereafter it examines the methods by which ancillary services are procured by highlighting the procurement practices at a number of different independent system operators principally those in california new york new england texas and the pjm interconnection in an attempt to tease out the remaining reasons why the ancillary service markets are still so different this is important as there are many innovations that are not rooted in regional differences but reflect genuine technical advances and economic efficiency gains and can be replicated across other isos to produce more efficient designs greater reliability and lower costs

testing the induced innovation hypothesis an error correction model of south african agriculture abstract this paper applies cointegration techniques to a model of induced innovation based on the two stage constant elasticity of substitution ces production function this approach results in direct tests of the inducement hypothesis which are applied to data for south african commercial agriculture for the period 1947 1991 south african data is used because the policy changes have been substantial enough that the factor and price ratios have turning points rather than being monotonic the time series properties of the variables are checked cointegration is established and an error correction model ecm constructed allowing factor substitution to be separated from technological change finally the ecm formulation is subjected to causality tests which show that both the factor price ratios and r d and extension expenditures are granger prior to the factor saving biases of technological change thus each stage of the analysis corroborates the inducement hypothesis however straightforward price inducement is only part of the explanation of changes in factor ratios policy induced innovation in response to tax concessions and subsidised credit is also present

managing capital accounts in emerging markets lessons from the global financial crisis abstract the global financial crisis forcefully highlighted the importance of curbing the impact of large and volatile capital inflows on growth and financial stability in developing countries it led the imf to reconsider its long standing rejection of capital controls yet its new macroeconomic policy first approach has to be reconciled with the hybrid nature of banking activity and its role in transmitting global shocks a consideration of dominant actors and strategies of intermediating capital inflows offers distinct policy options ranging from carefully designed central bank strategies to institutional changes that realign bank incentives towards longer horizons and sustainable growth models

global economic growth and agricultural land conversion under uncertain productivity improvements in agriculture we study how stochasticity in the evolution of agricultural productivity interacts with economic and population growth at the global level we use a two sector schumpeterian model of growth in which a manufacturing sector produces the traditional consumption good and an agricultural sector produces food to sustain contemporaneous population agriculture demands land as an input itself treated as a scarce form of capital in our model both population and sectoral technological progress are endogenously determined and key technological parameters of the model are structurally estimated using 1960 2010 data on world gdp population cropland and technological progress introducing random shocks to the evolution of total factor productivity in agriculture we show that uncertainty optimally requires more land to be converted into agricultural use as a hedge against production shortages and that it significantly affects both optimal consumption and population trajectories

biased technological change and factor demand in postwar japanese agriculture 1958 84 abstract the objective of this study is to gain a better understanding of factor substitutions in postwar japanese agriculture by shedding special light on biased technological change such biased technological change is first measured then associated with the movements of factor prices and then tested for the hicksian induced innovation hypothesis in addition a decomposition analysis is carried out in order to quantitatively examine the importance of the biased effects for determining changes in factor cost shares and factor proportions during the 1958 84 period a slightly modified stevenson greene model of the translog cost function is employed this model has at least two important advantages over ordinary translog cost functions first it incorporates time into the model such that all coefficients of the ordinary translog cost function may change over time this is more realistic than the ordinary translog cost function which assumes that all coefficients are constant over the period of estimation another attractive feature is that it enables us to test the induced innovation hypothesis directly the model is applied to the 1958 84 period by making use of farm level data the results show that technological change was biased towards saving labor and other inputs and using machinery intermediate inputs and land this biased technological change is found to be in principle consistent with the induced innovation hypothesis furthermore it is shown through decomposition analyses that the biased technological change had significant impacts on changes in factor cost shares and factor proportions during these years the empirical results of this study imply that technological change in japanese agriculture has in general proceeded in a manner consistent with factor endowments conditions since the late 1950s an implication of this study for agriculture in less developed countries is that agricultural policies seeking development through technological progress should be carried out so as to take advantage of peculiar factor endowments conditions in the individual countries

induced bias of technical change in agriculture the united states and japan 1880 1980 because of extreme differences in factor endowments and price ratios among factors between the united states and japan both countries have experienced sharply different patterns of factor use and productivity growth in agriculture for the past 100 years of modern economic growth in this study the method of testing the hicksian hypothesis of induced innovation was developed using the two level ces production function the model was applied to the historical data of u s and japanese agricultural development for 1880 1980 the results were consistent with the hypothesis that different patterns of technical change in the two countries were induced by differences in the levels and the movements in relative factor prices

induced innovation and marginal cost of new technology abstract lacking data on development and implementation costs for input saving technologies we develop a nonparametric procedure to estimate relative differences in marginal technology costs for technical change to be consistent with the induced innovation hypothesis we apply it to u s agriculture

induced innovation in u s agriculture time series direct econometric and nonparametric tests the hypothesis of induced innovation is tested for u s agriculture using a high quality state level panel data set and three disparate testing techniques time series direct econometric and nonparametric we find little support for the hypothesis that conclusion is robust across testing techniques however as with all empirical tests of this hypothesis conducted to date ours focus only on the demand side of the hypothesis the hypothesis could have been rejected simply because the marginal cost of developing and implementing input saving technologies for the relatively expensive inputs is greater than for the relatively cheap inputs copyright 2009 oxford university press
