banking in computable general equilibrium economies abstract in this paper we develop a computable general equilibrium economy that models the banking sector explicitly banks intermediate between households and between the household sector and the government sector households borrow from banks to finance their purchases of houses and they lend to banks to save for retirement banks pool households savings and they purchase interest bearing government debt and non interest bearing reserves we use this structure to answer two sets of questions one normative in nature that evaluates the welfare costs of alternative monetary and tax policies and one positive in nature that studies the real effects of following a procyclical interest rate policy rule

does it matter how monetary policy is implemented abstract in the u s existing monetary base measures add an adjustment factor for changes in reserve requirement ratios to high powered money implicitly the monetary base assumes that the economic effects of changes in reserve requirements are identical to those due to changes in high powered money theory however does not generally support the prediction that the two policy tools will have the same economic effects structural vars are estimated to compare the short run paths of inflation and output growth under two different types of policy shocks in doing so this analysis gives one a measure of the costs associated with this implicit equivalence assumption the evidence is consistent with the hypothesis that the federal reserve at least partially offsets reserve requirement changes with open market operations and the hypothesis that dynamic explanations of macroeconomic variables are improved by separating reserve requirement changes from other monetary policy moves

the inflation tax in a real business cycle model money is incorporated into a real business cycle model using a cash in advance constraint the model economy is used to analyze whether the business cycle is different in high inflation and low inflation economies and to analyze the impact of variability in the growth rate of money in addition the welfare cost of the inflation tax is measured and the steady state properties of high and low inflation economies are compared

trade credit in a monetary economy abstract this paper examines the importance of financial and technological stochastic trends in the context of a stochastic dynamic general equilibrium monetary economy with multiple means of payment in contrast to earlier empirical work we find support for both a long run substitution condition between money trade credit and interest rates as well as a long run transactions demand for alternative payments media consistent with real business cycle frameworks

the federal funds rate and the channels of monetary transmission the authors show that the interest rate on federal funds is extremely informative about future movements of real macroeconomic variables then they argue that the reason for this forecasting success is that the funds rate sensitively records shocks to the supply of bank reserves that is the funds rate is a good indicator of monetary policy actions finally using innovations to the funds rate as a measure of changes in policy the authors present evidence consistent with the view that monetary policy works at least in part through credit i e bank loans as well as through money i e bank deposits copyright 1992 by american economic association

revisiting the role of education for agricultural productivity while the majority of micro studies finds that rural education increases agricultural productivity various recent cross country regressions analysing the determinants of agricultural productivity were only able to detect insignificant or even surprising negative effects of schooling in this paper we argue and show that this failure to find a positive impact of education in the international context is rather a data problem related to the use of enrolment and literacy indicators using a panel of 95 developing and middle income countries from 1961 to 2002 together with the newest version of the barro lee educational attainment dataset we show that education indeed has a highly significant positive effect on agricultural productivity which is robust to changes in the control variables and in the econometric methods applied distinguishing between different levels of education further reveals that only primary and secondary schooling have significant positive impacts while tertiary education remains insignificant finally the effect of education is estimated separately for countries with different income levels results indicate that the coefficient of the education variable remains insignificant for countries from the poorest three income quintiles while it is positive and highly significant for the richest two quintiles this finding can be interpreted as support for the prominent argument claiming that education leads to higher agricultural productivity only in the presence of rapid technical change where education will help farmers to adjust more readily to the new opportunities

liquidity effects and the monetary transmission mechanism several recent papers provide strong empirical support for the view that an expansionary monetary policy disturbance generates a persistent decrease in interest rates and a persistent increase in output and employment existing quantitative general equilibrium models which allow for capital accumulation are inconsistent with this view there does exist a recently developed class of general equilibrium models which can rationalize the contemporaneous response of interest rates output and employment to a money supply shock however a key shortcoming of these models is that they cannot rationalize persistent liquidity effects this paper discusses the basic frictions and mechanisms underlying this new class of models and investigates one avenue for generating persistence we argue that once a simplified version of the model in christiano and eichenbaum 1991 is modified to allow for extremely small costs of adjusting sectoral flow of funds positive money shocks generate long lasting quantitatively significant liquidity effects as well as persistent increases in aggregate economic activity

money output and income velocity this paper attempts to assess empirically the contribution of three structural shocks monetary institutional financial and fiscal and technological to output and velocity fluctuations in the national bank era and the post 1973 period to identify these shocks we impose only long run restrictions derived from a monetary growth model we find that higher money growth increases decreases velocity in the first second period depending crucially on the resulting changes in the transactions frequency credit enhancing financial or expansionary fiscal shocks have a permanent positive effect on velocity and a himp shaped effect on output whereas technological shocks cause velocity to decrease in the short run and output to move to a permanently higher level

linking risk aversion time preference and fertilizer use in burkina faso this paper investigates whether burkinabe maize farmers fertilizer use decisionsare correlated with their risk and time preferences we conducted a survey and a se ries of hypothetical experiments on a sample of 1 500 farmers we find that morepatient farmers do use more fertilizer but it is only because they plant more maize afertilizer intensive crop rather than because they use more fertilizer per hectare ofmaize planted conversely we find no statistically significant link between risk aver sion and fertilizer use we use a simple two period model which suggests that riskaversion may indeed have an ambiguous effect on fertilizer use

the roles of risk and ambiguity in technology adoption we study the impacts of risk and ambiguity aversion on the adoption of new technologies specifically genetically modified gm corn and soy seeds we conduct experiments measuring risk and ambiguity aversion with midwestern grain farmers risk aversion has only a small impact on the timing of adoption of gm soy while ambiguity aversion has a large impact speeding up farmer adoption of gm corn we hypothesize that this unusual finding is due to the fact that gm corn often contains an insect resistance trait which reduces the ambiguity of pest damages for adopters gm soy never contains this insect resistance trait this highlights the importance of distinguishing between risk and ambiguity when studying the effects of aversion to uncertainty on adoption of new technologies

parametric analysis of setup cost in the economic lot sizing model without speculative motives in this paper we consider the important special case of the economic lot sizing problem in which there are no speculative motives to hold inventory we analyze the effects of varying all setup costs by the same amount this is equivalent to studying the set of optimal production periods when the number of such periods changes we show that this optimal set changes in a very structured way this fact is interesting in itself and can be used to develop faster algorithms for such problems as the computation of the stability region and the determination of all efficient solutions of a lot sizing problem furthermore we generalize two related convexity results which have appeared in the literature

monetary information and monetary neutrality abstract the monetary theory of business fluctuations in market clearing models constructed under the rational expectations assumption as advanced by lucas and others involves the idea that suppliers and demanders will typically misinterpret movements in the general level of prices as representing more or less favorable relative opportunities for real activities the present paper examines the consequences of agents possessing contemporaneous monetary information of a potentially noisy variety for the non neutrality of unanticipated monetary events within such an equilibrium business cycle model this modification of the information structure has the strong testable implication that real activity will be uncorrelated with contemporaneous monetary data

international portfolio nondiversification and exchange rate variability abstract incomplete international portfolio diversification is implied by an equilibrium models of exchange rates with nontraded goods the model can also explain the greater correlation between consumption and income within a country than between consumption across countries nontraded goods make more stringent the elasticity conditions required to explain exchange rate variability resulting from current productivity disturbances though not from disturbances to fiscal policies or the prospective return to investment the model is also consistent with international real interest rate differentials changes over time in the current account and relative wealth across nations and observed time series properties of exchange rates

risk aversion and credit constraints in farmers decision making a reinterpretation in 1976 the agricultural development council sponsored a conference on risk uncertainty and agricultural development which has been summarised in a volume edited by james roumasset jean marc boussard and inderjit singh 1979 the volume provides an excellent review of the state of the art at that time however as discussed in the summary chapters of that volume there were few theoretical empirical or policy issues on which clear conclusions could be reached on the basis of knowledge then available in the intervening years progress has been made on a number of issues as a result of both empirical investigations and theoretical advances this paper concentrates on advances which have relevance to the controversy about the relative roles of risk aversion and credit constraints in limiting farmers investment levels especially for purchased inputs such as seeds or fertilizers in particular we review recent experimental studies on the extent of risk aversion among farmer populations in developing

money and disaggregate supply in the united states 1950 1982 the impact of money growth and money growth surprises on real output by sector is investigated it is shown that money provides a significant contribution to the explanation of the real output cycles in almost all sectors of the u s economy anticipated money is found to have real effects though there is some evidence that the real impact of money surprises is larger

nominal price rigidity money supply endogeneity and business cycles abstract this paper investigates the ability of nominal price rigidity to explain the co movement of inflation with the cyclical component of output observed in the post war u s data a dynamic general equilibrium model is constructed with the introduction of monopolistic competition and nominal price rigidity in a standard real business cycle model allowing for an endogenous money supply rule it is then demonstrated that sticky price models can explain the observed associations between movements in inflation and output much better than flexible price models this result depends little on whether money supply is assumed to be endogenous or not

liquidity effects monetary policy and the business cycle this paper presents a flexible price quantitative general equilibrium model with the property that a positive money supply shock drives the nominal interest rate down and aggregate employment output and the real wage up these implications are broadly consistent with postwar u s data the two key features of the model that are responsible for its properties are 1 money shocks have a heterogeneous impact on agents and 2 ex post inflexibilities in production give rise to a very low short run interest elasticity of money demand in our model the extent of the drop in the interest rate after a positive money supply shock depends on the degree to which production is ex post inflexible given sufficient ex post inflexibility the model conforms well with the view widely held within the u s federal system that the short run interest rate elasticity for total reserves is very close to zero copyright 1995 by ohio state university press

the causes of bank failures deflationary spells abstract unexpected reductions in inflation induce debtor insolvency and bank failures with lags of up to eight years outside money is non neutral because the default of marginal banks and the rising costs of surviving banks reduce the supply of monetary services

oil and the macroeconomy since world war ii all but one of the u s recessions since world war ii have been preceded typically with a lag of around three fourths of a year by a dramatic increase in the price of crude petroleum this does not mean that oil shocks caused these recessions evidence is presented however that even over the period 1948 72 this correlation is statistically significant and nonspurious supporting the proposition that oil shocks were a contributing factor in at least some of the u s recessions prior to 1972 by extension energy price increases may account for much of post opec macroeconomic performance

a banking explanation of the us velocity of money 1919 2004 the paper shows that us gdp velocity of m1 money has exhibited long cycles around a 1 25 per year upward trend during the 1919 2004 period it explains the velocity cycles through shocks constructed from a dsge model and annual time series data ingram et al 1994 model velocity is stable along the balanced growth path which features endogenous growth and decentralized banking hat produces exchange credit positive shocks to credit productivity and money supply increase velocity as money demand falls while positive goods productivity shock raises temporary output and velocity the paper explains such velocity volatility at both business cycle and long run frequencies with filtered velocity turning negative starting during the 1930s and the 1987 crashes and again around 2003 results suggest that the money and credit shocks appear to be more important for velocity during less stable times and the goods productivity shock more important during stable times

monetary aggregates and the business cycle a monetary aggregate consisting predominantly of zero maturity deposits called mzm tends to systematically lead output in the us business cycle such fluctuations are observed both before and after the 1979 monetary policy change similar dynamics are obtained in a model with multi stage production and purchase size heterogeneity when agents optimally choose their mix of cash checkable and time deposits used in transactions the causality in the model runs from real activity to money rather than the other way around although the monetary base is endogenous through a taylor type rule the lead in mzm is primarily driven by deposit creation

expectations and monetary neutrality an empirical reexamination modern monetary business cycle models feature rational expectations and natural rate assumptions which imply that unanticipated changes in nominal aggregates affect real output but anticipated changes do not initial tests conducted by barro 3 and by barro and rush 4 supported the neutrality of anticipated money growth in a particularly influential study mishkin 21 22 rejected the neutrality of anticipated policy mishkin s paper 21 has become one of the most frequently cited studies in empirical macroeconomics the influence of the study probably derives in large part from the unequivocal nature of the results in particular mishkin showed that i the hypothesis that anticipated policy has no effect on output is strongly rejected ii anticipated nominal changes have a greater estimated effect on output than do unanticipated nominal changes iii lags as long as 17 quarters have significant coefficients implying that barro s eight lag model was underspecified iv in some specifications the estimated sign of the effect of nominal innovations is opposite to the prediction of monetary business cycle theory frydman and rappoport 9 used mishkin s empirical model to provide further evidence against the neutrality hypothesis by showing that the data provide no evidence for distinguishing between the output effects of anticipated policy and those of unanticipated policy although several subsequent studies have supported the neutrality hypothesis 7 12 mishkin s careful study and a small number of additional studies suggest that the neutrality hypothesis is not robust the empirical rejection of the neutrality hypothesis contradicts a wide range of modern monetary models including those based on imperfect information 14 18 19 and those based on imperfect competition 8 20 as a consequence the focus of macroeconomists has in recent years shifted to non monetary models in which money responds passively to changes in aggregate output 16 17 this paper explores the robustness of mishkin s results using an updated data set the model yields results that are more consistent with the neutrality hypothesis than those of mishkin in par

farm productivity and efficiency in rural bangladesh the role of education revisited this article reassesses the debate over the role of education in farm production in bangladesh using a large dataset on rice producing households from 141 villages average and stochastic production frontier functions are estimated to ascertain the effect of education on productivity and efficiency a full set of proxies for farm education stock variables are incorporated to investigate the internal as well as external returns to education the external effect is investigated in the context of rural neighbourhoods our analysis reveals that in addition to raising rice productivity and boosting potential output household education significantly reduces production inefficiencies however we are unable to find any evidence of the externality benefit of schooling neighbour s education does not matter in farm production we discuss the implication of these findings for rural education programmes in bangladesh

sectoral shifts and cyclical unemployment a substantial fraction of cyclical unemployment is better characterized as fluctuations of the frictional or natural rate than as deviations from some relatively stable natural rate shifts of employment demand between sectors of the economy necessitate continuous labor reallocation since it takes time for workers to find new jobs some unemployment is unavoidable this paper presents evidence that most of the unemployment fluctuations of the seventies unlike those in the sixties were induced by unusual structural shifts within the u s economy simple time series models of layoffs and unemployment are constructed that include a measure of structural shifts within the labor market these models are estimated and a derived natural rate series is constructed

supply shocks and the interest rate supply shocks and the interest rate i introduction a new approach to business cycles that stresses intertemporal substitution possibilities and market clearing equilibria has recently gained prominence key models that use this new classical framework include those of lucas 1972 barro 1976 1981b 1987a 1987g kydland and prescott 1980 1982 long and plosser 1983 and king and plosser 1984 although these models share the basic similarity of intertemporal maximization and market clearing they differ about which factors cause business cycle fluctuations however most of them admit a role for supply shocks such as opec oil price shocks and agricultural harvest failures most of the empirical work using the market clearing approach concentrates on quantities such as real gnp and ignores the key price variable of the intertemporal substitutional approach the real interest rate exceptions are the papers by benjamin and kochin 1984 and barro 1987a who use eighteenth and nineteenth century data to examine the effect of government spending on the nominal interest rate this paper extends previous work by studying not only the effects of government spending on the interest rate but also the effects of supply shocks on the interest rate the classic supply shock agricultural harvests is used indeed to the best of our knowledge this is the first paper to investigate how agricultural supply shocks affect the interest rate and as such it provides additional evidence about the factors that influence interest rates although the theory behind this work is cast in the framework of the equilibrium approach keynesian models also concur with the theoretical prediction that supply shocks raise the real interest rate thus this empirical investigation of the impact of harvests on the interest rate will command attention from keynesian as well as new classical macroeconomists section ii reviewers the theory used to motivate the work the third section discusses the data the fourth section presents the empirical results while the last section contains conclusions ii theory the equilibrium approach to macroeconomics emphasizes the role played by intertemporal optimization consumers maximize their intertemporal utility functions while firms maximize their profits as a result an intertemporal relative price the ex ante real interest rate emerges as a crucial variable consider the effect on the ex ante real interest rate from a temporary adverse supply shock such as a harvest failure in an agricultural closed economy consumers faced with a temporary shortfall in income and trying to smooth their consumption generally try to borrow in order to maintain their usual level of consumption thus the ex ante real interest rate increases much the same argument applies to government spending a temporary increase in government spending reduces the resources currently available to the private sector then as in the case of a temporary supply shock the increased demand for borrowing to smooth the reduction in disposable income leads to a higher interest rate an open economy is different when faced with a temporary reduction in resources from either an adverse supply shock or a temporary increase in government spending the private sector in an open economy is able to borrow from abroad by running a balance of trade deficit if the country in question is a small part of the world economy the increased borrowing does not affect the world ex ante real interest rate so the effect on the country s ex ante real interest rate is nil returning to the case of a closed economy supply shocks and changes in government spending affect the ex ante real interest rate only if they are temporary if they were permanent consumers would not have the same incentive to borrow so the interest rate would tend to be constant

setup cost stability region for the dynamic lot sizing problem with backlogging abstract this paper develops a procedure to find the setup cost stability regions for the dynamic lot sizing problem with backlogging the setup cost stability region for a solution is defined as the set of all setup cost values for which the given solution is optimal such results can be useful in studying the robustness of a given solution with respect to errors in cost estimates

sources of output fluctuations in the united states during the inter war and post war years abstract this paper attempts to decompose the sources of fluctuations in industry output into 1 an aggregate national shock 2 industry group specific shocks and 3 idiosyncratic factors the empirical methodology is the engle watson dynamic mimic model the work is motivated as an attempt to compare empirically aggregate single factor theories of the cycle with real business cycle theories emphasizing technology shocks disaggregate data from the inter war and post war periods are examined conclusions on the relative importance of the various shocks seem to be dependent on the period being considered the single index theory of the cycle seems more appropriate for the inter war period

using stated preferences and beliefs to identify the impact of risk on poor households abstract whilst the importance of uncertainty in shaping economic behaviour of poor households is widely acknowledged empirically identifying the impact of risk is difficult by using data on risk preferences and perceptions of risk collected through hypothetical questions in combination with more traditional measures of a household s ability to deal with risk this article identifies the impact of risk on production decisions it shows both that data on stated preferences and beliefs can be usefully utilised to explain household behaviour and that risk has a significant impact on the production decisions of poor households

liquidity loanable funds and real activity abstract this paper develops a general equilibrium model of two traditional explanations of the monetary black box linking money and real activity the liquidity effect and the loanable funds effect these effects are modeled with a monetary production economy in which central bank injections of cash are funnelled into the economy through the credit market since only borrowers have direct access to the newly injected cash monetary injections cause nominal interest rates to fall if firms are borrowers then monetary injections also increase current and future real activity

econometric estimation of producers risk attitudes general methods are proposed for the identification and econometric estimation of the parameters of the distribution of risk attitudes in a producer population the proposed methods also provide the basis for the development of statistical tests of model specification and of behavioral hypotheses econometric risk attitude estimation is shown to be possible under less restrictive conditions than previously believed a moment based version of the general model is applied to indian data and the econometrically estimated risk attitudes are presented and compared to experimental results for a similar group of producers

the u s embargo act of 1807 its impact on new england money banking and economic activity the u s embargo act of 1807 its impact of new england money banking and economic activity i introduction the period 1793 through 1807 was one of unusual prosperity in the united states paced by the growth of american carrying and re export trade 1 the embargo act of 1807 however supposedly halted this period of growth and prosperity the act was an attempt by a new nation to persuade great britain and france to refrain from seizing neutral american ships by prohibiting the trading of certain goods between the united states and other countries the provisions of the act forbade u s ships to sail with cargoes to foreign ports the act was in effect from december 1807 through march 1809 historians generally assert that the embargo had at least three important consequences of the u s economy the embargo allegedly initiated a severe economic depression led to a signficant increase in the level of smuggling between the united states and other countries and was instrumental in bringing about an expansion of domestic manufacturing that started the united states on a path to self sufficiency with respect to the depression effects of the embargo mcmaster 1903 415 described the economic losses of the period as follows the newspapers were full of insolvent debtor notices all over the country the court house doors the tavern doors the post offices the cross road posts were covered with advertisements of sheriffs sales in the cities the jails were not large enough to hold the debtors at new york during 1809 thirteen hundred men were imprisoned for no other crime than being ruined by the embargo a traveler who saw the city in this day of distress assures us that it looked like a town ravaged by pestilence the counting houses were shut or advertised to let the coffee houses were almost empty the streets along the water side were almost deserted the ships were dismantled their decks were cleared their hatches were battened down illegal trade arose as people searched for other sources of income malone and rauch 1960 118 described the situation in the following manner the ancient art of smuggling was revived particularly along the land frontier with canada where drovers of wagon trains shot down federal agents and concerning the stimulative effect of the embargo upon the rise in domestic manufacturing north 1961 56 stated the closing off of the import trade was effective in promoting the rise of domestic manufactures and capital which had been devoted to shipping and foreign commerce was partially absorbed in a rapid growth of industry before 1808 only fifteen cotton mills had been built in the united states one in 1791 one in 1795 two more in 1803 and 1808 by the end of 1809 eighty seven additional mills had been constructed and capacity had been increased from eight thousand spindles in 1808 to thirty one thousand at the end of 1809 and an estimated eighty thousand by 1811 other branches of manufacturing also made substantial gains through 1814 similar comments concerning the embargo are abundant in most economic history texts and in numerous articles devoted to the subject while dramatic such discussion is based on casual empiricism at best and little in the way of rigorous economic analysis has ever been applied to discern the actual effects of the embargo upon the u s economy as usual with such historically remote events a paucity of data on such variables as real income output and employment constitutes the major obstacle to empirical analysis until recently economic historians have attempted to make inferences about the effects of the embargo upon the economy by relying primarily upon data reflecting the volume of import export and re export trade domestic and imported price indices and governmental duties 2 in a recent article for example frankel 1982 argues that an examination of british shipping statistics rather than those of the u

reserves announcements and interest rates does monetary policy matter the author provides evidence on the perceived existence of strong liquidity effect the analysis is based on the response of the term structure of interest rates to the weekly federal reserve announcements of bank reserves during the post october 1979 period it is shown that unanticipated changes in the mix between borrowed and nonborrowed reserves cause expected real interest rates to change after the announcement because they provide information about a future change in the supply of money a precise model is developed and tested during subperiods of nonborrowed and borrowed reserves targeting by the fed

the single product lot sizing problem with constant parameters and backlogging exact results a new solution and all parameter stability regions we consider the single product lot sizing problem over a finite planning horizon demand at each period is constant and excess demand is completely backlogged holding and backlogging costs are proportional to the amount of inventory stocked or backlogged while ordering cost is fixed independent of the quantity ordered the optimal policy targets to minimize the total relevant costs over the planning horizon the key results of this paper are 1 an explicit formula for the optimal total cost as a function of the model parameters and the number of cycles of the policy 2 a new polynomial time algorithm which determines the overall optimal policy and 3 stability regions for any solution considering simultaneous variations on all cost and demand parameters the proposed algorithm is easy to implement and therefore is suitable for practical use

locus of control and technology adoption in developing country agriculture evidence from ethiopia abstract we investigate the implication of farmers locus of control on their technology adoption decisions our empirical analysis is based on two longitudinal surveys and hypothetical choice exercises conducted on ethiopian farmers we find that locus of control significantly predicts farmers technology adoption decisions including use of chemical fertilizers improved seeds and irrigation we show that individuals with an internal locus of control have higher propensity of adopting agricultural technologies we observe these empirical regularities in both datasets and for both revealed measures of farmers technology adoption decisions as well as farmers hypothetical demand for agricultural technology the results hold even in a more conservative fixed effects estimation approach assuming locus of control as time variant and dynamic behavioral trait these findings provide behavioral and psychological explanations for the low rates of adoption of profitable agricultural technologies in sub saharan africa our results highlight that improving farmers non cognitive skills locus of control may facilitate technology adoption and agricultural transformation more generally the results suggest that anti poverty policies that only focus on relaxing short term external constraints including physical access to markets and technologies may not sufficiently alleviate agricultural underinvestment

the dynamics of a small open economy in response to monetary fiscal and productivity shocks abstract this paper evaluates empirically the relative importance of monetary and fiscal versus technology shocks in an open economy characterized by perfect international capital mobility the variance covariance matrix of these shocks is estimated a stochastic model is used to perform numerical simulations the results show that persistent shocks to productivity can reproduce several empirical regularities including the puzzling high correlation between national saving and investment remarkably well and that monetary and fiscal shocks play a minor role

wealth risk and activity choice cattle in western tanzania abstract imperfect credit markets force households to use their savings for investment profitable activities often require lumpy investments limiting entry by poorer households resulting in increasing welfare differences in tanzania cattle are a profitable but lumpy investment and a liquid asset for consumption smoothing richer households own substantial cattle herds while poorer households specialize in low return low risk activities a dynamic programming model and simulations are presented to analyze entry into asset accumulation under income risk the evidence suggests that households with lower endowments are less likely to own cattle and returns to their endowments are lower

tests of the relation between money and output in the real business cycle model abstract the paper contains tests of the relation between money and output implied by a real business cycle model the tests control for a variety that may affect economic growth and the growth rates of monetary aggregates using u s data from 1953 1 1984 4 we find almost no evidence that the empirical relations between real growth and measures of monetary policy violate the restrictions imposed by the model changes in a set of real variables explain a majority of the variation in gnp growth however substantial variation in gnp growth remains unexplained by the real factors that we consider

bank regulation and monetary policy the depository institutions deregulation and monetary control act 1980 and the garn st germain depository institutions act 1982 are the two most significant pieces of bank legislation since the 193os their significance stems from the fact that they have sought to roll back a number of the regulations and restrictions imposed on bank activity and competition in the 1933 80 period among the important provisions of these acts are a gradual elimination of regulation q ceilings on time and savings deposits by march 1986 the amelioration of state imposed usury ceilings on loans the nationwide provision of interest bearing transaction type accounts negotiable order of withdrawal now and super now accounts permission for thritts to expand into bank like products such as commercial and industrial loans consumer loans and credit cards and the development of new types of savings accounts such as mmdas l in addition to legislative deregulation we have also witnessed homemade deregulation as banks have sought to exploit often with great success loopholes in the bank holding

real wages over the business cycle a band spectrum approach this paper presents new evidence on the cyclical relationship between real wages and aggregate employment as is well known models that attribute fluctuations in output to movements in aggregate demand and retain the assumption of flexible product prices the adpf hypothesis imply countercyclical real wage movements as employment adjusts along a downward sloping aggregate demand for labor schedule in contrast real business cycle theories 10 15 13 suggest procyclical movements as workers substitute work for leisure along dynamic labor supply schedules the empirical evidence on these propositions remains mixed some influential studies report a negative relationship 4 5 25 others report a positive relationship 2 12 18 and geary and kennan gk 7 to identify the purely business cycle correlation and distinguish it from correlations at very high and very low frequencies the frequency domain decomposition provides a simple framework for reconciling the conflicting conclusions of previous studies and for focusing attention on the business cycle relationship i show that the highly significant positive or negative correlations reported in previous studies are attributable to variations at frequencies far too high or far too low to be associated with the business cycle the true business cycle relationship is quite different from that revealed by simple regressions of real wages on employment i find a weak but statistically significant negative relationship over business cycle frequencies for the post war u s data when wages are deflated by the producer price index ppi the negative relationship is particularly strong over the subperiod 1947 70 but becomes weak and insignificant over the last sixteen years 1971 86 this finding is consistent with the widely held belief that in the former period cyclical movements in employment were determined by changes in aggregate demand while real shocks dominated in the 1970s however when wages are deflated by the consumer price index cpi the business cycle relationship is weak and not statistically significant over both subperiods these results contrast sharply with those of previous studies that do not isolate business cycle components

money velocity in an endogenous growth business cycle with credit shocks the explanation of velocity has been based in substitution and income effects since keynes s 1923 interest rate explanation and friedman s 1956 application of the permanent income hypothesis to money demand modern real business cycle theory relies on a goods productivity shocks to mimic the data s procyclic velocity feature as in friedman s explanation while finding money shocks unimportant and not integrating financial innovation explanations this paper sets the model within endogenous growth and adds credit shocks it models velocity more closely with significant roles for money shocks and credit shocks along with the goods productivity shocks endogenous growth is key to the construction of the money and credit shocks since they have similar effects on velocity through substitution effects from changes in the nominal interest rate and in the cost of financial intermediation but opposite effects upon growth through permanent income effects that are absent with exogenous growth

risk attitudes and economic well being in latin america abstract a common conjecture in both the theoretical and policy literatures on development is that people remain poor because they are too impatient and risk averse to accumulate the resources needed to improve their well being the empirical literature however suggests that this conjecture is far from proven we sample more than 3000 participants drawn representatively from six latin american cities and find little correlation between baseline risk aversion and well being measured as an index of eight outcomes we do however find that measures of ambiguity aversion loss aversion and the willingness to take advantage of a risk pooling scheme all correlate with well being participants who are ambiguity averse loss averse and who react conservatively in the risk pooling condition all have significantly lower scores on our well being index these results are robust to the inclusion of a variety of important controls like human capital accumulation and access to credit

money and interest in a cash in advance economy the authors analyze an aggregative general equilibrium model in which the use of money is motivated by a cash in advance constraint applied to purchases of a subset of consumption goods the system is subject to both real and monetary shocks which are economy wide and observed by all they develop methods for verifying the existence of characterizing and explicitly calculating equilibria copyright 1987 by the econometric society

household credit and the monetary transmission mechanism this paper evaluates the importance of household credit in the transmission of monetary policy and explaining the positive correlation between money and credit services over the business cycle it does so in the context of a general equilibrium framework with an explicit financial sector within this sector there are firms which specialize in the production of household credit services and financial intermediaries who provide interest bearing accounts for households and loanable funds to credit producers it is shown that monetary injections which occur through the financial sector can generate a liquidity effect that positively influences the availability of household credit services and overall real activity furthermore the model predicts that liquidity effects working through this channel lowers the real costs associated with consumption and can quantitatively dominate the anticipated inflation effect thus resolving a difficulty with recent liquidity effects models which emphasize only the business lending channel

anticipated inflation and the capital stock in a cash in advance economy abstract an economy is constructed in which the steady state capital stock is inversely related to the rate of inflation as a result that is directly opposite the usual conclusion

intermediate monetary targets and macroeconomic fluctuations it is investigated whether the choice of intermediate target has altered macroeconomic fluctuations and whether the observed changes are consistent with predictions from economic theory since implications from the theoretical literature focus on the effects of structural disturbances an empirical analysis must identify these effects the structural vector autoregressive var technique estimates structural disturbances using restrictions from standard macroeconomic theory based on descriptions of actual targeting procedures by insiders to federal reserve policy decisions the intermediate target for the united states is identified as the interest rate from 1951 to 1969 and money from 1970 to 1986 var models are estimated over each subsample to assess whether the estimated structural disturbances cause endogenous variables to behave as economic theory predicts tests are also performed to assess whether or not the targeting rule affects the variance of endogenous variables attributable to structural sh

time to implement and aggregate fluctuations in this paper we slightly modify the canonical rbc model by adding an implementation lag in the technology to reproduce the fact that consumption is a leading indicator of output indeed we assume that agents have today some information on the realization of the technology shock that will occur tomorrow today inventions are known and give information on the innovations which will be implemented tomorrow the model is estimated and tested on us data by a simulated method of moments using some suitable reconstructed data that are compatible with that model the results are in favor of this implementation lag hypothesis the model is not rejected by us post war data

inflation investment and growth a money and banking approach output growth investment and the real interest rate in long run evidence tend to be negatively affected by inflation theoretically inflation acts as a human capital tax that decreases output growth and the real interest rate but increases the investment rate opposing evidence this paper resolves this puzzle by requiring exchange for investment as well as consumption inflation then decreases the investment rate and still decreases both output growth and real interest up to some moderately high rate of inflation above which increasingly low investment finally causes capital to fall relative to labour and the real interest rate to rise

an inquiry into the sources of macroeconomic fluctuations abstract this paper attempts to decompose the sources of fluctuations in quarterly employment by industry and region into 1 an aggregate national shock 2 region specific shocks 3 industry specific shocks and 4 idiosyncratic factors the empirical analysis is motivated by a dynamic theory of the business cycle the empirical methodology is the engle watson dynamic mimic model implemented via the em algorithm the work is motivated as an attempt to compare empirically aggregate single factor theories of the cycle with real business cycle theories emphasizing industrial or regional shocks

time to change what to sow risk preferences and technology adoption decisions of cotton farmers in china this paper examines the role of individual risk attitudes in the decision to adopt a new form of agricultural biotechnology in china i conducted a survey and a field experiment to elicit the risk preferences of chinese farmers who faced the decision of whether to adopt genetically modified bt cotton a decade ago in my analysis i expand the measurement of risk preferences beyond expected utility theory to incorporate prospect theory i find that farmers who are more risk averse or more loss averse adopt bt cotton later farmers who overweight small probabilities adopt bt cotton earlier

non nested tests of three competing theories of business cycles this paper tests the keynesian new classical and real business cycle theories against each other as non nested hypotheses using quarterly data for the us covering the period 1959 1 1989 2 the results indicate that no one theory stands out as the dominant explanation of the business cycle this contrasts with the findings of earlier work which is mostly concerned with testing the keynesian against the new classical theory we find that the introduction of a third theory the real business cycle theory which accounts of real factors blurs the distinction between the demand sided keynesian and the new classical theories

unexpected monetary disturbances during the gold standard era abstract this empirical paper uses the barro methodology of estimating unexpected monetary shocks to determine the effect these shocks had on real output in the u s during the gold standard era between 1880 and 1913 it also investigates whether changes in a measure of financial intermediation had real effects the results indicate that neither expected nor unexpected money shocks affected output changes in financial intermediation however were significantly correlated with output this result lends support to theories which stress the endogeneity of broad measures of the money supply

the role of education in facilitating risk taking and innovation in agriculture the impact of education on farmers attitudes toward endogenous risk measured using an attitude survey instrument is estimated with household data from rural ethiopia education of the household head is found to decrease risk aversion next the effects of education and risk attitudes on technology adoption are estimated schooling encourages farmers to adopt innovations whereas risk aversion reduces the probability of adoption thus we find that schooling encourages innovation a potentially risky undertaking not only directly but also indirectly through its effect upon attitudes toward risk to the extent that educated farmers are early innovators and are copied by those with less schooling as other research on the same data has shown the reduction of riskaversion not only has private benefits for those with education but also may have externality benefits

macroeconomic activity and monetary policy actions some preliminary evidence monetary policy is conducted through open market operations loans at the discount window and changes in the reserve requirement structure the purpose of this paper is to formally investigate the notion that the effect of changes in reserve requirement ratios is different from the effect of other policy tools this is accomplished by decomposing the monetary base into those changes caused by changes in reserve requirement ratios and those caused by other monetary policy actions some preliminary evidence suggesting differential real effects from the policy tools is provided copyright 1992 by ohio state university press

the failure of competition in the credit card market the bank credit card market containing 4 000 firms and lacking regulatory barriers casually appears to be a hospitable environment for the model of perfect competition nevertheless this article reports that credit card interest rates have been exceptionally sticky relative to the cost of funds moreover major credit card issuers have persistently earned from three to five times the ordinary rate of return in banking during the periods 1983 88 the failure of the competitive model appears to be partly attributable to consumers making credit card choices without taking account of the very high probability that they will pay interest on their outstanding balances copyright 1991 by american economic association

nonstructural risk attitude estimation this paper presents an econometric approach to risk attitude estimation that does not require joint estimation of the structure of the firm s technology and input decision rules the nonstructural approach replaces optimal input choice with the assumption that farmers optimally manage their portfolios of productive activities by thus shifting the focus from the detailed production decisions of the farm manager to the net returns of the whole farm operation the modeling problem is simplified the nonstructural approach is used to estimate risk attitudes in three indian villages the results are compared to previous experimental and econometric estimates from the same villages

demand shocks supply shocks and the cyclicality of real wages the behaviour of real wages over the business cycle has received increasiing attention in recent years the cyclicality of real wages constitues an important aspect of recent models of the business cycle however empirical studies undertaken to determine whether real wages are procyclical or countercyclical have reported conflicting findings in thiis paper we use vector autoregressions to analyse the cyclicality of real wages we find that the source of the disturbance plays a decisive role in the cyclical behaviour of real wages in particular we demonstrate that a supply shock generates procyclical real wages whereas a demand shock yields countercyclicality

the source of fluctuations in money evidence from trade credit abstract this paper tests the relative importance of technology shocks and financial shocks as sources of fluctuations in money the model extends the theory of king and plosser 1984 by recognizing that both money and trade credit provide transactions services under certain conditions the co movements between money and trade credit can reveal the nature of the underlying shocks the empirical results strongly suggest that shocks to the financial system account for most of the fluctuations in money in the long run and at business cycle frequencies on the other hand technology shocks appear to be more important at seasonal frequencies

endogenous monetary policy and the business cycle the correlations and volatilities of real variables seem to be stable over time but the relation between real and nominal variables is unstable presumably one important factor behind this observation is the nature of money supply in this paper i look at a business cycle model where the central bank sets money supply to minimize the volatility of in ation and output i nd that small changes in the central bank s preferences can generate large changes in the derived money supply rule and in correlations between real and nominal variables although wages are assumed to be sticky changes in the money supply rule do not generate any major changes in the behavior of real variables 2000 elsevier science b v all rights reserved jel classixcation e32 e52

the cyclical behavior of household and business investment in a cash in advance economy abstract this paper focuses on a monetary explanation of two business cycle regularities i business and household investment are positively correlated and procyclical and ii business investment tends to lag household investment over the cycle our general equilibrium framework is essentially a standard cash in advance economy where households purchase both non durable and durable consumption goods and businesses accumulate productive capital financial intermediaries provide interest bearing deposits to households and loanable funds to finance business investment it is shown that the adaptation of particular interest rate rules by the monetary authority provides a mechanism to capture both the timing and direction of business and household investment the results are then discussed within the context of recent limited participation models which emphasize the liquidity effects of monetary shocks

productivity shocks and business cycles this note uses two measures of productivity growth the solow residual and the dual residual from the cost function to test competing theories of the cycle in a number of oecd countries the empirical results indicate that both demand and supply shocks play a role in driving economic cycles and therefore refute the stronger real business cycle hypothesis

financial innovation price smoothing and monetary policy financial innovation price smoothing and monetary policy i introduction in a monetary economy the volume of nominal transactions fluctuates with the level of economic activity empirical evidence suggests that the supply of nominal transaction assets such as currency and bank deposits also fluctuates with the level of economic activity some researchers have attributed these observations to the phenomenon of money endogeneity 1 one explanation for this endogenous supply response is a systematic monetary policy as described by black 1972 under which the central bank passively adjusts the money supply to accommodate the changes in money demand alternatively king and plosser 1984 and saving 1979 stress the role of the private banking system in producing this endogenous response they argue that exogenous changes in real activity elicit sympathetic changes in the demand for transaction services that may be partially or fully accommodated by the banking system through its supply of inside money in either case this endogenous supply response tends to mitigate the price adjustment that accompanies a real supply shock 2 in the long run however the price level is ultimately determined by the central bank in the market for the nominal quantity that it controls e g currency bank reserves when deposit accounts are subject to reserve requirements or the monetary base 3 this suggests that if the private banking system does not fully accommodate the real shock and if the shock exhibits a well defined persistence then endogenous price adjustments that are fully anticipated may be further damped by a passive supply response by the central bank in addition if price expectations affect real interest rates then current period price level smoothing via a passive monetary policy may also be possible 4 in addition to employing transaction assets currency and checkable bank deposit accounts to meet their transaction requirements agents may purchase non deposit transaction services directly for firms these services include the tools available to the modern corporate cash manager such as lockbox collection systems repurchase agreements and zero balance accounts in the household sector they take the form of atms debit and credit cards and overdraft privilages on checkable accounts among others these non deposit transaction services represent an increasingly important medium of exchange their supply by the banking system is not directly controlled by the central bank and also offers another avenue by which the economy may respond endogenously to fluctuating transaction requirements associated with real shocks thereby further mitigating the price adjustment 5 the production of non deposit transaction services is subject to technology shocks in the form of financial innovations these innovations alter the economy wide demand for currency and checkable bank deposit accounts and prices adjust as with the introduction of new technology into the production of goods financial innovations are not fully adopted immediately due to the fixed costs of adjusting individual cash management practices but are instead assimilated over time this implies that their effects on transaction asset demands persist if the rate of adoption has a forecastable component the central bank can smooth expected prices by passively accommodating these innovations as with aggregate productivity shocks this persistence may also enable the central bank to damp the disturbances to the current period price level that these innovations create through the impact of price expectations on real interest rates this paper examines a non deposit transaction services market in a model economy that is developed in section ii it has the following features transactors can meet their transaction requirements by allocating wealth to currency or to bank deposit accounts that pay a market determined interest rate or by purchasing non deposit transaction services directly at a market determined price

trade interdependence and the international business cycle a stochastic general equilibrium model of the world economy is developed to analyze the contribution of trade interdependence to international business cycles we test some of the implications of the model using data from ten major industrial countries and a variety of detrending techniques to calculate the cyclical component of output we find that the significance of trade in the transmission of economic disturbances across countries is not robust to the choice of the detrending method in general the role of trade interdependence is moderate and seem to have been stronger in the period before 1973

dynamic version of the economic lot size model this article originally appeared in management science october 1958 volume 5 number 1 pp 89 96 published by the institute of management sciences a forward algorithm for a solution to the following dynamic version of the economic lot size model is given allowing the possibility of demands for a single item inventory holding charges and setup costs to vary over n periods we desire a minimum total cost inventory management scheme which satisfies known demand in every period disjoint planning horizons are shown to be possible which eliminate the necessity of having data for the full n periods

real business cycles in this paper we demonstrate how certain very ordinary economic principles lead maximizing individuals to choose consumption production plans that display many of the characteristics commonly associated with business cycles our explanation is entirely consistent with i rational expectations ii complete current information iii stable preferences iv no technological change v no long lived commodities vi no frictions or adjustment costs vii no government viii no money and ix no serial dependence in the stochastic elements of the environment we also provide a completely worked out example of the type of artificial economy we have in mind the time series properties of the example exhibit some major features of observed business cycles although this type of model may not be capable of explaining all of the regularities in actual business cycles we believe that it provides a useful well defined benchmark for assessing the relative importance of factors e g monetary disturbances

credit rationing and effective supply failures the topic of this paper is among the oldest and most fundamental in monetary theory how and why does monetary policy affect real economic activity traditional answers hold that the central bank can manipulate aggregate demand by engineering expansions or contractions of the medium of exchange in its monetarist variant this story posits a direct link between something called m and aggregate spending in its keynesian variant the story holds that adjustments in asset prices brought about by a change in m lead to more spending especially on capital goods in either case short run stickiness of prices is needed to translate some of the changes in demand into movements of real output in recent years these conventional stories have become increasingly implausible as stiglitz and i blinder and stiglitz i 983 have argued elsewhere with money becoming more and more difficult to define it is becoming increasingly difficult to believe that the central bank can cause a recession by contriving a shortage of an arbitrary subset of assets called m put differently the point seems both simple and compelling if there are ready substitutes for money control of money will not give the authorities much leverage over the real economy hence this paper develops an explanation for how central bank policy affects

lab and life does risky choice behaviour observed in experiments reflect that in the real world risk preferences play a crucial role in a great variety of economic decisions measuring risk preferences reliably is therefore an important challenge in this paper we ask the question whether risk preferences observed in economic experiments reflect real life risky choice behaviour we investigate in a sample representative for a rural region of eastern uganda whether pursuing farming strategies with both a higher expected profit and greater variance of profits is associated with willingness to take risks in an experiment controlling for other determinants of risk taking in agriculture we find that risky choice behaviour in the experiment is correlated with risky choice behaviour in real life in one domain i e the purchase of fertiliser but not in other domains i e the growing of cash crops and market orientation more broadly our findings suggest that economic experiments may be good at capturing real world risky choice behaviour that is narrowly bracketed

an exogeneity test for a simultaneous equation tobit model with an application to labor supply a test of weak exogeneity in the simultaneous equation tobit model is proposed and illustrated using a female labour supply model estimated using cross section data the test statistic can be simply output from any standard tobit maximum likelihood package and is asymptotically efficient the procedure provides consistent estimators for the simultaneous tobit model whose asymptotic covariance matrix is a simple extension of the usual tobit formula we also provide the lagrange multiplier test of weak exogeneity this abstract was borrowed from another version of this item
