demand for money in open economies abstract the demand for real cash balances deduced from an underlying portfolio model of the financial market is shown to depend upon domestic variables and foreign monetary developments the model is estimated using quarterly postwar data for canada germany uk and us there is clear evidence that demand for money is affected not only by changes in domestic variables such as permanent income domestic interest rate and price expectations but also by fluctuations in exchange rate expectations and foreign interest rates the conclusion that domestic monetary policy is fairly ineffective and domestic financial markets are highly vulnerable to changes in foreign financial and monetary developments need to be modified in light of the results presented in this paper

the control of technology alliances an empirical analysis of the biotechnology industry we examine the determinants of control rights in biotechnology alliances through three case studies and a quantitative analysis aghion and tirole 1994 argue that control rights will be assigned so as to maximize the value of the final output as long as the r d firm has sufficient financial resources consistent with this framework the allocation of control rights to the r d firm increases with the firm s financial resources the empirical evidence regarding the relationship between control rights and the stage of the project at the time the alliance is signed is more ambiguous

an econometric study of co2 emissions energy consumption income and foreign trade in turkey abstract this study attempts to empirically examine the dynamic causal relationships between carbon emissions energy consumption income and foreign trade in the case of turkey using the time series data for the period 1960 2005 this research tests the interrelationship between the variables using the bounds testing to cointegration procedure the bounds test results indicate that there exist two forms of long run relationships between the variables in the case of first form of long run relationship carbon emissions are determined by energy consumption income and foreign trade in the case of second long run relationship income is determined by carbon emissions energy consumption and foreign trade an augmented form of granger causality analysis is conducted amongst the variables the long run relationship of co2 emissions energy consumption income and foreign trade equation is also checked for the parameter stability the empirical results suggest that income is the most significant variable in explaining the carbon emissions in turkey which is followed by energy consumption and foreign trade moreover there exists a stable carbon emissions function the results also provide important policy recommendations

economic reforms and long run money demand in china implications for monetary policy although money demand equations have been estimated for many western countries only recently have researchers investigated the demand for money in centrally planned economies like china chow 7 who helped pioneer the analysis of chinese macro data estimates a simple money demand function derived from the quantity theory using annual data from 1952 through 1983 he concludes that the quantity theory provides a reasonable first approximation in explaining the demand for money in china 7 325 portes and santorum 27 use real and nominal adjustment specifications and test for the homogeneity of money demand with respect to the price level and real income feltenstein and farhadian 11 estimate a money demand function based on cagan s 3 work and blejer et al 1 estimate an error correction model using data for only the 1980s both studies find that the demand for real balances is explained by real income and an opportunity cost measure

residential electricity demand dynamics in turkey abstract this article provides fresh empirical evidences for the income and price elasticies of the residential energy demand both in the short run and long run for turkey over the period 1968 2005 using the bounds testing procedure to cointegration the computed elasticities of income and price are consistent with the previous studies and as expected the long run elasticities are greater than the short run elasticities an augmented form of granger causality analysis is implemented among residential electricity income price and urbanization in the long run causality runs interactively through the error correction term from income price and urbanization to residential energy but the short run causality tests are inconclusive the parameter stability of the short run as well as long run coefficients in the residential energy demand function are tested the results of these tests display a stable pattern

stability of the money demand function in asian developing countries previous studies that estimated the money demand function in asian developing countries either employed traditional estimation techniques or recently popularized cointegration technique while the first group suffers from spurious regression problems the second group interpreted their finding of cointegration as a sign of stability of estimated parameters this study after incorporating the cusum and cusumsq tests into cointegration analysis shows that in some asian countries even though real m1 or m2 monetary aggregates are cointegrated with their determinants the estimated parameters are unstable

episodes of war and peace in an estimated open economy model we analyze the effects of world wars on the macroeconomic dynamics of the u s france germany and the uk by means of an estimated open economy model the model allows wars to affect the economy through capital depreciation sovereign default a military draft household preferences and spillovers on other exogenous processes productivity investment trade policy variables if the bulk of fluctuations during war episodes can be explained by the rise in government spending in the u s other factors are crucial in other countries we also discuss the size and state dependence of public spending multipliers and a counterfactual welfare exercise

long run income and interest elasticities of money demand in the united states econometric techniques designed to accommodate nonstationary data are used to reexamine the stability of interest and income elasticities of money demand in the united states estimates based on postwar monthly data reveal a stable relationship between m1 velocity and various measures of interest rates that proxy the opportunity cost of holding money balances tests for the existence of cointegration and methods used to estimate the income and interest elasticities are based on procedures prescribed by soren johansen 1988 corresponding error correction estimates offer insight as to the dynamics of the process that maintains the equilibrium relation between velocity and interest rates copyright 1991 by mit press

wars and capital destruction abstract in this paper we propose a theoretical framework to investigate the impact of conflicts and wars on key macroeconomic aggregates and welfare using a panel data with 9 countries from 1870 onwards we first show that the consumption to output ratio is minimal during wwii for participants while this can be explained by an increase in public spending in the usa this cannot be the case in other countries that participated in wwii as they experience a large fall in output during wartime to account for this we build a variation of a real business cycle model first proposed by hercowitz and sampson 1991 we extend the initial model to account for specific shocks that destroy private and public capital stocks as conflicts do by assuming an exogenously time varying parameter in the law of capital accumulation in addition the model imbeds generalized tfp shocks capturing standard technological factors as well as the potential effects of war on the labor force the model is estimated and used i to assess the importance of capital shocks during war episodes and ii to quantify the welfare effects of conflicts we show that capital shocks are crucial to account for the macroeconomic dynamics of countries that have experienced large war related destruction and that the welfare losses from fluctuations can be quite large when considering data samples that include major war episodes

asset pricing and the propagation of macroeconomic shocks this paper considers the implications of habit formation and financial frictions for the propagation of macroeconomic shocks in a model that is capable of matching asset pricing moments a short lived shock that destroys a small fraction of the economy s stock of pledgeable collateral generates a persistent recession a stock market crash and a flight to safety effect this novel mechanism creates a tight link between the asset pricing implications of macroeconomic models and their ability to propagate and amplify the effects of macroeconomic shocks

economic policies and demand for money evidence from canada this study identifies canadian fiscal and monetary policy regime changes that could influence the services of money it is argued that if these policy regime changes were not incorporated in the estimation of demand for real balances the resulting estimate would be biased and unstable using canadian monthly data for the january 1975 to june 2001 period the paper estimates a standard demand for money m1 function with and without these policy regime changes it was found the demand for money in canada is stable over the short and long run periods when these policy regime changes are incorporated and the estimated coefficients have correct signs

stochastic depreciation and the business cycle the authors study a version of the neoclassical growth model in which shocks to both aggregate productivity and the depreciation of capital generate fluctuations around the steady state growth path depreciation shocks induce an inverse comovement between average labor productivity and hours worked when the model is calibrated to u s data it generates a correlation between productivity and hours which is significantly closer to the observed value than that of standard real business cycle models furthermore the addition of depreciation shocks does not cause a deterioration of the predictions of the model concerning other comovements copyright 1994 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

multilateral contracting and the employment relationship this paper studies the structure of the employment relationship in organizations it investigates the trade off firms face between making commitments to their workforce as a whole multilateral relational contracts and making more limited commitments to individuals or smaller groups of employees bilateral relational contracts multilateral contracts bind the firm more strongly to implicit commitments improving motivation but are difficult to adjust in response to changes in the environment bilateral contracts make workforce changes easier to implement the framework helps to explain the use of relative performance evaluation why firms rely on temporary employees and the adoption of two tier workforces

university innovation and the professor s privilege national policies take varied approaches to encouraging university based innovation this paper studies a natural experiment the end of the professor s privilege in norway where university researchers previously enjoyed full rights to their innovations upon the reform norway moved toward the typical u s model where the university holds majority rights using comprehensive data on norwegian workers firms and patents we find a 50 decline in both entrepreneurship and patenting rates by university researchers after the reform quality measures for university start ups and patents also decline applications to literatures on university technology transfer innovation incentives and taxes and entrepreneurship are considered

propagation and smoothing of shocks in alternative social security systems abstract even with well developed capital markets there is no private market mechanism for trading between current and future generations this generates a potential role for public old age pension systems to spread economic and demographic shocks among different generations this paper evaluates how different systems smooth and propagate shocks to productivity fertility mortality and migration in a realistic olg model we use reductions in the variance of wealth equivalents to measure performance starting with the existing u s system as a unifying framework in which we vary how much taxes and benefits adjust and which we then compare to the existing german and swedish systems we find that system design and shock type are key factors the german system and the benefit adjustment only u s system best smooth productivity shocks which are by far the most important shocks overall the german system performs best while the swedish system which includes a buffer stock to relax annual budget constraints performs rather poorly focusing on the u s system reliance solely on tax adjustment fares best for mortality and migration shocks while equal reliance on tax and benefit adjustments is best for fertility shocks

german monetary unification and the stability of the german m3 money demand function abstract this paper employs quarterly data from the whole of germany to test the stability of m3 demand for money the methodology is based on an application of the cusum and cusumsq in the context of error correction modeling and cointegration the results reveal some instability in m3 money demand function

empirical study on the environmental kuznets curve for co2 in france the role of nuclear energy this paper attempts to estimate the environmental kuznets curve ekc in the case of france by taking the role of nuclear energy in electricity production into account we adopt the autoregressive distributed lag ardl approach to cointegration as the estimation method additionally we examine the stability of the estimated models and investigate the granger causality relationships between the variables in the system the results from our estimation provide evidence supporting the ekc hypothesis and the estimated models are shown to be stable over the sample period the uni direction running from other variables to co2 emissions are confirmed from the casualty tests specifically the uni directional causality relationship running from nuclear energy to co2 emissions statistically provides evidence on the important role of nuclear energy in reducing co2 emissions

patents and patent policy a patent is the legal right of an inventor to exclude others from making or using a particular invention this right is sometimes termed an intellectual property right and is viewed as an incentive for innovation this article surveys the evidence on patent effectiveness in encouraging innovation and reviews the current controversies in patent policy

can world real interest rates explain business cycles in a small open economy abstract while the world real interest rate is potentially an important mechanism for transmitting international shocks to small open economies much of the recent quantitative research that studies this mechanism concludes that it has little effect on output investment and net exports we re examine the importance of world real interest rate shocks using an approach that reverses the standard real business cycle methodology we begin with a small open economy business cycle model but rather than specifying the stochastic processes for the shocks and then solving and simulating the model to evaluate how well these shocks explain business cycles we use the model to back out the shocks that are consistent with the model s observable endogenous variables then we use variance decompositions to examine the importance of each shock we apply this methodology to canada and find that world real interest rate shocks can play an important role in explaining the cyclical variation in a small open economy in particular they can explain up to one third of the fluctuations in output and more than half of the fluctuations in net exports and net foreign assets

endogenous capital depreciation and technology shocks i examine the dynamic impact of capital maintenance on key aggregates through the depreciation rate i find that two factors are crucial for the short run effects of total factor productivity and investment specific shocks i the marginal efficiency of maintenance and its connection with the rate of utilization and ii the interplay between the intertemporal effect of maintenance and the substitution effect between maintenance and utilization the latter is expressed by the relative size of the elasticity of maintenance to the hicksian elasticity of complementarity between maintenance and utilization these theoretical results suggest that to match the observed responses of the macroeconomic aggregates the sign of the cross derivative should be negative and that the relative size of the hicksian elasticity should be smaller than the maintenance elasticity of marginal depreciation finally the model suggests that the main macroeconomic aggregates react procyclically with the exception of maintenance the behavior of which depends on the type of the shock

capital utilization economic growth and convergence abstract optimal decisions by economic agents regarding the utilization of capital lead to empirically plausible speeds of convergence in one sector models of economic growth the relationship between depreciation and capital utilization plays a crucial role in slowing down convergence to the steady state cross country differences in the extent to which the capital utilization decision is internalized along the transition path may lead to differences in convergence rates even for countries with similar initial and terminal conditions finally by assuming a constant depreciation rate and full capital utilization standard growth models may be overstating the magnitude of the steady state equilibrium

has fiscal policy helped stabilize the postwar u s economy abstract in this paper i consider whether postwar fiscal policy has helped stabilize the u s economy i do this by adding to the stochastic growth model fiscal policy feedback rules estimated from postwar data these rules allow fiscal policies to respond to current and lagged output and labor hours i use the estimated policy rules to see if postwar fiscal policy reduces output volatility and or lengthens expansions and shortens recessions i find that fiscal policy in general provides little stability on either count i also find that the endogenous feedback links by themselves can provide some stabilization

a penny for your quotes patent citations and the value of innovations the use ofpatents in economic research has been seriously hindered by the fact that patents vary enormously in their importance or value and hence simple patent counts cannot be informative about innovative output the purpose of this article is to put forward patent counts weighted by citations as indicators of the value of innovations thereby overcoming the limitations of simple counts the empirical analysis of a particular innovation computed tomography scanners indeed shows a close association between citation based patent indices and independent measures of the social value of innovations in that field moreover the weighting scheme appears to be nonlinear increasing in the number of citations implying that the informational content of citations rises at the margin as in previous studies simple patent counts are found to be highly correlated with contemporaneous rd however here the association is within afield over time rather than cross sectional

parameter drifts misspecification and the real exchange rate in emerging countries abstract this paper reviews the baseline framework for the analysis of emerging economies using argentinean data i estimate a small open economy model with stochastic trend working capital constraint and augmented with time varying parameters i find that structural technological and financial parameters of one sector model are time varying during 1936 2006 time varying parameters correlate with the real exchange rate suggesting potential misspecification of the one sector model therefore i propose a two sector model that endogenously accounts for the real exchange rate in this model stationary productivity shocks and the country premium together explain a large share of the variability observed in the data

the stability of long run money demand in five industrial countries abstract this study provides strong evidence for the stability of long run demand functions for narrowly defined money m1 in five industrial countries u s japan canada u k and west germany using post war quarterly data evidence of stability is examined using two different estimation techniques and through a formal test of parameter constancy designed specifically for cointegrating vectors in the majority of these countries the key to stability is the imposition of a unitary long run income elasticity that is rarely rejected by the data

cointegration tests of a long run relation between money demand and the effective exchange rate abstract for the period starting with the floating of the us dollar we find evidence that long run stationarity of the demand function for m2 but not m1 requires inclusion of the effective exchange rate these results lend some support to mckinnon s hypothesis that nonstationarity in the demand for money can be resolved by inclusion of the exchange rate jel f41 e41

exchange rate sensitivity of demand for money and effectiveness of fiscal and monetary policies one of the arguments between proponents and opponents of floating exchange rates centres around the relative effectiveness of fiscal and monetary policy while proponents of floating rates argue that monetary policy is more effective under floating rates its opponents contend that fiscal policy is more effective under fixed rates however economic theory suggests that there is room for both policies under both types of exchange rate system depending upon degree of sterlization concentrating on the floating rates mundell 1963 has argued that the relative effectiveness of monetary and fiscal policies would also depend upon sensitivity of money demand to exchange rate more precisely he has conjectured that the demand for money is likely to depend upon the exchange rate in addition to the interest rate and the level of income this would slightly reduce the effectiveness of a given change in the quantity of money and slightly increase the effectiveness of fiscal policy on income and employment under

the demand for money in the united states evidence from cointegration tests this paper uses recent cointegration test procedures to investigate the underlying economic relationship between real money balances real income and interest rates for the united states unlike recent studies of money demand the authors analysis uses quarterly data spanning the period 1915 88 thus providing a sample encompassing a wide variety of economic experiences the evidence presented indicates that the broader m2 measure of money is the preferable measure with which to consider the long run effects of monetary policy copyright 1991 by ohio state university press

using theory for measurement an analysis of the cyclical behavior of home production abstract a significant amount of economic activity takes place within the home unfortunately it is difficult to assess the cyclical properties of home production because the available data are too sporadic using a real business cycle rbc model we construct quarterly data on three variables that are unobservable at a quarterly frequency hours worked in the home sector hours spent in leisure and the consumption of home produced goods three results emerge leisure is countercyclical while nonmarket hours are acyclical hours spent in home production have declined significantly since the 1970s fluctuations in market output are a good measure of fluctuations in individual utility as long as home and market consumption are either extreme complements or extreme substitutes in the production of utility

fiscal spending shocks endogenous government spending and real business cycles abstract we analyze a real business cycle model in which the government optimally chooses public investment and nonmilitary current expenditures to maximize the welfare of the representative private agent we characterize the optimal response of endogenous spending to shocks to technology and to military expenditures comovements between the components of government spending and other macroeconomic aggregates predicted by the model are compared with the corresponding comovements in the u s data the model captures the qualitative features of the relative volatilities of the components of government spending quite well but predicts too high correlations between the components of government spending and output
