capital utilization and the foundations of club convergence abstract multiple steady states may arise in standard neoclassical growth models if the savings rate of wage income exceeds that of capital income this paper shows that endogenous capital utilization may produce such savings behavior in an otherwise standard solow model

what type of finance matters for growth bayesian model averaging evidence this paper examines the effect of finance on long term economic growth using bayesian model averaging to address model uncertainty in cross country growth regressions the literature largely focuses on financial indicators that assess the financial depth of banks and stock markets these indicators are examined jointly with newly developed indicators that assess the stability and efficiency of financial markets once the finance growth regressions are subjected to model uncertainty the results suggest that commonly used indicators of financial development are not robustly related to long term growth however the findings from the global sample indicate that one newly developed indicator the efficiency of financial intermediaries is robustly related to long term growth

financial intermediation and endogenous growth an endogenous growth model with multiple assets is developed agents who face random future liquidity needs accumulate capital and a liquid but unproductive asset the effects of introducing financial intermediation into this environment are considered conditions are provided under which the introduction of intermediaries shifts the composition of savings toward capital causing intermediation to be growth promoting in addition intermediaries generally reduce socially unnecessary capital liquidation again tending to promote growth

stock markets banks and growth panel evidence this paper investigates the impact of stock markets and banks on economic growth using a panel data set for the period 1976 98 and applying recent gmm techniques developed for dynamic panels on balance we find that stock markets and banks positively influence economic growth and these findings are not due to potential biases induced by simultaneity omitted variables or unobserved country specific effects

measuring the business cycle effects of permanent and transitory shocks in cointegrated time series abstract this paper proposes a statistical framework to evaluate the contribution of permanent and transitory shocks to the cyclical fluctuations of cointegrated variables an empirical application with us macroeconomic data reveals that transitory shocks are responsible for most of the variability at the business cycle frequencies

an unobserved components model that yields business and medium run cycles we generalize the unobserved components uc model to allow the permanent component to have different dynamics than the transitory components when decomposing u s economic activity using a multivariate uc model of log output consumption and investment we find that these proposed dynamics in the permanent component are statistically significant and distinct from those of the transitory components our approach provides an alternative explanation for the growth cycles identified by comin and gertler 2006 that is related to the cyclical movements in technology in a framework consistent with the beveridge and nelson 1981 decomposition

multivariate detrending under common trend restrictions implications for business cycle research abstract this paper outlines a methodology to detrend multiple time series under common trend restrictions the same filters used to construct the estimated trend in univariate exercises are shown to be appropriate in multivariate studies with a single common trend however to estimate the common trend in the multivariate case the filter is applied to a linear combination of series rather than to each series individually an empirical example and simulation exercises illustrate the implications of common trend detrending for measurement of business cycle properties

costly monitoring financial intermediation and equilibrium credit rationing abstract this paper establishes a link between equilibrium credit rationing and financial intermediation in a model with asymmetrically informed lenders and borrowers costly monitoring and investment project indivisibilities intermediation is shown to dominate borrowing and lending between individuals and these financial intermediaries exhibit several of the important features of intermediaries as we know them equilibrium interest rates and the aggregate quantity of loans respond quite differently to changes in taste and technology parameters depending on whether or not there is rationing in equilibrium

a new approach to decomposition of economic time series into permanent and transitory components with particular attention to measurement of the business cycle abstract this paper introduces a general procedure for decomposition of non stationary time series into a permanent and transitory component allowing both components to be stochastic the permanent component is shown to be a random walk with drift and the transitory or cyclical component is a stationary process with mean zero the decomposition methodology which depends only on past data and therefore is computable in real time is applied to the problem of measuring and dating business cycles in the portwar u s economy we find that measured expansions and contractions are of roughly equivalent duration and that our dating of cyclical episodes tends to lead the traditional nber dating and to a lesser extent the growth cycle chronology of zarnowitz and boschan 1977

is political popularity a random walk this paper tets for nonstationarity in the political popularity of uk parties and governments within the context of an economic model which predicts that party support is an arima 0 1 1 process the hypothesis is rejected for the government s popularity but the results for individual party support are less clear out

the permanent effects of innovation on financial depth abstract this paper examines links between innovation in the us intermediating sector and financial deepening from 1872 1929 technical progress is modeled in a credit rationing framework with limited liability as an enhanced ability of intermediaries to monitor loan recipients this allows an innovating lender to earn temporary rents by lowering loan rates and inducing firms with higher repayment prospects to apply rents persist until others adopt the improvement and competition for loanable funds raises the deposit rate subsequent deposits ensure that more funds are channeled to projects of higher average quality the link between the loan deposit spread and financial deepening implied by the model is then examined in an unobservable components framework the finding that permanent reductions of 1 in the spread of new york banks are associated with increases in financial depth that range from 1 7 to nearly 4 is consistent with a role for efficiency improvements in the rapid financial deepening that characterized the pre 1930 us economy

detrending and business cycle facts a user s guide this note argues that it is hardly the case that the profession is fully aware that the application of di erent filters to the data leads to di erent outcomes and that we have enough evidence to claim that these di erences are unimportant to evaluate the fit models to the data 1998 elsevier science b v all rights reserved jel classification b41 e32

multivariate estimates of the permanent components of gnp and stock prices the economic assumption that a present value relation holds between consumption and income and between stock prices and dividends or the statistical assumption that the consumption income ratio and the dividend price ratio are stationary imply that the permanent or random walk component in each series of a pair must be the same as the permanent component in the other series of a pair either assumption then allows us to estimate the variance of the permanent component of one series gnp stock prices from the variance of the permanent component of the other consumption dividends or from the covariance of the two series permanent components this paper presents such estimates and finds that the permanent components are about half those estimated by similar univariate methods a series of recent papers has examined the importance of a potential unit root to the behavior of real gnp campbell and mankiw 1986 1987 cochrane 1986 clark 1987 and stock prices fama and french 1986 lo and mai if by 0 the series is stationary the response can be any real number which is the innovation in these estimates instead of forcing us to ask the dichotomous question is there a unit root or not they allow us to continuously measure the importance of a potential unit root the actual estimating technique used in these papers varied somewhat cochrane poterba and summers and lo and mai if a series is stationary the variance of k differences will tend to a precursor to this paper appeared under the title spectral density estimates of unit roots we thank masanao aoki lam hansen masao ogaki and chris sims for helpful suggestions the computer programs and data used in this paper are available on request from the authors

effort wages and the international division of labor this paper embeds variable effort into a traditional two sector heckscher ohlin model of international competition effort enters a production function as total factor productivity and on the assumption that effort does not affect capital depreciation the capital cost savings from high effort operations are passed on to workers the labor market thus offers a set of contracts with higher wages compensating for higher effort this has implications for growth openness minimum wages collective bargaining public support of education efficiency of state enterprises the distribution of wealth childbearing and much more

financial intermediation and economic performance historical evidence from five industrialized countries this paper examines the nature of links between the intensity of financial intermediation and economic performance that operated in the united states the united kingdom canada norway and sweden over the 1870 1929 period after describing the coevolution of the financial and real sectors in these countries vector error correction models vecms establish the quantitative importance of long run relationships among measures of financial intensity and real per capita levels of output and the monetary base granger causality tests then suggest a leading role for the intermediation variables in real sector activity while feedback effects are largely insignificant the results suggest an important role for intermediation in the rapid industrial transformations of all five countries

cyclical fluctuations in strike durations canadian data on strikes between 1946 and 1983 are used to estimate linear regression models for the logarithm of completed duration a thorough investigation of the influence of the business cycle reveals strong support for the hypothesis that strike durations are countercyclical the cyclical effect is shown to be robust to both the choice of cyclical variable and the econometric specification and the magnitude of the effect is quite substantial experimentation with different representations of the cycle reveals that it is difficult to improve on a simple formulation involving a single continuous variable

reliability and economic evaluation of power system with renewables a review abstract the share of renewable energy generation has been increasing as a result of the world wide concern on environmental deterioration and climate change associated with burning fossil fuel due to the stochastic and intermittent characteristics of renewable energy resources assessing the reliability of power systems with renewables has become challengeable and been widely studied for the past several decades this paper provides a review of the studies on the reliability and economic evaluation of power system with renewables it starts from a summary of the key indicators and models for assessing the reliability and economics of power systems different studies are then compared in terms of type of renewables evaluation method application area level of study and country involved through which the main features of past studies are identified we also discuss the relationship between economics and reliability that shows the necessity of evaluating reliability and economics of power system with renewables simultaneously a case study is finally proposed to illustrate the differences between alternative system settings in reliability and economic evaluation it is found that the types and scales of renewable energy generation have significant impacts on system reliability and economics which needs to be taken into account in the development of renewable energy power systems

the term structure of currency carry trade risk premia we nd that average returns to currency carry trades decrease signicantly as the maturity of the foreign bonds increases because investment currencies tend to have small local bond term premia the downward term structure of carry trade risk premia is informative about the temporal nature of risks that investors face in currency markets we show that long maturity currency risk premia only depend on the domestic and foreign permanent components of the pricing kernels since transitory currency risk is automatically hedged by interest rate risk for long maturity bonds our

a simulation model for reliability based appraisal of an energy policy the case of lebanon abstract the lebanese electric power system leps has been suffering from technical and financial deficiencies for decades and mirrors the problems encountered in many developing countries suffering from inadequate or no power systems planning resulting in incomplete and ill operating infrastructure and suffering from effects of political instability huge debts unavailability of financing desired projects and inefficiency in operation the upgrade and development of the system necessitate the adoption of a comprehensive energy policy that introduces solutions to a diversity of problems addressing the technical financial administrative and governance aspects of the system in this paper an energy policy for lebanon is proposed and evaluated based on integration between energy modeling and financial modeling the paper utilizes the load modification technique lmt as a probabilistic tool to assess the impact of policy implementation on energy production overall cost technical commercial losses and reliability scenarios reflecting implementation of policy projects are assessed and their impacts are compared with business as usual scenarios which assume no new investment is to take place in the sector conclusions are drawn on the usefulness of the proposed evaluation methodology and the effectiveness of the adopted energy policy for lebanon and other developing countries suffering from similar power system problems

energy status in lebanon and electricity generation reform plan based on cost and pollution optimization abstract this paper presents a review of the energy status conventional and renewable in lebanon and illustrates their problems with the suggested recommendations in addition a detailed review of the principal directorates of the electricity of lebanon company edl is also presented all along with the existing problems and recommended solutions an economic environmental optimization of different power sources is studied where three scenarios are introduced based on the fuel source of different ccgt power plants the results emphasized on the maximum possible use of wind energy and natural gas in electricity generation based on the optimization study a five year master plan for electricity generation is modeled the suggested plan has an investment capital cost of 5553 m with the savings and additional incomes being 5900 m compared to edl financial status in the adopted base year 2009 in addition this plan exceeds the trend to introduce a 12 share of renewable energy in the power sector by 2020 where the share is supposed to be about 15 out of the total installed capacity before this date the concluding remarks highlight the role of politics in the development of the energy sector

a measure of the u s output gap abstract an autoregressive distributed lag regression of the unemployment rate on output growth is structurally stable over the 1890 1986 period inverting this equation yields a measure of the output gap which is not subject to the spurious detrending problem

financial intermediation and delegated monitoring this paper develops a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders it presents a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary diversification within an intermediary serves to reduce these costs even in a risk neutral economy the paper presents some more general analysis of the effect of diversification on resolving incentive problems in the environment assumed in the model debt contracts with costly bankruptcy are shown to be optimal the analysis has implications for the portfolio structure and capital structure of intermediaries

the dawn of an age of deposits in the united states abstract individual deposits in the united states grew from 5 to 23 of gdp between 1863 and 1913 a comprehensive database shows bank entry underlying this trend while historical events including the national banking acts resumption in 1879 and the election of 1896 influenced deposits at the bank level the nation s embrace of deposits was thus driven by stability of the monetary system and confidence in the safety and utility of established and well capitalized banks bank level and county level regressions confirm these patterns for national banks over the entire postbellum period and for a sample of midwest state and national banks from 1888

equity markets and growth cross country evidence on timing and outcomes 1980 1995 abstract the rapid expansion of organized equity exchanges in both emerging and developed markets has prompted policymakers to raise important questions about their macroeconomic impact yet the need to focus on recent data poses implementation difficulties for econometric studies of dynamic interactions between stock markets and economic performance in individual countries this paper overcomes some of these difficulties by applying recent developments in the analysis of panels with a small time dimension to estimate vector autoregressions for a set of 47 countries with annual data for 1980 1995 after describing recent theories on the role of stock markets in growth and considering a pure cross sectional empirical approach our panel vars show leading roles for stock market liquidity and the intensity of activity in traditional financial intermediaries on per capita output the findings underscore the potential gains associated with developing deep and liquid financial markets in an increasingly global economy

financial development growth and the distribution of income a paradigm is presented in which both the extent of financial intermediation and the rate of economic growth are endogenously determined financial intermediation promotes growth because it allows a higher rate of return to be earned on capital and growth in turn provides the means to implement costly financial structures thus financial intermediation and economic growth are inextricably linked in accord with the goldsmith mckinnon shaw view on economic development the model also generates a development cycle reminiscent of the kuznet hypothesis in particular in the transition from a primitive slow growing economy to a developed fast growing one a nation passes through a stage in which the distribution of wealth across the rich and poor widens

finance and inequality the case of india although theory emphasizes the role of financial market frictions in explaining income inequality there is little empirical research exploring how financial development and financial sector reforms influence the evolution of income inequality this article examines how finance impacts income inequality in india using annual time series data for over half a century the results indicate that while financial development helps reduce income inequality financial liberalization seems to exacerbate it the results are robust to the use of different measures for financial development and financial liberalization although the relationship between financial development and economic growth has been extensively studied in the literature see for example king and levine 1993 demetriades and hussein 1996 arestis and demetriades 1997 levine loayza and beck 2000 bell and rousseau 2001 ang and mckibbin 2007 little is known about how finance impacts income inequality the importance of the finance inequality relationship has recently been highlighted in an insightful survey article by claessens and perotti 2007 they indicate that while financial development can help reduce income inequality financial liberalization captured by established interests may do the opposite the theoretical predictions of the effects of finance on income inequality are controversial rajan and zingales 2003b argue that improvements in the formal financial sector primarily benefit the rich greenwood and jovanovic 1990 predict a nonlinear relationship between financial development and income inequality where it is hypothesized that income inequality first increases with the degree of sophistication in the financial systems then stabilizes and eventually declines others propose that the presence of financial market imperfections deters the poor from borrowing adequately to invest in human and physical capital implying that financial development helps alleviate income inequality banerjee and newman 1993 galor and zeira 1993 aghion and bolton 1997 mookherjee and ray 2003 2006 given that theories provide ambiguous predictions regarding the effects of finance on the distribution of income it is useful to approach the issue at the empirical level this could facilitate our understanding of the relationship between finance and inequality and help us to assess the validity of each theoretical model despite the important role of financial market frictions in the theories of poverty and income inequality researchers so far have not adequately addressed whether financial

money output and inflation in the longer term major industrial countries 1880 2001 i introduction the empirical role of money growth in the macroeconomy has been studied by many researchers using different data and methods the most prominent studies focusing on the quantity theory of money are those of friedman and schwartz 1963 1982 using data averaged over the phases of the business cycle in order to capture longer run movements with u s and u k data back to 1867 the study by mccandless and weber 2001 is a representative example for a different approach for 110 countries in the post wwii period longer run growth rates are approximated by growth of a variable over a 30 year period average growth rates 1 the problem with phase averaging is that it does not deal with possible nonstationarity of the data 2 the problem with growth averages over long periods while informative to a degree is that they have limitations too it is impossible to assess the timing of movements in these variables 3 in the frequency domain the long run is associated with frequency zero which in our terminology is the long run trend previous studies in the frequency domain on the long run neutrality of money at zero frequency include the studies of lucas 1980 and geweke 1986 the theory of spectral analysis provides a rigorous framework for extracting specific frequency bands from the data instead of considering only frequency zero stock and watson 1998 applied the band pass filter of baxter and king 1999 to extract cycles frequency bands for u s data and focused on the business cycle and on mostly the post wwii period christiano and fitzgerald 2003 proposed an improved band pass filter and provided an application to the longer run relation of money and inflation for bands of 8 20 years and 20 40 years in the united states from 1900 to 1997 4 the usefulness of monetary aggregates for conducting monetary policy has been seriously called into question because of the instability of money demand a prominent empirical study is that of estrella and mishkin 1997 recent mainstream new keynesian models have no explicit role for money woodford 2008 a contrasting view is that the longer term role of money is still of relevance for monetary policy the european central bank explicitly emphasizes a supporting role that monetary aggregates should play in order to provide an anchor for inflation expectations hafer haslag and jones 2007 issing 2006 king 2002 nelson 2003 christiano motto and rostagno 2007 provided a theoretical new keynesian model where inflation expectations lose their anchor unless money is monitored and reacted to also beck and wieland 2008 presented a new keynesian model where cross checking with money growth movements improves inflation control similarly assenmacher wesche and gerlach 2006 2007 found a significant role for a low frequency low pass filtered component of money in the empirical new keynesian phillips curve equation 5 in the spirit of friedman 1961 we use long time spans so that our results are unlikely to be because of a specific policy rule in place in a given period we have 122 years of annual data from 1880 to 2001 before the introduction of the euro in 2002 we have real gross domestic product gdp money and consumer price indices cpis with no gaps for 11 industrialized countries 6 the countries included in our study differ in such terms as their institutions fiscal and monetary policies and economic growth rates nonetheless at least in peace time they were similar in generally having comparatively free markets in which prices and interest rates were determined our aim is to apply analytic methods that are free from economic and statistical models as much as possible in order to explore empirical regularities or stylized facts in the data also the focus of our research is the longer run we employ band pass filters to pick out cycles from each time series that last 8 40 years that is the longer term component

post independence india a case of finance led industrialization abstract this paper examines whether financial intermediaries have played a leading role in influencing india s economic performance after describing the evolution and functions of the financial sector we construct a set of vector autoregressive var and vector error correction models vecm to evaluate the strength and direction of the links between measures of formal intermediation and various economic aggregates the results suggest that i the financial sector was instrumental in promoting aggregate investment and output but also in the steady shift toward industry that has characterized india s development ii the operative channel was one of debt accumulation rather than improvements in total factor productivity and iii its contributions went beyond the passive support of fiscal policy

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

interaction between economic and financial development this paper presents a model of financial and economic development which assumes the consumption of real resources by the financial sector financial development occurs endogenously as the economy reaches a critical threshold of economic development compared to financial autarky financial intermediaries allocate savings net of their costs of operation to more productive investments whenever the technology financed by intermediaries is more capital intensive than that operated in financial autarky the growth effect of financial development is ambiguous as a result financial development may be unsustainable however when financial development is sustainable the credit market becomes more competitive and more efficient over time and this could eventually contribute to economic growth nonetheless given monopolistic competition in the financial sector the level of entry into the credit market is generally inefficient for instance with diminishing returns to specialisation entrants might be too few at the early stages of economic development and too many later on

infrastructure finance and industrial takeoff in england that financial matters did not constrain industrial takeoff in the uk is generally accepted in the historical literature in contrast contemporary empirical analyses have found evidence that financial development can be a causal determinant of economic growth we look to reconcile these findings by concentrating on a particular aspect of industrializing uk where inefficiencies in finance could have had bite the finance of physical infrastructures we document the historical record and develop the importance of spatial disaggregation and spillovers in both technological and financial development we develop a simple model that captures the nature of infrastructure finance within a theory of endogenous growth where financial costs are endogenous we argue that the conception of the finance growth nexus as a largely static aggregative phenomenon misses out a good deal of complexity and we relate that complexity to a number of implications for regulation of both financial systems and the emergence of infrastructures

integrated resource planning irp and power sector reform in developing countries abstract the integrated resource planning irp approach is one that considers both supply and demand side options to meet the need for a resource while minimising the costs accruing to the firm and to society this paper focuses on irp as a tool for the power sector in the light of the existing problems and the ongoing reforms in developing countries it looks at the advantages that irp would afford juxtaposing these with the barriers to such a planning process those encountered in the past as well as the possibilities in view of structural changes it then discusses the policies that would enable the irp approach to be usefully employed to mitigate the problems of the power sector although irp has receded in importance in some areas of the world there are perceptible benefits for developing countries these could adopt such planning methods through the agents and the instruments suggested

time series decomposition and measurement of business cycles trends and growth cycles abstract a study of business cycles does not require trend estimation and elimination but a study of growth cycles does major cyclical slowdowns and speedups deserve to be analyzed but the needed time series decomposition presents difficult problems mainly because trends and cycles influence each other we compare cyclical movements in levels deviations from trend and smoothed growth rates for both the quarterly real gdp and the monthly u s coincident index using the phase average trend pat then we compare alternative trend estimates deterministic and stochastic linear and nonlinear and the corresponding series of deviations from these trends we discuss how the resulting estimates differ for u s growth cycles in the post world war ii period the results of pat show great similarity to the results obtained with the hodrick prescott local linear trend band pass filtering methods

a model of trade in exhaustible resources what distinguishes exhaustible resources from most other goods is not only their non renewable nature but also a combination of two other important characteristics related to their economic functions in their role as an input resources serve as an esseptial factor in the production of final goods moreover because their usefulness remains intact until they are consumed in the process of production they may also serve as a store of value in the absence of other types of marketable assets this latter characteristic enables the owner of the resource to achieve through optimal resource management his desired time profile of consumption corresponding to these two economic functions are two possible motives for international trade in exhaustible resources first in connection with their role as a productive input trade in resources promotes efficiency in the allocation of factors of production throughout the world economy on the basis of this motive for trade countries with a relatively high per capita endowment of the resource should be expected to export the resource in exchange for final goods second in connection with their asset function trade in resources may be viewed as a means of achieving efficiency in the intertemporal allocation of consumption goods among countries economies with a relatively high rate of time preference desire a relatively high ratio of current to future consumption accordingly impatient countries might be expected to import consumption goods in exchange for the resource in the present and export consumption goods in the future the interaction between these two motives for trade is examined in the present paper within a simple two period two country model traded objects are assumed to be an exhaustible resource and a single consumption good although the possibility of trade in consumption loans is also considered later in the paper the consumption good is produced in both countries with the aid of labor and the resource because the latter has the dual role of being a productive input as well as a store of value in the model international trade is viewed both as a means of reallocating the world s endowment of the resource so as to ensure

analysis of us real gnp and unemployment interactions abstract instead of the more common unemployment rate the time series data of the level of us unemployment is used together with us real gnp and later also with the us money stock to identify a bivariate and trivariate structural model the model is then used to examine the interaction of the unemployment level with the real gnp in the business cycle frequencies the commonly perceived okun s law is shown to disappear in the trivariate model

the prebisch singer hypothesis a reappraisal independent of stationarity hypotheses time series behaviour of the relative price of primary commodities raul prebisch i950 and hans singer i950 believed that the long term trend of primary commodity prices was negative the latter in an interesting discussion of the above quandary pp 482 3 viewed rises in primary commodity prices as purely temporary sources of surplus that offered short lived opportunities to increase industrial investment these opportunities were missed by private investors who instead increased primary sector investment in such circumstances because all private activity tends to be governed by the price

estimating long run economic equilibria with stochastic trends an asymptotic theory is provided to analyze a menu of currently existing estimators of cointegrated systems we study in detail the single equation ecm seecm approach of hendry our theoretical results lead to prescriptions for empirical work such as specifying seecm s nonlinearly and including lagged equilibrium relationships rather than lagged differences of the dependent variable as covariates simulations support these prescriptions and point to problems of overfitting not encountered in the semiparametric approach of phillips and hansen 1990
