energy consumption and economic growth relationship evidence from panel data for low and middle income countries abstract this paper uses the panel data of energy consumption ec and economic growth gdp for 51 countries from 1971 to 2005 these countries are divided into three groups low income group lower middle income group and upper middle income group countries firstly a relationship between energy consumption and economic growth is investigated by employing pedroni 1999 panel cointegration method secondly panel causality test is applied to investigate the way of causality between the energy consumption and economic growth finally we test whether there is a strong or weak relationship between these variables by using pedroni 2001 method the empirical results of this study are as follows i energy consumption and gdp are cointegrated for all three income group countries ii the panel causality test results reveal that there is long run granger causality running from gdp to ec for low income countries and there is bidirectional causality between ec and gdp for middle income countries iii the estimated cointegration factor is not close to 1 in other words no strong relation is found between energy consumption and economic growth for all income groups considered in this study the findings of this study have important policy implications and it shows that this issue still deserves further attention in future research

the nature of diversified business groups a research design and two case studies diversified business groups dominate the private sectors of most of the world s economies several of these economies have undergone sudden policy changes that significantly increase domestic competitive intensity the authors demonstrate how the changes in corporate scope that accompany such competitive shocks can be used to weigh the importance of different explanations for the existence of diversified business groups the authors illustrate their reasoning by studying the restructuring of two of india s largest business groups following a comprehensive post 1991 package of policy reforms the case studies also elucidate aspects of the restructuring process that should inform larger sample empirical analyses copyright 1998 by blackwell publishing ltd

business groups entry barrier innovation debate revisited abstract we argue that in the presence of market imperfections business groups market share in a sector acts as a proxy for barriers to enter that sector recognition of group share as a proxy for entry barriers allows us to revisit the entry barrier innovation debate in the context of emerging economies evidence presented in this paper note innovative performance is at its peak when groups market share is at an intermediate level suggesting that either too many or too few entry barriers could be harmful for innovation this result appears robust across a variety of non parametric and parametric regression techniques

the out of sample success of term structure models as exchange rate predictors a step beyond abstract a large literature suggests that standard exchange rate models cannot outperform a random walk forecast and that the forward rate is not an optimal predictor of the spot rate however there is evidence that the term structure of forward premia contains valuable information for forecasting future spot exchange rates and that exchange rate dynamics display nonlinearities this paper proposes a term structure forecasting model of exchange rates based on a regime switching vector equilibrium correction model which is novel in this context our model significantly outperforms both a random walk and to a lesser extent a linear term structure vector equilibrium correction model for four major dollar rates across a range of horizons

energy taxes and endogenous technological change abstract this paper studies the effects of a tax on energy use in a growth model where market structure is endogenous and jointly determined with the rate of technological change because this economy does not exhibit the scale effect a positive relation between tfp growth and aggregate r d the tax has no effect on the steady state growth rate it has however important transitional effects that give rise to surprising results specifically under the plausible assumption that energy demand is inelastic there may exist a hump shaped relation between the energy tax and welfare this shape stems from the fact that the reallocation of resources from energy production to manufacturing triggers a temporary acceleration of tfp growth that generates a shaped time profile of consumption if endogenous technological change raises consumption sufficiently fast and by a sufficient amount in the long run and households are sufficiently patient the tax raises welfare despite the fact that in line with standard intuition it lowers consumption in the short run

two faces effects of business groups on innovation in emerging economies this paper shows that business groups in emerging economies exert dual effects on innovation while groups facilitate innovation by providing institutional infrastructure groups also discourage innovation by creating entry barriers for nongroup firms and thereby inhibit the proliferation of new ideas this pattern reflects an evolutionary process in which the interplay of the availability of innovation infrastructure and variety of ideas influences the level of innovation in an industry we show that group market share has an inverted u impact on innovation in industrial sectors of both korea and taiwan during the 1981 1995 period institutional differences between korea and taiwan in terms of market structure and industrial policies lead to different innovation thresholds the point at which the marginal costs of increasing group share begin to dominate the marginal benefits in the two countries

energy consumption and economic growth new insights into the cointegration relationship abstract this paper examines the long run relationship between energy consumption and real gdp including energy prices for 25 oecd countries from 1981 to 2007 the distinction between common factors and idiosyncratic components using principal component analysis allows to distinguish between developments on an international and a national level as drivers of the long run relationship indeed cointegration between the common components of the underlying variables indicates that international developments dominate the long run relationship between energy consumption and real gdp furthermore the results suggest that energy consumption is price inelastic causality tests indicate the presence of a bi directional causal relationship between energy consumption and economic growth

energy consumption synchronization between europe united states and japan a spectral analysis assessment abstract this paper aims to advance a model able to explain the synchronization tendency in energy consumption under the impact of international technology transfers the key argument is related to the differences in energy consumption efficiency of local and foreign technologies one direct testable consequence of the model is that there might be a certain correlation between the energy consumption between countries and or economic areas where a free movement of capital goods and technologies takes place hence it is further tested in the framework of a multivariate spectrum analysis the case of energy consumption synchronization between europe and respectively united states and japan for a time span between 1981 and 2011 based on the data provided by u s energy information administration there are evidences of a leading behavior of energy consumption in united states and japan in respect to europe as well as of short run phase delays of 2 up to 5 months

trade finance specialization and synchronization i investigate the determinants of business cycle synchronization across regions the linkages between trade in goods financial openness specialization and business cycle synchronization are evaluated in the context of a system of simultaneous equations the main results are as follows i specialization patterns have a sizable effect on business cycles most of this effect is independent of trade or financial policy but directly reflects differences in gdp per capita ii a variety of measures of financial integration suggest that economic regions with strong financial links are significantly more synchronized even though they also tend to be more specialized iii the estimated role of trade is closer to that implied by existing models once intra industry trade is held constant the results obtain in a variety of data sets measurement strategies and specifications they relate to a recent strand of international business cycle models with incomplete markets and transport costs and on the empir

a joint model for the term structure of interest rates and the macroeconomy we present and estimate a continuous time term structure model that incorporates observable macroeconomic variables and latent variables with a clear macroeconomic interpretation our model is able to accurately describe the joint dynamics for us macroeconomic variables and the yield curve however the observable variables do not explain the long end of the term structure central tendencies of these macroeconomic variables do a much better job in this respect these unobservable factors also play an important role in the description of the interest rate policy rule both observable and non observable factors determine the risk premia and hence bond excess holding returns copyright 2006 john wiley sons ltd

currency premia and global imbalances we show that a global imbalance risk factor that captures the spread in countries external imbalances and their propensity to issue external liabilities in foreign currency explains the cross sectional variation in currency excess returns the economic intuition is simple net debtor countries offer a currency risk premium to compensate investors willing to finance negative external imbalances because their currencies depreciate in bad times this mechanism is consistent with exchange rate theory based on capital flows in imperfect financial markets we also find that the global imbalance factor is priced in cross sections of other major asset markets

electricity consumption and economic growth nexus in portugal using cointegration and causality approaches the aim of this paper is to re examine the relationship between electricity consumption economic growth and employment in portugal using the cointegration and granger causality frameworks this study covers the sample period from 1971 to 2009 we examine the presence of a long run equilibrium relationship using the bounds testing approach to cointegration within the unrestricted error correction model uecm moreover we examine the direction of causality between electricity consumption economic growth and employment in portugal using the granger causality test within the vector error correction model vecm as a summary of the empirical findings we find that electricity consumption economic growth and employment in portugal are cointegrated and there is bi directional granger causality between the three variables in the long run with the exception of the granger causality between electricity consumption and economic growth the rest of the variables are also bi directional granger causality in the short run furthermore we find that there is unidirectional granger causality running from economic growth to electricity consumption but no evidence of reversal causality

new keynesian macroeconomics and the term structure this article complements the structural new keynesian macro framework with a no arbitrage affine term structure model whereas our methodology is general we focus on an extended macro model with an unobservable time varying inflation target and the natural rate of output which are filtered from macro and term structure data we obtain large and significant estimates of the phillips curve and real interest rate response parameters our model also delivers strong contemporaneous responses of the entire term structure to various macroeconomic shocks the inflation target dominates the variation in the level factor whereas the monetary policy shocks dominate the variation in the slope and curvature factors

economic development and the demand for energy a historical perspective on the next 20 years abstract this paper draws on evidence from the last two centuries of industrialisation analysing the evolution of energy intensity over the long and short run we argue that the increased specialisation of the fuel mix coupled with accelerating convergence of both the sectoral and technological composition of economies will continue to improve energy intensity of economic output and to reduce the reliance on any single energy resource this analysis suggests that even high growth in per capita income over the next 20 years need not be constrained by resource availability

r d and internal finance a panel study of small firms in high tech industries since joseph schumpeter economists have argued that internal finance should be an important determinant of r d expenditures yet almost without exception previous empirical studies have not found evidence of such a relation using newly available data the authors investigate this puzzle with a panel of 179 small firms in high tech industries under each estimation strategy they employ the authors find an economically large and statistically significant relationship between r d investment and internal finance their results are consistent with the view that because of capital market imperfections the flow of internal finance is the principal determinant of the rate at which small high tech firms acquire technology through r d copyright 1994 by mit press

the propensity to patent abstract this paper analyzes the relationship between 1974 rd among the exceptions the tendency was toward diminishing returns variables measuring overseas sales federal r d support diversification scope of invention use and invention type had only modest explanatory power there was no significant evidence of disproportionate patent accumulation in the more highly concentrated industries

the predictive power of the term structure of interest rates in europe and the united states implications for the european central bank abstract this paper examines the relationship of the term structure of interest rates to monetary policy instruments and to subsequent real activity and inflation in both europe and the united states the results show that monetary policy is an important determinant of the term structure spread but is unlikely to be the only determinant in addition there is significant predictive power for both real activity and inflation the yield curve is thus a simple and accurate measure that should be viewed as one piece of useful information which along with other information can be used to help guide european monetary policy

evaluating an alternative risk preference in affine term structure models dai and singleton 2002 and duffee 2002 show that there is a tension in affine term structure models between matching the mean and the volatility of interest rates this article examines whether this tension can be solved by an alternative parametrization of the price of risk the empirical evidence suggests that first the examined parametrization is not sufficient to solve the mean volatility tension second the usual result in the estimation of affine models indicating that some of the state variables are extremely persistent may have been caused by the lack of flexibility in the parametrization of the price of risk term structure models have several uses including pricing fixed income derivatives managing the risk of fixed income portfolios and detecting relationships between the term structure of interest rates and macrovariables such as inflation and consumption to perform well in these tasks term structure models must be numerically and econometrically tractable while matching the empirical properties of the term structure movements at least two empirical properties of the term structure of interest rates have been well established by financial economists over the years see dai and singleton 2003 for a survey first the term premium or the expected excess return of treasury bonds has a high time variability second the volatility of interest rates is time varying these two properties are so prominent in the data that they will be referred to as stylized facts while these two stylized facts are very well established in the empirical literature affine term structure models are thoroughly discussed in the theoretical literature affine models are those in which the yield of zero coupon bonds are affine functions of the model state variables classic

futures prices as risk adjusted forecasts of monetary policy many researchers have used federal funds futures rates as measures of financial markets expectations of future monetary policy however to the extent that federal funds futures reflect risk premia these measures require some adjustment in this paper we document that excess returns on federal funds futures have been positive on average and strongly countercyclical in particular excess returns are surprisingly well predicted by macroeconomic indicators such as employment growth and financial business cycle indicators such as treasury yield spreads and corporate bond spreads excess returns on eurodollar futures display similar patterns we document that simply ignoring these risk premia significantly biases forecasts of the future path of monetary policy we also show that risk premia matter for some futures based measures of monetary policy shocks used in the literature

the new econometrics of structural change dating breaks in u s labor productivity we have seen the emergence of three major innovations in the econometrics of structural change in the past fifteen years 1 tests for a structural break of unknown timing 2 estimation of the timing of a structural break and 3 tests to distinguish unit roots from broken time trends these three innovations have dramatically altered the face of applied time series econometrics in this paper we review these three innovations and illustrate their application through an empirical assessment of u s labor productivity in the manufacturing durables sector

institutional voids or organizational resilience business groups innovation and market development in latin america summary the paper compares the innovativeness of group affiliated firms gafs and standalone firms safs and it investigates how country specific institutional factors affect the group innovation relationship the paper analyzes the contrasting predictions of two competing views the institutional voids and the organizational resilience theses the empirical analysis focuses on a large sample of firms in latin america in line with the organizational resilience thesis the results point out that the superior innovation performance of gafs is stronger for national economies with more efficient financial legal and labor market institutions

financial globalization and real regionalization over the period 1972 1986 the correlations of gdp employment and investment between the united states and an aggregate of europe canada and japan were respectively 0 76 0 66 and 0 63 for the period 1986 to 2000 the same correlations were much lower 0 26 0 03 and 0 07 real regionalization at the same time u s international asset trade has significantly increased for example between 1972 and 1999 united states gross fdi and equity assets in the same group of countries rose from 4 to 23 percent of the u s capital stock financial globalization we argue that these two trends are intimately related we document that the correlation of real shocks between the u s and the rest of the world has declined we then present a model in which international financial market integration occurs endogenously in response to less correlated shocks financial integration further reduces the international correlations in gdp and factor supplies we find that both less correlated shocks and endogenous financial market development are needed to account for all the changes in the international business cycle

macro factors and the term structure of interest rates this paper presents an essentially affine model of the term structure of interest rates making use of macroeconomic factors and their long run expectations the model extends the approach pioneered by kozicki and tinsley 2001 by modeling consistently long run inflation expectations simultaneously with the term structure application to the u s economy shows the importance of long run inflation expectations in the modeling of long term bond yields the paper also provides a macroeconomic interpretation for the latent factors found in standard finance models of the yield curve the level factor represents the long run inflation expectation of agents the slope factor captures business cycle conditions and the curvature factor expresses a clear independent monetary policy factor

multimarket contact and collusive behavior traditional analyses of industrial behavior typically link the exercise of market power in an industry to internalfeatures such as demand conditions concentration and barriers to entry nevertheless some economists have remained concerned that external factors such as contact across markets may also play a significant role in determining the level of competitiveness in any particular industry in this article we examine the effect of multimarket contact on the degree of cooperation that firms can sustain in settings of repeated competition we isolate conditions under which multimarket contact facilitates collusion and show that these collusive gains are achieved through modes of behavior that have been identified in previous empirical studies of multimarketfirms

how does globalization affect the synchronization of business cycles this paper examines the impact of rising trade and financial integration on international business cycle comovement among a large group of industrial and developing countries the results provide at best limited support for the conventional wisdom that globalization has increased the degree of synchronization of business cycles the evidence that trade and financial integration enhance global spillovers of macroeconomic fluctuations is mostly limited to industrial countries one striking result is that on average cross country consumption correlations have not increased in the 1990s precisely when financial integration would have been expected to result in better risk sharing opportunities especially for developing countries this abstract was borrowed from another version of this item

the yield curve and macroeconomic dynamics we show that microfounded dsge models with nominal rigidities can be successful in replicating features of bond yield data including sizeable term premia and volatile long term yields which have previously been considered puzzling in general equilibrium frameworks at the same time sample moments of consumption growth and inflation can be fit relatively well the improved model performance does not arise directly from the presence of nominal rigidities however this feature introduces short run monetary non neutrality so that monetary policy affects consumption dynamics and bond prices a high degree of interest rate smoothing in the policy rule is essential for our results at the core of dynamic macroeconomic models we find equilibrium relationships which describe the allocation of quantities e g consumption and investment and when imperfect competition prevails the setting of prices these equations are typically valid across time and across states of nature and financial assets form the tool that is supposed to ensure their validity financial assets are therefore an integral part of macroeconomic models any well specified model should be able to match financial data as well as macro data it is therefore problematic that microfounded models have had a hard time explaining key features of asset prices the most famous example of this difficulty is the equity premium puzzle but various features of bond yield data have also been char acterised as puzzling in the literature a number of papers including backus et al 1989 donaldson et al 1990 den haan 1995 and chapman 1997 have con cluded that general equilibrium models cannot generate term premia of a magnitude comparable to what we observe in actual data and may not even be capable of producing positive term premia for equity one could argue that fundamentals the expected future profitability of individual firms are unobservable and difficult to evaluate equity prices may therefore be thought to be subject to fluctuations disconnected from the real economy information acquisition fads etc and one could hope that the inability of macroeconomic models to match equity prices does not represent a signal of misspecification this argument is more difficult to construct for bonds bond yields should ultimately reflect expectations of future monetary policy decisions which at least in recent years are arguably more predictable than equity fundamentals thus the ability of macroeconomic models to explain bond prices represents an important test of their empirical performance in this article we revisit the relationship between bond prices and macroeconomic fundamentals contrary to the papers cited above that rely on flexible price models we

market structure and research intensity in high technological opportunity industries where the cost and uncertainty of r d are high and conditions favor speedy imitation by competitors concentration has a statistically significant and substantial positive impact on research intensity but its impact is clearly negative when r d cost and uncertainty are low and where high barriers to imitation exist a sample of 160 business unit observations for 1978 was drawn from the pims data base all the sample business units industries recently experienced major technological changes research intensity was measured by non government financed r d expenditures as a percentage of sales

exploiting the conditional density in estimating the term structure an application to the cox ingersoll and ross model we propose an empirical method that utilizes the conditional density of the state variables to estimate and test a term structure model with known price formulae using data on both discount and coupon bonds the method is applied to an extension of a two factor model due to cox ingersoll and ross 1985 cir our results show that estimates based on only bills imply unreasonably large price errors for longer maturities we reject the original cir model using a likelihood ratio test and conclude that the extended cir model also fails to provide a good description of the treasury market

the geography of trade and technology shocks in the united states abstract this paper explores the geographic overlap of trade and technology shocks across local labor markets in the united states regional exposure to technological change as measured by specialization in routine task intensive production and clerical occupations is largely uncorrelated with regional exposure to trade competition from china while the impacts of technology are dispersed throughout the united states the impacts of trade tend to be more geographically concentrated owing in part to the spatial agglomeration of labor intensive manufacturing our findings highlight the feasibility of separately identifying the impacts of recent changes in trade and technology on us regional economies

determinants of business cycle comovement a robust analysis abstract this paper investigates the determinants of business cycle comovement between countries our dataset includes over 100 countries both developed and developing we search for variables that are robust in explaining comovement using the approach of leamer amer econom rev 73 1983 31 variables considered are i bilateral trade between countries ii total trade in each country iii sectoral structure iv similarity in export and import baskets v factor endowments and vi gravity variables we find that bilateral trade is robust however two variables that the literature has argued are important for business cycles industrial structure and currency unions are found not to be robust

term structure surprises the predictive content of curvature level and slope summary this paper analyzes the predictive content of the term structure components level slope and curvature within a dynamic factor model of macroeconomic and interest rate data surprise changes of the three components are identified using sign restrictions and their macroeconomic underpinnings are studied via impulse response analysis the curvature factor is found to carry predictive information both about the future evolution of the yield curve and the macroeconomy in particular unexpected increases of the curvature factor precede a flattening of the yield curve and announce a significant decline of output more than 1 year ahead copyright 2010 john wiley sons ltd

from carry trades to curvy trades traditional carry trade strategies are based on differences in short term interest rates neglecting any other information embedded in yield curves we derive return distributions of carry trade portfolios among g10 currencies where the signals to buy and sell currencies are based on summary measures of the yield curve the nelson siegel factors we find that a strategy based on the relative curvature factor the curvy trade yields higher sharpe ratios and a smaller return skewness than traditional carry trade strategies curvy trades build less upon the typical carry currencies like the japanese yen and the swiss franc and are hence less susceptible to crash risk in line with that standard pricing factors of traditional carry trade returns such as exchange rate volatility fail to explain curvy trade returns in a linear asset pricing framework our findings are in line with recent interpretations of the curvature factor a relatively high curvature signals a relatively higher path of future short term rates over the medium term putting upward pressure on the currency

macro factors and the affine term structure of interest rates this paper formulates an affine term structure model of bond yields from a dynamic stochastic general equilibrium model with observable macro state variables as the term structure factors model implications for the joint macro term structure dynamics are consistent with the empirical patterns from the var estimation model calibration and simulation exercises also provide clear macroeconomic interpretations of the latent term structure factors as found in the finance literature most of the slope factor movement can be explained by exogenous monetary policy shocks and the level factor movement is closely related to the technology shocks

shifting endpoints in the term structure of interest rates abstract this paper links the term structure to perceptions of monetary policy long horizon forecasts of short rates required by no arbitrage term structure models are heavily influenced by the endpoints or limiting conditional forecasts of the short rate process common assumptions that the short rate is mean reverting or contains a unit root are shown to generate unrealistic yield predictions failures occur because these assumptions inadequately account for historical shifts in market perceptions of the policy target for inflation this paper links endpoint shifts to agent learning about shifts in long term policy goals shifting endpoints in short rate processes significantly improve yield predictions

energy consumption and growth in south america evidence from a panel error correction model abstract this study examines the relationship between energy consumption and economic growth for a panel of nine south american countries over the period 1980 2005 within a multivariate framework given the relatively short span of the time series data a panel cointegration and error correction model is employed to infer the causal relationship pedroni s heterogeneous panel cointegration test reveals a long run equilibrium relationship between real gdp energy consumption the labor force and real gross fixed capital formation with the respective coefficients positive and statistically significant the granger causality results indicate both short run and long run causality from energy consumption to economic growth which supports the growth hypothesis

term structure evidence on interest rate smoothing and monetary policy inertia abstract numerous studies have used quarterly data to estimate monetary policy rules or reaction functions that appear to exhibit a very slow partial adjustment of the policy interest rate the conventional wisdom asserts that this gradual adjustment reflects a policy inertia or interest rate smoothing behavior by central banks however such quarterly monetary policy inertia would imply a large amount of forecastable variation in interest rates at horizons of more than 3 months which is contradicted by evidence from the term structure of interest rates the illusion of monetary policy inertia evident in the estimated policy rules likely reflects the persistent shocks that central banks face

expectation puzzles time varying risk premia and dynamic models of the term structure abstract linear projections of returns on the slope of the yield curve have contradicted the implications of the traditional expectations theory this paper shows that these findings are not puzzling relative to a large class of richer dynamic term structure models specifically we match all the key empirical findings reported by fama and bliss 1987 american economic review 77 4 680 692 and campbell and shiller 1991 review of economic studies 58 495 514 among others within large subclasses of affine and quadratic gaussian term structure models additionally we show that certain risk premium adjusted projections of changes in yields on the slope of the yield curve recover the coefficients of unity predicted by the models key to this matching are parameterizations of the market prices of risk that let the risk factors affect the market prices of risk directly and not only through factor volatilities the risk premiums have a simple form consistent with fama s findings on the predictability of forward rates and are also shown to be consistent with interest rate feedback rules used by a monetary authority in setting monetary policy

clean air regulation and heterogeneity in us gasoline prices in order to improve public health in areas with air quality problems the us clean air act imposes a variety of federal regulations on gasoline which have led to a proliferation of fuel blends known as boutique fuels more than 45 fuel blends are sold nationwide we examine the effects of this program on wholesale gasoline prices the methodological innovation in this study is the use of a regulatory distance measure as a proxy for measuring market power that arises from product differentiation we find that clean air regulation increases gasoline prices by increasing the cost of refining but more importantly by creating regulatory islands it segments the market and increases the market power of firms our estimation controls for the potential endogeneity of the regulatory variables we find that ols techniques systematically underestimate the effect of regulation on gasoline prices

asset pricing implications of a new keynesian model to match the stylised facts of goods and labour markets the canonical new keynesian model augments the optimising neoclassical growth model with nominal and real rigidities we ask what the implications of this type of model are for asset prices using a second order numerical solution to the model we examine bond and equity returns the equity risk premium and the behaviour of the real and nominal term structure we catalogue the factors that are most important for determining the size of risk premia and the slope and level of the yield curve in a world of technology shocks only increasing the degree of real rigidities raises risk premia and increasing nominal rigidities reduces risk premia in a world of monetary policy shocks only both real and nominal rigidities raise risk premia the results indicate that the implications of the new keynesian model for average asset returns depend critically on the

why has the u s economy become less correlated with the rest of the world in this paper we do two things first we document that over the last 40 years the u s business cycle has become less synchronized with the cycle in the rest of the world second we try to explain why this has happened we use a general equilibrium model as a tool to discriminate between two alternative explanations i a change in the nature of real shocks and ii an increase in u s financial integration with the rest of the world our results indicate that financial integration has played the major role in producing the observed changes in international co movement

firm organization industrial structure and technological innovation abstract the formal and informal structures of firms and their external linkages have an important bearing on the rate and direction of innovation this paper explores the properties of different types of firms with respect to the generation of new technology various archetypes are recognized and an effort is made to match organization structure to the type of innovation the framework is relevant to technology and competition policy as it broadens the framework economists use to identify environments that assist innovation

the yield curve and the macro economy across time and frequencies this paper assesses the relation between the yield curve and the main macroeconomic variables in the u s between early 1960s and 2009 across time and frequencies using wavelet analyses the shape of the yield curve is modelled by latent factors corresponding to its level slope and curvature estimated by maximum likelihood with the kalman filter the macroeconomic variables measure economic activity unemployment inflation and the fed funds rate the cross wavelet tools employed coherency and phase difference the set of variables and the length of the sample allow for a thorough appraisal of the timevariation and structural breaks in the direction intensity synchronization and periodicity of the relation between the yield curve and the macro economy our evidence establishes a number of new stylized facts on the yield curve macro relation and sheds light on several results found in the literature which could not have been achieved with analyses conducted strictly in the time domain as most of the literature or purely in the frequency domain

the impact of technological innovation on international trade patterns the evidence reconsidered abstract this paper presents some new evidence in relation to the role of technical change in particular industrial innovation on the international competitiveness of the various oecd countries its originality consists primarily of a using a technology output indicator to measure technological performance b presenting and comparing various measures of trade and technological performance for each individual oecd country with the exception of iceland c analysing at a relatively high level of product industry disaggregation the relationship between export performance and technological performance at the same time the very limited scope of the paper has to be emphasized a the analysis is purely static all the evidence presented relates to one year 1977 b most of the results obtained are preliminary and should be further substantiated by more detailed empirical and theoretical research c as a consequence little attention has been paid to policy implications which it was felt could only be discussed properly in a later stage the paper consists of four sections a brief review of the state of the art section 1 a discussion on definitions of technology intensity section 2 the development of the best technology output indicator section 3 and the empirical analysis itself section 4 the following most important results emerge from these various sections a there are serious shortcomings in using average technology intensity as bench mark for classifying products or industries in technology intensive or nontechnology intensive categories b there is a substantial difference between technology intensity as measured on the basis of a technology input proxy rd c yet as between countries the most traditional output and input indicators the number of patents granted and the amount spent on rd d foreign patenting in particular foreign patenting in the united states figs 1 and 2 section 3 is a more reliable technology output proxy than domestic patenting e in terms of technological comparative advantage as opposed to technology intensity it is the small oecd countries as opposed to the large ones which seem to base their trade comparative advantage on technological comparative performance table 7 section 4 1 f at the individual industry level it is found that i for most technology intensive industries defined however in a less restrictive way than us r d intensities a close relation exists between technological performance and export performance and ii that as compared to other country specific resource variables technological performance is the most important trade explanatory variable its elasticity increasing with the technology intensity of industries tables 11 and 12 section 4 2 space constraints prevented us from presenting the data in relation to the inter industry and inter country analysis these can however be obtained from the author

examining the bond premium puzzle with a dsge model the basic inability of standard theoretical models to generate a sufficiently large and variable nominal bond risk premium has been termed the bond premium puzzle we show that the term premium on long term bonds in the canonical dynamic stochastic general equilibrium dsge model used in macroeconomics is far too small and stable relative to the data we find that introducing long memory habits in consumption as well as labor market frictions can help fit the term premium but only by seriously distorting the dsge model s ability to fit other macroeconomic variables such as the real wage therefore the bond premium puzzle remains

the role of globalization on the recent evolution of energy demand in india implications for sustainable development using annual data for the period 1971 2012 this study explores the relationship between globalization and energy consumption for india by endogenizing economic growth financial development and urbanization the cointegration test proposed by bayer hanck 2013 is applied to estimate the long run and short run relationships among the variables after confirming the existence of cointegration the overall results from the estimation of an ardl energy demand function reveal that in the long run the acceleration of globalization measured in three dimensions economic social and overall globalization leads to a decline in energy demand in india furthermore while financial development is negatively related to energy consumption economic growth and urbanization are the key factors leading to increased energy demand in the long run these results have policy implications for the sustainable development of india in particular globalization and financial development provide a win win situation for india to increase its economic growth in the long run and become more environmentally sustainable

what does the term structure tell us about future inflation abstract this empirical analysis indicates that for maturities of six months or less the term structure of nominal interest rates provides almost no information about the future path of inflation but does provide information about the term structure of real interest rates however as maturities lengthen to nine and twelve months the nominal term structure begins to contain information about future inflation but ceases to provide information about the real term structure these results are explained by differences in the relative variability of expected future inflation changes and real term structure slopes at different points in the term structure

energy consumption and income a semiparametric panel data analysis this paper proposes a semiparametric analysis for the study of the relationship between energy consumption per capita and income per capita for an international panel dataset it shows little evidence for the existence of an environmental kuznets curve for energy consumption energy consumption increases with income for a majority of countries and then stabilizes for very high income countries neither changes in energy structure nor macroeconomic cycle technological change have significant effect on energy consumption

good carry bad carry we distinguish between good and bad carry trades constructed from group of ten g 10 currencies the good trades exhibit higher sharpe ratios and sometimes positive return skewness in contrast to the bad trades which have both substantially lower sharpe ratios and highly negative return skewness surprisingly good trades do not involve the most typical carry currencies like the australian dollar and japanese yen the distinction between good and bad carry trades significantly alters our understanding of currency carry trade returns and invalidates for example explanations invoking return skewness and crash risk

empirical exchange rate models and currency risk some evidence from density forecasts a large literature in exchange rate economics has investigated the forecasting performance of empirical exchange rate models using conventional point forecast accuracy criteria however in the context of managing exchange rate risk interest centers on more than just point forecasts this paper provides a formal evaluation of recent exchange rate models based on the term structure of forward exchange rates which previous research has shown to be satisfactory in point forecasting in terms of density forecasting performance the economic value of the exchange rate density forecasts is investigated in the context of an application to a simple risk management exercise

explorations into factors explaining money market returns in this article we measure and interpret the common factors that describe money market returns results are presented for both three and four factor models we find that the three factor model explains on average 86 percent of the total variation in most money market returns while the four factor model explains on average 90 percent of this variation using mimicking portfolios we provide an interpretation of the systematic risks represented by these factors in this article we attempt to measure and interpret the common factors that describe money market returns the factor approach we employ assumes that the covariance matrix of a set of random variables in this case excess returns can be decomposed into common or systematic components and idiosyncratic or nonsystematic components this decomposition into systematic and nonsystematic components is based on an assumption of a linear relationship between the returns of each security and a set of common factors this is the assumption of linear return generating models which form an integral part of the structure of many asset pricing theories for example arbitrage pricing theory apt as developed by ross 1976 the interpretation is that the common factors represent sources of systematic or nondiversifiable risk and the idiosyncratic component of returns represents diversifiable risks our focus here is not on testing a particular asset pricing model per se but on developing empirical evidence for the existence of stylized facts regarding money market returns the stylized facts take the form of the existence measurement and interpretation of the common factors that are found in money markets our attempt to measure and interpret these sources of systematic risk may eventually lead to the construction of observable eco
