the energy ladder theoretical myth or empirical truth results from a meta analysis abstract modern fuels are an important enabler of social and economic development still over 2 billion people rely on traditional biomass for their daily energy needs to overcome the negative effects of traditional energy on human health and the environment and to enhance the livelihood conditions of the poor a transition towards cleaner and more efficient forms of energy is needed understanding household fuel choice and fuel switching behaviour is of vital importance in search for policies to support such a transition process this paper adds to the existing energy transition literature in two ways first we provide a novel conceptual framework to analyze the decision environment underlying energy and fuel choices second we apply this framework in a meta analysis of existing choice models investigating energy switching and stacking behaviour in urban and rural areas in developing countries the meta analysis shows that socio economic household characteristics appear to receive most attention so far in identifying groups of fuel users while relatively little information is available on the impact of the external decision context on household energy choices

will business cycles in the euro area converge a critical survey of empirical research this survey of business cycle synchronization in the european monetary union focuses on two issues have business cycles become more similar and which factors drive business cycle synchronization we conclude that business cycles in the euro area have gone through periods of both convergence and divergence still there is quite some evidence that during the 1990s business cycle synchronization in the euro area has increased higher trade intensity is found to lead to more synchronization but the point estimates vary widely the evidence for other factors affecting business cycle synchronization is very mixed

some empirical evidence on the effects of shocks to monetary policy on exchange rates this paper investigates the effects of shocks to u s monetary policy on exchange rates we consider three measures of these shocks orthogonalized shocks to the federal funds rate orthogonalized shocks to the ratio of nonborrowed to total reserves and changes in the romer and romer index of monetary policy in sharp contrast to the literature we find substantial evidence of a link between monetary policy and exchange rates specifically according to our results a contractionary shock to u s monetary policy leads to i persistent significant appreciations in u s nominal and real exchange rates and ii significant persistent deviations from uncovered interest rate parity in favor of u s interest rates

long term growth and short term economic instability when learning by doing is at the origin of growth the long run growth rate should be negatively related to the amplitude of the business cycle if human capital accumulation is increasing and concave in the cyclical component of production empirical evidence strongly supports this nding for industrialized countries and european regions using the standard control variables we nd that countries and regions that have a higher standard deviation of growth and of unemployment have lower growth rates the result does not come from an e ect of instability on investment the negative relation however does not hold for non industrialized countries for which learning by doing may not to be the main engine of growth 2000 elsevier science b v all rights reserved jel classixcation o40 e32

wage mobility in the united states this paper examines the mobility of individuals through the wage and earnings distributions using 1979 1991 data from the national longitudinal survey of youth lifetime wages will be more equally distributed than wages from any single year if individuals change position in the wage distribution over time the results suggest that mobility is predominantly within group mobility reducing wage inequality by 12 26 over a four year horizon a detailed examination of within group mobility using year to year estimates of transition probabilities among quintiles of the distribution reveals similar general patterns across all skill groups mobility declined significantly over the years especially at the lower end of the wage and earnings distributions

the asymmetric behavior and procyclical impact of asset correlations abstract this paper examines the behavior of asset correlations with the market returns in the asymptotic single risk factor asrf approach of the basel ii accord on regulatory capital requirement over a sample period from 1988 to 2007 we find that asset correlations are positively related to firm size but negatively related to firm default probability asset correlations are also industry specific as firms in media transportation pharmaceutical and semiconductor industries exhibit higher asset correlations than those in retail and consumer staples most importantly asset correlations are asymmetric and have a procyclical impact on the real economy after controlling for these effects they tend to rise during economic downturns but decline during economic upturns the average magnitude of the rise is larger than that of the decline these findings suggest that asset correlations may be underestimated during economic downturns and may provide policy implications for the capital requirement framework

industry classifications and return comovement a company s industry affiliation is commonly used to construct homogeneous stock groupings for portfolio risk management relative valuation and peer group comparisons a variety of industry classification systems have been adopted however creating disagreements as to companies industry assignments this analysis of the global industry classification system gics and fama french system indicates that common movement in returns and operating performance resulting from industry effects is stronger for stocks of large companies than for those of small companies also increasingly fine levels of disaggregation improve discrimination up to six digit gics codes after which the benefits tail off stock groupings based on industry exhibit stronger out of sample homogeneity than groups formed from statistical cluster analysis

cyclical and causal relations between real wages and employment in the eu this paper analyses and compares the joint behaviour of real wages and employment over the business cycle in the european union eu economies using both annual and quarterly data since 1960 further investigation of the cointegrating properties and the existence of causal effects in the real wage employment relation is undertaken by employing appropriate var models the evidence suggests weak procyclical or acyclic behaviour of real wages relative to cyclical employment in the quarterly data and stronger procyclicality in the annual data thus confirming the dunlop tarshis result for the majority of the eu economies with a few exceptions no cointegrating relations were detected while the granger causality tests suggest either weak or lack of unidirectional causality finally the sensitivity analysis showed that the filtering method has not much influence on the results but the choice of deflator may overturn them in certain cases

income dynamics and life cycle inequality mechanisms and controversies this study focuses on the transmission of inequality over the working life a model of constrained intertemporal choice is used to provide structure to the distributional dynamics of wages earnings income and consumption the mechanisms used to insure labour market shocks are examined in a partial insurance setting where the manner and scope for insurance depends on the access to credit the information available to consumers and the durability of income shocks drawing on recent research family labour supply the credit market and the tax system are all shown to play a key role these mechanisms vary in importance across different points of the life cycle and the business cycle 2014 the author s the economic journal published by john wiley sons ltd on behalf of royal economic society

credit risk drivers evaluating the contribution of firm level information and of macroeconomic dynamics abstract understanding if credit risk is driven mostly by idiosyncratic firm characteristics or by systematic factors is an important issue for the assessment of financial stability by exploring the links between credit risk and macroeconomic developments we observe that in periods of economic growth there may be some tendency towards excessive risk taking using an extensive dataset with detailed information for more than 30 000 firms we show that default probabilities are influenced by several firm specific characteristics when time effect controls or macroeconomic variables are also taken into account the results improve substantially hence though the firms financial situation has a central role in explaining default probabilities macroeconomic conditions are also very important when assessing default probabilities over time

a comparative analysis of current credit risk models the new bis 1998 capital requirements for market risks allows banks to use internal models to assess regulatory capital related to both general market risk and credit risk for their trading book this paper reviews the current proposed industry sponsored credit value at risk methodologies first the credit migration approach as proposed by jp morgan with creditmetrics is based on the probability of moving from one credit quality to another including default within a given time horizon second the option pricing or structural approach as initiated by kmv and which is based on the asset value model originally proposed by merton merton r 1974 journal of finance 28 449 470 in this model the default process is endogenous and relates to the capital structure of the firm default occurs when the value of the firm s assets falls below some critical level third the actuarial approach as proposed by credit suisse financial products csfp with creditrisk and which only focuses on default default for individual bonds or loans is assumed to follow an exogenous poisson process finally mckinsey proposes creditportfolioview which is a discrete time multi period model where default probabilities are conditional on the macro variables like unemployment the level of interest rates the growth rate in the economy which to a large extent drive the credit cycle in the economy 2000 elsevier science b v all rights reserved

the cyclical behaviour of prices g 7 versus non g7 countries the cyclical behaviour of prices and inflation is investigated for g 7 and seven non g7 countries for the postwar period the quarterly prices are shown to be clearly countercyclical in the g 7 countries while they are much less so in the non g7 countries inflation is shown to move procyclically and this is more clearly pronounced in the g 7 than non g7 countries this discrepancy in results may result from the demand management policies that these non g7 countries have adopted in the past and this cautions the students of business cycles to pay attention to the peculiarities of each economy when modelling the business cycle

taxation and political business cycles in eu economies this paper examines whether incumbent national governments of 11 member states of the european union manipulated the tax policy instruments at their disposal in order to create national political business cycles opportunistic or partisan the empirical evidence based on data concerning the 1965 to 1997 period does not support this hypothesis rather it appears that governments have pursued stabilization policies

efficiency wages and the business cycle puzzle abstract the main thrust of this work is to open the real business cycle rbc methodology to non walrasian considerations and reciprocally to submit some non walrasian models to the discipline of the rbc approach in doing so we provide a first rbc model with involuntary unemployment and a suboptimal equilibrium path we also demonstrate the promise and difficulty of resolving the business cycle puzzle by appealing to quantity rationing in the labor market

deflation and depression is there an empirical link are deflation and depression empirically linked no concludes a broad historical study of inflation and real output growth rates deflation and depression do seem to have been linked during the 1930s but in the rest of the data for 17 countries and more than 100 years there is virtually no evidence of such a link

unsecured credit markets are not insurance markets abstract we study the extent to which unsecured credit markets have altered the transmission of increased income risk to consumption variability over the past several decades we find that unsecured credit markets pass through increased income risk to consumption irrespective of bankruptcy policy and the information possessed by lenders if risk sharing has indeed improved over this period the reasons do not therefore lie in the unsecured credit market

capital formation in japan introduction this chapter analyses the relationship between the input of capital and economic growth in japan during the past century the assigned task of exploring the role of investment in japan necessarily imposes a certain sectoral as well as temporal emphasis only relatively little attention will have to be devoted to agriculture since this sector never became an important recipient of either public or private capital in japan at least an understanding of the advances created by a rising level of investment deals largely with the growth of modern nonagricultural industry this also means that unlike taira and yamamura we must concentrate especially on the history of the twentieth century when factories machines and new social overhead implements reached sizeable dimensions for the first time of course no attempt will be made to slight the crucial transitional years of the meiji era or even the preceding years of tokugawa rule but one should always keep at the forefront the sharp distinction between the hesitant beginnings of economic modernization in the late nineteenth century and its full flowering during the past sixty odd years one further limiting item should be mentioned at the outset we are concerned with the input of capital i e with the investment rather than the saving side of the equation how the necessary funds were raised by individuals banks the state or foreigners will be treated only as a side issue but to a considerable extent this matter has been studied by other authors

the hodrick prescott filter the slutzky effect and the distortionary effect of filters abstract i construct a metric based on optimal filtering for measuring the distortionary effect of business cycle filters the distortionary effect of a filter depends both on the power transfer function of the filter and on the spectrum of the filtered time series the metric is used for two purposes first to determine the optimal value of the smoothing parameter in the hodrick prescott filter hp filter secondly to measure the size of distortions of ten different filters the slutzky effect is a special case of a more general pattern of distortions and it is shown that the alleged slutzky effect of the hp filter is due to an insufficient distinction between the effect of filtering with an ideal high pass filter and the distortionary effect of the hp filter

financial contagion and international portfolio flows financial contagion is an issue of interest to policymakers and portfolio managers in the presence of contagion the benefits of geographical diversification may be overstated contagion is defined independently of changes in macroeconomic fundamentals it corresponds to a situation in which shocks in one country spread to another country in a significantly more pronounced manner than during quiet times in the study reported here i attempted to measure contagion from daily cross border portfolio flows using data from state street bank and trust company i constructed three indexes for 1996 through 2000 i found little statistical evidence of contagion but the weighted index that measured the contagiousness of flows reached its four year low in august 1998 suggesting that the russian crisis was characterized by both contagion and large aggregate outflows i also found that contagion appears to be regional and that the developed countries seem to be sheltered from contagion

from linear fuel switching to multiple cooking strategies a critique and alternative to the energy ladder model abstract promoting sustainable development requires evaluating the technical and policy options that will facilitate the adoption and use of energy efficient and less polluting cooking stoves and practices the transition from traditional to modern fuels and devices has been explained by the energy ladder model that suggests that with increasing affluence a progression is expected from traditional biomass fuels to more advanced and less polluting fuels in this paper we evaluate the energy ladder model utilizing data from a four year 1992 96 case study of a village in mexico and from a large scale survey from four states of mexico we show that an alternate multiple fuel model of stove and fuel management based on the observed pattern of household accumulation of energy options rather than the simple progression depicted in the traditional energy ladder scenario more accurately depicts cooking fuel use patterns in rural households the multiple fuel model integrates four factors demonstrated to be essential in household decision making under conditions of resource scarcity or uncertainty a economics of fuel and stove type and access conditions to fuels b technical characteristics of cookstoves and cooking practices c cultural preferences and d health impacts this model also allows better estimates of the expected fuelwood demand and indoor air pollution in rural households

household biomass energy choice and its policy implications on improving rural livelihoods in sichuan china abstract it is widely known that a switch from traditional biomass energy to modern clean safe and efficient energy could improve local rural livelihoods by enhancing the access to high quality energy and reducing the negative impacts of traditional biomass energy on health environment and living standards hence in this paper we used alternative specific conditional logit model asclm to examine the rural household energy choice behaviors in sichuan province of china from the perspective of revealed and stated preferences the results show that the fuel switching in our study region is not a simple unidirectional process from traditional biomass energy to modern fuels as incomes improve household energy choice behaviors could be not only affected by energy specific characteristics such as fuel price smoky level and safety risk but also influenced by household specific factors such as income level age and educational level of the decision maker household demographic structure number of people frequently eating at home distance to the nearest biomass collecting spot and household location suggesting that government should attach more importance to simultaneously improve energy quality control energy price and enhance household socio economic status

the pricing of deposit insurance in the presence of systematic risk based on the merton 1977 put option framework we develop a deposit insurance pricing model that incorporates asset correlations a measurement for the systematic risk of a bank to account for the risk of joint bank failures estimates from our model suggest that actuarially fair risk based deposit insurance that considers only individual bank failure risk is underpriced leaving insurance providers exposed to net losses our estimates also capture the size premium where big banks are priced with higher deposit insurance than small banks this result is particularly relevant to the current regulatory concerns on big banks that are too big to fail above all our approach provides a unifying framework for integrating risk based deposit insurance with risk based basel capital requirements

measuring business cycles a modern perspective in the first half of this century special attention was given to two features of the business cycle 1 the comovement of many individual economic series and 2 the different behavior of the economy during expansions and contractions both of these attributes were ignored in many subsequent business cycle models which were often linear representations of a single macroeconomic aggregate however recent theoretical and empirical research has revived interest in each attribute separately notably dynamic factor models have been used to obtain a single common factor from a set of macroeconomic variables and nonlinear models have been used to describe the regime switching nature of aggregate output we survey these two strands of research and then provide some suggestive empirical analysis in an effort to unite the two literatures and to assess their usefulness in a statistical characterization of business cycle dynamics

international real business cycles among heterogeneous countries abstract business cycle statistics differ widely across countries for some aggregates especially for trade related variables part of these variations relates to the size of the economies and to their distance from each other this paper asks whether a three country model is able to display the marked diversity of business cycle statistics observed across countries the model is calibrated to two specific examples canada and switzerland our findings are that most of the diversity of the business cycles can be accounted for by size and distance and that trade is not a strong channel of diffusion of cycles

current real business cycle theories and aggregate labor market fluctuations hours worked and the return to working are weakly correlated traditionally the ability to account for this fact has been a litmus test for macroeconomic models existing real business cycle models fail this test dramatically we modify prototypical real business cycle models by allowing government consumption shocks to influence labor market dynamics this modification can in principle bring the models into closer conformity with the data our empirical results indicate that it does

preferences for domestic fuel analysis with socio economic factors and rankings in kolkata india abstract the choice of domestic fuel is a matter of great concern for households and policy makers in india this paper investigates the demand for domestic fuels when households face four choices fuelwood coal kerosene and lpg the study is based on a survey of 500 households in kolkata india the demand estimates are conducted using a two stage process where the first stage investigates choice and the second the quantity used determinants of fuel demand are identified and their relative importance shown extending the study the paper also analyses the choice of the main cooking fuel in terms of the households stated rankings of six fuels for five attributes the policy discussion indicates that subsidies have less potential to reduce polluting fuels such as coal and fuelwood due to weak cross price elasticities while increased availability of lpg and potentially also increased awareness of indoor air pollution have greater prospect

cooking fuel choice in rural china results from microdata abstract unclean cooking fuel is widely used in the developing world and it is the main indication of energy poverty in rural china in this paper we investigate the situation transition and determination of fuel choice in china s rural household cooking using the large scale micro survey data of china health and retirement longitudinal study charls we find that there is a big gap in using commercial cooking fuels between rural and urban households 60 of the rural households adopt traditional biomass resource as their main fuel for cooking in 2011 while this figure is less than 5 in the urban we also identify a significant spatial divide in fuel choice in southeastern coastal areas about 40 of the rural households prefer solid fuels while this figure jumps to over 80 in northeastern areas the longitudinal data also reveal a significant transition from traditional to modern fuels from 2008 to 2012 moreover the distance to the most commonly used farmer s market education background coal price and female labor participation are all influential in determining the households choices

consumption inequality and family labor supply we examine the link between wage and consumption inequality using a life cycle model incorporating consumption and family labor supply decisions we derive analytical expressions for the dynamics of consumption hours and earnings of two earners in the presence of correlated wage shocks nonseparability progressive taxation and asset accumulation the model is estimated using panel data for hours earnings assets and consumption we focus on family labor supply as an insurance mechanism and find strong evidence of smoothing of permanent wage shocks once family labor supply assets and taxes are properly accounted for there is little evidence of additional insurance jel d12 d14 d91 j22 j31

business cycles in switzerland a comparative study abstract the goal of this paper is to provide an empirical description of business cycles in switzerland and a comparison with business cycles in other countries we adopt a view of business cycles as a set of regularities in the movements and the co movements of economic aggregates common to all decentralized economies lucas 1977 and test whether switzerland conforms to this view in order to identify the appropriate cyclical series we follow a procedure proposed by hodrick and prescott 1980 we then compute correlations of various types we test their stability through time and compare with corresponding estimates for the u s france germany and the u k

international evidence on the historical properties of business cycles we contrast properties of real quantities with those of price levels and stocks of money for ten countries over the last century although the magnitude of output fluctuations has varied across countries and periods relations among real quantities have been remarkably uniform properties of price levels however exhibit striking differences between periods inflation rates are more persistent after world war ii than before and price level fluctuations are typically procyclical before world war ii and countercyclical afterward fluctuations in money are less highly correlated with output in the postwar period but are no more persistent than in earlier periods jel e32 e31

relative wage movements and the distribution of consumption we analyze how relative wage movements among birth cohorts and education groups affected the distribution of household consumption and economic welfare our empirical work draws on the best available cross sectional data sets to construct synthetic panel data on u s consumption labor supply and wages during the 1980s we find that low frequency movements in the cohort education structure of pretax hourly wages among men drove large changes in the distribution of household consumption the results constitute a spectacular failure of between group consumption insurance a failure not explained by existing theories of informationally constrained optimal consumption behavior a welfare analysis indicates that the cost of between group consumption variability is larger than the cost of aggregate consumption variability by two orders of magnitude

business cycles in the united kingdom facts and fictions this paper documents the statistical properties of contemporary business fluctuations in the united kingdom we study the period 1956 90 using quarterly detrended data on key aggregate variables we compute selected moments of the data compare our results with those for the united states and rigorously test for dynamic instabilities our findings confirm the existence of substantive cyclical regularities both across countries and across time some notable cross country differences are also identified conclusions about stability are shown to be potentially sensitive to the method of testing in general cross correlations are appreciably more stable than standard deviations

comovement in gdp trends and cycles among trading partners abstract it has long been recognized that business cycle comovement is greater between countries that trade more intensively with one another however nations face shocks to both the cyclical and trend components of their gdp series contrary to the result for cyclical fluctuations we find comovement of shocks to the trend component of real gdp is weaker among countries that trade more intensively with one another we simulate changes in ten year output growth correlations corresponding to the estimated effects of trade and show that the impact of trade on trend comovement is quantitatively more important than its effect on cyclical comovement

household fuel use in developing countries review of theory and evidence because of recent concerns about the negative externalities of traditional fuel use on the environment and health the issue of the household fuel transition in developing countries from dirty fuels towards clean fuels has received growing research attention this paper provides an up to date survey of the economic literature on household fuel use in these countries first we present the conceptual and theoretical frameworks then we discuss the empirical results that show how a wide range of factors drive the household fuel transition finally we suggest priorities for policy initiatives and highlight areas of future research

detrending stylized facts and the business cycle the stylized facts of macroeconomic time series can be presented by fitting structural time series models within this framework we analyse the consequences of the widely used detrending technique popularised by hodrick and prescott 1980 it is shown that mechanical detrending based on the hodrick prescott filter can lead investigators to report spurious cyclical behaviour and this point is illustrated with empirical examples structural time series models also allow investigators to deal explicitly with seasonal and irregular movements that may distort estimated cyclical components finally the structural framework provides a basis for exposing the limitations of arima methodology and models based on a deterministic trend with a single break

business cycles in international historical perspective business cycle models seek to answer the question of why economies go through cycles of recession and recovery or boom and bust any theory of the business cycle makes two sorts of claims what shocks are most important in disturbing the economy and what economic structure is necessary for propagating these shocks for example one common explanation of business cycles begins with monetary shocks and then seeks to explain why monetary shocks are not purely neutral as neoclassical theory would have it and instead have real effects at least in the short term early models in this vein were often implicitly or explicitly based on the proposition that markets do not clear continuously early equilibrium real business cycle theories instead emphasized the importance of real shocks especially to technology which may cause socially efficient fluctuations even when markets are always in equilibrium more recent models have attempted to marry the equilibrium approach to macroeconomics with the substantive keynesian ideas that money is not neutral and that economic fluctuations are costly new keynesian theories of the business cycle admit the possibility of a number of economic shocks including monetary and technology shocks but then focus on explaining how nominal price rigidities within the economy can turn these shocks into recessions or booms other models show that business cycles driven by keynesian animal spirits are consistent with rigorous microfoundations and rational expectations seeking empirical evidence for and against these various approaches we turn business cycle theories loose on perhaps the greatest macroeconomic laboratory

external factors in emerging market recoveries an empirical investigation abstract we estimate conditional duration models to analyse recovery processes in emerging market economies our reduced form specification is parsimonious as we focus on exogenous factors such as the effect of growth in the us eu and japan on the prospects for recovery in emerging market economies experiencing recessions the model confirms the importance of external factors in recovery processes however the short run effect of japanese growth on recovery prospects is unconventional weak economic conditions in japan turn out to facilitate recoveries

stock prices and volume the authors undertake a comprehensive investigation of price and volume co movement using daily new york stock exchange data from 1928 to 1987 they adjust the data to take into account well known calendar effects and long run trends to describe the process they use a seminonparametric estimate of the joint density of current price change and volume conditional on past price changes and volume four empirical regularities are found 1 positive correlation between conditional volatility and volume 2 large price movements are followed by high volume 3 conditioning on lagged volume substantially attenuates the leverage effect and 4 after conditioning on lagged volume there is a positive risk return relation article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

historical energy price shocks and their changing effects on the economy abstract the purpose of this paper is to identify the changes in the impact of energy shocks on economic activity with an interest in assessing if an economy s vulnerability and resilience to shocks improved with economic development using data on the united kingdom over the last three hundred years the paper identifies supply aggregate demand and residual shocks to energy prices and estimates their changing influence on energy prices and gdp the results suggest that the impacts of supply shocks rose with its increasing dependence on coal and declined with its partial transition to oil however the transition from exporting coal to importing oil increased the negative impacts of demand shocks more generally the results indicate that improvements in vulnerability and resilience to shocks did not progress systematically as the economy developed instead the changes in impacts depended greatly on the circumstances related to the demand for and supply of energy sources if these experiences are transferable to future markets a transition to a diversified mix of renewable energy is likely to reduce vulnerability and increase resilience to energy price shocks

asymmetric effects of money supply shocks and trend inflation in recent years a number of empirical studies have presented evidence that money supply shocks have asymmetric effects that is unexpected negative changes in the money supply slow the economy more than unexpected positive changes accelerate the economy evidence of asymmetry was documented by cover 1992 for the postwar u s economy and his finding was confirmed by de long and summers 1988 morgan 1993 rhee and rich 1995 and karras 1996a b stimulated by these empirical works several attempts have been made to provide microeconomic foundations for the asymmetric effects of money supply shocks 1 among those theories this paper examines the one that focuses on asymmetric price adjustment and let us call it a sticky price theory money supply shocks will have asymmetric effects on real output if prices are less flexible downward than upward this sticky price theory was proposed by tsiddon 1993 ball and mankiw 1994 and caballero and engel 1992 by employing a menu cost model the above researchers show that positive trend inflation can produce the asymmetric effects of money supply shocks the logic of their theory is the following along with price adjustment costs positive trend infla

common and country specific fluctuations in productivity investment and the current account abstract dynamic factor analysis and kalman filtering are used to construct a measure of common economic activity for the g7 countries we find that the common fluctuations are strongly associated with movements in us investment common fluctuations have substantial impact on fluctuations in both productivity and investment in these countries but very little impact on the current account country specific investment fluctuations have a significant negative impact on the current account while country specific productivity movements have little independent effect these findings are shown to be generally consistent with the predictions of a multi country dynamic model calibrated to the empirical decomposition of productivity shocks

comparisons of business cycles in the ec idiosyncracies and regularities annual data since 1960 and the real business cycle model as a guidance the evidence suggests that there are remarkable similarities between the business cycle pattern of these countries despite significant differences in the patterns of fiscal and monetary policies and the terms of trade we take this evidence to suggest that the type of shocks and the propagation mechanism is fairly similar across the ec countries hence the process of european integration under a set of uniform institutions and policies should not be a problem as far as the business cycle is concerned

the cyclical effects of the basel ii capital requirements abstract capital requirements play a key role in the supervision and regulation of banks the basel committee on banking supervision is in the process of changing the current framework by introducing risk sensitive capital charges some fear that this will unduly increase the volatility of regulatory capital furthermore by limiting the banks ability to lend capital requirements may exacerbate an economic downturn the paper examines the problem of capital induced lending cycles and their pro cyclical effect on the macroeconomy in greater detail it finds that the capital buffer that banks hold on top of the required minimum capital plays a crucial role in mitigating the impact of the volatility of capital requirements

structural unemployment cyclical unemployment and income inequality this is the first study that decomposes unemployment into its structural and cyclical components and investigates their impact on income distribution controlling for the influence of inflation increases in structural unemployment have a substantial aggravating impact on income inequality inflation has a progressive impact which is due to the unexpected component the study demonstrates that previous work failed to take into account the stochastic trend behavior of the variables consequently specifications used by previous research cannot predict the behavior of income shares after 1983 whereas the specification used by this paper generates accurate forecasts the results also indicate that a sustained gnp growth is not necessarily associated with an improvement in income inequality because sustained gnp growth can coexist with increased structural unemployment

asset correlations in single factor credit risk models an empirical investigation abstractthe internal ratings based irb approach based on a single risk factor model was designed by the basel committee on banking supervision bcbs to determine banks regulatory credit risk capital key inputs of the model asset correlations are prescribed by the regulator relevant banks must use them for capital determination to ascertain whether these correlations are too onerous or too lenient empirical asset correlations embedded in loss data spanning different loss milieu were backed out of the regulatory model static and rolling correlations over a period of time were compared with the prescribed correlations for developed and developing economies and found to be significantly more conservative

the macroeconomic implications of rising wage inequality in the united states in recent decades american workers have faced a rising college premium a narrowing gender gap and increasing wage volatility this paper explores the quantitative and welfare implications of these changes the framework is an incomplete markets life cycle model in which individuals choose education intrafamily time allocation and savings given the observed history of the u s wage structure the model replicates key trends in cross sectional inequality in hours worked earnings and consumption recent cohorts enjoy welfare gains on average as higher relative wages for college graduates and for women translate into higher educational attainment and a more even division of labor within the household

consumption inequality and income uncertainty this paper places the debate over using consumption or income in studies of inequality growth in a formal intertemporal setting it highlights the importance of permanent and transitory income uncertainty in the evaluation of growth in consumption inequality we derive conditions under which the growth of variances and covariances of income and consumption can be used to separately identify the growth in the variance of permanent and transitory income shocks household data from britain for the period 1968 1992 are used to show a strong growth in transitory inequality toward the end of this period while younger cohorts are shown to face significantly higher levels of permanent inequality

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

methodological and empirical issues in real business cycle theory abstract in this paper we argue that the major impact of the rbc literature has been to propose a new methodology for macroeconomics this methodology is distinguished first by the importance it attributes to the empirical description of the phenomena to be explained and second by the use of this description in conjunction with quantitative theorizing i e the construction of computable general equilibrium models whose characteristic statistics match those of the data in accordance with this approach we first report on the current state of knowledge concerning business cycle regularities and conclude that additional empirical effort is called for in order to arrive at the appropriate basis for theorizing we then examine the performance of existing models and evaluate the case for integrating monetary factors and demand shocks into them lastly we review the recent efforts to explain the employment variability puzzle and argue that the search for a solution naturally leads to the incorporation of significant non walrasian features into the rbc framework

asymmetric effects of the business cycle on bank credit risk abstract prior empirical research on the relation between credit risk and the business cycle has failed to properly investigate the presence of asymmetric effects to fill this gap we examine this relation both at the aggregate and the bank level exploiting a unique dataset on italian banks borrowers default rates we employ threshold regression models that allow to endogenously establish different regimes identified by the thresholds over below which credit risk is more less cyclical we find that not only are the effects of the business cycle on credit risk more pronounced during downturns but cyclicality is also higher for those banks with riskier portfolios

government activities and tests of the long run implications of the neoclassical growth model for canada this paper shows that the conclusions of time series analyses of the long run properties of the one factor neoclassical stochastic growth model under uncertainty are robust with regard to alternative ways of handling government expenditures in particular when annual canadian data from 1946 to 1993 are used the hypothesis that the log ratios of consumption to output and investment to output are stationary is rejected even when government expenditures are treated as perfect substitutes for private ones and aggregated with the corresponding private variables

do government purchases affect unemployment we estimate the effect of government purchases on unemployment in 20 oecd countries for the period 1980 2007 an increase in government purchases equal to one percent of gdp is found to reduce unemployment by about 0 3 percentage points in the same year the effect is greater and more persistent under less employment friendly labour market institutions and greater and more persistent under a fixed exchange rate regime than under a floating regime the effect is also greater in downturns than in booms the effect on unemployment reflects a corresponding positive effect of increased government purchases on the employment to population rate this article is protected by copyright all rights reserved

consumption and labor supply with partial insurance an analytical framework we develop a model with partial insurance against idiosyncratic wage shocks to quantify risk sharing closed form solutions are obtained for equilibrium allocations and for moments of the joint distribution of consumption hours and wages we prove identification and demonstrate how labor supply data are informative about risk sharing the model estimated with us data over the period 1967 2006 implies that i 39 percent of permanent wage shocks pass through to consumption ii the share of wage risk insured increased until the early 1980s and iii preference heterogeneity is important in accounting for observed dispersion in consumption and hours jel e21 e23 e31 e52

full insurance in the presence of aggregate uncertainty this paper tests implications of full consumption insurance the object is to determine how much mileage can be obtained from a model with complete markets with such features as private information or liquidity constraints omitted the implication exploited is that individual consumption responds to aggregate risk but not to idiosyncratic risk the test involves regressing the change in household consumption onto the change in aggregate consumption and other right hand side variables such as the change in household income and change in employment status all variables other than the change in aggregate consumption are predicted to be insignificant in explaining the change in household consumption with observations on consumption and income for 10 695 households from the consumer expenditure survey the results are mixed the results for one specification exponential utility are mostly consistent with full consumption insurance the results for the other specification power utility are not

swedish business cycles 1861 1988 abstract we examine swedish business cycle data for 1861 1988 in the time domain as well as in the frequency domain there is evidence of a business cycle in the form of considerable spectral mass for cycles between three and eight years the variability of the series varies considerably over time for most series it is highest in the inter war period relative variability is fairly stable over time cross section ratios between moving standard deviations for the series do not change much comovements are also stable over time correlation coefficients do not change much either

business cycles under monetary union a comparison of the eu and us reserve districts in the usa and the 15 countries that make up the eu the comparison is suggestive of what might be expected to emerge in the way of business cycle synchronization from a monetary union between the member states of the eu now simply non decimal denominations of the euro and the national central banks of the 11 are branches of the european system of central banks many prominent observers doubted that europe would ever reach this stage and many continue to believe that monetary union between such a large and dispar ate group of countries is fundamentally unsound a key element in the argu ments of many critics of emu is the degree of business cycle asynchronicity between the member states of the eu this paper contributes to the ongoing debate by documenting key differences and similarities between business cycles in the eu and business cycles in the 12 federal reserve districts in the united states the practice of looking to the us experience for insights into the problems and functioning of a monetary union has a long precedent in the literature on fixed exchange rates in general and in the literature on emu in particular for example in making an argument for fixed exchange rates rolnick and weber 1994 note that the usa can be viewed as having a system of fixed exchange rates between currencies issued by the 12 regional federal reserve banks they argue that the notes issued by the 12 banks are not strictly ident ical and that the difference between the notes creates the possibility that the united states could have a system of floating exchange rates among the 12 federal reserve districts 1 rolnick and weber go on to examine the features of the relationship among the 12 regional federal reserve banks that make a system of fixed exchange rates between them feasible in the process drawing lessons for how a monetary union among the countries of the eu might work the analysis in this paper complements earlier analyses in a number of ways the resurgence of interest in business cycle research over the past 20

household energy preferences for cooking in urban ouagadougou burkina faso abstract an extensive survey on household expenditures in ouagadougou the capital of burkina faso was used to analyze the factors determining urban household energy choices using a multinomial logit model wood energy remains the preferred fuel of most urban households in the country though rational the choice is not sustainable as it portends a threat to the savanna woodlands and the economy many important policies have been adopted by public authorities to minimize household wood energy consumption and to substitute it by alternative fuel despite the magnitude of all these policies the depletion rate of the forest resource is increasing a kind of inertia is thus observed for household preferences for cooking fuel this model analyzes the sociological and economic variables of household energy preferences for cooking in ouagadougou the analyses show that the inertia of household cooking energy preferences are due to poverty factors such as low income poor household access to electricity for primary and secondary energy low house standard household size high frequency of cooking certain meals using woodfuel as cooking energy the descriptive analyses show that the domestic demand for wood energy is strongly related to household income the firewood utilization rate decreases with increasing household income in other words this fuel appears as a transition good for these households which aim for other sources of energy for cooking that are more adapted for urban consumption this implies that a price subsidy policy for liquid petroleum gas lpg and its cook stoves could significantly decrease the utilization rate of wood energy

adjustment costs in investment time preferences and the current account abstract this paper studies the effects of supply and demand shocks on the optimal investment and savings decisions of economic agents in a small open economy the two building blocks of the setup are adjustment costs in investment and a recursive time preference structure it is shown that the model can mimic certain stylized facts

fuel switching in slum and non slum households in urban india improving access to modern fuels is essential in developing countries for reducing adverse human health and environmental impacts caused by traditional fuels fuels use in developing countries is heterogeneous across households this paper estimates drivers of fuel switching in non slum and slum households in urban india using a discrete choice model on a nationally representative micro data the choices considered are three categories of cooking fuels traditional firewood dung crop residue and coal charcoal modern kerosene and liquefied petroleum gas lpg and mixed fuels the results suggest that the patterns of fuels use are consistent with the energy ladder theory in urban india in addition to income the major determinants of modern fuels uptake are fuels prices access to electricity and water supply and education attainment the increasing price of lpg affects the willingness to change fuels for low income non slum and the high income slum households negatively the analyses make a strong case for applying differential subsidies on modern fuels employing multidimensional aspects of poverty moreover there is a need for partial diversion of existing fuels subsidies on improving physical and social capitals which will result in uptake of modern fuels particularly among disadvantaged communities

an international comparison of lifetime inequality how continental europe resembles north america we compare earnings inequality and mobility across the united states canada france germany and the united kingdom during the late 1990s a flexible model of earnings dynamics that isolates positional mobility within a stable earnings distribution is estimated earnings trajectories are then simulated and lifetime annuity value distributions are constructed earnings mobility and employment risk are found to be positively correlated with base year inequality taken together they produce more equalization in countries with high cross section inequality such that the countries in our sample have more similar lifetime inequality levels than cross section measures suggest

from earnings inequality to consumption inequality this paper studies the paths from inequality in earnings to inequality in household consumption we show that careful study of the evolution of the variances and covariances of earnings and consumption within cohorts across time can identify permanent and transitory shocks we present an application to the evolution of inequality in the united kingdom we extend previous results to recognise separate earnings of partners in couples

electricity forward curves with thin granularity theory and empirical evidence in the hourly epexspot market we propose a constructive definition of electricity forward price curve with cross sectional timescales featuring hourly frequency on the curve is jointly consistent with both risk neutral market information represented by baseload and peakload futures quotes and historical market information as mirrored by periodical patterns exhibited by the time series of day ahead prices from a methodological standpoint we combine nonparametric filtering with monotone convex interpolation such that the resulting forward curve is pathwise smooth and monotonic cross sectionally stable and time local from an empirical standpoint we exhibit these features in the context of epex spot and eex derivative markets we perform a backtesting analysis to assess the relative quality of our forward curve estimate compared to the benchmark market model of benth koekebakker and ollmar 2007

life cycle economies and aggregate fluctuations do the implications for business cycle issues change when we switch from studying infinitely lived representative agent models to more sophisticated demographic structures with finitely lived agents this article addresses that question by using a large overlapping generations model that is calibrated to u s demographic properties microeconomic evidence and national income and product accounts the finding is that the answers obtained are basically the same for the two kinds of models the article also explores the relative volatility of hours across age groups an issue that cannot be addressed by using the infinitely lived representative agent abstraction

urban household energy use in india efficiency and policy implications biomass based fuels are being steadily replaced with modern fossil fuels and electricity in cities of developing countries the latter energy sources are more convenient and efficient to use and produce less local pollutants this fuel transition has accompanied economic growth in many cities empirical data to substantiate these generalizations are being gathered by researchers we report on a recent survey of household energy use in the city of hyderabad india the survey reveals that the underlying fuel transition is consistent with that in other developing country cities government policy however has favored the rich because of the inequities in fuel and equipment availability among income groups we report the major findings of the survey in context of other data for india and suggest policy changes to redress these inequities

money inflation and output under fiat and commodity standards we examine the behavior of money inflation and output under fiat and commodity standards to better understand how changes in monetary policy affect economic activity using long term historical data for 15 countries we find that under fiat standards the growth rates of various monetary aggregates are more highly correlated with inflation and with each other than under commodity standards money growth inflation and output growth are also higher in contrast we do not find that money growth is more highly correlated with output growth under one standard than under the other

gaining ground poverty in the postwar united states official measures of poverty in the united states are compiled by the bureau of the census by comparing a household s income level to a prespecified threshold from a theoretical perspective it is more appropriate to evaluate the level of poverty using a consumption based measure of household welfare in this paper i evaluate the level of poverty using expenditure data from the consumer expenditure survey i find that consumption based poverty rates are much lower than those based on income the trend in the poverty rate in the united states is sensitive to the price index and equivalence scales used to adjust the poverty thresholds

nominal inertia and shock persistence in uk business cycles a structural var methodology is used for uk data to identify and map out the effects of innovations in the money supply employment output wages and prices moreover bands of two standard errors are computed for the impulse response functions so that comment may be made on the significance of the dynamic responses of the variables to the simulated shocks this allows conclusions to be drawn on the persistence of shocks results suggest that output variation is largely determined by aggregate demand shocks over the business cycle frequency importantly evidence is also found of rigidities in the form of price inertia and nominal wage stickiness

recovery rates default probabilities and the credit cycle in recessions the number of defaulting firms rises on top of this the average amount recovered on the bonds of defaulting firms tends to decrease this paper proposes an econometric model in which this joint time variation in default rates and recovery rate distributions is driven by an unobserved markov chain which we interpret as the credit cycle this model is shown to fit better than models in which this joint time variation is driven by observed macroeconomic variables we use the model to quantitatively assess the importance of allowing for systematic time variation in recovery rates which is often ignored in risk management and pricing models

business cycles in developing countries are they different abstract this paper demonstrates that developing countries differ considerably from their developed counterparts when focus is on the nature and characteristics of short run macroeconomic fluctuations cycles are generally shorter and the stylized facts of business cycles across countries are more diverse than those of the rather uniform industrialized countries supply side models are generally superior in explaining changes in output but a one size fits all approach in formulating policy is inappropriate our results also illustrate the critical importance of understanding business regularities as a stepping stone in the process of designing appropriate stabilization policy and macroeconomic management in developing countries

a life cycle perspective on changes in earnings inequality among married men and women abstract the connection between changes in earnings inequality of individuals and changes in family earnings involves several links the movements in the employment of different family members the association between changes in husbands and in wives earnings and patterns of assortative mating a decomposition of the logarithm of the coefficient of variation in family earnings identifies these links the data on the dispersion of family earnings are organized not simply over time but also by age the growth in wives relative employment and earnings has partly offset the effects on family earnings inequality of the increase in husbands earnings inequality

international real business cycles we ask whether a two country real business cycle model can account simultaneously for domestic and international aspects of business cycles with this question in mind we document a number of discrepancies between theory and data the most striking discrepancy concerns the correlations of consumption and output across countries in the data outputs are generally more highly correlated across countries than consumptions in the model we see the opposite
