optimal bank capital this article reports estimates of the long run costs and benefits of having banks fund more of their assets with loss absorbing capital or equity we model how shifts in funding affect required rates of return and how costs are influenced by the tax system we draw a clear distinction between costs to individual institutions private costs and overall economic or social costs we find that the amount of equity capital that is likely to be desirable for banks to use is very much larger than banks have used in recent years and also higher than targets agreed under the basel iii framework this article reports estimates of the long run costs and benefits of having banks fund more of their assets with loss absorbing capital by which we mean equity rather than debt the benefits come because a larger buffer of truly loss absorbing capital reduces the chance of banking crises which as both past history and recent events show generate substantial economic costs the offset to any such benefits comes in the form of potentially higher costs of intermediation of saving through the banking system the cost of funding bank lending might rise as equity replaces debt and such costs can be expected to be reflected in a higher interest rate charged to those who borrow from banks that in turn would tend to reduce the level of investment with potentially long lasting effects on the level of economic activity calibrating the size of these costs and benefits is important but far from

european schemes for promoting renewables in liberalised markets abstract the paper describes possibilities and problems for penetration of supply systems based on renewable energy sources in liberalised markets the analysis is based on recent development in eu with different models for support of installations based on renewable energy these include feed in models with guaranteed minimum tariffs tender models for different bands of technologies and green certificates trading models with obligatory consumer quota the paper describes the market situation in selected european countries including germany the uk holland and denmark an eu directive from september 2001 has postponed the decision on a possible harmonisation of promotional models until at least 2005 in order to obtain more practical experience with the different support schemes a critical evaluation is given in this paper of the different models with proposals for a balanced development between environmental and trading concerns it is argued that too much emphasis is presently given to the side of free trade at the expense of long range planning for a sustainable energy development

mitigating the pro cyclicality of basel ii policy discussions on the recent financial crisis feature widespread calls to address the pro cyclical effects of regulation the main concern is that the new risk sensitive bank capital regulation basel ii may amplify business cycle fluctuations this paper compares the leading alternative procedures that have been proposed to mitigate this problem we estimate a model of the probabilities of default pds of spanish firms during the period 1987 2008 and use the estimated pds to compute the corresponding series of basel ii capital requirements per unit of loans these requirements move significantly along the business cycle ranging from 7 6 in 2006 to 11 9 in 1993 the comparison of the different procedures is based on the criterion of minimizing the root mean square deviations of each adjusted series with respect to the hodrick prescott trend of the original series the results show that the best procedures are either to smooth the input of the basel ii formula by using through the cycle pds or to smooth the output with a multiplier based on gdp growth our discussion concludes that the latter is better in terms of simplicity transparency and consistency with banks risk pricing and risk management systems for the portfolio of spanish commercial and industrial loans and a 45 loss given default lgd the multiplier would amount to a 6 5 surcharge for each standard deviation in gdp growth the surcharge would be significantly higher with cyclically varying lgds rafael repullo jesus saurina and carlos trucharte

dynamic factor models with macro frailty and industry effects for u s default counts the credit crisis of 2008 we develop a high dimensional nonlinear and non gaussian dynamic factor model for the decomposition of systematic default risk conditions into latent components for 1 macroeconomic financial risk 2 autonomous default dynamics frailty and 3 industry specific effects we analyze discrete u s corporate default counts together with macroeconomic and financial variables in one unifying framework we find that approximately 35 of default rate variation is due to systematic and industry factors approximately one third of this systematic variation is captured by the macroeconomic and financial factors the remainder is captured by frailty 40 and industry 25 effects the default specific effects are particularly relevant before and during times of financial turbulence we detect a build up of systematic risk over the period preceding the 2008 credit crisis this article has online supplementary material

the impact of regulation on bank equity infusions abstract this article examines the extent to which regulatory capital standards influence infusions of external equity into commercial banks while such infusions occur infrequently they result in large adjustments to overall bank capital and provide important signals to regulators of managerial intent using a sample of 753 equity capital issues occurring during 1986 and 1987 we find evidence that regulatory minimum capital constraints are instrumental in influencing the financing decisions made by a significant subset of banks

time variation in the dynamics of worker flows evidence from north america and europe vector autoregressive methods have been used to model the interrelationships between job vacancy rates job separation rates and job finding rates using tools such as impulse response analysis we investigate whether such impulse responses change across the business cycle or over time by estimating time varying parameter vector autoregressions for data from north america the usa and canada and europe france spain and the uk while the adjustment process of the labour market to shocks in canada and the usa is similar we find the adjustment process differs much more across the european countries with greater persistence in shocks relative to the usa and canada

dynamics of worker flows and vacancies evidence from the sign restriction approach this paper establishes robust dynamic features of the worker reallocation process in the us labor market i use structural vars with sign restrictions which take the form of restricting the short run negative relationship between vacancies and unemployment i e beveridge curve despite the weakness of these restrictions they reveal a clear unambiguous pattern that when unemployment increases and vacancies drop i both the separation rate and gross separations rise quickly and remain persistently high ii the job finding rate and vacancies drop in a hump shaped manner and iii gross hires respond little initially but eventually rise these results point to the importance of job loss in understanding us labor market dynamics this pattern also holds with respect to different kinds of shocks that induce the same beveridge curve relationship this paper also considers the disaggregate model which uses data disaggregated into six demographic groups and incorporates transitions into and out of the labor force i show that the separation rate continues to play a dominant role among prime age male workers while for other groups changes in the job finding rate are more important copyright 2009 john wiley sons ltd

bayesian dynamic factor models and portfolio allocation we discuss the development of dynamic factor models for multivariate financial time series and the incorporation of stochastic volatility components for latent factor processes bayesian inference and computation is developed and explored in a study of the dynamic factor structure of daily spot exchange rates for a selection of international currencies the models are direct generalizations of univariate stochastic volatility models and represent specific varieties of models recently discussed in the growing multivariate stochastic volatility literature we discuss model fitting based on retrospective data and sequential analysis for forward filtering and short term forecasting analyses are compared with results from the much simpler method of dynamic variance matrix discounting that for over a decade has been a standard approach in applied financial econometrics we study these models in analysis forecasting and sequential portfolio allocation for a selected set of international exchange rate retur

employment fluctuations in u s regions and industries the roles of national region specific and industry specific shocks this study quantifies the roles of national region specific and industry specific shocks in aggregate employment fluctuations in u s regions and industries variation among the growth rates of major regions and industries is decomposed into unobserved national region and industry specific components the results reject the view that any heterogeneity in regional fluctuations is attributable to differences in industry composition after controlling for industry mix effects roughly 40 of the variance of the cyclical innovation in any region s growth rate is particular to that region in addition region specific shocks appear to propagate across regions over time

global business cycles convergence or decoupling we analyze the evolution of the degree of global cyclical interdependence over the period 1960 2008 using a dynamic factor model we decompose macroeconomic fluctuations in output consumption and investment into a global factor factors specific to country groups and country specific factors we find that during 1985 2008 there is some convergence of business cycle fluctuations among industrial economies and among emerging market economies surprisingly there is a concomitant decline in the relative importance of the global factor we conclude that there is evidence of business cycle convergence within each of these two groups of countries but divergence or decoupling between them

asymmetric volatility spillovers between uk regional worker flows and vacancies this paper investigates volatility spillovers between uk regional job finding job separation and vacancy rates employing a large bayesian logistic smooth transition vector autoregression var model we find high volatility spillovers between uk regional labour markets analyses of net spillovers show that in general shocks to job separation rates tend to spread into job finding and vacancy rates while vacancy rates are usually at the receiving end of shocks transmitted from the job separations and job findings to shed further light on the shock propagation mechanism we also look into more detailed matters such as the differences in spillovers between regions within the same regime and that of the same region but in different regimes

international business cycles world region and country specific factors the paper investigates the common dynamic properties of business cycle fluctuations across countries regions and the world we employ a bayesian dynamic latent factor model to estimate common components in macroeconomic aggregates output consumption and investment in a 60 country sample covering seven regions of the world the results indicate that a common world factor is an important source of volatility for aggregates in most countries providing evidence for a world business cycle we find that region specific factors play only a minor role in explaining fluctuations in economic activity we also document similarities and differences across regions countries and aggregates jel f41 e32 c11 c32

the cyclical behaviour of european bank capital buffers using an unbalanced panel of accounting data from 1997 to 2004 and controlling for individual bank costs and risk we find capital buffers of the banks in the eu15 have a significant negative co movement with the cycle for banks in the accession countries there is significant positive co movement capital buffers of commercial and savings banks and of large banks exhibit negative co movement those of co operative and smaller banks exhibit positive co movement speeds of adjustment are fairly slow we interpret these results and discuss policy implications noting that negative co movement of capital buffers will exacerbate the pro cyclical impact of basel ii

deregulation and bank financial policy the standard view that banks can value maximize by exploiting non risk rated deposit insurance ignores the potential loss of a valuable bank charter due to insolvency recognition of this effect changes the bank s optimal financial policy and can induce extreme risk averting as well as risk taking behavior however as the value of the bank charter falls the risk taking strategy is more apt to dominate therefore current deregulation of the banking industry by easing entry and devaluing charters holds the potential for increases in the incidence of insolvency unless offsetting policies are instituted

capital requirements and the behaviour of commercial banks abstract i study the consequences of capital regulations on the portfolio choices of commercial banks elaborating on previous work by kareken and wallace 1978 koehn and santomero 1980 and kim and santomero 1988 i obtain the following results if the objective of commercial banks is maximization of the market value of their future profits value maximizing banks capital regulations cannot prevent banks from choosing very specialized and very risky portfolios risk based insurance premia are in fact the relevant instrument for that purpose on the other hand if banks behave as portfolio managers utility maximizing banks capital regulations can be effective but only if the weights used in the computation of the ratio are proportional to the systematic risks of the assets their betas because of limited liability of commercial banks a minimum capital regulation or a closing rule may become necessary as well to prevent failing banks from betting for resurrection

capital requirements and bank behavior in the uk are there lessons for international capital standards abstract the financial crisis prompted widespread interest in developing a better understanding of how capital regulation drives bank behavior this paper uses a unique comprehensive database of regulatory capital requirements on all uk banks to examine their effects on capital lending and balance sheet management behavior we find that capital requirements that include firm specific time varying add ons set by supervisors affect banks desired capital ratios and that resulting adjustments to capital and lending depend on the gap between actual and target ratios we use these results to measure the effects of a capital regime that includes features similar to those embedded in the uk framework our results suggest that countercyclical capital requirements may be less effective in slowing credit activity when banks can readily satisfy them with lower quality lower costing capital elements versus higher quality common equity given the size of the uk banking sector and the global nature of many of the largest institutions in the uk banking sector the results have implications for the ongoing debate surrounding the design and calibration of international capital standards

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

charter value minimum bank capital requirement and deposit insurance pricing in equilibrium abstract this paper shows that leaving insolvent banks with large enough charter values open can be optimal and derives normative bank closure reorganization policies based on the liquidation value of assets and the charter value the charter value of a bank is broadly defined as the value that would be foregone due to a closure our simulations of risk taking show that an optimal forbearance for an insolvent bank with a large enough charter value alleviates the moral hazard problem this is because increasing the risk raises the probability of losing the charter value although it generates a moral hazard gain

canadian labour market performance in international perspective my objective is to assess canadian labour market outcomes in recent decades and to compare canada s performance with that experienced in other industrialized countries the focus is on three key dimensions employment unemployment and the structure of earnings although my main purpose in the paper is to examine the canadian record i also ask what we can learn from canada s experience about the causes of some of the salient economic developments in oecd countries the rise and persistence of unemployment in europe and the growth of income inequality in countries such as the united states the united kingdom canada and australia let s begin with the question how well has the canadian economy performed during the past three decades if our reference point is the 1950s and 1960s the answer is likely to be poorly indeed the first twenty five years following the second world war now appear as a golden era since that period real income growth has been slow earnings have become more unequally distributed and unemployment has trended upward reaching levels that would have been considered outside the range of plausibility in the 1960s however most of the advanced countries have experienced a sharp deterioration in their economic performance since the early 1970s the turbulent world economic environment has made it difficult to sustain the kind of outcomes ob

sectoral shocks and metropolitan employment growth abstract in this paper we study the sources of industry employment growth in each of five metropolitan statistical areas msas the objective is to understand the relative importance of aggregate disturbances versus local sectoral shocks in generating observed employment fluctuations at the msa level the empirical evidence presented in this paper derives from structural vector autoregressions svars estimated for each of the five msas estimations use monthly employment data covering nine one digit industrial categories for the period 1951 1 1999 8 as well as two variables that capture the influences of aggregate i e national shocks on msas we find that within msa industry shocks explain considerably more of the forecast error variance in industry employment growth than do aggregate shocks sectoral shocks account for between 87 and 94 of the 36 month ahead forecast error variance among individual local sectors shocks to msa specific government manufacturing and service sector employment growth are the predominate sources of variability

why basel ii may need a leverage ratio restriction abstract we analyze regulatory capital requirements where the amount of required capital depends on the level of risk reported by the banks it is shown that if the supervisors have a limited ability to identify or to sanction dishonest banks an additional risk independent leverage ratio restriction may be necessary to induce truthful risk reporting the leverage ratio helps to offset the banks potential capital savings of understating their risks by i reducing banks put option value of limited liability ex ante and by ii increasing the banks net worth which in turn enhances the supervisors ability to sanction banks ex post

a new look at variation in employment growth in canada the role of industry provincial national and external factors we examine fluctuations in employment growth using canadian data from 1976 to 2010 we consider a wide range of models and examine the sensitivity of our findings to modelling assumptions the results from our most preferred model which we selected using the bayesian information criteria indicate that most of the variance in employment growth that is not due to the idiosyncratic error comes from domestic sources with most of this coming from industry and provincial factors overall we find that external and national factors play a much smaller role in employment fluctuations than in earlier research we provide some possible explanations for these differences and discuss the implications of our findings for public policy and theory

sectoral versus aggregate shocks a structural factor analysis of industrial production using factor methods we decompose industrial production ip into components arising from aggregate and sector specific shocks an approximate factor model finds that nearly all of ip variability is associated with common factors we then use a multisector growth model to adjust for the effects of input output linkages in the factor analysis thus a structural factor analysis indicates that the great moderation was characterized by a fall in the importance of aggregate shocks while the volatility of sectoral shocks was essentially unchanged consequently the role of idiosyncratic shocks increased considerably after the mid 1980s explaining half of the quarterly variation in ip

are bank capital ratios pro cyclical new evidence and perspectives this paper analyses how the new basel iii leverage ratio and risk weighted regulatory capital ratio behave over the cycle the analysis proposes a set up to test for the cyclical properties of bank capital ratios taking into account structural shifts in banks behaviour during the global financial crisis and its aftermath using a large data set covering international banks headquartered in 14 advanced economies for the period 1994 2012 we find that the basel iii leverage ratio is significantly more countercyclical than the risk weighted regulatory capital ratio it is a tighter constraint for banks in booms and a looser constraint in recessions

variation in employment growth in canada the role of external national regional and industrial factors this article investigates the effect of external national and sectoral shocks on canadian employment fluctuations at the national industrial and provincial levels we assume that employment growth in each industry province pair depends on u s growth lagged canadian growth at the national industrial and provincial levels an aggregate shock and shocks specific to each industry province and industry province pair we estimate that the u s and canadian shocks account for two thirds and a quarter respectively of aggregate variation sectoral shocks account for only one tenth of aggregate variation but represent 30 of the variation from canadian sources
