what drives deregulation economics and politics of the relaxation of bank branching restrictions this paper investigates private interest public interest and political institutional theories of regulatory change to analyze state level deregulation of bank branching restrictions using a hazard model we find that interest group factors related to the relative strength of potential winners large banks and small bank dependent firms and losers small banks and the rival insurance firms can explain the timing of branching deregulation across states during the last quarter century the same factors also explain congressional voting on interstate branching deregulation while we find some support for each theory the private interest approach provides the most compelling overall explanation of our results

oil price cycles and wavelets abstract the present paper addresses the question of the oil price macroeconomy relationship using world data and a time scale decomposition based on the theory of wavelets our approach is based on a global indicator the morgan stanley capital international msci index for the world and on the new framework offered by wavelets to analyse the oil price cycles and to investigate the oil price msci relationship this original approach enables us to identify that the cycles which contribute the most to oil price variations are 20 to 40 years cycles which correspond to the size of kuznets infrastructure cycles and probably represent energy investment cycles this wavelet decomposition also provides additional evidence to the reverse causality theory

the effects of regulatory policies on the cost of debt for electric utilities an empirical investigation this article develops a model of debt cost determination for regulated electric utilities based on an application of finance theory estimation of the model allows the hypothesis that regulatory policy directly influences the cost of debt to be tested and also enables the specific effects attributable to individual regulatory policy variables to be examined regulatory decisions are found to have statistically and economically significant effects on the cost of debt for electric utilities and the most important effects are associated with the treatment of construction work in progress for ratemaking purposes the extent of regulatory delay and whether or not interim rate relief is provided copyright 1989 by the university of chicago

the role of energy in productivity growth the objective of this paper is to analyze the role of energy in the growth of productivity the special significance of energy in economic growth was first established in the classic study energy and the american economy 1850 1975 by sam schurr and his associates 1960 at resources for the future for the period from 1920 to 1955 schurr noted that energy intensity of production had fallen while both labor and total factor productivity were rising the simultaneous decline in energy intensity and labor intensity of production ruled out the possibility of explaining the growth of productivity solely on the basis of substitution of less expensive energy for more expensive labor since the quantity of both energy and labor inputs required for a given level of output had been reduced technical change is also a critical explanatory factor an alternative explanation for growth of output with declining energy and labor intensity required an examination of the character of technical change this examination was motivated by the fact that from 1920 to 1955 the utilization of electricity had expanded by a factor of more than ten while consumption of all other forms of energy only doubled the two key features of technical change during this period were that the thermal efficiency of conversion of fuels into electricity increased by a factor of three and that the unusual characteristics of electricity had made it possible to perform tasks in altogether different ways than if the fuels had to be used directly schurr 1983 p 3 schurr 1982 has recently extended the analysis of energy and the american economy through 1981 for the period through 1969 his conclusions are as follows although the inverse relationship between total factor productivity and energy intensity virtually disappeared during the 1953 1969 period it is still noteworthy that high rates of improvement in total factor productivity were essentially not associated with increases in energy intensity 1982 p 6 schurr 1982 has analyzed the experience of the u s economy in the aftermath of the oil embargo of 1973 he points out that energy intensity of production has fallen steadily since 1973 and that the rate of decline accelerated sharply after the second oil price shock in 1979 following the iranian revolution he goes on to point out that

frameworks for analyzing the effects of risk and environmental regulations on productivity three separate effects of regulatory policies on enterprise decisions can be distinguished first increased regulatory penalties will diminish output and profits in static models or equivalently in multiperiod models in which investments are completely reversible as is well known second if investment commitments are irreversible there will be an additional effect of a known schedule of changes in the regulatory policy which will depress output even further finally the addition of uncertainty with regard to regulatory policy produces a third effect resulting in expected opportunity losses for firms both output and quality investments will be depressed by regulatory policy lotteries regulations influence current enterprise decisions not only through their current level but through their expected future level and the degree of uncertainty regarding these future regulatory policies 9 references 1 figure

environmental regulation technological innovation and energy consumption a cross region analysis in china abstract china has encountered the environmental issues and energy pressures in the middle income stage strengthening environmental regulation is a crucial measure to prevent environment deterioration and energy dilemma this paper investigates the three types of environmental regulations on energy consumption using feasible generalized least squares method during 1997 2015 in direct and indirect path the main conclusions are as follows in the direct path the economical and supervised types of environmental regulations have inhibited energy consumption whilst legal environmental regulation has no significant impact as for indirect path the rebound effect of energy is greater than the energy conservation generated by technological innovation which is embodied as an inhibitory effect the effects of environmental regulation display regional difference the legal and supervised types of environmental regulations have significant cost effect and rebound effect on energy consumption in the entire samples on the contrary the economical environmental regulation shows the opposite sigh in eastern regions the counterfactual simulation results show that the net effects of environmental regulations on energy consumption are negative which is beneficial for relieving energy pressures based on the findings this paper provides pertinent policy implications

plant vintage technology and environmental regulation abstract we use data on productivity and pollution abatement costs at individual pulp and paper mills to test whether the impact of environmental regulation on productivity differs by plant vintage and technology plants with higher pollution abatement costs have significantly lower productivity levels this relationship differs greatly based on a plant s technology with productivity at integrated mills being greatly affected by abatement costs while the impact at non integrated mills is negligible plant vintage does not seem to matter with older and newer plants showing similar impacts reported abatement costs appear to substantially understate the true costs of abatement accounting for the impact of technology differences makes some difference in the estimated overall impact of environmental regulation

the finance growth nexus evidence from bank branch deregulation this paper provides evidence that financial markets can directly affect economic growth by studying the relaxation of bank branch restrictions in the united states we find that the rates of real per capita growth in income and output increase significantly following intrastate branch reform we also argue that the observed changes in growth are the result of changes in the banking system improvements in the quality of bank lending not increased volume of bank lending appear to be responsible for faster growth

corruption in america abstract we use a data set of federal corruption convictions in the u s to investigate the causes and consequences of corruption more educated states and to a smaller degree richer states have less corruption this relationship holds even when we use historical factors like congregationalism in 1890 as an instrument for the level of schooling today the level of corruption is also correlated with the level of income inequality and racial fractionalization and uncorrelated with the size of government there is a weak negative relationship between corruption and economic development in a state these results echo the cross country findings and support the view that the correlation between development and good political outcomes occurs because education improves political institutions

does oil move equity prices a global view many studies indicate that oil price shocks have an adverse effect on real output and hence an adverse effect on corporate profits where oil is used as a key input the present study examines whether and to what extent the adverse effect of oil price shocks impacts stock market returns to this end we analyse 35 datastream global industry indices for the period from april 1983 to september 2005 our findings indicate that oil price rises have a negative impact on equity returns for all sectors except mining and oil and gas industries generally these results are consistent with economic theory and evidence provided by previous empirical studies little evidence of any asymmetry is detected in the oil price sensitivities in light of our findings we recommend that international portfolio investors consider hedging oil price risk

the effect of clean water regulation on profitability testing the porter hypothesis previous theoretical research provides opposing arguments regarding the effect of environmental regulation on profitability this study provides empirical evidence on this debated effect by testing the strong version of the porter hypothesis we employ panel data analysis to examine the effect of water regulation as measured by permitted wastewater discharge limits on the profitability of publicly held firms operating within the chemical manufacturing industries we find that tighter water regulation meaningfully lowers profitability by reinterpreting profitability in terms of sales and costs the results demonstrate that tighter water regulation increases costs conditioned on a given level of sales

volatility spillovers between oil prices and stock sector returns implications for portfolio management abstract in this article we take a recent generalized var garch approach to examine the extent of volatility transmission between oil and stock markets in europe and the united states at the sector level the empirical model is advantageous in that it typically allows simultaneous shock transmission in the conditional returns and volatilities insofar as volatility transmission across oil and stock sector markets is a crucial element for portfolio designs and risk management we also analyze the optimal weights and hedge ratios for oil stock portfolio holdings with respect to the results our findings point to the existence of significant volatility spillover between oil and sector stock returns however the spillover is usually unidirectional from oil markets to stock markets in europe but bidirectional in the united states our back testing procedures finally suggest that taking the cross market volatility spillovers estimated from the var garch models often leads to diversification benefits and hedging effectiveness better than those of commonly used multivariate volatility models such as the ccc garch of bollerslev 1990 the diagonal bekk garch of engle and kroner 1995 and the dcc garch of engle 2002

surprised or not surprised the investors reaction to the comprehensive assessment preceding the launch of the banking union abstract did the comprehensive assessment ca preceding the single supervisory mechanism ssm launch in europe achieve its aims of producing new valuable information for the market we show that the ca achieved the goal of increasing transparency investors were able to detect weak banks at the announcement of the procedure 23rd october 2013 but gained full information on the amount of the capital shortfall only at the disclosure of the results 26th october 2014 furthermore at the official launch of the ssm 4th november 2014 banks under direct european central bank ecb supervision registered a more negative market reaction with respect to banks maintaining their national supervisors using a regression model including possible confounders and allowing for treatment effect heterogeneity this negative reaction is confirmed these findings suggest that at least in the short run investors penalized banks subject to direct ecb supervision probably because of the fear of regulatory inconsistencies

public regulations and the slowdown in productivity growth a time series regression model of the us manufacturing sector is developed to estimate the direct and indirect relationships of public regulations and productivity for the 1973 to 1977 period preliminary results show that 12 to 21 of the productivity slowdown is blamed on regulation other contributing factors are a reduced non labor to labor input 15 average cyclical impact 0 to 15 and a combination of changes in labor composition expenses for research and development and shifts in sectoral output the study focuses on measured productivity and the results have little implication to true productivity growth 14 references 24 tables dck

bailouts sovereign risk and bank portfolio choices abstract i study the role of sovereign risk in determining the effects of expected bailouts on banks portfolio decisions empirically data on italian banks show that they decrease lending to firms and increase purchases of government bonds following an increase in the probability of a bailout if the risk of sovereign default is sufficiently low crucially the portfolio adjustment becomes weaker and eventually reverses sign as sovereign risk increases to interpret these results i develop a model in which the relation between the bailout probability and the corresponding payoff to bank owners bailout rents depends on sovereign risk the model s predictions are consistent with the key features of the data

zombie lending and depressed restructuring in japan this paper explores the role that misdirected bank lending played in prolonging the japanese macroeconomic stagnation that began in the early 1990s the investigation focuses on the wide spread practice of japanese banks of continuing to lend to otherwise insolvent firms we docu ment the prevalence of this forbearance lending and show its distorting effects on healthy firms that were competing with the impaired firms the paper by hoshi 2000 was the first to call attention to this phenomenon and its ramifi

on environmental federalism and direct emission control abstract a theoretical exception to the race to the bottom contends that if decentralized environmental policy is comprised of direct controls on each firm emissions standards are set too high when compared to a centralized optimum herein we examine potential distortions in decentralized decision making by reconciling two recent views of direct environmental controls we show that differences in direct control policy can arise from differences in the number of symmetric jurisdictions in an economy our results suggest the race is on once the number of jurisdictions competing for a fixed number of firms increase we see the race is off when few jurisdictions can exploit their form of environmental market power

environmental regulations and productivity growth the case of fossil fueled electric power generation this paper measures and analyzes the effect of sulfur dioxide emission restrictions on the rate of productivity growth in the electric power industry over the 1973 79 business cycle a firm specific measure of regulatory intensity is developed which depends on the severity of the emission standard the extent of enforcement and the unconstrained emission rate relevant to each utility the results indicate that emission regulations result in significantly higher generating costs primarily from the increased use of low sulfur fuels the average rate of productivity growth was reduced by 0 59 percentage points per year for constrained utilities

wavelet dynamics for oil stock world interactions abstract a previous research ignores the distinction between short term and long term and by decomposing financial variables world general and stock market indexes and the macroeconomic variable oil prices at various time scales we study the relationship among series on a daily scale by scale basis continuous time wavelets help to circumvent the problems associated to basic linear regressions and given that stock oil relationships are usually described as complicated we extend previous findings by providing more generalized and convincing results in analyzing contagion and interdependence issues as well as lead and lag effects for both world general and sector stock levels between december 1992 and october 2012 the relationship between oil prices and sector stock returns is ambiguous because results seem to show that there are both phase and anti phase relationships where mostly it is oil that is the lagging variable independently of the sector under analysis there is higher coherence among series for higher scales thus supporting the interdependence hypothesis showing that long run market dynamics are more uncertain empirical results indicate a bidirectional relationship between both series for large time horizons which can be associated to fundamentalist traders especially fund managers and institutional investors and which depend on the historical period under analysis

environmental protection and economic growth what do the residuals tell us conventional wisdom implies economic growth and environmental quality are incompatible policy objectives recent empirical evidence however suggests stringency of environmental regulations are only weakly or not at all associated with decreased manufacturing activity this paper uses more recent 1982 1994 state level panel data to test if environmental regulations affect manufacturing employment estimation results from our three stage sample selection panel data model suggest that state environmental regulations adversely affect job growth in three of the four industries analyzed

a complete characterization of optimal growth paths in an aggregated model with a non concave production function the convexity of technology has played a crucial role in economic analyses of optimal one sector growth problems for example two of the key results on the traditional model of ramsey 1928 that have relied on the convexity of the technology are that optimal intertemporal growth involves moving monotonically towards a unique steady state as in cass 1965 koopmans 1965 and that the value function is a concave differentiable function of the initial capital stock as in benveniste and scheinkman 1979

insider trading in supervised industries abstractwe investigate the impact of government agency oversight such as by the federal reserve on insider trading at the firm level regulatory supervision potentially limits trading based on material nonpublic information as it provides another layer of corporate governance to mitigate outflows of private information yet regulators themselves may serve as a source of information leakage thereby facilitating insider trading activity we find first that in comparison to nonsupervised firms supervised firms exhibit substantially greater trading based on inside information prior to earnings announcements second in the first few days after firms provide private information to regulators or when regulators possess private information inaccessible to corporate insiders these firms exhibit greater symptoms of insider trading finally within a given supervised industry insider trading symptoms appear more pronounced when regulators exhibit greater leniency or operate in states with more political c

separation of regulators against collusive behavior we show that the separation of powers in regulation may act as a commitment against the threat of regulatory capture splitting regulatory tasks and monitoring technologies among several nonbenevolent regulators may reduce their discretion in engaging in socially wasteful activities when regulators make collusive offers that are accepted by the agent whatever his characteristics competition between regulators relaxes collusion proofness constraints and improves social welfare this result is robust to different specifications of the agent s preferences and to the timing of the game as long as one insists on safe side contracting offers we also discuss how separation affects both allocative efficiency and the distribution of rents in the economy

reexamining the empirical evidence for an environmental kuznets curve this paper uses an updated and revised panel data set on ambient air pollution in cities worldwide to examine the robustness of the evidence for the existence of an inverted u shaped relationship between national income and pollution we test the sensitivity of the pollution income relationship to functional forms to additional covariates and to changes in the nations cities and years sampled we find that the results are highly sensitive to these changes and conclude that there is little empirical support for an inverted u shaped relationship between several important air pollutants and national income in these data

time varying volatility spillover between chinese fuel oil and stock index futures markets based on a dcc garch model with a semi nonparametric approach abstract this paper reveals some new evidence on the volatility spillover between fuel oil and stock index futures markets in china by considering its time variant feature time varying effect is specified by the legendre polynomials in a dcc garch model moreover the semi nonparametric snp approach accounting for marginal excess kurtosis and asymmetry is applied we find different time evolving patterns of volatility spillover across multiple periods due to the structural breaks the direction of mean volatility spillover is found to be bilateral moreover the strength of mean volatility spillover shows that the effect from stock index to fuel oil futures is much stronger than the other way around this implies that the stock index futures market plays a leading role in information processing these findings have important implications for the fuel oil stakeholders as well as risk management

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource productivity

drivers of systemic risk do national and european perspectives differ abstract with the establishment of the banking union the european central bank has been granted the power to impose stricter regulations than the national regulator if systemic risks are not adequately addressed at the national level we ask whether there is a cross border externality in the sense that a bank s systemic risk differs when applying a national versus a european perspective on average banks contribution to systemic risk is similar at the two regional levels and so is the ranking of banks generally larger banks and banks with a lower share of loans are more systemically important the effects of these variables are qualitatively but not quantitatively similar at the national versus the european level

a two sector model of endogenous growth with leisure in this paper we analyze a class of endogenous growth models with physical and human capital and with three altematives uses of time unqualified leisure work and education in contrast to some other related models we find that even in the absence of technological extemalities there could be multiple balanced paths we provide a characterization of the qualitative behavior of consumption leisure work and education over those balanced paths and study their transitional dynamics

endogenous matching and the empirical determinants of contract form empirical work on contracts typically regresses contract choice on observed principal and agent characteristics if i some of these characteristics are unobserved or partially observed and ii there are incentives whereby particular types of agents end up contracting with particular types of principals estimated coefficients on the observed characteristics may be misleading we address this endogenous matching problem using a data set on agricultural contracts between landlords and tenants in early renaissance tuscany controlling for endogenous matching has an impact on parameters of interest and tenants risk aversion appears to have influenced contract choice

the revolving door and worker flows in banking regulation abstract this paper traces career transitions of federal and state u s banking regulators from a large sample of publicly available curricula vitae and provides basic facts on worker flows between the regulatory and private sector resulting from the revolving door we find strong countercyclical net worker flows into regulatory jobs driven largely by higher gross outflows into the private sector during booms these worker flows are also driven by state specific banking conditions as measured by local banks profitability asset quality and failure rates the regulatory sector seems to experience a retention challenge over time with shorter regulatory spells for workers and especially those with higher education evidence from cross state enforcement actions of regulators shows gross inflows into regulation and gross outflows from regulation are both higher during periods of intense enforcement though gross outflows are significantly smaller in magnitude these results appear inconsistent with a quid pro quo explanation of the revolving door but consistent with a regulatory schooling hypothesis

capital investment strategies under uncertain regulation this article presents a positive model of investment choices by regulated firms that offers rational explanations for electric utilities recent behavior of delaying investment and choosing smaller shorter lead time technologies the model assumes thatfirms capital investments require long lead times during which the value of the completed project is uncertain firms anticipate regulatory profit and loss restrictions but expectations about the value of a completed project change over time firms decisions are modelled using an option pricing approach that incorporates the value of flexibility to delay or abandon projects the article shows why rational firms invest in smaller shorter lead time plants or delay investment when faced with uncertain and asymmetric profit and loss restrictions it also looks at decisions to abandon partially completed plants and shows that the static result that a higher cost allowance on abandoned projects increases the incentive for investment is not generally true in a dynamic model

what fuels the boom drives the bust regulation and the mortgage crisis the weakly regulated independent mortgage companies imcs had a vastly disproportional contribution to the expansion in risky credit during the mortgage boom and to the ensuing foreclosure crisis we exploit a quasi experimental setting created by the inconsistency of state lender regulations between banks and imcs and their heterogeneity across states to isolate the impact of regulation on lending standards using county pairs straddling state borders we find that weaker state regulation of imcs is associated with a sharper expansion of imcs particularly in risky high yield loans which were also of worse quality in the weakly regulated states based on subsequent delinquency

investment tax incentives prices and the supply of capital goods using data on the prices of capital goods this paper shows that much of the benefit of investment tax incentives does not go to investing firms but rather to capital suppliers through higher prices the reduction in the cost of capital from a 10 percent investment tax credit increases equipment prices 3 5 7 0 percent this lasts several years and is largest for assets with large order backlogs low import competition or with a large fraction of buyers able to use investment subsidies capital goods workers wages rise too instrumental variables estimates of the short run supply elasticity are around 1 and can explain the traditionally small estimates of investment demand elasticities in absolute value the demand elasticity implied here exceeds 1

the impact of environmental policy on international competitiveness in manufacturing the aim of this study is to test the hypothesis that environmental stringency adversely affects the international competitiveness net exports in manufacturing sectors the model follows the standard factor endowment approach to explain the effects of environmental regulatory policy on net exports in different product based industries an econometric model is constructed which includes factor endowments and environmental regulations to examine how strict environmental policies impact export competitiveness a panel dataset of 10 organisation for economic co operation and development oecd countries over 17 years 1987 2003 was constructed for the modelling effort the study finds that environmental regulations can be a way to combat the flight of manufacturing out of developed countries if the output from these industries can be identified as environmentally friendly a positive relationship between net exports and environmental regulations was found for paper products wood products and textile prod

investment banks as corporate monitors in the early twentieth century united states we study the effect of financial relationships on firms investment decisions and access to external finance in the early twentieth century securities underwriters commonly held directorships with american corporations section 10 of the clayton antitrust act prohibited bankers from serving on the boards of railroads for which they underwrote securities we find that following the implementation of section 10 railroads with strong preexisting relationships with underwriters saw declines in their investment rates valuations and leverage and increases in their costs of external funds reassuringly we do not observe similar effects among industrials and utilities which were not subject to section 10 our results are consistent with underwriters on corporate boards acting as delegated monitors and highlight the potential for regulations intended to address conflicts of interest to disrupt valuable information flows

credit induced boom and bust this paper exploits the federal preemption of national banks in 2004 from local laws against predatory lending to gauge the effect of the supply of credit on the real economy first the preemption regulation resulted in an 11 increase in annual lending in the 2004 2006 period which is associated with a 3 3 rise in annual house price growth rate and a 2 2 expansion of employment in nontradable sectors this was followed by a sharp decline in subsequent years furthermore we show that the increase in the supply of credit reduced delinquencies during boom years but increased them in bust years received june 7 2015 editorial decision december 22 2016 by editor robin greenwood

wavelet based test of co movement and causality between oil and renewable energy stock prices abstract we studied co movement and causality between oil and renewable energy stock prices using continuous and discrete wavelets firstly to obtain information on dynamic correlations over time and for different time scales from wavelet coherence and secondly to obtain information on linear and non linear granger causality in the time frequency domain for general and sectoral renewable energy indices for the period 2006 2015 our findings indicate that dependence between oil and renewable energy returns in the short run was weak but gradually strengthened towards the long run mainly for the period 2008 2012 our causality tests provide evidence against linear causality at higher frequencies and in favour of unidirectional and bidirectional linear causality at lower frequencies in contrast we found consistent evidence of non linear causality running from renewable energy indices to oil prices at different time horizons and mixed evidence of causality running from oil to renewable energy prices these results have potential implications for investors in terms of hedging and for policymakers in terms of policy support decisions regarding the development of renewable energy

regulation and corporate investment policy in a previous paper it was shown that the traditional rule that the allowed return on the equity of a regulated firm should be set equal to its cost of equity capital was conceptually deficient 2 this deficiency arises because the cost of equity capital of a regulated firm depends upon its risk which depends in turn upon the regulatory policy that will be followed in the future including the allowed rate of return it was argued therefore that this traditional rule should be replaced by the requirement that the regulatory policy be consistent a consistent regulatory policy achieves what the traditional rule only attempts it ensures that at the time of a regulatory hearing the market value of the firm equity is equal to the equity financed portion of the rate base to devise a consistent regulatory policy it is necessary to have a valuation model which takes explicit account of regulatory policy such a model was developed in the above mentioned paper in this paper we generalize the earlier valuation model so that the investment policy of the regulated firm is determined by the value maximizing decisions of the management instead of being taken as exogenous to the extent that investment policy is discretionary its endogeneity must be taken into account in devising a consistent regulatory policy and this is made possible by the generalized model in reality it seems unclear to what extent the investment policies of regulated firms are predetermined by the requirement that they meet demand and to what extent they are discretionary since the model presented here easily accommodates constraints on the investment policy it is the more appropriate model so long as there exists any element of discretionary investment behaviour and permits a more adequate approach to the determination of consistent regulatory policies with discretionary investment policy an important consequence of any particular consistent regulatory policy is the investment policy it induces in section 4 we show how the value maximizing investment policy is affected by the choice of regulatory policy on the other hand regulated firms are wont to argue that their investments are in the main predetermined by demand and must be undertaken regardless of their profitability this putative lack of discretion it is maintained means that the appropriate allowed rate of return is higher than would otherwise be the case in section 4 also we evaluate the strength of this consideration by comparing the allowed rate of return under consistent regulatory policies when investment policy is and is not discretionary section 5 shows briefly how the analysis can be extended to account for the effect of debt in the capital structure

oil price shocks and stock markets in the u s and 13 european countries abstract oil price shocks have a statistically significant impact on real stock returns contemporaneously and or within the following month in the u s and 13 european countries over 1986 1 2005 12 norway as an oil exporter shows a statistically significantly positive response of real stock returns to an oil price increase the median result from variance decomposition analysis is that oil price shocks account for a statistically significant 6 of the volatility in real stock returns for many european countries but not for the u s increased volatility of oil prices significantly depresses real stock returns the contribution of oil price shocks to variability in real stock returns in the u s and most other countries is greater than that of interest rate an increase in real oil price is associated with a significant increase in the short term interest rate in the u s and eight out of 13 european countries within one or two months counter to findings for the u s and for norway there is little evidence of asymmetric effects on real stock returns of positive and negative oil price shocks for oil importing european countries

wavelet decomposition and regime shifts assessing the effects of crude oil shocks on stock market returns while there is a large body of empirical studies on the relationship between crude oil price changes and stock market returns they have failed to achieve a consensus on this subject in this paper we combine wavelet analysis and markov switching vector autoregressive ms var approach to explore the impact of the crude oil co shocks on the stock market returns for uk france and japan over the period from january 1989 to december 2007 our procedure involves the estimation of the extended ms var model in order to investigate the importance of the resultant wavelet filtering series after removing random components in determining the behavior of the stock market volatilities we show that co shocks do not affect the recession stock market phases except for japan however they significantly reduce moderate and or expansion stock market phases temporarily moreover this negative relationship appears to be more pronounced during the pre 1999 period the empirical findings will prove extremely useful to investors who need to understand the exact effect of international oil changes on certain stocks prices as well as for policy managers who need a more thorough evaluation about the efficiency of hedging policies affected by oil price changes

on the dynamic links between commodities and islamic equity abstract this paper investigates whether commodities offer potential diversification benefits for islamic equity index investors in light of possible financialization of commodity markets using mgarch dcc and wavelet coherence analyses our findings reveal that correlations between commodity markets and the dow jones islamic market world index are time varying and highly volatile throughout the january 1999 april 2015 period a substantial and persistent increase was observed in the return correlations between commodities and islamic equity at the onset of the 2008 financial crisis however trends in the recent two years suggest that this association is heading towards its pre crisis levels offering again diversification benefits for islamic equity holders these benefits vary across different commodities in various time scales overall gold natural gas soft commodities grains and livestock are better portfolio diversifiers than oil and other metals relative to medium to long term investors short term investors less than 32 days horizon gained better diversification benefits in most commodities during bullish bearish and market recovery periods these findings have implications for investors who are heterogeneous in risk tolerance and time preference as well as for policymakers who are concerned with market stability

non convexities in continuous time investment theory that non convex preferences or technologies cause problems for economic theory is well known in recent years there have been numerous contributions to the nonconvexity problem in the context of models with a finite dimensional commodity space in the capital theory context non convexities have received explicit treatment in a few papers in two distinguishable ways the problem is cast either in a discrete time framework aoki 1971 rothschild 1971 or in a continuous time framework in which there are implicitly unbounded economies of scale in investment the latter formulation leads to jumps in the state variable or lumpy investment the standard problem treated is one of decreasing costs in the installation of new capacity contributions include chenery 1952 dixit mirrlees and stern 1975 hartwick 1976 manne 1967 srinivasan 1967 starrett 1978 and weitzman 1970 these types of analysis unfortunately ignore some of the most interesting problems associated with non convexities in investment theory in a discrete time framework the important distinction between stocks and flows is blurred while the capacity installation problem by admitting unbounded scale economies excludes the smoothing of state variables that follows by allowing for eventually increasing costs of adjustment in this paper we undertake a systematic examination of non convexities or sometimes non concavities in the context of a classic problem in continuous time investment theory the optimal accumulation of capital by a firm maximizing its present value over an infinite horizon while the results obtained are specific to this particular model we feel that they can be qualitatively extended to any capital theory problem which can be cast in a continuous time optimal control theory framework there are various sorts of non2 convexities which can arise in these problems first there can be either stock or flow non convexities that is non convexities which are introduced into the net benefit function the measure of the flow of benefits at each moment through changes in the capital stock state variable on the one hand or changes in the flow of investment control variable on the other if the benefit and transition functions are not concave in both these variables then necessary conditions are no longer sufficient for optimality and conventional marginal analysis fails non convexities can also be introduced into the value functional which has a stock dimension in order to examine these different sorts of non convexity problems we shall now present the basic economic problem a firm is faced with the problem of maximizing the present value of discounted cash flow over an infinite horizon hence it chooses an investment programme i t to maximize 00

crude oil and stock markets stability instability and bubbles abstract we analyze the long run relationship between the world price of crude oil and international stock markets over 1971 1 2008 3 using a cointegrated vector error correction model with additional regressors allowing for endogenously identified breaks in the cointegrating and error correction matrices we find evidence for breaks after 1980 5 1988 1 and 1999 9 there is a clear long run relationship between these series for six oecd countries for 1971 1 1980 5 and 1988 2 1999 9 suggesting that stock market indices respond negatively to increases in the oil price in the long run during 1980 6 1988 1 we find relationships that are not statistically significantly different from either zero or from the relationships of the previous period the expected negative long run relationship appears to disintegrate after 1999 9 this finding supports a conjecture of change in the relationship between real oil price and real stock prices in the last decade compared to earlier years which may suggest the presence of several stock market bubbles and or oil price bubbles since the turn of the century

separating bric using islamic stocks and crude oil dynamic conditional correlation and volatility spillover analysis abstract this paper explores the dynamic conditional correlation and volatility linkage between islamic indexes and oil for bric countries correlations between these assets increase during the global financial crisis for india and china but not for brazil and russia the volatility error forecast variance of all five indexes comes from spillover but is much lower compared to volatility spillover between conventional indexes and oil hedging performance of islamic indexes are superior in india and china compared to conventional indexes in emerging markets an optimal minimum variance portfolio without reducing expected return can be achieved by investing in lower weights of bric islamic indexes and oil compared to conventional indexes

is three a crowd competition among regulators in banking banks are able to switch among three options for a primary federal regulator the fdic the federal reserve and the occ we examine why they switch and what the results of switches are we find support for the hypothesis that competition among regulators has beneficial aspects regulators seem to specialize in offering banks that are changing strategy the ability to improve performance by switching regulators there is also evidence that the ability to switch regulators allows banks to get away from bank examiners who desire a quiet life that is examiners who attempt to minimize the effort they spend on work

the cost of regulation osha epa and the productivity slowdown the slowdown in productivity growth in the u s economy during the 1970 s has been a matter of great concern to policymakers associated as it is with inflation unemployment and declining real wage growth this paper examines the impact on productivity growth of government regulation specifically worker health and safety regulation by the occupational safety and health administration osha and environmental regulation by the environmental protection agency epa looking at data for 450 manufacturing industries between 1958 and 1978 the study finds a large negative relationship between such regulation and productivity growth using these results about 30 percent of the decline in productivity growth in manufacturing during the 1970 s may be attributed to such regulation several previous studies have looked at the contribution of regulation to the productivity slowdown many of these have inferred that the contribution must be small on the basis of the relatively small amount spent on complying with such regulations edward denison 1979 estimates that only about 16 percent of the productivity slowdown in the 1972 75 period was due to regulation 35 percentage points out of a slowdown of 2 17 percentage points paul portney 1981 notes that little of gnp is spent on pollution control under 2 percent concluding that therefore pollution regulations could have little effect on productivity growth norsworthy et al 1979 also find a small impact of pollution abatement capital expenditures on productivity growth studies based on econometric estimation of the regulation productivity relationship have found a wide range of results gregory christainsen and robert haveman 1981 find regulation reduced labor productivity growth by 27 percentage points using time series data and measures of total federal regulation robert crandall 1981 finds a strong relationship between pollution abatement capital and productivity growth but this relationship disappears when a measure of energy intensity is included robin siegel 1979 observes a significant contribution 5 percentage points from pollution control expenditures to the productivity slowdown for 1965 73 but not for later years finally frank gollop and mark roberts 1983 examine data for a set of electric utilities and find that regulation of emissions had a large impact on total factor productivity growth lowering it for regulated firms by 59 percentage points many other factors might help to explain the productivity slowdown including the rise in energy prices the long and severe recession and declines in research and development expenditures there have been a variety of studies examining the contributions of each factor to the slowdown they generally conclude that many factors contributed to the slowdown but that a sizable fraction of the slowdown remains unexplained by the estimated contributions of all the factors considered

inconsistent regulators evidence from banking we find that regulators can implement identical rules inconsistently due to differences in their institutional design and incentives and this behavior may adversely impact the effectiveness with which regulation is implemented we study supervisory decisions of u s banking regulators and exploit a legally determined rotation policy that assigns federal and state supervisors to the same bank at exogenously set time intervals comparing federal and state regulator supervisory ratings within the same bank we find that federal regulators are systematically tougher downgrading supervisory ratings almost twice as frequently as do state supervisors state regulators counteract these downgrades to some degree by upgrading more frequently under federal regulators banks report worse asset quality higher regulatory capital ratios and lower return on assets leniency of state regulators relative to their federal counterparts is related to costly outcomes such as higher failure rates and lower repayment rates of government assistance funds the discrepancy in regulator behavior is related to different weights given by regulators to local economic conditions and to some extent differences in regulatory resources we find no support for regulator self interest which includes revolving doors

exogenous oil supply shocks how big are they and how much do they matter for the u s economy abstract the paper proposes a new measure of exogenous oil supply shocks the timing the magnitude and the sign of this measure may differ greatly from current state of the art estimates it is shown that only a small fraction of the observed oil price increases during oil crisis periods can be attributed to exogenous oil production disruptions exogenous oil supply shocks cause a sharp drop of u s real gdp growth after five quarters rather than an immediate and sustained reduction in economic growth and a spike in cpi inflation after three quarters overall exogenous oil supply shocks made remarkably little difference for the evolution of the u s economy since the 1970s although they did matter for some historical episodes

the subsidiarity bias in regulation abstract we study the choice of the regulatory structure when a firm engages in different activities for different countries under decentralization regulatory contracts suffer from two opposite distortions the competition between regulatory authorities leads to too high powered contracts however with a dispersed ownership structure contracts tend to be too low powered for sufficiently substitutable activities decentralization always leads to an inefficient drift towards fixed price contracts nonetheless when regulators have private agendas and possess the discretion to distort their policy to gain the support of some interest groups decentralization may be preferred to centralization as competition between regulatory authorities mitigates their discretionary power

regulation and productivity performance the paper reviews theory and evidence on the ways in which regulation affects productivity outcomes in a context of endogenous growth it is argued that traditional measures of compliance costs miss the potentially most important impacts of regulation on productivity which occur through changes in incentives to invest and to innovate recent attempts to measure cross country variations in the strength of product market and employment regulation are considered and some weaknesses are highlighted nevertheless consistent with endogenous growth models there appears to he quite strong evidence that regulations which inhibit entry into product markets have an adverse effect on tfp growth in oecd countries although there are some discrepancies in the evidence on most measures the uk appears lightly regulated relative to france and germany and this may have contributed to a reduction in the recent past in the uk s tfp gap

financial consumer protection and the cost of financial intermediation evidence from advanced and developing economies using a data set of approximately 3 000 commercial banks from more than 100 countries i examine the impact of financial consumer protection policies on the cost of financial intermediation i find evidence that the existence of internal mechanisms for handling complaints requirements for fair treatment supervisory power related to consumer protection and various disclosure requirements reduce the cost of financial intermediation in advanced countries the results are different in the case of developing countries where i observe that most financial consumer protection policies increase the cost of intermediation suggesting that banks pass on regulatory burdens to their customers this paper was accepted by amit seru finance

equipment prices human capital and economic growth abstract this paper presents a multisectoral model of economic growth in which endogenous technological progress is embodied in new equipment capital the difference in the intensity of use of human capital across sectors creates aggregate dynamic non convexities and hence the model may generate multiple balanced growth paths under standard parameter values our model can explain the observed correlations found for a pool of countries between investment rates in equipment capital and income growth on the one hand and between the rate of decline in equipment prices and income growth on the other the model is then used to study the effectiveness of two public policies that have been widely implemented to promote economic growth an equipment investment tax credit and a tax incentive to human capital accumulation our results indicate that both policies have positive effects on equipment investment and on long run growth

islamic stocks conventional stocks and crude oil directional volatility spillover analysis in brics abstract this paper uses threshold garch tgarch and generalised forecast error variance decomposition to compute time domain and frequency domain volatility spillover the spillover technique is then applied to islamic and conventional stock indices and crude oil in brics countries brazil russia india china and south africa thus informing investors about the magnitude and speed of the volatility spillover we find that the total volatility spillover is driven mainly by a long term component accordingly these assets are suitable for investors with short and medium term investment horizons however analysis reveals that volatility spillover magnitude and speed increase substantially during the global financial crisis suggesting that investors in brazil russia and south africa with stocks in their portfolio should rebalance promptly dynamic covariance analysis shows that covariance between islamic and conventional stock index returns is the highest and exhibit a significant increase during the crisis period

the regulatory record of the greenspan fed alan greenspan played an important role in shaping major changes in the structure and rules of financial regulation indeed it is in this realm that chairman greenspan has made his most important contributions as an institutional innovator just describing how the federal reserve made possible the expansion of commercial banks powers to permit them to engage in investment banking could occupy this entire essay that change occurred in several stages beginning with the fed s decision in 1987 to allow small inroads by banks into investment banking those changes created a favorable track record which laid the groundwork for the administration s and congress s willingness to eliminate restrictions entirely in 1999 a policy the fed advocated in the 1990s the growth in commercial banks market share in investment banking has been dramatic in 1992 only 10 percent of corporate debt and less than 1 percent of corporate equity flotations were underwritten solely or jointly by commercial banks by 2002 that share had grown to 66 percent of debt and 36 percent of equity calomiris and thanavut pornrojnangkool 2006 can one identify a philosophy of regulation that underlies the regulatory advocacy of the fed under chairman greenspan although the fed s advocacy on various matters may appear somewhat contradictory or at least philosophically heterodox the fed has behaved in a manner that is remarkably predictable once one takes account of the political arena in which both regulatory and monetary policy are made there is fairly straightforward logic to the fed s regulatory advocacy to understand it one must consider the fed as a political player in the washington drama as a creature of congress subject to its oversight as a competitor with other regulators for influence within the financial services industry and within the political realm and as a prioritizing agent that had to decide which battles monetary or regulatory to fight when and how hard one lesson of this overview of fed regulatory advocacy during the greenspan years is that the algorithm of fed advocacy the decision process that decides which position the fed will advocate has not changed although some of the specific policy advocacy has john hawke 1988 wrote an evaluation of chairman paul volcker s regulatory policy during his years at the fed which was presented at the 1988 assa annual meeting and which describes an approach to fed policy that is similar to the one suggested here in that sense chairman greenspan did not change the fed indeed it is probably more accurate to say that his personal advocacy was changed by being at the fed but that does not imply an irrelevance to his leadership what emerges from a review of greenspan s regulatory record is an appreciation of his skill as a beltway warrior particularly with respect to his success in facilitating the geographical expansion of banks broadening bank powers and securing a prominent role for the fed under the gramm leach bliley act of 1999

is bank supervision central to central banking whether central banks should play an active role in bank supervision and regulation is being debated both in the united states and abroad while the bank of england has recently been stripped of its supervisory responsibilities and several proposals in the united states have advocated removing bank supervision from the federal reserve system other countries are considering enhancing central bank involvement in this area many of the arguments for and against these proposals hinge on the effect this change would have on the ability of the central bank to conduct monetary policy we find that confidential supervisory information on bank ratings significantly improves

a skeptical view of financialized corporate governance managerial compensation typically relies on financial yardsticks such as profits stock prices and return on equity to achieve alignment between the interests of managers and shareholders but financialized governance may not actually work well for most shareholders and even when it does significant tradeoffs and inefficiencies can arise from the conflict between maximizing financialized measures and society s broader interests effective governance requires that those in control are accountable for actions they take however those who control and benefit most from corporations success are often able to avoid accountability the history of corporate governance includes a parade of scandals and crises that have caused significant harm after each most key individuals tend to minimize their own culpability common claims from executives boards of directors auditors rating agencies politicians and regulators include we just didn t know we couldn t have predicted or it was just a few bad apples economists as well may react to corporate scandals and crises with their own version of we just didn t know as their models had ruled out certain possibilities effective governance of institutions in the private and public sectors should make it much more difficult for individuals in these institutions to get away with claiming that harm was out of their control when in reality they had encouraged or enabled harmful misconduct and ought to have taken action to prevent it

mortgage modification and strategic behavior evidence from a legal settlement with countrywide abstract we investigate whether homeowners respond strategically to news of mortgage modification programs we exploit plausibly exogenous variation in modification policy induced by settlement of us state government lawsuits against countrywide financial corporation which agreed to offer modifications to seriously delinquent borrowers using a difference in differences framework we find that countrywide s monthly delinquency rate increased more than 0 54 percentage points a 10 percent relative increase immediately after the settlement s announcement the estimated increase in default rates is largest among borrowers least likely to default otherwise these results suggest that strategic behavior should be an important consideration in designing mortgage modification programs jel d14 g21 k22 r31

the effect of state and local taxes on economic growth a time series cross section approach results based on pooled time series and cross section data are presented which indicate that state and local tax increases significantly retard economic growth when the revenue is used to fund transfer payments however when the revenue is used instead to finance improved public services such as education highways and public health and safety the favorable impact on location and production decisions provided by the enhanced services may more than counterbalance the disincentive effects of the associated taxes these findings underscore the importance of considering the incentives provided by a state s expenditures as well as by its taxes i n the past several years a number of states have implemented limitations on taxes or expenditures while others have raised tax rates in response to the revenue shortfalls of the early 1980s although much of the ongoing debate over state fiscal structures revolves around expressed preferences over tax expenditure combinations per se the question of how state and local taxes may affect economic growth is often central to the discussion nonetheless the empirical evidence remains sparse previous studies can be divided into two broad categories assessments of the magnitudes of tax costs and statistical analyses of the relationship between tax rates and growth cost studies have tended to minimize the role of taxes in business location decisions either because state and local taxes are a relatively small component of total costs for most businesses or because interstate tax differences are small relative to other cost differences between states although these results suggest that the role played by taxes is a minor one describing how large the tax disparities may be is not the same as ascertaining their economic effect of the statistical studies many including bloom 1955 thompson and mattila 1959 and carlton 1979 1983 find no relationship between taxes and growth however kleine 1977 grieson 1980 and generally grieson et al 1977 report negative correlations romans and subrahmanyam 1979 find growth to be negatively related to the fraction of revenues devoted to transfer payments and a variable which they claim measures personal tax progressivity but positively related to business taxes with the exception of carlton who estimates models of the birth and size of firms within metropolitan areas and the grieson et al 1977 and grieson 1980 studies which consider taxes in new york city and philadelphia these authors use data from a single cross section of states more recently newman 1983 and plaut and pluta 1983 both use cross sectional data from two time periods the former finding negative effects of corporate tax rates and the latter yielding mixed results in this study we utilize a time series from 1965 through 1979 of cross sections of 48 states exploiting the richness of this data set we are able to allow for otherwise unexplained differences between states which could be expected to bias results based on a single cross section moreover this much larger sample provides the statistical power necessary to disentangle the separate effects of different categories of taxes public expenditures and transfer payments a distinguishing feature of this paper is that we explicitly recognize the government budget constraint linking these fiscal variables and the deficit or surplus in addition we have taken account of the effects of labor force characteristics by including variables for wage rates unionization and population density our results indicate that tax increases significantly retard economic growth when the revenue is used to fund transfer payments as a result programs of income redistribution are more effectively undertaken at the federal than at the state and local level on the other hand when the revenue is received for publication april 30

the determinants of bank mergers a revealed preference analysis we provide new estimates of merger value creation by exploiting revealed preferences of merging banks within a matching market framework we find that merger value arises from cost efficiencies in overlapping markets relaxing of regulation and network effects exhibited by the acquirer target matching beyond our findings the revealed preference method has notable advantages that warrant its application beyond the bank merger market notably we show that the method outperforms reduced form alternatives out of sample enables sensible counterfactual experiments and can be used to evaluate private to private mergers which have been understudied because of lack of stock market data data as supplemental material are available at http dx doi org 10 1287 mnsc 2015 2245 this paper was accepted by amit seru finance

pricing for the clean air evidence from chinese housing market abstract air pollution is widely believed to cause healthy risks and influence nations economic dimensions this paper investigates the impact of air pollution on housing prices in china s 286 prefectural level cities during 2005 2013 to address the endogeneity problem of pm2 5 concentrations in our regression we propose an instrument variable strategy based on ventilation coefficient the estimation results suggest that a 10 increase in pm2 5 concentrations causes a 2 4 reduction in local housing prices air pollution also hinders the progress of urbanization limits cities human capital formation and changes people s expectations of housing prices that we interpret as three potential mechanisms behind our main findings

do structural oil market shocks affect stock prices abstract this paper investigates how explicit structural shocks that characterize the endogenous character of oil price changes affect stock market returns in a sample of eight countries australia canada france germany italy japan the united kingdom and the united states for each country the analysis proceeds in two steps first modifying the procedure of kilian kilian l forthcoming not all oil price shocks are alike disentangling demand and supply shocks in the crude oil market american economic review we employ a vector error correction or vector autoregressive model to decompose oil price changes into three components oil supply shocks global aggregate demand shocks and global oil demand shocks the last component relates to specific idiosyncratic features of the oil market such as changes in the precautionary demand concerning the uncertainty about the availability of future oil supplies second recovering the oil supply shocks global aggregate demand shocks and global oil demand shocks from the first analysis we then employ a vector autoregressive model to determine the effects of these structural shocks on the stock market returns in our sample of eight countries we find that international stock market returns do not respond in a large way to oil market shocks that is the significant effects that exist prove small in magnitude

renegotiation design with multiple regulators abstract one striking feature of the internal organization of governments is the existence of multiple regulators this paper explains this organizational choice as coming from the government s limited ability to commit the separation of powers between two regulators is modeled as a stackelberg common agency game with respect to the case of a single regulator the allocative efficiency and the regulated firm s informational rent are both reduced in the unique equilibrium of this game however when regulators have a limited ability to commit this static cost of regulators separation becomes a dynamic benefit separation makes renegotiation harder and improves commitment journal of economic literature classification numbers d82 l51

regulatory incentives and the thrift crisis dividends mutual to stock conversions and financial distress during the 1980s insolvency of individual thrifts and the thrift deposit insurer created severe incentive problems lacking cash to close insolvent thrifts regulators induced nearly 10 billion of private capital to flow into the industry through mutual to stock conversions we test a theory of how regulators encouraged capitalimpaired mutual thrifts to convert by permitting them to pay dividends rather than rebuild capital we estimate the costs of this policy and interpret the 1991 federal deposit insurance corporation improvement act as requiring regulators to impose restraints on depository institutions parallel to debt covenants that prevent capital distributions by nonfinancial firms experiencing distress
