an analysis of default risk in mobile home credit abstract there are approximately us 22 billion in outstanding receivables and an active secondary market for mobile home credit in the united states this important segment of the financing industry shares some attributes with traditional home mortgage financing and other attributes with consumer credit in this paper we draw on the mortgage literature to postulate the determinants of default risk for mobile home loans using multivariate logit models we investigate the relevance of payment history loan terms borrower characteristics economic conditions and legal constraints in analyzing loan defaults and delinquencies payment history emerges as the overwhelming factor in predicting the likelihood of default

rent seeking bureaucracies and oversight in a simple growth model abstract following recent cross country empirical work research on public policy and growth has come to examine the impact of inefficient or corrupt bureaucracies most of this work has emphasized the interactions of bureaucracies with private markets by contrast this paper focuses on the relationship between rent seeking bureaucracies and their political authority we show that when oversight is relatively costly as in many developing economies the political authority exercises little monitoring of its agencies which reduces the effectiveness of productive government spending moreover when the technology used to provide public services is poor bureaus better succeed in requesting overly large budgets before triggering any monitoring both of these characteristics contribute to reducing the growth rate of already poor economies

estimation of financial agent based models with simulated maximum likelihood abstract this paper proposes a general computational framework for empirical estimation of financial agent based models for which criterion functions have unknown analytical form for this purpose we adapt a recently developed nonparametric simulated maximum likelihood estimation based on kernel methods in combination with the model developed by brock and hommes 1998 which is one of the most widely analysed heterogeneous agent models in the literature we extensively test the properties and behaviour of the estimation framework as well as its ability to recover parameters consistently and efficiently using simulations key empirical findings indicate the statistical insignificance of the switching coefficient but markedly significant belief parameters that define heterogeneous trading regimes with a predominance of trend following over contrarian strategies in addition we document a slight proportional dominance of fundamentalists over trend following chartists in major world markets

a theory of corporate capital structure and investment this article uses a general equilibrium framework to explore the origins and limitations of financial intermediaries in the model investors have a generic lending technology that they can improve at a cost those who upgrade become intermediaries to exploit their advantage however conflicts with depositors will limit the banks market presence and they will only lend to moderately endowed firms while bondholders will finance cash rich corporations the article also analyzes the extent to which investors adopt the superior lending technique the nature of bank competition and how corporate and bank conditions affect interest rates and investment copyright 2004 oxford university press

the availability doctrine abstract this paper develops a general equilibrium model in which monetary disturbances have effects reminiscent of roosa s classic description of the availability doctrine the model is a marriage of the modern credit rationing literature and the recent sluggish cash flow models of monetary transmission both elements are crucial the credit rationing aspect leads to a focus upon the quantity or availability of credit however the rationing model in and of itself is a real model and there is no reason for fluctuations in the nominal quantity of fiat money to have any effect on the availability of real credit this is where the sluggish cash flow assumption enters into the analysis under this assumption changes in the nominal supply of fiat money do affect the real supply of credit because a subset of the economy absorbs a disproportionate share of the monetary injection

is relationship lending special evidence from credit file data in germany the german financial market is often characterized as a bank based system with strong bank customer relationships the corresponding notion of a housebank is closely related to the theoretical idea of relationship lending it is the objective of this paper to provide a direct comparison between housebanks and normal banks as to their credit policy therefore we analyze a new data set representing a random sample of borrowers drawn from the credit portfolios of five leading german banks over a period of five years we use credit file data rather than industry survey data and thus focus the analysis on information that is directly related to actual credit decisions in particular we use bank internal borrower rating data to evaluate borrower quality and the bank s own assessment of its housebank status to control for information intensive relationships the major results of our study support the view that housebanks are able to establish a distinct behavioral pattern consistent with the idea of long term commitment we find that housebanks do provide liquidity insurance in situations of unexpected deterioration of borrower ratings with respect to loan pricing we find no evidence for intra or intertemporal price differentiation related to housebanking

credit rationing concessionary lending and debt maturity abstract a firm raises capital for a two period investment while creditors observe the project status midstream unobservable managerial perks may consume capital each period when the firm is unfortunate early on short term financing results in either concessionary lending or costly liquidation rolling over short term debt may be problematic because the high risk premium creditors demand when asset value is low relative to debt impares managerial motivation precisely when the incentive to defer perk consumption is weakest long term financing may reduce total agency costs be enabling lenders to charge higher initial premia in effect shifting loan repayments to states in which incentive constraints are non binding

the nature of credit market failure abstract hidden knowledge gives rise to over lending if as evidence suggests the returns distributions preferred by borrowers are also favoured by lenders even the stiglitz weiss model yields over lending when entrepreneurs are sufficiently risk averse

car ownership employment and earnings abstract we assess whether the positive relationship between car ownership and employment outcomes reflects a causal effect of auto ownership we match state level data on car insurance premiums and gas taxes to a microdata sample containing information on car ownership and employment outcomes in ols regressions that control for observable covariates we find large differences in employment rates weekly hours worked and hourly earnings between those with and without cars instrumenting for car ownership with insurance and gas taxes yields estimates of the employment and hours effects that are quite close to the ols estimates concerning wages instrumenting eliminates the positive impact of auto ownership

intraday technical analysis of individual stocks on the tokyo stock exchange abstract this paper conducts an intraday technical analysis of individual stocks listed on the nikkei 225 in addition to the price based technical rules popularly examined in the literature we uniquely propose and statistically investigate technical rules that utilize information regarding 1 the order flow imbalance and 2 the order book imbalance technical analysis using the imbalance based trading rules is motivated by the evidence presented first in this paper that short term returns can be predicted from the information regarding the order flow and order book imbalances for more than half of nikkei 225 listed stocks however we demonstrate that no strategies including limit order trading where trading signals are derived from the order book imbalance beat the buy and hold strategy within our sample the results imply that past prices and demand supply imbalances do not contribute to profiting in intraday trading and that non execution and picking off risks are too large for limit order trading to be profitable in our sample

financial crises and recapitalizations we develop a dynamic stochastic general equilibrium model with financial frictions on both financial intermediaries and goods producing firms since financial intermediaries are highly leveraged we show that the welfare gains from their recapitalization in response to large but rare net worth losses are as large as those from eliminating typical business cycle fluctuations we also find that these gains are increasing in the size of the net worth loss are larger when recapitalization funds are raised from the household rather than the real sector and can be larger when lower idiosyncratic risk leads to higher leverage

the use of technical analysis in the foreign exchange market abstract technica or chartist analysis of financial markets involves providing forecasts or trading advice on the basis of largely visual inspection of past prices without regard to any underlying economic or fundamental analysis this paper reports the results of a questionnaire survey conducted on behalf of the bank of england among chief foreign exchange dealers based in london in november 1988 amongst other findings it is revealed that at least 90 per cent of respondents place some weight on this form of non fundamental analysis when forming views at one or more time horizons there is also a skew towards reliance on technical as opposed to fundamentalist analysis at shorter horizons which becomes steadily reversed as the length of horizon considered is increased a very high proportion of chief dealers view technical and fundamental analysis as complementary forms of analysis and a substantial proportion suggest that technical advice may be self fulfilling jel f31

elasticities of transport fuels at times of economic crisis an empirical analysis for spain abstract this paper provides an updated calculation of the price and income responsiveness of spanish consumers of transport fuels with an explicit exploration of the effects of the recent economic crisis we examine separate gasoline and diesel demand models using a set of estimators on a panel of 16 spanish regions over the period 1999 2015 the paper confirms the persistence of low own price elasticities both for diesel and gasoline in the short and long runs it also shows that the crisis of 2008 2013 slightly increased the price elasticity of demand for transport fuels with a higher effect on diesel than on gasoline by contrary the crisis slightly reduced the income elasticity of transport fuel demand given the intensity and length of the economic recession in spain the results of this paper may be useful to anticipate the effects of domestic public policies that impact transport fuel prices as well as to advance some of the potential consequences of crises elsewhere

signaling in credit markets in this paper we show that under a variety of alternative assumptions about the private information of loan applicants a competitive market for loans is characterized by screening banks separate out loan risks by offering higher loans at higher interest rates depending on the nature of the informational asymmetry it may be that applicants with less risky projects select larger rather than smaller loans comparative statics implications are also examined in particular we explore the effects of an increase in banks cost of funds on average loan quality

explaining dispersion in foreign exchange expectations a heterogeneous agent approach this paper combines survey forecasts with a heterogeneous agent model to examine the dispersion of expectations of participants in the foreign exchange market we find distinct variations in the level of dispersion and document that dispersion arises because of the combined effect of market participants holding private information and attaching different weights to fundamental technical and carry trade analyses we estimate a heterogeneous agent model on the survey forecasts and show that the weight attached to the three forecast rules is adjusted over time in response to the relative importance of the rules in the actual foreign exchange market the weights are related to market circumstances the switching model is finally shown to outperform the random walk model in an out of sample forecast exercise

the adaptive markets hypothesis evidence from the foreign exchange market we analyze the intertemporal stability of excess returns to technical trading rules in the foreign exchange market by conducting true out of sample tests on previously studied rules the excess returns of the 1970s and 1980s were genuine and not just the result of data mining but these profit opportunities had disappeared by the early 1990s for filter and moving average rules returns to less studied rules also have declined but have probably not completely disappeared high volatility prevents precise estimation of mean returns these regularities are consistent with the adaptive markets hypothesis lo 2004 but not with the efficient markets hypothesis

the benefits of lending relationships evidence from small business data this paper empirically examines how ties between a firm and its creditors affect the availability and cost of funds to the firm we analyze data collected in a survey of small firms by the small business administration the primary benefit of building close ties with an institutional creditor is that the availability of financing increases we find smaller effects on the price of credit attempts to widen the circle of relationships by borrowing from multiple lenders increases the price and reduces the availability of credit in sum relationships are valuable and appear to operate more through quantities rather than prices

some evidence on the empirical significance of credit rationing this paper examines the credit rationing debate using detailed contract information on over one million commercial bank loans from 1977 to 1988 while commercial loan rates are sticky consistent with rationing this stickiness varies with loan contract terms in ways that are not predicted by equilibrium credit rationing theory in addition the proportion of new loans issued under commitment does not increase significantly when credit markets are tight despite the fact that borrowers without commitments can be rationed whereas commitment borrowers are contractually insulated from rationing overall the data suggest that equilibrium rationing is not a significant macroeconomic phenomenon

the effectiveness of keynes tobin transaction taxes when heterogeneous agents can trade in different markets a behavioral finance approach abstract we develop a model in which boundedly rational agents apply technical and fundamental analysis to identify trading signals in two different speculative markets whether an agent trades and if so in which market with which strategy depends on profit considerations as it turns out an ongoing evolutionary competition between the trading strategies causes complex price dynamics which closely resembles the behavior of actual speculative prices moreover we find that if the agents have to pay a transaction tax in one market price variability decreases in this market but increases in the other market however the imposition of a uniform tax on all transactions stabilizes both markets our results suggest that if regulators of a market introduce a transaction tax other markets are likely to follow

the microfinance promise in the past decade microfinance programs have demonstrated that it is possible to lend to low income households while maintaining high repayment rates even without requiring collateral the programs promise a revolution in approaches to alleviating poverty and spreading financial services and millions of poor households are served globally a growing body of economic theory demonstrates how new contractual forms offer a key to microfinance success particularly the use of group lending contracts with joint liability for the most part however high repayment rates have not translated into profits and studies of impacts on poverty yield a mixed picture in describing emerging tensions the paper highlights the diversity of innovative mechanisms beyond group lending contracts the measurement of financial sustainability the estimation of economic and social impacts the costs and benefits of subsidization and the potential to reduce poverty through savings programs rather than just credit the promise of microfinance has pushed far ahead of the evidence and an agenda is put forward for addressing critical empirical gaps and sharpening the terms of policy discussion

modelling the transport sector fuel demand for developng economies abstract this paper concentrates on the transport sector of six developing countries with similar common denominators namely turkey thailand pakistan morocco tunisia and malaysia by using standard econometric techniques we analyse the evolution of oil demand for road transport in these countries in relation to independent variables such as income population price of gasoline and diesel etc unlike the treatment in the present literature on the subject gasoline and diesel consumption are estimated separately due to the high share of diesel in the total transport sector consumption on the basis of the estimation over the period 1970 1990 on a country by country basis we forecast the demand for these six countries until 2010 the results of this study indicate that the transport sector will be the driving force for energy and oil demand as part of economic growth in these developing countries its share in the future energy market structure is expected to grow consequently the pricing policies of oil products in this sector have a crucial role for shaping rational economic and energy strategies within the framework of rising environmental concern

limited liability and incentive contracting with ex ante action choices abstract this article examines a principal agent model of financial contracting in which a risk neutral entrepreneur agent makes an unobservable ex ante effort choice while employing the investment funds of a risk neutral investor principal the key innovation is that the investment contract is subject to statutory liability limits given these liability limits two settings are considered one in which the investor payoff function is also constrained to be monotonically nondecreasing in firm profit and another in which no such monotonic contract constraint is imposed in the former case a standard debt contract is shown to emerge and a first best effort choice is not achieved in the latter setting the optimum is characterized by a live or die payoff function and a first best effort level may or may not be realized

overcoming information asymmetries in low income lending lessons from the working wheels program without access to transportation the welfare to work transition is nearly impossible yet little is known about the effectiveness of programs designed to improve credit access since 1998 vermont s tanf funds have provided automobile loans through the working wheels program we use microlevel data from this program to explore how to cost effectively provide loans to clients who cannot obtain affordable loans elsewhere our results verify the importance of relationship lending particularly among those without documented credit histories in the presence of information asymmetries about credit history our results justify the increased trust placed in clients with whom the bank has a stronger relationship such clients ceteris paribus are less likely to default we conclude that in the current climate of welfare reform policymakers should consider programs that encourage welfare recipients to establish and maintain relationships with financial institutions in order to facilitate access to credit and minimize the risk of default

strategy switching in the japanese stock market abstract this paper investigates the expectation formation process of japanese stock market professionals by utilizing a monthly forecast survey dataset on the topix distributed by quick corporation we sort forecasters into buy side and sell side professionals we empirically demonstrate that the buy side and sell side professionals use either fundamental or trend following strategies throughout their expectation formation processes and that they switch between fundamental and trend following strategies over time we also discuss that strategy switching can be key in understanding the persistent deviation of the topix from the fundamentals

how good are standard debt contracts stochastic versus nonstochastic monitoring in a costly state verification environment the authors investigate ex ante efficient contracts in an environment in which implementation is costless in this environment standard debt contracts will typically not be optimal optimal contracts may involve defaults even in states in which the borrower is fully able to repay the authors then examine the welfare costs of arbitrarily restricting the set of feasible contracts to standard debt contracts when model parameters are calibrated to realistic values the welfare loss from exogenously imposing this restriction is extremely small thus if implementation costs are actually nontrivial as seems likely standard debt contracts will be very close to optimal copyright 1994 by university of chicago press

imperfect information and the theory of government intervention in farm credit markets this paper describes some possible economic motivations for government intervention in farm credit markets these motivations are made possible by explicit departures from the perfect information and complete market assumptions that underlie both the neoclassical competitive paradigm and the fundamental theorems of welfare economics to be more precise the analysis focuses on three types of asymmetric information between farmers and prospective outside investors both of whom are assumed to be risk neutral arguably the three informational asymmetries examined here represent natural departures from perfect markets in that unlike the unencumbered neoclassical model each elicits farmers optimal use of debt contracts rather than equity instruments or other contractual forms to raise investment capital despite their consistency with observed contractual choices all three of the models analyzed below yield free market equilibria that diverge from first best perfect information outcomes given the inefficiency of these market equilibria the key question raised and discussed here is can government improve upon the derived competitive outcomes and if so how despite the enormity of the credit rationing literature only a few extant studies address this question in models that are consistent with debt contracts among them are demeza and webb 1987 1988 1989 and innes 1988 which focus on the third type of informational asymmetry considered below the other two information structures posited in this paper have been studied in several analyses of credit markets but with attention focused on positive attributes of the unfettered competitive equilibrium rather than on prospective implications for welfare enhancing government intervention in what follows th s literature is surveyed and for the first two information structures some new policy results a e presented a critical discussion of the paper s limitations concludes the article

monetary policy bank leverage and financial stability abstract this paper shows that with limited liability banks lever up excessively to finance new loans lower monetary policy rates can worsen or reduce these incentives depending on the size of the shock when equity financing is ruled out when this constrained is relaxed but the bank faces costly dividend adjustment lower monetary policy rates always worsen risk taking incentives and the effect is persistent the reason is that costly dividend adjustment lowers the opportunity cost of lending in this model capital requirements are closer to the source of the distortion and thus work better than loan to value caps in reducing excessive risk taking

moral hazard under commercial and universal banking many claims have been made about the potential benefits and the potential costs of adopting a system of universal banlcing in the united states we evaluate these claims using a model where there is a moral hazard problem between banks and borrowers a moral hazard problem between banks and a deposit insurer and a costly state verification problem under conditions we describe allowing banks to take equity positions in firms strengthens their ability to extract surplus and exacerbates problems of moral hazard the incentives of universal banks to take equity positions will often be strongest when these problems are most severe for many decades commercial banks in the united states have been prohibited from making equity investments in the firms they serve rather they are restricted to providing them with loans in the form essentially of debt contracts this longstanding regulatory restriction1 results in distinctly different roles for bank lenders and equity investors and has had important implications for the entire financial sector the american system of commercial banking presents a sharp contrast with the banking systems of some other countries most notably germany in which banks are permitted to take equity positions under such universal banking arrangements banks can make equity investments as well as loans vote their equity shares and even hold seats on the boards of directors of nonfinancial firms in general they can be actively involved in all aspects of firm decision malqing in germany the control rights the authors have benefitted from the helpful comments of doug diamond joe haubrich ross levine stan longhofer joao santos and an anonymous referee the views expressed herein are those of the authors and not necessarily those of the federal reserve bank of minneapolis or the federal reserve system 1 the key legislation which constrains u s banks equity investments is the glass steagall act of 1933 however a number of other laws also pertain to this issue particularly the bank holding company act of 1956 and its 1970 amendments incidentally there are some important exceptions to the equity investment prohibition in default situations banks are perrnitted to restructure loans into equity positions with the requirement of divestiture after a few years see james 1993 also bank holding companies are permitted to form separately capitalized venture capital subsidiaries for the expressed purpose of investing in start up enterprises john h boyd is a professor of finance in the carlson school of management at the university of minnesota and an adjunct consultant with the federal reserve bank of minneapolis chun chang is an associate professor of finance in the carlson school of management at the university of minnesota bruce d smith is a professor of economics at the university of texas ataustin

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

relationships and rationing in consumer loans we empirically examine how relationships between individual households and their creditors affect the probability of being credit rationed using a data set where the credit rationing of individual households is observed directly we show that relationship duration and the number of activities between a family and a potential lender significantly lower the probability of being credit rationed additionally we examine the relative role of relationships in determining the interest rates of two consumer loans a mortgage loan and a special purposes loan and show that mortgage loan rates are driven less by relationship factors than the special purposes loan rates copyright 1999 by university of chicago press

a re examination of stationarity of energy consumption evidence from new unit root tests abstract in this paper we re examine the stochastic behaviour of per capita total primary energy consumption across 178 countries around the world for this purpose in addition to conventional unit root tests we apply newly developed tests that allow for nonlinear adjustments and structural breaks in the data generating process the results of the unit root tests show that allowing for structural breaks and nonlinearity result in more frequent rejection of the null hypothesis of unit root suggesting that most of the series under consideration follow a stationary process these findings imply that both energy economists and policy makers must be careful and take account of possible nonlinearities and structural breaks in their analyses of energy consumption in addition the results imply that government interventions into the energy markets in most countries have no effect in the long run although the short run effects of the interventions depend on the size and the direction of interventions

order aggressiveness pre trade transparency and long memory in an order driven market abstract recent empirical research has documented that the state of the limit order book influences stock investors strategies investors place more aggressive orders when the same side of the order book is thicker and less aggressive orders when it is thinner we conjecture and demonstrate that this behavior is related to long memories of trading volume volatility and order signs in stock markets we investigate our conjecture in two types of artificial stock markets a transparent market in which agents observe all limit orders on both sides of the book and order volumes at those prices before they trade and a less transparent market in which agents observe only the best five bid and ask quotes with the depth available at these limit prices the first market structure resembles certain actual stock exchanges in the level of pre trade transparency such as the australian stock exchange nyse openbook and the london stock exchange whereas the second market structure is consistent with stock exchanges such as euronext paris the toronto stock exchange the tokyo stock exchange and hong kong exchanges and clearing we demonstrate that our long memory results are robust with different levels of pre trade transparency implying that the strategy constructed by the state of the order book is key for explaining long memories in many actual stock exchanges

this is what happened to the oil price macroeconomy relationship abstract many of the quarterly oil price increases observed since 1985 are corrections to even bigger oil price decreases the previous quarter when one looks at the net increase in oil prices over the year recent data are consistent with the historical correlation between oil shocks and recessions

gasoline demand in the oecd an application of pooling and testing procedures abstract this study utilizes a pooled inter country data set finding the long run price elasticity falls in the range 0 55 to 0 9 depending on the choice of pooled estimators the estimators included the ols within and between country estimators plus five feasible gls estimators even allowing for a ten year distributed lag on price to reflect changes in auto efficiency characteristics the within country estimator yields appreciably more inelastic estimates than did the o s estimator which was heavily influenced by the between or inter country variation this difference raises intriguing questions for future research

the macroeconomic implications of financial deregulation abstract this paper explores the possible macroeconomic consequences of financial deregulation in an institutional environment where deregulation raises risks in banking the central bank is supposed to maximize an objective function in which the probability of bank failure is an argument it is then shown that the usual tradeoffs between policy objectives imply that financial deregulation will lead to more interest rate smoothing than would otherwise take place and further that because of restricted entry into banking deregulation will call for some inflation the transition toward deregulation raises special problems which are likely to require a more gradual approach toward the stationary equilibrium

monetary policy in a dollarized economy where balance sheets matter abstract does the dollarization of liabilites and the resulting balance sheet vulnerability prevent monetary policy from serving its conventional countercyclical role we study this question in a model of a small open economy in which domestic firms face an imperfect capital market with risk premia depending on net worth as in bernanke and gertler am econ rev 79 1989 14 in spite of the financial fragility channels present in the model the conventional wisdom still holds under a floating exchange rate countercyclical monetary policy does help cushion the impact of foreign real shocks

measuring global gasoline and diesel price and income elasticities abstract price and income elasticities of transport fuel demand have numerous applications they help forecast increases in fuel consumption as countries get richer they help develop appropriate tax policies to curtail consumption help determine how the transport fuel mix might evolve and show the price response to a fuel disruption given their usefulness it is understandable why hundreds of studies have focused on measuring such elasticities for gasoline and diesel fuel consumption in this paper i focus my attention on price and income elasticities in the existing studies to see what can be learned from them i summarize the elasticities from these historical studies i use statistical analysis to investigate whether income and price elasticities seem to be constant across countries with different incomes and prices although income and price elasticities for gasoline and diesel fuel are not found to be the same at high and low incomes and at high and low prices patterns emerge that allow me to develop suggested price and income elasticities for gasoline and diesel demand for over one hundred countries i adjust these elasticities for recent fuel mix policies and suggest an agenda of future research topics

income elasticity of gasoline demand a meta analysis abstract in this paper we quantitatively synthesize empirical estimates of the income elasticity of gasoline demand reported in previous studies the studies cover many countries and report a mean elasticity of 0 28 for the short run and 0 66 for the long run we show however that these mean estimates are biased upwards because of publication bias the tendency to suppress negative and insignificant estimates of the elasticity we employ mixed effects multilevel meta regression to filter out publication bias from the literature our results suggest that the income elasticity of gasoline demand is on average much smaller than reported in previous surveys the mean corrected for publication bias is 0 1 for the short run and 0 23 for the long run

motor fuel prices in turkey the world s most expensive motor fuel gasoline diesel and lpg is sold most likely in the republic of turkey this paper investigates the key issues related to the motor fuel prices in turkey first of all the paper analyses the main reason behind high prices namely motor fuel taxes in turkey then it estimates the elasticity of motor fuel demand in turkey using an econometric analysis the findings indicate that motor fuel demand in turkey is quite inelastic and therefore not responsive to price increases caused by an increase in either pre tax prices or taxes therefore fuel market in turkey is open to opportunistic behaviour by firms through excessive profits and the government through excessive taxes besides the paper focuses on the impact of high motor fuel prices on road transport associated activities including the pattern of passenger transportation motorization rate fuel use total kilometers travelled and co2 emissions from road transportation the impact of motor fuel prices on income distribution in turkey and turkish public opinion about high motor fuel prices are also among the subjects investigated in the course of the study

methodical madness technical analysis and the irrationality of exchange rate forecasts substantial empirical research documents that exchange rate forecasts are not formed rationally this paper identifies a common technical trading signal the head and shoulders pattern as a potential source of departures from rationality in exchange rate forecasts forecasts based on this pattern are evaluated for daily dollar exchange rates over 1973 to 1994 using two criteria for rationality profitability and efficiency resulting profits replicable in real time are tested for statistical significance using a bootstrap technique we find that the rule is profitable but not efficient since it is dominated by simpler trading rules

a cointegration analysis of gasoline demand in the united states time series estimation of gasoline demand elasticities often does not take into account the possibility of nonstationarity in the underlying data which may render the parameter estimates spurious studies have shown that the time trending variables used to explain gasoline demand could be difference stationary and therefore may require cointegration analysis to assess the relationship among the trending variables in this work we use the cointegration technique to derive long run and short run demand elasticities of noncommercial gasoline consumption using time series data for the usa from 1949 to 2004 we also attempt to incorporate the presence of a structural break in the data generation process of the time trending variables our results show that the consumption of gasoline and lifetime income have a long term stable relationship after the second oil shock of 1978 prior to the first oil shock of 1973 no such long run relationship could be established through cointegration

the use of flow analysis in foreign exchange exploratory evidence abstract this paper provides questionnaire evidence on the role of flow analysis for professional traders and fund managers this evidence suggests that besides fundamental information and technical analysis the analysis of flows provides an independent third type of information for professionals the view that flows can be used to learn about fundamentals is not consistent with the data instead evidence indicates that flows more likely provide insight into semi fundamental private information

exchange rate economics 1986 in the past fifteen years key exchange rates have moved in larger and more persistent ways than advocates of flexible rates in the late 1960s would have left anyone free to imagine certainly there was no expectation of constancy for nominal exchange rates but real exchange rate movements of 30 or forty percent were definitely not suggested as a realistic possibility moreover where these large movements did occur they did not obviously appear to be connected with fundamentals and hence seemed difficult to explain in terms of the exchange rate theories at hand the persistence of rate movements was as surprising as the rapid unwinding of apparent misalignments when they did ultimately occur the past fifteen years provide a natural dividing line between the keynesian and monetary approaches of the 1960s and the more recent analysis that takes into account exchange rate expectations and portfolio issues which took off in the early 1970s as well as the brand new approaches that concentrate on partial equilibrium microeconomics to review these ideas the paper starts with a brief look at the u s experience with flexible exchange rates from there it proceeds to the mundell fleming model as a comprehensive framework of analysis the following sections deal with persistent effects of policy disturbances links between exchange rates and prices the political economy of exchange rate movements and the question of policies toward excess capital mobility this abstract was borrowed from another version of this item

bank lending policy credit scoring and the survival of loans to evaluate loan applicants banks increasingly use credit scoring models the objective of such models typically is to minimize default rates or the number of incorrectly classified loans thereby they fail to take into account that loans are multiperiod contracts for which reason it is important for banks not only to know if but also when a loan will default in this paper a bivariate tobit model with a variable censoring threshold and sample selection effects is estimated for 1 the decision to provide a loan or not and 2 the survival time of granted loans the model proves to be an effective tool to separate applicants with short and with long survival times the bank s loan provision process is shown to be inefficient loans are granted in a way that conflicts with both default risk minimization and survival time maximization there is thus no trade off between higher default risk and higher return in the lending policy

credit rationing and the demand for owner occupied housing abstract this study applies cross sectional data to test whether default risk induced credit constraints affect the demand for owner occupied housing credit constrained households are argued to exhibit different elasticities of demand for housing than less constrained households housing demand elasticities are then estimated separately for households obtaining va insured and non va loans the government guarantee on va loans insures lenders against default enabling lenders to apply easier nonprice terms of credit results indicate that observed demand elasticities differ significantly across va and conventional mortgage holders that marginal changes in credit constraints affect housing demand and that fha financing mitigates the effect of mortgage constraints

expectation formation in the foreign exchange market a time varying heterogeneity approach using survey data using consensus economics survey data on jpy usd and gbp usd exchange rate expectations for the 3 and 12 month horizons over the period november 1989 december 2012 we first show that expectations fail the conventional tests of unbiasedness and do not exhibit a learning process towards rationality our approach is consistent with the economically rational expectations theory feige and pearce 1976 which states that information costs and agents aversion to misestimating future exchange rates determine the optimal amounts of information on which they base their expectations the time variability of the cost aversion ratios justifies at the aggregate level a representation of expectations as a linear combination of the traditional extrapolative adaptive and regressive processes augmented by a forward market component whose parameters are allowed to change over time this mixed expectation model with unstable heterogeneity is validated by our kalman filter estimation results for the two currencies and

short run long run and cross elasticities of gasoline demand in brazil gasoline is one of the most important of the oil derived products its importance is closely related to its participation in the value of imports of many countries and in a number of cases it is one of the determinants of their balance of payment deficit fiscal deficit and economic growth as opposed to most nations brazil has had a gasoline substitute since 1985 alcohol many studies have tried to estimate the income and price elasticities of the demand for gasoline in several countries this paper extends previous studies by estimating the cross price elasticity between gasoline and alcohol our findings indicate that alcohol is an imperfect substitute for gasoline even in the long run as a consequence the need for a new fuel substitution must be initiated long before petroleum reserves vanish

the economic value of fundamental and technical information in emerging currency markets abstract we measure the economic value of information derived from macroeconomic variables and from technical trading rules for emerging markets currency investments our analysis is based on a sample of 21 emerging markets with a floating exchange rate regime over the period 1997 2007 and explicitly accounts for trading restrictions on foreign capital movements by using non deliverable forward data we document that both types of information can be exploited to implement profitable trading strategies in line with evidence from surveys of foreign exchange professionals concerning the use of fundamental and technical analysis we find that combining the two types of information improves the risk adjusted performance of the investment strategies

analysing gasoline demand elasticities a survey this paper is a survey of studies on gasoline demand although there are very many dxerent studies in this eld which sometimes appear to arrive at contradictory results we find that with proper stratification of studies by model and data type much of the contict turns to consensus in this survey we classtfy studies by data type and by ten d erent categories of model and with the exception of estimates on seasonal data which tend to be unstable and of certain inappropriate model formulations we find a fair degree of agreement concerning average short run and even long run income and price elasticities

heterogeneous expectations exchange rate dynamics and predictability abstract this paper proposes a simple chartist fundamentalist model in which we allow for nonlinear time variation in chartists extrapolation rate estimation of the model using monthly data for the major currencies vis a vis the us dollar shows that the model is significant in sample and that it has out of sample predictive power for some of the currencies we investigate the power of tests of the random walk model to detect predictability against the alternative of the proposed model we find that the evidence of short term unpredictability and the long term predictability are consistent with our model

financial structure and aggregate economic activity an overview this paper surveys literature that explores the possible links between the financial system and aggregate economic behavior the survey is in two parts the first reviews the traditional work and the second discusses new research copyright 1988 by ohio state university press

should courts enforce credit contracts strictly the intimate linkages between law and nance are currently the centre of wide rangingempirical investigations this article presents a simple banking model with informationasymmetries concerning borrowers entrepreneurial talent it is shown that improvements inthe enforcement of contract by courts reduce agency problems but can also reduce the bank sincentive to screen borrowers adequately thus worsening credit allocation a stricterenforcement of credit contracts therefore may be socially harmful even if costlessly achieved improvements in accounting standards however always make bank screening of borrowers lesscostly and improve credit allocation and social welfare

loan performance and race r carter hill recent studies find evidence of racial discrimination in mortgage markets although these studies explore loan approval rates for whites versus minorities they do not specifically consider loan performance either in the form of default rates or loan administration costs this study considers discrimination in the used car credit market where the collateral is not subject to location externalities collateral value and quality do not vary as much as in real estate and the loan terms are shorter we find administration costs and default rates are higher for minorities than for whites controlling for age income home ownership wealth occupation loan terms and geographic location jel k2 i introduction credit discrimination occurs whenever minorities are denied credit on the basis of race or are offered loans at terms different than the terms offered similarly situated whites 1 economists identify two types of discrimination preference taste based discrimination and information statistical based discrimination 2 the legal definition of discrimination makes no such distinction in their statistical studies munnell brown mceneaney and tootell 1996 carr and megbolugbe 1994 and gabriel and rosenthal 1991 find evidence of discrimination whereas most economic theorists such as becker 1993 and commentators such as brimelow 1993 and brimelow and spencer 1993 argue competition will greatly reduce if not eliminate discrimination in section iii we demonstrate why under regulation statistical discrimination may increase with increasing competition this anomalous result occurs because the legal definition does not distinguish between the two types of discrimination some economists implicitly assume credit markets are unregulated when considering the effect of competition on discrimination antidiscrimination regulation changes the effect of competition in unregulated markets taste based discrimination is unprofitable and increasing competition will reduce this form of discrimination if the industry s employees or white borrowers have a taste for discrimination competition will not necessarily eliminate taste based discrimination when regulation is binding and the economic foundation for statistical discrimination exists discrimination is profitable and increasing competition may increase discrimination the effect of regulation and competition on discrimination depends critically on the information basis for discrimination the relationship between loan performance and race therefore the appropriate empirical question is does a statistical basis for discrimination exist this question cannot be answered by loan approval studies rather it must be addressed by evaluating how loans perform after they are approved further the appropriate public policy issue is should society regulate statistical discrimination this article is an empirical inquiry into the relationship between race and loan performance we measure loan performance by estimating the same marginal default rates that lenders use to score credit applications and by the variables that have the most impact on loan administration costs we find that race matters regrettably in the fashion suggested by stereotypes in general minorities have higher default rates and contribute to higher administration costs in other words the foundation for statistical discrimination appears to exist section ii contains a review of the extant literature a theoretical model of credit scoring with both taste and statistical discrimination is contained in section iii the data are discussed in section iv and the empirical models are presented in section v ii literature as in arrow 1973 and becker 1957 an individual is said to have a preference or taste for discrimination if he is willing to pay a price or forgo income in order to practice discrimination

deposit insurance a reconsideration abstract this paper undertakes a simple general equilibrium analysis of the consequences of deposit insurance programs the way in which they are priced and the way in which they fund revenue shortfalls in our economy the central issue in analyzing deposit insurance is how the government will make up any fdic losses deposit insurance premia matter only in so far as they affect the level of implied fdic revenue shortfalls moreover local variations in the magnitude of fdic losses will generically be irrelevant for the determination of any equilibrium quantities that affect agent welfare however large enough changes in these losses can matter there is no presumption that keeping these shortfalls low is a good idea finally we show that multiple pareto ranked equilibria can be observed the potential for multiplicity of equilibria may depend on components of fdic policy our analysis provides counterexamples to the following propositions 1 actuarially fair pricing of deposit insurance is always desirable 2 implicit fdic subsidization of banks through deposit insurance is always undesirable 3 large fdic losses are necessarily symptomatic of a poorly designed deposit insurance system 4 risk based deposit insurance premia can easily be used to reduce moral hazard problems associated with deposit insurance provision

the asymmetric effects of oil price and monetary policy shocks a nonlinear var approach in this paper we investigate the asymmetric effects of oil price shocks and monetary policy on macroeconomic activity using monthly data for the united states over the period from 1983 1 to 2008 12 in doing so we use a logistic smooth transition vector autoregression var as detailed in terasvirta and anderson 1992 and weise 1999 and make a distinction between two oil price volatility regimes high and low using the realized oil price volatility as a switching variable we isolate the effects of oil price and monetary policy shocks and their asymmetry on output growth and following koop et al 1996 and weise 1999 we employ simulation methods to calculate generalized impulse response functions girfs to trace the effects of independent shocks on the conditional means of the variables our results suggest that in addition to the price of oil oil price volatility has an impact on macroeconomic activity and that monetary policy is not only reinforcing the effects of oil price shocks on output it is also contributing to the asymmetric response of output to oil price shocks

equilibrium subprime lending this paper develops an equilibrium model of a subprime mortgage market our goal is to offer a benchmark with which the recent subprime boom and bust can be compared the model is tractable and delivers plausible orders of magnitude for borrowing capacities as well as default and trading intensities we offer simple explanations for several phenomena in the subprime market such as the prevalence of teaser rates and the clustering of defaults in our model both nondiversifiable and diversifiable income risks reduce debt capacities thus debt capacities need not be higher when a larger fraction of income risk is diversifiable

the credit constrained consumer an empirical study of demand and supply in the loan market this article presents an empirical analysis of credit constrained households in which models of both demand and supply sides of the market for loans are simultaneously estimated we develop a discrete choice logit model of the consumers decision on whether or not to apply for credit combining this with a reduced form logistic model for the banks credit granting decision we then estimate the model with cross sectional data as a nonlinear ordered sequential logit our findings shed light on the criteria used by banks in assessing credit applications and reveal the strong dependence of preferences on demographic characteristics the results also suggest that agents face significant fixed costs in applying for loans the fact that we jointly estimate models of both supply and demand sides of the credit market enables us to examine whether particular groups in the population are more frequently credit rationed because they tend to demand more loans or because they are viewed as bad credit risks by lenders

the use of fundamental and technical analyses by foreign exchange dealers hong kong evidence abstract this article reports the results of a questionnaire survey conducted in february 1995 on the use by foreign exchange dealers in hong kong of fundamental and technical analyses to form their forecasts of exchange rate movements our findings reveal that 85 of respondents rely on both fundamental and technical analyses for predicting future rate movements at different time horizons at shorter horizons there exists a skew towards reliance on technical analysis as opposed to fundamental analysis but the skew becomes steadily reversed as the length of horizon considered is extended technical analysis is considered slightly more useful in forecasting trends than fundamental analysis but significantly more useful in predicting turning points interest rate related news is found to be a relatively important fundamental factor in exchange rate forecasting while moving average and or other trend following systems are the most useful technical technique

have trading rule profits in the currency markets declined over time abstract previous studies have reported mixed results regarding the success of technical trading rules in currency markets abnormal returns were observed in many studies using data up to the mid 1980s while more recent studies generally report less success for technical trading rules this paper tests whether moving average trading rule profits have declined over the period from 1971 to 2000 if so previous profits may represent a temporary inefficiency that has since been eliminated in the currency markets the hypothesis is tested using 18 exchange rate series over a longer time period than in previous studies rules are optimized for successive 5 year in sample periods from 1971 to 1995 and tested over subsequent 5 year out of sample periods results show that risk adjusted trading rule profits have declined over time from an average of over 3 in the late 1970s and early 1980s to about zero in the 1990s thus market inefficiencies reported in previous studies may have been only temporary inefficiencies

symmetrical information and credit rationing graphical demonstrations as this article shows the pro debtor u s bankruptcy code alone can cause credit rationing even without asymmetrical information in the market because the code entails substantial costs to lenders if borrowers file for bankruptcy in the absence of bankruptcy cost lenders are always justified in raising interest rates and clearing markets if the bankruptcy cost is nontrivial however lenders profits are concave in the relevant range of interest rates thus lenders cannot always clear the market by using higher rates the study reported here also found that the use of collateral in debt contracts can reduce rationing but that even 100 percent collateral does not eliminate all rationing possibilities a positive relationship was found between credit risk and the amount of pledged collateral which is not necessarily true with models based on asymmetrical information

market efficiency of brazilian exchange rate evidence from variance ratio statistics and technical trading rules abstract this study utilizes the variance ratio test to examine the behavior of brazilian exchange rate we show that adjustments for multiple tests and a bootstrap methodology must be employed in order to avoid size distortions we propose a block bootstrap scheme and show that it has much nicer properties than the traditional chow denning chow k v denning k c 1993 a simple multiple variance ratio test journal of econometrics 58 3 385 401 multiple variance ratio tests overall the method proposed in the paper provides evidence refuting the random walk behavior for the brazilian exchange rate for long investment horizon but consistent with the random walk hypothesis for short run horizon additionally we also test for the predictive power of variable moving average vma and trading range break trb technical rules and find evidence of forecasting ability for these rules nonetheless the excess return that can be obtained from such rules is not significant suggesting that such predictability is not economically significant

the foreign exchange market a random walk with a dragging anchor this paper explores some anomalies in the foreign exchange market it is hard to find evidence of either short term overshooting or of longer term reversion to an equilibrium the forward exchange rate contains virtually no information on future spot rates discussions with practitioners indicate that longer term speculation based on fundamentals is strictly limited and survey data and other evidence suggest that expectations and speculation are based on a variety of models the interplay between speculation based on fundamentals and on a random walk or chartist approach influences the outcome this endorses the prior model of j a frankel and k a froot copyright 1988 by the london school of economics and political science

capital requirements monetary policy and aggregate bank lending theory and empirical evidence capital requirements linked solely to credit risk are shown to increase equilibrium credit rationing and lower aggregate lending the model predicts that the bank s decision to lend will cause an abnormal runup in the borrower s stock price and that this reaction will be greater the more capital constrained the bank i provide empirical support for this prediction the model explains the recent inability of the federal reserve to stimulate bank lending by increasing the money supply i show that increasing the money supply can either raise or lower lending when capital requirements are linked only to credit risk the motivation of this article is first to examine the impact of risk based capital requirements namely those that link mandatory capital to asset ratios for banks to their loans on aggregate bank lending these requirements called the basle capital rules or bis guidelines went into effect in march 1989 for banks in the leading industrialized nations these rules initially required banks to maintain capital equal to 7 25 percent of business and most consumer loans with the requirement increasing to 8 percent by the end of 1992 secondly i wish to understand the link between monetary policy and aggregate bank credit in the presence of risk based capital requirements my curiosity is sparked in part by two recent phenomena one is the experience of the u s economy which displayed sluggish growth during 1989 93 despite a monetary policy that attempted to spur bank lending and economic activity and the other is the striking decline in loans relative to security holdings mostly government bonds in the asset portfolios of u s

bank lending policy credit scoring and value at risk this paper builds on the credit scoring literature and proposes a method to calculate portfolio credit risk individual default risk estimates are used to compose a value at risk var measure of credit risk in general credit scoring models suffer from a sample selection bias the starting point is therefore to estimate an unbiased scoring model using the bivariate probit approach the paper uses a large data set with swedish consumer credit data that contains extensive financial and personal information on both rejected and approved applicants we study how marginal changes in a default risk based acceptance rule would shift the size of the banks loan portfolio its var exposure and average credit losses finally we compare the risk in the sample portfolio with that in an efficiently provided portfolio of equal size the results show that the size of a small consumer loan does not affect associated default risk implying that the bank provides loans in a way that is not consistent with default risk minimization var calculations indicate that an efficient selection by means of a default riskbased rule of loan applicants can reduce credit risk by up to 80 2002 elsevier science b v all rights reserved

the demand for transport fuels in turkey abstract in this paper we estimate the demand for transport fuels in turkey specifically using four different models namely a partial adjustment model a distributed lag model an autoregressive distributed lag model and an error correction model we estimate gasoline and diesel demand functions with quarterly data covering the period 2003 q1 2014 q3 we find a stable long run relationship only for diesel demand income and price our results imply that gasoline demand does not respond to income and price in the long run reflecting a shift from gasoline towards diesel induced by differential tax policies furthermore we find that transport fuel demand is price inelastic making tax on fuel a perfect tool for raising budget revenues in addition our results suggest that fuel demand responds to negative and positive price changes symmetrically

short and long run elasticities of gasoline demand in india an empirical analysis using cointegration techniques abstract in developing countries like india consumption of petroleum products has implications on its balance of payments economic growth and fiscal deficit gasoline is one of the prime petroleum products in this paper the relationship between gasoline demand national income and price of gasoline is empirically examined using cointegration and error correction techniques the time frame of the analysis is from 1972 1973 to 1993 1994 it has been found that gasoline demand is likely to increase significantly for a given increase in the gross domestic product the increase will be larger in the long run 2 682 than in the short run 1 178 gasoline demand is relatively inelastic to price changes both in the long and short terms the error correction model has shown that gasoline demand adjusts to their respective long run equilibrium at a relatively slow rate with about 28 of adjustment taking place in the first year

the beliefs of borrowers and lenders and investment decisions abstract this paper examines the role of beliefs in the determination of equilibrium in a standard model of credit markets and investment project choice with asymmetric information it is shown that with ex ante asymmetric information the beliefs of entrepreneurs are important for the equilibrium level of aggregate investment and with ex post asymmetric information the beliefs of creditors are important for the types of projects selected by entrepreneurs

price trends and patterns in technical analysis a theoretical and empirical examination while many technical trading rules are based upon patterns in asset prices we lack convincing explanations of how and why these patterns arise and why trading rules based on technical analysis are profitable this paper provides a model that explains the success of certain trading rules that are based on patterns in past prices we point to the importance of confirmation bias which has been shown to play a key role in other types of decision making traders who acquire information and trade on the basis of that information tend to bias their interpretation of subsequent information in the direction of their original view this produces autocorrelations and patterns of price movement that can predict future prices such as the head and shoulders and double top patterns the model also predicts that sequential price jumps for a particular stock will be positively autocorrelated we test this prediction and find that jumps exhibit statistically and economically significant positive autocorrelations

costly monitoring loan contracts and equilibrium credit rationing this paper develops a model with asymmetrically informed agents and costly monitoring of loan contracts where an equilibrium can exhibit credit rationing borrowers are identical ex ante but some receive loans and others do not in contrast to existing credit rationing theories rationing does not occur here due to inflexible prices adverse selection or moral hazard optimizing behaviour produces a standard debt contract in equilibrium the aggregate quantity of loans and equilibrium interest rates respond differently depending on whether there is rationing in equilibrium

exchange rate dynamics central bank interventions and chaos control methods abstract we use a simple chartist fundamentalist model developed by day and huang to explore recent chaos control algorithms as potential candidates for central bank intervention rules we find that methods such as delayed feedback control ogy and constant feedback have in principle the potential to reduce exchange rate variability and deviations from fundamentals even in the presence of large dynamic noise

learning with misspecification in an artificial currency market abstract agents evolve their forecast rules over time via a modified genetic algorithm in a simple artificial currency market these forecast rules can be nonlinearly misspecified when the misspecification is suppressed learning tends to be complete when it is not suppressed learning can generate persistent exchange rate dynamics

optimal contracts under costly state falsification we examine an exchange economy with two agents one risk neutral with a certain endowment and a second risk averse with a random endowment the realization of the endowment is public but can be falsified by the second agent at a cost for a broad class of falsification cost functions the optimal no falsification contract is noncontingent on a left hand interval and strictly increasing with a slope strictly less than one on a right hand interval under a mild further restriction optimal no falsification contracts are in addition piece wise linear optimal contracts may in general require falsifying the state but for a set of the highest endowment realizations there is no falsification we find simple conditions under which the optimal contract is a no falsification contract the model has applications that include financial insurance and employment contracts and tax policy

the growth effects of property rights the role of finance summary using a variety of statistical approaches we show that the relationship between property rights and growth is nonlinear stronger enforcement of property rights raises growth up to a point before growth begins to decline we provide a simple theoretical rationale for this conclusion using a model with informational asymmetries in the financial sector stronger property rights have two opposing effects on the one hand it increases capital formation and growth on the other hand it encourages bad borrowing practices thus there exists an optimal level of property rights which maximizes growth however as financial markets mature the negative effects associated with stronger property rights become weaker

temporal patterns in foreign exchange returns and options although the foreign exchange market is believed to be one of the most efficient financial markets in the world there is significant evidence that technical analysis is profitable in this market in this study we investigate the ability of information from the options market to supplement the commonly used information on past prices to predict temporal patterns in foreign exchange returns we find that information from the options market improves the performance of technical trading strategies strategies using information from at the money options were more consistently profitable than the most commonly used strategies based on only historical spot exchange rates past prices our results hold out of sample as well as in the late nineties a period when few sources of information have proven reliable consequently options appear to contain valuable information regarding future spot exchange rate movements
