balance of payment crises in emerging markets how early were the early warning signals although many papers have already proposed empirical models of currency crises the timing of such crises has received relatively little attention so far most papers use indeed a static specification and impose the same lag structure across all explanatory variables this by construction prevents from specifically timing the crisis signals sent by the leading indicators the objective here is to fill this gap by considering a set of dynamic discrete choice models the first contribution is to identify how early in advance each explanatory variable sends a warning signal some indicators are found to signal a crisis in the very short run while others signal a crisis at more distant horizons the second contribution is to show that state dependence matters albeit mostly in the short run the results have important implications for crisis prevention in terms of the timeliness and usefulness of the envisaged policy response

external liabilities and crises abstract we examine the determinants of external crises focusing on the role of foreign liabilities and their composition using a variety of statistical tools and comprehensive data spanning 1970 2011 we find that the ratio of net foreign liabilities to gdp is a significant crisis predictor this is primarily due to the net position in debt instruments the effect of net equity liabilities is weaker and net fdi liabilities seem if anything an offset factor we also find that i breaking down net external debt into its gross asset and liability counterparts does not add significant explanatory power to crisis prediction ii the current account is a powerful predictor iii foreign exchange reserves reduce the likelihood of crisis more than other foreign asset holdings and iv a parsimonious probit containing those and a handful of other variables has good predictive performance in and out of sample the latter result stems largely from our focus on external crises sensu stricto

on cross border bank credit and the u s financial crisis transmission to equity markets this paper examines the role played by cross border equity bond and bank credit flows versus international trade in the transmission of the u s financial crisis to equity markets worldwide we estimate vector autoregressive models with exogenous global factors using monthly data on 36 emerging and developed countries the results from an eclectic methodology that includes causality tests generalized impulse responses and forecast error variance decompositions indicate that the crisis is mostly transmitted through bank credit rather than portfolio flows and international trade the results are robust to altering the exogenous versus endogenous vectors of variables to measuring equity prices in u s dollars or local currency to averaging the data across countries versus averaging the parameters from individual country estimation and to redefining the start date of the crisis the findings endorse the use of banking regulation and capital controls as part of the policy toolkit to limit financial vulnerability

soak up the sun impact of solar energy systems on residential home values in arizona abstract recent increase of installations of solar energy systems on residential properties begs the question of whether such investments are being recognized by the market studies that estimate the impact of solar technologies on home values have been scarce using transaction and valuation data for a sample of residential properties in arizona and matching methodology results show that solar photovoltaics installation indeed has positive impacts on both house value and transaction prices this is the first empirical study conducted in arizona a state of crucial importance for solar energy development with its abundant solar resources in particular properties with electricity generating solar panels enjoy an average premium of approximately 45 000 15 of medium home value and transaction price premium of 28 000 17 of medium home sales price we do not find a statistically significant premium on homes with solar water heaters alone

current account balance and dollar standard exploring the linkages abstract this paper examines whether the international role of the dollar as main global reserve currency has contributed to persistent current account imbalances to this end we analyse how central banks accumulation of reserve assets affects the current account balance of both reserve accumulating and reserve providing countries based on a simple portfolio balance model we show theoretically that the global demand for reserve assets by central banks may lower the current account balance of the reserve issuing country our panel data analysis over the period 1970 2009 confirms this hypothesis any dollar of provided reserve assets decreases the us current account by more than one dollar on average the demand for dollar reserves has lowered the us current account by 1 2 percentage points relative to gdp the flip side of this effect is a higher current account balance in reserve accumulating countries these novel findings show that the worldwide demand for international reserves has contributed to the buildup of global imbalances

did foreign exchange holding influence growth performance during the global financial crisis in a context of increased foreign exchange reserves holding from emerging and developing countries this paper investigates the diminishing return of reserves holding assumption over the most severe phase of the global financial crisis 2008q1 2010q4 relying on a panel smooth transition regression model we highlight the differential effect of the accumulation of foreign exchange reserves for a set of financial vulnerabilities variables specifically while reserve accumulation is effective above a critical threshold to cope with vulnerabilities related to the financial channel we show that it becomes less effective beyond a certain threshold for domestic bank vulnerabilities

macroeconomic factors and microlevel bank behavior we analyze the link between banks and the macroeconomy using a model that extends a macroeconomic var for the u s with a set of factors summarizing conditions in about 1 500 commercial banks we investigate how macroeconomic shocks are transmitted to individual banks and obtain the following main findings backward looking risk of a representative bank declines and bank lending increases following expansionary shocks forward looking risk increases following an expansionary monetary policy shock there is however substantial heterogeneity in the transmission of macroeconomic shocks which is due to bank size capitalization liquidity risk and the exposure to real estate and consumer loans

can leading indicators assess country vulnerability evidence from the 2008 09 global financial crisis abstract we investigate whether leading indicators can help explain the cross country incidence of the 2008 09 financial crisis rather than looking for indicators with specific relevance to the recent crisis the selection of variables is driven by an extensive review of more than eighty papers from the previous literature on early warning indicators our motivation is to address suspicions that indicators found to be useful predictors in one round of crises are typically not useful to predict the next round the review suggests that central bank reserves and past movements in the real exchange rate were the two leading indicators that had proven the most useful in explaining crisis incidence across different countries and episodes in the past for the 2008 09 crisis we use six different variables to measure crisis incidence drops in gdp and industrial production currency depreciation stock market performance reserve losses and participation in an imf program we find that the level of reserves in 2007 appears as a consistent and statistically significant leading indicator of who got hit by the 2008 09 crisis in line with the conclusions of the pre 2008 literature in addition to reserves recent real appreciation is a statistically significant predictor of devaluation and of a measure of exchange market pressure during the current crisis we define the period of the global financial shock as running from late 2008 to early 2009 which probably explains why we find stronger results than earlier papers such as obstfeld et al 2009 2010 and rose and spiegel 2009a b 2010 2011 which use annual data

energy efficient housing stimulus that pays for itself abstract this paper describes an energy efficient housing stimulus strategy that can 1 quickly provide large scale job creation 2 reduce home energy bills by 30 50 with associated reductions in emissions and energy assistance spending 3 stabilize home values and reduce foreclosure inventory 4 help to eliminate childhood lead poisoning and 5 implement regulatory reforms that highlight market incentives for cost effective energy efficiency and alternative home energy investments these benefits far in excess of costs can be achieved by combining lead safe window replacement with other weatherization activities and simple regulatory and market reforms this strategy can help to coordinate american recovery and reinvestment act funding for energy efficiency the 75 billion making home affordable plan to reduce foreclosures and the recently announced partnership between the departments of energy doe and housing and urban development hud to streamline weatherization efforts and spur job creation

leading indicators of crisis incidence evidence from developed countries abstract we examine which indicators are most useful in explaining the cost of economic crises in eu and oecd countries between 1970 and 2010 to define the dependent variable we combine a measure of costs to the economy which consists of the output and employment loss and the fiscal deficit with a database of crisis occurrence designed specifically for this task we take into account model uncertainty in two steps first for each potential leading indicator we select the relevant prediction horizon by using panel vector autoregression second we identify the most useful leading indicators with bayesian model averaging our results suggest that domestic housing prices share prices and credit growth and some global variables such as private credit constitute important sources of risk

post mortem examination of the international financial network abstract as the recent crisis has forcefully suggested understanding financial market interconnectedness is of a paramount importance to explain systemic risk stability and economic dynamics in this paper we address these issues along two related perspectives first we explore the statistical properties of the international financial network ifn defined as a weighted directed graph where nodes are countries and links represent debtor creditor relationships in equities and short long run debt we investigate whether the 2008 financial crisis has resulted in a significant change in the topological properties of the ifn our findings suggest that the crisis caused not only a reduction in the amount of securities traded but also induced changes in the topology of the network and in the time evolution of its statistical properties this has happened however without changing the disassortative core periphery structure of the ifn architecture second we perform an econometric study to examine the ability of network based measures to explain cross country differences in crisis intensity we investigate whether the conclusion of previous studies showing that international connectedness is not a relevant predictor of crisis intensity may be reversed once one explicitly accounts for the position of each country within the ifn we show that higher interconnectedness reduces the severity of the crisis as it allows adverse shocks to dissipate quicker however being central in the network may make countries that are not members of a rich club more vulnerable in times of crisis finally we find strong evidence of nonlinear effects once the high degree of heterogeneity that characterizes the ifn is taken into account

capital and credit market integration and real economic contagion during the global financial crisis abstract this study investigates the role of financial integration in the spread of global financial crisis in particular this study shows how the effect of the crisis on real business cycle co movement varied for capital and credit market integration using a sample of 58 countries in 2001 2013 during the global financial crisis the united states the epicenter of the crisis experienced a severe downturn in the real economy and other countries followed suit we find that during the global financial crisis the business cycle co movements between the united states and the rest of the world were stronger when the level of capital market integration between them was higher however the co movements were weaker when the level of credit market integration was higher these findings are robust even when including investment channels local fundamental factors endogenous policy responses across countries and alternative measures for financial integration and business cycle co movements

optimal bidding in auctions from a game theory perspective abstract the game theoretic perspective in auction bidding has provided a powerful normative framework for the analysis of auctions and it has generated an impressive volume of research contributions tracing this research we review key recent advances which have greatly expanded our understanding of the operation of auctions and produced a more accurate analysis of mechanism design and optimal bidding we follow various experimental studies which have shown that the predictive power of auction theory remains in many cases limited for this reason we concentrate on research themes which enhance the applicability of auction theory leading to more realistic descriptions of bidding behaviors we identify important innovations which expand the environment of auction bidding and carry us beyond rational decision making we conclude providing directions of future research and discussing their implications

a decision support framework for evaluating revenue performance in sequential purchase contexts abstract this paper studies the product ordering problem in sequential purchase contexts where sellers aim to maximize their revenue faced with budget constrained buyers we propose a multi layered decision support framework that combines empirical data with simulation optimization and econometric methods to address this problem our framework allows sellers to i compare revenue performances of limited information sequencing strategies ii quantify benchmark revenue levels that can be achieved via the optimal sequence based on detailed buyer information iii determine the costs of limited information and strategic buyers to the seller and iv identify the moderators of sequencing strategy performance we illustrate our framework through two applications in a business to business used car auction setting contrary to previous studies reporting practitioners tendency to sequence items from the lowest value to the highest our results suggest that the best performing limited information sequencing strategy depends on buyers bidding behavior we also find that the revenue difference between the optimal sequence and a limited information sequencing strategy can be substantial our results show that a significant portion of this revenue difference is associated with the seller s limited information on buyers budgets and product valuations our applications also provide various sensitivity analyses and develop new propositions on the moderators of the relationship between the seller s revenue and sequencing strategies

the antecedents and aftermath of financial crises as told by carlos f diaz alejandro some of the best known papers of carlos f diaz alejandro were about latin america s crises in the 1980s and 1930s i show data figures and evidence about the crises in the advanced economies thirty years later that fit the same narrative his unadulterated words aptly describe modern problems across geographical borders and in this case income levels this attests to his timeless insight and understanding because some of the observations he made have general applicability to the study of recurring patterns across crises i have taken the liberty to label these lessons these are primarily lessons about what to avoid

risk management and dynamic network performance an illustration using a dual banking system abstractthis study applies dynamic network data envelopment analysis to compare a dual banking system namely conventional and islamic banks with emphasis on risk measures non oriented variable return to scale dynamic network slacks based measure is used to model the banking performance for the period 2008 2012 under the consideration of risk measures the findings highlight that islamic banks excel in managerial efficiency while conventional banks surpass in profitability efficiency furthermore the regression results find that the number of directors on the risk management committee has a positive impact on banking performance meanwhile the high number of independent directors improves the profitability efficiency but worsens the managerial efficiency

compact bid languages and core pricing in large multi item auctions we introduce an auction design framework for large markets with hundreds of items and complex bidder preferences such markets typically lead to computationally hard allocation problems our new framework consists of compact bid languages for sealed bid auctions and methods to compute second price rules such as the vickrey clarke groves or bidder optimal core selecting payment rules when the optimality of the allocation problem cannot be guaranteed to demonstrate the efficacy of the approach for a specific complex market we introduce a compact bidding language for tv advertising markets and investigate the resulting winner determination problem and the computation of core payments for realistic instances of the respective winner determination problems very good solutions with a small integrality gap can be found quickly although closing the integrality gap to find marginally better solutions or prove optimality can take a prohibitively large amount of time our subsequent adaptation of a constraint

for a few dollars more reserves and growth in times of crises abstract based on a dataset of 112 emerging economies and developing countries this paper addresses the question whether the accumulation of international reserves has effectively protected countries during the 2008 09 financial crisis more specifically the paper investigates the relation between international reserves and the existence of capital controls we find that the level of reserves matters countries with high reserves relative to short term debt suffered less from the crisis particularly when associated with a less open capital account this suggests some degree of complementarity between reserve accumulation and capital controls

an efficient dynamic auction for heterogeneous commodities this paper proposes a new dynamic design for auctioning multiple heterogeneous commodities generalizing earlier work that treated identical objects an auctioneer wishes to allocate one or more units of each of k heterogeneous commodities to n bidders the auctioneer announces a vector of current prices bidders report back quantities demanded at these prices and the auctioneer adjusts the prices units are credited to bidders at the current prices as their opponents demands decline and the process continues until every commodity market clears bidders rather than being required to behave as price takers are permitted to strategically exercise their market power nevertheless with pure private values the proposed auction yields walrasian equilibrium prices an efficient outcome results as from a vickrey clarke groves mechanism but bidders are only required to evaluate their demands along a one dimensional path of prices rather than reporting their utilities over the entire k dimensional consumption set the auction is also more transparent and potentially simpler for bidders to understand and has the advantage of assuring the privacy of the upper portions of bidders demands theoretically the new auction provides a new foundation for convergence to walrasian equilibrium in an exchange economy practically it provides an efficient method for simultaneously auctioning two or more related types of securities for example three month and six month treasury bills it is also potentially useful for auctioning multiple types of communications spectrum for example licenses for paired and unpaired spectrum

how central banks prepare for financial crises an empirical analysis of the effects of crises and globalisation on international reserves central banks international reserve holdings have increased significantly in the recent past while traditional models fail to explain this accumulation of reserves the more recent literature argues that reserves are used as a lifejacket against currency crises however research so far has neglected the question whether and how central banks change their precautionary reserve holdings after the country was affected by a currency crisis this paper tests the hypothesis that central banks revise their reserve policy in the aftermath of currency crises a dynamic panel data model is estimated for developing and industrial countries covering the period from 1975 to 2003 the evidence suggests that currency crises induce a permanent increase of reserves this effect is particularly strong for recent currency crises since the asian financial crisis

predicting banking crises with artificial neural networks the role of nonlinearity and heterogeneity studies of the early warning systems ewss for banking crises usually rely on linear classifiers estimated with international datasets i construct an ews based on an artificial neural network ann model and i also account for regional heterogeneity in order to improve the generalization ability of ews models all of the banking crises in my test set are then predictable at a 24 month horizon using information from earlier crises for some countries estimation with a regional dataset significantly improves the predictions the ann outperforms the usual logit regression assessed by the area under the receiver operating characteristics curve

predicting currency fluctuations and crises do resident firms have an informational advantage the authors investigate whether resident enterprise managers have an informational advantage about the countries in which they work they propose a method for extracting information available to resident managers but unknown to investors and forecasters they rest their hypothesis of informational advantage using a unique data set the global competitiveness survey the survey asks local managers about their outlook for the country in which they reside they find that local managers do have useful private information local managers responses improve on conventional forecasts of future volatility and changes in the exchange rate which are based on economic fundamentals or interest rate differentials they find that the local business community perceived in advance the recent crises in the republic of korea russia and thailand but not those in indonesia and malaysia markets have had limited success predicting crises and might do better by drawing on private information available to resident enterprise managers who seem to know better than markets about future movements in exchange rates

currency crises and institutions abstract this study furthers recent literature on currency crises and institutions the main objective is to re evaluate the causes of currency crises by focusing on the role played by a broader array of institutional factors and crisis episodes than have previously been considered while at the same time controlling for economic factors our dataset consists of over 30 countries covering 13 institutional factors for the period 1984 2002 two questions are addressed they are 1 what mix of institutions may contribute to or set the stage for a currency crisis and 2 what mix of institutions may affect the depth of currency crises as measured by a decline in output our findings reveal that institutional as well as economic factors affect the probability of currency crises and that worse institutions are associated with bigger contractions in output during the crisis in general our strongest results regarding institutions show that corruption a de facto fixed exchange rate regime weak government stability and weak law and order increase the probability of a currency crisis we find mixed evidence that deposit insurance the removal of capital controls a lack of central bank independence financial liberalization and civil law increase the chance of crisis we find a similar set of factors worsens the contraction in output during a crisis except for deposit insurance which we find moderates the contraction in output

worldwide economic recoveries from financial crises through the decades abstract the profiles of economic recoveries after a financial crisis are identified through a self organizing map covering 104 countries during 1973 2017 first and surprisingly only 55 of the 276 events belong to the usual v u l classification new s shaped bounce back recoveries d oomed ones and double dip m occur in 23 18 and 4 of the cases respectively second the frequencies of profiles vary with the crisis type countries development and location and over time third unlike government spending supporting domestic credit liquidity foreign trade or else the exchange rate after the crisis may help activity bounce back

auctions with bidder determined allowable combinations abstract combinatorial auctions are desirable as they enable bidders to express the synergistic values of a group of assets and thus may lead to better allocations compared to other types of auctions they keep bidders from being exposed to risks of receiving only parts of combinations that would be valuable to them or from being overly cautious in order to minimize such risks however computation time needed to determine the set of optimal winning combinations in a general combinatorial auction may grow exponentially as the auction size increases and this is sometimes given as a reason for not using combinatorial auctions to determine the winning allocation in a reasonable time a bid taker might try to limit the kinds of allowable combinations but bidders may disagree on what combinations should be allowed and this may make limiting the allowable combinations politically infeasible this paper proposes and tests successfully a new approach to managing the computational complexity of determining the set of winning combinations the main idea is to let bidders themselves determine and prioritize the allowable combinations using bidder determined combinations has two nice properties first by delegating the decision on what is biddable to the bidders who know what combinations are important to them the bid taker is able to be and appear fair second since bidders know their economics and have the incentive to get important combinations included bidder prioritization of combinations will tend to assure that the most economically important combinations are included in determining the winning set of bids if the bid taker is not able to consider all of the combinations submitted by bidders the proposed auction process is useful in situations such as government auctions in which the bid taker is reluctant to limit the allowable combinations

the package assignment model we study assignment problems where individuals trade packages consisting of several rather than single objects although buyers reservations values are non additive efficient assignments can be formulated as a linear programming problem in which the pricing functions expressing duality may be non linear in the objects constituting the packages the interconnections among the linear programming formulation walrasian equilibrium and the core are established in the single seller auction version a necessary and sufficient condition is given for the vickrey payoff point to be implementable by a pricing equilibrium journal of economic literature classification numbers c62 d44 d51

on ascending vickrey auctions for heterogeneous objects abstract we construct an ascending auction for heterogeneous objects by applying a primal dual algorithm to a linear program that represents the efficient allocation problem for this setting the auction assigns personalized prices to bundles and asks bidders to report their preferred bundles in each round a bidder s prices are increased when he belongs to a minimally undersupplied set of bidders this concept generalizes the notion of overdemanded sets of objects introduced by demange gale and sotomayor for the one to one assignment problem under a submodularity condition the auction implements the vickrey clarke groves outcome we show that this type of condition is somewhat necessary to do so when classifying the ascending auction literature in terms of their underlying algorithms our auction fills a gap in that literature we relate our results to various ascending auctions in the literature

currency crashes in emerging markets an empirical treatment we use a panel of annual data for over 100 developing countries from 1971 through 1992 to characterize currency crashes we define a currency crash as a large change of the nominal exchange rate that is also a substantial increase in the rate of change of nominal depreciation we examine the composition of the debt as well as its level and a variety of other macroeconomic factors external and foreign crashes tend to occur when output growth is low the growth of domestic credit is high and the level of foreign interest rates are high a low ratio of fdi to debt is consistently associated with a high likelihood of a crash

financial instability reserves and central bank swap lines in the panic of 2008 in this paper we connect the events of the last twelve months the panic of 2008 as it has been called to the demand for international reserves in previous work we have shown that international reserve demand can be rationalized by a central bank s desire to backstop the broad money supply to avert the possibility of an internal external double drain a bank run combined with capital flight thus simply looking at trade or short term debt as motivations for reserve holdings is insufficient one must also consider the size of the banking system m2 here we show that a country s reserve holdings just before the current crisis relative to their predicted holdings based on these financial motives can significantly predict exchange rate movements of both emerging and advanced countries in 2008 countries with large war chests did not depreciate and some appreciated meanwhile those who held insufficient reserves based on our metric were likely to depreciate current account balances and short term debt levels are not statistically significant predictors of depreciation once reserve levels are taken into account our model s typically high predicted reserve levels provide important context for the unprecedented u s dollar swap lines recently provided to many countries by the federal reserve this abstract was borrowed from another version of this item

economic efficiency v energy efficiency do model conservation standards make good sense abstract the incremental market value of higher thermal efficiency standards in new houses and the resulting energy savings are estimated using linear regression techniques based on the empirical findings a homebuyer discount rate is calculated and cost effectiveness tests are performed the findings indicate that the real estate market operates efficiently in capitalizing the value of energy savings into sale prices it appears that under current pricing mechanisms the thermal performance improvements provide net benefits to the homebuyer and to the sponsoring utility

ascending price vickrey auctions for general valuations ascending price auctions typically involve a single price path with buyers paying their final bid price using this traditional definition no ascending price auction can achieve the vickrey clarke groves vcg outcome for general private valuations in the combinatorial auction setting we relax this definition by allowing discounts to buyers from the final price of the auction or alternatively calculating the discounts dynamically during the auction while still maintaining a single price path using a notion called universal competitive equilibrium prices shown to be necessary and sufficient to achieve the vcg outcome using ascending price auctions we define a broad class of ascending price combinatorial auctions in which truthful bidding by buyers is an ex post nash equilibrium any auction in this class achieves the vcg outcome and ex post efficiency for general valuations we define two specific auctions in this class by generalizing two known auctions in the literature 11 24

housing market capitalization of thermal integrity abstract the extent to which housing markets capitalize investments in energy efficiency is important to observe the uncertainty now associated with this process can lead households to allocate resources inefficiently in the production of thermal comfort by substituting more fuel inputs for less capital from a policy perspective the end result of this is the continued construction of units in the housing stock with sub optimal levels of energy efficiency this study is a cross sectional analysis of houses constructed through the energy efficient housing demonstration program of the minnesota housing finance agency values of investments in energy efficiency are derived from a hedonic regression which includes a vector of thermal integrity factors as an independent variable

housing market capitalization of energy saving durable good investments energy conservation in the residential sector depends in large measure upon the willingness of builders and homeowners to invest in the durable goods which result in an energy efficient house since these durable goods generally become attached permanently to the dwelling unit and since ownership of the unit is likely to change within the expected lifetime of the installed equipment the incentive to invest in conservation measures depends upon the efficiency of the housing market in capitalizing the financial benefits of future fuel savings this paper examines housing market efficiency in this regard by first estimating an hedonic price index with the annual fuel bill included as an explicit attribute of the structure then from the estimated hedonic price of a one dollar reduction in annual fuel costs and assumed fuel price escalation rates and remaining lifetimes of the equipment implicit housing market discount rates are calculated the relatively low estimated discount rates indicate that the housing market performs efficiently in capitalizing future fuel savings

estimating the demand for the characteristics of housing a hstract estimates of the demand for the characteristics contained in a differentiated product such as housing can be based on hedonic regressions however previous studies have not dealt with several potential problems in such estimation a more appropriate framework for the estimation is provided in this paper also data from a number of cities are used to eliminate the identification problem and the endogeneity of the marginal prices derived from non linear hedonic equations is considered in the estimation the results on own and cross price elasticities expenditure elasticities and the effects of socio economic vafiables accord well with expectations

forecasting the fragility of the banking and insurance sectors linkages between banks and insurance companies are important when forecasting the fragility of the banking and insurance sectors we propose a novel empirical framework that allows us to estimate unobserved linkages in panel data sets that contain observed regressors we find that taking unobserved common factors into account reduces the root mean square forecasts error of firm specific forecasts by up to 9 of system forecasts by up to 14 and by up to 39 for systemic forecasts of more distressed firms relative to a model based on observed variables only estimates of the factor loadings suggest that the correlation of financial institutions has been relatively stable over the forecast period

explaining the duration of exchange rate pegs abstract this paper is an empirical investigation of the duration of exchange rate pegs in 16 latin american countries and jamaica we identify factors that influence peg duration using logit analysis the real exchange rate and the level of international liquidity are significant determinants of the monthly likelihood of devaluation structural variables such as the openness of an economy and its geographical trade concentration and political variables such as changes in the executive also significantly affect the likelihood of a devaluation there is some evidence that the likelihood of a devaluation first rises and subsequently declines during the first year of a peg

the determinants of vulnerability to the global financial crisis 2008 to 2009 credit growth and other sources of risk abstract in this paper we identify initial macroeconomic and financial market conditions that help explain the distinct response of the real economy of a particular country to the recent global financial crisis using four measures of crisis severity we examine a data set with over 90 potential explanatory factors employing techniques that are robust to model uncertainty four findings are of particular note first we find empirical evidence for the pivotal role of pre crisis credit growth in shaping the real economy s response to the crisis specifically a 1 increase in pre crisis lending translates into a 0 2 increase in the cumulative loss in real output moreover the combination of pronounced growth in lending ahead of the crisis and the country s exposure to external funding from advanced economies is shown to intensify the real downturn economies with booming real activity before the crisis are found to be less resilient to the global shock buoyant growth in real gdp in parallel with strong growth of credit particularly exacerbated the effects of the recent crisis on the real economy finally we provide empirical evidence on the importance of holding international reserves in explaining the response of the real economy to the crisis the accumulation of international reserves mitigated the harmful effects of financial stress on the real economy in particular when domestic funding via credit is abundant the results are shown to be robust to several estimation techniques including those allowing for cross country spillovers

financial crises lessons from history for today making use of the propensity score matching method we match earlier crises pre 2007 with currently ongoing crises post 2007 the old and new crises are matched in three dimensions the global setting in which they occurred the structure of the economy and the domestic vulnerabilities in the pre crisis period our findings suggest that the euro periphery crises share sufficient commonalities with earlier crises in their pre crisis domestic vulnerabilities the study points to two important conclusions first the euro periphery crises are composed of unique country experiences hence it will not be easily resolved with a one size fits all set of economic policies secondly while each banking crisis has its inherent uniqueness each crisis also shares sufficient commonalities with one or more of the asian 5 1996 97 crises the nordic banking crisis of the early 1990s or the japanese banking crisis of the 1990s thus the extensive knowledge accumulated through these former banking crises can help in designing recovery policies selin sayek and fatma taskin

financial indicators signaling correlation changes in sovereign bond markets abstract we use a smooth transition conditional correlation garch stcc garch model applied to the euro area monetary policy rates and sovereign yields of italy spain and germany at 5 year maturity to estimate the threshold level of the signals above which the sovereign bond market moves to a crisis regime we show that the threshold to a crisis regime for italy and spain is reached when i their 5 year sovereign yield spreads amount to about 90 basis points ii their 5 year cds spreads amount to about 155 basis points or iii the 5 year spread between the kreditanstalt fur wiederaufbau kfw bond and the german bund amounts to about 30 40 basis points using impulse responses we find that the stcc garch with the kfw bund spread has leading properties a feature corroborated by the fact that this indicator suggested a shift to a crisis regime already in august 2007 and has been signaling an improvement of the situation already in the autumn of 2012 an out of sample forecast of the stcc garch model is also provided which is both a novelty and a further robustness check for the stability of the model

reserve accumulation and financial crises from individual protection to systemic risk abstract this paper provides a new perspective on the relationship between countries international reserve holdings and financial crises while the local view holds that reserves may prevent domestic crises it overlooks that the accumulation of reserves relaxes the financing constraint of the reserve currency country and may cause a financial crisis in the centre which is transmitted globally according to this global view reserve accumulation might destabilize the international financial system since the crisis affects all countries alike the accumulation of reserves imposes a negative externality on non accumulating countries we integrate this idea in a theoretical model of the optimal amount of reserves and illustrate the gap between local and global optimality the consideration of systemic risk lowers the demand for reserves moreover if a supranational authority determines the optimal level of reserves it internalizes the negative externality and accumulates fewer reserves a macroprudential tax on reserve hoardings might implement the socially optimal solution our calibration analysis shows that these considerations are economically significant they lower the optimal amount of reserves in the benchmark case by 45

simultaneity in the market for housing characteristics abstract the nature of simultaneity in the markets for housing characteristics is examined simultaneity is found to arise in the implicit markets for individual characteristics because of the presence of nonlinearity in the market hedonic price function for housing however this simultaneity is not the kind discussed by s rosen j political econ 82 34 55 1974 between firm supplies and household demands as a result the rosen suggestion of identifying demand with firm supply shifters is inappropriate among the alternative approaches to identification the most desirable involve use of data over two or more markets in which residence for a given household is exogenous to the choice of housing

cross country experiences and policy implications from the global financial crisis the financial crisis of 2007 2008 is rooted in a number of factors some common to previous financial crises others new analysis of post crisis macroeconomic and financial sector performance for 58 advanced countries and emerging markets shows a differential impact of old and new factors factors common to other crises like asset price bubbles and current account deficits help to explain cross country differences in the severity of real economic impacts new factors such as increased financial integration and dependence on wholesale funding help to account for the amplification and global spread of the financial crisis our findings point to vulnerabilities to be monitored and areas of needed national and international reforms to reduce risk of future crises and cross border spillovers they also reinforce a sad state of knowledge much of how crises start and spread remains unknown stijn claessens giovanni dell ariccia deniz igan and luc laeven

the impact of energy prices a housing market analysis abstract this paper investigates the effect of energy costs on the housing market response as the effect of energy costs has not been specifically investigated before in the literature both a linear and non linear model were investigated the choice of the appropriate model was determined using the box cox transformation technique the chosen model was then validated the results reveal that in the spokane washington area where energy costs are relatively low energy prices do not have a significant effect on market response however applying the same methodology to areas where energy costs are higher might produce different results

international reserves and the maturity of external debt abstract this paper studies how the level of international reserves affects the maturity structure of external debt we show in an illustrative theoretical model that reserves lengthen the maturity of external debt via a flattening of the yield curve using data of 66 emerging and developing countries and applying different econometric approaches we find robust evidence that reserves increase the share of long term in total external debt results hold for private and public external debt individually taking reserves and their effect on the debt maturity structure together they reinforce financial stability

currency crises are they all the same abstract the plethora of currency crises around the world has fueled many theories on the causes of speculative attacks the first generation models focus on fiscal problems while the second generation models emphasize countercyclical policies and self fulfilling crises in the 1990s models pinpoint to financial excesses with the crisis of argentina in 2001 models of sovereign default have become popular again while the theoretical literature has emphasized variety the empirical literature has supported the one size fits all models this paper contributes to the empirical literature by assessing whether the crises of the last 30 years are of different varieties

explaining the transition between exchange rate regimes this paper studies the transition between exchange rate regimes using a markov chain model with time varying transition probabilities the probabilities are parameterized as nonlinear functions of variables suggested by the currency crisis and optimal currency area literature results using annual data indicate that inflation and to a lesser extent output growth and trade openness help explain the exchange rate regime transition dynamics

a new and improved design for multiobject iterative auctions in this paper we present a new improved design for multiobject auctions and report on the results of experimental tests of that design we merge the better features of two extant but very different auction processes the simultaneous multiple round smr design used by the fcc to auction the electromagnetic spectrum and the adaptive user selection mechanism ausm of banks et al 1989 allocating uncertain and unresponsive resources an experimental approach rand journal of economics vol 20 no 1 pp 1 25 then by adding one crucial new feature we are able to create a new design the resource allocation design rad auction process which performs better than both our experiments demonstrate that the rad auction achieves higher efficiencies lower bidder losses higher net revenues and faster times to completion without increasing the complexity of a bidder s problem

analyzing industry level vulnerability by predicting financial bankruptcy this study introduces a novel framework for building company bankruptcy models and a methodology for assessing the vulnerability of industrial economic activities we consider the identification of bankruptcy as a classification problem and assume that bankruptcy criteria differ across industries we build highly accurate industry bankruptcy models by constructing separate models for each industry we also propose a method of analyzing the vulnerability of industrial economic activities in various countries and industries using new indicators we call expected potential loss which we obtain using the predicted likelihood of bankruptcy and company information jel g0 c0

iterative combinatorial auctions with bidder determined combinations in combinatorial auctions multiple distinct items are sold simultaneously and a bidder may place a single bid on a set package of distinct items the determination of packages for bidding is a nontrivial task and existing efficient formats require that bidders know the set of packages and or their valuations in this paper we extend an efficient ascending combinatorial auction mechanism to use approximate single item pricing the single item prices in each round are derived from a linear program that is constructed to reflect the current allocation of packages introduction of approximate single item prices allows for endogenous bid determination where bidders can discover packages that were not included in the original bid set due to nonconvexities single item prices may not exist that are exact marginal values we show that the use of approximate single item prices with endogenous bidding always produces allocations that are at least as efficient as those from bidding with a fixed set of packages based on package pricing a network resource allocation example is given that illustrates the benefits of our endogenous bidding mechanism

do weak institutions prolong crises on the identification characteristics and duration of declines during economic slumps this paper studies periods of prolonged contractions in output per capita in a sample of 145 countries from 1950 to 2014 economic slumps are defined as abrupt interruptions of a period of growth by several regime switches slumps start with a sharp contraction along with a trend break which is followed by another switch when growth stabilizes again the paper then analyzes the correlates of these slumps focusing on the length and depth of the contraction from the beginning of the slump to its trough the results establish three new stylized facts i weak political institutions predate crises whereas political reforms tend to follow them ii the length and depth of economic declines are robustly correlated with executive constraints and ethnic heterogeneity and iii there is a robust interaction between these two variables suggesting that institutions constraining leaders are important for stabilizing growth this is particularly relevant for sub saharan africa where politics are often ethnic and decision makers are comparatively unconstrained

multi object auctions with package bidding an experimental comparison of vickrey and ibea abstract the use of package auctions for complex resource allocation has been rapidly increasing in recent years in this paper we study two package auction mechanisms in a laboratory setting a sealed bid vickrey auction and an ascending version of vickrey the i bea auction unlike the single unit vickrey auction where bidders tend to overbid in the laboratory most of our bidders either underbid or bid their true values furthermore at the aggregate level while the vickrey auction generates significantly higher revenue than does i bea the i bea auction generates significantly higher bidder profit and efficiency additionally a significantly larger proportion of i bea auctions achieves 100 efficiency than does the vickrey auction we also find that human bidders learn from their robot opponents when the robot strategies are myopic best responses

predicting financial crises the statistical significance of the signals approach abstract the signals approach as an early warning system has been fairly successful in detecting crises but it has so far failed to gain popularity in the scientific community because it cannot distinguish between randomly achieved in sample fit and true predictive power to overcome this obstacle we test the null hypothesis of no correlation between indicators and crisis probability in three applications of the signals approach to different crisis types to that end we propose bootstraps specifically tailored to the characteristics of the respective datasets we find 1 that previous applications of the signals approach yield economically meaningful results 2 that composite indicators aggregating information contained in individual indicators add value to the signals approach and 3 that indicators which are found to be significant in sample usually perform similarly well out of sample

leading indicators of fiscal distress evidence from extreme bounds analysis early warning systems ewss are widely used to assess a country s vulnerability to fiscal distress a fiscal distress episode is identified as a period when government experiences extreme funding

towards a new early warning system of financial crises abstract this paper develops a new early warning system ews model based on a multinomial logit model for predicting financial crises it is shown that commonly used ews approaches which use binomial discrete dependent variable models are subject to what we call a post crisis bias this bias arises when no distinction is made between tranquil periods when economic fundamentals are largely sound and sustainable and crisis post crisis periods when economic variables go through an adjustment process before reaching a more sustainable level or growth path we show that applying a multinomial logit model which allows distinguishing between more than two states is a valid way of solving this problem and constitutes a substantial improvement in the ability to forecast financial crises the empirical results reveal that for a set of 20 open emerging markets for the period 1993 2001 the model would have correctly predicted a large majority of crises in emerging markets

allocative efficiency of markets with zero intelligence traders market as a partial substitute for individual rationality we report market experiments in which human traders are replaced by zero intelligence programs that submit random bids and offers imposing a budget constraint i e not permitting traders to sell below their costs or buy above their values is sufficient to raise the allocative efficiency of these auctions close to 100 percent allocative efficiency of a double auction derives largely from its structure independent of traders motivation intelligence or learning adam smith s invisible hand may be more powerful than some may have thought it can generate aggregate rationality not only from individual rationality but also from individual irrationality

exchange rate regimes and the cross country distribution of the 1997 financial crisis robin m grier we study variations in the severity of the 1997 financial crisis in a sample of 25 developing countries we use both currency depreciation and stock market returns as crisis measures our key findings are that countries that started 1997 with an exchange rate peg experienced significantly greater currency depreciation and significantly lower stock returns than would be predicted from the levels of various macroeconomic indicators jel f3 f4 i introduction the asian financial crisis of 1997 is still a very hot topic a recent search of econlit turned up 243 articles in the system with asian crisis in the subject field 1 several recent articles attempt to explain variations in the severity of the crisis across developing countries using macroeconomic and financial variables and show that the distribution of the crisis is somewhat predictable our article extends this literature in two directions first we examine whether the initial exchange rate regime in place at the beginning of 1997 had any effect on the distribution of the financial crisis once the relevant macro and financial indicators are included in the model second given that a real crisis followed on the heels of the financial one we study the relationship between exchange rate regime currency depreciation and stock market performance in 1997 our sample consists of 25 developing countries in 1997 2 though a cross sectional approach limits the generality of our results we believe we can ask and answer two interesting questions about the average performance of different exchange rate regimes in 1997 the first question is controlling for economic indicators what was the average effect of having an initially pegged exchange rate on currency depreciation there are theoretical arguments presented in section ii that can justify either positive negative or zero effects we find that on average countries with a pegged regime at the beginning of the year experienced more depreciation than what was predicted by their macro indicators the second question we study is what was the average effect of currency depreciation on stock market performance in 1997 again there are arguments presented in section iii supporting either a positive negative or neutral relationship we find that on average depreciation has a marginally significant negative impact on stock returns however in the 12 countries that began 1997 with a floating exchange rate currency depreciation had a significantly positive effect on stock returns whereas the effect of depreciation on stock returns was negative and significant for the 13 countries that started the year with a pegged currency this relationship holds for stock returns measured either in u s dollars or in local currencies the papers most similar to ours in the literature are tornell and velasco 1995 edwards 1993 corsetti et al 1999 hereafter cpr and tornell 1999 tornell and velasco and edwards study whether or not the choice of exchange rate regime affects economic outcomes 3 cpr and tornell study the asian financial crisis of 1997 in the broader context of developing country performance they create a crisis index and estimate several regressions using macro and financial indicators to predict the extent of the crisis in a sample of developing countries our article applies the idea that the choice of exchange rate regime can affect macroeconomic and financial outcomes to the study of the determinants of the severity of the 1997 crisis in a model similar to those of cpr and tornell in what follows below section ii studies the relationship between macro and financial indicators the initial exchange rate regime and currency depreciation in 1997 section iii considers the depreciation exchange rate regime stock market connection in 1997 section iv presents our conclusions ii macro indicators currency depreciation and exchange rate regime in 1997 the question of what exactly determines the value of the exchange rate is an important unsolved issue in open economy macroeconomics and we are not going to settle it here

cross country causes and consequences of the crisis an update abstract we update rose and spiegel forthcoming rose and spiegel 2010 and search for simple quantitative models of macroeconomic and financial indicators of the great recession of 2008 09 we use a cross country approach and examine a number of potential causes that have been found to be successful indicators of crisis intensity by other scholars we check a number of different indicators of crisis intensity and a variety of different country samples while countries with higher income and looser credit market regulation seemed to suffer worse crises we find few clear reliable indicators in the pre crisis data of the incidence of the great recession countries with current account surpluses seemed better insulated from slowdowns

predicting currency crises abstract in recent years a number of researchers have claimed success in systematically predicting which countries are more likely to suffer currency crises most notably kaminsky lizondo and reinhart 1998 this paper evaluates the klr approach to anticipating currency crises and develops and tests an alternative first we try to answer the question if we had been using the klr model in late 1996 how well armed would we have been to predict the asia crisis second we analyze a more general probit based model of predicting currency crises in the process we test several basic assumptions underlying the indicators approach

exchange market mayhem the antecedents and aftermath of speculative attacks exchange market mayhem the antecedents and aftermath of speculative attacks this paper evaluates the causes and consequences of episodes of turbulence in foreign exchange markets using data from 1959 through 1993 for twenty oecd countries we consider the antecedents and aftermath of devaluations and revaluations flotations fixings and speculative attacks which may not be successful we find that realignments of fixed exchange rates are alike devaluations are preceded by political instability budget and current account deficits and fast growth of money and prices revaluations are mirror images of devaluations speculative attacks resemble devaluations but money growth and inflation are more endemic and there is no last minute attempt to tighten monetary policy in contrast few consistent correlations link regime transitions like flotations or fixings to macroeconomic or political variables transitions between exchange rate regimes are largely idiosyncratic and are neither consistently provoked ex ante by systematic imbalances nor typically justified ex post by subsequent changes in policy we conclude that there are no clear early warning signals of many speculative attacks and no easy solutions for policy makers barry eichengreen andrew k rose and charles wyplosz

hedonic prices property values and measuring environmental benefits a survey of the issues this paper provides a review of the theoretical basis and the assumptions required in order to use hedonic price equations derived from property value data to obtain measures of the prices and the inverse demand functions for environmental amenities such as air quality it also includes a review and assessment of existing empirical applications of the technique to problems of air and water quality and urban noise

are currency crises predictable abstract this paper studies whether exchange rate expectations and overvaluations are predictors of currency crises the results suggest that overvaluation has predictive power in explaining the crises however although expected depreciation obtained from survey data partially takes different exchange rate misalignment measures into consideration expectations fail to anticipate currency crises

a cardan s discriminant approach to predicting currency crashes abstract this paper models large swings in exchange rates by introducing nonlinearity via the generalized normal gen distribution lye j n martin v l 1993 robust estimation nonnormalities and generalized exponential distributions journal of the american statistical association 88 261 267 as the distribution allows for bimodality a switch between modes may give rise to currency crashes a statistic known as cardan s discriminant based on the shape parameters of the gen is used to detect bimodality the cardan s discriminant is found to reliably predict currency crashes for eight emerging countries and generate relatively low false signals for stable currencies

foreign effects of higher u s interest rates abstract this paper analyzes the spillovers of higher u s interest rates on economic activity in a large panel of 50 advanced and emerging economies we allow the response of gdp in each country to vary according to its exchange rate regime trade openness and a vulnerability index that includes current account foreign reserves inflation and external debt we document large heterogeneity in the response of advanced and emerging economies to u s interest rate surprises in response to a u s monetary tightening gdp in foreign economies drops about as much as it does in the united states with a larger decline in emerging economies than in advanced economies in advanced economies trade openness with the united states and the exchange rate regime account for a large portion of the contraction in activity in emerging economies the responses do not depend on the exchange rate regime or trade openness but are larger when vulnerability is high

what is really common in the run up to banking crises abstract arguing that crises are similar if they are predictable from historical experience we employ panel logit models to examine similarities in the run ups to the current global financial crisis and historical banking crises asset bubbles are the most common precursors

did established early warning signals predict the 2008 crises abstract over the past 60 years a voluminous literature has painstakingly developed crises theories and their associated early warning signals the hallmark of this literature is the consistency with which selected early warning signals such as the level of reserves and exchange rate appreciations are presumed to predict different types of crises across countries and time the diversity of crises theories that motivate early warning signals presents however a challenge to empirical implementations given that the true model of early warning signals is unknown omitted variable bias contaminates estimates and confidence levels when the uncertainty surrounding a particular theory has been ignored after addressing model uncertainty in early warning signal regressions using an extended version of frankel and saravelos 2012 j int econ 87 216 231 dataset we do not find a single early warning signal that alerts to all dimensions of the 2008 crisis instead distinct sets of early warning signals identify different dimensions of the crisis banking balance of payments exchange rate pressure and recession

developing an early warning system to predict currency crises abstract the purpose of this paper is to develop an early warning system to predict currency crises in this study a data set covering the period of january 1992 december 2011 of turkish economy is used and an early warning system is developed with artificial neural networks ann decision trees and logistic regression models financial pressure index fpi is an aggregated value composed of the percentage changes in dollar exchange rate gross foreign exchange reserves of the central bank and overnight interest rate in this study fpi is the dependent variable and thirty two macroeconomic indicators are the independent variables three models which are tested in turkish crisis cases have given clear signals that predicted the 1994 and 2001 crises 12 months earlier considering all three prediction model results turkey s economy is not expected to have a currency crisis ceteris paribus until the end of 2012 this study presents uniqueness in that decision support model developed in this study uses basic macroeconomic indicators to predict crises up to a year before they actually happened with an accuracy rate of approximately 95 it also ranks the leading factors of currency crisis with regard to their importance in predicting the crisis

the impacts of energy efficiency policies meta analysis abstract this paper attempts to quantitatively summarize the existing empirical evidence on the effects of energy efficiency policies on energy demand and on the price of associated durable goods as well as to identify the main factors that systematically affect the estimated impacts to this end a meta regression analysis of the effects of energy efficiency policies is carried out on the basis of an extensive review of the existing literature selecting those studies that analyze the impact of energy efficiency policies with respect to a business as usual setting taking into account the econometric problems associated with this type of analysis intra class correlation cross sectional dependence publication bias in pursuit of robust outcomes the results show that the studies analyzing the effects of energy efficiency policies estimate a significant impact of these policies on energy demand 10 5 8 8 and the price of related durable goods 7 9 6 the main factors that influence results are the policy instrument the targeted sector the type of country the analyzed period the consideration of free riders and the type of analysis data and publication energy demand and the sector and analyzed period price of durables

on the robustness of non linear personalized price combinatorial auctions abstract though the vcg auction assumes a central place in the mechanism design literature there are a number of reasons for favoring iterative combinatorial auctions icas several promising ica formats were developed based on primal dual and subgradient algorithms prices are interpreted as a feasible dual solution and the provisional allocation is interpreted as a feasible primal solution ibundle 3 dvsv and ascending proxy auction result in vcg payoffs when the coalitional value function satisfies buyer submodularity and bidders bid straightforward which is an ex post nash equilibrium in this case ibea and creditdebit auctions do not even require the buyer submodularity and achieve the same properties for general valuations often however one cannot assume straightforward bidding and it is not clear from the theory how these non linear personalized price auctions nlppas perform in this case robustness of auctions with respect to different bidding behavior is a critical issue for any application we conducted a large number of computational experiments to analyze the performance of nlppas with respect to different bidding strategies and valuation models we compare nlppas with the vcg auction and with icas with linear prices such as alps and the combinatorial clock auction while nlppas performed very well in case of straightforward bidding we observe problems with revenue efficiency and speed of convergence when bidders deviate

a trading mechanism contingent on several indices we introduce a trading mechanism where the execution of an order on a security can be made contingent on the relation between the clearing price of the security and the clearing price of one or several indices a mechanism similar to ours but limited to only one index was implemented on the tel aviv stock exchange we argue that it is in some cases crucial to make the execution of an order contingent on several indices our mechanism consists of a particular implementation of a double sided multi unit combinatorial auction with substitutes or dmcs auction which we introduced in an earlier article
