international and historical dimensions of the financial crisis of 2007 and 2008 abstract this article provides an interpretative overview of the papers in this special issue of jimf devoted to international aspects of the 2007 2009 financial crisis it then goes on to provide additional empirical evidence of two sorts the first documents the difference between the monetary policies pursued by the european central bank the bank of japan the bank of england and the federal reserve in this episode and the policies pursued by the federal reserve in the great depression in the course of this episode unlike the great depression policies were not contractionary and the recessions were less severe than in the united states in 1929 1933 the second compares the recovery in the united states in the aftermath of the recent crisis and in recoveries following periods of previous banking crises this recovery is much weaker than average

optimal dynamic pricing of inventories with stochastic demand over finite horizons in many industries managers face the problem of selling a given stock of items by a deadline we investigate the problem of dynamically pricing such inventories when demand is price sensitive and stochastic and the firm s objective is to maximize expected revenues examples that fit this framework include retailers selling fashion and seasonal goods and the travel and leisure industry which markets space such as seats on airline flights cabins on vacation cruises and rooms in hotels that become worthless if not sold by a specific time we formulate this problem using intensity control and obtain structural monotonicity results for the optimal intensity resp price as a function of the stock level and the length of the horizon for a particular exponential family of demand functions we find the optimal pricing policy in closed form for general demand functions we find an upper bound on the expected revenue based on analyzing the deterministic version of the problem and use this bound to prove that simple fixed price policies are asymptotically optimal as the volume of expected sales tends to infinity finally we extend our results to the case where demand is compound poisson only a finite number of prices is allowed the demand rate is time varying holding costs are incurred and cash flows are discounted the initial stock is a decision variable and reordering overbooking and random cancellations are allowed

revenue management with strategic customers last minute selling and opaque selling companies in a variety of industries e g airlines hotels theaters often use last minute sales to dispose of unsold capacity although this may generate incremental revenues in the short term

the global financial crisis explaining cross country differences in the output impact abstract what explains differences in the crisis impact across developing countries and emerging markets using cross country regressions to assess the factors driving the growth performance in 2009 compared to pre crisis forecasts for that year we find that a small set of variables explain a large share of the variation in the growth impact countries with more leveraged domestic financial systems stronger credit growth and more short term debt tended to suffer a larger effect on economic activity although the relative importance of these factors differs across country groups for emerging markets this financial channel trumps the trade channel for a broader set of developing countries however the trade channel seems to have mattered with more open countries affected more strongly and those exporting food commodities being less hard hit exchange rate flexibility helped in buffering the impact of the shock particularly for emerging markets there is also some evidence that countries with a stronger fiscal position prior to the crisis were impacted less severely we find little evidence for the importance of other policy variables

the hidden information content of price movements dynamic patterns of prices in different markets may motivate strategic consumers who could be monitoring price movements over time to game vendors do past price movements carry information about the probability and magnitude of future price drops conducting empirical work in the airline industry on near 1000 us domestic routes we find that some price metrics carry information about future price swings these variables can assist in predicting the likelihood and magnitude of price drops these price metrics yield significantly different signals which also vary as the prediction horizon changes

sulfur dioxide control by electric utilities what are the gains from trade title iv of the 1990 clean air act amendments caaa established a market for transferable sulfur dioxide so2 emission allowances among electric utilities this market offers firms facing high marginal abatement costs the opportunity to purchase the right to emit so2 from firms with lower costs and this is expected to yield cost savings compared to a command and control approach to environmental regulation this paper uses econometrically estimated marginal abatement cost functions for power plants affected by title iv of the caaa to evaluate the performance of the so2 allowance market specifically we investigate whether the much heralded fall in the cost of abating so2 compared to original estimates can be attributed to allowance trading we demonstrate that for plants that use low sulfur coal to reduce so2 emissions technical change and the fall in prices of low sulfur coal have lowered marginal abatement cost curves by over 50 percent since 1985 the flexibility to take advantage of these chan

the role of market forces in assuring contractual performance the conditions under which transactors can use the market repeat purchase mechanism of contract enforcement are examined increased price is shown to be a means of assuring contractual performance a necessary and sufficient condition for performance is the existence of price sufficiently above salvageable production costs so that the nonperforming firm loses a discounted steam of rents on future sales which is greater than the wealth increase from nonperformance this will generally imply a market price greater than the perfectly competitive price and rationalize investments in firm specific assets advertising investments thereby become a positive indicator of likely performance

price and quality of industrial products some results of an empirical investigation this paper deals with two issues using danish data on western european goods a test is presented in order to determine whether the concept of quality should be considered unidimensional as in the classical literature or multidimensional as in the characteristics approach the second issue is the relationship between price and technical quality previous studies have shown this relationship to be positive but rather weak in this paper some doubt is thrown on the methodology of these studies a test of the relationship between price and quality is given using data on individual characteristics

price and network dynamics in the european carbon market this paper presents an analysis of the european emission trading system as a transaction network it is shown that given the lack of a centralized market place industrial actors had to resort to local connections and financial intermediaries to participate in the market this gave rise to a hierarchical structure in the transaction network to empirically relate networks statistics to market outcomes a pls pm modeling technique is introduced it is shown that the asymmetries in the network induced market inefficiencies e g increased bid ask spread albeit the efficiency of the market has improved from the beginning of phase ii the asymmetry persists imposing unnecessary additional costs on agents and reducing the effectiveness of the market as a mitigation instrument

the concept of quality and the efficiency of markets for consumer products can consumers trust prices to be good quality indicators previous studies based on quality data from consumer reports have indicated that the relation of price to overall quality is quite weak this paper demonstrates that these studies are methodologically invalid by showing that the concept of overall quality has many dimensions to what extent do inefficient variants occur in the market previous studies have suggested that there is a considerable degree of inefficiency in the market alternative calculations imply that inefficient variants are in fact frequent but that the loss to consumers is much lower than previously suggested

status inconsistency and product valuation in the california wine market this study develops a theoretical model on the role of multidimensional status and status inconsistency in market evaluation processes a product or an organization may acquire multiple status indicators in association with a multitude of market institutions we argue that when status indicators are consistently positive each exerts a greater positive effect on the valuation of a product or an organization conversely inconsistency among multiple indicators undermines the status claim we test this theoretical proposition by examining patterns of product valuation in the california premium wine market our findings show that when an individual wine s tasting score rated by critics and another more general status indicator classified appellation affiliation extra designation on the label or a winery s organizational status are consistently positive each makes a greater contribution to wine price in contrast when status indicators are inconsistent the value of the positive status indicator is reduced our study explicates the scope conditions under which market status may yield different outcomes and sheds light on the interplay among status indicators in market valuation

the role of international reserves holding in buffering external shocks an extended literature analyzes the accumulation foreign exchange holding observed in many developing and emerging countries since the 2000s empirical studies on the self insurance motive suggest that high reserves economies are more resilient to financial crises and to international capital inflows volatility they show also that pre crisis foreign reserve accumulation explains post crisis growth however some papers suggest that the relationship between international reserves holding and reduced vulnerability is nonlinear meaning that reserve holding is subject to diminishing returns this paper devotes more attention to the potential nonlinear relationship between the foreign reserves holding and macroeconomic resilience to shocks for a sample of 9 emerging economies we assess to what extent the accumulation of international reserves allows to mitigate negative impacts of external shocks on the output gap while a major part of the literature focuses on the global financial crisis we investigate this question by considering two sub periods 1995 2003 and 2004 2013 we implement threshold var tvar model in which the structure is allow to change if the threshold variable crosses a certain estimated threshold we find that the effectiveness of reserve holding to improve the resilience of domestic economies to shocks has increased over time hence the diminishing returns of foreign reserve holding stressed in the previous literature must be qualified

price trends and dynamic pricing in perishable product market consisting of superior and inferior firms abstract we consider the problem of a firm that sells perishable products with a dynamic pricing scheme in the presence of a firm offering a superior product we provide a probabilistic characterization of the optimal price process under the existence of such a firm for an aggregate demand model and for a multinomial logit demand model our results demonstrate that if the seller takes the price of the other firm into account in their optimal policy then the optimal price process tends to increase over time before the inventory level falls to one after which it decreases otherwise the price process decreases and then increases this path is called a j shaped curve before the inventory level falls to one if the price of the other firm is relatively low and the customer s valuation remains unchanged over time early in the sales period we also demonstrate numerically that when the firm uses a monopolistic policy and the difference in service quality between the two firms is large the switching time between the downward and upward trends takes place in the early stage of the sales period and in particular this j shaped phenomenon is strongly observed

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

signalling product quality when is price relevant abstract price has long been regarded as performing a dual role in the demand for products with unknown quality it represents the opportunity cost of the product and is one of several signals which indicate quality we argue that when quality signals are stochastic not all of them will be used in particular there will be a critical price above below which price is used not used to signal quality at this price an individual s demand curve will be characterised by a reverse kink this helps explain recent results from demand analysis including those reported by abbe decarroux in this journal

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

variable pricing in oligopoly markets behavioral research has found that consumers respond to variability in prices in addition to price levels we show that this finding can explain why some firms vary their prices more frequently than others we examine pricing strategies composed of an average price and price variability and employ logit market share models to analyze equilibrium pricing strategies in an oligopoly two competing logit specifications termed price sensitivity and payoff sensitivity are considered and are shown to yield contradictory implications for pricing policy from three empirical studies on restaurant choice we find that the price sensitivity model is the better model

foundations of dynamic monopoly and the coase conjecture subgame perfect equilibria are characterized for a market in which the seller quotes a price each period assume zero costs positive interest rate continuum of buyers and some technical conditions if buyers valuations are positive then equilibrium is unique buyers strategies are stationary and the price sequence is determinant along the equilibrium path but possibly randomized elsewhere otherwise a continuum of stationary equilibria can exist but at most one with analytic strategies coase s conjecture is verified for stationary strategies reducing the period length drives all prices to zero or the least valuation connections to bargaining models are described journal qf economic literature classification

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

monetary policy options for mitigating the impact of the global financial crisis on emerging market economies though the hypothesis that exchange rate regimes fully predetermine monetary policy in the face of external shocks hardly finds any advocates on theoretical ground it has crept in the most of empirical research this study adopts a more discerning empirical approach that looks at monetary policy tools used in order to accommodate the recent financial crisis we investigated the gdp growth in 45 emerging market economies in the most intense phase of the crisis and found out that there is no clear difference in the growth performance between countries at the opposite poles of the exchange rate regime spectrum depreciation cum international reserve depletion outperforms the other policy options especially the rise in the interest rate spread we discovered certain complementarities between the information on the policy option and on exchange rate regime taking into account non gaussian settings we decided to use quantile regression which provide in addition more complete picture of relationship between the covariates and the distribution of the gdp growth

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

does inequality lead to credit growth testing the rajan hypothesis using state level data this paper uses state level data to test the rajan hypothesis from his book fault lines that an increase in inequality can lead to a credit boom using dynamic heterogeneous panel estimation methods i e mg pmg dfe we find a significant positive long run relationship between inequality and real estate lending across u s states

dynamic pricing in the presence of strategic consumers and oligopolistic competition we present a dynamic pricing model for oligopolistic firms selling differentiated perishable goods to multiple finite segments of strategic consumers who are aware that pricing is dynamic and may time their purchases accordingly this model encompasses strategic behavior by both firms and consumers in a unified stochastic dynamic game in which each firm s objective is to maximize its total expected revenues and each consumer responds according to a shopping intensity allocation consumer choice model we prove the existence of a unique subgame perfect equilibrium provide equilibrium optimality conditions and prove monotonicity results for special cases the model provides insights about equilibrium price dynamics under different levels of competition asymmetry between firms and multiple market segments with varying properties we demonstrate that strategic behavior by consumers can have serious impacts on revenues if firms ignore that behavior in their dynamic pricing policies moreover ideal equilibrium responses to consumer strategic behavior can recover only a portion of the lost revenues a key conclusion is that firms may benefit more from limiting the information available to consumers than from allowing full information and responding to the resulting strategic behavior in an optimal fashion

macroeconomic adjustment and the history of crises in open economies abstract this paper investigates the impact of the history of crises on macroeconomic performance we first study the impact of past banking crises on the probability of a future banking crisis we do not detect a learning process from past banking crises countries that have already experienced one banking crisis generally have a higher likelihood of experiencing another crisis and the depth of the crisis does not appear to be affected by the previous historical experience with crisis events evidence also suggests that in middle income countries higher de jure capital account openness is associated with lower likelihood of a banking crisis a lower ratio of non performing loans during the crisis and higher levels of forgone output in the crisis aftermath in contrast we find that past crisis experience has a significant impact on savings when facing considerable political risk the past does seem to matter countries with more people who were exposed over their lifetime to larger disasters will tend to save more this association however does not hold for countries with more stable political systems

bank credit risk grain production and the indian economy we generate measures of banking risk across indian states and examine the relationship between banking risk and economic production in india we find that banking risk co moves with total grain pro

micro level transmission of monetary policy shocks the trading book channel abstract we open the black box of the monetary policy transmission mechanism with a granular model that considers the balance sheet composition and network relationships of each economic agent though there are several well documented channels through which monetary policy operates we focus on the overlooked trading book channel which arises because of adjustments in the accounting value of trading book exposures on banks balance sheets that have to be marked to market when interest rates change variations in banks net worth due these adjustments are used as input to a network model that incorporates the financial and corporate sectors the framework permits us to determine the effects of interest rate changes on every bank and firm in the economy and any second round contagion effects in the short run we apply the model to a comprehensive database of brazilian banks and firms from 2015 to 2020 we find that interest rate shocks affect more strongly financial stability in periods of monetary policy tightening we also find notable asymmetric effects of positive and negative interest rate shocks in the brazilian economy with positive interest rate shocks affecting more financial stability finally our results also suggest a non linear relationship between interest rate changes and financial stability reinforcing the need to mitigate monetary policy shocks through interest rate smoothing and adequate communication and transparency to society

quality indicators in theory and in fact abstract in recent literature it has been suggested that consumers need have no knowledge of product quality as a number of quality indicators or signals may be used as substitutes very little attention has been paid to the empirical verification of these studies the present paper is devoted to the issue of how well these indicators perform using market data provided by consumer magazines from 3 countries the results strongly indicate that price is a poor quality indicator the paper also presents some evidence which suggests that seller reputation and easily observable characteristics are also poor indicators

dynamic pricing when consumers are strategic analysis of posted and contingent pricing schemes abstract we study dynamic pricing policies for a monopolist selling perishable products over a finite time horizon to strategic buyers buyers are strategic in the sense that they anticipate the firm s price policies it is expensive and administratively difficult for most brick and mortar retailers to change prices placing limits on the number of price changes and the types of pricing policies they can adopt the simplest policy is to commit to a set of price changes a more complex alternative is to let the price depend on sales history we investigate two pricing schemes that we call posted and contingent pricing using the posted pricing scheme the firm announces a set of prices at the beginning of the horizon in the contingent pricing scheme price evolution depends upon demand realization our focus is on the posted pricing scheme because of its ease of implementation counter to intuition we find that neither a posted pricing scheme nor a contingent pricing scheme is dominant and the difference in expected revenues of these two schemes is small limiting the number of price changes will result in a decrease in expected revenues we show that a multi unit auction with a reservation price provides an upper bound for expected revenues for both pricing schemes numerical examples suggest that a posted pricing scheme with two or three price changes is enough to achieve revenues that are close to the upper bound dynamic pricing is only useful when strategic buyers perceive scarcity we study the impact of scarcity and derive the optimal stocking levels for large markets finally we investigate whether or not it is optimal for the seller to conceal inventory or sales information from buyers a firm benefits if it does not reveal the number of units it has available for sale at the beginning of the season or subsequently withholds information about the number of units sold

lancaster s principle of efficient choice an empirical note abstract lancaster s principle of efficient choice is submitted to an empirical examination using data from consumer reports the results give only moderate support for that principle

the growth of multinational firms in the great recession abstract using a large firm level dataset this paper studies multinational firms performance during the great recession foreign multinationals grew faster than local firms outside of the crisis but slower during the crisis industry and size differences between domestic and foreign owned firms account for much of this slowdown however multinationals from different countries performed differently during the crisis the paper then assesses the role of multinationals in the global recession using a quantitative model had multinationals relative performance remained unchanged during the crisis the median country s aggregate growth would have been 0 12 higher with a range of 0 13 to 0 5 across countries

stock market structure and volatility the procedure for opening stocks on the nyse appears to affect price volatility an analytical framework for assessing the magnitude of the structurally induced volatility is presented the ratio of variance of open to open returns to closeto close returns is shown to be consistently greater than one for nyse common stocks during the period 1982 through 1986 tbe greater volatility at the open is not attributable to the way in which public information is released since both the opento open return and the close to close return span the same period of time instead the greater volatility appears to be attributable to private information revealed in trading and to temporaryprice deviations induced by specialist and other traders the implied cost of immediacy at the open is significantly higher than at the close other empirical evidence in this article documents the volume of trading at the open the time delays between the exchange opening and the first transaction in a stock the difference in daytime volatility versus overnight volatility and the extent to which volatility is related to trading volume

risk and global economic architecture why full financial integration may be undesirable integration of global financial markets was supposed to lead to greater financial stability as risks were spread around the world the finan cial crisis has thrown doubt on this conclusion a failure in one part of the global economic system caused a global meltdown the recent crisis has shown that in the absence of appro priate government intervention privately profit able transactions may lead to systemic risk this paper provides a general analytic framework within which we can analyze the optimal degree and form of financial integration within this general framework full integration is not in general optimal indeed faced with a choice between two polar regimes full integration or autarky in the simplified model autarky may be superior

an empirical analysis of latitude of price acceptance in consumer package goods scanner panel data analyses for sweetened and unsweetened drink categories with four brands in each support the presence of a region of price insensitivity around a reference price the analyses also suggest that consumers with higher average reference price have a wider latitude of price acceptance consumers with a higher frequency of purchase i e shorter average interpurchase time interval are found to have a narrower latitude of price acceptance because they are more aware of the range of price distributions finally consumers with a higher average brand loyalty have a wider latitude of price acceptance demonstrating greater tolerance of price fluctuations

prices as signals of product quality this paper is concerned with the provision of quality in markets in which consumers have only imperfect information the analysis focuses on a market for a product that can be produced at different quality levels all consumers prefer higher to lower quality but they may differ in their willingness to pay for quality producers can produce any quality they like but higher qualities are more costly to produce the information in this market is imperfect in the sense that the exact quality chosen by a firm is known only to the firm itself some information about the quality of a firm s product will however reach its potential customers even if they do not make any special effort to acquire it within the framework suggested here two conclusions are drawn first prices may serve as signals which exactly differentiate the available quality levels that is there exists a fulfilledexpectations equilibrium at which each price signals a unique quality level second the pricesignals are not arbitrary each price signal exceeds the marginal cost of producing the quality it signals such a mark up depends on the nature of the product specific information received by consumers the poorer the information the higher the mark up

a range theory account of price perception it is well accepted in the behavioral pricing literature that a consumer s perception of the attractiveness of a market price depends on a comparison of the market price to an internal reference price the rationale underlying this dynamic has its roots in adaptation level theory however consistent with range theory we postulate that a consumer s assessment of the attractiveness of a market price may also depend on a comparison of the market price to the endpoints of the evoked price range four experiments provide evidence that variance in the width of the evoked price range affects price attractiveness judgments in the absence of any variance in the internal reference price of theoretical importance findings from the present article suggest that pricing theory is in need of augmentation in order to account for this effect of managerial relevance these findings suggest that changes in context can bring about changes in the evoked price range and perceptions of the attractiveness of a market price

credit cycle coherence in the eurozone was there a euro effect this paper examines effects of the euro introduction on credit cycle coherence in the eurozone through six channels we construct and describe credit cycles for total bank credit household mortgages and non financial business loans for 16 emu economies over 1990 2015 credit cycle coherence is measured by synchronicity of cycle movements and similarity of their amplitudes we find that the effect of euro introduction runs through elimination of currency risk and higher capital flows which decrease coherence of total credit and mortgage credit cycles but increase coherence of business credit cycles falling interest rates contribute to the convergence of total and mortgage credit cycles financial deregulation and legal harmonization are associated with lower coherence of all credit cycles while trade openness has the opposite impact the findings impinge on monetary policy effectiveness in the eurozone with implications for macroprudential policy

standard deviations implied in option prices as predictors of future stock price variability abstract standard deviations implied in option prices have recently been introduced as being better than average predictors of future stock price variability this article specifically studies the predictive ability of implicit standard deviations taking into account the dividend problem and the problem of optimal weighting schemes of the standard deviations when there are several options on the same stock transaction data information was used to study the importance of non simultaneities in observing stock and option prices

option prices implied price processes and stochastic volatility this paper characterizes all continuous price processes that are consistent with current option prices this extends derman and kani 1994 dupire 1994 1997 and rubinstein 1994 who only consider processes with deterministic volatility our characterization implies a volatility forecast that does not require a specific model only current option prices we show how arbitrary volatility processes can be adjusted to fit current option prices exactly just as interest rate processes can be adjusted to fit bond prices exactly the procedure works with many volatility models is fast to calibrate and can price exotic options efficiently using familiar lattice techniques

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

product quality and imperfect information this paper considers markets in which consumers are imperfectly informed about both product prices and quality levels offered by firms we characterize necessary and sufficient conditions for existence of the various equilibrium configurations of price and quality that can arise in two paradigm cases when all consumers prefer higher quality and when all consumers prefer lower quality our results suggest that firms will exploit imperfect information by charging noncompetitive prices as well as by offering other than ideal quality in the former case but only by changing noncompetitive prices in the latter case

liaisons dangereuses increasing connectivity risk sharing and systemic risk the recent financial crisis poses the challenge to understand how systemic risk arises endogenously and what architecture can make the financial system more resilient to global crises this paper shows that a financial network can be most resilient for intermediate levels of risk diversification and not when this is maximal as generally thought so far this finding holds in the presence of the financial accelerator i e when negative variations in the financial robustness of an agent tend to persist in time because they have adverse effects on the agent s subsequent performance through the reaction of the agent s counterparties 2012 elsevier b v all rights reserved

competitive promotional strategies this article analyzes the equilibrium pricing strategies of brands engaged in a pricing game each brand has a monopoly market loyal consumers and competes with others in a common market called brand switchers in the case of a duopoly it is shown that the behavior of the brand switchers characterizes the equilibrium behavior of the duopolists this article focuses on two key comparative statics namely the depth of discounts away from a regular high price and the probability of giving a deal or the frequency of deals how these properties vary with the size of the loyal markets and the behavior of the brand switching population is discussed copyright 1988 by the university of chicago

do capital flows change domestic credit allocation since the 1990s domestic bank credit has been reallocated away from lending to non financial business and toward households an expanding literature discusses negative effects on growth and stability of this change in credit allocation we research its drivers we hypothesize that if foreign capital flows into economies with few investment opportunities it may substitute for domestic bank lending to non financial business so that bank balance sheets become more dominated by household lending in gmm estimations on data for 36 economies over 1990 2011 we find evidence consistent with this mechanism foreign capital inflows into the non bank sector but not into the bank sector are associated with lower shares of business lending in domestic bank portfolios the association is weaker in economies with more investment opportunities whether proxied by investment shares current account surpluses or emu membership our results highlight the importance of sectoral destination in determining the effects of capital flows

indexing product quality issues theory and results jn the concept of quality and the efficiency of markets for consumer products hjorth andersen 1984 strongly condemns the use of overall productquality rankings such as those published by consumer reports as a basis for scientific research his primary criticism is that creating an index of quality as a weighted average of subscores is usually misleading he claims that this averaging process is unjustified except for brands that occupy approximately the same rank position on each attribute this article reviews hjorth andersen s arguments and identifies several important related questions on the use of published quality ratings in academic research statistical theory is developed to demonstrate that hjorth andersen s conclusions are limited and to examine the precise conditions under which his conclusions hold empirical evidence is presented that reveals the statistical frequency in real markets of the logical conditions deduced using our theory our conclusions differ significantly from those drawn by hjorthandersen a debate about the efficacy of quality indices is relevant not only to academic research but also to consumer welfare and strategic marketing planning consumer welfare and choice is affected by published quality ratings archibald haulman and moody 1983 beales et al 1981 thorelli and thorelli 1977 commercial importance is evident from the widespread distribution of magazines like consumer reports the consumer testing movement started in 1927 by chase and schlink has spread to agencies in more than 50 nations these agencies are members of the international organization of consumers unions iocu and the combined circulation of their magazines is in the millions published quality ratings also influence academic research our literature review identified more than 30 studies that use objective quality ratings as data from which to draw inferences about price versus quality tradeoffs advertising versus quality interactions price versus quality changes over product life cycles brand switching market efficiency and rational consumer judgments since this review concentrated on the marketing and economics literature it is likely that the role of published quality ratings in academic research has been underestimated in any case academic researchers can and should assist product testing agencies in understanding sources of potential error in their quality scales strategic research such as that conducted by the strategic planning institute at harvard university has focused management attention on the influence of product quality on market performance measures like market share and rate of return on investment for example phillips chang and buzzell 1983 indicate that product quality influences a firm s market share directly and its rate of return on investment indirectly through market share see also day 1986 farris and reibstein 1979 urban et al 1984 it is important that future research define coherently and measure accurately the construct of quality

the evolution of free trade networks abstract this paper considers the evolutionary dynamics of a free trade agreement fta network formation game among n countries we first explore the static model introduced by goyal and joshi 2006 and precisely characterize the set of pairwise stable fta networks then we develop a dynamic model under random perturbations and identify long run outcomes to remove prediction uncertainty inherited from static analysis the results show that both partial free trade and global free trade will result when there are only three countries however when more countries are involved only the complete fta network emerges

looking for a needle in a haystack revisiting the cross country causes of the 2008 9 crisis by bayesian model averaging in this paper we explore the cross country variation in the output impact of the global financial crisis in 2008 9 we use the extensive dataset of rose and spiegel but control for the problems of model uncertainty and outliers by using a variety of bayesian model averaging techniques we find first that cross country differences in crisis intensity can be explained by macroeconomic vulnerabilities second ignoring model uncertainty can lead to incorrect inferences third international trade linkages do matter

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

revenue management for low cost providers low cost providers have emerged as important players in many service industries the most predominant being low cost or the so called discount airlines this paper presents models and results leading toward understanding the revenue management outlook for a discount pricing firm a framework and model is formulated specifically for the airline industry but is generalizable to low cost providers in similar revenue management settings we formulate an optimal pricing control model for a firm that must underprice to capture a segment of exogenous demand two specific model formulations are considered a continuous deterministic version and a discrete stochastic version structural results are derived for the deterministic case providing insight into the general form of optimal underpricing policies the stochastic results support the structural insight from the deterministic solution and illuminate the effect of randomness on the underpricing policies

price and advertising signals of product quality we present a signaling model based on ideas of phillip nelson in which both the introductory price and the level of directly uninformative advertising or other dissipative marketing expenditures are choice variables and may be used as signals for the initially unobservable quality of a newly introduced experience good repeat purchases play a crucial role in our model a second focus of the paper is on illustrating an approach to refining the set of equilibria in signalling games with multiple potential signals

prices product qualities and asymmetric information the competitive case recent developments in the economics of information emphasize the informational content of prices we examine the degree to which prices convey information on product quality to uninformed agents under perfect competition we show that a rational expectations equilibrium may not exist when an equilibrium does exist the information on quality conveyed by prices depends on the shape of the average cost curves and the relative numbers of informed and uniformed agents

product warranties and double moral hazard this article explores a model of warranties in which moral hazard problems play a key role the goal is to understand the important characteristics of warranties including their provision of incomplete insurance and the relationship between product quality and coverage we analyze a model in which buyers and sellers take actions that affect a product s performance since these actions are not cooperatively determined an incentives problem arises we characterize the optimal warranty contract and undertake comparative statics to determine the predicted correlation of warranty coverage and product quality

is full banking integration desirable abstract we analyze the links between banking integration and economic development for a sample of oecd countries we measure banking integration considering indicators that merge not only openness but also connectedness with other banking systems we plug these indicators into income regressions also controlling for other relevant variables considered by the literature in contrast to previous initiatives this second stage explicitly takes into account the differing levels of economic development of the countries in our sample since the benefits of enhanced banking integration might not be generalizable to this end we implement quantile regression also considering the presence of endogenous regressors results show that bank connectedness is more important for economic development than bank openness but the combined effect i e banking integration overall is positive and significant the quantile regression models used in the second stage show that the effects are stronger for the poorest economies

foreign direct investment and external financing conditions evidence from normal and crisis times this paper investigates the effects that external financing conditions in source and destination countries have on foreign direct investment fdi in normal and crisis times using a difference in differences approach we find that source and destination countries financial development have a strong positive impact on the relative volume of fdi in financially vulnerable sectors in normal times on the other hand during the 2008 2010 global financial crisis the relative volume of fdi in financially vulnerable sectors fell relatively more in financially developed source and destination countries most notably if these countries experienced a credit crisis

estimation of a hedonic price equation for burgundy wine a hedonic price equation and two jury grade equations are estimated for burgundy wine the approach is the same as in an earlier bordeaux wine paper combris et al 1997 the data come from an experimental study that is very similar to the study on bordeaux wines the results for the two wine growing regions are compared and discussed

optimal price skimming by a monopolist facing rational consumers this paper considers the intertemporal pricing problem for a monopolist marketing a new product the key feature differentiating this paper from the extant management science literature on intertemporal pricing is the assumption that consumers are intertemporal utility maximizers a subgame perfect nash equilibrium pricing policy is characterized and shown to involve intertemporal price discrimination we compare this policy to the optimal policy for a monopolist facing myopic consumers and find that for any given state prices are always lower with rational consumers than with myopic consumers for plausible parameter values the assumption of consumer rationality can be shown to lead to large differences in optimal prices moreover if a monopolist facing rational consumers implements the optimal myopic consumer pricing policy profits can be significantly less than if the monopolist follows the equilibrium pricing policy for rational consumers

financial networks contagion commitment and private sector bailouts i develop a model of financial networks in which linkages not only spread contagion but also induce private sector bailouts where liquid banks bail out illiquid banks because of the threat of contagion introducing this bailout possibility i show that linkages may be optimal ex ante because they allow banks to obtain some mutual insurance even though formal commitments are impossible however in some cases e g when liquidity is concentrated among a small group of banks the whole network may collapse i also characterize the optimal network size and apply the results to joint liability arrangements and payment systems linkages among agents in financial markets are a concern because of the risk of financial contagion that is the risk that a small shock to one agent will spread to other agents in a domino effect whether we should worry about these linkages is an open question the main goal of this paper is to show that a network in which agents are closely interlinked may be optimal both because of and despite the potential for contagion another goal is to characterize optimal networks that is whether and how agents should be linked to one another the basic intuition is as follows linkages present the threat of contagion to prevent collapse of the whole network agents who are lucky ex post may be willing to bail out those who are not in this way agents obtain the benefits of mutual insurance even though they cannot precommit to making payments

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

financial contagion on the international trade network we combine data on international trade linkages with a network approach to map the global trading system as an interdependent complex network this enables us to obtain indicators of how well connected a country is into the global trading system we use these network based measures of connectedness to explain stock market returns during recent episodes of financial crisis we find that a crisis is amplified if the epicenter country is better integrated into the trade network however target countries affected by such a shock are in turn better able to dissipate the impact if they are well integrated into the network a network approach can help explain why the mexican asian and russian financial crises were highly contagious while the crises that originated in venezuela and argentina did not have such a virulent effect we suggest that a network approach incorporating the cascading and diffusion of interdependent ripples when a shock hits a specific part of the global trade network provides us with an improved explanation of financial contagion jel f10 f36 f40 g15

the great recession us dynamics and spillovers to the world economy abstract this paper provides an empirical investigation of both the within us and international channels of transmission of macroeconomic and financial shocks by means of a 50 country macroeconometric model estimated over the 1980 2009 period including measures of excess liquidity and financial fragility specifically designed in order to evaluate the relevance of the boom bust credit cycle view put forward as an interpretation of the recent great recession episode we find that such a view is consistent with the empirical evidence moreover concerning the real effects of financial shocks within the us we detect stronger evidence of an asset prices channel rather than a liquidity channel concerning the spillovers to the world economy we find that while financial disturbances are transmitted to foreign countries through us house and stock price dynamics as well as excess liquidity creation the trade channel is the key trasmission mechanism of real shocks

information remedies for consumer protection consumer protection regulation has come under increasing fire from the congress courts and the business community in response regulators have begun to innovate with market interventions that are more compatible with economic incentives these incentive compatible techniques include establishing property rights mandating performance standards instead of design standards increasing competition and encouraging and mandating information disclosure information disclosure allows consumer self protection compatible with individual preferences information is also compatible with sellers incentives inducing them to compete on the basis of information disclosed in addition this competition increases the incentive to generate and disseminate additional product information thereby repeating the cycle in this way information remedies rely on private economic incentives to achieve regulatory goals rather than on expensive direct enforcement by the regulator diagnosis of an information problem and evaluation of alternative remedies requires a number of steps analysis of information production and distribution identification of market failures and their implications for resource allocation in the information and product markets and analysis of alternative remedies in light of these market failures

quality uncertainty and price in monopoly markets this paper examines a monopoly firm s pricing strategy in a market in which consumers have varying and imprecise estimates of the quality of the firm s product it is shown that the firm s price declines in response to an increase in the level of consumer uncertainty about quality when consumer tastes for the product are sufficiently similar and their uncertainty about quality is sufficiently small when one or both of these conditions fails to hold however it is shown that the monopoly firm s price is positively related to the level of consumer uncertainty about quality copyright 1996 by blackwell publishing ltd

purchasing pricing and quick response in the presence of strategic consumers we consider a retailer that sells a product with uncertain demand over a finite selling season the retailer sets an initial stocking quantity and at some predetermined point in the season optimally marks down remaining inventory we modify this classic setting by introducing three types of consumers myopic consumers who always purchase at the initial full price bargain hunting consumers who purchase only if the discounted price is sufficiently low and strategic consumers who strategically choose when to make their purchase a strategic consumer chooses between a purchase at the initial full price and a later purchase at an uncertain markdown price in equilibrium strategic consumers and the retailer make optimal decisions given their rational expectations regarding future prices availability of inventory and the behavior of other consumers we find that the retailer stocks less takes smaller price discounts and earns lower profit if strategic consumers are present than if there are no strategic consumers we find that a retailer should generally avoid committing to a price path over the season assuming such commitment is feasible committing to a markdown price or to not mark down at all is often too costly inventory may remain unsold even in the presence of strategic consumers the better approach is to be cautious with the initial quantity and then mark down optimally furthermore we discuss the value of quick response the ability to procure additional inventory after obtaining updated demand information albeit at a higher unit cost than the initial order we find that the value of quick response to a retailer is generally much greater in the presence of strategic consumers than without them on average 67 more valuable and as much as 558 more valuable in our sample in other words although it is well established in the literature that quick response provides value by allowing better matching of supply with demand it provides more value often substantially more value by allowing a retailer to control the negative consequences of strategic consumer behavior
