exchange rate crises and fiscal solvency this paper combines insights from generation one currency crisis models and the fiscal theory of the price level ftpl to create a dynamic ftpl model of currency crises the initial fixed exchange rate policy entails risks due to an upper bound on government debt and stochastic surplus shocks agents refuse to lend into a position for which the value of debt exceeds the present value of expected future surpluses policy switching usually combined with currency depreciation restores fiscal solvency and lending this model can explain a wide variety of crises including those involving sovereign default we illustrate by explaining the crisis in argentina 2001

behind the scenes of abandoning a fixed exchange rate regime abstract this paper explores the process of abandoning a fixed exchange rate regime during sudden stops in a small open economy the bank of korea s exchange rate policy reports during the east asian crisis suggest that its fixed exchange rate regime was forced to collapse due to the depletion of usable foreign reserves which resulted from the credit policy of the korean central bank to support domestic banks in need of foreign currency liquidity to capture the korean crisis experience i build a quantitative small open economy model in which in response to the country risk premium shock the foreign currency credit policy of a central bank under fixed regime leads to the exhaustion of international reserves and consequent exchange rate regime shift this model does well at replicating the observed contraction in korean aggregate variables

balance of payments crises in a cash in advance economy the author shows that a flexible prices sidrauski type model with a cash in advance constraint is capable of depicting some of the phenomena associated with a balance of payments crisis like the onesrecently observed in argentina and mexico current accounts deficits and appreciation of the real exchange rat e it is also shown that these phenomena become exacerbated as the rate of devaluation before the crisis occurs becomes smaller copyright 1987 by ohio state university press

profit margins and the business cycle evidence from uk manufacturing firms this paper presents some empirical models of profitability using panel data covering 709 large u k companies ove r the 1970s and 1980s focusing specifically on the role of aggregate demand shocks in shaping firm level profitability in basic regressi ons and in quite complex econometric models the results suggest that firm level profit margins fell heavily during the deep manufacturing recession of the early 1980s and as such are consistent with model s predicting the procyclical nature of profit margins this result hol ds across different product groups producer goods consumer durables a nd nondurables though the timing of the impact of aggregate shocks appears to differ copyright 1993 by blackwell publishing ltd

speculation and the decision to abandon a fixed exchange rate regime this paper investigates the extent to which it is possible for speculative attacks to be predictable given information on economic fundamentals a standard model of predictable attacks is extended to incorporate an optimizing monetary authority it is shown that while incorporating a forward looking monetary authority improves our understanding of many observed phenomena it also implies that the branch of the literature that places emphasis on predictable movements in fundamentals cannot generate predictable speculative attacks in addition the model provides useful insights into the viability of temporary nominal anchor policies and a theoretical foundation for an important empirical methodology

nash equilibrium with mark up pricing oligopolists abstract if business managers formulate strategies in terms of mark ups then it is natural to think they will think of their rivals actions in these terms for a market characterized by constant elasticity of demand and supply the mark up equilibrium is derived and compared with the traditional monopoly cournot and perfectly competitive equilibria we also compute the revenue as strategy equilibria

behavior of output during currency crises abstract this paper documents the behavior of output and its association with other macroeconomic variables in 195 episodes of currency crises in developing countries during 1970 2000 we find that about 60 of the crises are contractionary while the rest are expansionary crises are one and a half times more likely to be contractionary in emerging markets than in other developing economies the number of contractionary crises or their severity does not increase in the 1990s economies which experience capital inflows in the years prior to the crisis or an increase in external debt burden during the crisis are more likely to slow down during crises while those with restrictions on capital flows prior to the crisis or are more open to international trade are less likely to do so the results are robust to different ways of measuring changes in output during crises

delaying the inevitable interest rate defense and balance of payments crises the classical model of balance of payments crises implicitly assumes that the central bank sits passively as international reserves dwindle in practice however central banks typically defend pegs aggressively by raising short term interest rates this paper analyzes the feasibility and optimality of raising interest rates to delay a potential bop crisis interest rate policy works through two distinct channels by raising demand for domestic interest bearing liquid assets higher interest rates tend to delay the crisis higher interest rates however increase public debt service and imply higher future inflation which tends to bring forward the crisis we show that under certain conditions it is feasible to delay the crisis but raising interest rates beyond a certain point may actually hasten the crisis a similar nonmonotonic relationship emerges between welfare and the increase in interest rates it is thus optimal to engage in some active interest rate defense but only up to a certain point i

collapsing exchange rate regimes another linear example abstract in the literature on speculative attacks on a fixed exchange rate it is usually assumed that the monetary authority responsible for fixing the rate reacts passively to the monetary disruption caused by the attack this assumption is grossly at odds with actual experience where the monetary base implications of the attacks are usually sterilized such sterilization means that the attack is no longer exclusively a monetary event and requires that the standard attack model be broadened to include the effects of sterilization on other markets these issues are motivated by reference to the december 1994 collapse of the mexican peso

on the optimality of interest rate smoothing abstract this paper studies some continuous time cash in advance models in which interest rate smoothing is optimal we consider both deterministic and stochastic models in the stochastic case we obtain two results of independent interest i we study what is to our knowledge the only version of the neoclassical model under uncertainty that can be solved in closed form in continuous time and ii we show how to characterize the competitive equilibrium of a stochastic continuous time model that cannot be computed by solving a planning problem we also discuss the scope for monetary policy to improve welfare in an economy with a suboptimal real competitive equilibrium focusing on the particular example of an economy with externalities

collusion with capacity constraints over the business cycle this paper investigates the efiect of capacity constraints on the sustainability of collusion in markets subject to cyclical demand uctuations in the absence of capacity constraints i e a limiting case of our model haltiwanger and harrington 1991 show that flrms flnd it more di cult to collude during periods of decreasing demand we flnd that this prediction can be overturned if flrms capacities are su ciently small capacity constraints imply that punishment proflts move procyclically so that periods of increasing demand may lead to lower losses from cheating even if collusive proflts are rising haltiwanger and harrington s main prediction remains valid for su ciently large capacities

optimal fiscal and monetary policy in an economy without capital abstract this paper is concerned with the structure and time consistency of optimal fiscal and monetary policy in an economy without capital in a dynamic context optimal taxation means distributing tax distortions over time in a welfare maximizing way for a barter economy our main finding is that with debt commitments of sufficiently rich maturity structure an optimal policy if one exists is time consistent in a monetary economy the idea of optimal taxation must be broadened to include an inflation tax and we find that time consistency does not carry over an optimal inflation tax requires commitment by rules in a sense that has no counterpart in the dynamic theory of ordinary excise taxes the reason time consistency fails in a monetary economy is that nominal assets should from a welfare maximizing point of view always be taxed away via an immediate inflation in a kind of capital levy this emerges as a new possibility when money is introduced into an economy without capital

when is it optimal to abandon a fixed exchange rate the influential krugman flood garber kfg model of balance of payment crises assumes that a fixed exchange rate is abandoned if and only if international reserves reach a critical threshold value from a positive standpoint the kfg rule is at odds with many episodes in which the central bank has plenty of international reserves at the time of abandonment we study the optimal exit policy and show that from a normative standpoint the kfg rule is generally suboptimal we consider a model in which the fixed exchange rate regime has become unsustainable due to an unexpected increase in government spending we show that when there are no exit costs it is optimal to abandon immediately when there are exit costs the optimal abandonment time is a decreasing function of the size of the fiscal shock for large fiscal shocks immediate abandonment is optimal our model is consistent with evidence suggesting that many countries exit fixed exchange rate regimes with still plenty of international reserves in the central bank s vault copyright 2008 wiley blackwell

disinflation and fiscal reform a neoclassical perspective abstract many latin american countries engaged in disinflation programs based on both exchange rate management and fiscal reforms in most of the cases part of the fiscal reform was not implemented and the program had to be abandoned the aftermath of these programs is not encouraging in this paper we show that if the reform process is uncertain and inflation has welfare costs the optimal exchange rate policy indeed implies the initiation of a disinflation program at the announcement of the fiscal reform even if it implies the possibility of a balance of payments crisis finally we show that it is optimal to engage in a sequence of stabilization programs until one of them is successful

multimarket contact and collusive behavior traditional analyses of industrial behavior typically link the exercise of market power in an industry to internalfeatures such as demand conditions concentration and barriers to entry nevertheless some economists have remained concerned that external factors such as contact across markets may also play a significant role in determining the level of competitiveness in any particular industry in this article we examine the effect of multimarket contact on the degree of cooperation that firms can sustain in settings of repeated competition we isolate conditions under which multimarket contact facilitates collusion and show that these collusive gains are achieved through modes of behavior that have been identified in previous empirical studies of multimarketfirms

food security policy in a stochastic world abstract food security may be increased by variance reducing strategies by food aid or by development strategies this paper uses a korea cge model subjected to random fluctuation in world prices and domestic food productivity to evaluate these policies we find that poverty reducing development strategies are the most food security strategies

political economy of rice price protection in asia rice continues to be the most important food staple in asia contributing 40 80 of total calorie intake rice is also the major source of livelihood of small farmers and agricultural labor households in this region where at least two thirds of arable land is planted to rice at least half of that rice area is rain fed and vulnerable to drought and floods even in irrigated areas higher cropping intensity has increased pest problems contributing further to the production instability that characterizes the rice economy of monsoon asia because of the economic and political importance of rice in asia no government has left its domestic rice sector freely influenced by market demand and supply forces invariably the central food policy question confronting asian governments is how to reconcile the conflicting objectives of providing low rice prices to consumers and remunerative incentives to farmers maintaining stable domestic rice prices to both consumers and producers is a separate and equally important concern moreover given the political importance of rice and the instability of the world rice market most asian countries aim for rice selfsufficiency rather than rely on international trade to pursue their food security goals among rice exporters on the other hand raising government revenues from rice exports is another policy objective to achieve the above objectives a wide variety of policy instruments have been used to influence output and input prices directly or to increase productivity except for thailand most asian governments control rice prices in the short run through a monopoly on international trade as well as by engaging in domestic marketing operations 1 on the other hand governments also invest in irrigation

output costs currency crises and interest rate defence of a peg central banks typically raise short term interest rates to defend currency pegs higher interest rates however often lead to a credit crunch and an output contraction we model this trade off in an optimising first generation model in which the crisis may be delayed but is ultimately inevitable we show that higher interest rates may delay the crisis but raising interest rates beyond a certain point may actually bring forward the crisis due to the large negative output effect the optimal interest rate defence involves setting high interest rates relative to the no defence case both before and at the moment of the crisis

optimal cartel equilibria with imperfect monitoring abstract there exist optimal symmetric equilibria in the green porter model 4 8 having an elementary intertemporal structure such an equilibrium is described entirely by two subsets of price space and two quantities the only production levels used by firms in any contingency the central technique employed in the analysis is the reduction of the repeated game to a family of static games

speculative attack and the external constraint in a maximizing model of the balance of payments balance of payments models of speculative attack differ from non renewable resource models in that foreign exchange reserves may be borrowed from abroad this paper shows that in an idealized world where all private income is subject to lump sum taxation central bank reserves can become infinitely negative without violating the government s intertemporal budget constraint none the less a growth rate of domestic credit exceeding the world interest rate if maintained indefinitely leads to violation of the constraint in the paper s model given an assumed limit to official external borrowing the paper next analyses inevitable transitions between fixed and floating exchange rate regimes when individual preferences are explicitly specified in a discrete time deterministic model the collapse of a fixed rate may be characterized by two successive speculative attacks

rice prices and income distribution in thailand a non parametric analysis rice is a staple crop in thailand significantly entering both household production and consumption this paper examines the effect of rice prices on the distribution of real income across households taking into account household characteristics and geographical location the data set is a large scale survey of 11 893 households simple nonparametric techniques for regression and density estimation are used these methods depend on few assumptions and generate flexible graphical results that are directly informative about the problem at hand the main results are that higher rice prices should benefit all rural households but the largest benefits accrue to rural households in the middle of the income distribution copyright 1989 by royal economic society

rational and self fulfilling balance of payments crises speculative attacks on a pegged exchange rate must sometimes occur ifasset price paths are to be free of abnormal profit opportunities suchattacks are fully rational as they reflect the market s response to aregime breakdown that is inevitable the authors shows that under someexpectations about policy balance of payments crises can also be purely self fulfilling events in such cases even a permanently viableregime may collapse and the economy will possess multiple equilibriacorresponding to different subjective assessments of the probability ofa crisis the behavior of the domestic interest rate will naturally reflect the possibility of a speculative attack copyright 1986 by american economic association

an interest rate defense of a fixed exchange rate defending a government s exchange rate commitment with active interest rate policy is not an option in first generation models of speculative attacks in those models the interest rate is the passive reflection of currency depreciation expectations in this paper we show how to adapt the first generation framework to allow for an interest rate defense it is shown that increasing domestic currency interest rate before the attack makes domestic assets more attractive according to an asset substitution effect but weakens the domestic currency by increasing the government s fiscal liabilities as a result an interest rate defense can be successful only conditional on sound fiscal policy

economic costs of alternative monetary policy responses to speculative currency attacks abstract the outcome of a speculative attack on the foreign exchange rate can be classified into three cases i immediate depreciation of the nominal exchange rate ii successful defense or iii failed defense this paper explores which of these outcomes yields the lowest cost in terms of output and unemployment in the short and medium run ex ante the outcome of a speculative attack is uncertain therefore the appropriate response of monetary authorities to a speculative attack depends on the cost of an immediate depreciation compared with that of the expected outcome of a currency defense our empirical analysis focuses on a sample of 73 emerging and developing countries over the 1960 2011 period our results indicate that an immediate depreciation is the policy response that is associated with a lower expected output loss and unemployment in the short run and it tends to be expansionary in the medium run a defense if successful entails insignificant costs in the short run but unlike an immediate depreciation a successful defense is not expansionary in the medium run if a defense fails large output losses and an increase in unemployment ensue at least in the short run

forecasting housing prices under different market segmentation assumptions three types of market segmentation strategies are available to estimate hedonic housing price models i e no segmentation segmentation by using statistical clustering methods and segmentation by using a priori information this research tests the hypothesis of tiebout theory that individual residential decision making is determined by equilibrium provision of local public goods in accord with the tastes and preferences of residents thereby sorting their housing locations into optimal sub markets forecasting accuracies of eight sub market segmentation strategies and two forecast combining methods are examined by using housing sales data from knox county tennessee usa the results provide empirical support for tiebout theory of optimal housing sub market location in that boundaries drawn using a priori information from local government jurisdictions school districts and expert opinions are more closely aligned with the equilibrium provision of local public goods than boundaries drawn by statistical cl

collapsing exchange rate regimes some linear examples abstract we construct a pair of linear examples to study the collapse time of a fixed exchange rate regime the first example is a perfect foresight continuous time model which allows calculation of the exact collapse time and the tracking of reserves the second example is a discrete time stochastic model which yields an endogenous probability distribution over the collapse time and produces a forward discount of the exchange rate

nominal interest rates consumption booms and lack of credibility a quantitative examination abstract exchange rate based stabilization programs in chronic inflation countries have often been accompanied by an initial expansion of private consumption followed by a contraction this consumption cycle has been attributed to lack of credibility in the sense that the public views the reduction in the devaluation rate as temporary this paper assesses the quantitative relevance of the temporariness hypothesis by comparing the predictions of a simple model to the actual figures for seven major programs the paper concludes that nominal interest rates must fall substantially for the temporariness hypothesis to account for an important fraction of the observed consumption booms

borrowing to defend the exchange rate and the timing and magnitude of speculative attacks abstract the paper analyses the implications for the timing and magnitude of a speculative attack on a fixed exchange rate of government borrowing to increase the stock of international reserves it is shown that such borrowing reduces the likelihood of an early collapse and increases the likelihood of an eventual collapse the magnitude of the speculative attack also increases

external sector closing rules in applied general equilibrium models abstract this paper examines formulations of external sector behavior adopted in some of the recent applied general equilibrium models in many cases these models are constructed for single economies and the model builder attempts to use a convenient external sector specification to close the model issues and difficulties with export demand and import supply functions for foreigners which satisfy trade balance and the modeling of small economy price taking behavior are explored

are price controls necessarily bad the case of rice in vietnam abstract most economists instinctive reaction to price controls is that they are harmful its strong enforcement results in shortages and resource misallocation while weak enforcement often leads to black markets and high transaction costs given these instincts this paper assesses the pros and cons of rice price controls in vietnam using a multi sector multi household general equilibrium model these price controls fix producer prices and allow government marketing agencies to sell at higher prices and hence are in part a revenue raising device as such they may be part of an efficient tax mix particularly so since agricultural incomes and production go untaxed under the formal tax system it is argued that such controls can act to dampen costly domestic adjustments in the face of volatile world prices it is shown that this system can be supported as welfare enhancing under conditions currently prevailing in vietnam

stabilization with exchange rate management stabilization programs in open economies typically consist of two stages in the first stage the rate of currency devaluation is reduced but the fiscal adjustment does not eliminate the fiscal deficit that causes growth of debt and loss of reserves making a future policy change necessary only later at a second stage is this followed by either an abandonment of exchange rate management or by a sufficiently large cut in the fiscal deficit we study how different second stage policy changes affect economic dynamics during the first stage these changes include tax increases budget cuts on traded and nontraded goods and increases in the growth rate of money

the recent growth of international reserves in developing economies a monetary perspective abstract the massive accumulation of international reserves in developing economies is a puzzling recent development in the world economy this paper studies reserve accumulation as the outcome of a simple model in which the central bank smooths inflation i explore the view that central banks accumulate reserves to face large fiscal shocks that need monetary financing central bank revenues are obtained through inflation but inflation is distortionary as a result the central bank optimally accumulates international reserves in order to spread the costs associated with inflation over time a simple numerical exercise for an average developing economy using data between 1970 and 2009 yields fast growth of international reserves

the impact of cyclical demand movements on collusive behavior recent work by rotemberg and saloner 1986 investigates the effect of the business cycle on optimal collusive pricing by specifying that demand is subject to i i d shocks an implication of the i i d assumption is that firms expectations on future demand are unrelated to the current level of demand we put forth a model that allows for both the level of current demand and firms expectations on future demand to change over time thus it captures two important properties of the business cycle our analysis reveals that while the gain to deviating from a collusive agreement is greatest during booms firms find it most difficult to collude during recessions as the forgone profits from inducing a price war are relatively low an implication of this effect for pricing behavior is that at the same level of demand price is lower when demand is declining than when demand is rising consistent with previous theoretical work we find that firms price countercyclically for a range of values for the discount factor however numerical simulations reveal a greater tendency for firms to price countercyclically during recessions than during booms

tacit collusion in housing markets the case of santiago chile abstractin this article using a detailed micro database from santiago chile the potential existence of tacit collusion in housing markets is investigated in order to perform the test santiago s housing market is split into four different submarkets using hedonic price analysis and household s socioeconomics characteristics then using a gmm panel data model regressions are run for each submarket correlating industry s markups with the aggregate level of activity the main finding is that low and middle income submarkets present higher average markups and a pro cyclical behaviour this finding is consistent with a market where participants do not face capacity constraints and behave strategically to sustain tacit collusion during increasing demand periods

prospective deficits and the asian currency crisis this paper argues that a principal cause of the 1997 asian currency crisis was large prospective deficits associated with implicit bailout guarantees to failing banking systems the expectation that these future deficits would be at least partially financed by seigniorage revenues or an inflation tax on outstanding nominal debt led to a collapse of the fixed exchange rate regimes in asia we articulate this view using a simple model whose key feature is that a speculative attack is inevitable once the present value of future government deficits rises we present empirical evidence in support of the key assumptions underlying our interpretation of the crisis
