diversification incentives under price based and cost based regulation this article considers two schemes of regulationforfirms that serve both monopoly markets and markets subjected to substantial competition the first form cost based regulation combines elements of rate of return regulation on monopoly markets with filly distributed cost pricing much like the form of regulation currently in place in the domestic telephone industry the secondform price based regulation would establish rate caps on noncompetitive services and allow the firm to enter into competitive markets and charge whatever prices it might like in those markets models of both forms of regulation are developed and analyzed with respect to incentives for cost misreporting choice of technology cost reducing innovation choices of prices and output levels and diversification into competitive markets

the impact of uncertainty shocks in emerging economies abstract a recent strand of research proposes that sudden jumps in uncertainty generate rapid drops and recoveries in real macroeconomic variables that drive the business cycle using an empirical model we find substantial heterogeneity in reactions to these shocks across countries in comparison to the u s and other developed countries emerging economies suffer much more severe falls in investment and private consumption following an exogenous uncertainty shock take significantly longer to recover and do not experience a subsequent overshoot in activity we provide evidence that the dynamics of investment and consumption are correlated with the depth of financial markets we control for the potential role of a credit channel and estimate that it can account for up to one half of the increased fall in investment generated by uncertainty shocks among emerging economies with less developed financial markets in this context monetary and fiscal policy actions that alleviate the impact of credit constraints facing firms may reduce the impact of uncertainty shocks in these economies

liberalization of capital movements and of the domestic financial system this paper analyzes the dynamic impact of a joint liberalization of capital movements and of the domestic financial sector both a simultaneous and a sequential liberalization are examined in an overlapping generations model with a q theory of investment a liberalization generally leads to an initial period of capital inflows followed by capital outflows it also increases investment and causes an overshooting in share prices furthermore the interest rate level before a liberalization will usually not indicate the direction of net capital flows copyright 1992 by the london school of economics and political science

dollarization bailouts and the stability of the banking system central bank policy suffers from time inconsistency when facing a banking crisis a bailout is optimal ex post but ex ante it should be limited to control moral hazard dollarization provides a credible commitment not to help at the cost of not helping even when it would be ex ante optimal to do so dollarization is good when the costs of establishing a reputation for the central bank are high monitoring effort by the banker is important in improving returns and when the cost of liquidating projects is moderate however a very severe moral hazard problem could make dollarization undesirable the results obtained are applied to assess the desirability of dollarization in a range of countries and the potential role of the imf as international lolr we would never put ourselves in a position where we envisioned actions that we would take would be of assistance to the rest of the world but to the detriment of the united states alan greenspan to a congressional panel in 1999 iht january 19 2000

financial integration credit market imperfections and consumption smoothing abstract contrary to standard theoretical reasoning recent empirical research shows that financial integration is associated with higher consumption volatility in developing countries this paper illustrates how domestic credit market imperfections can alter the standard predictions about the consumption smoothing possibilities under financial autarky and international financial integration i use a two country international real business cycle model where the non traded sector in the small country faces borrowing constraints due to contract enforceability problems if the international risk sharing opportunities are non existent households can secure themselves against the shocks in the non traded sector only by adjusting their labor effort which leads to changes in sectorial output and terms of trade the deterioration of the terms of trade acts as a dampening effect on consumption causing it to be less volatile under financial autarky relative to financial integration under financial integration international financial assets provide the insurance against domestic productivity shocks without affecting the relative prices hence allowing the consumption to react more

the assessment competition policy the paper advances four propositions concerning the objectives content and institutions of competition policy first the role of policy should be to advance economic efficiency rather than competition for its own sake or some wider definition of the public interest second economic analysis is generally ambiguous a priori about the efficiency effects of particular market structures and conduct third the design of policy and institutions needs to reflect this ambiguity policy rules are essential but there should be scope for parties to argue countervailing efficiency benefits a policy institution should be empowered to identify investigate and propose remedies for failures of competition subject to review by an independent competition tribunal fourth international harmonization of competition policies is essential current policies in the u k and ec and relationships between the two are evaluated and the case made for a radical reform of u k policy copyright 1993 by oxford university press

microeconomic adjustments in uruguay during 1973 1981 the interplay of real and financial shocks abstract this paper uses the financial statements of industrial firms to develop an integrated firm s eye view of the changes in the uruguayan economy during 1973 1981 in the first of three subperiods 1973 1975 real financial costs were very negative and tended to offset low returns on operating assets during 1976 1978 the dismantling of interest rate controls increased real financial costs but other factors increased the returns on operating assets more rapidly during 1979 1981 financial costs jumped enough to more than absorb increases in gross earnings which were probably due to argentine demand the rates of earning and capital formation were highest among exporters in the second subperiod when a major export promotion program was in place this pattern was reversed in the third subperiod as the promotion programs were dismantled and real currency appreciation seemed to squeeze gross earnings of exportables relatively more this unequal squeezing was probably due to redundant tariff and other protection for import competing producers

capital markets and the exchange rate with special reference to the dollarization debate in latin america the paper reviews the main challenges faced by policymakers in emerging market economies em in light of recent financial crises and taking into account salient factors like the existence of partial dollarization imperfect credibility weak financial systems and contagion the standard theory of optimal currency areas is discussed and criticized for omitting the above factors when these factors are taken into account an extreme foreign exchange regime like dollarization is shown to become much more attractive the paper discusses the pros and cons of dollarization and among other things shows that the lack of a lender of last resort is not necessarily a major drawback in em the paper also discusses inflation targeting it in a formal model it is shown that it could be subject to credibility problems similar to those found in exchange rate based stabilization programs

lending booms latin america and the world recent theories of crisis put lending booms at the root of financial collapses yet lending booms may be a natural consequence of economic development and fluctuations so are lending booms dangerous in this paper we investigate empirically this question using a broad sample of lending boom episodes over 40 years with a special eye for latin america our results indicate that 1 lending booms are often associated with i a domestic investment boom ii an increase in domestic interest rates iii a worsening of the current account iv a declines in reserves v a real appreciation vi a decline in output growth 2 typical lending booms do not increase substantially the vulnerability of the banking sector or the balance of payments comparing latin america and the rest of the world we find that latin america lending booms make the economy considerably more volatile and vulnerable to financial and balance of payment crisis

entrepreneurship financiership and selection we develop an equilibrium model of the market for entrepreneurial finance in which all agents have some personal wealth and a project whose quality is their private information all agents choose whether to invest either as entrepreneurs or financiers or to invest in storage technology we find that a binding economy level wealth constraint which renders credit scarce can create advantageous selection where productive agents become entrepreneurs and unproductive agents become their financiers if funding is easier to obtain entrepreneurship also attracts unproductive agents in our model individual wealth and entrepreneurship are positively negatively correlated if financial market participation is complete incomplete

measuring macroeconomic instability a critical survey illustrated with exports series for at least 40 years the analysis of the causes and consequences of macroeconomic instability has greatly deepened our understanding of the handicaps faced by developing countries this concern on economic instability is evidenced by a broad spectrum of indicators based on the deviation of observed values of a given economic aggregate from its reference or trend value in general the choice of this or that indicator is not discussed advocating that the resulting instability indicators are closely correlated focusing on measurements of instability in export revenue data for 134 countries from 1970 to 2005 this paper finds that this assertion may be true for variancebased indicators measuring the average magnitude of deviations from the trend however great discrepancies may arise between different measures of the asymmetry or of the occurrence of extreme deviations around the trend when different trend computation methods are used our purpose is therefore to invite further discussions regarding the use of these indicators and to highlight the different dimensions of instability which have been so far unheeded by the economic literature

exchange rate based stabilization with endogenous fiscal response abstract this paper studies the dynamics of inconsistent exchange rate based stabilization policy a policy that fixes the exchange rate without an underlying fiscal adjustment to ensure that the exchange rate policy is sustainable in the long run in a model where the perception that exchange rate policy temporarily leads to an initial expansion in consumption that generates an increase in tax revenues large enough to eliminate the ex ante fiscal deficit therefore an ex ante inconsistent stabilization program displays ex post all the features of a fiscally consistent one i e a fixed exchange rate and no fiscal deficit in contrast to the standard results where the inconsistency between fiscal and exchange rate policy leads to a steady loss of international reserves and culminates in a krugman type balance of payments crisis this model predicts that along the path towards the balance of payments crisis the economy displays no fiscal deficit and enjoys increasing international reserves

when liberal policies reflect external shocks what do we learn abstract we present a model where policies of free capital mobility can signal governments future policies but the informativeness of the signal depends on the path of world interest rates capital flows to emerging markets reflect investors perception of these markets political risk with low world interest rates emerging markets experience a capital inflow and engage in a widespread policy of free capital mobility with higher rates only sufficiently committed countries allow free capital mobility whereas others impose controls to trap capital onshore thus signaling future policies affecting capital mobility these predictions are consistent with the recent experience of capital flows and policies affecting capital mobility in developing countries

hedging and financial fragility in fixed exchange rate regimes currency crises that coincide with banking crises tend to share at least three elements first banks have a currency mismatch between their assets and liabilities second banks do not completely hedge the associated exchange rate risk third there are implicit government guarantees to banks and their foreign creditors this paper argues that the first two features arise from banks optimal response to government guarantees we show that guarantees completely eliminate banks incentives to hedge the risk of a devaluation our model also articulates one reason why governments might be tempted to provide guarantees to bank creditors guarantees lower the domestic interest rate and lead to a boom in economic activity but this boom comes at the cost of a more fragile banking system in the event of a devaluation banks renege on foreign debts and declare bankruptcy

are financial development and trade openness complements or substitutes this article studies the long and short run relationships between financial development and trade openness using the pooled mean group estimator of pesaran shin and smith 1999 for unbalanced panel data for 87 countries over the 1960 2005 period our empirical results indicate that long run complementarity between financial development and trade openness coexists with short run substitutionarity between the two policy variables but when splitting the data into oecd and non oecd country groups this finding can be observed only in non oecd countries for oecd countries financial development has negligible effects on trade in addition we find nonlinearity in the relationship in that long run responses of trade decrease with financial development the article further finds coexistence of negative trade effects of financial fragility and positive trade impacts of financial depth

reputation and imperfect information abstract a common observation in the informal literature of economics and elsewhere is that is multistage games players may seek early in the game to acquire a reputation for being tough or benevolent or something else but this phenomenon is not observed in some formal game theoretic analyses of finite games such as selten s finitely repeated chain store game or in the finitely repeated prisoners dilemma we reexamine selten s model adding to it a small amount of imperfect or incomplete information about players payoffs and we find that this addition is sufficient to give rise to the reputation effect that one intuitively expects

north south lending and endogenous domestic capital market inefficiencies abstract we develop an open economy model of intertemporal trade under asymmetric information capital market imperfections are endogenous and depend on a country s stage of economic development relative to the perfect information benchmark north south capital flows are dampened and possibly reversed and world interest rates are lower whereas riskless rates are equalized across borders the domestic loan rate is higher in poorer countries the model can be applied to a number of policy issues including the debt overhang problem the indexation of foreign public debts and the effect of income distribution on growth

estimation of technical inefficiency in panel data models with firm and time specific effects abstract this paper uses a panel data model and develops methods to estimate production function parameters and technical inefficiency the model distinguishes technical inefficiency from firm and time specific effects determinants of technical inefficiency is introduced by allowing its mean to be a function of exogenous variables both random and fixed effects treatment of firm and time specific effects are considered in estimation

shareholder protection compulsory acquisition and the efficiency of the takeover process this paper examines public good problems connected with takeovers two broad categories of exclusion device oppression of minority interests and compulsory acquisition of shares are evaluated it is argued that inability to control the level of oppression with any precision renders the first method unsatisfactory from the policy viewpoint but that strong protection of minorities coupled with compulsory acquisition rights for the acquiror can straightforwardly generate an efficient solution to the public good problems it is shown that in the u k company law and the city code on takeovers and mergers combine to produce an approximation to this efficient solution against managements which are performing poorly in the eyes of the capital market and since the work of marris 1964 this incentive mechanism has come to play a prominent role in the economic analysis of company behaviour the usual argument is that as the market value of a particular company falls relative to the level that it is generally believed could be obtained by other managers following different policies the firm becomes increasingly vulnerable to a takeover by a raider attracted by the prospect of the capital gains that would ensue following managerial changes in turn the threat to the incumbent managers acts as a deterrent to behaviour which runs counter to shareholders interests the effectiveness of the workings of the takeover mechanism is therefore of some importance for the efficient utilisation and allocation of resources potential obstacles to the smooth functioning of the takeover process have however been recognised for quite some time as long ago as 1926 the greene committee on company law reform identified cases where a takeover had been inhibited by the actions of small minorities of shareholders much more recently grossman and hart 1980 have formalised some of the earlier points in a way that clearly highlights one of the major difficulties that freeriding strategies on the part of shareholders in firms with dispersed share ownership can prevent successful bids the argument is that shareholders of the target company believing their own actions have a trivially small effect on

modelling cost structure the bell system revisited this paper analyses a recent public policy decision and the crucial role played by the choice of the functional form the break up of the bell system is indeed a classic case of anti trust settlement and constitutes one of the most prominent and controversial applications of microeconomics to public policy it is argued that demanding multi output cost properties such as economies of scope for this is the considerable robustness problem displayed by the tranlog cost functional form the reason for this is the considerable able to robustness problem displayed by the translog cost function which is the source underlying many of the expert disagreements it is suggested that the non robustness is due to what ils termed the flip flop property and it is shown that the available empirical evidence from the pre divestiture bell system supports this argument to obtain robust results we propose that the analysis is constrained to the proper region of the cost function we propose that the analysis is con

dualism and macroeconomic volatility this paper develops a simple macroeconomic model that shows that combining capital market imperfections together with unequal access to investment opportunities across individuals can generate endogenous and permanent euctuations in aggregate gdp investment and interest rates reducing inequality of access may be a necessary condition for macroeconomic stabilization moreover countercyclical escal policies have a role to play in our model savings are underutilized in slumps because of the limited debt capacity of potential investors therefore the government should issue public debt during recessions in order to absorb those idle savings and enance investment subsidies or tax cuts for investors the most important single fact about saving and investment activities is that in our industrial society they are generally done by different people and for different reasons for years there might tend to be too little investment leading to deeation losses excess capacity and unemployment for other years there might tend to be too much investment leading to periods of chronic ineation unless prudent and proper public policies in the escal and monetary eelds are followed paul a samuelson economics 8th edition 1970 pp 196 198

corporate dollar debt and depreciations much ado about nothing abstract emerging markets firms often carry foreign currency debt on their balance sheets following a depreciation the expanding peso value of dollar liabilities could via a net worth effect offset the expansionary competitiveness effect to assess which effect dominates we use accounting data including the currency composition of liabilities for 450 nonfinancial firms in five latin american countries in the 1990s we find that firms holding more dollar debt do not invest less than their peso indebted counterparts following a depreciation we also show that these firms match the currency denomination of their liabilities with the exchange rate sensitivity of their profits

mexico s balance of payments crisis a chronicle of a death foretold this paper claims that the roots of mexico s balance of payments crisis are found in the prevailing high degree of capital mobility and financial globalization under these circumstances shifts in foreign capital flows and anticipation of a banking system bailout may produce large imbalances between stocks of financial assets and foreign reserves threatening the sustainability of currency pegs econometric analysis suggests that half of mexico s reserve losses could be accounted for by these phenomena large financial imbalances are also fertile ground for self fulfilling prophesy crises which lead devaluations to produce deep recessions these difficulties can be partly remedied by appropriate policies

financial intermediation and regime switching in business cycles the authors study a one sector growth model where capital investment is credit financed and there is an adverse selection problem in credit markets the presence of adverse selection creates an indeterminacy of equilibrium many equilibria display permanent fluctuations characterized by transitions between walrasian regimes and regimes of credit rationing cyclical contractions involve declines in real interest rates increases in credit rationing and withdrawals of savings from banks for some configurations of parameters all equilibria display cyclical fluctuations the authors provide sufficient conditions for deterministic cycles consisting of m periods of expansion followed by n periods of contraction to exist copyright 1998 by american economic association

mundell s trilemma policy trade offs within the middle ground abstract mundells s trilemma makes strong categorial predictions on monetary policy trade offs where a small economy either has to adopt floating exchange rates or a closed capital account to establish interest rate autonomy however the trilemma is silent about a functional description of respective trade offs for intermediate middle ground policies accounting for the entire space of such policies we study monetary autonomy in an unrestricted and continuous manner for 20 mostly developed economies evidence suggests that interest rate dependence almost linearly increases with the fx stability indicator under financial openness thereby full independence would require an intensity of fx volatility which policymakers might hardly accept however this strong trade off can be relaxed efficiently by a moderate reduction of financial openness hence such a policy might offer some protection against the global financial cycle and leaves a considerable scope to combine a domestic monetary policy with a reduced fx rate variability

microeconomic adjustments in chile during 1977 1981 the importance of being a grupo abstract this paper uses the financial statements of industrial firms to provide an integrated firm level view of the changes in the chilean economy during 1977 1981 both real side and financial shocks had major effects on the performance of some types of firms exportable goods producers did relatively poorly in real activities for reasons probably tied to chile s real prolonged exchange rate appreciation import competing firms that began the period with high protection did even worse apparently reflecting the larger change in their output prices as protection was dismantled the reforms thus shifted demand away from industries least in line with the country s comparative advantage but they also hurt exportables the very sector authorities intended to promote on the financial side the highly positive real cost of peso borrowing reduced industrial profits considerably a handful of powerful conglomerates grupos generated large but presumably unrealized capital gains by investing in the securities of related enterprises such activities allowed them to offset relatively poor returns on real operations and their ownership of the country s major banks allowed them to consolidate control of a large volume of assets with debt finance these two results explain why the grupos were suddenly in considerable financial difficulty when the chilean boom ended in 1982

a counterfactual analysis of the argentinian monetary transformation in 2002 a hard peg restored economic stability in argentina during the nineties but made it also vulnerable to real shocks in so far as the economy was highly dollarized a devaluation in 1998 in brasil its main partner damaged the argentinian competitiveness and resulted in a fall in export demand there was a need for a real adjustment but removing the peg would have implied large balance sheet effects and raised serious financial issues this article endeavours to learn a lesson about the aftermath of hard peg regime from the argentinian experience it is based on a dynamic macroeconomic model to assess the impact of three scenarios already suggested in the literature two hypothetical a floating regime and dollarization and one which was actually implemented in 2002 the pesification of the whole economy the simulations suggest that pesification was the only scenario with unambiguous expansionary effects

do capital market imperfections exacerbate output fluctuations abstract we develop a dynamic general equilibrium macroeconomic model where a proportion of firms are credit constrained due to asymmetric information in general a macroeconomic shock has additional effects created by a reallocation of funds between credit constrained and unconstrained firms as they have different marginal productivities we show however that the output response to shocks is not necessarily amplified and can be dampened by the presence of asymmetric information this depends on the impact of the shock on the composition of external and internal funds for credit constrained firms

costly gains to breaking up lecs and the baby bells while the divestiture of at t was intended to produce benefits in the long distance market the evidence suggests it has created an unexpected side benefit in local telephone markets the authors results show that local exchange carriers have realized immediate cost savings in responding to competitive pressures since the breakup with the baby bells experiencing generally larger gains dynamically these productivity gains have increased over time at a relatively constant rate although gains of 3 5 percent of total cost are not that large the absolutely large costs of telephone companies imply significant cost savings of nearly 72 million for the representative firm copyright 1993 by mit press

temporary stabilization predetermined exchange rates the paper analyzes the impact of a stabilization policy based on a temporary reduction in the rate of devaluation against a background in which a constant rate of devaluation has no real effects it is shown that the temporary policy does and furthermore that the real effects tend to become bigger in absolute value as the horizon of the temporary policy is shortened the central discussion is carried out in terms of a one good cash in advance model with perfect capital mobility and ramsey type consumers results are extended to account for home goods and variable velocity the roles of capital mobility and banking liberalization are briefly discussed

a test for cross subsidies in local telephone rates do business customers subsidize residential customers recent regulatory and technological changes suggest that the local telecommunications market may soon present opportunities for profitable entry bypass activity by businesses combined with the generally higher business rates suggests that business service revenues may be subsidizing residential access to the local network before regulators allow wide scale entry into local telecommunications they need to know if local phone service rates exhibit cross subsidies using data supplied by new england telephone this article tests a new set of sufficient conditions for cross subsidization that do not require observations on stand alone cost the results indicate that business service revenues subsidize residential service provision at nearly 65 of the suburban central offices the sufficient conditions for a residential to business cross subsidy fail for all central offices in the sample

determinants and costs of current account reversals under heterogeneity and serial correlation using large panel data sets for analysis of determinants and costs of reversals asks for controls of latent heterogeneity among countries this article performs a bayesian analysis which allows for a parsimonious yet flexible handling of country specific heterogeneity via random coefficients and serially correlated errors consideration of persistence within the employed macroeconomic data is important to gauge the impact of explaining variables suggested by theory correctly bayesian specification tests provide evidence in favour of models incorporating heterogeneity and serial correlation the results suggest that costs of reversals are overestimated when country specific heterogeneity is neglected and stress the importance of external variables in explaining current account reversals results are checked for robustness against the underlying reversal definition

currency crises and monetary policy in an economy with credit constraints this paper presents a simple model of currency crises which is driven by the interplay between the credit constraints of private domestic firms and the existence of nominal price rigidities the possibility of multiple equilibria including a currency crisis equilibrium with low output and a depreciated domestic currency results from the following mechanism if nominal prices are sticky a currency depreciation leads to an increase in the foreign currency debt repayment obligations of firms and thus to a fall in their profits this reduces firms borrowing capacity and therefore investment and output in a credit constrained economy which in turn reduces the demand for the domestic currency and leads to a depreciation we examine the impact of various shocks including productivity fiscal or expectational shocks we then analyze the optimal monetary policy to prevent or solve currency crises we also argue that currency crises can occur both under fixed and flexible exchange rate regimes as the primary source of crises is the deteriorating balance sheet of private firms

intertemporal budget policies and macroeconomic adjustment in a small open economy abstract this paper analyzes the role of nominal assets in ranking intertemporal budget policies in a growing open economy budget policies are ranked in terms of the public s intertemporal tax liability in our small open economy model the constraint for the valuation of private and public financial assets is in terms of the exogenous foreign price level we show that this limits under purchasing power parity the scope of the government to influence the real value of financial assets using fiscal and monetary policy instruments

behavior of the firm under regulatory constraint a recent article by akira takayama discusses an earlier paper by harvey averch and leland l johnson on fair rate of return regulation of public utilities although takayama p 255 agrees with averch and johnson s general conclusions that a firm will tend to increase its investment with the introduction of an active constraint on its rate of return he criticizes the a j argument as being confusing ambiguous and in error takayama then attempts a clarification and presents a new formulation which leads to the a j result quoted above this comment will discuss several of takayama s criticisms in addition to showing that the so called a j effect cannot be derived from the basic assumptions made by both averch and johnson and takayama 1 we will show that the very assumptions used to prove the a j effect by defining the region of x require an assumption that the a j effect exists in the first place

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

economic adjustment and exchange rates in developing countries in spite of the attention paid exchange rates in recent economic debates on developing countries relatively few studies have systematically analyzed in detail the various ramifications of exchange rate policy in these countries in this new volume from the national bureau of economic research leading economists use rigorous models to tackle various exchange rate issues while also illuminating policy implications that emerge from their analyses the volume divided into four main sections addresses the role of exchange rates in stabilization programs and the adjustment process the importance of exchange rate policy during liberalization reform in developing countries exchange rate problems relevant and unique to developing countries illustrated by case studies and the problems defining measuring and identifying determinants of real exchange rates authors of individual papers examine the relation between commercial policies and exchange rates the role of exchange rate policy in stabilization programs the effectiveness of devaluations as a policy tool and the interaction between exchange rate terms of trade an capital flow this research will not only prove crucial to our understanding of the role of exchange rates in developing countries but will clearly set the standard for future work in the field

why higher takeover premia protect minority shareholders posttakeover moral hazard by the acquirer and free riding by the target shareholders lead the former to acquire as few sharcs as necessary to gain control as moral hazard is most severe under such low ownership concentration inefficiencies arise in successful takeovers moreover share supply is shown to be upward sloping rules promoting ownership concentration limit both agency costs and the occurrence of takeovers furthermore higher takeover premia induced by competition translate into higher ownership concen tration and are thus beneficial finally one share one vote and simple majority are generally not optimal and socially optimal rules need not emerge through private contracting

unnatural monopolies in local telephone we attempt to overcome the serious data problems of past telecommunications cost studies by focusing on local exchange carriers lecs with enough degrees offreedom to yield precise estimates our global subadditivity tests show that the cost function is definitely not subadditive the results suggest that the benefits to breaking up the monopoly outputs of existing lecs substantially outweigh the potential losses in efficiency they also support permitting entry and increasing competition in local exchange markets furthermore given the competitive nature of long distance service it is doubtful that the predivestiture bell system was a natural monopoly

rational contagion and the globalization of securities markets this paper argues that globalization may promote contagion by weakening incentives for gathering costly information and by strengthening incentives for imitating arbitrary market portfolios in the presence of short selling constraints the gain of gathering information at a fixed cost may diminish as markets grow moreover if a portfolio manager s marginal cost for yielding below market returns exceeds the marginal gain for above market returns there is a range of optimal portfolios in which all investors imitate arbitrary market portfolios and this range widens as the market grows numerical simulations suggest that these frictions can have significant implications for capital flows in emerging markets

distinguished lecture on economics in government exchange rate regimes is the bipolar view correct the choice of appropriate exchange rate regime which for economies with access to international capital markets increasingly means a move away from the middle ground of pegged but adjustable fixed exchange rates towards the two corner regimes of either flexible exchange rates or a fixed exchange rate supported if necessary by a commitment to give up altogether an independent monetary policy lawrence h summers 2000 p 8

microeconomic adjustments in argentina during 1976 1981 the importance of changing levels of financial subsidies abstract this paper uses the financial statements of argentine industrial firms to study the micro level impact of recent liberalization and reform attempts the main lesson is that extremely large subsidies were provided to the industrial sector by way of negative effective financial costs these negative costs appeared first in the late 1970s because of real currency appreciation and unconstrained access to foreign credit then again in 1981 because of an exchange insurance program we also find that the argentine government s announced intention to promote exporting activities did not translate into relatively favorable product market conditions for exporting firms to the contrary the real currency appreciation squeezed exporters profits while redundant tariff protection insulated import competing firms from world competition at least until 1980

thresholds in the process of international financial integration abstract the financial crisis has re ignited the fierce debate about the merits of financial globalization and its implications for growth especially for developing countries the empirical literature has not been able to conclusively establish the presumed growth benefits of financial integration indeed a new literature proposes that the indirect benefits of financial integration may be more important than the traditional financing channel emphasized in previous analyses a major complication however is that there seem to be certain threshold levels of financial and institutional development that an economy needs to attain before it can derive the indirect benefits and reduce the risks of financial openness in this paper we develop a unified empirical framework for characterizing such threshold conditions we find that there are clearly identifiable thresholds in variables such as financial depth and institutional quality the cost benefit trade off from financial openness improves significantly once these threshold conditions are satisfied we also find that the thresholds are lower for foreign direct investment and portfolio equity liabilities compared to those for debt liabilities

finance and inequality the case of india although theory emphasizes the role of financial market frictions in explaining income inequality there is little empirical research exploring how financial development and financial sector reforms influence the evolution of income inequality this article examines how finance impacts income inequality in india using annual time series data for over half a century the results indicate that while financial development helps reduce income inequality financial liberalization seems to exacerbate it the results are robust to the use of different measures for financial development and financial liberalization although the relationship between financial development and economic growth has been extensively studied in the literature see for example king and levine 1993 demetriades and hussein 1996 arestis and demetriades 1997 levine loayza and beck 2000 bell and rousseau 2001 ang and mckibbin 2007 little is known about how finance impacts income inequality the importance of the finance inequality relationship has recently been highlighted in an insightful survey article by claessens and perotti 2007 they indicate that while financial development can help reduce income inequality financial liberalization captured by established interests may do the opposite the theoretical predictions of the effects of finance on income inequality are controversial rajan and zingales 2003b argue that improvements in the formal financial sector primarily benefit the rich greenwood and jovanovic 1990 predict a nonlinear relationship between financial development and income inequality where it is hypothesized that income inequality first increases with the degree of sophistication in the financial systems then stabilizes and eventually declines others propose that the presence of financial market imperfections deters the poor from borrowing adequately to invest in human and physical capital implying that financial development helps alleviate income inequality banerjee and newman 1993 galor and zeira 1993 aghion and bolton 1997 mookherjee and ray 2003 2006 given that theories provide ambiguous predictions regarding the effects of finance on the distribution of income it is useful to approach the issue at the empirical level this could facilitate our understanding of the relationship between finance and inequality and help us to assess the validity of each theoretical model despite the important role of financial market frictions in the theories of poverty and income inequality researchers so far have not adequately addressed whether financial

privatization in theory and practice privatization george yarrow this paper examines the theoretical and empirical case for private versus public ownership privatization usually leads managers to place greater emphasis on the pursuit of profits however whether this is beneficial to society depends on the trade off between possible market failures due to a lack of competition and deficiencies in government control of public firms the competitive and regulatory environment is more important than the question of ownership per se in competitive markets there is a presumption in favour of private ownership where there is a natural monopoly vigorous regulatory action is required the evidence suggests that privatization has led to improved performance by firms such as the national freight corporation and cable and wireless which operate in a relatively competitive environment the benefits are less clear in the case of firms like bp britoil and british aerospace however the most worrying case is that of british telecom and the projected privatization of british gas where little thought has been given to limiting the abuse of monopoly power rather the regulatory environment has been tailored to the needs of the existing management and to ensuring a successful share flotation privatization is also advanced as a weapon for reducing trade union power encouraging wider share ownership redistributing wealth and improving the public finances however there are other policy instruments better suited to achieving these objectives the existing privatization programme has not led to a marked widening of share ownership and has resulted in windfall gains to a small group of investors at the expense of taxpayers in general

the transmission of disturbances under alternative exchange rate regimes with optimal indexing the paper develops a general stochastic macroeconomic model that can be used to study the international transmission of disturbances under four alternative exchange rate systems uniform flexible exchange rates uniform fixed exchange rates and two versions of two tier exchange rates the analysis makes two general points first one cannot assume stability of structure when assessing the consequences of alternative exchange rate regimes for example the slope of the aggregate supply curve and the rationally formed expectations in the asset markets can respond dramatically to the government s choice of exchange rate regime second exchange rate regimes that provide full insulation from foreign disturbances may nevertheless be inferior to other regimes in terms of their ability to maximize social welfare

international capital flows and credit market imperfections a tale of two frictions the nancial crisis of 2007 08 has underscored the importance of adverse selection in nancial markets this friction has been mostly neglected by macroeconomic models of nancial imperfections however which have focused almost exclusively on the eects of limited pledgeability in this paper we ll this gap by developing a standard growth model with adverse selection our main results are that by fostering unproductive investment adverse selection i leads to an increase in the economy s equilibrium interest rate and ii it generates a negative wedge between the marginal return to investment and the equilibrium interest rate under nancial integration we show how this translates into excessive capital inows and endogenous cycles we also extend our model to the more general case in which adverse selection and limited pledgeability coexist we conclude that both frictions complement one another and show that limited pledgeability exacerbates the eects of adverse selection

financial development and the instability of open economies this paper introduces a framework for analyzing the role of financial factors as a source of instability in small open economies our basic model is a dynamic open economy model with a tradeable good produced with capital and a country specific factor we also assume that firms face credit constraints with the constraint being tighter at a lower level of financial development a basic implication of this model is that economies at an intermediate level of financial development are more unstable than either very developed or very underdeveloped economies this is true both in the sense that temporary shocks have large and persistent effects and also in the sense that these economies can exhibit cycles thus countries that are going through a phase of financial development may become more unstable in the short run similarly full capital account liberalization may destabilize the economy in economies at an intermediate level of financial development phases of growth with capital inflows are followed by collapse with capital outflows on the other hand foreign direct investment does not destabilize

why countries differ in thin capitalization rules the role of financial development abstract the purpose of thin capitalization rules is to limit multinational firms possibilities of engaging in tax planning via debt shifting this paper analyzes the optimal design of thin capitalization rules in the presence of financial frictions when a host country in the first stage chooses the type of thin capitalization rule and then in the second stage decides about the strictness we show that welfare under a safe haven rule is higher than under an earnings stripping rule if firms are not able to manipulate the interest rate on internal loans welfare however can be higher under an earnings stripping rule if firms are able to manipulate the interest rate on internal loans we also show that the optimal level of internal interest deductions decreases with the financial development of the host country our results are consistent with countries actual policy choice

a corporate balance sheet approach to currency crises this paper presents a general equilibrium currency crisis model of the third generation in which the possibility of currency crises is driven by the interplay between private firms credit constraints and nominal price rigidities despite our emphasis on microfoundations the model remains sufficiently simple that the policy analysis can be conducted graphically the analysis hinges on four main features i ex post deviations from purchasing power parity ii credit constraints a la bernanke gertler iii foreign currency borrowing by domestic firms iv a competitive banking sector lending to firms and holding reserves and a monetary policy conducted either through open market operations or short term lending facilities we derive sufficient conditions for the existence of a sunspot equilibrium with currency crises we show that an interest rate increase intended to support the currency in a crisis may not be effective but that a relaxation of short term lending facilities can make this policy effective by attenuating the rise in interest rates relevant to firms

a pecking order of capital inflows and international tax principles abstract even though financial markets today show a high degree of integration the world capital market is still far from the textbook story of high capital mobility the purpose of this paper is to highlight key sources of market failure in the context of international capital flows and to provide guidelines for efficient tax structure in the presence of capital market imperfections the analysis distinguishes three types of international capital flows foreign portfolio debt investment foreign portfolio equity investment and foreign direct investment the paper emphasizes the efficiency of a non uniform tax treatment of the various vehicles of international capital flows

on the flexibility of monetary policy the case of the optimal inflation tax this paper examines optimal monetary policy under uncertainty in a context in which policy makers are able to make credible policy commitments we study an optimal taxation problem of minimizing the social cost of financing a stochastic and exogenous level of government transfers since in the basic model the welfare costs of inflation derive only from expected inflation the optimal monetary policy is highly responsive to the state of nature in a benchmark case in which all shocks are transitory the optimal policy calls for loading all the variability of government transfers on the shoulders of the inflation tax

international and domestic collateral constraints in a model of emerging market crises abstract we build a model of emerging markets crises which features two types of collateral constraints firms in a domestic economy have limited borrowing capacity from international investors they also have limited borrowing capacity with respect to each other we study how the presence and changes in these collateral constraints affect financial and real variables a binding international constraint in the aggregate leads to a sharp rise in interest rates and fire sales of domestic assets while limited domestic collateral can lead to wasted international collateral these two collateral constraints can interact in important ways the first is disintermediation a fire sale of domestic assets causes banks to fail in their function of reallocating resources across the economy leading to wasted international collateral the second is a dynamic effect we show that firms in an economy with limited domestic collateral and a binding international collateral constraint will not adequately precaution against adverse shocks increasing the severity of these shocks

currency mismatches and monetary policy a tale of two equilibria we develop a model of a small economy whose residents choose whether to borrow in domestic or foreign currency the central bank in turn chooses fixed or flexible exchange rates taking the currency denomination of debts as given we characterize the simultaneous determination of portfolios and exchange rate regime both floating and fixed rates can occur as equilibrium outcomes fear of floating may emerge endogenously and in association with a currency mismatch in assets and liabilities if equilibria with both fixed rates and floating rates coexist the latter is pareto superior lessons for current de dollarization proposals are discussed

inflation targeting and exchange rate management in less developed countries abstract we analyze coordination of monetary and exchange rate policy in a two sector model of a small open economy featuring imperfect substitution between domestic and foreign financial assets our central finding is that tight management of the exchange rate greatly enhances the efficacy of inflation targeting in a flexible exchange rate system inflation targeting incurs a high risk of indeterminacy moreover small inflation shocks may escalate into much larger increases in inflation ex post both problems disappear when the central bank fixes the path of the nominal exchange rate or leans heavily against the wind in a managed float

additive general error models for production cost and derived demand or share systems many empirical studies of production specify a deterministic model of the firm derive the implied behavioral equations input demand or share system and then embed this system in a stochastic framework by tacking on linear error terms in contrast this paper proposes general error models gems in which the error specification is an integral part of the optimization model these models are the statistical embodiment of stigler s view that apparent observed inefficiencies reflect the investigator s ignorance of the true optimization problem additive gems are proposed and interpreted specification tests indicate that a translog additive gem is superior to the standard translog specification

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

a goal programming constrained regression review of the bell system breakup the recently implemented court decision to break up bell american telephone telegraph co to accord with u s anti trust laws represents a highly significant policy decision which is proving to be influential in other countries as well as the u s the telecommunication industry is of such size and importance that even relatively small economies that might be lost with bell s breakup as a natural monopoly could involve substantial welfare losses to consumers and producers studies commissioned by the u s justice department that approached this topic by econometric methods reported that the evidence failed to support the contention that bell was a natural monopoly here a goal programming constrained regression as developed in the management science literature uses the same functional form and the same data but nevertheless reverses the main findings of the econometric studies in every one of the 20 years covered this kind of difference in results obtained by two different methods of analysis poi

freeze out mergers do freeze out mergers mitigate the free rider problem of corporate takeovers we study this question in a tender offer model with finitely many shareholders under a freeze out merger minority shareholders expect to receive the original offer price whether or not they tender their shares we show that the ability to freeze out shareholders increases the raider s expected profit however as the number of shareholders gets arbitrarily large the raider s expected profit in equilibrium converges to zero for any freeze out clause with an ownership threshold that is strictly above simple majority in this sense freeze out mergers do not solve the free rider problem received september 17 2016 editorial decision june 3 2018 by editor francesca cornelli

information in tender offers with a large shareholder we study takeovers of firms whose ownership structure is a mixture of minority block holders and small shareholders we show that the combination of dispersed private information on the side of small shareholders and the presence of a large shareholder can facilitate profitable takeovers furthermore our analysis implies that even if some model of takeovers predicts a profit for the raider for example due to private benefits the profit will be underestimated unless the large shareholder and the dispersion of information among the small shareholders are modeled

what drives credit dollarization in transition economies abstract this paper provides an in depth analysis of the use of foreign currencies in the lending activities of banks in transition economies the impact of bank and firm variables on credit dollarization is studied in an optimal portfolio allocation model and estimated using new aggregate data for 21 transition economies for the period 1990 2003 empirical results provide evidence that credit dollarization is the combined outcome of domestic deposit dollarization and banks desire for currency matched portfolios beyond regulatory requirements the effects of international financial factors and natural hedges are less robust across alternative specifications the paper further discusses the role of regulations in affecting the impact of these factors on credit dollarization and calls for more developed domestic forward foreign exchange markets

the bell system divestiture deregulation and the efficiency of the operating companies abstract a variety of casual evidence has been offered in measurement of the efficiencies and inefficiencies thought to flow from the bell system divestiture and accompanying state regulatory reforms to address several questions in this regard we estimate a regulated cost function for local exchange services using panel data on the divested bell operating companies bocs divestiture and regulatory reform are found to have produced significant efficiencies as of 1993 saving about 20 percent in cost relative to what would have obtained in the absence of these events more specifically to 1993 the divestiture yielded savings of 115 4 billion and state level regulatory reform yielded a slightly smaller 96 7 billion in savings both measured in 1993 dollars output augmentation factor bias and allowed rate of return effects contribute in identified ways to these overall results

the economic crisis of the 1990s in finland finland s depression a tale of bad luck and bad policies in the 1990s finland underwent a deep depression as its gdp dropped about 14 and unemployment rose from 3 to almost 20 this is a story of bad luck and bad policies bad luck took the form of external shocks the collapse of trade with the former soviet union in 1991 but also sharp cycles in the oecd area however bad luck is far from being the whole story in the absence of bad policies finland would have experienced a recession not a depression bad policies included a poorly designed financial regulation and mistaken reactions to the onset of the crisis of particular interest is the role of financial factors in triggering the crisis and aggravating the effects of bad policies not only were consumption and investment spending hurt by the credit crunch but there is evidence that the private sector s indebtedness has increased structural unemployment which explains why the recovery is proceeding with few job creations a number of general lessons emerge they concern the deregulation of financial markets the policy reaction to massive capital inflows and the role of employment policies seppo honkapohja and erkki koskela

the mirage of exchange rate regimes for emerging market countries this paper argues that much of the debate on choosing an exchange rate regime misses the boat it begins by discussing the standard theory of choice between exchange rate regimes and then explores the weaknesses in this theory especially when it is applied to emerging market economies it then discusses a range of institutional traits that might predispose a country to favor either fixed or floating rates and then turns to the converse question of whether the choice of exchange rate regime may favor the development of certain desirable institutional traits the conclusion from the analysis is that the choice of exchange rate regime is likely to be of second order importance to the development of good fiscal financial and monetary institutions in producing macroeconomic success in emerging market countries this suggests that less attention should be focused on the general question whether a floating or a fixed exchange rate is preferable and more on these deeper institutional arrangements a focus on institutional reforms rather than on the exchange rate regime may encourage emerging market countries to be healthier and less prone to the crises that we have seen in recent years

market liquidity hedging and crashes in the absence of significant news hedging strategies were blamed for the stock market crash of october 1987 but traditional models cannot explain how a relatively small amount of selling could cause so large a price drop the authors develop a rational expectations model in which prices play an important role in shaping expectations markets are much less liquid in their model than in traditional models discontinuities or crashes can occur even with relatively little hedging the model is consistent with theories as disparate as keynes beauty contest insights and thom s catastrophe analysis and suggests means to reduce volatility copyright 1990 by american economic association

macroeconomic volatility trade and financial liberalization in africa this paper examines the effects of financial and trade liberalization on growth volatility of real output and consumption in africa our results suggest trade liberalization is associated with greater output and consumption growth volatility while financial liberalization increases the efficacy of consumption smoothing and stabilizes income and consumption growth in addition we find financial market depth and institutional quality operate jointly with trade and financial openness to reduce volatility in output and consumption growth there is also evidence that good institutions which foster low inflation levels and volatility promote consumption and output growth stability
