markets for pollution control when firms are noncompliant the problem of noncompliance and enforcement in transferable discharge permit tdp markets has not received much attention this paper examines the consequences of noncompliance for a tdp market given fairly general assumptions about the characteristics of the enforcement policy in place the analysis reveals that when firms are noncompliant tdp markets retain their efficiency property only under some fairly stringent conditions the effect of noncompliance on the equilibrium permit price raises some important questions about the ability of a tdp market to achieve and remain in equilibrium when firms are noncompliant

pricing risk adjusted deposit insurance an option based model this paper presents a methodology for arriving at empirical estimates of deposit insurance premiums from market data by using isomorphic relationships betweeen equity and a call option and insurance and a put option the data utilizes the market value of equity to solve for the asset value and its volatility market perceptions of fdic bailout policies are explicitly modeled so as to eliminate the bias in inverted values of assets and their volatility sensitivity analyses are performed to show that rank orderings based on premiums are robust to changes in specification thus facilitating allocation of aggregate premium across banks while economists have long argued in favor of risk adjusted deposit insurance as both more equitable and more efficient than the current system of flatrate premiums various recent developments have further contributed to an increasing dissatisfaction with the current system first both the banking industry and the government seem to be tending to the view that deregulation of the banking industry would be necessary in order to meet more sophisticated future demands on the industry as well as desirable as a policy means of stimulating greater competition among banks moreover a sudden rise in the incidence of bank failures 1 and the vulnerability of the u s banks to the socalled international debt crisis have served to bring to the fore concern about the health of the banking industry in the absence of deposit insurance riskier banks will be able to attract deposits only at higher rates and these higher costs of funding serve as built in market regulated incentives to limit excessive risk taking by banks as introduction of deposit insurance makes deposits equally risk free across banks these incentives disappear and regulation and close supervision of the banking industry must necessarily replace them as deterrents to excessive risk taking thus when insurance is offered at a flat premium regulation is designed to ensure that the risk posed to the insurer both asset and financial risk is appropriately uniform

does the european financial stability facility bail out sovereigns or banks an event study on may 9 2010 euro zone countries announced the creation of the european financial stability facility this paper investigates the impact of this announcement on bank share prices bank credit default swap cds spreads and sovereign cds spreads the main private beneficiaries were bank creditors furthermore countries with banking systems heavily exposed to southern europe and ireland benefited as evidenced by lower sovereign cds spreads the combined gains of bank debt holders and shareholders exceed the increase in the value of their banks sovereign debt exposures suggesting that banks saw their contingent claim on the financial safety net increase in value

profits from violating controls on the use of a polluting input profits from violating the quota charge and permit market systems are compared the results indicate that for a given permit price the violation profits of the charge and permit market systems are the same and exceed the profits from violating a quota system if the optimal use of inputs in a compliant market is lower than the quota it is also shown that under a permit market system the occurrence of violation decreases the equilibrium price of permits this implies that the profits from violating a permit market are lower than violation profits of a charge system

minimum information management in fisheries this paper deals with problems of optimal management of common property fisheries it advances the proposition that many fisheries management schemes which are theoretically capable of generating efficiency are actually not practicable owing to their huge informational requirements this applies for instance to management by means of corrective taxes subsidies the paper proceeds to show that there exists under fairly unrestrictive conditions market based management systems that require minimal information for their operation but lead nevertheless to efficiency in common property fisheries one such system is the individual transferable share quota system

optimal taxation without state contingent debt in an economy studied by lucas and stokey tax rates inherit the serial correlation structure of government expenditures belying barro s earlier result that taxes should be a random walk for any stochastic process of government expenditures to recover a version of barro s random walk tax smoothing outcome we modify lucas and stokey s economy to permit only risk free debt having only risk free debt confronts the ramsey planner with additional constraints on equilibrium allocations beyond one imposed by lucas and stokey s assumption of complete markets the ramsey outcome blends features of barro s model with lucas and stokey s in our model the contemporaneous effects of exogenous government expenditures on the government deficit and taxes resemble those in lucas and stokey s model but incomplete markets put a near unit root component into government debt and taxes an outcome like barro s however we show that without ad hoc limits on the government s asset holdings outcomes can diverge in importa

dueling policies why systemic risk taxation can fail abstract two policy instruments for the banking sector are investigated namely systemic risk taxation and constructive ambiguity about bailout policy bailout expectations can induce moral hazard in the form of excessive risk taking by banks systemic risk taxation induces banks to prefer uncorrelated investments leading to lower systemic risk formation constructive ambiguity generates uncertainty about bailout prospects however systemic risk taxation also may inform banks about the regulator s concern for financial stability and thereby its bailout policy this result leads to a trade off between systemic risk taxation and constructive ambiguity and highlights the need to consider interdependence across policies when evaluating their effectiveness

the incidence of interest withholding taxes evidence from the ldc loan market abstract during the 1970s developing countries differed widely in their regimes of source based interest withholding taxes this paper provides evidence on the relationship between interest rates paid by private ldc borrowers on international credits the withholding tax regime pre tax interest rates are estimated to increase significantly in withholding tax rates the extent of the mark up into higher pre tax interest rates reflects the offsetting foreign tax credits that banks expect to receive the expected tax credits represent the expected incidence of the non resident withholding taxes on creditor country treasuries estimated expected tax credits as reflected in bank interest rates vary with the year of loan origination they are relatively large for short term loans

minimum information management systems and itq fisheries management abstract in 1986 new zealand reformed its fisheries management regime with the introduction of a rights based system of management at the beginning of each fishing season a government agency sets an allowable commercial catch individual firms hold an entitlement to harvest a share of the allowable commercial catch to date the government agency has relied almost exclusively on the results of stock assessment research when setting the allowable harvest excessive reliance on biological data in fisheries management has attracted criticism an alternative a minimum information management system uses information contained in quota prices as a guide to set limits on commercial harvest this paper examines price formation in one quota market we find evidence in the data that supports the use of quota prices to guide the setting of limits to commercial harvest furthermore time series analysis provides a basis for studying the temporal response of changes in asset prices to perturbations in the allowable harvest the results illustrate how information summarized in quota prices can complement the findings of stock assessment research in fisheries management

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

determinants of commercial bank interest margins and profitability using bank level data for 80 countries in the years 1988 9s this article shows that differences in interest margins and bank profitability reflect a variety of determinants bank characteristics macroeconomic conditions explicit and implicit bank taxation deposit insurance regulation overall financial structure and underlying legal and institutional indicators a larger ratio of bank assets to gross domestic product and a lower market concentration ratio lead to lower margins and profits controlling for differences in bank activity leverage and the macroeconomic environment foreign banks have higher margins and profits than domestic banks in developing countries while the opposite holds in industrial countries also there is evidence that the corporate tax burden is fully passed onto bank customers while higher reserve requirements are not especially in developing countries

an options based approach to evaluating the risk of fannie mae and freddie mac abstract fannie mae and freddie mac assume a significant amount of interest and prepayment risk and all of the credit risk for about half of the 8 trillion u s residential mortgage market their hybrid government private status and the perception that they are too big to fail make them a potentially large but largely unaccounted for risk to the federal government measuring the size and risk of this liability is technically difficult but important for the debate over the appropriate regulation of these institutions here we take an options pricing approach to evaluating these costs and risks under the base case assumptions the estimated value of the guarantees is 7 9 billion over 10 years with a combined 5 percent value at risk of 122 billion we evaluate the sensitivity of these estimates to various modeling assumptions and also to the regulatory regime including forbearance policies and capital requirements the analysis highlights the benefits but also the challenges of taking an options based approach to evaluating the value of federal credit guarantees

bailouts the incentive to manage risk and financial crises a firm s termination leads to bankruptcy costs this may create an incentive for outside stakeholders or the firm s debtholders to bail out the firm as bankruptcy looms because of this implicit guarantee firm shareholders have an incentive to increase volatility in order to exploit the implicit protection however if they increase volatility too much they may induce the guarantee extending parties to walk away i derive the optimal risk management rule in such a framework and show that it allows high volatility choices while net worth is high however risk limits tighten abruptly when the firm s net worth declines below an endogenously determined threshold hence the model reproduces the qualitative features of existing risk management rules and can account for phenomena such as flight to quality

marketable permits market power and cheating abstract in this paper we present a model of a noncompliant firm operating in a marketable pollution permit market in the main result of the paper we show how compliance is related to the initial distribution of permits a firm with market power will cheat less the larger its endowment of permits is from a fixed stock of permits the competitive fringe however will cheat more as its endowment of permits is reduced generating an ambiguous global impact on cheating

barriers to portfolio investments in emerging stock markets the authors examine to what extent features of the international tax system and indicators of transaction costs affect the required rates of return on emerging stock markets they show that the capital gains withholding tax levied on foreign portfolio investors increases required pre tax rates of return as countries generally do not index their capital gains taxes it follows that inflation increases the capital gains tax base as well as the required rate of return on equity dividend withholding taxes instead appear not to increase the required pre tax equity returns significantly the differing results for capital gains and dividend taxes reflect the fact that foreign investors generally can receive domestic tax credits only for foreign withholding taxes paid on dividends the return on equity is part of the issuing firm s cost of capital so capital gains withholding taxes imposed on nonresidents increase the cost of capital for domestic firms and discourage physical investment private investment levels have tended to be low in developing countries in the 1980 s the cost of equity finance in developing countries has gained in importance in the last decade as these countries access to international lending capital has been limited during most of the decade what do these findings imply for the design of tax policy in relation to foreign portfolio investment in developing countries the existence of foreign tax credits for dividend taxes paid suggest that a country should tax capital gains more lightly than repatriated dividends as do greece pakistan portugal and venezuela each of these countries has positive dividend withholding taxes but no capital gains taxes imposed on non residents colombia and india do the exact opposite they tax capital gains far more heavily than dividends despite what appears optimal the trend in developing countries is toward lower dividend withholding taxes with little change in the average level of capital gains taxation it appears desirable for developing countries to index their capital gains taxes to prevent them from being higher than anticipated

short term and long term government debt and nonresident interest withholding taxes abstract this paper examines the incidence of nonresident interest withholding taxes in the international 3 month treasury bill market and the international 5 year government bond market the approach is one of pooled cross section time series regressions the evidence suggests that the yields on national treasury bills and on 5 year government bonds fully reflect the nonresident interest withholding taxes imposed on american or japanese investors nonresident interest withholding taxes on short term and long term government debt thus do not appear to be borne by the international investor

optimal taxation in the presence of bailouts the termination of a representative financial firm due to excessive leverage may lead to substantial bankruptcy costs a government in the tradition of ramsey 1927 may be inclined to provide transfers to the firm so as to prevent its liquidation and the associated deadweight costs it is shown that the optimal taxation policy to finance such transfers exhibits procyclicality and history dependence even in a complete market these results are in contrast with pre existing literature on optimal fiscal policy and are driven by the endogeneity of the transfer payments that are required to salvage the financial firm

non compliance and the quota price in an itq fishery this paper examines the effects of non compliance on quota demands and the equilibrium quota price in an itq fishery i show that whereas lower quota prices are implied unambiguously by expected penalties which are a function of the absolute violation size the expectation of penalties based upon relative violations of quota demands can under certain conditions produce higher quota prices than in a compliant quota market if there are both compliant and non compliant firms in the fishery the result would then be a shift in quota demand from compliant to non compliant firms rather than the reverse the findings are generally applicable to quota markets in other industries including pollution permit markets

the value of pension benefit guaranty corporation insurance this paper considers the cost of pension benefit guaranty corporation pbgc insurance for single employer defined benefit pension plans it derives a formula for the pbgc s liability that explicitly recognizes the two necessary conditions that must arise for the pbgc to sustain a loss first the corporation sponsoring the pension iund must undergo bankruptcy and second this pension plan must be underfunded the pbgc s liability is valued as a contingent put option and expressed as infinite series of modified bessel functions the comparative statics of the model are examined and are quite consistent with economic intuition copyright 1994 by ohio state university press

foreign tax credits the supply of foreign capital and tax exporting a numerical general equilibrium model of corporate tax reform in canada abstract this paper employs a numerical general equilibrium model to emphasize the importance of tax exporting in determining the welfare effects of tax changes in open economies tax exporting occurs through both changes in the terms of trade and changes in the net return paid to foreign owned capital results indicate that tax exporting may be as significant as efficiency in evaluating potential reforms moreover efficiency effects are strongly influenced by whether foreign capital flows are modelled as responding to the gross rental on capital or to the net rental in consideration of the role of foreign tax credits
