legislative district configurations and fiscal policy in american states in accordance with the median voter theorem the median legislator is decisive in representative democracy if the preferences of the median legislator differ from the preferences of the median voter in the polity fiscal policy choices will predictably diverge from those favored by the median voter this paper seeks to identify the median district and therein the preferences driving the median legislator in american state legislatures using economic characteristics of constituents we find substantial differences between the median district and the statewide median as the income of the median district rises above the median income of the polity government expenditures increase in addition the degree to which income is skewed across legislative districts affects spending for redistribution programs finally we find that direct democracy procedures which allow the statewide median voter to check legislative decisions limit the impact of differences between the district and polity medians

swap rates and credit quality this article presents a model for valuing claims subject to default by both contracting parties such as swaps and forwards with counterparties of different default risk the promised cash flows of a swap are discounted by a switching discount rate that at any given state and time is equal to the discount rate of the counterparty for whom the swap is currently out of the money that is a liability the impact of credit risk asymmetry and of netting is presented through both theory and numerical examples which include interest rate and currency swaps this article presents a model for valuing claims subject to default by both contracting parties such as swaps and forwards this extends the valuation model for defaultable claims proposed by duffie and singleton 1994 to cases in which the two counterparties have asymmetric default risk the extension permits a reexamination of the impact of credit risk on swap rates while the valuation model applies to all forms of contingent claims in which both contracting parties are at risk to default such as forward contracts we focus on swaps for purposes of illustration for example consider a 5 year interest rate swap between a given party paying a floating rate such as the london inter bank offered rate libor and another counterparty paying a fixed rate replacing the given fixed rate counterparty with a lower quality counterparty whose bond yields are 100 basis points higher increases the swap rate by roughly 1 basis point using our model and typical parameters for libor rate processes this credit impact on swap rates is approximately linear within the range of normally encountered credit quality for a 5 year currency swap given a foreign exchange rate with 15 percent volatility our model shows the impact of credit risk asymmetry on the market swap rate to be roughly 10 fold greater than that for interest rate swaps that is approximately 10 basis points in swap rate per 100 basis points in bond yield credit spread the main goal of this article is to provide a simple and theoretically consistent model allowing such computations

interest rate swaps abstract using quotations from two interest rate swap dealers with different credit ratings aaa and a we examine the effect of dealers credit reputations on swap quotations and bid offer spreads the aaa offer rates are significantly higher than the a offer rates and the aaa bid rates are significantly lower than the a bid rates we also document the relation between swap rates and par bond yields estimated from london interbank offered rate libor and bid rate libid data we identify some of the problems in testing the implications of swap pricing theory

regulatory implications of credit risk modelling abstract this introduction places in context the papers on credit risk modelling contained in the special issue we explain why credit risk modelling has become such a focus of interest for practitioners and financial supervisors even though as we explain the current modelling technologies have significant weaknesses they offer the possibility of major changes in the ways banks are managed and regulated the main impediment to greater use of these models especially by regulators is the difficulty involved in back testing the risk measures they produce we suggest some thoughts on how back testing and other types of model assessment might be performed

upstream vertical integration in the aluminum and tin industries a comparative study of the choice between market and intrafirm coordination abstract this paper explores whether williamson s theory of vertical integration holds for the upstream stages of the aluminum and tin industries it concludes that the structure of these industries is broadly consistent with williamson s predictions the higher degree of upstream vertical integration in aluminum can be explained by greater scale economies higher barriers to entry higher transportation costs and greater asset specificity similarly differences in vertical integration within the tin industry can be explained in terms of the same variables

persistent demi regs and robust tendencies critical realism and the singer prebisch thesis debate about whether the terms of trade for primary products relative to manufactures have a tendency to deteriorate has been ongoing for half a century the phenomenon itself provides an example of a persistent contrastive demi regularity this is viewed as the result of a robust tendency understood as an enduring and pervasive characteristic effect generated by a powerful and stable underlying causal mechanism on this basis the key problem for primary products lies in the biological limits on consumption to which may be added capitalism specific tendencies affecting processes of production and distribution the paper concludes by arguing that the relevant holistic generic tendency under capitalism involves a long term contraction in the primary product share of world trade copyright 2002 oxford university press

government growth in the twenty first century public choice explanations of government growth fall into three main categories budget maximization theories rational choice models and path dependent models like the ratchet hypothesis the strengths and weaknesses of these theories as explanations for government growth are considered along with some facts about the actual growth of government to conjecture about its trajectory in the twenty first century government size seems to have been constrained in the past primarily by its ability to raise revenue growth rates in the new century thus appear to depend on factors constraining government s ability to continue to expand the tax base

vertical integration in the u s pulp and paper industry 1900 1940 a transaction cost model of vertical integration is tested based on detailed descriptions of every pulp and paper mill operating in the united states between 1900 and 1940 this study contributes to the literature on integration through the use of a large disaggregated database that allows identification of individual mills over time vertical integration of pulp and paper production is found to be positively associated with regional concentration paper mill capacity and production of standardized grades of paper over time new entrants behaved differently than established mills because few mills switched between integration and specialization once established copyright 1994 by mit press

the default risk of swaps we characterize the exchange of financial claims from risky swaps these transfers are among three groups shareholders debtholders and the swap counterparty from this analysis we derive equilibrium swap rates and relate them to debt market spreads we then show that equilibrium swaps in perfect markets transfer wealth from shareholders to debtholders in a simplified case we obtain closed form solutions for the value of the default risk in the swap for interest rate swaps we obtain numerical solutions for the equilibrium swap rate including default risk we compare these with equilibrium debt market default risk spreads swaps have been one of the most explosive and important innovations in international capital markets in the last 10 years in its simplest form a swap consists of an agreement hetween two entities called counterparties to exchange in the future two streams of cash flows in a currency swap these streams of cash flows consist of a stream of interest and principal payments in one cvtrrency exchanged for a stream of interest and principal payments of the same maturity in another currency in an interest rate swap they consist of streams of interest payments of one type fixed or floating exchanged for streams of interest payments of the other type in the same currency the two types of swap are shown in appendix 1 the economic importance of swap transactions is the fact that they can he comhined with deht issues to change the nature of the liahility for the borrower the sum of a hond issue and a currency swap gives a net liability stream which is equivalent to transforming the bond liability into a different currency a floating rate note combined with an interest rate swap results in a liability equivalent to fixed rate debt two issues have dominated the academic literature on swaps the first concerns the reasons for their use arbitrage of imperfections in capital markets was the original cause of their appearance price and henderson 1984 turnbull 1987 shows that lowering borrowing costs by a synthetic transaction involving a swap is not possible in a complete integrated capital market subsequent authors wall and pringle 1988 arak estrella groodman and silver 1988 smith smithson and wakeman 1987 observe

a model of political competition in the underlying space of ideology this study makes use of the concept of ideology to answerimportant questions of political competition i develop amulticandidate model in which voters use ideology as asimplifying device that helps them to choose a candidate in anoisy environment three important results arise for thehomogeneous polity case first the candidate with moreresources is the one more likely to win the election second a merger between two parties might yield to a higher expectedplurality for the candidate of the newly formed party third political convulsion yields to a decrease in the expectedplurality for the incumbent candidate

the impact of default risk on the prices of options and other derivative securities abstract this paper presents a model for valuing derivative securities when there is default risk the holder of a security is assumed to recover a proportion of its no default value in the event of a default by the counterparty both the probability of default and the size of the proportional recovery are random the paper shows how data on bonds issued by the counterparty can be used to provide information about model parameters

digitalized service multinationals and international business theory banalieva and dhanaraj argue that digital service multinationals dsmncs possess a new category of firm specific advantage fsa the network advantage and that contrary to extant theory they use networks as a mode of governance i review the business models used by dsmncs compare them to non digital ones and explore what we can learn about them from extant ib theory i conclude that network advantages are not a new category of fsas that networks are not a mode of governance and that their use by dsmncs is well explained by extant theory

political preferences for the pork barrel a generalization this paper provides a rational explanation for the observation of oversized coalitions often approaching unanimous size in the realm of distributive policies distributive policies are those which concentrate benefits in specific geographic areas states congressional districts while spreading costs through general taxation the explanation offered here that legislators may rationally prefer universalism to hard ball coalition politics generalizes earlier work of weingast and fiorina in particular it extends their results to pork barrel politics i e projects that are economically inefficient and demonstrates how packages of economically inefficient projects can nevertheless be politically popular the main theoretical feature that induces preferences for universalism is uncertainty over the composition of winning coalitions and consequently the desire for the political insurance that universalism provides

tax shares and government spending in a median voter model pear as a part of political platforms and the manipulation of tax shares through changes in progressivity loopholes writeoffs and deductions is common the purpose of this paper is to analyze the effects of including tax shares as a part of a candidate s platform within a median voter model in downs depiction of the median voter model two candidates with platforms on opposite sides of the median compete for the median voter s vote by moving their platforms toward the median if tax shares can be included in the platforms another method of competition would be to offer the me

on the difficulty of eliminating deficits with higher taxes some canadian evidence government budget deficits have increased along with government revenues from direct and indirect taxation both in absolute amounts and as a share of national income in canada as well as in several other countries especially since the 1960s this phenomenon also has coincided particularly since 1980 with skepticism over the notion that government deficit spending stimulates economic growth and employment instead many now expect deficits to produce negative effects on economic activity including high real interest rates reduced real capital formation and production increased unemployment and possible long term inflation 2 these expectations have produced a near concensus on the need to reduce government budget deficits but not on the means of achieving that goal some advocate reductions in government spending as the optimal solution while others call for increases in taxation to raise revenue although either policy in principle may achieve the same result for the deficit they arise from different theories of the determinants of government spending in particular those who advocate expenditure cuts suggest that increased taxation would increase government spending more than it would reduce the deficit arguing that there is a causal direction from increased tax revenues to increased government expenditures although the taxation spending causality hypothesis has assumed increased prominence over the last decade 3 little statistical testing has been done for canada studies by manage and marlow 18 and ram 21 lend support to the argument that expenditures are more responsive to revenues than the reverse on the basis of u s data indeed ram s work contradicts the earlier conclu

a direct test of direct democracy new england town meetings representative democracies govern most locales in the us making it difficult to compare performance relative to direct democracy new england states however provide an opportunity to test both direct and representative democracy at the local level this article uses revealed preference axioms to compare spending patterns in new england towns and cities against median voter hypothesis benchmarks contrary to previous evidence we find no differences between direct and representative democracy the results suggest that horizontal competition arising from local fragmentation minimize differences between direct and representative local government providing support for wider applicability of median voter based empirical models of local government behaviour in the us

the long run determinants of north south terms of trade and some recent empirical evidence abstract this paper reviews some recent evidence of the long run decline in the terms of trade of primary commodities versus manufactures in the context of north south trade this evidence is evaluated in the light of competing explanations of the sources of the observed long run trends in the context of a model of north south trade which includes a general resource labor and capital in the north and specific factors in a dual economy model of the south changes in factor supply sectoral and factoral bias in technical change biased demand conditions changes in the pattern of protection and institutional elements all play a role in determining the evolution of commodity and factor prices the lewis hypothesis of sectoral bias in the pattern of technical change towards temperate agriculture in the north and against tropical agriculture in the south is then reexamined in the light of the recent empirical evidence on terms of trade movements and some sketchy evidence presented on the patterns of bias in technical change in the north and the south the evidence is not consistent with an absolute technical change bias towards temperate agriculture in the north rather the rate of technical change in temperate agriculture is now comparable to that experienced in manufactures so that engel curve effects now assert the major downward pressure on the long run terms of trade between temperate agriculture commodities and manufactures overriding the effects of diminishing returns to natural resources as northern population expands the empirical evidence onbiased technical change in the south is much more sketchy and the evidence on various components of north south terms of trade is more varied

nuclear energy policy in the united states 1990 2010 a federal or state responsibility this paper examines from a policy perspective nuclear energy policy in the united states us from 1990 to 2010 and questions whether it is or has become a federal or state responsibility the present study as befits policy research engages with many disciplines for example in particular law and politics and hence the contributions move beyond that of nuclear energy policy literature and in particular to that on nuclear new build and other assessments of large infrastructure projects several examples at the federal level are identified that demonstrate that the nuclear industry has evolved to a stage where it requires a focus on the power of actions at a more localised state level in order to re ignite the industry the research concludes that there remains a misunderstanding of the issue of project management for complex construction projects and it is highly arguable whether many of its issues have been resolved further the research asserts that the economics of nuclear energy are not the most influential reason for no nuclear new build in the us

the terms of trade experience of britain since the nineteenth century the terms of trade of britain exhibited a declining trend in the first half of the nineteenth century but after two decades of transitional confusion they started to move upwards the explanation lies in the fact that the reversal of the trend corresponded to a change in the structure of british export trade from the dominance of traditional textile products towards other manufactures unlike the traditional textile products these other manufactures had little indigenous counterpart in the agrarian countries with which britain had expanding trade relations so while cost reduction through technical progress led to a rapid fall in the prices of cotton textiles under stiff competition at home and abroad producers in the newer sectors did not have to respond much to this type of cost reducing technical progress that spread to these sectors in the latter period thus as prebisch and singer argued the classical scheme of distribution of the gains from technical progress through trade that was supposed to

the imf the world bank and commodity prices a case of shifting sands abstract this paper examines some recent developments in the thinking of both the international monetary fund and the world bank regarding the macroeconomic determinants of commodity prices and the relative importance of secular and cyclical factors in explaining their recent behavior

pricing derivatives on financial securities subject to credit risk this article provides a new methodology for pricing and hedging derivative securities involving credit risk two types of credit risks are considered the first is where the asset underlying the derivative security may default the second is where the writer of the derivative security may default we apply the foreign currency analogy of jarrow and turnbull 1991 to decompose the dollar payoff from a risky security into a certain payoff and a spot exchange rate arbitrage free valuation techniques are then employed this methodology can be applied to corporate debt and over the counter derivatives such as swaps and caps the purpose of this article is to provide a new theory for pricing and hedging derivative securities involving credit risk two sources of credit risk are identified and analyzed the first is where the asset underlying the derivative security may default paying off less than promised this is the case for example with imbedded options on corporate debt the second is the credit risk introduced by the writer of the derivative security who may also default examples include over the counter writers of options on eurodollar futures swaps and swaptions for pricing derivative securities involving credit risk there are currently two approaches the first views these derivatives as contingent claims not on the financial securities themselves but as compound options on the assets underlying the financial securities this is the case for example with the pricing of imbedded options on corporate debt see merton 1974 1977 black and cox 1976 ho and singer 1982 chance 1990 and kim ramaswamy and sundaresan 1993 or the pricing of vulnerable options see johnson and stulz 1987 in practice however this valuation methodology is difficult to use first the assets underlying the financial security are often not tradeable and therefore their values are not observable this makes application of the theory and estimation of the relevant parameters problematic second as in the case of corporate debt all of the other liabilities of the firm senior to the corporate debt must first and simultaneously be valued this generates significant computational difficulties as a result this approach has not

why so much stability one of duncan black s 1958 more important contributions was a classically simple proof that with complex issues and majority voting a stable outcome is unlikely this very simple proof that there would normally be no motion which can get a majority against all others and hence that any possible outcome is dominated by another has been elaborated and made more precise by later work without most improbable conditions endless cycling would be expected this is particularly true when logrolling is present as it normally is if we look at the real world however we observe not only is there no endless cycling but acts are passed with reasonable dispatch and then remain unchanged for very long periods of time thus theory and reality seem to be not only out of contact but actually in sharp conflict it is the purpose of this article to demonstrate that our existing theory when properly looked at does indeed imply a relatively stable outcome to voting in some cases however this stability will not be a true equilibrium because a random member of a large set will be chosen and then that random outcome will be left unchanged for long periods of time it does not dominate all other outcomes but is retained merely because of its particular history there are already several possible explanations for the observed stability in the literature we will take them up as they become relevant to the general line of reasoning i should however warn the reader that my own previous work including joint work with buchanan will play a major role here this may simply reflect egotism but i think that some of the early work which is now partially forgotten can provide solutions for more modern problems much recent public choice work has involved spatial models and these models frequently ignore logrolling the reason presumably is that it is very hard to put logrolling in a two dimensional diagram we shall begin considering such special models and assume that the issues are the sort that does not lead to logrolling and then turn to more complex logrolling problems with respect to the first situation in which logrolling does not occur there is already one possible explanation for the observed stability in the literature

the application of contrast explanation to energy policy research uk nuclear energy policy 2002 2012 abstract this paper advances the application of the methodology contrast explanation to energy policy research research in energy policy is complex and often involves inter disciplinary work which traditional economic methodologies fail to capture consequently the more encompassing methodology of contrast explanation is assessed and its use in other social science disciplines explored in brief it is then applied to an energy policy research topic in this case nuclear energy policy research in the uk contrast explanation facilitates research into policy and decision making processes in energy studies and offers an alternative to the traditional economic methods used in energy research further contrast explanation is extended by the addition of contested and uncontested hypotheses analyses this research focuses on the methods employed to deliver the new nuclear programme of the uk government in order to achieve a sustainable nuclear energy policy three issues are of major importance 1 law policy and development 2 public administration and 3 project management further the research identifies that policy in the area remains to be resolved in particular at an institutional and legal level however contrary to the literature in some areas the research identifies a change of course as the uk concentrates on delivering a long term policy for the nuclear energy sector and the overall energy sector

what should government do problems of social cost externalities and all that public choice as a field introduced the framework for a methodical economic analysis of political markets the output of these markets of course is reflected by the role that government plays that is specifically true with respect to the organization of economic activity gordon tullock has studied a myriad of aspects of this topic for more than half a century we examine his answers to the question of what should government do and how they have influenced and are still impacting the discussion on the proper role of government in the economy

managing resource dependency the united states and japan in the markets for copper iron ore and bauxite abstract this study analyses the different arrangements through which the us and japan have procured their imports of non fuel minerals and attempts to shed light on the likely implications of these arrangements for the relations between these two countries it focuses on three critical minerals copper iron ore and bauxite which after oil constitute the core of every industrial society because both the us and japan exhibit high levels of dependence on foreign supplies of these three minerals it is clear that ensuring adequate supplies at reasonable costs will be a major guiding force in their respective future policies this paper examines factors affecting the international markets for these minerals the structure of investment production and trade and the relations with the source countries from the discussion of these issues two paradoxical themes emerge 1 that japan has been able to procure much of her raw materials during the 1960s and 1970s at more favourable terms than has the us even though the latter country had tighter links to its supply sources 2 that the changing conditions in the minerals industries under study have resulted in recent years in a convergence in the procurement mechanisms of the us and japan and this convergence is likely to increase strains on us japanese relations

closed form solutions for term structure derivatives with log normal interest rates we derive a unified model that gives closed form solutions for caps and floors written on interest rates as well as puts and calls written on zero coupon bonds the crucial assumption is that simple interest rates over a fixed finite period that matches the contract which we want to price are log normally distributed moreover this assumption is shown to be consistent with the heath jarrow morton model for a specific choice of volatility closed form solutions for interest rate derivatives in particular caps floors and bond options have been obtained by a number of authors for markovian term structure models with normally distributed interest rates or alternatively log normally distributed bond prices see for example jamshidian 1989 1991a heath jarrow and morton 1992 brace and musiela 1994 geman el karoui and rochet 1995 these models support black scholes type formulas most frequently used by practitioners for pricing bond options and swaptions unfortunately these models imply negative interest rates with positive probabilities and hence they are not arbitrage free in an economy with opportunities for riskless and costless storage of money briys crouhy and schobel 1991 apply the gaussian framework to derive closed form solutions for caps floors and european zero coupon bond options to exclude the influence of negative forward rates on the pricing of zero coupon bond options they introduce an additional boundary condition as shown by rady and sandmann 1994 these pricing formulas are only supported by a term structure model with an absorbing boundary for the forward rate at zero where the absorbing probability is not negligible which for a term structure model is a quite problematic assumption

learning dynamics in research alliances a panel data analysis the aim of this paper is to empirically test the determinants of research joint ventures rjvs group dynamics we develop a model based on learning and transaction cost theories which represent the benefits and costs of rjv participation respectively according to our framework firms at each period in time weigh the benefits against the costs of being an rjv member rjv dynamics can then be interpreted as a consequence of this evolving trade off over time we look at entry turbulence and exit in rjvs that have been set up under the us national cooperative research act which allows for certain antitrust exemptions in order to stimulate firms to co operate in r d accounting for unobserved project characteristics and controlling for inter rjv interactions and industry effects the tobit panel regressions show the importance of group and time features for an rjvs evolution we further identify an average rjvs long term equilibrium size and assess its determining factors ours is a first attempt to produce robust stylized facts about co operational short and long term dynamics a neglected dimension in research co operations but an important element in understanding how collaborative learning works

amend the old or address the new broad based legislation when proposing policies is costly if each legislator wishes to encourage other legislators to address new problems in future periods then a subgame perfect nash equilibrium can exist with the following properties 1 no legislator finds it worthwhile to make a narrow proposal that appeals to a minimum majority 2 instead legislators propose policies that appeal to all members not for fear of retaliation but rather to encourage other members to work on new problems in succeeding periods 3 in succeeding periods no legislator amends the existing broad policy we find an equilibrium with these properties in finite as well as infinite period games

the statistical debate on the net barter terms of trade between primary commodities and manufactures a comment and some additional evidence i950 p s hypothesis according to this hypothesis the net barter terms of trade nbtt between primary products and manufactures have over the longrun exhibited a downward trend spraos presented a detailed and thorough analysis of both the adequacy of the various statistical series available to proxy the nbtt s behaviour over the long run and the wide range of conceptual including quality problems involved in such an exercise on the basis of his analysis spraos concluded that the balance of the evidence for the seventy year period ending with the outbreak of world war ii supported the p s hypothesis of a secular deterioration in the nbtt it should however be noted that the evidence also suggested that the particular series cho sen for analysis by prebisch i950 himself did appear to exaggerate possibly to a large extent the rate of deterioration however when the analysis was extended to include the post world war ii period spraos found that while the deteriorating tendency cannot be decisively refuted it is open to doubt when the record up to the i970s is taken into account i980 p i26 as we shall see in this paper closer scrutiny reveals a statistical problem with spraos s analysis and the purpose of this paper is to show that once appropriate action is taken to overcome this problem some quite strong evidence in support of the p s hypothesis emerges the paper is organised as follows section i briefly discusses spraos s methodology and section ii discusses an econometric issue arising from this analysis section iii presents our empirical evidence while section iv summarises the main findings of the paper

default risk in a market model abstract this paper presents a theoretical model of default risk in the context of the market model approach to interest rate dynamics we propose a model for finite interval interest rates such as libor which explicitly takes into account the possibility of default through the influence of a point process with deterministic intensity we relate the defaultable interest rate to the non defaultable interest rate and to the credit risk characteristics default intensity and recovery rate we find that the spread between defaultable and non defaultable rate depends on the non defaultable rate even when the default intensity is deterministic prices of a cap on the defaultable rate and of a credit spread option are derived we consider swaps with unilateral and bilateral default risk and derive the fair fixed swap rate in both cases under the condition that both counterparties are of the same risk class we show that for a monotonously increasing term structure the swap rate for a defaultable swap will lie below the swap rate for a swap without default risk
