competition and industrial policies in a history friendly model of the evolution of the computer industry abstract in this paper we explore some problems that industrial policy faces in industries characterized by dynamic increasing returns on the basis of a history friendly model of the evolution of the computer industry how does policy affect industry structure over the course of industry evolution is the timing of the intervention important do policy interventions have indirect and perhaps unintended consequences on different markets at different times we focus on two sets of policies antitrust and interventions aiming at supporting the entry of new forms in the industry the results of our simulations show that if strong dynamic increasing returns are operative both through technological capabilities and through customer tendency to stick with a brand there is little that antitrust and entry policy could have done to avert the rise of a dominant firm in mainframes on the other hand if the customer lock in effect had been smaller either by chance or through policies that discouraged efforts of firms to lock in their customers the situation might have been somewhat different in the first place even in the absence of antitrust or entry encouraging policies market concentration would have been lower albeit a dominant firm would emerge anyhow second antitrust and entry encouraging policies would have been more effective in assuring that concentration would decrease the leading firm would continue to dominate the market but its relative power would be reduced

the impact of the eu emissions trading system on low carbon technological change the empirical evidence abstract this paper reviews the empirical literature analysing the effects of the eu emissions trading system eu ets on low carbon technological change the emerging evidence is assessed with references to both relevant economic concepts and the evolving regulation of the eu ets through the years the two most robust indications of the literature are a free allocation grandfathering tended to hamper low carbon investments in phases i 2005 2007 and ii 2008 2012 and b the eu ets appears to have been relatively more effective in stimulating innovation of low carbon technologies than their adoption importantly however a complete general picture of the impact of the eu ets on low carbon technological change is missing the main gap regards the lack of empirical evidence for phase iii 2013 2020 especially econometric studies are only few due to the lack of suitable databases accessible to researchers a problem that the relevant public authorities are urged to address thanks to the recent reforms of the eu ets the incentives for innovation and adoption of low carbon technologies are probably stronger today than ever before

monetary policy with asset backed money we study the use of asset backed money in a neoclassical growth model with illiquid capital a mechanism is delegated control of productive capital and issues claims against the revenue it earns these claims constitute a form of asset backed money the mechanism determines i the number of claims outstanding ii the dividends paid to claim holders and iii the structure of redemption fees we find that for capital rich economies the first best allocation can be implemented and price stability is optimal however for sufficiently capital poor economies achieving the first best allocation requires a strictly positive rate of inflation in general the minimum inflation necessary to implement the first best allocation is decreasing in capital wealth

pricing free bank notes abstract during the pre civil war period us banks issued distinct private monies called bank notes a bank note is a perpetual risky non interest bearing debt claim with the right to redeem on demand at par in specie this paper investigates the pricing of this private money taking into account the enormous changes in technology during the period namely the introduction and rapid diffusion of the railroad a contingent claims pricing model for bank notes is proposed and tested using monthly bank note prices for all banks in north america together with indices of the durations and costs of trips back to issuing banks constructed from pre civil war travelers guides evidence is produced that market participants properly priced the risks inherent in these securities suggesting that wildcat banking was not common because of market discipline

the innovation impact of the eu emission trading system findings of company case studies in the german power sector abstract this paper provides a detailed analysis of how the european emission trading system eu ets as the core climate policy instrument of the european union has impacted innovation towards this end we investigate the impact of the eu ets on research development and demonstration rd d adoption and organizational change in doing so we pay particular attention to the relative influences of context factors policy mix market factors and public acceptance and firm characteristics value chain position technology portfolio size and vision empirically our qualitative analysis is based on multiple case studies with 19 power generators technology providers and project developers in the german power sector which were conducted in 2008 09 we find that the innovation impact of the eu ets has remained limited so far because of the scheme s initial lack of stringency and predictability and the relatively greater importance of context factors additionally the impact varies significantly across technologies firms and innovation dimensions and is most pronounced for rd d on carbon capture technologies and organizational changes our analysis suggests that the eu ets on its own may not provide sufficient incentives for fundamental changes in corporate innovation activities at a level which ensures political long term targets can be achieved

can currency competition work abstract can competition among privately issued fiat currencies work only sometimes and partially to show this we build a model of competition among privately issued fiat currencies a purely private arrangement fails to implement an efficient allocation even though it can deliver price stability under certain technological conditions although currency competition creates problems for monetary policy it is possible to design a policy rule that uniquely implements an efficient allocation

the secular inflation term in open economy phillips curves abstract robert flood has compared three alternative specifications for the secular inflation term in an open economy phillips curve attributed respectively to buiter miller and frankel and mussa we point out 1 an arithmetic error 2 the equivalence of the frankel and mussa versions and 3 some arguments against the buiter miller version

demand pull technology push and government led incentives for non incremental technical change abstract rising expectations about future demand for new technologies increase the incentives for investments in innovation by enlarging payoffs to successful innovations how well does this notion of demand pull apply to non incremental technological change when demand is largely attributable to actions by governments in this case inventors of the most important inventions did not respond positively to strong demand pull policies filing of highly cited patents declined precipitously just as demand for wind power created a multi billion dollar market three explanations for this apparent inconsistency with the demand pull hypothesis played a role 1 the rapid convergence on a single dominant design limited the market opportunity for non incremental technical improvements 2 even though the policies implemented were stringent enough to stimulate demand uncertainty in their longevity dampened the incentives for inventions that were likely to take several years to pay off and 3 alternative explanations such as declining r d funding and weakening presidential engagement on energy appear to have been important

on the economics of private money abstract the application of laissez faire to the monetary system is a key ingredient of important proposals for monetary reform both new and old that seek to discipline government creation of money through competition this paper provides an overview of issues to be encountered in the construction of theoretical models of private monetary economies including consideration of market imperfections that have been hypothesized to arise in these systems further some descriptive history of the less regulated monetary systems of 19th century new york is undertaken with an emphasis on discussing the nature of market generated banking and monetary institutions in light of these critiques

currency competition a hayekian perspective on international monetary integration currency internationalization is examined from the vantage point of friedrich hayek s contributions in the 1970s compared with received commentaries in which only an idealized case for private money is attributed to hayek this paper underscores other dimensions of hayek s work on money and currency hayek s case for choice in currency draws on his theory of competition anticipates competition between government suppliers of fiat money accommodates many aspects of international monetary integration and embodies a distinctive approach to monetary independence choice of exchange rate regime and the transnationalization of currency hayekian predictions are outlined for future developments in currency competition

money is an experience good competition and trust in the private provision of money the interplay between competition and trust as efficiency enhancing mechanisms in the private provision of money is studied with commitment trust is automatically achieved and competition ensures efficiency without commitment competition plays no role trust does play a role but requires a bound on efficiency stationary inflation must be non negative and therefore the friedman rule cannot be achieved the quality of money can be observed only after its purchasing capacity is realized in this sense money is an experience good

competitive monies and the suffolk bank system a contractual perspective in recent years a number of monetary economists have begun to focus research on an old topic the economics of private money or free banking much of this literature is motivated by a sense that competitive markets may well prove superior to government regulation in coping with the problems inherent in a laissez faire monetary system noting this robert king in his recent survey paper suggests that the central focus of future research in this area must be the types of monetary institutions that the private market will deliver 10 123 by monetary institutions king presumably means the contractual mechanisms utilized in production and exchange relationships involving private money this paper examines one mechanism the so called suffolk bank system which the market did deliver in new england from around 1820 to just before the civil war while most historians have looked favorably on the suffolk mechanism almost all have mischaracterized the underlying rationale for the system in particular most analysts have interpreted the establishment of the suffolk bank s note redemption program as a response to gresham s law bad money drives out good money however the conditions of 19th century banking in new england and elsewhere as well prior to the establishment of the suffolk system rule out any application of gresham s law prior studies have also neglected the importance of evolutionary changes in the suffolk bank system over the first five years of its existence what we will label suffolk i was largely unsuccessful both in terms of its profitability and its capacity to control the behavior of the banks participating in the system several contract adaptations introduced in 1824 accounted for a sharp reversal in the fortunes of the suffolk bank system it is suffolk ii which has gained the accolades of bank historians ironically suffolk ii increased the prospects for a gresham s law kind of outcome of the sort emphasized by akerlof 1 however the contract structure of suffolk ii involved properties sufficient to allow that suffolk

the ban on indexed bonds 1933 77 in a recent article in this review nissan liviatan and david levhari attempt to explain the phenomenon that in spite of recent marked inflationary trends the important capital markets have not developed a significant free private enterprise market for cost of living linked bonds p 366 they note that the familiar theoretical complete dominance of indexed bonds over nonindexed bonds holds unambiguously only in an economy in which there are no nominal assets they demonstrate that borrowers may in theory insist on hedging the inflation risk on their nonindexed cash balances by issuing some nonindexed bonds at a discount that makes them attractive in spite of the risk they impose on lenders their model leads them to conclude that indexed bonds might not completely dominate nonindexed bonds however they do not claim that their model explains the phenomenon they set out to explain why is it that the free market to use their expression has come up with virtually no indexed bonds at all fortunately a simple explanation for the nonexistence of indexed bonds in the united states was provided two years

do deployment policies pick technologies by not picking applications a simulation of investment decisions in technologies with multiple applications abstract the role of deployment policies that aim to foster technological change has grown considerably especially in the fields of energy and climate however recent research has shown that the adoption of deployment policies carries the potential of locking in the technology that is most cost effective at the point of policy introduction but may be inefficient in the long term the present paper contributes to the emerging literature on the role of deployment policies in creating path dependency and eventually technology lock in while previous studies focused on the relationship between lock in and the technology specificity of deployment policies this paper introduces a new factor the existence of multiple applications for a technology we argue that this factor is highly relevant for technological lock in and should be considered by policy makers to support our argument we simulate the competition among four stationary battery technologies across energy system applications in an investment simulation model this simulation shows that the degree of competition among technologies differs strongly across applications which corresponds with a highly varying lock in probability hence selecting applications in deployment policies very likely corresponds to selecting technologies we discuss the implications of these results for both policy makers and for the academic debate on deployment policies and technological lock in as well as on technology assessment and governance more generally based on the notion that policies can have different technology specificity levels we develop the idea of the application specificity of policies and provide examples of currently enacted deployment policies that vary in terms of their technology and application specificity

information learning and the stability of fiat money abstract we analyze the stability of monetary regimes in an economy where fiat money is endogenously created by the government information about its value is imperfect and learning is decentralized we show that monetary stability depends crucially on the speed of information transmission in the economy our model generates a dynamic on the acceptability of fiat money that resembles historical accounts of the rise and eventual collapse of overissued paper money it also provides an explanation of the fact that despite its obvious advantages the widespread use of fiat money is only a recent development

innovation diversity and diffusion a self organisation model a number of features of innovation diffusion are identified appropriability diversity expectations selection learning and spillover externalities a dynamic model is formul ated to embed the diffusion question into a more general framework of disequilibrium competition the model incorporates distinct vintage structures reflecting a change in technological trajectory learning by using a nd expectations driven investment rules of thumb simulation studies reveal robust quasi logistic curves but a complicated pattern of net market share gains and losses uncertainty regarding the rationality of early or late adoption it is argued ensures that the requisite behavioral variety is present to generate these diffusion patterns copyright 1988 by royal economic society

opportunities incentives and the collective patterns of technological change in a few pages in the introductory article for this debate vernon ruttan succeeds in the unlikely task of flagging many issues at the core of the economic interpretation of technological change and by doing so he implicitly addresses also a few sensitive spots for the economic discipline at large here i will not attempt to provide any thorough view of what i consider the achievements and limitations of the current state of the art see however freeman i 994 for a critical survey which i largely share rather i shall put forward a series of remarks which hopefully could be seen as part of a much wider and still largely unexplored research programme as a premise just note that some form of attention to technology related phenomena has spread over the last 20 30 years from small enclaves of heterodox economists and economic historians to become an important concern even for quite mainstream theories of e g the firm industrial organisation macroeconomics trade growth etc from patent races all the way to new trade and new growth theories and even real business cycle macro models technical change has drawn a consideration which is less by default than it was say in robert solow s original growth models orjoe bain s barriers to entry views on industrial structures and in parallel empirical studies at the levels of specific technologies firms sectors and countries have boomed for overviews cf dosi i988 nelson i993 freeman i982 i 994 cohen i 995 and granstrand i 994 among others so at least in this sense those decreasing returns to the economics of technical change suggested by ruttan do not seem to have set in however ruttan s paper raises also substantive questions about the relative success of three interpretative perspectives which he calls induced evolutionary and path dependent in the following i shall argue that an evolutionary perspective broadly defined can easily accommodate both inducement effects and path dependent patterns of technical change let me start from what i consider the major building blocks of an

the governance of sustainable socio technical transitions a quasi evolutionary model of socio technical transitions is described in which regimes face selection pressures continuously differentiated transition contexts determine the form and direction of regime change in response to these pressures the articulation of pressures and the degree to which responses are coordinated and based on resources available within the regime define the transition context four alternative contexts are described endogenous renewal re orientation of trajectories emergent transformation and purposive transitions agency and power in the governance of regime transformation are analysed power to affect change depends on regime membership the distribution of resources for change and expectations

measuring the temporal dynamics of policy mixes an empirical analysis of renewable energy policy mixes balance and design features in nine countries abstract complex societal or environmental problems require fast and substantial socio technical transitions for instance in the case of climate change these transitions need to take place in the energy transport and several industry sectors to induce and accelerate such transitions numerous policy interventions are required which interact with each other in policy mixes while several conceptual studies on policy mixes have been published recently there is very little empirical research apart from single case or small n studies it has been prominently argued that the debate about policy mixes has reached an impasse partly due to this lack of empirical work this paper addresses this gap by providing a first analysis of the temporal dynamics of complex policy mixes to do so we develop a conceptualization and measurement of policy mix balance across instrument types as well as policy mix design features in the form of intensity as a general and technology specificity as a technology focused design feature this allows us to answer the question how temporal dynamics of policy mixes differ between countries regarding their balance and design features our measurement approach is developed bottom up i e policies are assessed individually and then aggregated systematically at the policy mix level this enables overcoming the dependent variable problem in the study of policy change i e the problem of measuring policy output more specifically we develop a comparative dataset of 522 renewable energy policies in nine oecd countries our analysis shows that countries policy mix dynamics vary strongly regarding some variables e g technology specificity but less regarding others e g balance as a validity check we also test the effects of these mix dynamics on policy outcome in the form of renewable energy technology diffusion we reflect our findings in light of the theoretical debates around policy mixes and policy design and discuss how our results provoke an agenda for the new generation of research on policy mixes we specifically discuss avenues for future research with a particular focus on the politics of policy mixes

sectoral patterns of technical change towards a taxonomy and a theory abstract the purpose of the paper is to describe and explain sectoral patterns of technical change as revealed by data on about 2000 significant innovations in britain since 1945 most technological knowledge turns out not to be information that is generally applicable and easily reproducible but specific to firms and applications cumulative in development and varied amongst sectors in source and direction innovating firms principally in electronics and chemicals are relatively big and they develop innovations over a wide range of specific product groups within their principal sector but relatively few outside firms principally in mechanical and instrument engineering are relatively small and specialised and they exist in symbiosis with large firms in scale intensive sectors like metal manufacture and vehicles who make a significant contribution to their own process technology in textile firms on the other hand most process innovations come from suppliers these characteristics and variations can be classified in a three part taxonomy based on firms 1 supplier dominated 2 production intensive 3 science based they can be explained by sources of technology requirements of users and possibilities for appropriation this explanation has implications for our understanding of the sources and directions of technical change firms diversification behaviour the dynamic relationship between technology and industrial structure and the formation of technological skills and advantages at the level of the firm the region and the country

financial futures markets and tabular standards the goal of a monetary system that provides assurance against fluctuations in purchasing power is ancient one frequently suggested and repeatedly rediscovered proposal is to attain that result by linking the currency unit to a price index that device was proposed in the nineteenth century by w stanley jevons and by alfred marshall who named it a tabular standard it has been repeatedly rediscovered in marshall s version it required no governmental action except the issuance of a price index number something which has of course become widely prevalent individuals would simply in their own interest be led to make contracts specified not in terms of the nominal number of monetary units the number of dollars but in terms of the purchasing power equivalent of the present number of monetary units that is the contract would call for paying a given number of dollars multiplied by the ratio of a price index as of that date to the date on which the contract was entered into despite the theoretical attractiveness of this idea and the absence of any effective hindrance to its adoption it has never become popular it is a particular version of the generally attractive idea of widespread indexation yet indexation has been extensive only when inflation has been extremely high and variable as in some south american countries and israel and has generally fallen into disuse when inflation has been conquered the only area in which there are any large number of indexed contracts is the area of labor contracts and even here the use of indexation is by no means dominant and tends to rise and decline as inflation rises and declines

decarbonising the power sector via technological change differing contributions from heterogeneous firms abstract in the power sector technological change is a key lever to address the decarbonisation needed to avoid dangerous climate change policy makers aim to accelerate and redirect technological change by targeting relevant firms via climate policy e g the european union emissions trading system eu ets and climate relevant technology policies e g feed in tariffs changes in firm s behaviour i e their research and development r d as well as diffusion activities are at the heart of technological change however firms are heterogeneous actors with varying attributes which perceive policy differently hence they can be expected to react very heterogeneously to these new policies based on an original dataset of 201 firms we perform a cluster analysis grouping firms along their r d and diffusion activity changes we then compare these clusters with regards to the characteristics of the contained firms our analysis results in seven clusters showing very diverse contributions to low carbon technological change suggesting potential for policy to become more effective a comparison of the firms characteristics allows us to derive indicative recommendations on how to adjust the policy mix in order to induce contributions from most firms in the power sector

status and perspectives of renewable energy policy and deployment in the european union what is needed to reach the 2020 targets abstract this article evaluates the status of current res deployment policies and barriers in the eu 27 member states and compares it to the required to meet the 2020 targets the evaluation relies strongly on the quantitative deployment status and policy effectiveness indicators european res deployment and policy has progressed strongly in recent years but the growth here has been mainly driven by effective policies in a small or medium number of top runner countries across europe the highest average policy effectiveness over six years was reached for onshore wind 4 2 biofuels 3 6 and biomass electricity 2 7 while in the heat sector all technologies score below 2 comparing the recent progress to the required growth for meeting the 2020 target it appears that some countries largely exceed the interim targets of the res directive 2009 28 ec despite this europe will need additional policy effort to reach the 2020 target critical success factors include implementing effective and efficient policies that attract sufficient investments reducing administrative and grid related barriers especially in currently less advanced countries upgrading the power grid infrastructure dismantling financial barriers in the heat sector realising sustainability standards for biomass and lowering energy demand through increased energy efficiency efforts

the implications of australia s carbon pollution reduction scheme for its national electricity market this paper assesses the major implications for the national electricity market of the introduction of a domestic cap and trade carbon pollution reduction scheme in australia the electricity sector is the largest source of emissions in the australian economy and it is this sector therefore that will bear the brunt of the impact of the proposed scheme the paper addresses core issues for the electricity market up to 2020 operating under the scheme it focuses specifically on its impact on electricity prices and generation technology mix these two variables have been assessed using a number of models each applying different assumptions about key impact factors in this paper we present a comparative summary of the results of the three highest profile models and compare their assumptions in order to explain differences in projected outcomes this comparison will give an indication of the likely range of impacts on the market of the current design of the scheme

where to draw lines stability versus efficiency what kinds of assets should financial intermediaries be permitted to hold what kinds of liabilities should they be allowed to issue should a government or a central bank offer explicit deposit insurance or implicit deposit insurance by acting as a lender of last resort this paper reviews how tensions involving stability versus efficiency and regulation versus laissez faire have for centuries run through macroeconomic analysis of these questions

endogenous supply of fiat money abstract we consider whether reputation concerns can discipline the behavior of a long lived self interested agent who has a monopoly over the provision of fiat money we obtain that when this agent can commit to a choice of money supply there is a monetary equilibrium where it never overissues we show however that monetary equilibria with no overissue do not exist when there is no commitment this happens because the incentives this agent has to maintain a reputation for providing valuable currency disappear once its reputation is high enough more generally we prove that in the absence of commitment overissue happens infinitely often in any monetary equilibrium we conclude by showing that imperfect memory can restore the positive result obtained with commitment

the suppression of state banknotes a reconsideration george selgin it is generally believed that congress in imposing a prohibitive 10 tax on state banknotes in 1865 made the public better off by doing away with inferior brands of currency while simultaneously helping finance the civil war by stimulating bond sales to national banks in truth the tax served neither purpose the true purpose of the 10 tax was not to enhance bond sales or to improve the quality of the currency but to offset the inflationary effects of greenbacks and national banknotes in the long run the public might have been better off had state banks retained their right to issue currency jel g21 n21 let us have a bank currency that will be recognized in the next town a currency that will be recognized in new york philadelphia boston new orleans chicago or any other part of the united states representative john f farnsworth illinois april 28 1864 congressional globe 38th congress 1st session 1934 i f the national banks with the great advantages which they enjoy cannot compete successfully with the state banks it simply shows that the latter subserve better the interests of the business community and should not be destroyed representative francis kernan new york february 16 1865 congressional globe 38th congress 2d session 833 i introduction during the civil war a 10 tax was placed on any issuance of notes of state chartered or incorporated banks deliberately forcing state banks out of the paper currency business and making the regulation and issuance of currency a prerogative of the federal government and of federally chartered national banks this paper reexamines the congressional decision to suppress state banknotes american monetary historians have conventionally viewed the decision as reflecting 1 the public s intolerable disgust with an unregulated currency hammond 1957 11 compare dunbar 1922 220 and 2 the government s desire to boost the demand for national bank charters so as to expand the market for its debt e g hughes and cain 1998 373 74 dowd 1992 230 i plan to argue that neither view accounts adequately for the 10 tax the first view in particular begs important questions that have gone unaddressed if state banknotes were clearly inferior to national banknotes why was a prohibitive tax needed to drive them out of circulation just how were consumers supposed to benefit from having their choices restricted i explore several responses to these questions and ultimately conclude that consumers considered some state banknotes to be just as desirable as their national bank counterparts i argue that the 10 tax served not to overcome any banknote market failure but to force the withdrawal of relatively high quality state banknotes i then proceed to show that the tax was not needed to secure adequate bond sales to national banks proponents of the tax were striving not to increase the number of applications for national bank charters but to limit growth in the aggregate money stock i conclude by suggesting that because state banks of issue could have accommodated market demands that national banks failed to satisfy consumers might have been better served had state banknotes been allowed to survive ii the chase plan when the first shots of the american civil war were fired at fort sumter the paper currency of the united states consisted of over 200 million in banknotes issued by nearly 1 500 state chartered banks the quality of these banknotes varied according to their issuers management and regulatory environment 1 some banknotes circulated at par only near their source and at fluctuating discounts elsewhere so that persons carrying notes from state to state risked incurring currency exchange losses of the sort borne by international travelers today a few were subject to especially heavy discounts or were refused altogether because their issuers solvency was in question

has government any role in money abstract recent interest in monetary reform has been sparked by the emergence of a world irredeemable paper money system in light of this interest we review the current validity of four good reasons friedman advanced in 1960 to rationalize government intervention we conclude that the forces that produced government involvement in the past will persist deregulation of financial intermediaries is desirable on grounds of market efficiency though it is an open question whether government should continue as lender of last resort we expect that the present world fiat money standard will neither degenerate into hyperinflation nor revert to a commodity standard

carbon markets and technological innovation this paper examines the effects of firm level innovation in carbon abatement technologies on optimal cap and trade schemes with and without price controls we characterize optimal cap and trade regulation with a price cap and a price floor and compare it to the special cases of pure taxation and a simple emissions cap innovation shifts the tradeoff between price and quantity based instruments towards quantitybased emissions trading schemes more specifically an increase in innovation effectiveness lowers the optimal emissions cap and leads to relaxed price controls unless the slope of the marginal environmental damage curve is small because of the decrease in the emissions cap innovation in abatement technologies can lead to a higher expected carbon price so as to provide sufficient incentives for private r d investments the expected carbon price decreases once innovative technologies are widely used

smart grids and the transformation of the electricity sector ict firms as potential catalysts for sectoral change abstract the sustainability challenges associated with increasing demand and generation of electricity require a far reaching transformation of the energy system smart grid technologies are expected to play a major role in such sectoral transformation while a growing body of literature is concerned with the dynamics and particularities of sectoral transformation most contributions have focused on exogenous shocks or new technological developments as drivers of change this paper complements the existing perspectives by exploring the role of actors as catalysts for transformation within the field of smart grid we study the transformative influence of ict firms on the energy sector in europe more specifically we analyze actor participation in 450 european smart grid projects between 2000 and 2011 as well as acquisitions in the field we find that incumbent firms from the ict sector have gained influence and drive transformation through the creation of variety in terms of technology business models and value chains as a strategic reaction electricity sector incumbents have recently acquired many start ups specialized in ict technology and thus expanded their competence base we conclude that entrants from another sector can be important catalysts for sectoral transformation and should be analyzed more systematically in transition studies

laissez faire monetary theorists in late nineteenth century america economists have recently begun to reconsider many forms of regulation of money and banks from what may be termed a laissez faire perspective some have questioned fundamentally the rationale for any government role this development raises an interesting question for historians of thought what intellectual support did the concept of a free market monetary system receive in the 19th century the heyday of classical liberalism and laissez faire thought this paper takes up the question by critically surveying american monetary writings from the last half of the 19th century 2 we find that the idea of a laissez faire monetary policy was never very popular in the united states though it did have proponents whose work was often insightful most of the relevant literature was written in response to consequences wrought by the monetary legislation of the civil war that legislation included not only the national bank acts 1863 4 but also an ancillary measure effective 1866 placing a prohibitive tax on state bank notes these laws forced banks of issue to become national banks and thus to buy federal bonds as collateral for their notes which had the intended effect of creating an extra demand for the federal government s wartime debt in addition congress authorized the issue of legal tender greenback currency by the treasury a frequent theme in the post bellum monetary literature was the alleged deficiency or inelasticity of the currency supply some the greenbackers and silverites wanted the government to increase its contributions to the money supply others especially toward the end of the century argued for the establishment of a centralized agency with special powers of note issue a handful of writers renewed the radical jacksonians campaign for laissez faire in money and banking 3 in their view the defects of existing arrangements could best be solved by deregulation of banking and by removal of the federal government from the business of supplying money

a laissez faire approach to monetary stability this paper develops some diverse hints for a new monetary system offered separately by fischer black eugene fama and robert e hall for reasons that will become evident though we should perhaps say payments system instead of monetary system none of the economists mentioned has actually proposed the particular system set forth here nor examined all its properties and we call it the bfh system not to implicate them but only to give credit for some component ideas and to have a convenient label l regardless of who if anyone may actually advocate the system contemplating it is instructive it illuminates by contrast some characteristics of our existing and recent systems

fuel mix diversification incentives in liberalized electricity markets a mean variance portfolio theory approach monte carlo simulations of gas coal and nuclear plant investment returns are used as inputs of a mean variance portfolio optimization to identify optimal base load generation portfolios for large electricity generators in liberalized electricity markets we study the impact of fuel electricity and co2 price risks and their degree of correlation on optimal plant portfolios high degrees of correlation between gas and electricity prices as observed in most european markets reduce gas plant risks and make portfolios dominated by gas plant more attractive long term power purchase contracts and or a lower cost of capital can rebalance optimal portfolios towards more diversified portfolios with larger shares of nuclear and coal plants

bank runs in the free banking period free banks in the united states issued private banknotes without discretionary restriction of entry previous research suggests explanations for noteholders relatively large losses and the substantial number of banks that closed the authors examine these hypotheses and the hypothesis that contagious runs were important the evidence provides no support for the importance of wildcat banking due to par versus market valuation of bond reserves episodic but not general support for the importance of declining bond prices and support for contagion effects and contemporaries knowledge of them with little or no impact on the number of banks that closed copyright 1994 by ohio state university press

gas generation and wind power a review of unlikely allies in the united kingdom and ireland no single solution currently exists to achieve the utopian desire of zero fossil fuel electricity generation until such time it is evident that the energy mix will contain a large variation in stochastic and intermittent sources of renewable energy such as wind power the increasing prominence of wind power in pursuit of legally binding european energy targets enables policy makers and conventional generating companies to plan for the unique challenges such a natural resource presents this drive for wind has been highly beneficial in terms of security of energy supply and reducing greenhouse gas emissions however it has created an unusual ally in natural gas this paper outlines the suitability and challenges faced by gas generating units in their utilisation as key assets for renewable energy integration and the transition to a low carbon future the single electricity market of the republic of ireland and northern ireland and the british electricity transmission trading agreement market are the backdrop to this analysis both of these energy markets have a reliance on gas generation matching the proliferation of wind power the unlikely and mostly ignored relationship between natural gas generation and wind power due to policy decisions and market forces is the necessity of gas to act as a bridging fuel this review finds gas generation to be crucially important to the continued growth of renewable energy additionally it is suggested that power market design should adequately reward the flexibility required to securely operate a power system with high penetrations of renewable energy which in most cases is provided by gas generation

whence exchange rate overshooting money stock or flow abstract money stock innovations have two principal impact effects on the exchange rate one is the direct effect as captured by the overshooting hypothesis the second is the result of the change in money growth rate expectations induced by the stock innovation simulations using a stylized monetary process verify that the front end loading of the growth rate effect is potentially much more important that the direct effect additional simulations using a calibrated monetary process demonstrate that growth rate effects are on average about twice the magnitude of stock innovation effects

interpreting new evidence about china and u s silver purchases abstract this paper offers a reinterpretation of the influence on china of america s silver policy in the early 1930 s recently compiled evidence about events in china are described and interpreted in light of a model of free banking under a commodity standard our interpretation is that the u s silver purchase program did not set off a chain of bad economic events which eventually forced china off silver and onto a fiat standard rather china was forced off silver by its own government which wanted to make itself the beneficiary of the capital gain associated with the appreciation of silver and to relieve itself of the restrictions that are imposed on government finance by a commodity standard

the characteristics of a monetary economy a keynes schumpeter approach mainstream monetary theory considers money only as an instrument meant to facilitate trading without having any effect on income or on the evolution of the economic system the aim of this paper is to elaborate a monetary theory capable of supporting the thesis of money non neutrality based on the arguments developed by keynes and schumpeter the synthesis of the theories of these two great economists will be formulated starting from the two points which are common in the views of keynes and schumpeter first in contrast with mainstream theory keynes and schumpeter state that the diffusion of a fiat money induces a radical modification into the way in which the economic system works second when keynes and schumpeter describe the reasons why money and financial aggregates are not neutral they highlight the fundamental role of the credit market and of banks in contrast with the mainstream theory they do not consider the credit market as the mirror image of the goods market

redefining innovation eco innovation research and the contribution from ecological economics while innovation processes toward sustainable development eco innovations have received increasing attention during the past years theoretical and methodological approaches to analyze these processes are poorly developed against this background the term eco innovation is introduced in this paper addressing explicitly three kinds of changes towards sustainable development technological social and institutional innovation secondly the potential contribution of neoclassical and co evolutionary approaches from environmental and innovation economics to eco innovation research is discussed three peculiarities of eco innovation are identified the double externality problem the regulatory push pull effect and the increasing importance of social and institutional innovation while the first two are widely ignored in innovation economics the third is at the least not elaborated appropriately the consideration of these peculiarities may help to overcome market failure by establishing a specific eco innovation policy and to avoid a technology bias through a broader understanding of innovation finally perspectives for a specific contribution of ecological economics to eco innovation research are drawn it is argued that methodological pluralism as established in ecological economics would be very beneficial for eco innovation research a theoretical framework integrating elements from both neoclassical and evolutionary approaches should be pursued in order to consider the complexity of factors influencing innovation decisions as well as the specific role of regulatory instruments and the experience gathered in ecological economics integrating ecological social and economic aspects of sustainable development is highly useful for opening up innovation research to social and institutional changes 2000 elsevier science b v all rights reserved

policy mixes for sustainability transitions an extended concept and framework for analysis reaching a better understanding of the policies and politics of transitions presents a main agenda item in the emerging field of sustainability transitions one important requirement for these transitions such as the move towards a decarbonized energy system is the redirection and acceleration of technological change for which policies play a key role in this regard several studies have argued for the need to combine different policy instruments in so called policy mixes however existing policy mix studies often fall short of reflecting the complexity and dynamics of actual policy mixes the underlying politics and the evaluation of their impacts in this paper we take a first step towards an extended interdisciplinary policy mix concept based on a review of the bodies of literature on innovation studies environmental economics and policy analysis the concept introduces a clear terminology and consists of the three building blocks elements policy processes and characteristics which can be delineated by several dimensions based on this we discuss its application as analytical framework for empirical studies analyzing the impact of the policy mix on technological change throughout the paper we illustrate the proposed concept by using the example of the policy mix for fostering the transition of the german energy system to renewable power generation technologies finally we derive policy implications and suggest avenues for future research

private production of scrip money in the isolated community this paper examines the appearance of one type of privately produced currency which had the generic label scrip this money appeared at widely different times and places in the united states between 1820 and 1940 in spite of federal laws prohibiting its issue the most sophistic ated and best developed example of scrip seems to have occurred in th e coal mining regions of appalachia especially in west virginia thi s experience and its implications for monetary behavior are examined here copyright 1987 by ohio state university press

beyond technology push and demand pull lessons from california s solar policy abstract the scale of the technological transformation required to reduce greenhouse gas emissions to safe levels while minimizing economic impacts necessitates an emphasis on designing climate policy to foster or at least not impede environmental innovation there is only a weak empirical base for policy makers to stand on regarding the comparative innovation effects of various climate policy options however empirical scholarship in environmental innovation is hindered by the complexity of both the innovation process and the interactions between the dual market failures of pollution and innovation that are in play and it appears that the field would benefit from the structure provided by a common lexicon this paper focuses on the issues related to policy categorization in this field these issues have received little attention in the literature despite their importance to making insights gained from empirical studies generalizable the paper reviews the origins strengths and weaknesses of the dominant policy typology of technology push versus demand pull instruments its primary contribution however is to assemble a comprehensive chronology of solar policy in california and its impacts on innovation where known and then use this as a basis for building a new policy categorization that takes advantage of the intuitive resonance of the dominant typology while encompassing the broader range of policy instruments that are employed in practice in order to stimulate environmental innovation the most noteworthy aspect of the new categorization is that it introduces a third category of environmental innovation policy instrument that focuses on improving the interface between technology suppliers and users this reflects developments in the economics of innovation literature as well as considerable evidence in the domain of distributed solar energy technologies that opportunism by some of the actors that work at this interface can be a barrier to innovation

asymmetric information and optimal bank reserves one traditional argument in favor of bank reserve requirements holds that since a b ank and its depositors are asymmetrically informed as to the bank s reserve position and its portfolio the bank will hold too few reserves and too risky a port folio this being the case presumably a central banking authority is equipped t o impose and to monitor a minimal reserve requirement yielding a pareto superior outcome this paper analyzes this position in the context of a formalmodel and shows that at least for some parameters of the model there is such a case for a minimal reserve requirement copyright 1987 by ohio state university press

the resource cost of irredeemable paper money since 1971 no major currency has a formal link to a commodity for the first time in history every currency is wholly irredeemable not as a temporary expedient but as a permanent matter monetary economists have generally treated irredeemable paper money as involving negligible real resource costs compared with a commodity currency to judge from recent experience that view is clearly false as a result of the decline in long term price predictability a key question for the future is what if any substitute for a commodity standard will emerge as a long term anchor for the price level

explaining the demand for free bank notes abstract this paper explains why the risky notes of banks established during the free banking era 1837 1863 were demanded even when relatively safe specie gold and silver coin was an alternative free bank notes were demanded because they were priced to reflect the expected value of their backing the empirical evidence supports this explanation specifically in new york wisconsin and indiana the expected value of backing was sufficient for free bank notes to circulate at par which they did in minnesota the backing for notes was very poor they exchanged well below par being treated as small denomination securities

the transition from barter to fiat money how did it become possible to exchange apparently valueless pieces of paper for goods this paper provides an equilibrium account of the transition between barter and fiat money regimes the explanation relies on the intervention of a self interested government that must be able to promise credibly to limit the issue of money to achieve credibility the government must offset the benefits of seigniorage by internalizing some of the macroeconomic externalities generated by the issue of fiat money the government s patience and the extent of its involvement in the economy are key determinants of whether the transition can be accomplished copyright 1995 by american economic association

a tale of two market failures technology and environmental policy abstract market failures associated with environmental pollution interact with market failures associated with the innovation and diffusion of new technologies these combined market failures provide a strong rationale for a portfolio of public policies that foster emissions reduction as well as the development and adoption of environmentally beneficial technology both theory and empirical evidence suggest that the rate and direction of technological advance is influenced by market and regulatory incentives and can be cost effectively harnessed through the use of economic incentive based policy in the presence of weak or nonexistent environmental policies investments in the development and diffusion of new environmentally beneficial technologies are very likely to be less than would be socially desirable positive knowledge and adoption spillovers and information problems can further weaken innovation incentives while environmental technology policy is fraught with difficulties a long term view suggests a strategy of experimenting with policy approaches and systematically evaluating their success

emissions trading and investment decisions in the power sector a case study in finland abstract organizations which consider investment in or divestment of power production licences capacity within the european community are exposed to the impacts of the european union emission allowance trading scheme eu ets in this paper the consequences of the eu ets on investment decisions are explored in a country specific setting in finland first we review the general mechanisms through which the eu ets influences size timing and cashflows of an investment next we discuss the projected changes in finnish power producers investment environment and examine the financial impacts due to the eu ets on a case investment decision a hypothetical condensing power plant 250 mwe the standard discounted cash flow dcf analysis is extended to take into account the value of two real options the option to wait and the option to alter operating scale in a quantitative investment appraisal the impact of emissions trading not only depends on the expected level of allowance prices but also on their volatility and correlation with electricity and fuel prices the case study shows that the uncertainty regarding the allocation of emission allowances is critical in a quantitative investment appraisal of fossil fuel fired power plants

the evolution of monetary policy rules abstract this article examines the evolutionary forces involved in the development of monetary policy rules over time considering in particular how these relate to proposals made by milton friedman and walter bagehot the lines between money and credit and between monetary and fiscal policy are given special focus

scottish banking before 1845 a model for laissez faire during the free banking era in eighteenth and early nineteenth century scotland there were a number of legal restrictions affecting the evolution of the system scottish banking was characterized by restrictions on small denomination and interest bearing notes there were also restrictions inhibiting the development of capital markets and entry into banking furthermore the bank of england operated as a shadow central bank for the scottish system these considerations call into question the use of the scottish banking experience as the appropriate model for laissez faire and as evidence against the legal restrictions theory of money and the new monetary economics copyright 1989 by ohio state university press
