managing without growth abstract there are three main arguments why developed countries should consider managing without growth 1 continued economic growth worldwide is not an option owing to environmental and resource constraints and so developed countries should leave room for growth in developing countries where the benefits of growth are evident 2 in developed countries growth has become uneconomic in the sense that it detracts more from well being than it adds and 3 economic growth in developed countries is neither necessary nor sufficient for meeting specific policy objectives such as full employment no poverty and protection of the environment this paper explores various growth scenarios for canada over the medium range to 2020 using lowgrow a dynamic simulation model after describing lowgrow a scenario is presented that shows conditions under which the rate of unemployment in canada could be reduced to historically low levels poverty eliminated and greenhouse gas emissions reduced to comply with canada s commitment under the kyoto protocol without relying on economic growth this is not to say that zero growth should itself become a policy objective rather that the dependence on and defence of economic growth should not be an obstacle to fulfilling more specific welfare enhancing objectives of full employment eliminating poverty and protecting the environment the paper concludes with some policy implications for managing without growth followed by an annex which provides a technical description of lowgrow

beyond carbon pricing the role of banking and monetary policy in financing the transition to a low carbon economy it is widely acknowledged that introducing a price on carbon represents a crucial precondition for filling the current gap in low carbon investment however as this paper argues carbon pricing in itself may not be sufficient this is due to the existence of market failures in the process of creation and allocation of credit that may lead commercial banks the most important source of external finance for firms not to respond as expected to price signals under certain economic conditions banks would shy away from lending to low carbon activities even in the presence of a carbon price this possibility calls for the implementation of additional policies not based on prices in particular the paper discusses the potential role of monetary policies and macroprudential financial regulation modifying the incentives and constraints that banks face when deciding their lending strategy through for instance a differentiation of reserve requirements according to the destination of lending may fruitfully expand credit creation directed towards low carbon sectors this seems to be especially feasible in emerging economies where the central banking framework usually allows for a stronger public control on credit allocation and a wider range of monetary policy instruments than the sole interest rate

endogenous growth convexity of damage and climate risk how nordhaus framework supports deep cuts in carbon emissions to slow or not to slow nordhaus 1991 was the first economic appraisal of greenhouse gas emissions abatement and founded a large literature on a topic of worldwide importance we offer our assessment of the original article and trace its legacy in particular nordhaus s later series of dice models from this work many have drawn the conclusion that an efficient global emissions abatement policy comprises modest and modestly increasing controls we use dice itself to provide an initial illustration that if the analysis is extended to take more strongly into account three essential elements of the climate problem the endogeneity of growth the convexity of damage and climate risk optimal policy comprises strong controls

stability of zero growth economics analysed with a minskyan model abstract as humanity is becoming increasingly confronted by earth s finite biophysical limits there is increasing interest in questions about the stability and equitability of a zero growth capitalist economy most notably if one maintains a positive interest rate for loans can a zero growth economy be stable this question has been explored on a few different macroeconomic models and both yes and no answers have been obtained however economies can become unstable whether or not there is ongoing underlying growth in productivity with which to sustain growth in output here we attempt for the first time to assess via a model the relative stability of growth versus no growth scenarios the model employed draws from keen s model of the minsky financial instability hypothesis the analysis focuses on dynamics as opposed to equilibrium and scenarios of growth and no growth of output gdp are obtained by tweaking a productivity growth input parameter we confirm that with or without growth there can be both stable and unstable scenarios to maintain stability firms must not change their debt levels or target debt levels too quickly further according to the model the wages share is higher for zero growth scenarios although there are more frequent substantial drops in employment

the sources of sovereign risk a calibration based on levy stochastic processes abstract governments choose to issue risky or riskless debt depending on the nature of the stochastic process of output we use brownian motion and poisson shocks a modeling method in the literature on corporate default known as levy processes to approximate a decomposition of the output process into a smooth and a jump component using an eaton and gersovitz 1981 model of debt repudiation we show that the brownian part explains the counter cyclical behavior of the current account and the poisson part explains the risk of default thus enabling our model to account for key stylized facts regarding sovereign risk

an integrated approach to climate change income distribution employment and economic growth a demand driven growth model involving capital accumulation and the dynamics of greenhouse gas ghg concentration is set up to examine macroeconomic issues raised by global warming e g effects on output and employment of rising levels of ghg offsets by mitigation relationships among energy use and labor productivity income distribution and growth the economic significance of the jevons and other paradoxes sustainable consumption and possible reductions in employment and sources of instability and cyclicality implicit in the two dimensional dynamical system the emphasis is on the combination of biophysical limits and post keynesian growth theory and the qualitative patterns of system adjustment and the dynamics that emerge

sovereign debt as a contingent claim a quantitative approach abstract we construct a dynamic equilibrium model with contingent service and adverse selection to quantitatively study sovereign debt in the model benefits of defaulting are tempered by higher future interest rates for a wide set of parameters the only equilibrium is one in which the sovereign defaults in all states additional output losses however sustain equilibria that resemble the data we show that due to the adverse selection problem some countries choose to delay default to reduce loss of reputation moreover although equilibria with no default imply greater welfare levels they are not sustainable in highly indebted and volatile countries

the effect of business risk on corporate capital structure theory and evidence under corporate and personal taxation we demonstrate that the relation between optimal debt level and business risk is roughly u shaped this result follows from the fact that the tax liability is an option portfolio that is long in the corporate tax option and short in the personal tax option therefore the net effect of a change in business risk on the optimal debt level depends upon the relative magnitudes of the resultant marginal changes in the values of these two options results of empirical tests offer support for the predicted u shaped relationship

an empirical examination of multinational corporate capital structure this paper examines whether there are systematic differences in the traditional capital structure determinants between mncs and dcs and if there are additional uniquely international factors that may help explain the capital structure choice of multinational corporations the results suggest that specific international factors such as political risk and exchange rate risk are relevant to the multinational capital structure decision that multinationals have higher agency costs than purely domestic firms and that international diversification does not lower earnings volatility for multinational corporations

investing in a green transition abstract at the rio 20 conference the world s governments affirmed a need to transition toward green economies and background reports in preparation for the event emphasized the role of investment subsequent authors noted that private investment flows overwhelm public ones arguing that private investment must be mobilized for a transition however the role of private investment in a major economic transition is poorly understood particularly when the investment is not inherently attractive to investors and must be made attractive through policy we present a model representing investment macroeconomic interactions with classical features among its novel features is a distinction between affected sectors which are sensitive to the amount of green capital in the economy because of network effects and forward backward linkages and unaffected sectors which are relatively insensitive we argue that affected sectors are both harder to change and nearer to the base of the economy in model runs we observe that in a green transition the affected sector lags the unaffected sector with possible implications for a transition strategy thus in the model firm and investor behavior postpones deeper and more systemic changes until late in the transition

ecological macroeconomic models assessing current developments our society faces a dilemma while continued economic growth is ecologically unsustainable low or negative rates of economic growth are accompanied by adverse social impacts hence there is a need for macroeconomic tools that can help identify socially sustainable post growth pathways the emerging field of ecological macroeconomics aims to address this need and features a number of new macroeconomic modelling approaches this article provides 1 a review of modelling developments in ecological macroeconomics based on the literature and interviews with researchers and 2 an analysis of how the different models incorporate policy themes from the post growth literature twenty two ecological macroeconomic models were analysed and compared to eight policy themes it was found that environmental interactions and the monetary system were treated most comprehensively themes of income inequality work patterns indicators of well being and disaggregated production were addressed with less detail while alternative business models and cross scale interactions were hardly addressed overall the combination of input output analysis with stock flow consistent modelling was identified as a promising avenue for developing macroeconomic models for a post growth economy however due to the wide interpretation of what the economy entails future research will benefit from employing a range of approaches

climate change financial stability and monetary policy using a stock flow fund ecological macroeconomic model we analyse i the effects of climate change on financial stability and ii the financial and global warming implications of a green qe programme emphasis is placed on the impact of climate change damages on the price of financial assets and the financial position of firms and banks the model is estimated and calibrated using global data and simulations are conducted for the period 2015 2115 four key results arise first by destroying the capital of firms and reducing their profitability climate change is likely to gradually deteriorate the liquidity of firms leading to a higher rate of default that could harm both the financial and the non financial corporate sector second climate change damages can lead to a portfolio reallocation that can cause a gradual decline in the price of corporate bonds third financial instability might adversely affect credit expansion and the investment in green capital with adverse feedback effects on climate change fourth the implementation of a green qe programme can reduce climate induced financial instability and restrict global warming the effectiveness of this programme depends positively on the responsiveness of green investment to changes in bond yields

multinational corporations vs domestic corporations international environmental factors and determinants of capital structure this paper examines whether or not u s based multinational corporations mncs have different capital structures than u s domestic corporations dcs and if so what causes the differences in explaining the difference between the capital structures of mncs and dcs previous studies tended to directly discuss the relationships between international environmental factors e g political risk foreign exchange risk and the capital structure a framework of analysis is proposed in this paper that examines the influence of environmental factors on the firm related capital structure determinants e g agency costs bankruptcy costs that in turn affect the capital structure of the mnc among the determinants that are examined more emphasis is placed on the discussion of agency costs since no previous studies have applied this concept in the international arena empirical tests were conducted to investigate whether mncs are significantly different from dcs regarding agency costs of debt bankruptcy costs and capital structure contrary to conventional wisdom the empirical findings show that mncs do not have lower bankruptcy costs and that they tend to have lower debt ratios than dcs

a financial macro network approach to climate policy evaluation abstract existing approaches to assess the economic impact of climate policies tend to overlook the financial sector and to focus only on direct effects of policies on the specific institutional sector they target neglecting possible feedbacks between sectors thus underestimating the overall policy effect to fill in this gap we develop a methodology based on financial networks which allows for analyzing the transmission throughout the economy of positive or negative shocks induced by the introduction of specific climate policies we apply the methodology to empirical data of the euro area to identify the feedback loops between the financial sector and the real economy both through direct and indirect chains of financial exposures across multiple financial instruments by focusing on climate policy induced shocks that affect directly either the banking sector or non financial firms we analyze the reinforcing feedback loops that could amplify the effects of shocks on the financial sector and then cascade on the real economy our analysis helps to understand the conditions for virtuous or vicious cycles to arise in the climate finance nexus and to provide a comprehensive assessment of the economic impact of climate policies

debt dilution and sovereign default risk we measure the effects of debt dilution on sovereign default risk and study debt covenants that could mitigate these effects we calibrate a baseline model with endogenous debt duration and default risk in which debt can be diluted using data from spain we find that debt dilution accounts for 78 percent of the default risk in the baseline economy and that eliminating dilution increases the optimal duration of sovereign debt by almost 2 years eliminating dilution also increases consumption volatility but still produces welfare gains the debt covenants we study could help enforcing fiscal rules

low investment and large ldc debt in the 1980s this paper aims at disentangling the correlation between ldc debt and investment in the 1980s the author shows that a large debt was not an unconditional predictor of low investment in the 1980s nor was investment abnormally low when compared to a financial autarky rate calculated in the text he does find however that the actual service of the debt crowded out investment for the rescheduling countries he shows that 1 percent of gdp paid abroad reduced domestic investment by 0 3 percent of gdp this is identical to the correlation between investment and foreign finance observed in the 1960s copyright 1993 by american economic association

consumer bankruptcy a fresh start consumer bankruptcy provides partial insurance against bad luck but by driving up interest rates makes life cycle smoothing more difficult we argue that to assess this trade off one needs a quantitative model of consumer bankruptcy with three key features life cycle component idiosyncratic earnings uncertainty and expense uncertainty exogenous negative shocks to household balance sheets we find that transitory and persistent earnings shocks have very different implications for evaluating bankruptcy rules more persistent shocks make the bankruptcy option more desirable larger transitory shocks have the opposite effect our findings suggest the current us bankruptcy system may be desirable for reasonable parameter values jel d14 d91 k35

solving the feldstein horioka puzzle with financial frictions unlike the prediction of a frictionless open economy model long term average savings and investment rates are highly correlated across countries a puzzle first identified by feldstein and horioka 1980 we quantitatively investigate the impact of two types of financial frictions on this correlation one is limited enforcement w here contracts are enforced by the threat of default penalties the other is limited spanning where the only asset available is noncontingent bonds we find that the calibrated model with both frictions produces a savings investment correlation and a volume of capital flows close to the data to solve the puzzle the limited enforcement friction needs low default penalties under which capital flows are much lower than those in the data and the limited spanning friction needs to exogenously restrict capital flows to the observed level when combined the two frictions interact to endogenously restrict capital flows and thereby solve the feldstein horioka puzzle

welfare implications of the bankruptcy reform act of 1999 abstract in recent years personal bankruptcy has become an important issue to consumers creditors and legislators alike over 40 billion dollars of unsecured debt were discharged in 1998 by 1 44 million households these losses have led legislators to propose a variety of changes in bankruptcy law the most important and recent of which is the bankruptcy reform act of 1999 ba99 i develop a dynamic stochastic general equilibrium model of personal bankruptcy to investigate the trade off between the consumption smoothing role of bankruptcy and the interest rate and deadweight costs it imposes i find that stringent means tests would reduce filing rates only slightly and would have only modest welfare consequences on the other hand the elimination of bankruptcy altogether is found to have substantial benefits this result is robust to income shock persistence and to stringency in the application of means tests

multinational corporations vs domestic corporations financial performance and characteristics the analysis in this paper is composed of two segments first the financial performance of a sample of multinational corporations mncs is compared with that derived for a control group of domestic corporations dmcs using market based performance measures then the paper presents a comparison of selected financial characteristics of the firms in the two groups the results suggest the dmcs appear to have a significantly superior risk adjusted market based performance are significantly less capitalized and have higher total risk as well as higher systematic risk the fact that mncs are substantially larger than dmcs is not found to be a significant factor in explaining the observed difference between the two groups performance

continuous time methods in finance a review and an assessment i survey and assess the development of continuous time methods in finance during the last 30 years the subperiod 1969 to 1980 saw a dizzying pace of development with seminal ideas in derivatives securities pricing term structure theory asset pricing and optimal consumption and portfolio choices during the period 1981 to 1999 the theory has been extended and modified to better explain empirical regularities in various subfields of finance this latter subperiod has seen significant progress in econometric theory computational and estimation methods to test and implement continuous time models capital market frictions and bargaining issues are being increasingly incorporated in continuous time theory the roots of modern continuous time methods in finance can be traced back to the seminal contributions of merton 1969 1971 1973b in the late 1960s and early 1970s merton 1969 pioneered the use of continuous time modeling in financial economics by formulating the intertemporal consumption and portfolio choice problem of an investor in a stochastic dynamic programming setting merton 1973b also showed how such a framework can be used to develop equilibrium asset pricing implications thereby significantly extending the asset pricing theory to richer dynamic settings and expanding the scope of applications of continuous time methods to study problems in financial economics 1 within a span of about 30 years from the publication of merton s inf luential papers continuous time methods have become an integral part of financial economics indeed in certain core areas in finance such as e g asset pricing derivatives valuation term structure theory and portfolio selection continuoustime methods have proved to be the most attractive way to conduct research and gain economic intuition the continuous time approach in these areas has produced models with a rich variety of testable implications the econometric theory for testing continuous time models has made rapid strides in the last decade and has thus kept pace with the impressive progress on the theoretical front one hopes that the actual empirical investigations and estimation using the new procedures will follow suit soon

towards post keynesian ecological macroeconomics the paper starts with a brief criticism of macroeconomic analyses of different schools of thought for their focus on economic growth and maximisation of output this applies to the traditional keynesian approach which has focused on the achievement of sufficient aggregate demand to underpin full employment and full capacity utilisation down playing aggregate supply constraints this also applies to the neoclassical approach including the current new consensus macroeconomics approach which asserts the dominant role of aggregate supply in the long run and where growth is set by the so called natural rate of growth with no concerns over environmental and ecological issues the paper then proposes a different approach to macroeconomic analysis it explicitly acknowledges that economic growth is a double edged sword growth can help to alleviate persistent levels of high unemployment but it can also lead to potentially catastrophic environmental problems building on the monetary circuit theory and the demand led growth theory the paper offers an analysis of the interconnections and interdependence of the economic biophysical and social worlds and by doing it hopes to provide the building blocks for the establishment of post keynesian ecological macroeconomics

emergence of new economics energy transition models a review abstract well known academic and non academic institutions call for a new approach in economics able to capture features of modern economies including but not limited to complexity non equilibrium and uncertainty in this paper we provide a systematic review of ecological macroeconomic models that are suitable for the investigation of low carbon energy transitions and assess them based on the features considered desirable for a new approach in economics we draw two main conclusions firstly the knowledge base and structure of these existing ecological macroeconomic models are relevant alongside other types of models for the creation of a new approach in economics secondly the reviewed models are policy relevant especially in the context of the complexity and urgency of rapid energy transitions where increasingly policymakers require economic models able to capture real world characteristics however further improvements are needed to these models and future research should focus on i assuring comparability of models results and their policy insights ii incorporation of the relationships between macroeconomics finance and sustainability and iii the institutionalization of a new approach in economics

client profitability of diffusion segments across countries for multi generational innovations the influence of firm market and cross national differences there is scant research on the important managerial question of how to maximize returns on investments in either international business or international marketing literature we propose and test a conceptual framework using data from a large technology manufacturer service provider despite early adoption by innovators and early adopters the early majority segment is most profitable however the late majority segment and the early adopters segment are the next most profitable in the developed and emerging countries respectively we propose a decision support framework incorporating cross national distances on single generation and multi generation profitability for mnes offering multi generational products in multinational markets to be more profitable

on the existence of an optimal capital structure theory and evidence one of the most contentious issues in the theory of finance during the past quarter century has been the theory of capital structure the geneses of this controversy were the seminal contributions by modigliani and miller 18 19 the general academic view by the mid 1970s although not a consensus was that the optimal capital structure involves balancing the tax advantage of debt against the present value of bankruptcy costs no sooner did this general view become prevalent in the profession than miller 16 presented a new challenge by showing that under certain conditions the tax advantage of debt financing at the firm level is exactly offset by the tax disadvantage of debt at the personal level since then there has developed a burgeoning theoretical literature attempting to reconcile miller s model with the balancing theory of optimal capital structure e g deangelo and masulis 5 kim 12 and modigliani 17 the general result of this work is that if there are significant leverage related costs such as bankruptcy costs agency costs of debt and loss of non debt tax shields and if the income from equity is untaxed then the marginal bondholder s tax rate will be less than the corporate rate and there will be a positive net tax advantage to corporate debt financing the firm s optimal capital structure will involve the trade off between the tax advantage of debt and various leverage related costs the upshot of these extensions of miller s model is the recognition that the existence of an optimal capital structure is essentially an empirical issue as to whether or not the various leverage related costs are economically significant enough to influence the costs of corporate borrowing the miller model and its theoretical extensions have inspired several timeseries studies which provide evidence on the existence of leverage related costs trczinka 28 reports that from examining differences in average yields between taxable corporate bonds and tax exempt municipal bonds one cannot reject the miller hypothesis that the marginal bondholder s tax rate is not different from the corporate tax rate however trczinka is careful to point out that this finding does not necessarily imply that there is no tax advantage of corporate debt if the personal tax rate on equity is positive indeed buser and hess 1 using a longer time series of data and more sophisticated econometric techniques estimate that the average effective personal tax rate on equity is statistically positive and is not of a trivial magnitude more importantly they document evidence that is consistent with the existence of significant leverage related costs in the economy

from ecological macroeconomics to a theory of endogenous money for a finite planet abstract this paper takes stock of the achievements and gaps of the emerging field of ecological macroeconomics which has brought insights from specific schools of macroeconomics most notably post keynesian to ecological economics with a strong emphasis on the endogeneity of money ecological macroeconomics has proposed fiscal monetary and prudential reforms to boost green investments and developed new modeling frameworks to explore the interactions between the financial macroeconomic and biophysical spheres while these proposals open a broader range of possibilities to engage in a socio ecological transition than those offered by the current paradigm of a financialized global economy they paradoxically suffer from similar limitations by placing much faith in green investments they impose a vision of the transition that presents strong technical and institutional limitations the field also fails to revisit its own understanding of macroeconomics and of specific phenomena e g financial instability through a biophysical lens in spite of increasing transdisciplinary evidence supporting this approach we suggest overcoming these limitations through institutionalist perspectives that understand money as a language through which value is created and legitimized those perspectives seem essential to re embed the governance of money within a worldview that acknowledges the finiteness and incommensurable values of earth s life support systems

the structure of economic modeling of the potential impacts of climate change grafting gross underestimation of risk onto already narrow science models scientists describe the scale of the risks from unmanaged climate change as potentially immense however the scientific models because they omit key factors that are hard to capture precisely appear to substantially underestimate these risks many economic models add further gross underassessment of risk because the assumptions built into the economic modeling on growth damages and risks come close to assuming directly that the impacts and costs will be modest and close to excluding the possibility of catastrophic outcomes a new generation of models is needed in all three of climate science impact and economics with a still stronger focus on lives and livelihoods including the risks of large scale migration and conflicts

are multinational corporations safer the failure probabilities of a sample of multinational corporations mncs are derived and compared with those of a control group of domestic corporations dmcs the results suggest that the mean insolvency probability of dmcs is significantly higher than that of the mncs it is also observed that mncs are significantly more capitalized and the standard deviation of their equity as well as their average systematic risk are also significantly lower furthermore the average insolvency probability of the dmcs is more sensitive to changes in the values of the parameters than those of the mncs

the eirin flow of funds behavioural model of green fiscal policies and green sovereign bonds abstract fiscal and monetary policies as well as new financial instruments could play a key role to meet the paris agreement however deep uncertainty characterizes their design and their potential effects on growth financial and credit market stability and inequality we develop the eirin flow of funds behavioural model to simulate the introduction of green fiscal policies and green sovereign bonds and we display their effects on firms investments in the brown and green sector on unemployment on the credit and bonds market eirin is stock flow consistent and is rooted on a balance sheet approach it adopts a leontief production function with no substitution of the production factors i e labour capital and raw materials its sectors are endowed with adaptive behaviours and expectations and interact with the others and the foreign sector through a set of markets simulations show that green public policies can promote green growth by influencing firms expectations and the credit market green sovereign bonds represent a short term win win solution while green fiscal measures have higher immediate distributive effects that induce negative feedbacks on the economy these results are influenced by the conditions fiscal budgetary and public debt gdp in which both measures are implemented

research on international business problems and prospects this paper reflects on the general problems and specific opportunities faced by contemporary research on multinational enterprise the general problems include controlling properly for the firm s opportunities when testing the effectiveness of its policy choices avoiding biases that result from studying surviving business units and ignoring those that disappeared and mobilizing longitudinal data and exploiting the many census based data sets now coming available

georgescu roegen s flow fund theory of production in retrospect abstract this paper provides a synthetic account of georgescu roegen s flow fund theory as a contribution to the history of ecological economics it reconstitutes georgescu roegen s perspective on production and its relationships with other frameworks such as the neoclassical production function and input output tables the overall purpose is to clearly establish the foundations of the flow fund theory and to introduce the research perspectives it opens for ecological economics the paper puts particular emphasis on the relationships between the flow fund framework and two other aspects of georgescu roegen s thought first his methodological perspective on economics and the role of mathematical models allows for a better understanding of the foundations of the flow fund theory second this framework incorporates georgescu roegen s interest in the physical dimension of the economic process and the implications of the laws of thermodynamics overall the paper concludes that the flow fund theory has solid foundations and thus represents a credible alternative to standard theories of production however in order to show how this framework can shed light on contemporary issues in ecological economics more applications are needed especially at the theoretical level the main challenge for future research is to develop such applications while trying to be faithful to the foundations of the flow fund theory

international corporate diversification market valuation and size adjusted evidence errunza and senbet es 7 analyze the effects of international operations on the market value of the firm both at theoretical and empirical levels the theoretical model which is largely heuristic exploits the costly supply adjustment of multinational firms mncs in providing international portfolio diversification services to investors who face differential cost barriers to direct holdings of assets across national boundaries mncs compete as financial intermediaries to undo the barriers so that in equilibrium profits are driven out mncs and pure domestic firms sell at an equivalent risk adjusted return however costly financial intermediation and the associated relative efficiency leads to a positive valuation effect for mncs relative to purely domestic firms further the equilibrium analysis implies that demand side investor barriers to international capital flows alone are inconsequential to the valuation of mncs in their pure financial role but that the interaction with the supply side costs are necessary to produce a valuation effect at the corporate level es subject the theory to an empirical analysis in a value based approach by employing a variant of tobin s 17 qratio the analysis controlling for industrial market power suggests that the relationship between the excess valuation and the degree of international involvement doi has magnified over periods characterized by severe u s government controls vis a vis the more recent periods in this paper we formalize the theoretical argument by viewing indirect portfolio diversification by mncs as a means of completing the international capital market we employ a paradigm in the unanimity literature and formally characterize the equilibrium in which there is a rationale for mnc financial intermediation we then perform an expanded empirical study by employing generalized least squares and maximum likelihood procedures since the positive relationship between excess valuation and doi as suggested in es 7 might be attributed to the so called small firm or size and the p e effects the test methodology controls for such effects also the traditional literature has relied upon foreign sales percentage as a proxy for doi in view of the well recognized limitations of this proxy we employ four different measures of international

the effects of international operations on the market value of the firm theory and evidence this paper investigates the existence of monopoly rents associated with international operations in a market value theoretic framework the benefits of international operations evolve from such factors as 1 imperfections in the product and factor markets 2 differential international taxation and 3 imperfections in the financial markets in this paper these factors are subject to an equilibrium analysis in the context of recent advances in financial theory in particular imperfections in the financial sector arising from corporate international diversification are examined in a framework which allows a supply adjustments by multinational firms and b the interaction of barriers to international capital flows faced by both firms and investors taking the u s capital market and investors as a base we then specify the conditions under which the foregoing imperfections get priced out in an equilibrium these pricing effects cannot be detected empirically through the methodologies employed by the existing studies which examine the effects of corporate international diversification indeed it was an attempt to rescue the limitations of these studies which initially motivated our paper the existing empirical inquiries into this area rely on traditional risk adjusted performance measures e g 7 or international analogs of return generating processes e g 1 8 instead at the empirical level we employ a value based method which is in the same vein of the thomadakis 17 approach developed to identify the monopoly benefits of industrial market structure we conduct the tests over subperiods characterized by differential government controls in an attempt a to separate the pure financial motives for multinationality from other motives and b to detect if the benefits of international operations carry through recent periods

coping with collapse a stock flow consistent monetary macrodynamics of global warming abstract this paper presents a macroeconomic model that combines the economic impact of climate change with the pivotal role of private debt using a stock flow consistent approach based on the lotka volterra logic we couple its nonlinear monetary dynamics of underemployment and income distribution with abatement costs a calibration of our model at the scale of the world economy enables us to simulate various planetary scenarios our findings are threefold 1 the 2 c target is already out of reach absent negative emissions 2 the long term resp short term results of climate change on economic fundamentals may lead to severe economic consequences without the implementation resp in case of too rapid an application of proactive climate policies global warming resp too fast transition forces the private sector to leverage in order to compensate for output and capital losses resp to lower carbon emissions thus endangering financial stability 3 implementing an adequate carbon price trajectory as well as increasing the wage share fostering employment and reducing private debt make it easier to avoid unintended degrowth and to reach a 2 5 c target

can degrowth overcome the leakage problem of unilateral climate policy abstract unilateral climate policy suffers from carbon leakage i e the partial offset of the initial emission reduction by increases in other countries different than most typically discussed climate policies degrowth not only aims at reducing the fossil fuel use in an economy but rather besides other social and political goals at a reduction of all factor inputs which may lead to different leakage implications we conduct the first investigation of degrowth in a multi country setting in order to i compare the leakage effects of national pure emission reduction policies to degrowth scenarios ii identify underlying channels by decomposing the implied emission changes into scale composition and technique effects and iii investigate which country characteristics determine degrowth s relative effectiveness to overcome the leakage problem using a structural gravity model we find that degrowth indeed significantly reduces leakage by keeping the sectoral composition of the country more stable and reducing uncommitted countries incentives to shift towards more energy intensive production techniques the higher effectiveness of degrowth in reducing carbon emissions is most pronounced for small and trade open economies with comparatively clean production technologies

a stock flow fund ecological macroeconomic model this paper develops a stock flow fund ecological macroeconomic model that combines the stock flow consistent approach of godley and lavoie with the flow fund model of georgescu roegen the model has the following key features first monetary and physical stocks and flows are explicitly formalised taking into account the accounting principles and the laws of thermodynamics second georgescu roegen s distinction between stock flow and fund service resources is adopted third output is demand determined but supply constraints might arise either due to environmental damages or due to the exhaustion of natural resources fourth climate change influences directly the components of aggregate demand fifth finance affects macroeconomic activity and the materialisation of investment plans that determine ecological efficiency the model is calibrated using global data simulations are conducted to investigate the trajectories of key environmental macroeconomic and financial variables under i different assumptions about the sensitivity of economic activity to the leverage ratio of firms and ii different types of green finance policies

sovereign default interest rates and political uncertainty in emerging markets abstract a large body of the empirical literature shows that high turnover rates length of tenure of policymakers and the degree of conflict within a country affects sovereign spreads debt and default rates we help to rationalize such claims by including these political features in a dynamic stochastic small open economy model of sovereign debt and default in this way we offer a complementary approach to the econometric analyses in the literature consistent with the data the quantitative analysis shows that politically unstable and more polarized economies experience higher default rates and larger level and volatility of sovereign interest rate spreads

finding common ground between ecological economics and post keynesian economics abstract post keynesian economics and ecological economics have in common that they are considered to be heterodox schools of thought aside from that there has not been a strong connection between them previous books on post keynesian economics contain no chapter on environmental or ecological issues this neglect has led leading ecological economists to criticize post keynesians for succumbing to the same growth paradigm as the neoclassical school this paper argues that the two approaches are complementary in the sense that they each have different strong points ecological economics has correctly pointed out that the growth of the global economy may not be welfare improving anymore whereas post keynesians have gained valuable insights into the functioning of the capitalist growth process to determine the feasibility of a synthesis between the two schools the paper compares their approaches to the problems of production consumption and economic dynamics as well as the associated policy recommendations it shows that on a theoretical level the two schools have much in common but their policy conclusions differ with regard to the desirability of further growth the paper concludes that a synthesis of both approaches may lead to a better understanding of how a capitalist economy operates in a natural environment with limits to growth and to better informed policy advice

faraway so close coupled climate and economic dynamics in an agent based integrated assessment model abstract in this work we develop an agent based model that offers an alternative to standard computable general equilibrium integrated assessment models iams the dystopian schumpeter meeting keynes dsk model is composed of heterogeneous firms belonging to capital good consumption good and energy sectors production and energy generation lead to greenhouse gas emissions which affect temperature dynamics climate damages are modelled at the individual level as stochastic shocks hitting workers labour productivity energy efficiency capital stock and inventories of firms in that aggregate damages emerge from the aggregation of losses suffered by heterogeneous interacting and boundedly rational agents the model is run focusing on a business as usual carbon intensive scenario consistent with a representative concentration pathway 8 5 we find that the dsk model is able to account for a wide ensemble of micro and macro empirical regularities concerning both economic and climate dynamics simulation experiments show a substantial lack of isomorphism between the effects of micro and macro level shocks as it is typical in complex system models in particular different types of shocks have heterogeneous impact on output growth unemployment rate and the likelihood of economic crises pointing to the importance of the different economic channel affected by the shock overall we report much larger climate damages than those projected by standard iams under comparable scenarios suggesting possible shifts in the growth dynamics from a self sustained pattern to stagnation and high volatility and the need of urgent policy interventions

the transition to a sustainable prosperity a stock flow consistent ecological macroeconomic model for canada abstract this paper presents a stock flow consistent sfc macroeconomic simulation model for canada we use the model to generate three very different stories about the future of the canadian economy covering the half century from 2017 to 2067 a base case scenario in which current trends and relationships are projected into the future a carbon reduction scenario in which measures are introduced specifically designed to reduce canada s carbon emissions and a sustainable prosperity scenario which incorporates additional measures to improve environmental social and financial conditions across society the performance of the economy is tracked using two composite indicators constructed especially for this study an environmental burden index ebi which describes the environmental performance of the model and a composite sustainable prosperity index spi which is based on a weighted average of seven economic social and environmental performance indicators contrary to the widely accepted view the results suggest that green growth in the carbon reduction scenario may be slower than brown growth more importantly we show in the sustainable prosperity scenario that improved environmental and social outcomes are possible even as the growth rate declines to zero

the impact of phasing out fossil fuel subsidies on the low carbon transition abstract there is growing consensus on the fact that fossil fuel subsidies provided by governments in high income countries represent a misalignment on emissions reduction with the global climate agenda in addition a discussion emerged on the negative socio economic and environmental externalities associated with fossil fuel subsidies nevertheless pathways for phasing out fossil fuel subsidies in high income countries and their implications on the low carbon transition have not yet been assessed with the aim to narrow this knowledge gap we extend the eirin stock flow consistent behavioral model to study the implications on sustainable development of the gradual phasing out of fossil fuels subsidies whose revenues could be used by the government to subsidize energy investments in green capital e g solar panels either via fiscal policies or green bonds we assess the effects on green growth employment credit and bonds market as well as the distributive effects across heterogeneous households and sectors a smooth phasing out of fossil fuels subsidies contributes to improve macroeconomic performance to decrease inequality and helps the government to find fiscal space to support stable renewable energy policies renewable energy subsidies contribute to foster the low carbon transition but could imply distributive effects depending on the way in which they are implemented

ecological macroeconomics an application to climate change ecological economics has not paid sufficient attention to the macroeconomic level both in terms of theory and modeling yet key topics debated in the field of ecological economics such as sustainable consumption reduction in working time the degrowth debate the energy exergy link and the rebound effect require a holistic and macro perspective while this deficiency has been identified before and keynesian economics has been generally suggested as a potent vehicle to establish economic system s thinking very little concrete theorizing and practical suggestions have been put forward we give further credence to this suggestion and demonstrate the value of tackling key concerns of ecological economics within a keynesian growth framework contextualized by an application to climate change we suggest that policy relevant recommendations need to be based on a consistent view of the macroeconomy we end with laying out key building blocks for a keynesian model framework for an ecological macroeconomics authors abstract

endogenous borrowing constraints with incomplete markets this article develops ways to endogenize the borrowing constraints used in a class of computable incomplete markets models we allow the constraints to depend on an investor s characteristics such as time preference risk aversion and income streams the proposed constraint can be interpreted as a borrowing limit within which an investor has no incentive to default using a numerical algorithm we find that for an array of structural parameters the endogenous borrowing constraints can be much less stringent than the ad hoc borrowing constraints adopted by the existing studies

political risk and dividend policy evidence from international political crises we examine the impact of political risk on firms payout policy using a large international sample across 35 countries over the period from 1990 to 2008 we find that global political crises raise the market perceived uncertainty and cost of external financing using crisis events as a proxy for political risk we document that past dividend payers are more likely to terminate dividends and that non payers are less likely to initiate dividends during periods of high political risk these findings suggest a precautionary incentive of managers in response to political shocks further analysis shows that the effect of political risk on payout policy is stronger for multinational corporations but can be attenuated by country specific institutional settings such as more stable political systems and stronger investor legal protection

fund flow versus flow flow in production theory reflections on georgescu roegen s contribution abstract the paper discusses nicholas georgescu roegen s contribution to production theory comparing it with the contributions of john von neumann and piero sraffa and emphasizing the problem of the choice of technique it is shown that georgescu roegen s fund flow approach in which fixed capital is taken to be an immutable agent can be misleading and cannot address issues that are easily handled by the alternative flow flow approach that reduces fixed capital to circulating within a joint products framework and allows adequate treatment of the wear and tear of machines as well as the problem of capital utilization

growth degrowth and climate change a scenario analysis article i nfo article history the paper proceeds with a discussion of the interplay of scale and intensity in determining greenhouse gas emissions this is followed by the presentation of several macroeconomic scenarios using lowgrow a simulation model of the canadian economy the scenarios considered are business as usual which is a projection into the future of past trends selective growth in which differential growth rates are applied to parts of the economy according to their direct and indirect greenhouse gas emissions and degrowth where the average gdp capita of canadians is reduced towards a level more consistent with a world economy the size of which respects global environmental limits the paper ends with a comparison of the scenarios 2011 published by elsevier b v

heterogeneous borrowers in quantitative models of sovereign default we extend the model used in recent quantitative studies of sovereign default allowing policymakers of different types to stochastically alternate in power we show that a default episode may be triggered by a change in the type of policymaker in office and that such a default is likely to occur only if there is enough political stability and if policymakers encounter poor economic conditions under high political stability political turnover enables the model to generate a weaker correlation between economic conditions and default decisions a higher and more volatile spread and lower borrowing levels after a default episode

long duration bonds and sovereign defaults abstract this paper extends the baseline framework used in recent quantitative studies of sovereign default by assuming that the government can borrow using long duration bonds this contrasts with previous studies which assume the government can borrow using bonds that mature after one quarter we show that when we assume that the government issues bonds with a duration similar to the average duration of sovereign bonds in emerging economies the model generates an interest rate that is substantially higher and more volatile than the one obtained assuming one quarter bonds this narrows the gap between the predictions of the model and the data which indicates that the introduction of long duration bonds may be a useful tool for future research about emerging economies our analysis is also relevant for the study of other credit markets

rollover risk and market freezes the debt capacity of an asset is the maximum amount that can be borrowed using the asset as collateral we model a sudden collapse in the debt capacity of good collateral we assume short term debt that must be frequently rolled over a small transaction cost of selling collateral in the event of default and a small probability of meeting a buy to hold investor we then show that a small change in the asset s fundamental value can be associated with a catastrophic drop in the debt capacity the kind of market freeze observed during the crisis of 2007 to 2008 one of the many striking features of the crisis of 2007 to 2008 was the sudden freeze in the market for the rollover of short term debt from an in stitutional perspective the inability to borrow overnight against high quality but long term assets was a market failure that effectively led to the demise of a substantial part of investment banking in the united states more broadly it led to the collapse in the united states the united kingdom and other countries of banks and other financial institutions that had relied on signifi cant maturity mismatch between assets and liabilities and in particular on the rollover of short term wholesale debt in the asset backed commercial paper abcp and overnight sale and repurchase repo markets in this paper we are interested in developing a model of a sudden collapse in the ability to borrow short term against long lived assets in the absence of obvious problems of asymmetric information or fears about the value of col lateral we refer to this phenomenon as a market freeze more precisely a market freeze occurs when the debt capacity the maximum amount of collat eralized borrowing that can be supported by an asset is a small fraction of the fundamental value the economic value measured by the net present value npv of the stream of future returns an extreme form of a market freeze occurs when the fundamental value is close to the maximum possible value of the asset whereas the debt capacity is close to the minimum possible value of the asset

green investment trends and determinants abstract this paper fills a gap in the macroeconomic literature on renewable sources of energy it offers a definition of green investment and analyzes the trends and determinants of this investment over the last decade for 35 advanced and emerging countries we use a new multi country historical dataset and find that green investment has become a key driver of the energy sector and that its rapid growth is now mostly driven by china our econometric results suggest that green investment is boosted by economic growth a sound financial system conducive to low interest rates and high fuel prices we also find that some policy interventions such as the introduction of carbon pricing schemes or feed in tariffs which require use of green energy have a positive and significant impact on green investment other interventions such as biofuel support do not appear to be associated with higher green investment

stock flow consistent macroeconomic models a survey the stock flow consistent sfc modelling approach grounded in the pioneering work of wynne godley and james tobin in the 1970s has been adopted by a growing number of researchers in macroeconomics especially after the publication of monetary economics by godley and lavoie which provided a general framework for the analysis of whole economic systems and the recognition that macroeconomic models integrating real markets with flow of funds analysis had been particularly successful in predicting the great recession of 2007 2009 we introduce the general features of the sfc approach for a closed economy showing how the core model has been extended to address issues such as financialization and income distribution we next discuss the implications of the approach for models of open economies and compare the methodologies adopted in developing sfc empirical models for whole countries we review the contributions where the sfc approach is being adopted as the macroeconomic closure of microeconomic agent based models and how the sfc approach is at the core of new research in ecological macroeconomics finally we discuss the appropriateness of the name sfc for the class of models we survey

excess market value the multinational corporation and tobin s q ratio the results of this study show that there is a positive and significant relationship between excess market value of multinational corporations and the degree of international involvement as measured by foreign sales percentage however the excess market value is not determined by the number of foreign subsidiaries nor the interaction between foreign sales and the number of foreign subsidiaries the relationship between excess market value and the two frequently used measures of monopoly power concentration ratio and the lerner index was also examined this study found that the lerner index contributes significantly in explaining excess market value but concentration ratio does not furthermore the positive and significant coefficients of advertising and r d intensity serve as evidence that product market imperfections appear to play a bigger role in explaining the excess market value experienced by mncs during our sample period

does credit create a growth imperative a quasi stationary economy with interest bearing debt abstract this paper addresses the question of whether a capitalist economy can ever sustain a stationary or non growing state or whether as often claimed capitalism has an inherent growth imperative arising from the charging of interest on debt we outline the development of a dedicated system dynamics macro economic model for describing financial assets and liabilities in a stock flow consistent framework falstaff and use this model to explore the potential for stationary state outcomes in an economy with balanced trade credit creation by banks and private equity contrary to claims in the literature we find that neither credit creation nor the charging of interest on debt creates a growth imperative in and of themselves this finding remains true even when capital adequacy and liquidity requirements are imposed on banks we test the robustness of our results in the face of random variations and one off shocks we show further that it is possible to move from a growth path towards a stationary state without either crashing the economy or dismantling the system nonetheless there remain several good reasons to support the reform of the monetary system our model also supports critiques of austerity and underlines the value of countercyclical spending by government
