shadow banking and the financial side of financialisation this paper tries to shed some light on the nature and functioning of shadow banking with a special focus on its role in the evolution of financialization as well as in sharpening income and wealth inequality on the one hand it discusses how securitization has allowed traditional banks to expand their business providing the financial system with the raw materials for the manufacturing of complex structured financial products on the other hand it questions the view of traditional and shadow banks as two parallel and alternative systems claiming that financialization did not alter the role of commercial banks as money creators but rather diverted endogenously created money to the financial sphere feeding its expansion finally our work discusses some policy options for the de financialization of the economy through more progressive taxation of the financial sector as well as a stronger engagement to reduce income and wealth inequality

finance inflation and employment a post keynesian kaleckian analysis the purpose of this paper is to contribute to the post keynesian kaleckian macroeconomic literature we develop a macroeconomic model that explicitly integrates the role of borrowing and cash payment commitments on outstanding debt interest plus principal repayment into the consumption and investment expenditures as well as into the inflation generating process we explore the way that finance influences the distribution effects of inflation in the demand side of a money credit using economy we suggest a new phillips curve that encapsulates the impact of financial commitments on wage and profit claims we argue that high debt and cash payment commitments are likely to be associated with a positive demand side effect of inflation on the rate of employment and that they might be conducive to a negative supply side effect of employment on the inflation rate the author 2011 published by oxford university press on behalf of the cambridge political economy society all rights reserved

modern money theory and the facts of experience this paper discusses modern money theory mmt with a particular focus on the role of the state in its monetary system and the nature of money it addresses the main differences between the orthodox heterodox and mmt approaches to monetary theory while reconciling endogenous money theory with the state money approach by emphasising the symmetry between how banks create money as they finance private spending and how the government creates money when it finances its own spending we clarify some of the misconceptions surrounding mmt while showing that it is more consistent with the facts of experience furthermore we argue that mmt s insistence that government spending or lending must precede bond sales is consistent with the keynesian emphasis on effective demand as the driving force behind income and saving we delve into mmt s implications for monetary and fiscal policy with a particular focus on the eurozone we conclude our paper by discussing two proposals of monetary cranks narrow banking and government issue of debt free money this allows us to re emphasise mmt s views on the nature of money

the inexorable and mysterious tradeoff between inflation and unemployment this paper discusses the short run tradeoff between inflation and unemployment although this tradeoff remains a necessary building block of business cycle theory economists have yet to provide a completely satisfactory explanation for it according to the consensus view among central bankers and monetary economists a contractionary monetary shock raises unemployment at least temporarily and leads to a delayed and gradual fall in inflation standard dynamic models of price adjustment however cannot explain this pattern of responses reconciling the consensus view about the effects of monetary policy with models of price adjustment remains an outstanding puzzle for business cycle theorists several years ago i gave myself a peculiar assignment i decided to try to summarise all of economics in ten simply stated principles the purpose of this task was to introduce students to the economic way of thinking in the first chapter of my textbook principles of economics i figured if god could boil all of moral philosophy down to ten commandments i should be able to do much the same with economic science most of the ten principles i chose were microeconomic and hard to argue with they involved the importance of tradeoffs marginal analysis the benefits of trade market efficiency market failure and so on i allocated the last three principles to macroeconomics the first of these was a country s standard of living depends on its ability to produce goods and services which i viewed as the foundation of all growth theory the second was prices rise when the government prints too much money which i took to be the essence of classical monetary theory the last of my ten principles is the subject of today s lecture society faces a short run tradeoff between inflation and unemployment perhaps not surprisingly this statement turned out to be controversial when my publisher sent out the manuscript for review a few readers objected

money creation under full reserve banking a stock flow consistent model this paper presents a stock flow consistent model of full reserve banking it is found that in a steady state full reserve banking can accommodate a zero growth economy and provide both full employment and zero inflation furthermore a money creation experiment is conducted with the model an increase in central bank reserves translates into a two thirds increase in demand deposits money creation through government spending leads to a temporary increase in real gdp and inflation surprisingly it also leads to a permanent reduction in consolidated government debt the claims that full reserve banking would precipitate a credit crunch or excessively volatile interest rates are found to be baseless

a critical reconsideration of the foundations of monetary policy in the new consensus macroeconomics framework monetary policy has become firmly based on the use of interest rate as the key policy instrument and in a one instrument one target framework the approach to monetary policy is closely associated with the new consensus in macroeconomics ncm this paper undertakes a critical appraisal of the role of monetary policy in the context of the ncm after setting out the main features of the ncm there is critical discussion of the role of monetary policy and the ncm framework the discussion covers the nature of the loss function the role of the natural rate of interest and the phillips curve this is followed by a critical evaluation of the is curve in the ncm and the classical dichotomy the paper finishes by asking whether interest rates do have the effects claimed for them

stakeholder interviews with two mavt preference elicitation philosophies in a swiss water infrastructure decision aggregation using swing weighting and disaggregation using uta gms abstract we used two types of preference elicitation methods based on multi attribute value theory mavt for a wastewater infrastructure decision in switzerland we aimed to register the implementation impacts of two preference elicitation philosophies aggregation disaggregation in a large real world case and give guidance on these elicitation approaches for practitioners we conducted two series of face to face interviews with the same ten the first interview set used direct aggregation preference elicitation methods which decomposed an additive value model into the elicitation of weights smart swing variant and marginal value functions bi section method in the second interview series indirect disaggregation was used based on uta gms the weights and marginal value functions for 19 objectives were later simultaneously inferred with linear programming from pairwise comparisons of hypothetical alternatives one aim was to design the uta gms comparisons for many objectives further we aimed to identify differences and commonalities of the two methods concerning the elicited preferences the mavt evaluation results of six real world wastewater infrastructure alternatives and the stakeholders and analysts feedbacks similar best alternatives indicate convergence of the two elicitation methods this demonstrates the applicability of the uta gms elicitation procedure to a very complex decision problem however the two elicitation methods were perceived differently by the respondents and required different effort from the analysts for individual stakeholders preferences were sometimes rather different between the interviews which could be largely explained by the constructive nature of preference formation this indicates the importance of supporting stakeholder learning in the application of mcda

modeling a multi attribute utility newsvendor with partial backlogging abstract traditional newsvendor models usually focus on single profit maximization or cost minimization approaches however making a monetary estimate of the consequences of lost sales as a result of shortages is often a difficult task for many practitioners besides there is still a lack of an explicit account of decision making judgments on the multiple consequences of making decisions with regard to order quantities in order to deal with this problem this paper presents a multi attribute utility model for the newsvendor problem with regard to profit the impacts of service level on corporate image and on customers goodwill and the impact on the environment arising from the disposal of unsold products demand is partially backlogged according to a decreasing exponential function of the waiting time the fundamental principles and limitations related to the application of the model built are also discussed

speculative bubbles in bitcoin markets an empirical investigation into the fundamental value of bitcoin amid its rapidly increasing usage and immense public interest the subject of bitcoin has raised profound economic and societal issues in this paper we undertake economic and econometric modelling of bitcoin prices as with many asset classes we show that bitcoin exhibits speculative bubbles further we find empirical evidence that the fundamental price of bitcoin is zero

preference disaggregation 20 years of mcda experience abstract the philosophy of preference disaggregation in multicriteria decision aid systems mcda is to assess infer global preference models from the given preferential structures and to address decision aiding activities this paper presents a panorama of preference disaggregation methods and summarises the most important results and applications over the last 20 years

necessity as the mother of invention monetary policy after the crisis we examine recent changes in monetary policy due to the financial crisis and ask whether they are likely to be temporary or permanent we present evidence from two original surveys one of central bank governors the other of academic specialists we find that central banks in crisis countries are more likely to have resorted to new policies to have had discussions about changing mandates and to have communicated more extensively but thinking has changed more broadly for instance many central banks in non crisis countries also report implementing macro prudential measures looking forward we expect central banks to have broader mandates use macro prudential tools more widely and communicate more actively than before the crisis while there is no consensus yet about the usefulness of unconventional monetary policies we expect most of them will remain in central banks toolkits as governors who gain experience with a particular tool are more likely to assess that tool positively finally the relationship between central banks and their governments might well have changed with central banks crossing the line into the political realm more often than in the past

horizontalism a critique this article offers a critique of the horizontalist view of money that banks are passive in the face of credit demand it is argued that banks liquidity preference influences their responsiveness to the demand for credit their liquidity preference is expressed in risk assessment understood in terms of john maynard keynes s theory of uncertainty it is argued that rationing in the sense of adverse changes in risk assessment occurs systematically in the downturn of the business cycle systematic rationing also occurs with respect to particular classes of borrowers the focus here is on the case of small firms c 1996 academic press limited copyright 1996 by oxford university press

100 percent reserve banking a critical review of green perspectives abstract 100 percent reserve banking c perb is an enduring proposal for monetary reform that has been taken up by some ecological economists this paper identifies three groups of green arguments in favor of c perb and offers some criticism first the proposal could serve to constrain new investments by the availability of savings thereby checking economic growth however this would strongly increase interest rate volatility second it could potentially elevate environmental considerations in decisions about resource allocation by increasing the role of the democratic state as an economic actor this line of argument faces problems that require further detailed exploration and historical perspective third a transition to c perb would allow debt levels to be drastically cut this is technically possible but politically a tall order whether the existing system of debt based bank money generates a significant growth imperative is unclear and the importance of other driving forces behind perennial economic growth in modern societies which c perb does not address remains an issue of contention in general the adoption of c perb presupposes a tremendous reconfiguration of power relations between states and finance capital

conflict dissolution in the public sector a case study abstract the construction of a new railway link to the port of lisbon has been postponed many times as a result of a conflict of different viewpoints held by various public stakeholders namely between the municipality of lisbon and the lisbon railway node bureau while the portuguese railway company has assumed a more flexible attitude over recent years three groups of solutions totalling nine alternative projects have been proposed by each of these three actors but none has been simultaneously accepted by all the three the development of the urbanisation plan for alc ntara the zone of the city where the railway line links to the port has presented an opportunity to try to dissolve the conflict this paper describes the multicriteria approach followed to support the creation of a new good win win compromise solution by the planning team based on the study of the consequences of the existing alternatives in particular we describe the structuring phase of the study and the use of a disaggregation aggregation approach to take into account the different value systems of the stakeholders

solvency rule versus taylor rule an alternative interpretation of the relation between monetary policy and the economic crisis one of the more debated interpretations of the economic crisis that started in 2007 08 is based on the taylor rule equation namely the idea that over the period 2002 05 the fed has implemented a low interest policy that has led to the housing bubble and finally to the great recession this paper shows that the taylor rule equation not only rests on the so called new consensus macroeconomics but also on the neoclassical theory of growth the various criticisms raised against these theoretical foundations suggest that interpretations of the great recession based on the taylor rule equation are building their arguments on shaky theoretical premises furthermore this paper shows that an equation formally similar but logically alternative to the taylor rule can be regarded as the expression of a general condition of solvency of firms and workers according to this solvency rule the prevailing outcome of monetary policy decisions is the regulation of insolvencies

money moral authority and the politics of creditworthiness this article moves beyond current controversies on the nature of money by suggesting that a general social process allows different kinds of organizations and networks from states to banks to local communities to produce currencies that is the articulation of criteria of creditworthiness or what i call the exercise of moral authority bankers specialize in moral authority but when that authority is contested challenging groups must articulate alternative criteria of creditworthiness for their currencies to become stable and acceptable i illustrate these processes with historical material from the postbellum united states which i use to discuss why the federal government failed to create a stable financial system and why local bankers engaged in a process of financial innovation that further destabilized money i conclude with reflections on the shifting structural sources of moral authority which have made the local level a springboard for destabilizing financial innovations

sine praejudicio economics and the 2014 scottish independence referendum the purpose of this paper is to analyse the contribution of expert economic opinion to the 2014 referendum campaigns on scottish independence we argue that the input from economics to both sides of the debate as well as to independent analysis was constrained by a mainstream economics framing the result was a focus on calculable outcomes predicated on unchanging institutions and behaviour and the question of currency arrangements that assumes the status quo is an optimal currency area as the consequences of constitutional change for institutions and behaviour are uncertain an equilibrium framework treats anything beyond calculable prediction as a shock inducing fear of the unknown in contrast a political economy approach is tailored to analysing uncertain developments and encompassing the broader issues relating to values democracy and power and is thus better suited to the analysis of constitutional change

the ontology of money tony lawson s recent foray into social ontology in this journal takes as its subject money this essay examines lawson s ontological analysis of money with a view to clarifying the compatibility between his ontological position and credit theories of money especially those which stand in the chartalist tradition it also examines lawson s claims about commodity theories of money in light of credit theorists pronunciations on commodity theories

the modern view of macroeconomics some critical reflections david romer has proposed a new basic macroeconomic framework the is mp ia model its proponents claim that it represents the modern view of macroeconomics we show that the new framework remains closely attached to the neoclassical synthesis and in addition does not take account of i the empirical evidence on the output inflation trade off ii the evidence on the interdependence of aggregate demand and supply iii the institutional limits of monetary policy and iv the implications for macroeconomic policy of i ii and iii once these aspects have been incorporated short run stabilisation policy is not neutral in the long run the notion of a natural rate of interest becomes untenable and aggregate demand turns into the crucial exogenous variable copyright 2005 oxford university press

corporate finance side of the q theory of investment abstract this paper presents a model of a firm under uncertainty in which the financial and investment decisions are simultaneously determined if profits are small relative to investment the firm finances a constant fraction of incremental investment by debt and the rest by retentions if profits are large relative to investment a constant fraction of marginal finance comes from debt and the rest from new shares in these two financing regimes a one to one relationship between optimal investment and q can be derived no such relation exists in the third and intermediate regime in which incremental investment is entirely debt financed

full reserve banking more cranks than brave heretics this paper analyses the main features and policy implications of full reserve banking frb proposals it argues that whilst frb advocates recognize the essential endogeneity of the money creation process they have failed to understand the post keynesian and monetary circuitist analyses of endogenous money which leads them to analytical errors including lending activity creates seigniorage privilege for commercial banks inflation is always and everywhere a monetary phenomenon the inability of distinguishing the actual from the planned supply of bank loans and money to be spent from money hoarded and the debt free money proposition the paper also argues that an frb system is likely to exacerbate financial instability for several reasons including the obsessive focus on commercial banks while ignoring non bank financial intermediaries and shadow banking a blind fascination for the safety and security of the payment system with little consideration for the financing needs of capitalist economies and an inherent deflationary bias furthermore frb arrangements would soon be undermined by the development of alternative near moneys finally frb will nullify the automatic stabilisers of fiscal policy and lead to a de facto dominance of monetary policy and unelected central bankers over fiscal policy and democratic decision making

unemployment wage bargaining and capital labour substitution many economists believe that capital accumulation technical progress and labour force expansion have no lasting effect on unemployment this view rests on the empirically doubtful assumption that the elasticity of substitution between labour and capital is equal to unity i e production is cobb douglas using a simple model based on the work of layard nickell and jackman this paper demonstrates that with a lower elasticity of substitution the equilibrium unemployment rate is affected by all of the above factors it considers briefly how capital accumulation may be endogenised and what long run implications this has for unemployment copyright 1999 by oxford university press

implausible alternatives in eliciting multi attribute value functions abstract many methods to elicit preference models in multi attribute decision making rely on evaluations of a set of sample alternatives by decision makers using orthogonal design methods to create this set of alternatives might require respondents to evaluate unrealistic alternatives in this paper we perform an empirical study to analyze whether the presence of such implausible alternatives has an effect on the quality of utility elicitation using a new approach to measure consistency we find that implausible alternatives in fact have a positive effect on consistency of intra attribute preference information and consistency with dominance but do not affect inter attribute preference information

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

agricultural product development using multidimensional and multicriteria analyses the case of wine abstract multicriteria analysis and multidimensional statistical methods can collaborate and offer new prospects in the fields of decision support and management in general this paper presents a survey based methodology which combines a multicriteria model for the consumer s preference analysis as well as classical data analysis models to design agricultural products the new products are developed in such a way that they eventually achieve the maximum possible market share a real study for the athenian wine market is presented for illustration the paper concludes with some further reccomendations

application of the modified tobin s q to an uncertain energy saving project with the real options concept abstract this paper is to develop a modified tobin s q evaluation method which successfully combines the evaluation criteria of the traditional tobin s q and the real options this study provides flexible thinking for decision making criteria that is it clearly provides decision makers with a reference in choosing enter or exit strategies such as quantitative indicators references the proposed model introduces two variables stochastic process in continuous time and explores the impact of the occurrence of unexpected events on the project value so that it can more authentically response to the project value the studied issue deals with the firms that have not established energy saving equipment yet it attempts to figure out the optimal timing to adopt an energy saving investment project when it is beneficial and the optimal timing to terminate it when the continuous operation of that business is unprofitable the future discounted benefit cost ratio q follows the geometric brownian motion with the poisson jump process and the replacement of investment equipment except for the evaluation of energy saving equipment investment project the proposed model can be applied to other related project evaluation issues such as energy saving co 2 emission reduction or general investment projects

retrospectives the lost art of economics economists generally divide economics into two distinct categories positive and normative but how applied economics fits within these categories is unclear this paper argues that applied economics belongs in neither normative nor positive economics instead it belongs in a third category the art of economics currently many economists are trying to use a methodology appropriate for positive economics to guide their applied work work that properly belongs in the art of economics this three part distinction is not mine but dates back to a classic book the scope and method of political economy 1891 by john neville keynes in his book keynes argued that economists failure to distinguish the art of economics as a separate branch from positive and normative economics would lead to serious problems one hundred years later he has turned out to be clairvoyant

a stochastic frontier analysis of financing constraints on investment is shown that investment under financing constraints can be modeled as a one sided deviation from a frictionless investment level and that effects of financing constraints can be identified and quantified by imposing a distributional assumption on the effects panel data on taiwanese manufacturing firms between 1989 and 1996 are used in the estimation it is found that 1 some of the sorting criteria used in the literature do not have significant and monotonic relationships with the degrees of financing constraint resulting in problematic sample separations and 2 the effects of financial liberalization in taiwan are such that the investment efficiency improved over time for a typical firm and the improvement was particularly large for smaller firms

the quest for prosperity without inflation abstract in recent years activist monetary policy rules responding to inflation and the level of economic activity have been advanced as a means of achieving effective output stabilization without inflation advocates of such policies suggest that their flexibility may yield substantial stabilization benefits while avoiding the excesses of overzealous discretionary fine tuning such as is thought to characterize the experience of the 1960s and 1970s in this study i present evidence suggesting that these conclusions are misguided using an estimated model i show that when informational limitations are properly accounted for activist policies would not have averted the great inflation but instead would have resulted in worse macroeconomic performance than the actual historical experience the problem can be attributed in large part to the counterproductive reliance of these policies on the output gap the analysis suggests that the dismal economic outcomes of the great inflation may have resulted from an unfortunate pursuit of activist policies in the face of bad measurement specifically overoptimistic assessments of the output gap associated with the productivity slowdown of the late 1960s and early 1970s

corporate failure prediction in the european energy sector a multicriteria approach and the effect of country characteristics this study examines the development of corporate failure prediction models for european firms in the energy sector using a large dataset from 18 countries the construction of the models is based on a multiple criteria decision aid mcda approach taking into account both ordinal criteria and nominal country sector effects the analysis is based on different modeling specifications first traditional financial variables are examined which are then extended with additional country level data related to the economic and business environment as well as data about the energy efficiency policies of the countries and the characteristics of their energy markets and networks the results indicate that energy related attributes have high discriminating power and add valuable information compared to the other attributes

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

a response to critiques of full reserve banking in this response to critiques of full reserve banking or sovereign money proposals we challenge four of the main criticisms made by fontana and sawyer this issue i the impact of the proposal on government finances and fiscal policy ii the impact of the proposal on the supply of credit to the real economy iii the danger of private money creation re emerging in the shadow banking sector and iv the argument that shadow banking not commercial banking is the real source of financial instability

the role of the state and the hierarchy of money this paper uses minsky s definition of money as a two sided balance sheet phenomenon to challenge many common positions on the nature evolution and role of money his definition is applied to two opposing theories in the history of monetary debates and it is shown that the chartalists as opposed to the metallists developed a general theory of money that can be applied equally convincingly to the entire era of state money this theory is then used to show that the state s power to make and enforce tax laws renders its money the most acceptable form of debt within what can be considered a hierarchy of monies this leads to some important policy implications as well as a strengthening of the endogenous money position copyright 2001 by oxford university press

social positioning and the nature of money the question of the nature of money is pursued drawing on results generated in the field of social ontology as well as on observations from history the conception of the nature of money found in this manner to be the most sustainable is compared to various other prominent if usually held to be mutually incompatible theories

aggregate demand conflict and capacity in the inflationary process this paper focuses on an alternative perspective on inflation to that of the non accelerating inflation rate of unemployment nairu it indicates that there are no automatic forces leading to a level of aggregate demand consistent with constant inflation inflationary pressures arise from conflict over income shares and from cost elements with the price of raw materials especially oil being the most important there are supply side factors impinging on the inflationary process which arise from the level of productive capacity relative to aggregate demand the supply side constraints are viewed as arising from capacity constraints rather than from the operation of the labour market copyright 2005 oxford university press

solvency rule and capital centralisation in a monetary union brancaccio and fontana 2013 have suggested that the central bank influences the solvency conditions of firms and households in the economic system this solvency rule is examined here within a stylised model of a monetary union characterised by different rates of accumulation and inflation across its two member countries the rule highlights the existence of a relationship between the interest rate set by the central monetary authority and the allocation of ownership of existing physical capital among the member countries of the monetary union i e the rates of capital centralisation the paper also shows the nexus between solvency and government debt sustainability and examines the implications of deflationary or currency devaluation policies for the solvency conditions

including sustainability criteria into inventory models research on sustainability performance has considerably enriched operations management literature in recent years however work with quantitative models is still scarce this paper contributes by revisiting classical inventory methods taking sustainability concerns into account we believe that reducing all aspects of sustainable development to a single objective is not desirable we thus reformulate the classical economic order quantity model as a multiobjective problem we refer to this model as the sustainable order quantity model then a multi echelon extension of the sustainable order quantity model is studied for both models the set of efficient solutions pareto optimal solutions is analytically characterized these results are used to provide some insights about the effectiveness of different regulatory policies to control carbon emissions we also use an interactive procedure that allows the decision maker to quickly identify the best option among these solutions the proposed interactive procedure is a new combination of multi criteria decision analysis techniques

the incidence of taxes a dynamic macroeconomic analysis abstract this paper analyzes the incidence of various tax changes using the intertemporal optimizing framework developed by brock and turnovsky the model contains a reasonably complete specification of the corporate sector in which firms have the choice of financial structure it also allows for a range of government financial policies although only one is considered in detail both the short run and the long run effects of changes in the personal income capital gains and corporate profit tax rates are analyzed it is shown that the effects of tax changes a vary between the short and long run b the effects of tax changes depend critically upon the financial structure adopted by forms and c may also depend upon government financial policy

the taylor principle and monetary policy approaching a zero bound on nominal rates quantile regression results for the united states and japan this paper offers a new approach that estimates the response of interest rates to inflation and the output gap at various points quantiles on the conditional distribution of interest rates this offers an improvement on empirical estimates conducted only at the mean and also allows us to test the propositions that policy shows greater aggression to inflation in the reaction function in terms of a greater response coefficient as interest rates reach low levels and increasing aggression as the lower bound is approached we find support for the taylor principle a more aggressive response to inflation than under a taylor rule but no detectable evidence of increasing aggression as the zero lower bound is approached in the us and japan

tobin s q and financial policy abstract recent research in macroeconomics has emphasized the importance of linking the financial and real sectors and working with optimizing models tobin s q model of investment would appear to provide a framework satisfying these two criteria in contrast to the original presentation of the q model the formal development has not recognized that the firm actively participates in a number of financial markets in this broader context q may be an uninformative and possibly misleading signal for investment expenditures we then endeavor to turn this negative theoretical result to positive advantage in resolving a number of empirical problems with q models

anticipated tax reforms and temporary tax cuts a general equilibrium analysis macroeconomic studies of tax policy in dynamic general equilibrium usually assume that reforms hit the economy unexpectedly and last forever here we explore how previous results change when we allow policy changes to be pre announced and of finite duration and when these facts are anticipated by households and firms quantitatively we demonstrate a headstart advantage from pre announcement that is never caught up by a surprising reform the welfare gain stemming from a 5 year announcement phase of a corporate tax cut for example is estimated to be around 10 percent of the total gain from the reform we show that impulse responses of important variables like firm value dividends and investment differ qualitatively depending on whether the reform comes expected or not we are also able to demonstrate a genuine welfare gain from temporary tax cuts impulse responses generated by our numerical method can be retraced by phase diagram analysis which facilitates explanation and interpretation of the produced results

tobin s q investment and the endogenous adjustment of financial structure abstract should q theory be modified to take account of financial structure this paper analyzes a general equilibrium q model where financial structure affects firm value agency costs and taxes combine to yield an interior solution for the endogenous debt equity ratio although q is still a sufficient statistic for investment the endogenous adjustment of financial structure alters the relation between the interest rate and investment in this model an increase in the corporate tax rate could either raise or lower the steady state capital stock furthermore both q and investment could jump in opposite directions to that of their steady state values

output the stock market and interest rates this paper develops a simple model of the determination of output the stock market and the term structure of interest rates the model is an extension of the is lm model and borrows from it the assumption that output is determined by aggregate demand and that the price level can only adjust over time to its equilibrium value however whereas the is lm emphasizes the interaction between the interest rate and output this model emphasizes the interaction between asset values and output asset values rather than the interest rate are the main determinants of aggregate demand and output current and anticipated output and income are in turn the main determinants of asset values it is this interaction that the model intends to capture its goal is to characterize the joint response of asset values and output to changes in the environment such as changes or announcement of changes in monetary and fiscal policy as the above brief description makes clear anticipations are central to the story the assumption made in this paper will be one of rational expectations the paper is organized as follows section i describes the model and sections ii iv characterize the behavior of the economy under the extreme but convenient assumption that prices are fixed forever sections v and vi extend the analysis to the case where prices adjust over time to their equilibrium value

decision support systems for semi structured buying decisions abstract using recent research on evolutionary systems design and on the process of learning preferences in multicriteria decision making a decision support system dss is proposed for semi structured buying decisions the general decision process model involves four phases and feedbacks among them 1 1 selecting criteria and an admissible set of alternatives products 2 2 searching for consistency between the decision maker s wholistic preference and an analytical model of it 3 3 assesing a compromise preference model 4 4 evaluating the alternative products using the compromise preference model an illustrative example purchasing a car is presented we conclude with some brief remarks on implementation of the dss on microcomputers and extension to the case of several decision makers

capital tax reform corporate finance and economic growth and welfare abstract recent empirical studies have revealed a strong impact of tax changes on corporate finance yet models of economic growth usually neglect financial structure of the representative firm in order to investigate whether the consideration of firm finance modifies the estimated outcome of capital tax reforms a corporate sector is introduced in three popular models of economic growth the paper explores analytically the impact of taxation on structures of finance and production and gives a quantitative reassessment of growth and welfare effects of tax reforms in the u s economy a general result is that standard models of exogenous and endogenous growth overestimate the growth effect and underestimate the welfare gain from tax reform

the liquidity of money in his general theory keynes implicitly defines liquidity as stability of value with respect to changes in the state of long term expectation this contrasts with the usual conception of liquidity as convertibility and with leading post keynesian interpretations the proposed definition explains why keynes places so much emphasis on liquidity while assuming perfect markets for capital goods and writes of the liquidity of land it also sheds new light on the distinction keynes makes between the liquidity of money and the liquidity of organised investment markets

the q theory of investment with many capital goods the q theory of investment which relates investment to the ratio of market to replacement value of capital has attracted considerable attention in a recent series of papers for instance a q variable has been used as an independent variable in empirical investment equations estimated by george von furstenberg 1977 von furstenberg et al 1980 burton malkiel et al 1979 and others these papers however leave somewhat unclear the theoretical rationale for using q as an investment determinant this has motivated work by hiroshi yoshikawa 1980 lawrence summers 1981 michael salinger and summers 1981 and fumio hayashi 1982 who show that under certain conditions the rate of investment of a sharevalue maximizing firm is indeed a function of q this is an important result because it shows that investment equations with q an independent variable are not ad hoc constructions rather they are grounded in a theory of the firm with an appealing behavioral hypothesis viz value maximization an important assumption underlying this research is that capital can be treated as a homogeneous good of course this is an extremely common assumption in the analysis of investment and is not particularly more bothersome in the q theory context than elsewhere nonetheless there are certain situations where it may be desirable or even essential to be able to study investment disaggregated by type of capital good thus the purpose of this paper is to examine whether and how the q theory can be extended to this more general case 1 intuitively one would expect some difficulty with the q theory in the many capitalgood context as already noted by james tobin and william brainard 1977 p 243 and by salinger and summers p 12 one way to see why is to recall the tobin brainard distinction between marginal and average q as hayashi writes

comparative evaluation of post keynesian interest rate rules income distribution and firms debts for macroeconomic performance this article investigates the macroeconomic effects of firms debts and income distribution on economic growth and inflation under three different post keynesian interest rate rules the kansas city rule the smithin rule and the pasinetti rule by setting up a dynamic post keynesian model after reviewing debates on the post keynesian interest rate policies this article evaluates the relative merits of the three rules in their relationship with economic growth regimes and inflation dynamics accordingly this article explicitly shows that i a policy rule works effectively under some economic growth and inflation patterns but not necessarily under other patterns ii a policy rule contributing to high economic growth may not always be compatible with stabilisation of economic growth and iii the macroeconomic effects of debt and income distribution on economic growth and inflation are closely related to the choice of interest rate rule

bitcoin and the legitimacy crisis of money the virtual currency and payment project bitcoin intends to challenge the current monetary and payment system that finds itself in a legitimacy crisis in the aftermath of the financial market turmoil of 2008 in examining the governance of the bitcoin system i try to assess its potential to create input and output legitimacy as a payment system and as a monetary system in comparison with current practice

taxation corporate financial policy and the cost of capital the cost of capital plays an important role in the allocation of resources among competing uses in a decentralized market system the purpose of this paper is to organize and present what is known and what is hypothesized about the effects of taxation on the incentive to invest via the cost of capital taking full account of important issues that arise independently from the question of taxation included in the analysis is a discussion of empirical findings about the interaction of inflation and taxation in influencing the incentive to invest and a treatment of taxation and uncertainty this abstract was borrowed from another version of this item

optimal monetary policy when interest rates are bounded at zero abstract this paper characterizes the optimal monetary policy reaction function in the presence of a zero lower bound on the nominal interest rate we analytically prove and numerically show that the function is highly non linear more expansionary and more aggressive than the taylor rule we then test its empirical validity taking the case of japan in the 1990s qualitatively we find some evidence of non linear monetary policy quantitatively we find the actual monetary policy to be too contractionary during the first half of the decade while the low interest policy during the latter half turns out to be fairly consistent with the simulated path

monetary policy and the zero bound to interest rates a review1 this paper reviews the literature on what the zero bound to nominal interest rates implies for the conduct of monetary policy the aim is to evaluate the risks of hitting the zero bound and to evaluate policies that are said to be able to reduce that risk or policies that are proposed as means of helping the economy escape if it is in a zero bound trap i conclude that policies aimed at cure are arguably more uncertain tools than those aimed at prevention so prevention is a less risky strategy for policymakers but since the risks of hitting the zero bound seem quite small anyway and the risks of encountering a deflationary spiral smaller still it is conceivable that inflation objectives that typify modern monetary regimes already have more than enough insurance built into them to deal with the zero bound problem

making sense of a crank case monetary diversity in argentina 1999 2003 based on empirical data this study discusses the introduction acceptance and circulation of two complementary currencies in argentina that do not fit well in the main approaches to the nature of money these two monetary circuits provincial and community currencies were introduced as units of account to denominate the value of debt and circulated as means of payment to overcome monetary stringency during the crisis of 1999 2003 after discussing several theories on the nature of money we reflect on the institutional significance of currency circuits as concurrent and rather stable pairs of trade and money we suggest that several theories of money need to be combined to account for the variety and heterogeneity of daily monetary practices in a broad spectrum of countries

an empirical structural model of aggregate demand abstract this paper estimates a structural model of aggregate demand it attempts to avoid two of the shortcomings of most existing macroeconometric models the structure of the model is specified so as to be approximately policy invariant to eliminate the pretesting from which most published estimated models suffer all regression run are reported as the model contains consumption investment and money demand functions close in specification to existing ones it should help the reader judge the reliability of existing estimated functions the estimated model shows a relatively small direct dependence of aggregate demand on the past a much larger dependence on the anticipated future

conflict of interest bond rating and the value maximization rule a number of authors have noted that when a firm issues risky debt in the absence of binding state contingent contracts the maximize present value rule becomes ambiguous this paper shows that incomplete asymmetric information can explain why the firm will make value maximizing decisions when there is a conflict of interest between shareholders and bondholders the reputation effect of d m kreps and r wilson 1982 and its implications for the pricing of securities is at the heart of this explanation copyright 1987 by the review of economic studies limited

a preference disaggregation decision support system for financial classification problems abstract classification is one of the most extensively studied problems in the fields of multivariate statistical analysis operations research and artificial intelligence decisions involving a classification of the alternative solutions are of major interest in finance since several financial decision problems are best studied by classifying a set of alternative solutions firms loan applications investment projects etc in predefined classes this paper proposes an alternative approach to the classical statistical methodologies that have been extensively used for the study of financial classification problems the proposed methodology combines the preference disaggregation approach a multicriteria decision aid method with decision support systems more specifically the financial classification finclas multicriteria decision support system is presented the system incorporates a plethora of financial modeling tools along with powerful preference disaggregation methods that lead to the development of additive utility models for the classification of the considered alternatives into predefined classes an application in credit granting is used to illustrate the capabilities of the system

how useful is the concept of the natural real rate of interest for monetary policy the natural rate of interest plays a key role in wicksell s cumulative process as well as in modern monetary equilibrium models of the business cycle it constitutes a useful concept for the theoretical analysis of the interdependence of monetary policy and economic fluctuations however the usefulness of this concept for the practice of monetary policy is limited especially owing to the fact that the natural real rate of interest and its law of motion cannot be measured with satisfying precision

what is wrong with taylor rules using judgment in monetary policy through targeting rules it is argued that inflation targeting is best understood as a commitment to a targeting rule rather than an instrument rule e ither ageneral targeting rule explicit objectives for monetary policy or a specific targeting rule a criterion for the forecasts of the target variables to be fulfilled essentially the equality of the marginal rates of transformation and substitution between the target variables targeting rules allow the use of judgment and extramodel information are more robust and easier to verify than optimal instrument rules and they can nevertheless bring the economy close to the socially optimal equilibrium

graph representation of balance sheets from exogenous to endogenous money a graph representation of the financial relations in a given monetary structure is proposed it is argued that the graph of debt liability relations is naturally organized and simplified into a tree structure around banks and a central bank indeed this optimal graph allows to perform payments very easily as it amounts to the suppression of loops introduced by pending payments using this language of graphs to analyze the monetary system we first examine the systems based on commodity money and show their incompatibility with credit after dealing with the role of the state via its ability to spend and raise taxes we discuss the chartalist systems based on pure fiat money which are the current systems we argue that in those cases the treasury and the central bank can be meaningfully consolidated after describing the interactions of various autonomous currencies we argue that fixed exchanged rates can never be maintained and we discuss the controversial role of the imf in international financial relations we finally use graph representations to give our interpretation on open problems such as the monetary aggregates the sectoral financial balances and the endogenous nature of money indeed once appropriately consolidated graphs of financial relations allow to formulate easily unambiguous statements about the monetary arrangements

the stories we tell a reconsideration of as ad analysis this paper explains that the as ad model as currently presented in the tests is seriously flawed it does not fulfill the minimum requirement of a model logical consistency its component parts are derived from models that reflect different and inconsistent models of the economy moreover the appropriate disequilibrium adjustment story that appropriately accompanies it is inconsistent with observed reality in this alternative model keynesian adjustment occurs through shifting as ad curves along institutionally determined price level vectors rather than through movements along the as ad curves

an intertemporal model of saving and investment this paper characterizes a market economy with infinitely long lived consumers and value maximizing firms which face costs of adjustment for capital the temporary equilibrium of this economy is similar to the short run equilibrium of standard macroeconomic models consumption is a function of wealth investment is related to the value of firms equilibrium between aggregate demand and aggregate supply is achieved by the endogenous adjustment of the sequence of current and future interest rates the dynamic behavior of output consumption and investment in this economy is the same as in an optimal growth model with adjustment costs the paper shows this equivalence and then uses it together with the equivalence of taxes to technological shocks to study the dynamic effects of fiscal policy

a multi criteria evaluation framework for tradable white certificate schemes recent years have witnessed regained political momentum on energy efficiency and interest in establishing markets is growing as a result tradable white certificate twc schemes of differing design have been implemented in great britain italy and france much attention is being paid to justifying and evaluating such schemes in this paper we develop and apply a multi criteria framework for evaluating twc schemes an approach that attempts to cover their individual design features a broad evaluation is conducted regarding energy saving and environmental effectiveness economic efficiency cost effectiveness transaction costs political feasibility administrative burden and technical change the results show the design and performance of twc schemes to be case and context specific and generalisations are thus inappropriate this evaluation supports the cost effectiveness modelled for the british scheme and the assumption that a twc scheme is an economically efficient policy instrument for the other more complex twc schemes more data and experience are needed to judge their ex post merit on the whole the proposed multi criteria evaluation requires considerable data and complementary methods however the framework improves the understanding of the broad effects and attributes of twc schemes it deals with various empirical and normative aspects that can be applied in their evaluation

the evaluation criteria of the venture capital investment activity an interactive assessment abstract in this paper the modelling of venture capital decision making is being attempted using a multicriteria decision support system the minora system based on the interactive use of the uta ordinal regression model first a review of the literature on the evaluation criteria for venture capital investment is outlined and the general methodology of financing firms is presented then a real world application of the minora system is developed this has been done in a french venture capital firm and concerned the assessment of an analytical evaluation model of firms
