the new pattern of regional unemployment causes and policy significance in common with most oecd countries unemployment in britain has differed significantly between regions but the persistence of relative regional unemployment rates in britain has been until recently particularly striking however during the i990 93 recession the relative regional unemployment pattern changed significantly for the first time in seventy years our primary purpose here is to understand these recent changes and to examine what might be learned about the contribution of economic policies to the amelioration of both regional unemployment rate differentials and the amplitude of regional unemployment cycles finally we ask whether there are any policy lessons to be drawn from the recent cycles in regional unemployment patterns which might provide insight into the amplitude of macro economic cycles

an investigation of the gains from commitment in monetary policy this paper proposes a simple framework for analyzing a continuum of monetary policy rules characterized by differing degrees of credibility in which commitment and discretion become special cases of what we call quasi commitment the monetary policy authority is assumed to formulate optimal commitment plans to be tempted to renege on them and to succumb to this temptation with a constant exogenous probability known to the private sector by interpreting this probability as a continuous measure of the lack of credibility of the monetary policy authority we investigate the welfare effect of a marginal increase in credibility our main finding is that in a simple model of the monetary transmission mechanism most of the gains from commitment accrue at relatively low levels of credibility in our benchmark calibration a commitment expected to last for only 6 quarters is enough to bridge 75 of the welfare gap between discretion and commitment this seems to justify the well known concern of monetary policy makers about their credibility even in a world with limited access to commitment technologies

nominal price rigidity money supply endogeneity and business cycles abstract this paper investigates the ability of nominal price rigidity to explain the co movement of inflation with the cyclical component of output observed in the post war u s data a dynamic general equilibrium model is constructed with the introduction of monopolistic competition and nominal price rigidity in a standard real business cycle model allowing for an endogenous money supply rule it is then demonstrated that sticky price models can explain the observed associations between movements in inflation and output much better than flexible price models this result depends little on whether money supply is assumed to be endogenous or not

discretionary monetary policy and the zero lower bound on nominal interest rates abstract ignoring the existence of the zero lower bound on nominal interest rates one considerably understates the value of monetary commitment in new keynesian models a stochastic forward looking model with an occasionally binding lower bound calibrated to the u s economy suggests that low values for the natural rate of interest lead to sizeable output losses and deflation under discretionary monetary policy the fall in output and deflation are much larger than in the case with policy commitment and do not show up at all if the model abstracts from the existence of the lower bound the welfare losses of discretionary policy increase even further when inflation is partly determined by lagged inflation in the phillips curve these results emerge because private sector expectations and the discretionary policy response to these expectations reinforce each other and cause the lower bound to be reached much earlier than under commitment

the regional transmission of uk monetary policy dow s c and montagnoli a 2007 the regional transmission of uk monetary policy regional studies 41 797 808 concerns have been raised in the media about a one size fits all monetary policy for the uk if there are diverse economic conditions in different regions then a unitary monetary policy cannot suit all the purpose of this paper is to explore this issue further by breaking it down into two separate issues first there is the more conventional way of considering the question in terms of the effect of a particular interest rate change on regions experiencing different economic conditions this requires a consideration of the nature and causes of regional economic disparities in the uk and how these might be affected by particular interest rate changes but there is further the question of how monetary policy is transmitted to the different regions the possibility is considered that there may be regional differences in how a particular monetary policy is translated into different financial

generation capacity adequacy in interdependent electricity markets this paper deals with the practical problems related to long term security of supply in regional electricity markets with transmission constraints differences between regulatory policies and market designs in terms of generation adequacy policies may distort the normal functioning of the neighboring markets as well as the reliability of supply we test the effect of heterogeneous regulatory design between two interdependent markets energy only market price capped market without capacity mechanisms and price capped markets with forward capacity contracts obligation we rely on a long term market simulation model in system dynamics that characterizes expansion decision in a competitive regime the results show that differences in market designs affect both price and reliability of supply in the two markets we examine both the short and long terms effect and how free riding may occur where capacity adequacy policies are adopted in one market but not the other the main finding is that the lack of harmonization between local markets in policies to ensure capacity adequacy may lead to undesirable side effects

how important is precommitment for monetary policy we quantify the welfare differential between precommitment and discretionary monetary policy in three estimated models of the u s economy by calculating the permanent deviation of inflation from target that in welfare terms is equivalent to moving from discretion to precommitment using a range of reasonable central bank preference parameters this inflation equivalent ranges from 0 05 to 3 6 percentage points with a mid point of either 0 15 or 1 1 5 percentage points depending on the model in addition to the degree of forward looking behavior we show that the existence of transmission lags and or information lags is crucial for determining the welfare gain from precommitment

enhanced operational reserve as a tool for development of optimal energy mix abstract the aim of this article is to present a novel capacity remuneration mechanism concept that differentiates the level of financial support according to the technology and parameters of the new power plants new power plants that are to be constructed should guarantee the highest level of security of electricity supply and be consistent with actual energy policy carried out by a country thus the proposed remuneration system is based on an operational reserve system which is currently implemented in poland the proposed system distinguishes new power generating assets according to a total assessment based on three factors type of technology including emission benchmark flexibility and location addressing issue of brown or green field investment and conditions of power system operation existing power plants are also subsidized by the proposed mechanism however their remuneration is not based on their characteristics the details of the proposed mechanism a cost analysis and a standardized evaluation procedure are described in the paper the concept itself is universal and can be intruded in every power system that must overcome capacity problem

optimal simple and implementable monetary and fiscal rules welfare maximizing monetary and fiscal policy rules are studied in a model with sticky prices money and distortionary taxation the ramsey optimal policy is used as a point of comparison the main findings are the size of the inflation coefficient in the interest rate rule plays a minor role for welfare it matters only insofar as it affects the determinacy of equilibrium optimal monetary policy features a muted response to output interest rate rules that feature a positive response to output can lead to significant welfare losses the welfare gains from interest rate smoothing are negligible optimal fiscal policy is passive the optimal monetary and fiscal rule combination attains virtually the same level of welfare as the ramsey optimal policy

interactions of commitment and discretion in monetary and fiscal policies we consider monetary scal interactions when the monetary authority is more conservative than the scal with both policies discretionary 1 nash equilibrium yields lower output and higher price than the ideal points of both authorities 2 of the two leadership possibilities scal leadership is generally better with scal discretion monetary commitment yields the same outcome as discretionary monetary leadership for all realizations of shocks but scal commitment is not similarly negated by monetary discretion second best outcomes require either joint commitment or identical targets for both authorities output socially optimal and price level appropriately conservative or complete separation of tasks jel e61 e63

strategic monetary and fiscal policy interactions an empirical investigation this paper identifies leadership regimes in monetary fiscal policy interactions in three countries the uk the us and sweden we specify a small scale structural general equilibrium model of an open economy and estimate it using bayesian methods we assume that the authorities can act strategically in a non cooperative policy game and compare different leadership regimes we find that the model of fiscal leadership gives the best fit for the uk and sweden while in the us the nash or non strategic regime dominates we assess the extent to which policy maker preferences reflect microfounded social preferences

sensitivity of reserve margin to factors influencing investment behaviour in the electricity market of england and wales abstract the electricity generation and distribution industries of england and wales have recently undergone major re structuring as part of the privatization process of taking them out of the public sector on the generation side three major companies have been created which compete both with each other and with the new independent companies who are expected to enter the market trading between generators and distributors is controlled centrally by a pool system which attempts to ensure the optimal operation of the system in the short term and gives a pricing signal for longer term investment this pricing signal depends upon an a priori loss of load probability this paper is intended to provide insights into how the investment in capacity for generation could evolve according to various regulatory conditions economic assumptions degrees of competition and the strategic behaviour of the separate companies using a system dynamics approach a simulation model of investment is developed to generate insights into the volatility of the reserve margin variations in the loss of load probability and the various market share scenarios the degree of uncertainty in the demand the amount of information exchange between competitors and the degree of foresight in planning are considered as well as different financial or market share objectives for companies

capital structure decisions during a firm s life cycle the study reported here examines the financing choices of small and medium sized firms i e those most vulnerable to information and incentive problems through the lens of the business life cycle we argue that the controversy in the empirical literature regarding the determinants of capital structure decisions is based on a failure to take into account the different degrees of information opacity and consequently firms characteristics and needs at specific stages of their life cycles the results show that in a bank oriented country firms tend to adopt specific financing strategies and a different hierarchy of financial decision making as they progress through the phases of their business life cycle contrary to conventional wisdom debt is shown to be fundamental to business activities in the early stages representing the first choice by contrast in the maturity stage firms re balance their capital structure gradually substituting debt for internal capital and for firms that have consolidated their business the pecking order theory shows a high degree of application this financial life cycle pattern seems to be homogeneous for different industries and consistent over time

regional interest rate pass through in italy this paper estimates the pass through and speed of adjustment of italian regional interest rates to changes in the money market rate for the period 1998q1 2009q4 our main findings suggest that the markup for the lending rates that banks charge are generally higher in the south than in the north moreover our results indicate that the pass through tends to be longer in southern regions we find little evidence supporting the hypothesis of asymmetric adjustment in the lending rates but detect some evidence supporting upward rigidity in the regional deposit rates

green energy market development in germany effective public policy and emerging customer demand this paper reviews the development of renewable energy in germany from 1973 to 2003 it investigates the relative importance of energy policy and green power marketing in shaping the renewable energy market more than a decade of consistent policy support for renewables under the feed in law streg and its successor eeg has been an important driver for increasing renewable electricity generation to date putting the country in a better position than most of its peers when it comes to achieving european union targets for renewable energy green power marketing driven by customer demand on the other hand is growing but has had limited measurable impact so far we discuss potential intangible benefits of green power marketing and scenarios for future market development the paper concludes with lessons that can be learned from the german case for policy design and market development in other countries

the merit order effect a detailed analysis of the price effect of renewable electricity generation on spot market prices in germany the german feed in support of electricity generation from renewable energy sources has led to high growth rates of the supported technologies critics state that the costs for consumers are too high an important aspect to be considered in the discussion is the price effect created by renewable electricity generation this paper seeks to analyse the impact of privileged renewable electricity generation on the electricity market in germany the central aspect to be analysed is the impact of renewable electricity generation on spot market prices the results generated by an agent based simulation platform indicate that the financial volume of the price reduction is considerable in the short run this gives rise to a distributional effect which creates savings for the demand side by reducing generator profits in the case of the year 2006 the volume of the merit order effect exceeds the volume of the net support payments for renewable electricity generation which have to be paid by consumers

the regional implications of macroeconomic policy this article examines the relative impact of changes in uk fiscal and monetary policy on the economies of the uk regions this is done by first considering the relative importance of fiscal flows and balances to the uk regions and then assessing their sensitivity to fiscal policy changes second the impact of monetary policy on the regions is considered in four cases these are direct effects on spending exchange rate effects income effects and asset price effects the conclusions are that different policy levers have markedly different regional implications with southern regions being more sensitive to changes in income taxes and government consumption and investment while northern regions are more sensitive to changes in national insurance and transfer payments all regions have become more sensitive to interest rate changes over the past decade but regions in the south are considerably more vulnerable particularly to any knock on effect on house prices copyright 1995 by oxford university press

the role of regulatory learning in energy transition the case of solar pv in brazil abstract an important problem that has attracted significant amount of attention within the context of energy transitions is the carbon lock in a situation in which energy systems are locked in to high carbon technologies through a path dependent process several measures to avoid the carbon lock in involve technology specific measures which in turn implies that those measures may result in an energy system locked in to certain low carbon technologies we consider that the brazilian system needs policies to escape the carbon lock in which are based on providing incentives to low carbon technologies we develop an analytical framework to analyze the role of regulatory institutions in the possible lock in to utility scale photovoltaic in the sense that they create barriers to the adoption of distributed generation photovoltaic we show that the definition of a process to adapt the institutional framework in a context of stress in the innovation system is crucial for the adoption of new technologies applying our framework to the brazilian power sector we observe that only when regulators consider the possibility that the system is locked in to centralized production technologies and not when they just consider the carbon lock in they manage to eliminate barriers to distributed generation based on solar pv

capacity adequacy in power markets facing energy transition a comparison of scarcity pricing and capacity mechanism this article analyses how a capacity mechanism can address security of supply objectives in a power market undergoing an energy transition that combines energy efficiency efforts to stabilise demand and a rapid increase in the proportion of renewables to analyse this situation power markets are simulated over the long term with a system dynamics model integrating new investment and closure decisions this last trait is relevant to studying investment in power generation in mature markets undergoing policy shocks the energy only market design with a price cap with and without a capacity mechanism is compared to scarcity pricing in two investment behaviour scenarios with and without risk aversion the results show that the three market designs lead to different levels of risk for peaking unit investment and results thus differ according to which risk aversion hypothesis is adopted assuming a risk neutral investor the results indicate that compared to an energy only market with a price cap at 3 000 mwh an energy only market with scarcity pricing and the market design with a capacity mechanism are two efficient options to reach similar levels of load loss but under the hypothesis of risk aversion the results highlight the advantage of the capacity mechanism over scarcity pricing

cost effectiveness of renewable electricity policies we analyze policies to promote renewable sources of electricity a portfolio standard rps raises electricity prices and primarily reduces gas fired generation a knee of the cost curve exists between 15 and 20 goals for 2020 in our central case and higher natural gas prices lower the cost of greater reliance on renewables a renewable energy production tax credit lowers electricity price at the expense of taxpayers which limits its effectiveness in reducing carbon emissions and it is less cost effective at increasing renewables than a portfolio standard neither policy is as cost effective as a cap and trade policy for achieving carbon emission reductions

counting on the neighbours challenges and practical approaches for cross border participation in capacity mechanisms capacity mechanisms have been implemented in an uncoordinated way by many countries in europe in recent years to ensure security of supply the european commission has defined via the state aid guidelines principles to minimize their impact on trade and competition in european electricity markets the paper identifies the different drivers of these national reforms maps the key issues associated with the coordination of capacity mechanisms across countries and explores alternative approaches to allow for explicit cross border participation in capacity mechanisms

do support systems for res e reduce eu ets driven electricity prices abstract support systems for electricity from renewable energy sources res e can reduce electricity prices which have also been influenced by a co2 emission trading scheme ets additional res e substitutes electricity from fossil fuels and thus co2 emissions are reduced the demand for emission reductions is lowered as a result the co2 price is also reduced consequently the wholesale price for electricity decreases however most res e support systems are financed via the electricity market which increases the retail electricity price an assessment for germany shows that retail electricity prices in the first trading period of the eu ets 2005 2007 are lowered by 2 6 euro mwh due to additional res e considering the complete eu the effect is substantially higher this paper describes the effect and the influence of different policy designs it develops an approach for assessing the effect and applies it for the case of germany and roughly estimates the effect for the eu

emu and the regional impact of monetary policy rodriguez fuentes c j and dow s c 2003 emu and the regional impact of monetary policy reg studies 37 969 980 in this paper we focus on a topic which has been attracting renewed interest because of monetary unification in europe the regional dimension of national monetary policies most of the debate over the regional implications of the euro has been developed within the optimum currency area framework according to this theory european monetary policy would have regional effects when the countries of the euro zone had such structural differences as to produce asymmetric shocks these asymmetrical effects could only be offset by labour mobility and wage price flexibility however we argue here that in addition european monetary policy may have more general regional effects including in particular by producing a higher instability in the pattern of credit availability for some peripheral regions this latter possibility and the forces underlying it are explored here both at the theoreti

fiscal policy under loose commitment due to time inconsistency or political turnover policymakers promises are not always fulfilled we analyze an optimal fiscal policy problem where the plans made by the benevolent government are periodically revised in this loose commitment setting the properties of labor and capital income taxes are significantly different than under the full commitment and no commitment assumptions because of the occasional reoptimizations the average capital income tax is positive even in the long run also the autocorrelation of taxes is lower their volatility with respect to output increases and the correlation between capital income taxes and output changes sign our method can be used to analyze the plausibility and the importance of commitment in a wide class of dynamic problems

evaluating the effect of technology transformation on the electricity utility industry abstract the technology shift from fossil fuelled systems to renewable energies has been promoted by governments with the purpose of decarbonising the power industry however rapid technology progress has prompted disruptive changes that transformed market structures incumbent electricity utilities particularly those based on fossil fuel plant are shifting from their stable and predictable situation to confront challenges from those that offer alternative energy services in this new environment the industry will benefit from mid to long term sector foresight the paper studies the potential impact of renewable energy sources res on electricity systems specifically on the generation and distribution businesses for this purpose a fairly detailed and integrated supply and demand based system dynamics model has been built to quantify the extent of their potential impact the model disaggregates the household sector which may generate a significant part of its electricity using rooftop solar energy this is illustrated by examining a utility engaged in the generation and distribution businesses in the colombian electricity market through simulation runs this paper concludes that subject to policy and all other things remaining equal solar rooftop generation is a major threat for utilities while the generation business is most affected in the short term the distribution business is the one most impacted in the long term and jointly they may induce the utility death spiral

an analysis of a forward capacity market with long term contracts we analyze the effectiveness of a forward capacity market fcm with long term contracts in an electricity market in the presence of a growing share of renewable energy an agent based model is used for this analysis capacity markets can compensate for the deteriorating incentive to invest in controllable power plants when the share of variable renewable energy sources grows but may create volatile prices themselves capacity markets with long term contracts have been developed e g in the uk to stabilize capacity prices in our analysis a fcm is effective in providing the required adequacy level and leads to lower cost to consumers and more stable capacity prices as compared to a yearly capacity market in case of a demand shock a fcm may develop an investment cycle but it still maintains security of supply its main effect on the power plant portfolio is more investment in peak plant

an improved mechanism for capacity payment based on system dynamics modeling for investment planning in competitive electricity environment many countries have experienced restructuring in their electric utilities this restructuring has presented the power industries with new challenges the most important of which is long term investment planning under uncertain conditions this paper presents an improved mechanism for capacity payment the mechanism has been investigated based on system dynamic modeling in our proposed mechanism generators will recover a part of their investment through capacity payment while the payment for any plant remains constant during the operation period it depends on the investment needed to build it the main factors affecting long term planning have been considered in our model the approach can be used to investigate the effects of fixed as well as variable capacity payment in market investment we used the probability density function of load as a new concept to calculate average market price delays in unit constructions estimation of demand and market capacity growth during construction periods have been included in the proposed algorithm as parameters which affect the regulator s decision for changing capacity payment the model can be used by regulators to investigate strategies that may affect the fluctuations in the market

how to correct for long term externalities of large scale wind power development by a capacity mechanism this paper deals with the practical problems related to long term security of supply in electricity markets in the presence of large scale wind power development the success of recent renewable promotion schemes adds a new dimension to ensuring long term security of supply it necessitates designing second best policies to prevent large scale wind power development from distorting long run equilibrium prices and investments in conventional generation and in particular in peaking units we rely upon a long term simulation model which simulates electricity market players investment decisions in a market regime and incorporates large scale wind power development in the presence of either subsidized or market driven development scenarios we test the use of capacity mechanisms to compensate for long term effects of large scale wind power development on prices and reliability of supply the first finding is that capacity mechanisms can help to reduce the social cost of large scale wind power development in terms of decrease of loss of load probability the second finding is that in a market based wind power deployment without subsidy wind generators are penalised for insufficient contribution to the long term system s reliability

monetary conservatism and fiscal policy abstract does an inflation conservative central bank a la rogoff 1985 remain desirable in a setting with endogenous fiscal policy to provide an answer we study monetary and fiscal policy games without commitment in a dynamic stochastic sticky price economy with monopolistic distortions monetary policy determines nominal interest rates and fiscal policy provides public goods generating private utility we find that lack of fiscal commitment gives rise to excessive public spending the optimal inflation rate internalizing this distortion is positive but lack of monetary commitment generates too much inflation a conservative monetary authority thus remains desirable when fiscal policy is determined before monetary policy each period the monetary authority should focus exclusively on stabilizing inflation monetary conservatism then eliminates the steady state biases associated with lack of monetary and fiscal commitment and leads to stabilization policy that is close to optimal

the value of monetary policy commitment under imperfect fiscal credibility abstract a central finding of the previous monetary policy research is that commitment to a policy rule results in substantial welfare gains in this paper i reevaluate the value of monetary policy commitment in an environment where monetary and fiscal policies are conducted by separate branches of the government i find that welfare gains from monetary policy commitment can be small if the fiscal authority can exercise a certain degree of commitment on his own i also find that a moderate improvement in fiscal credibility can substantially reduce the welfare gains from full commitment in monetary policy under monetary leadership under fiscal leadership the degree of fiscal credibility does not affect the welfare gains from monetary commitment
