the new electricity market of singapore regulatory framework market power and competition abstract this study examines whether the new electricity market of singapore nems is functioning at a workable level of competition the generation market of the nems appears highly concentrated by a four firm concentration ratio or the herfindahl hirschman index however other measures of market power present that the nems is working at close to a competitive market first there seems to be a number of effective competitors in the market second supply margin assessment and residual supply index support that the market is competitive though there are some possibilities in which the largest generator or a few large generators jointly could still have market power third the lerner index of the nems shows that the generation market is fairly competitive and the lerner index adjusted with an industry level price elasticity of demand implies that there has not been much exercise of market power finally vesting contracts a contractual obligation of a specified quantity of electricity supply to the market have appeared to be a strong and effective tool to mitigate market power in the nems the vesting contracts are considered the force behind the lowering in the average uniform singapore electricity price and the lerner index in 2004

causality between public expenditure and national income this paper deploys the granger method to determine the directions and patterns of causality between national income and total as well as various components of public expenditure empirical results based on the data for india 1950 81 suggest that while at the disaggregate level the causal process is rather diverse it is essentially feed back type at the aggregate level it neither confirms the wagnerian income public expenditure nor the keynesian public expenditure national income view the paper recommends that two variables be treated as jointly dependent in both the public finance and macroeconometric studies

identifying the effects of a lender of last resort on financial markets lessons from the founding of the fed abstract we use the founding of the federal reserve to identify the effects of a lender of last resort we examine stock return and interest rate volatility during september and october when markets were vulnerable because of financial stringency from the harvest stock volatility fell by 40 and interest rate volatility by more than 70 following the monetary regime change the drop is insignificant if major panic years are omitted from the analysis however because business cycle downturns occurred in the same year as financial crises our results suggest that the existence of the federal reserve reduced liquidity risk

ecb repo rate setting during the financial crisis abstract i estimate a reaction function for the ecb using an ordered logit model for the period 1999 2009 allowing for a smooth transition from one set of parameters to another i detect a rapid change in the middle of 2008

the causal factors of government expenditure growth in greece 1950 80 the notion of causal relationships is the basis on which the empirical testing of theoretical propositions rests this paper considers the risks from the wrong identification of causal relationships and then by using the pierce haugh test attempts to establish the correct causal patterns between various groups of government expenditures within the context of the greek economy from 1950 to 1980 and other variables which have appeared in the literature of the determinants of government expenditure growth

shifts in us federal reserve goals and tactics for monetary policy a role for penitence during the fi rst period starting in the mid 1920s the federal reserve offi cial during the fi rst period starting in the mid 1920s the federal reserve offi cial policy was to support high quality bank lending but not speculative lending this policy was to support high quality bank lending but not speculative lending this goal was set aside once in 1927 in an episode that many observers then blamed for goal was set aside once in 1927 in an episode that many observers then blamed for the economic collapse that followed the fi nancial crash of 1929 the fed was then the economic collapse that followed the fi nancial crash of 1929 the fed was then reluctant to increase the funds available to banks through the early 1930s even as reluctant to increase the funds available to banks through the early 1930s even as the great depression ravaged the economy the fed s concern with the volume and the great depression ravaged the economy the fed s concern with the volume and quality of lending in the setting of monetary policy did eventually wither however quality of lending in the setting of monetary policy did eventually wither however this only seems to have happened after the publication of friedman and schwartz this only seems to have happened after the publication of friedman and schwartz 1963 a revisionist history of the great depression that blamed its depth on the 1963 a revisionist history of the great depression that blamed its depth on the fed s inappropriate focus on productive lending fed s inappropriate focus on productive lending in the second period after the experience of post world war ii infl ation the in the second period after the experience of post world war ii infl ation the federal reserve in the 1950s was highly concerned with infl ation and was willing to federal reserve in the 1950s was highly concerned with infl ation and was willing to raise interest rates and bring on recessions to nip even modest infl ation rates in the raise interest rates and bring on recessions to nip even modest infl ation rates in the bud this brought withering criticism for the federal reserve on the grounds that bud this brought withering criticism for the federal reserve on the grounds that the recessions of 1957 and 1960 had been unnecessary by the mid 1960s some fed the recessions of 1957 and 1960 had been unnecessary by the mid 1960s some fed offi cials seem to have developed an aversion to creating recessions as a method of offi cials seem to have developed an aversion to creating recessions as a method of

credibility of a new monetary regime the currency board in bulgaria abstract low credibility reflected in persistent expectations of high inflation is the usual suspect in costly disinflation efforts a currency board is a monetary regime that attempts to establish credibility by reducing uncertainty regarding the inflation preferences of the policymaker and the environment in which the policymaker operates this paper uses unique survey data from bulgaria and finds that expected inflation is indeed lowered by the prospect of a currency board but to a different degree for different agents priors of the type of the policymaker and familiarity with the operation of the currency board contribute to explaining the differences

the adjustment of expectations to a change in regime a study of the founding of the federal reserve the founding of the federal reserve system in 1914 led to a substantial change in the behavior of nominal interest rates the authors examine the timing of this change and the speed with which it was effected they then use data on the term structure of interest rates to determine how expectations responded their results indicate that the change in policy regime was rapid and that individuals quickly understood the new environment they were facing copyright 1987 by american economic association

interest rate seasonals and the federal reserve it is widely believed that one of the federal reserve s first important monetary policy achievements was the deseasonalization of interest rates the federal reserve supposedly accomplished this by introducing appropriate seasonal movements into the supplies of currency and high powered money this view implicitly assumes that there was no interaction between american and foreign financial markets two findings are reported that challenge this conventional view first interest rate seasonals disappeared in the united states and other countries at approximately the same time second interest rate seasonal ended approximately 3 years before the seasonal movements of currency and high powered money changed

the bond price support program as a change in policy regimes evidence from the term structure of interest rates recently mankiw miron and weil 1987 argued that a change in policy regimes generally affects the public s expectations of future interest rates to illustrate this influence they compare the operation of the gold standard with the post gold standard regime in the united states they find that nominal short term interest rates were mean reverting before 1914 but became nonstationary after the creation of the federal reserve system we extend mankiw miron and weil s analysis by noting that the period from 1914 to the present cannot be characterized as one uninterrupted episode of policy discretion the united states temporarily abandoned discretion for a rule in the 1940s the fed and treasury agreed in april 1942 that the fed would adjust federal reserve credit in a manner that would produce relatively low market rates on longterm securities in particular the fed committed itself to support twenty year government bond prices at a level consistent with a 2 5 percent interest rate ceiling we investigate the possibility that the bond price support program of the 1940s conditioned the behavior of short term interest rates in a predictable way according to the expectation theory of the term structure a binding long term interest rate ceiling implies that an increase in the current short rate must cause the sum of the innovation and the change in future expected rates to be zero otherwise the long rate rises above the ceiling and the public perceives a violation of the bond rate commitment placing a binding ceiling on long term interest rates tends to make short term interest rates mean reverting

the federal reserve amendments of 1917 the beginning of a seasonal note issue policy the federal reserve adopted a policy of smoothing the seasonal behavior of interest rates after the amendments of 1917 these amendments reduced the collateral requirements for notes issued and thereby increased note issue capability notes in circulation more than doubled from june to december 1917 these amendments were passed to assist with war related financing as their timing coincided with the entry of the united states into world war i the smoothing of interest rates seasonals between 1914 and 1917 was not due to the founding of the federal reserve system but rather to trade related gold flows copyright 1991 by ohio state university press

restructuring and privatizing electricity industries in the commonwealth of independent states abstract this paper discusses the problems of restructuring electric power sectors in the countries of the commonwealth of independent states cis and examines in detail electric utility privatization in armenia privatization of electric power is expected to provide needed foreign investment increase efficiency and rationalize resource allocation progress in utility commercialization and industry and market restructuring in the cis is compared with that in central and eastern europe this paper presents the argument that throughout the cis little progress has been made because the investment needs of the electricity industry are not great compared with the strategic and political benefits that can be had by not privatizing and because the political and strategic dimensions of electrical power in the region create large risks for potential investors risk of investment is amplified by the large amount of spare generating capacity and continuing operation of significant government operated capacity armenia is found to provide a striking example of conditions and trends in the cis countries prospects for the future of restructuring are considered and specific measures that could be taken to improve those prospects are suggested

the central banking role of clearinghouse associations most of this clearinghouse currency was illegal but no one thought of prosecuting or interfering with its issuers as practically all of it bore the words payable only through the clearing house its holders could not demand payment for it in cash in plain language it was an inconvertible paper money issued without the sanction of law yet necessitated by conditions for which our banking laws did not provide when banks were being run upon and legal money had disappeared in hoards in default of any legal means of relief it worked effectively and doubtlessly prevented multitudes of bankruptcies which otherwise would have occurred andrew 1908b p 516

the pseudo liberalisation of russia s power sector the hidden rationality of transformation abstract this paper discusses the problems of adjustment of the russian power sector to the challenges for building up a new institutional structure according to political and market requirements and uncovers the reasons why the implementation of a pool regulation model initiated in 1992 was not successful it identifies the purely formal nature of implementation of the model as well as demonetarisation and the non payment problem as the special conditions in russia which were important for shaping the regulation model which evolved in recent years instead in two phases of the power sector s institutional development different incentives led to the emergence of a dual economic regulation model in which elements of the soviet command and supply system co exist with elements of market and entrepreneurship prospects of further regulatory reform are expected to result not from political decisions as was characteristic for regulatory reform in other countries but from economic interest of the already established players in the power market

the worldwide change in the behavior of interest rates and prices in 1914 abstract this paper evaluates the role of the destruction of the gold standard and the founding of the federal reserve both of which occured in 1914 in contributing to observed changes in the behavior of interest rates and prices after 1914 the paper presents a model of policy coordination in which the introduction of the fed stabilizes interest rates even it the gold standard remains intact and it offers empirical evidence that the dismantling of the gold standard did not play a crucial role in precipitating the changes in interest rate behavior

the federal reserve and panic prevention the roles of financial regulation and lender of last resort this paper surveys the role of the federal reserve within the financial regulatory system with particular attention to the interaction of the fed s role as both a supervisor and a lender of last resort the institutional design of the federal reserve system was aimed at preventing banking panics primarily due to the permanent presence of the discount window this new system was successful at preventing a panic in the early 1920s after which the fed began to discourage the use of the discount window and intentionally create stigma for window borrowing policies that contributed to the panics of the great depression the legislation of the new deal era centralized fed power in the board of governors and over the next 75 years the fed expanded its role as a supervisor of the largest banks nevertheless prior to the recent crisis the fed had large gaps in its authority as a supervisor and as lender of last resort with the latter role weakened further by stigma the fed was unable to prevent the recent crisis during which its lender of last resort function expanded significantly as the fed begins its second century there are still great challenges to fulfilling its original intention of panic prevention

regime changes and interest rate risk this paper employs the bai and perron 1998 2003 structural break methodology to investigate important structural shifts in us interest rates using data from 1890 01 to 1933 12 i find evidence for two large structural shifts in my monthly sample the second shift is found to start in september 1917 this supports the view of several studies which argue that us entry into world war 1 and subsequent wartime policies rather than the founding of the federal reserve in 1914 caused a major change in the behavior of nominal interest rates

the founding of the fed and the behavior of interest rates what can be learned from small samples abstract we take issue with angelini s 1994 claim that the founding of the federal reserve was not responsible for a change in the stochastic process followed by short term interest rates we argue that angelini s failure to reject the null hypothesis of no regime change around the date of the founding of the fed is due to the low power of his test

the start of interest rate smoothing in the us is it a monetary or fiscal story this article revisits the key issue raised by researchers who have empirically investigated the behaviour of short term us interest rates during the period 1890 1933 the seminal article of mankiw miron and weil 1987 argues that changes in the behaviour of nominal interest rates is best explained as a monetary regime shift that occurred with the founding of the federal reserve in 1914 this explanation is rejected by newbold lehybourne sollis and wohar 2001 who show that fiscal and regulatory changes driven by the needs of world war1 financing best explain the changing behaviour of interest rates that they identify as beginning in mid 1917 we find using three different statistical procedures that a structural break in the second moment of interest rates occurred in early 1915 this supports the monetary regime shift argument of mmw by illustrating that the interest rate smoothing policies of the fed can be observed as a variance break in short term interest rates

more on the behavior of interest rates and the founding of the fed abstract the paper addresses the issue of the impact of the foundation of the federal reserve system in 1914 on the behavior of short term interest rates empirical evidence is presented showing that no change of regime can be detected in the process governing short term rates in the years straddling the foundation of the fed since the behavior of this process did change in the decade 1910 1920 the paper discusses some historical events and institutional changes in the new york money market that had an impact on the behavior of short term interest rates between 1908 and 1920

testing for structural breaks trade off between power and spurious effects abstract i argue that in order to test for the effect of the foundation of the federal reserve on the behavior of short term interest rates extending the sample size on either side of the interval 1908 1918 will generate spurious results mankiw miron and weil 1987 1994 do not address data problems pointed out by other authors nor do they take into account some historical events and institutional changes in the new york money market that had an impact on the behavior of short term interest rates given these reasons for restricting the sample size i argue that their monte carlo evidence is largely irrelevant to the issue and that lack of power confirms my claim that no regime change can be detected astride the foundation of the fed

pareto optimal electricity tariff rates in the republic of armenia abstract the economic impact of electricity tariff rates on the residential sector of yerevan armenia is examined the effect of tariff design on revenue generation and equity measures is considered and the combination of energy pricing and compensatory social policies which provides the best mix of efficiency and protection for poor households is examined an equity measure is defined in terms of a cumulative distribution function which describes the percent of the population that spends x or less of their income on electricity consumption an optimal pareto efficient tariff is designed based on the analysis of survey data and an econometric model and the armenian tariff rate effective 1 january 1997 to 15 september 1997 is shown to be non optimal relative to this rate

a note on the expectations hypothesis at the founding of the fed abstract one of the most influential tests of the expectations hypothesis is mankiw and miron q j econ 101 1986 211 who found that the spread between the long term and short term rates provided predictive power for the short term rate before the fed s founding but not after they suggested that the failure of the expectations hypothesis after the fed s founding was due to the fed s practice of smoothing short term interest rates we show that their finding that the expectations hypothesis fares better prior to the fed s founding is due to the fact that the test they employ tends to generate results that are more favorable to the expectations hypothesis during periods when there is extreme volatility in the short term rate

financial panics the seasonality of the nominal interest rate and the founding of the fed after the founding of the fed in 1914 the frequency of financial panics and the size of the seasonal movements in nominal interest ratesboth declined substantially this paper establishes that the fed by carrying out the seasonal open market policy that eliminated the seasonal in nominal interest rates caused the decrease in the frequency of panics since seasonal movements are anticipated and financial panics are probably real events the results show that an anticipated monetary policy had real effects on the economy copyright 1986 by american economic association

responsiveness to energy price changes when salience is high residential natural gas demand in ukraine abstract despite its importance for policy purposes evidence about the price elasticity of natural gas demand in the residential sector is very limited and based on inference from situations with modest variation in prices we focus on a locale and time when price changes were extreme and salient to consumers namely ukraine between 2013 and 2017 we exploit the tariff reforms and detailed micro level household consumption records to assess whether consumers adjust their consumption in response to the rate changes and estimate the price elasticity of the demand for natural gas to isolate behavior attention is restricted to those households that made no structural energy efficiency upgrades to their homes thus keeping the stock of gas using capital fixed we find that households are capable of reducing consumption even without installing insulation or making any other structural modifications to their homes the price elasticity is about 0 16 wealthier households people living in multifamily buildings and heavy users have more inelastic demands households reduced consumption even when they received government assistance this and the fact the demand is inelastic especially for wealthier households bode well for tariffs or energy tax schemes where wealthier households subsidize the consumption of the poorer ones

the role of the federal reserve as lender of last resort and the seasonal fluctuation of interest rates the federal reserve s role as a lender of last resort may explain why the seasonal fluctuation of interest rates appeared to decline around 1914 the creation of the fed reduced the seasonal fluctuation of both the probability of a bank receiving an emergency loan and the probability of a financial panic the seasonality of real interest rates could therefore have declined regardless of whether the fed conducted seasonal open market operations the evidence is consistent with the lender of last resort model copyright 1991 by ohio state university press

the phillips curve the persistence of inflation and the lucas critique evidence from exchange rate regimes comment we present evidence from the united states and the united kingdom that the persistence of price inflation is significantly higher under managed exchange rate regimes than under gold based fixed exchange rate regimes these differences are also reflected in expectations augmented phillips curves we use a two country macro model with forward looking price setters to demonstrate that higher monetary accommodation of inflation and exchange rate accommodation of inflation differentials increase inflation persistence the evidence does not contradict this hypothesis it supports the hypothesis of forward looking price setters and highlights the empirical significance of the lucas critique jel e31 e42 f33

searching for leviathan an empirical study in several papers and a recent book geoffrey brennan and james buchanan 1977 1978 1980 have put forth a striking and controversial view of the public sector drawing by analogy on the conventional theory of monopoly in the private sector they envision a monolithic government that systematically seeks to exploit its citizenry through the maximization of the tax revenues that it extracts from the economy from this perspective they develop a fiscal constitution whose central purpose is to constrain leviathan by limiting in various ways its access to tax and other fiscal instruments while the leviathan hypothesis has been the source of lively debate and a wide range of policy proposals it has not been the subject of much systematic empirical work or testing this is a matter of some importance since the policy implications of the leviathan view are disturbing to put it mildly in particular brennan and buchanan virtually stand on their heads many of the basic theorems in public finance for an efficient and equitable tax system if in fact the leviathan view is an inaccurate depiction of the functioning of the public sector the introduction of their policy proposals is likely to make a sorry mess of the fiscal system the leviathan model does however have some straightforward implications for observable fiscal behavior it is the purpose of this paper to examine one of these testable implications brennan and buchanan stress that fiscal decentralization is itself a powerful constraint on leviathan competition among governments in the context of the interjurisdictional mobility of persons in pursuit of fiscal gains can offer partial or possibly complete substitutes for explicit fiscal constraints on the taxing power 1980 p 184 such competition among governments in a federal system that places heavy reliance on local fiscal decisions will greatly limit the capacity of leviathan to channel resources into the public sector in short as indicated by the epigraph to this paper the leviathan model implies that other things equal the size of the public sector should vary inversely with the extent of fiscal decentralization 2
