was the emergence of the international gold standard expected evidence from indian government securities abstract the emergence of the gold standard has for a long time been viewed as inevitable we analyze agents expectations using the spread between gold and silver bonds issued by the indian government we find that bimetallism was credible until france surprised markets by suspending domestic operation of bimetallism triggering a run away from silver thereafter markets began demanding a premium to hold silver bonds indicating their belief that silver would depreciate in the future as more countries moved on gold

how should commodities be taxed market structure product heterogeneity and the optimal structure of commodity taxes abstract this paper is concerned with the form in which commodity taxes are best imposed and particularly with the appropriate balance between specific and ad valorem components this neglected issue is of policy importance in relation to the harmonization of tax structures within the eec and of theoretical interest as a point of contact between optimal tax theory and models of non price competition the roles of the two taxes as purely corrective devices under a variety of market forms are established and discussed the analysis suggests that heavily taxed commodities should normally be subject to high specific rather than high ad valorem taxes

indirect taxation and undesirable competition abstract this paper studies undesirable competition in an asymmetric oligopoly under ad valorem taxation we show that when the cost advantage of efficient firms is large both the entry of and the cost reduction in efficient firms raise social welfare but unexpectedly hurt consumers moreover we find that unit taxation yields higher consumer surplus in equilibrium and it could also be welfare superior to ad valorem taxation under certain conditions

efficiency considerations and the exemption of food from sales and value added taxes we evaluate efficiency considerations underlying the widespread exemption of food from sales and value added taxes and the implications for tax policy household and restau rant meals and both constant and increasing returns cases are examined higher taxes on food offset the non taxation of time inputs into household production even under constant returns to scale with increasing returns gains from taxing food are higher and amplified by subsidizing restaurant food and all marginal cost components of restaurant meals on effi ciency grounds exemption of food from sales and value added taxes emerges as socially costly policy especially under increasing returns

the incidence of non linear price dependent consumption taxes abstract the present article generalizes economic literature on the incidence of consumption taxes to general schedules of consumption taxes dependent on price previous studies were limited to the cases of per unit and ad valorem taxes three main contributions are made methodologically the elasticity of the tax function is introduced as a new parameter so that the price elasticity of general consumption tax schedules in different models of imperfect competition might be dealt with in a tractable manner theoretically existing results on the difference between the incidence of ad valorem and per unit consumption taxes are generalized to non linear consumption taxes the larger the elasticity of the tax function the smaller the share of consumption tax borne by consumers from the perspective of applied public economics it is shown how the regulator may reduce prices in very uncompetitive markets by increasing the elasticity of the consumption tax on a targeted range of producer prices

the design of insurance coverage for medical products under imperfect competition this paper studies the design of health insurance with ex post moral hazard when there is imperfect competition in the market for the medical product various scenarios such as monopoly pricing or horizontal differentiation are considered insurers or their regulator can commit to a reimbursement policy which specifies two types of copayments an ad valoremcoinsurance rate and a specific per unit copayment by combining both copayment rates in an adequate way the insurer can effectively control the producer price which is then set so that the producer s revenue just covers fixed costs consequently a suitable regulation of the copayment instruments leads to the same reimbursement rule as under perfect competition for medical products additional rationing of coverage because of imperfect competition is notnecessary the optimal policy involves the smallest possible copayment combined with the largest possible coinsurance rate such that the participation constraint of health providers is binding

price pass through and the minimum wage this paper tests a textbook consequence of competitive markets that an industry wide increase in the price of labor is passed on to consumers through an increase in prices using several data sources on restaurant prices i explore the price impact of minimum wage hikes in canada and the united states particular attention is paid to the timing of these price responses to gauge the stickiness of minimum wage cost shocks i find that restaurant prices generally rise with changes in the wage bill and that this response is concentrated in the quarter surrounding the month during which the legislation is enacted

the comparative efficiency of ad valorem and specific taxes under monopoly and monopsony abstract it is well known that ad valorem taxes welfare dominate specific taxes under monopoly this paper demonstrates that the comparative welfare ranking of the two instruments reverses under monopsony the relative performance of alternative tax forms is thus highly sensitive to whether the buyer or seller has market power

the effects of taxation price control and government contracts in oligopoly and monopolistic competition abstract many government contracts with or policies towards oligopolistic sectors essentially involve private firms selling a given proportion or quantity of output to the government at a fixed price p r with the remainder being sold on the open market often this is combined with consumer rationing examples include cement and sugar in india and health housing and defence in many countries the paper investigates the effects of these schemes including sales and excise taxation on prices output and household welfare under oligopoly and monopolistic competition less government control reduced may raise prices and tax shifting can be above or below 100 percent

the efficiency of indirect taxes under imperfect competition abstract this paper considers the relative efficiency of ad valorem and unit taxes in imperfectly competitive markets we provide a simple proof that ad valorem taxes are welfare superior to unit taxes in the short run when production costs are identical across firms the proof covers differentiated products and a wide range of market conduct cost asymmetries strengthen the case for ad valorem taxation under cournot competition but unit taxation may be welfare superior under bertrand competition with product differentiation ad valorem taxation is superior with free entry under cournot competition but not necessarily under price competition when consumers value variety

risk sharing in licensing abstract this paper studies the design of linear license contracts under demand or cost uncertainty the optimal contract consists in general of a mix of a fixed fee and royalties the source of uncertainty has a crucial impact on the type of royalties that must be used in particular under demand uncertainty at most two of the instruments are used the contract generally combines a fixed fee with an ad valorem royalty when cost is uncertain a wider variety of cases can arise the contract may involve a combination of either type of royalties coupled with a fixed fee alternatively it may be optimal to use all three available instruments

world war ii as reflected on capital markets abstract historical events are reflected in asset prices we analyze government bond prices of five european countries traded on the swiss bourse during wwii apart from the official outbreak of wwii loss and gain of national sovereignty influenced the capital market

inflation is always and everywhere a monetary phenomenon richmond vs houston in 1864 on april 1 1864 the confederate currency reform act reduced the money supply in the eastern confederacy by one third the delayed implementation of the reform west of the mississippi provides a counterfactual view of what may have happened in the east had the reform not been enacted this episode is a natural experiment illustrating the relative importance for prices of war news vs the quantity of money in circulation our analysis of the major eastern and western gold markets richmond and houston strongly suggests that money matters more than war news in the post reform period this abstract was borrowed from another version of this item

estimating the peace dividend the impact of violence on house prices in northern ireland this article exploits data on the pattern of violence across regions and over time to estimate the impact of the peace process in northern ireland on house prices after establishing a negative correlation between killings and house prices we estimate the parameters of a markov switching model with conflict and peace as latent states we use the model to estimate the size of the peace dividend as captured in house price changes jel d74 r23 r31 conflict in ireland has a long history even after the republic of ireland was created as an independent state in 1920 the status of the mainly protestant north remained contested from the late 1960s a violent conflict flared up which claimed around 3 500 lives only more than two decades later from 1993 onwards emerged a peace process which while initially fragile culminated in a cessation of violence and a return to devolved government by 2007 the conflict was a major source of social and economic dislocation but as peace took hold this has begun to be repaired this paper assesses the impact of peace by using variation in violence within northern ireland to study one important economic aspect of the peace process and the dividend that it brought to residents of northern ireland the impact on house prices houses are assets whose prices reflect the present and future expected attrac tiveness of living in an area even during the height of the conflict in northern ireland violence was not uniform for example belfast the capital city of the province of northern ireland was particularly hard hit looking for economic consequences of the peace process we would therefore expect benefits to be concentrated among areas where violence was most prevalent we exploit within region variability in violence and house prices over time having such variation is rare in studies of the economic consequences of conflict our specific measure of violence is conflict related deaths these have been well documented by sutton 1994 and the conflict archive on the

turkey s energy efficiency assessment white certificates systems and their applicability in turkey abstract the last decade has seen an increase in the importance of energy efficiency and the sustainable use of energy resources due to their significant benefits for reducing a country s dependence on foreign energy resources and increasing awareness on environmental problems turkey aims to reduce its energy intensity by 20 up to 2023 and in order to accomplish this target the country plans to use energy more effectively in various industries and develop financial mechanisms for energy efficiency although much effort has been made to improve energy efficiency additional policies such as marked based incentives are still necessary this article deals with one of the many market based energy efficiency policies called tradable white certificates whc or energy efficiency obligations the current situation of the energy field in turkey and energy consumption by industries is presented first in this paper followed by potentials for energy efficiency in each industry and energy efficiency policies furthermore the theory and applicability of a whc system is introduced and discussed in terms of market conditions choice of obligated participants and market mechanisms and barriers for the turkish electricity and natural gas market to benefit from the residential and industrial energy savings potential

a pareto comparison of ad valorem and unit taxes in noncompetitive environments abstract a literature that began with wicksell 1896 has shown that an ad valorem tax is welfare superior to an equal yield unit tax in both monopoly and oligopoly markets this paper proves a stronger result for any unit tax imposed on a monopoly there exists an ad valorem tax that pareto dominates it that produces larger profit tax revenue and consumer surplus the paper then considers whether this pareto result generalizes to all cournot nash oligopolies the paper shows that pareto dominance holds in such markets whenever the tax level exceeds a critical value that depends on various market parameters

environmental tax in a green market we examine the impact of an emission tax in a green market characterized by consumers environmental awareness and competition between firms for both environmental quality and product prices the unique aspect of this model comes from the assumption that the cost for an increase in quality is fixed we show that the emission tax improves welfare thanks to a decline in pollution and despite an accentuation of product differentiation the higher the marginal environmental damage is the higher the optimal tax will be the optimal tax however becomes lower than the marginal damage when the market is not too large finally when marginal environmental damage is not too low the optimal tax leads to a green product monopoly

domestic tax reform and international oligopoly abstract this paper examines the strategic use of domestic tax instruments and the welfare effects of multilateral domestic tax reform in a model of international cournot oligopoly the welfare effects of commodity tax harmonization appropriately defined are precisely as in the competitive case it is always potentially pareto improving and starting from the nash equilibrium in tax rates is pareto improving without any need for compensation a mutual reduction of production subsidies benefits the efficient low marginal cost country and harms the inefficient despite the pre existing monopoly distortion the effect on global efficiency is ambiguous

welfare ranking ad valorem and specific tariffs under monopolistic competition actual trade and tariff policy prefers ad valorem tariffs to specific tariffs yet in this paper we show that in a setting of monopolistic competition realizing a given restriction on imports via a specific tariff would generate more consumer utility than obtaining the same restriction via an ad valorem tariff jel classification f12 un classement en terme de bien etre des droits de douane ad valorem et specifiques quand on est en regime de concurrence monopolistique les politiques commerciales en vigueur pref rent les droits de douane ad valorem aux droits de douane specifiques or ce memoire montre que dans un contexte de concurrence monopolistique reduire les importations par le truchement d un droit de douane specifique genere plus d utilite pour le consommateur que les memes restrictions obtenues par le truchement d un droit de douane ad valorem

are flexible taxation mechanisms effective in stabilizing fuel prices an evaluation considering wholesale fuel markets in this paper we study the incidence of specific taxes in the italian fuel markets and exploit these findings to simulate the effects of fiscal policies aimed at mitigating oil price fluctuations we estimate several reduced form specifications using as dependent variables the equilibrium wholesale prices for gasoline and motor diesel over the period 1996 2007 in particular we assess the impact on wholesale gasoline and motor diesel prices stemming from the creation of an automatic fiscal mechanism consisting of reductions in specific taxes matching the rise in oil prices our simulations suggest that flexible taxation mechanisms could not be a proper policy for stabilizing price levels in fuel markets a more effective control on prices can be obtained by focusing on the market structure of these industries where antitrust authority could play a significant role

turning points in the u s civil war views from the grayback market this paper introduces a new high frequency time series of confederate money prices taken from the newspapers of richmond and leading cities in the eastern confederacy the new grayback series is tested for turning points the empirical analysis suggests that turning points in the confederate grayback market were different from those identified in the union greenback market by willard et al 1996 it appears that war did not always have symmetric effects on northern and southern money prices jel codes n20 n40

who pays sales taxes evidence from french vat reforms 1987 1999 the point of this paper is to provide visual evidence of tax shifting and to measure empirically the distribution of the sales tax burden between consumers and producers for that purpose two french reforms are studied these reforms entail steep decreases of the vat rate september 1st 1987 the vat rate on car sales went down from the luxury rate of 33 33 to the full rate of 18 6 september 1st 1999 the vat rate on housing repair services went down from the full rate of 20 6 to the reduced rate of 5 5 the consumer share of the sales tax burden is 57 in the new car sales market and 77 in the housing repair services market

a common features analysis of amsterdam and london financial markets during the eighteenth century we examine the financial linkage between the london and amsterdam financial markets using stock prices recorded in each market over the period 1723 94 in conjunction with tests for common trends cycles and regime shifts these tests reveal a surprising degree of integration between the markets as their prices move together in both the short and long run moreover shocks to the assets translate quickly and accurately between markets it also appears that dutch investment did not destabilize london markets and stock prices in london were the primary determinant of prices in amsterdam

key drivers for unsustainable resource use categories effects and policy pointers abstract prevailing resource use patterns of the global socio industrial metabolism are unsustainable an increasing number of people globally require ever more materials including energy carriers land and water for rising living standards and lifestyles converging towards western industrialised patterns therefore these resources will continue becoming both scarcer and depleted while environmental impacts associated with their consumption e g run away climate change will continue to rise for effective resource policies drivers for such unsustainable resource use and their effects need to be better understood and mapped by means of meta analysis of more than 60 sources of relevant literature we identified a set of ten driver categories that affect unsustainable resource use inter alia prevailing consumption and production patterns use and design of infrastructure and technology underlying paradigms and world views resource prices and the level of knowledge and information of resource users cumulative effects of the drivers contribute for instance up to 30 of phosphorus loss from soil and around 30 of building energy loss globally although the data does not allow clear cut causal attribution of effects it enables the distinction between direct and indirect drivers in relation to a multi dimensional network of drivers causing unsustainable resource use resource policy should combine policy objectives and instruments into policy mixes to target key drivers and their interrelations while policy mixes need to respond to context specific driver settings targeting consumer behaviour emerges as a general driver focus of policy mixes combining different instrument types and implementing them in a time dynamic sequence can mitigate trade offs between different instruments and in the longer term increase feasibility of profound behaviour changes

gradual incorporation of information pharmaceutical stocks and the evolution of president clinton s health care reform abstract we examine the effect of the evolution of president clinton s health care reform proposal over january 1992 october 1993 on pharmaceutical stock prices we identify a 52 3 percent decline in market adjusted prices which we then associate with health care reform applying a new technique isotonic regression we find most of the decline occurred gradually much of the decline occurred as the clinton plan adopted strategies to contain health care costs including managed competition and implicit regulation indirect evidence suggests that the wealth lost by pharmaceutical companies may have been largely an anticipated transfer our results are relevant to understanding the likely effects of the clinton plan and more recent proposals many other policy changes are marked by gradual public revelation of information which may not be completely observable by a researcher our approach may uncover information about the anticipated effects of policies unavailable from a traditional event study

the comparison between ad valorem and specific taxation under imperfect competition abstract this paper compares ad valorem and specific taxation in two models of oligopoly with and without free entry predominantly ad valorem taxation implies a relatively low consumer price high tax revenue and when entry is precluded low profits ad valorem taxation dominates specific taxation from the welfare perspective the set of circumstances under which with free entry specific taxation raises welfare is a strict subset of that in which ad valorem taxation is welfare improving and in both models the maximisation of consumer welfare subject to a binding revenue constraint requires maximum reliance on ad valorem taxation

free entry and social inefficiency our goal is to provide a simple yet general exposition of the conditions under which the number of entrants in a free entry equilibrium is excessive insufficient or optimal our analysis compares the number of firms that enter a market when there is free entry with the number that would be desired by a social planner who is unable to control the behavior of firms once they are in the market that is we consider the second best problem of choosing the welfare maximizing number of firms while we take as given their noncompetitive behavior after entry we demonstrate that the crucial conditions for establishing the presence of an entry bias can be stated quite simply in terms of the outcome of the postentry game played by entrants in contrast to previous work we do not need to model this postentry game explicitly

tax incidence under imperfect competition comment abstract delipalla and o donnell 2001 contains a formula for the incidence of specific and ad valorem taxes in a conjectural variation oligopoly model with potentially asymmetric firms the formula is incorrect we derive the correct formula and provide a discussion of the error and its implications for empirical studies of pass through

welfare effects of taxation in oligopolistic markets this paper discusses how marginal costs of public funds are related to various market characteristics under imperfect competition under a quite general tax scheme these costs turn out to be lower the wider the firms product ranges the lower the degree of market concentration and the lower the degree of product differentiation moreover marginal costs of taxation are lower in bertrand markets compared to cournot markets in cases when marginal costs of public funds cannot easily be assessed we ask if pass through rates can provide useful information for policy makers the market characteristics that we analyze are shown to have opposite effects on pass through and marginal costs of public funds it is also demonstrated that the marginal cost of public funds is generally lower for ad valorem taxes than for unit taxes the main results are based on a linear demand system but a number of extensions confirm that our main results are reasonably robust

measuring tax incidence an application to mortgage provision in the uk this paper derives measures of the average and marginal incidence of a tax or subsidy in imperfect competition in the context of the uk housing market we argue that one form of mortgage common in the uk but not elsewhere the endowment mortgage exists primarily because of the structure of taxation in the uk we estimate the determinants of the choice of the type of mortgage and the size of mortgage conditional on the choice using data from the building societies association on 43 000 individual mortgages taken out between 1985 and 1989 the estimated parameters are an input to the incidence measures results suggest that between 70 and 80 of the additional subsidy to endowment mortgages is captured by lenders rather than borrowers

world war ii events and the dow jones industrial index abstract this paper investigates which events of world war ii wwii the us investors at that time considered as turning points structural breaks of the war the empirical study employs daily dow jones industrial average stock index and volatility from january 1939 to december 1945 and applies structural shift oriented test to determine endogenously the structural breaks during the wwii period results show that the majority of the wartime events on and off the battlefield labelled important by historians did result in structural breaks in both price movement and stock returns volatility risk these results have major implications for investors of the present and future

cost pass through in differentiated product markets the case of u s processed cheese in this paper we estimate a mixed logit model for demand in the u s processed cheese market the estimates are used to determine pass through rates of cost changes under different behavioral regimes we find that under collusion the pass through rates for all brands fall between 21 and 31 while under nash bertrand price competition the range of pass through rates is between 73 and 103 the mixed logit model provides a more flexible framework for studying pass through rates than the logit model since the curvature of the demand functions depends upon the empirical distribution of consumer types

seigniorage legal tender and the demand notes of 1861 i introduction shortly after the onset of hostilities at fort sumter the lincoln administration asked congress to authorize the first large scale issue of federal paper currency officially labeled as united states notes they were popularly known as the demand notes of 1861 the administration s action is unremarkable the extraordinary revenue requirements of long and costly wars are often met in part by issuing paper money more surprising and not widely recognized is that this initial issue of paper money carried provisions that largely prevented it from yielding sustainable revenue seigniorage these provisions were largely omitted for the successor currency to the 1861 notes also known as united states notes but popularly as greenbacks as a result its seigniorage potential was greater although seigniorage was limited by other provisions in modern software jargon the greenbacks might be viewed as 1861 notes version 2 0 a version better suited to sustain a flow of seigniorage however the government was unable to replace the latter with the former very quickly resulting in an extended period during which two paper currencies with different properties circulated side by side both with each other and with gold coin this somewhat untidy situation provides an interesting and heretofore underexploited experiment for economists these alternative monies circulated widely with market determined exchange rates for a substantial period during which the amounts of both paper currencies in circulation greatly increased before the 1861 notes were removed from circulation we have collected daily data on these exchange rates and report them as differing gold premiums for the competing paper monies below these data are exploited to calculate the seigniorage cost of the various provisions of the 1861 notes and to provide evidence on alternative theories of expectations formation during this period our paper has three sections the first presents a more extensive discussion than has been previously available of the 1861 notes in the second a simple analytical framework is used to demonstrate and where possible estimate the seigniorage costs of the provisions attached to these notes the third section analyzes the market relationship between gold and the simultaneously circulating 1861 notes and greenbacks prior to the all but complete retirement of the former in 1863 the paper concludes with a summary ii the demand notes of 1861 the major focus of this paper is on the demand notes of 1861 the first large scale federal experiment with paper money 1 we concentrate on these notes for two reasons first little has been written about them mitchell 1902 in his pioneering work on civil war finance devotes only 7 pages to them while devoting 17 pages to fractional currency and minor coins during the war in addition most of his discussion concerns the period prior to suspension more recently calomiris 1988a 1988b 1992 makes reference to the 1861 notes but only as a part of his discussion of greenbacks second the paradox of issuing largely seigniorage free paper money to help finance a war has not been well recognized and hence largely unexplained this conflict between means and ends is interesting in its own right and illuminates some of what is puzzling in the sequence of monetary events over the first half of the civil war as a part of our discussion of the 1861 notes we challenge or extend the existing literature in three ways first we demonstrate that the conclusion of studenski and krooss 1963 141 144 that these notes were only used by the government to pay salaries and hence in their words were a pseudomoney is mistaken examination of the financial press of the day suggests that these notes were not only popular but also circulated widely as money a convincing claim can be made that they were indeed a national currency

sovereign debt guarantees and default lessons from the uk and ireland 1920 1938 abstract we study the daily yields on irish land bonds listed on the dublin stock exchange during the years 1920 1938 we exploit irish events during the period and structural differences in land bonds to tease out a measure of investors credibility in a uk sovereign guarantee using ireland s default on intergovernmental payments in 1932 we find a premium of about 43 basis points associated with uncertainty about the uk government guarantee we discuss the economic and political forces behind the irish and uk governments decisions pertaining to the default our finding has implications for modern day proposals to issue jointly guaranteed sovereign debt further in view of all the historical circumstances it is not equitable that the irish people should be obliged to pay away these moneys eamon de valera 12 october 1932

efficiency enhancing taxation in two sided markets this paper examines the efficient provision of goods in two sided markets and characterizes optimal specific and ad valorem taxes we show that i a monopoly may have too high output compared to the social optimum ii output may be reduced by imposing negative value added taxes subsidy or positive specific taxes

are alcohol tax hikes fully passed through to prices evidence from alaska on 1 october 2002 the state of alaska increased taxes on malt beverages from 0 35 per gallon to 1 07 per gallon increased taxes on wine from 0 85 per gallon to 2 50 per gallon and increased taxes on distilled spirits from 5 60 per gallon to 12 80 per gallon the net effect is that the tax on a standard serving rose from about 3 cents for beer 2 cents for wine and 4 cents for spirits to a uniform tax of 10 cents per standard serving of each type of alcohol beverage this paper uses primary data on alcoholic beverage prices in alaska to study a very basic question what was the impact of the tax hikes on prices an alcohol tax hike is often viewed as a public health policy tool to discourage excessive alcohol consumption and alcohol related problems such as drunk driving the impact of a tax hike on alcoholic beverage prices is a key link in the chain of the causality from the tax to public health economic theory and previous empirical studies mainly of taxes on goods other than alcoholic beverages do not provide very much guidance on what to expect following a tax hike it is an empirical question to answer the question i conducted telephone surveys just before and a year after the tax hike of on premise and off premise alcohol retail establishments across alaska

the impact of political risk on the volatility of stock returns the case of canada this paper examines the impact of political risk in canada on the volatility of stock returns our results suggest that political news associated with the possible separation of quebec from canada plays an important role in the volatility of stock returns however our evidence indicates that investors do not require a risk premium supporting the idea that political risk is diversifiable we also show that stock return volatility varies with the degree of a firm s exposure to political risk namely the structure of assets and the extent of foreign involvement which indicates that firms most exposed to political risk bear the burden of diversification

tax incidence under oligopoly a comparison of policy approaches abstract this paper presents a methodological approach for the analysis of tax incidence that encompasses familiar forms of taxation in a general and analytically convenient model in oligopolistic industries the performance of a tax depends on the sensitivity of the unit tax rate to changes in industry output output elastic tax schedules are less likely to be over shifted and have superior welfare properties relative to regulatory instruments that are less responsive to the equilibrium market quantity for revenue neutral tax reforms the finding of delipalla and keen 1992 that ad valorem taxes welfare dominate specific taxes under oligopoly is derived as a special case of this general result

oligopolistic competition and economic welfare a general equilibrium analysis of entry regulation and tax subsidy schemes abstract two contributions to the general equilibrium analysis of an oligopolistic economy with free entry are intended first we generalize the excess entry theorem to the effect that a marginal decrease in the number of oligopolistic firms from the free entry equilibrium level improves economic welfare second we explore the pareto improving tax subsidy schemes in an oligopolistic economy several self financing and pareto improving tax subsidy schemes will be identified in contrast with the preceding analysis by atkinson and stiglitz which focused on the long run incidence of corporate taxation we analyse the short run as well as long run welfare implications of various policies under generalized conditions

the impact of a soda tax on prices evidence from french micro data abstractbased on an original data set of more than 500 000 non alcoholic beverage price records we evaluate the impact on consumer prices of the soda tax an excise on drinks with added sugar or sweetener introduced in france in january 2012 we adopt a difference in differences approach and find that the tax was gradually passed through to the prices of the taxed beverages after 6 months of its introduction it was fully shifted to soda prices and almost fully shifted to the prices of fruit drinks while the pass through for flavoured waters was incomplete we also find that the pass through was heterogeneous across brands and retail groups

pass through in a concentrated industry empirical evidence and regulatory implications we estimate pass through with thirty years of data from a concentrated industry the empirical model accounts for oligopoly interactions yet facilitates estimation with aggregate price data robust statistical evidence supports that industry wide cost changes are more than completely transmitted downstream and that this industry pass through is largely unaected by competitive conditions the industry in question portland cement is a major focus of environmental and antitrust regulators we use our pass through estimates to i evaluate the welfare consequences of marketbased co2 regulation ii predict the magnitude and location of price eects due to a merger under review by antitrust authorities and iii corroborate the simulation based analysis of the epa regarding its impending regulation of local pollutants

more and cheaper haircuts after vat cut on the efficiency and incidence of service sector consumption taxes abstract consumption tax rates targeted at specific sectors are often reformed without any empirical knowledge about the efficiency of these policies this paper sheds light on tax incidence as well as the efficiency issue the potential for welfare improving reform by studying the impact of value added taxes vat on prices and quantities of labor intensive services i utilize a vat reform targeted at a specific service sector which creates a natural experiment set up the vat for hairdressing services in finland was reduced from 22 to 8 and the previous tax treatment still applied to other labor intensive services the choice of the treatment and control groups was exogenous to circumstances in finland since these groups were selected from a wider european setting the results suggest that hairdressers cut their prices only by half of what a complete pass through would have implied and that there was hardly any adjustment in equilibrium quantity due to the reform hairdressers were able to increase their profits significantly there is important heterogeneity in the results according to firm size

imperfect competition the marginal cost of public funds and public goods supply abstract this paper analyses the impact of changes in product market competition on the marginal cost of public funds mcpf and public goods supply when distortionary commodity taxes are used to raise revenue first less competition measured by a switch from bertrand to cournot conduct or a decrease in the elasticity of demand does not necessarily raise the mpcf second even if it does optimal public good supply does not necessarily fall the paper also presents a method for modelling bertrand and cournot competition in general equilibrium that may be of independent interest

subsidizing and taxing business procurement abstract this paper studies the effect of a subsidy or tax on a market where a downstream manufacturer uses a competitive tender to procure inputs from upstream suppliers subsidizing input production can result in input price decreases that are greater than the effective decrease in marginal costs that is overshifting occurs when the size of the subsidy is not too large the downstream firm can enjoy an increase in profits greater than the government expenditure on the subsidy a relatively weak sufficient condition for these results to hold is that suppliers earn a positive profit margin on the marginal unit sold before taking into account any subsidy payment stronger sufficient conditions tailored to each result are provided

energy savings obligations in the uk a history of change this paper looks at energy savings obligations in the uk more specifically it discusses how the policy instrument changed over time and what the drivers of that change were the uk was the first country in europe that introduced obligations on suppliers to save energy at the customer end in 1994 since then this policy changed rapidly and is now the principal instrument to deliver energy savings in the housing stock the paper aims to answer three questions first how did the policy instrument change over time second what were the key drivers of that change third how did those pressures filter through the policy process and affect the energy savings obligations

german debt traded in london during the second world war a british perspective on hitler two series of german bonds issued in 1924 and 1930 traded on the london stock exchange throughout hitler s 1933 45 regime in germany we isolate both structural breaks and turning points in these bond series major turning points follow hider s reintroduction of conscription in 1935 the outbreak of war in 1939 and the d day invasion of june 1944 the german bonds sustained downward trend after 1935 suggests that bondholders recognized the risks posed by hitler s programme bond prices recovered during the war however and appear to have anticipated the overthrow of hitler and the postwar settlement of foreign bondholders claims german bonds even in peace time were distinctly dubious investments and the fact of war has entirely justified the distrust with which they have long been regarded

what makes the stock market jump an analysis of political risk on hong kong stock returns abstract this paper employs a components jump volatility filter to investigate the possible market impact of political risk the filter operates by identifying jump return dates which are then associated with political events allowing us to measure the market return and volatility effects of political announcements our empirical results show that political developments in hong kong have a significant impact on its market volatility and return the results have some interesting implications for option pricing and political risk management

sustainability performance for brazilian electricity power industry an assessment integrating social economic and environmental issues the increased pressure on companies to address sustainability issues has resulted in the development of several voluntary corporate sustainability integration approaches the array of existing approaches is large and overwhelming resulting in companies not understanding what corporate sustainability really means for their businesses considering environmental economic and social issues this paper aims at assessing the performance of the brazilian electricity power industry in terms of its sustainability performance an analysis of global reporting initiative gri indicators for the energy sector lead to an assessment of its sustainability performance by applying data envelopment analysis dea specified with a directional distance function ddf five scenarios were created i flexible weights ii triple bottom line iii social issues iv economic issues and v environmental issues with considering i flexibility weights almost all companies are efficient we also found a significant difference when we compared i with the other four scenarios ii iii iv and v taking into account the triple bottom line scenario ii the results indicate that companies were less efficient when compared with the flexible weights scenario i taking into account the last three scenarios iii iv and v only four companies were considered as providing top benchmarks in sustainability performance

corrective tax and subsidy policies in economies with bertrand competition abstract this paper shows how we can correct market failure due to imperfect competition by using taxes and subsidies the analysis is carried out at the general equilibrium level and the importance of objective demand curves is stressed the main conclusions are first it is possible to tax the economy back to the walrasian equilibrium by using linear taxes and subsidies second the welfare theorem holds in an imperfectly competitive economy with corrective taxes and subsidies third a competitive equilibrium can also be achieved by the use of ad valorem taxes and specific output subsidies

a review of optimal energy policy instruments on industrial energy efficiency programs rebound effects and government policies abstract industrial energy efficiency programs ieeps are defined as one of the most popular government policies that aim to reduce energy consumption in industrial energy intensive sectors in this paper we review and classify the most important academic studies that have addressed the environmental and economic aspects of ieeps using a systematic review the classification of energy policy instruments has been developed based on an analytical approach we discuss also the outputs benefits and barriers of ieeps besides a comprehensive argument about the restrictive policies on the rebound effects made after the implementation of these programs the results disclose that china usa and sweden are the most addressed countries on ieeps and their applications in this regard incentive energy policies e g voluntary agreements and subsidies have been applied more than others in the last decade furthermore most of the reviewed studies emphasize energy price reform as an effective practical policy while a few analytical methods can be seen to help policy makers determine the optimal levels of decision variables finally according to the state of the art analysis the authors provide some novel recommendations to improve the performance of ieeps using some restrictive policies on the negative impacts of rebound effects

asset market perspectives on the israeli palestinian conflict this paper locates turning points in the israeli palestinian conflict since the late 1980s using asset market data from israel and the palestinian authority pa we find that major escalations in violence such as the outbreak of the intifada in 2000 lead to significant declines in asset prices in both israel and the pa conversely major peace initiatives such as the oslo accords in 1993 and the road map plan in 2003 lead to substantial increases in asset prices on both sides of the conflict an additional novel finding is that asset markets respond positively to the success of politicians who favour a negotiated settlement to the conflict

commodity taxation and imperfect competition a note on the effects of entry abstract this paper looks at the effects of allowing the number of firms to vary in seade s model of oligopoly and taxation we show that the normative and positive consequences of a specific commodity tax are affected by entry in significant ways

tax incidence with strategic firms in the soft drink market abstract because soft drink sd consumption is considered to be a contributor to the epidemic of obesity there is a growing interest in evaluating the impact on sd consumption of alternative tax policies in this paper we propose a methodology to evaluate the impact of taxation of a food market taking into account the strategic price response of both manufacturers and retailers we apply this methodology to the french sd market and simulate the impacts of ad valorem and excise taxes we find that firms behave differently when facing an ad valorem tax or an excise tax an excise tax is overshifted to consumer prices while an ad valorem tax is undershifted to consumer prices we find that an excise tax based on the sugar content of sd is the most effective at reducing sd consumption our results also indicate that ignoring strategic pricing by firms leads to misestimations of the impact of taxation by between 15 and 40 depending on the products and the tax implemented in the short term that is ignoring positive long term health effects a 9 cents l excise tax has a small negative welfare effect about 1 person year

testing equity market efficiency around terrorist attacks this article uses the nine major bombings since 1998 that have been attributed to al qaida to examine market efficiency including a test of rumours that investors traded with advance knowledge of attacks analysis of these related but individually unexpected events confirms markets are semi strong efficient it now takes well under a trading day to fully price in a completely unexpected attack on balance markets also proved strongly efficient with no conclusive evidence of insider trading

wars and markets how bond values reflect the second world war historical events are reflected in asset prices based on a unique data set we analyse government bond prices of germany and austria traded on the swiss bourse during the second world war some war events generally considered crucial are clearly reflected in government bond prices this holds in particular for the official outbreak of the war and the loss and gain of national sovereignty other events to which historians attach great importance are not reflected in bond prices most prominently germany s capitulation in 1945 the analysis of financial markets provides a fruitful method for evaluating the importance contemporaries attached to historical events

exchange rates and casualties during the first world war abstract i estimate two factor models of swiss exchange rates during the first world war i have data for five of the primary belligerents britain france italy germany and austria hungary at the outbreak of the war these nations suspended convertibility of their currencies into gold with the promise that after the war each would restore convertibility at the old par however once convertibility was suspended the value of each currency depended on the outcome of the war from these exchange rates i extract a common trend and a common factor movements in the common trend are consistent with the quantity theory of money the common factor contains information on contemporaries expectations about the war s resolution this common factor and its innovations are correlated with time series on soldiers killed wounded and taken prisoner

the emancipation proclamation confederate expectations and the price of southern bank notes we examine the behavior of a semimonthly series of the confederate dollar price of bank notes these notes traded at par with confederate dollars from october of 1861 until november 5 1862 we use a model of the demand for two currencies to argue that this departure from par results from altered southern expectations after the 1862 congressional elections assured the enactment of the emancipation proclamation previously southerners believed a win or a negotiated settlement would allow a return to the union intact when these expectations changed bank notes appreciated against confederate dollars in addition our empirical work shows that notes appreciated following northern victories

effectiveness and effects of attempts to regulate the uk petrol industry this paper evaluates the impact that investigation and regulation of the uk petrol industry has had on the profitability of the companies using a gross margin for petrol we estimate a series of variable parameter autoregressive processes the results demonstrate that the 1979 monopolies and mergers commission investigation into the industry caused a long term decline in profit margins in the industry despite the fact that no recommendations or undertakings were made this cannot however be said for subsequent investigations

purchasing power parity under the gold standard 1 introduction long run purchasing power parity lrppp a mainstay of international economic theory has proved difficult to back up empirically many attempts have been made using various time series of data yet results continue to be mixed a standout exception to these mixed results is presented by diebold husted and rush 1991 whose work has been interpreted as very strong evidence of lrppp because of their across the board rejection of the unit root for a large sample of real exchange rates baillie 1996 p 51 cites diebold husted and rush as reestablishing purchasing power parity as a meaningful long run concept despite the substantial mixed results of other studies these mixed results are usually attributed to the power problems associated with standard unit root tests especially for small samples diebold husted and rush 1991 overcome these shortcomings by loosening the structure of the model to allow a longmemory process diebold husted and rush 1991 model real exchange rate behavior using autoregressive fractionally integrated moving average arfima models in doing so they reject the unit root for 16 real exchange rates from the gold standard era in favor of a fractionally integrated alternative hypothesis a long memory process is essentially a stationary one but where the autocorrelations take far longer to decay than the exponential rate associated with the autoregressive moving average arma class baillie 1996 p 6 this observation implies that purchasing power parity ppp holds but in some cases only in the extreme long run we agree with diebold husted and rush 1991 that the structure of standard unit root tests is overly restrictive however we offer a different solution to this problem from standard unit root tests one must conclude that either all deviations from ppp are permanent or all deviations dissipate over time however there is a third possibility that has both theoretical and empirical support unit root tests do not allow the possibility that while most deviations dissipate a few remain as permanent shocks real exchange rates may show substantial mean reversion but to a changing mean rather than to the constant ppp value this idea which we call quasi purchasing power parity qppp draws support from the balassasamuelson theory which asserts that productivity shocks can have permanent effects on real exchange rates samuelson 1994 p 202 criticizes economists who tried to use ppp as a guide even when substantive microeconomic changes had taken place between the previous putative equilibrium period and the new status quo he cites an example from the 1980s when the actual yen dollar exchange rate was 150 yen per dollar according to ppp the equilibrium exchange rate was 200 yen per dollar yet the rate proceeded to drop to 110 yen per dollar and below in qppp terms this situation would represent not a lack of mean reversion but evidence of an equilibrium that had shifted away from ppp this is a form of the penn effect whereby a rich country in comparison with a poor one will be estimated to be richer than it really is if you pretend that the simplified cassel version of purchasing power parity is correct samuelson 1994 p 201 we assert that this penn effect can occur not just between rich and poor countries but between any two countries if one of these countries is affected by a permanent external shock qppp also supports engel s 1996 p 1 proposition that the real exchange rate evolves as the sum of two processes a stationary but persistent component and a non stationary component it is generally held that while the exchange rate deviates from its long run equilibrium value in the short run it eventually converges to that equilibrium value in the long run the question then is what is that long run equilibrium value some argue it is the ppp level while others argue that there is a complex set of factors determining the long run value including such things as the relative labor productivities at home and abroad engel 1996 p

turning points in the civil war views from the greenback market in early 1862 the united states government began issuing greenbacks a legal tender currency that was not convertible into gold the government promised to redeem the greenbacks in gold eventually but speculators understood that the probability of redemption depended on union army military fortunes and political developments that affected the total cost of the war to serve the speculative interest in gold a market emerged for the purpose of trading greenbacks for gold dollars because the market price of a greenback reflected the public s perceptions of future war costs the movement of these prices provides unique insights into how people at the time perceived various events we use daily quotations of the gold price of greenbacks to identify a set of dates during the civil war that market participants regarded as turning points in some cases these dates coincide with events familiar from conventional historical accounts of the war in other instances however market participants reacted strongly to events that historians have not viewed as very significant this abstract was borrowed from another version of this item

tacit collusion and international commodity taxation the paper employs a model of dynamic price competition to study how international commodity taxation affects the stability of collusive agreements when producers in an international duopoly agree not to export into each other s home market we consider both the choice of international tax principle and the harmonization of tax rates and differentiate between a setting where production costs differ between countries and a setting where exogenous tax rate differentials are the only asymmetry the conclusions derived from this model differ strongly from those obtained under the assumption of competitive product markets

unit versus ad valorem taxes monopoly in general equilibrium abstract we show that if a monopoly sector is imbedded in a general equilibrium framework and profits are taxed at one hundred percent then unit specific taxation and ad valorem taxation are equivalent on the set of pareto optima

comparing specific and ad valorem pigouvian taxes and output quotas when the production or use of a good creates an external cost an unregulated market produces a socially inefficient quantity of output one remedy for this inefficiency is to impose a pigouvian tax equal to the marginal external damage associated with the good in many circumstances privately optimizing agents facing a pigouvian tax make decisions that are consistent with the maximization of social welfare

ad valorem platform fees indirect taxes and efficient price discrimination this article explains why platforms such as amazon and visa rely predominantly on ad valorem fees fees which increase proportionally with transaction prices it also provides a new explanation for why ad valorem sales taxes are more desirable than specific taxes the theory rests on the ability of ad valorem fees and taxes to achieve efficient price discrimination given that the value of a transaction to buyers tends to vary proportionally with the cost of the good traded

indirect taxation and cournot equilibrium we analyse a cournot model of oligopoly in an industry which is subject to indirect taxation we consider value added as well as excise taxes we allow for various types of demand and cost conditions as well as cost differences across firms as the tax is raised two types of outcomes can prevail on the one hand the net price can increase which is shown to lead to an increase in market share of high cost firms on the other hand the net price can fall in which case efficiency is rewarded in that low cost firms gain market share this latter outcome which accords with intuition will obtain in most instances it is more likely to occur i with vat rather than with an excise tax ii with concave rather than convex demand and iii with decreasing rather than increasing marginal cost finally we show that an increase in vat can lead to higher profits for low cost firms provided cost differences across firms are large enough

rockets the housing market effects of a credible terrorist threat abstract this paper explores the economic costs of conflict using a unique experiment we analyze the effects of hezbollah s massive surprise rocket attack against northern israel during the 2006 second lebanon war and the continued threat posed by the organization s expanding rocket arsenal on the housing market the labor market and patterns of migration flows and sorting relying on hedonic and repeat sales approaches and using a difference in differences identification strategy for 2000 2012 we show that the attack led to a 6 7 decline in house prices and rents in the most severely hit localities relative to other localities in northern israel these effects persisted until 2012 suggesting that the public continued to view the rocket threat as credible in contrast we find practically no effect on labor market conditions migration flows and sorting
