environmental regulation and u s economic growth in this article we quantify the costs of pollution controls by reporting the results of simulations of the growth of the u s economy with and without regulation for this purpose we have constructed a detailed model of the economy that includes the determinants of long term growth we have also analyzed the interaction between industries in order to capture the full repercussions of environmental regulations however we have not attempted to assess the benefits resulting from a cleaner environment we find that pollution abatement has emerged as a major claimant on the resources of the u s economy the cost of emission controls is more than 10 of the total cost of government purchases of goods and services

the impact of the eu emissions trading system on low carbon technological change the empirical evidence abstract this paper reviews the empirical literature analysing the effects of the eu emissions trading system eu ets on low carbon technological change the emerging evidence is assessed with references to both relevant economic concepts and the evolving regulation of the eu ets through the years the two most robust indications of the literature are a free allocation grandfathering tended to hamper low carbon investments in phases i 2005 2007 and ii 2008 2012 and b the eu ets appears to have been relatively more effective in stimulating innovation of low carbon technologies than their adoption importantly however a complete general picture of the impact of the eu ets on low carbon technological change is missing the main gap regards the lack of empirical evidence for phase iii 2013 2020 especially econometric studies are only few due to the lack of suitable databases accessible to researchers a problem that the relevant public authorities are urged to address thanks to the recent reforms of the eu ets the incentives for innovation and adoption of low carbon technologies are probably stronger today than ever before

total factor carbon emission performance of the chinese transportation industry a bootstrapped non radial malmquist index analysis this paper proposes a non radial malmquist co2 emission performance index nmcpi for measuring dynamic changes in total factor co2 emission performance over time this index enables the consideration of non radial slacks in the conventional malmquist co2 emission index mcpi the nmcpi is calculated based on a non radial directional distance function derived by several data envelopment analysis dea models furthermore nmcpi could be decomposed into an efficiency change ec index and technological change tc index a bootstrapping approach is conducted to introduce statistical inferences into the nmcpi and its decompositions based on the proposed indices the dynamic co2 emission performance change and its decompositions of the chinese regional transportation industry from 2002 to 2010 are investigated the empirical results demonstrate that the total factor carbon emission performance of the transportation industry as a whole decreased by 32 8 over the period and this reduction was primarily caused by technological decline

taxing variable cost environmental regulation as industrial policy abstract conventional wisdom has it that a country that enacts strict environmental regulations will place its firms at a competitive disadvantage this view has been challenged recently some commentators argue that stricter regulation will enhance domestic competitiveness strict regulations induce innovation we evaluate this argument in a strategic trade model in very special cases a strengthening of regulation may result in a shift of profits from foreign to domestic firms this is not a general result however environmental regulation should of course be imposed to control externalities but it is unlikely that it will serve to generate industrial advantage

an economic model of representative democracy this paper develops an approach to the study of democratic policy making where politicians are selected by the people from those citizens who present themselves as candidates for public office the approach has a number of attractive features first it is a conceptualization of a pure form of representative democracy in which government is by as well as of the people second the model is analytically tractable being able to handle multidimensional issue and policy spaces very naturally third it provides a vehicle for answering normative questions about the performance of representative democracy

social cost of environmental quality regulations a general equilibrium analysis the use of cost benefit analysis by federal regulatory agencies has expanded greatly in scope and sophistication unfortunately agencies continue to employ private cost rather than social cost to evaluate environmental quality regulations furthermore general equilibrium impacts and intertemporal effects of regulations are typically not included in the evaluation in this paper we estimate the social cost of environmental quality regulations mandated by the clean air and clean water acts we construct an econometric general equilibrium model of the united states to demonstrate that social cost estimates diverge sharply from private cost estimates we also demonstrate that general equilibrium impacts are significant and pervasive and that intertemporal effects of the regulations heretofore ignored are significant

the relevance of science and technology indicators the case of pulp and paper this paper is based on a detailed analysis of knowledge formation and technical development within pulp and paper p p technology in section two it is shown that aggregated published statistics are not reliable for a deeper understanding of r d activities in p p technology the third section contains an in depth study of the development of thermopulp technology an incremental innovation creating a more energy efficient process for thermomechanical pulping it is shown that only some 20 of total development costs are accounted for as r d in the fourth section it is argued that project groups responsible for ventures like the recently installed paper machine in braviken sweden in fact carry out important innovative activities characteristic for this technological system the innovativeness of these concentrations of engineers is not accounted for as r d the long term potential for p p technology is probably related to the ability of the actors to transform products and processes to a more intensive use of biotechnology this transformation process may be classified as a radical technological change or even a shift of technological paradigm the dominant science and technology s t indicators do not capture this process however the conclusion formulated in section six is that the dominant s t indicators provide us with very blunt tools for understanding and explaining industrial and technological change

party politics governors and economic policy in this article we evaluate the role of elections in governors state tax policy making does it matter for state taxes whether the governor is a democrat or republican and whether she is eligible for re election or faces a binding term limit using a regression discontinuity design and a panel of u s states we find that the manner in which governors of different parties implement different tax policies turns crucially on the incumbent s eligibility for re election re electable democratic governors increase income taxes relative to similarly situated republicans yielding divergence between party policy positions however governors facing a binding term limit exhibit the reverse policy difference resulting in a movement of policy back together

inter industry technology flows in the united states abstract this paper presents for the u s economy a technology flows matrix tracing 1974 industrial r d expenditures from their industries of origin to industries in which the use of resulting products and processes was anticipated the distinction between origin and using industries is crucial to understanding the links between r d and productivity growth a regression analysis reveals high social rates of return and substantial productivity impacts from r d attributed to industries of use

sectoral patterns of technical change towards a taxonomy and a theory abstract the purpose of the paper is to describe and explain sectoral patterns of technical change as revealed by data on about 2000 significant innovations in britain since 1945 most technological knowledge turns out not to be information that is generally applicable and easily reproducible but specific to firms and applications cumulative in development and varied amongst sectors in source and direction innovating firms principally in electronics and chemicals are relatively big and they develop innovations over a wide range of specific product groups within their principal sector but relatively few outside firms principally in mechanical and instrument engineering are relatively small and specialised and they exist in symbiosis with large firms in scale intensive sectors like metal manufacture and vehicles who make a significant contribution to their own process technology in textile firms on the other hand most process innovations come from suppliers these characteristics and variations can be classified in a three part taxonomy based on firms 1 supplier dominated 2 production intensive 3 science based they can be explained by sources of technology requirements of users and possibilities for appropriation this explanation has implications for our understanding of the sources and directions of technical change firms diversification behaviour the dynamic relationship between technology and industrial structure and the formation of technological skills and advantages at the level of the firm the region and the country

the impact of chinese carbon emission trading scheme ets on low carbon energy lce investment china is planning to introduce emission trading scheme ets to decrease co2 emission as low carbon energy lce will play a pivotal role in reducing co2 emissions our paper is to assess the extent and the conditions under which a carbon ets can deliver lce investment in china we chose wind technology as a case study and a real option based model was built to explore the impact of a number of variables and design features on investment decisions e g carbon and electricity price carbon market risk carbon price floor and ceiling and on grid ratio we compute critical values of these variables and features and explore trade offs among them according to our work a carbon ets has a significant effect on wind power plant investment although it cannot support investment in wind power on its own carbon price stabilization mechanisms such as carbon price floor can significantly improve the effect of carbon ets but the critical floor to support investment is still much higher than the carbon price in china pilot etss our results show that other policy measures will be needed to promote low carbon energy development in china

information and strategic political polarisation we develop a model of electoral competition in which two opportunistic candidates select their policy position and invest in quality policy positions are observed and during the campaign the press reveals some information about quality we demonstrate that when information is imperfect the blackdowns median voter theorem fails to hold for intermediate information levels the unique equilibrium is such that candidates propose policies different from the median voter s bliss point by contrast convergence to the median occurs when quality is almost always or almost never revealed we also show that a profit maximising press may collect more information than socially optimal during the 1995 electoral campaign in belgium the vld a traditionally right wing

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource productivity

the case for responsible parties electoral platform convergence is perceived unfavorably by both the popular press and many academic scholars arguably to paraphrase it does not provide enough choice between candidates this article provides a formal account of the perceived negative effects of platform convergence we show that when parties do not know voters preferences precisely all voters ex ante prefer some platform divergence to convergence at the ex ante median after characterizing the unique symmetric equilibrium of competition between responsible policy motivated parties we conclude that all voters ex ante prefer responsible parties to opportunistic purely office motivated ones when parties are sufficiently ideologically polarized that platforms diverge but not so polarized that they diverge excessively however greater polarization increases the scope for office benefits as an instrument for institutional design we calculate the socially optimal level of platform divergence and show that office benefits can be used to achieve this first best outcome if parties are sufficiently ideologically polarized

assessing whether corporate social responsibility influence corporate value abstractthis study used the corporate social responsibility csr index to gauge the corporate value and social responsibility performance of corporations in taiwan we investigated whether csr influences corporate value and whether the extent of that influence varies with corporate value or time the results indicate that the influence of csr on corporate value does not change with time csr exerts a positive influence on company value and this influence does not change over time however the extent of the influence significantly varies with corporate value when the corporate value of a company is not high investing in csr would only increase costs and fail to effectively increase corporate value in contrast if the corporate value of the company is high investments in csr in this circumstance would instead promote the effective increase of corporate value

model of efficient and sustainable improvements in a lean production system through processes of environmental innovation abstract globalization has changed the world as well as how a customer judges the value of a product which has created a new business focus different approaches have been oriented on this direction such as the lean manufacturing system and the concept of sustainability however these two notions are not easy to implement simultaneously besides several authors have declared doubts with respect to reaching this target difficulty persists in identifying the tools required and quantifying the improvements achieved this research develops a general approach based on environmental innovation to help firms harmonize efficiency and sustainability the goal is to add extra value to the product which provides the potential to enhance competitiveness in the 21st century globalized market a case study demonstrates that the costs the incomes the social responsibility and the sustainability can be improved when environmental innovation is applied transforming the traditional production system into a lean system

almost efficient information transmission in elections abstract we study a model in which two parties compete by announcing their policies after receiving conditionally independent private signals about the true state of the world parties are both office and policy motivated our model can explain radically different policy positions even when parties receive identical signals and have unbiased preferences this holds in an asymmetric equilibrium in which both parties reveal their private information to the voters and the implemented policy is almost first best for all possible realizations of parties signals in this equilibrium one party adopts extreme and the other one moderate policy positions

the effect of implicit contracts on the movement of wages over the business cycle evidence from micro data in this paper we address the question of whether wages are affected by labor market conditions in a manner more consistent with a contract approach than with a standard spot market model from a simple implicit contract model we derive implications about the links between wages and past labor market conditions using individual data from the current population survey and the panel study of income dynamics we find that an implicit contract model with costless mobility describes these links better than either a simple spot market model or an implicit contract model with costly mobility

the effects of implicit contracts on wages evidence from the japanese labor market abstract this paper tests whether wages in japan s labor market are determined by current or past labor market conditions the empirical results are consistent with a model suggesting that labor market mobility may be limited and costly in japan for men

elections with platform and valence competition abstract we study a game in which candidates first choose platforms and then invest in costly valences e g engage in campaign spending the marginal return to valence depends on platform polarization the closer platforms are the more valence affects the election outcome consequently candidates without policy preferences choose divergent platforms to soften valence competition moreover exogenous increases in incentives for valence accumulation lead to both increased valence and increased polarization the latter because candidates seek to avoid the costs of extra valence as a result the increase in valence is smaller than it would have been with exogenous platforms finally the model highlights the overlooked substantive importance of common modeling assumptions changing the source of uncertainty in our model from noise around the median voter s ideal point to a shock to one candidate s valence as is common in the literature leads to complete platform convergence for all parameter values

business perspective to the national greenhouse gases emissions trading scheme a survey of cement companies in china abstract applying data gathered from 105 cement companies this paper gives an analysis of how business views the upcoming national greenhouse gases emissions trading scheme in china despite a good overall understanding the surveyed companies have not been able to prepare properly for the implementation of this policy they still need training to enhance their related capacity probably due to strict competition it is difficult for cement companies to pass the policy cost on to their clients the sampled companies intend to make self mitigation efforts for compliance it is highly likely that cement companies would mitigate emissions themselves if the carbon price is higher than 108 of the self abatement cost the surveyed cement companies anticipate an increase in the carbon price in china from about 35 yuan t co2 in 2020 to 60 yuan t co2 in 2025 and 90 yuan t co2 by 2030 the analysis provides reference for the smooth introduction and effective implementation of national carbon market in china from the business viewpoint

wages implicit contracts and the business cyle evidence from canadian micro data evidence of macroeconomic conditions impacting the earnings of men in canada in a manner consistent with an implicit contracting framework is found using data from eleven cross sectional surveys spanning the years 1981 1992 the estimates are similar to those found by beaudry and dinardo 1991 using u s data their analysis is extended to incestigate whether the effects of macroeconomic conditions differ by age evidence is found that the wages of young men and men near retirement are most sensitive to changes in the macroeconomic conditions over their job tenure this abstract was borrowed from another version of this item

flip flopping ideological adjustment costs in the united states senate models of electoral competition in which candidates can change position at no cost predict the convergence of platforms in a two candidate election such convergence is at odds with empirical observation in this paper i undertake a study of candidate positioning in the united states senate and determine the extent to which electoral costs associated with changing position explain the ideological positions taken by senators using over 50 years of roll call voting data i use a simulated method of moments approach to estimate a dynamic model of candidate positioning for u s senators the ndings support a model in which senators face convex costs to changing position with the best tting model being one with linear costs of adjustment the model thus predicts severe punishments for ip opping senators those who make large changes in position as a result of the signi cant costs associated with adjusting position the empirical validity of the median voter theorem which depends upon candidates being able to change position at no cost is called into question

the presidential politics of climate discourse energy frames policy and political tactics from the 2016 primaries in the united states this study presents the results of an investigation into the frequency in which four candidates of the 2016 united states presidential primary season communicated their political positions on climate change and how they subsequently framed these stances in numerous contextual drivers alongside energy policies a systematic content analysis of political debates campaign speeches and press statements reveals how hillary clinton bernie sanders donald trump and ted cruz undertook in vote seeking behaviour to create distinct stances on energy and climate issues results indicate not only partisan polarization but also that stakeholder dynamics control of communications and communication frequency are inter dependent and reinforcing in generating differing climate positions institutional dynamics exacerbate these logic schisms rather than providing a means of collective decision making we test such climate discourse according to a typology of scientific economic national security and moral frames we also assess how particular frames morph over time and are impacted by exogenous factors such as global climate change negotiations national environmental crises such as the flint water crisis and contestation over stranded assets and fossil fuel divestment we find that political climate discourse must communicate to collective bipartisan interests whilst avoiding politically divisive climate frames

environmental regulation a value theoretic and class based analysis following a value theoretic and class based approach it is argued in this paper that ecological problems are inseparably linked to the process of extracting surplus value in capitalism and owing to their adverse impacts instigate struggles over the appropriation of nature these struggles fought within and outside the state by competing agents shape environmental regulation in particular taxes permits command and control measures and subsidies affect prices profits and rents and have class and other social implications evidence of current environmental regulation shows that it takes places under the great influence of capitalist concerns

the cost of regulation osha epa and the productivity slowdown the slowdown in productivity growth in the u s economy during the 1970 s has been a matter of great concern to policymakers associated as it is with inflation unemployment and declining real wage growth this paper examines the impact on productivity growth of government regulation specifically worker health and safety regulation by the occupational safety and health administration osha and environmental regulation by the environmental protection agency epa looking at data for 450 manufacturing industries between 1958 and 1978 the study finds a large negative relationship between such regulation and productivity growth using these results about 30 percent of the decline in productivity growth in manufacturing during the 1970 s may be attributed to such regulation several previous studies have looked at the contribution of regulation to the productivity slowdown many of these have inferred that the contribution must be small on the basis of the relatively small amount spent on complying with such regulations edward denison 1979 estimates that only about 16 percent of the productivity slowdown in the 1972 75 period was due to regulation 35 percentage points out of a slowdown of 2 17 percentage points paul portney 1981 notes that little of gnp is spent on pollution control under 2 percent concluding that therefore pollution regulations could have little effect on productivity growth norsworthy et al 1979 also find a small impact of pollution abatement capital expenditures on productivity growth studies based on econometric estimation of the regulation productivity relationship have found a wide range of results gregory christainsen and robert haveman 1981 find regulation reduced labor productivity growth by 27 percentage points using time series data and measures of total federal regulation robert crandall 1981 finds a strong relationship between pollution abatement capital and productivity growth but this relationship disappears when a measure of energy intensity is included robin siegel 1979 observes a significant contribution 5 percentage points from pollution control expenditures to the productivity slowdown for 1965 73 but not for later years finally frank gollop and mark roberts 1983 examine data for a set of electric utilities and find that regulation of emissions had a large impact on total factor productivity growth lowering it for regulated firms by 59 percentage points many other factors might help to explain the productivity slowdown including the rise in energy prices the long and severe recession and declines in research and development expenditures there have been a variety of studies examining the contributions of each factor to the slowdown they generally conclude that many factors contributed to the slowdown but that a sizable fraction of the slowdown remains unexplained by the estimated contributions of all the factors considered

extended producer responsibility instruments and innovation in eco design an exploration through a simulation model abstract this paper presents an agent based simulation model that models both economical and physical relations between firms recyclers and consumers this framework allows an investigation into the connection between physical environmental variables waste flows virgin material flows and economic decisions of agents in the product chain i e firms innovation strategies consumers choices and development of recycling activities the paper highlights the value of using agent based modeling as an operational tool to investigate the effect of waste prevention policy on economic and technological decisions of agents we focus on three types of extended producer responsibility epr instruments which are recycling fees tax subsidy and norms the simulation results show that the impact of each instrument depends on the policy design in particular on the level of stringency and on the reward system which is implemented we show that only tax subsidy systems and stringent norms can lead to radical innovations and to significant changes in product designs in the case of tax subsidy the impact relies more on an innovation effect while in the case of norm it mainly relies on a selection effect

macro economic and development indexes and iso14001 certificates a cross national analysis abstract environmental management systems emss implemented according to the iso14001 standard have been examined by many authors especially focussing on its impact at the firm level however only a few papers have investigated the impact of iso14001 from a country perspective this paper aims to contribute to bridging this gap the aim is to study the relation between iso14001 growth and the trend in selected macro economic and development indexes by applying the growth mixture model to a panel of 73 countries for the period 1999 2012 we assess the following hypotheses a the increase in numbers of iso14001 certifications corresponds to an increase in economic indexes b the increase in iso14001 corresponds to an increase in development indexes c the trends of iso14001 adoption and macro economic indexes confirm the relationship described by the environmental kuznets curve the results confirm a positive relation among the trends of some variables such as iso14001 and gross domestic product gdp iso14001 and industry value added while no significant results were found when observing the relation between iso14001 and the selected development indexes in addition using the industry added value as the variable to measure economic development our results support the theory of the environmental kuznets curve

signaling character in electoral competition we study a one dimensional hotelling downs model of electoral competition with the following innovation a fraction of candidates have character and are exogenously committed to a campaign platform this is unobservable to voters character is desirable and a voter s utility is a convex combination of standard policy preferences and her assessment of a candidate s character this structure induces a signaling game between strategic candidates and voters since a policy platform affects voters utilities not only directly but also indirectly through inferences about a candidate s character the model generates a number of predictions starting with a failure of the median voter theorem jel d72 d82

the limited effect of eu emissions trading on corporate climate strategies comparison of a swedish and a norwegian pulp and paper company this article article examines to what extent and how the eu ets has influenced the climate strategies of two nordic pulp and paper companies swedish sca and norwegian norske skog rising electricity prices are perceived to be the greatest effect of the scheme the eu ets has served to reinforce commitments to improve energy efficiency and reduce co2 emissions in both companies studied procedures like monitoring of co2 emissions and accounting for co2 prices have become more significant since the introduction of the eu ets but the scheme has not triggered a search for innovative low carbon solutions due to differences in market factors and production factors sca has been more active than norske skog in investing in and implementing co2 lean actions future studies of climate mitigation activities strategies and innovations in the pulp and paper industry should involve more in depth investigation of the interactions between such factors and the eu ets c 2013 elsevier ltd all rights reserved less

the effect of implicit contracts on the movement of wages over the business cycle evidence from the national longitudinal surveys a 1991 study by paul beaudry and john dinardo found evidence of internal labor markets that augment incumbent workers wages when the external labor market is tight when unemployment is low and shield their wages when it is slack current wages they found depend on the tightest labor market conditions observed since a worker was hired not current labor market tightness or labor market tightness at the time of hiring this paper replicates and extends that research using data from six cohorts of the national longitudinal surveys that together span more than three decades as well as an estimation framework more robust than that in the original study the author finds strong support for beaudry and dinardo s key prediction supplementary regressions confirm other implications of the theory as well recently at least the effect of implicit contracting on wages has been similar for men and women

campaign advertising and voter welfare this paper investigates the role of campaign advertising and the opportunity of legal restrictions on it an electoral race is modeled as a signalling game with three classes of players many voters two candidates and one interest group the group has non verifiable insider information on the candidates quality and on the basis of this information offers a contribution to each candidate in exchange for a favorable policy position candidates spend the contributions they receive on non directly informative advertising this paper shows that 1 a separating equilibrium exists in which the group contributes to a candidate only if the insider information about that candidate is positive 2 although voters are fully rational a ban on campaign advertising can be welfare improving and 3 split contributions may arise in equilibrium and if they arise too often they are detrimental to voters

candidate strategies in primaries and general elections with candidates of heterogeneous quality abstract i consider a model in which candidates of differing quality must win a primary election to compete in the general election i show that there is an equilibrium in which democrats choose liberal policies and republicans choose conservative policies but higher quality candidates choose more moderate policies than lower quality candidates in this equilibrium higher quality candidates choose more moderate policies if they have a larger quality advantage or there is less uncertainty about the median voter s ideal point in the general election and the candidates in a given primary choose closer policies to one another when there is a smaller quality difference between the candidates in a primary i further show that if the candidates have policy motivations then a low quality candidate may strategically choose to enter a primary even if running for office is costly and the candidate will lose the primary election with certainty in equilibrium

international investment location decisions abstract in international location tournaments governments compete for foreign investment with tax and other short run incentives such tournaments can be won if agglomeration economies are sufficiently powerful to overcome investors desire to spread investments as a hedge against risk we focus on manufacturing investments by u s multinationals in the 1980s our econometric results suggest that agglomeration economies are indeed the dominant influence on investor calculations paradoxically short run incentives have limited apparent impact on location choice we conclude that high cost tournament play is unnecessary for countries with good infrastructure development specialized input suppliers and an expanding domestic market

campaign spending with office seeking politicians rational voters and multiple lobbies abstract i introduce a microfounded model of campaign finance with office seeking politicians a continuum of voters and a large number of heterogeneous lobbies lobbies make contributions to politicians according to a common agency framework politicians use contributions to finance their electoral expenditures voters are not fooled by electoral expenditures they are influenced in a way that is consistent with the equilibrium behavior of lobbies and politicians the model is used to i determine the relation between campaign spending and the deviation from the median voter s preferred policy ii show the informational value of lobbies contributions iii evaluate the welfare implications of restricting campaign spending and iv interpret the empirical finding that campaign expenditures have a very low effect on election outcome although in equilibrium advertising provides voters with useful information under reasonable parameter values a ban on campaign contributions makes the median voter better off journal of economic literature classification numbers d72 d82 m37

a model of political competition with citizen candidates the authors develop a model of electoral competition in which citizens choose whether or not to run as candidates a winner implements her favorite policy the equilibrium number of candidates depends negatively on the cost of running and positively on the benefits of winning for some parameter values all equilibria under plurality rule have exactly two candidates whose positions are distinct two candidate elections are more likely under plurality rule than under a runoff system the candidates positions are less differentiated under a runoff system there exist equilibria under both systems in which some candidates have no chance of winning

flip flopping from primaries to general elections abstract i consider a model in which candidates must win a primary election to compete in the general election candidates may choose different policies in the primary and the general election but doing so results in accusations of flip flopping i show that candidates adopt extreme policies in the primaries but then try to move closer to the center for the general election even though primary voters are forward looking and anticipate this policy moderation the extent to which candidates move closer to the center is constrained by flip flopping costs and candidates choose divergent policies in the general election i obtain comparative statics results on candidate policy choices in terms of voter preferences
