the pricing and performance of leveraged exchange traded funds abstract leveraged etfs are a recent and very successful financial innovation they provide daily returns that are in a multiple or a negative multiple of the daily returns on a market benchmark in this paper we examine the characteristics trading statistics pricing efficiency and tracking errors of a sample of leveraged etfs we find that these etfs are traded mainly by retail traders with very short holding periods price deviations from nav are small on average but large premiums and discounts are prone to occur more interestingly the behavior of premiums is different between bull i e those with a positive multiple and bear etfs i e those with a negative multiple our findings are consistent with the argument that the end of day rebalancing of the funds exposures increases market volatility at the close of a trading day as for tracking errors they are small for holding periods of up to a week but become increasingly larger for longer horizons

the backward incidence of pollution control a dual approach abstract the backward incidence of pollution control is reexamined using the techniques of duality theory the simple geometry used establishes the results and clarifies them without the complicated mathematical manipulations required in earlier works thereby making the material more attractive for classroom presentation

trade and factor movements with three factors and two goods abstract with three factors and two goods there are two extreme and one middle factor regardless of technical complementaries in the individual production functions the extreme factors must be enemies and the middle factor the other factor s friend with constant product prices

backward incidence of pollution damage compensation policy abstract the backward incidence of higher rates of compensation paid for damage on a factor of production is examined in a two sector three factor model with a linear pollution damage function on labour endowment the results implied by the stolper samuelson theorem are obtained with a consequent decrease in pollution and national income provided that the polluting and nonpolluting sectors are respectively intense in capital and labour and the complement relation between pollution and labour are assumed a geometric interpretation of the results is also provided

environmental regulation capital output and energy efficiency in china an empirical research based on integrated energy prices abstract how to improve environmental quality and achieve high quality development of economy have become important challenges for china in the new era based on the klems framework this paper analyzes the relationship between environmental regulation factor substitution and energy saving effect by using panel structure vector autoregression model and panel data of china industry from 2004 to 2014 the following conclusions are drawn 1 china s environmental regulation can promote the substitution of capital to energy however benefit of this substitution in the long run is greater than that in the short run 2 only in the long run can china s environmental regulations have significant energy saving effect technological innovation is the main reason for the improvement of energy saving effect of environmental regulation 3 china s environmental regulation will not significantly improve the structure of capital which makes the economic benefits low finally the paper discusses the possible ways to improve china s environmental regulation from the aspects of forming a scientific environmental supervision system improving energy pricing mechanism and capital structure

factor price convergence in the late nineteenth century the authors examine a dramatic historical episode of factor price convergence in the late nineteenth century their focus is convergence between old world and new and the analysis centers on land and labor wage rental ratios boomed in the old world and collapsed in the new moving the resource rich labor scarce new world closer to the resource scarce labor abundant old world the authors use econometrics and simulations to identify proconvergence forces which include commodity price convergence factor accumulation and factor saving biases the results confirm that open economy characteristics and international market integration are important sources of convergence copyright 1996 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

income inequality and international migration the purpose of this paper is to analyse the impact of international factor movements on the personal distribution of income in order to get clearcut results we use a simple model of trade and migration in which there are two traded goods and three factors for any given country one of the traded goods corresponds to exports and the other to imports the three factors include capital and two types of labour skilled and unskilled we focus mainly on the alternative results of international migration of the two types of labour the geographical focus is worldwide excerpt

liquidity risk and exchange traded fund returns variances and tracking errors abstract we investigate the effect of exchange traded fund etf liquidity on etf tracking errors returns and volatility in the us we find that illiquid etfs have large tracking errors the effect is more pronounced when underlying assets are less liquid returns and liquidity of illiquid etfs are more sensitive to underlying index returns or etf market liquidity or both thus a positive liquidity premium exists in us etf markets the etf variance could be larger than its net asst value variance owing to infrequent trading in summary illiquid etfs are more likely to deviate from their underlying indexes and could be riskier than underlying portfolios

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

investment performance of shorted leveraged etf pairs abstractwe analyze investment strategies involving triple leveraged and inverse triple leveraged etf pairs by simulating daily returns over a 48 year period our results show that many such strategies significantly outperform the s p 500 on a risk adjusted basis for example when shorting the bear triple leveraged etf and the bull triple leveraged etf in a 2 1 proportion while going long treasuries we find that the average annual sharpe ratio is more than four times higher than for the s p 500 and that the strategy outperforms the s p 500 in 43 of the 48 years our results are robust to variations in bear bull proportions rebalance thresholds and underlying parameters

do leveraged exchange traded products deliver their stated multiples abstract using the longest history of a u s equity market index this paper simulates the return deviation and multiple deviation for leveraged exchange traded products letps with different rebalancing frequencies including daily monthly annually and every five years over various holding periods we find that the general perception that daily rebalanced letps are not suitable for long term strategies is not substantiated advancing the analysis we construct a comprehensive framework that determines the deviation of an letp s effective multiple from its stated product multiple under various rebalancing frequencies and holding period scenarios the empirical framework and results from this paper hold the promise of guiding regulators policy makers and investors in their understanding of the tracking performance of letps

international labor flows and national wages when income levels of some group in the economy fall behind those of others the blame frequently is cast on the nature of international trading relationships such has been the case recently in the united states with the struggle to maintain real wages for relatively lessskilled workers much of the debate has asked how changes in world prices or in technology at home or abroad have altered wage rates see e g susan collins 1996 jones and engerman 1996 in this note we focus on another potential culprit immigration and probe more widely into past historical experience in the united states and other countries when inflows of labor from abroad disturb wage rates for nationals such international labor flows could serve to enhance rather than to depress the earnings of the country s own laborers if the question addressed concerns the effects of immigration on the welfare of the original inhabitants of a country a disarmingly simple answer was provided some years ago by harry johnson 1967 as long as immigrants bring an accumulated bundle of labor and physical or human capital that is different from that possessed by local residents the latter must gain from immigration this is the basic gains from trade argument appropriate only if the country originally did not engage in any other form of trade and if all residents held balanced portfolios of capital and labor as well it ignores the social costs incurred and extra taxes collected when migrants flow into a country in this note we focus not on aggregate welfare effects but on the effect of immigration on the return to some homogeneous national group of laborers this question is the one that most sharply divides the views of labor economists from those of trade economists on the one hand increases in the supply of labor would seem naturally to depress the return to labor but in the basic heckscher ohlin trade model with two factors and two produced commodities an inflow of labor can be absorbed with absolutely no change in wage rates as long as the terms of trade remain undisturbed we begin by asking what some basic theoretical models tell us about this issue before turning to the historical record simple theory reveals that there are two basic attributes of immigration that affect income distribution relatively how substitutable immigrant labor is for the national labor force and the occupations in which immigrants are allowed to work

trade and the distribution of economic well being in an economy with local public goods abstract this paper models a small open economy containing many identical communities and two types of workers who are perfectly mobile across communities but not internationally competitive firms produce two tradable private goods and local governments provide residents with a single public good trade patterns differ across communities in equilibrium this observation is used to prove a modified version of the stolper samuelson theorem simply stated workers who are relatively concentrated in those communities that export a given good gain from a rise in the relative price of this good whereas the other workers lose

unemployment and the backward incidence of pollution control abstract this paper reexamines the backward incidence of pollution control using duality theory for a two sector general equilibrium model in which the economy experiences large scale unemployment and perfect capital mobility with a sector specific rigid wage in the polluting sector in this context it is shown that with stricter pollution controls the wage rate in the nonpolluting sector rises while the common rental rate falls in addition stricter pollution controls are shown to have an uncertain impact on national income

factor trade and goods trade world equilibria with trade in both goods and some factors are studied when international factor endowment differences are the cause of trade a generalized heckscher ohlin theorem is presented the goods trade patterns with and without factor trade are compared factor trade and goods trade tend to be substitutes complements if traded and non traded factors are cooperative non cooperative

factor intensities and factor substitution in general equilibrium abstract this article examines how factor intensity rankings between industries and the economy wide asymmetry in the degree of factor substitution combine to influence the manner in which changes in relative commodity prices affect the factoral distribution of income the reciprocal influence of factor endowment changes on the composition of outputs is also discussed the analysis is undertaken in a general three factor two commodity framework the minimal sized model that allows both influences to affect factor prices and admits of the possibility of complementarity between factors factors which are good substitutes find their returns behave somewhat similarly when commodity prices change while factors which are complements experience strongly asymmetrical fortunes a crucial role is played by a comparison of the share of the middle factor in each sector

the evolution of dutch environmental policy the changing ecological arena from 1970 2000 and beyond abstract dutch environmental policies over the past thirty years have expanded through three distinct phases these policies gradually opened up to engage stakeholders in establishing legislation formulating implementation plans and finally jointly defining ecological objectives environmental policies became increasingly effective by ensuring the taking on of environmental responsibilities by a growing number of stakeholders four unresolved issues present a formidable agenda for environmental policy attention in the next decade managing co 2 emissions controlling future infrastructure development minimising resources use and reducing the burden on biodiversity these issues relate to the necessary management of stocks of energy other non renewable resources space and biodiversity respectively up to now the issue of the preservation of stocks has not received much policy attention they are expected to become the new policy issues complementing the traditional emission reduction policies which mainly aim at safeguarding the quality of air water and soil it is argued that super optimizing policies engaging jointly economic social and ecological interests are needed to resolve the issues at stake

free trade and income redistribution in a three factor model of the u s economy the move toward free trade promises to alter the distribution of income in the u s labor groups generally do not favor the move toward free trade which can be characterized by the continuing decline in the price of manufactured goods relative to business services the present study predicts that unskilled labor in the u s will lose under a program of free trade using a general equilibrium model of production factor shares industry shares and estimates of substitution for skilled labor unskilled labor and capital are used to examine comparative statics the interplay of factor intensity and factor substitution in the three factor production structure has proven a considerable analytical challenge building on the textbook production model with two factors the third productive factor allows technical complementarity and creates a more complex pattern of factor intensity both factor intensity and factor substitution affect the qualitative nature of the comparative statics little is known about the model s quantitative properties a 3 x 3 model with outputs of the three major sectors agriculture manufacturing services is specified and a 3 x 2 model without agriculture is also examined factor substitution is estimated with production function across states skilled labor separated by various census categories cannot be aggregated with unskilled labor in any sector and constant returns to scale cannot be rejected as a null hypothesis additionally the three inputs capital labor skilled labor are all technical substitutes comparative static results follow a pattern suggested by factor intensity changing prices of goods generally have elastic effects on factor prices stolper samuelson results in other words have a quantitative weight price changes due to a program of free trade will significantly affect income distribution similarly rybczynski type results are quantitatively significant in that factor endowment changes have elastic effects on outputs the implication is that output patterns will differ significantly across freely trading partners elasticities of factor prices with respect to endowment changes on the other hand are very inelastic this inelasticity suggests that there would only be small long run effects of international migration capital flows or endowment differences on the international pattern of factor income this inelasticity is called near factor price equalization nfpe under nfpe freely trading countries will experience a vector of factor prices nearly equal to each other nfpe suggests that the qualitative effects of changing or different factor endowments

how do environmental regulation and environmental decentralization affect green total factor energy efficiency evidence from china abstract green development is critical for china s economic transformation enhancing green total factor energy efficiency hereafter gtfee is vital to emission reduction and to win win industrial development this study uses the panel data of 30 chinese provinces for the period 2005 2016 to investigate the relationship between environmental regulation and china s gtfee the spatial durbin model is employed to control for the possible spatial spillover effect a dynamic threshold panel model that can effectively address the endogeneity problem and regional heterogeneity is utilized to examine the potential non linear relationship between environmental regulation and gtfee under different conditions of environmental decentralization the estimation results indicate that there is a significant u shaped relationship between environmental regulation and china s gtfee with the further expansion of environmental decentralization the local government s autonomous choice of pollution control is improved the improvement of environmental decentralization can lead to negative moderating effect of environmental regulation on gtfee additionally the regression results of dynamic threshold model show that environmental decentralization can increase the negative influences of environmental regulation on gtfee interestingly the non linear impact of environmental regulation on gtfee is dependent on the specific type of environmental decentralization higher degree of environmental decentralization can lead to an increase in the restraining effect of environmental regulation on gtfee however an improvement in the decentralization of environmental supervision and environmental monitoring can increase the negative influences of environmental regulation on gtfee

ecological modernisation new perspectives abstract ecological modernisation understood as systematic eco innovation and its diffusion has by far the largest potential to achieve environmental improvements in general the market logic of modernisation and competition for innovation combined with the market potential of global environmental needs serve as important driving forces behind ecological modernisation in recent times however additional factors like rising energy prices or fears from climate change have favoured the rise of this innovation based approach to environmental policy the article deals with two special driving forces first there is growing evidence for the importance of smart environmental regulation secondly the increasingly complex actor constellation of global environmental governance leads to mounting business risks for polluters and thereby exerts pressure for eco innovation despite these favourable framework conditions the strategy of ecological modernisation nonetheless faces a number of inherent limitations these include the unavailability of marketable technological solutions for relevant environmental problems like the loss of species the rebound effect neutralising the incremental environmental improvements through economic growth the dilemma of the n curve as well as resistance by modernisation losers against this background structural solutions seem indispensable here eco innovations should be supported by transition management or ecological structural policy

solving the return deviation conundrum of leveraged exchange traded funds the large deviation of the actual return of a leveraged exchange traded fund letf from the leveraged multiple of the underlying index return has drawn considerable attention from investors regulators and the financial media despite this attention the sources and fundamental determinants of the letf return deviation remain unidentified this study constructs a clear unified objective and executable framework that addresses the behaviors sources and determinants of the letf compounding and noncompounding deviations our theoretical predictions and empirical results hold the promise of guiding investors regulators financial advisors and portfolio managers toward a thorough understanding of the return behavior of letfs

international trade with a public intermediate good abstract the purpose of this paper is to investigate familiar trade theorems such as the stolper samuelson samuelson rybczynski heckscher ohlin and factor price equalization theorems when a public intermediate good is accommodated in the 2 2 general equilibrium trade model the public good which is introduced by the lindahl pricing rule is assumed to be of a semipublic kind then we present the circumstances where the positive results for all of the above theorems except the factor price equalization theorem hold as for factor price equalization we show that there is a tendency for trade to equalize prices

the options of local authorities for addressing climate change and energy efficiency through environmental regulation of companies abstract environmental regulation of companies is sometimes in the literature characterised as a successive broadening of focus and policy instruments from applying command and control mechanism to get companies to clean and or dilute local pollutants through end of pipe solutions towards applying various means to influence and facilitate companies to act proactively in preventing pollution through cleaner production waste prevention and resource efficiency this understanding is contested in this article the article documents instead a gap in respect to the local authorities actual execution of the direct regulation of companies in denmark the practice of the local competent authorities is found to primarily still target local environmental concerns by command and control means the objective of the article is to analyse this discrepancy between the overall representation of regulatory trends and the actual practices of local authorities in denmark the overall constraints that local authorities encounter are investigated in respect to 1 addressing energy efficiency and reduction of ghg emissions through juridical requirements in permits and injunctions and 2 facilitating and promoting reductions of energy consumption and ghg emissions during inspections the assessment is based on the triangulation of different data a qualitative interviews with environmental officers from seven local authorities taking part in a eu life project carbon 20 b a documentary review of political documents and evaluations of the danish regulations as well as c an interview and subsequent correspondence with an employee at the danish environmental protection agency

history dependent paths and trade gains in a small open economy with a public intermediate good this study reexamines mcmillan s international economic review 19 1978 665 78 analysis of a dynamic small open economy with a public intermediate good concerning the trade patterns of the open economy we find results that were overlooked in mcmillan s analysis among others if labor endowment is of intermediate size there are two saddle point steady states and the initial stock of the public good determines the long run trade pattern we also add a gains from trade analysis to mcmillan s model and demonstrate that if the economy has a comparative advantage in a good with productivity less sensitive to the public intermediate good the economy may lose from trade at the steady state

a theorem on income distribution in a small open economy abstract if the number of productive factors exceeds the number of commodities produced changes in factor endowments and or any commodity price will alter factor prices in a way that depends both upon factor intensities and the degree of factor substitutability however bilateral factor intensity rankings for constant price industries by themselves restrict possible factor price changes if factors are ranked from most to least intensive in any such pair of industries all the gainers cannot be located at one end of the ranking

international factor movements and the ramaswami argument in a succinct but classic article appearing in economica in 1968 ramaswami put forth an argument supporting the superiority of a policy that attracts foreign factors over a policy that allows a relatively abundant factor to emigrate in each case the active home country is assumed to levy taxes on factor flows so as to capture for itself the discrepancy in return to the same factor at home and abroad the asymmetry reflected by this policy ranking rests on a basic propeity of production functions the convexity of technology plus the ability of the active home country to hire or rent out factors at wages or rentals prevailing in the foreign country briefly put the ramaswami argument proceeds as follows suppose the active home country is capital abundant and has levied on optimal tax on earnings of its own capital operating abroad now consider repatriating this capital and allowing for the first time some inflow of foreign labour in particular suppose the home country allows a level of immigration identical to the labour force previously employed with the home capital that is being repatriated such a transfer of home capital and foreign labour out of the foreign country leaves factor proportions abroad undisturbed and thus does not alter the wage that must be paid to attract the requisite bundle of foreign workers although the home country thus avoids any increase in factor costs in foreign markets it can increase output since the capital labour ratiooriginally employed at home at high home wage rates is greater than the ratio in the freshly acquired bundle from abroad by adopting a uniform capital labour ratio over all factors now employed at home output and thus real income rises there may be even further gains to be had by allowing yet a different optimal level of immigration in the home country which has now banned capital exports 2 essential to the ramaswami argument is the ability of the home country to extract a bundle of factors previously employed abroad without disturbing factor prices in that country indeed jones coelho and easton 1983 have suggested that in the context of the ramaswami discussion the original argument could be pursued to suggest that the home country gains not only from repatriating its own capital but from actually encouraging foreign capital to be employed at home such a capital flow is admittedly uphill the home country would have to pay out more in rentals than such capital can earn at home despite this fact such an import of capital and labour in the same proportions found abroad does not alter foreign factor prices but does via the same ramaswami type argument on the convexity of the technology result in gains at home although ramaswami s own discussion starts with a repatriation of home capital previously invested abroad his argument can be applied directly to the foreign autarky factor endowment bundle if technology exhibits constant returns to scale and if all both factors are indeed internationally

the upstairs market for large block transactions analysis and measurement of price effects this article develops a model of the upstairs market where order size beliefs and prices are determined endogenously we test the model s predictions using unique data for 5 625 equity trades during the period 1985 to 1992 that are known to be upstairs transactions and are identified as either buyer or seller initiated we find that price movements prior to the trade date are significantly positively related to trade size consistent with information leakage as the block is shopped upstairs further the temporary price impact or liquidity effect is a concave function of order size which may result from upstairs intermediation

unemployment and trade liberalisation in contrast to the focus of the public debate over trade liberalisation on job losses there is a widespread view among economists that unemployment and trade issues should be considered separately this view cannot be justified theoretically and ignores the growing number of general equilibrium trade models with unemployment in a simple model with an exogenous wage floor trade liberalisation can lead to either gains or losses depending on the production technology severity of the factor market distortion factor intensities of the industries and conditions in trading partners definite results can be derived about gains from liberalising trade with lower wage floors about relative abundance of the unemployed factor dampening losses when trade is liberalised and about gains when the good which uses the unemployed factor is exported the theoretical models are then linked to the policy modelling literature using the example of recent australian controversies over liberalisation of trade in automobiles and textiles it is argued that trade liberalisation would be better advanced by including endogenous employment in trade policy simulation exercises and by discussing employment effects rather than brushing them aside as temporary adjustment problems or regional difficulties

free trade and factor price polarization abstract factor price equalization between trading partners is perhaps the best known implication of the heckscher ohlin samuelson model of production and trade it has long been known that with more primary factors than goods this result is not necessary recent studies have investigated effects of changing prices on factor payments in the three factor two good trade model this short note emphasizes that when such an economy moves from autarky to free trade payment to a relatively cheap factor may fall polarizing factor prices conditions favoring this outcome are examined

the backward incidence of pollution control in a rigid wage economy abstract the backward incidence of pollution controls onto the polluting and nonpolluting industries is examined in a two sector rigid wage economy characterized by unemployment in both the short run and the long run as expected more restrictive pollution controls result in contraction in the polluting sector and expansion in the nonpolluting sector somewhat unexpectedly national income may rise with stronger pollution controls if the polluting industry is relatively capital intensive

factor movements with three factors and two goods in the u s economy abstract ruffin s 1981 theoretical finding that extreme factors must be enemies and the middle factor must be a friend of both extreme factors with constant product prices in a three factor two good general equilibrium model is confirmed empirically for the united states results are used to explain the positions factor owners take on issues of factor movement policies

the dynamics of short term mutual fund flows and returns a time series and cross sectional investigation abstract this study analyzes the dynamics of daily mutual fund flows a vector auto regression var of flows and returns shows that the behavior of fund investors is more consistent with contrarian rather than momentum characteristics past fund flows have a positive impact on future fund returns with the long term information effect dominating the transient price pressure effect seasonality in daily flows such as day of week and day of month patterns are present and daily flows are generally mean reverting probit regressions indicate that fund investment objective marketing policy and level of active management explain cross sectional variation in the behavioral patterns displayed in daily flows our results are robust to the different methods of calculating daily flows based on whether or not the day end tna figures include the current day s flow throughout the analysis we contrast the dynamics of daily flows with established results for monthly fund flows and find important differences between the two

industrial shut downs and medium run factor intensity reversals while short run factor intensity reversals lead to industrial shut downs when there are two productive factors this paper shows that an industry can undo an intensity reversal over the medium run and avoid shutting down when there are three or more factors medium run adjustment begins with a capital fixed input and extends until it has become perfectly mobile j peter neary 1978 develops a picture of adjustment with two industries and two inputs where an industry must shut down following an intensity reversal the present study adds a third input skilled labor or natural resources to capital and labor

do tariffs protect specific factors it is shown that a tariff can lower payment to a productive factor used only in specific to the protected industry in a simple production model this may occur anytime the protected sector shares more than one common factor with the rest of the economy as seems most likely intuition based on the well known specific factors model where sectors share a single common factor should be modified whether specific factors effectively receive protection from tariffs becomes an empirical issue

technology and public goods abstract this paper presents a theory of public goods based on production theory where public goods are viewed as inputs to the production process we examine the pure case of public inputs no private inputs as well as the mixed case private and public inputs we show how the case of public inputs is related to certain forms of nonjoint production and we characterize it in terms of variable profit and joint cost functions comparative statics results are derived graphically in the two by two case

the business ethics of short selling and naked short selling the controversy over short selling has continued unabated from the introduction of modern equity trading in amsterdam in 1610 to the present day nevertheless the business ethics literature has not really addressed short selling short sellers not only profit from the misery of others they also create it through their selling activities however they also provide a socially useful service by making prices better reflect true values protecting other investors from purchasing overpriced securities short sellers can also help to provide liquidity in the markets recently there has been a hue and cry against so called naked short selling which involves not delivering the shares that have been sold this gives manipulators a tool for depressing stock prices and deprives purchasers of voting rights and potential stock lending revenue naked short selling creates ethical issues for short sellers buyers brokers market makers and regulators is it ethical to exploit a legal loophole that permits sellers to sell stock and delay delivering shares indefinitely

complementarity in a simple general equilibrium production model a simple three factor two good general equilibrium model allowing complementarity in production is examined conclusions of general equilibrium economics with two factors must be reinterpreted and qualified when complementarity is possible sign patterns of how changing factor endowments affect outputs and how changing prices affect factor payments are uncovered for a small open economy results should prove valuable to a wide range of economists interested in extending general equilibrium analysis to include complementary factors of production
