dodging the grabbing hand the determinants of unofficial activity in 69 countries across 69 countries higher tax rates are associated with less unofficial activity as a percent of gdp but corruption is associated with more unofficial activity entrepreneurs go underground not to avoid official taxes but to reduce the burden of bureaucracy and corruption dodging the grabbing hand in this way reduces tax revenues as a percent of both official and total gdp as a result corrupt governments become small governments and only relatively uncorrupt governments can sustain high tax rates 2000 elsevier science s a all rights reserved

regulatory discretion and the unofficial economy johnson kaufmann and shleifer 1997 find that the share of the unofficial economy in gdp is determined by the extent of control rights held by politicians and bureaucrats in post communist economies exploring in more detail the role of bribes and using a broader data set from the oecd latin america and transition economies we find that the unofficial economy accounts for a larger share of gdp when there is more corruption and when the rule of law is weaker while these findings are consistent with the earlier results for transition economies in the larger country sample we find it is not necessarily the case that more regulation or higher taxes directly increases the size of the unofficial economy the problem appears to be not regulation or taxation per se but whether the state administrative system can operate without corruption a high level of regulatory discretion helps create the potential for corruption and drive firms into the unofficial economy

the impact of wind power generation on the electricity price in germany abstract this paper investigates the relationship between intermittent wind power generation and electricity price behaviour in germany using a garch model i evaluate the effect of wind electricity generation on the level and the volatility of the electricity price in an integrated approach the results show that variable wind power reduces the price level but increases its volatility this paper s results also indicate that regulatory change has stabilised the wholesale price the electricity price volatility has decreased in germany after a modification of the marketing mechanism of renewable electricity this gives confidence that further adjustments to regulation and policy may foster a better integration of renewables into the power system

dynamic pricing of electricity as both a regulator and an academic fred kahn argued that end use electricity consumers should face prices that reflect the time varying marginal costs of generating electricity this has been very slow to happen in the us even in light of recent technological advances that have lowered costs and improved functionality for meters and automated demand response technologies we describe these recent developments and discuss the remaining barriers to the proliferation of time varying electricity pricing

counterfactual decomposition of changes in wage distributions using quantile regression we propose a method to decompose the changes in the wage distribution over a period of time in several factors contributing to those changes the method is based on the estimation of marginal wage distributions consistent with a conditional distribution estimated by quantile regression as well as with any hypothesized distribution for the covariates comparing the marginal distributions implied by different distributions for the covariates one is then able to perform counterfactual exercises the proposed methodology enables the identification of the sources of the increased wage inequality observed in most countries specifically it decomposes the changes in the wage distribution over a period of time into several factors contributing to those changes namely by discriminating between changes in the characteristics of the working population and changes in the returns to these characteristics we apply this methodology to portuguese data for the period 1986 1995 and find that the observed increase in educational levels contributed decisively towards greater wage inequality copyright 2005 john wiley sons ltd

investment under uncertainty with price ceilings in oligopolies abstract we study the impact of price cap regulation on the level and timing of investment in an oligopolistic cournot industry facing stochastic demand we find that a price ceiling affects investment decisions in two mutually competing ways it makes the option to defer investment more valuable but at the same time it reduces the incentive for firms to strategically underinvest in order to raise prices we show that while sensible price cap regulation speeds up investment a low price cap can be a disincentive for investment there exists an optimal price cap independent of market concentration the competitive investment price trigger that maximizes investment incentives and in the long term increases industry installed capacity this optimal price cap becomes less effective and less robust as the market becomes more competitive and as demand volatility increases errors in estimation of the optimal price cap have asymmetric effects underestimation has more dire consequences than overestimation

investment and capacity choice under uncertain demand this paper extends the real options literature by discussing an investment problem where a firm has to determine optimal investment timing and optimal capacity choice at the same time under conditions of irreversible investment expenditures and uncertainty in future demand after the project is installed with a certain maximum capacity this capacity is fixed as an upper boundary to the output and cannot be adjusted later on it turns out that in the framework of this once and for all decision uncertainty in future demand leads to an increase in optimal installed capacity but on the other hand it causes investment to be delayed to an extent that even small uncertainty makes waiting and accumulation of further information the optimal decision for large ranges of demand limiting the capacity which may be installed weakens this extreme effect of uncertainty

policy implications of the purchasing intentions towards energy efficient appliances among china s urban residents do subsidies work incentive policies are always used to sway purchase retail stocking and production decisions toward energy efficient products by many countries or regions so the effectiveness of such subsidies has been of much concern to scholars this research focused on whether or not subsidy policies have guided people s intentions and behaviours we investigated 436 urban residents from 22 provinces in china covering the seven major geographic regions and made an empirical analysis of the factors influencing chinese urban residents purchasing intentions towards energy efficient appliances based on the structural equation model on theoretical aspect we developed the theory of planned behaviour our results show that the variable policy is insignificant which indicates that policy environment and media propaganda in china do not have significant effect on chinese residents willingness to pay for energy efficient appliances while the residents environmental awareness past purchasing experiences social relationships age and level of education all exert a significant influence on chinese residents purchasing intentions finally based on the above research results the corresponding policy suggestions which mainly focus on the time of subsidy the object of subsidy and the method of subsidy are offered for policy makers

cointegration analysis of spot electricity prices insights on transmission efficiency in the western us abstract the us energy policy act of 1992 promoted the development of spot markets for electric power by requiring utilities to open their transmission systems to wholesale power sales in this paper we specify and estimate a vector error correction model using peak and off peak electricity spot prices during 1994 1996 covering 11 regional markets in the western united states and test these prices for evidence of market integration the results show evidence of an efficient and stable wholesale power market

estimating direct and indirect rebound effects for u s households with input output analysis part 2 simulation abstract this is the second part of a two part paper that integrates economic and industrial ecology methods to estimate the indirect rebound effect from residential energy efficiency investments we apply the model developed in part one to simulate the indirect rebound given an estimate of the direct rebound using a 2002 environmentally extended input output model and the 2004 consumer expenditure survey in 2002 for the u s we find an indirect rebound of 5 15 in primary energy and co 2 e emissions assuming a 10 direct rebound depending on the fuel saved with efficiency and household income the indirect rebound can be as high as 30 40 in no x or so 2 emissions for efficiency in natural gas services the substitution effect modeled in part one is small in most cases and we discuss appropriate applications for proportional or income elasticity spending assumptions large indirect rebound effects occur as the u s electric grid becomes less carbon intensive in households with large transportation demands or as energy prices increase even in extreme cases there is limited evidence for backfire or a rebound effect greater than 100 enacting pollution taxes or auctioned permits that internalize the externalities of energy use would ensure that rebound effects unambiguously increase consumers welfare

estimating direct and indirect rebound effects for u s households with input output analysis part 1 theoretical framework abstract this is the first part of a two part paper providing an analytical model of the indirect rebound effect given a direct rebound estimate that integrates consumer demand theory with the embodied energy of household spending from environmentally extended input output analysis the second part applies the model developed in part one to simulate the direct and indirect rebound for the average u s household in terms of primary energy co2e nox and so2 emissions and for energy efficiency investments in electricity natural gas or gasoline services part one provides a critical review of the largely independent economic and industrial ecology literatures on the indirect rebound by studying the two goods case and the n goods case we demonstrate that the indirect rebound is bounded by the consumer budget constraint and inversely related to the direct rebound we also compare the common proportional spending and income elasticity spending assumptions with our model of cross price elasticities including both substitution and income effects for the indirect rebound by assuming zero incremental capital costs and the same embodied energy as conventional technologies for efficient appliances we model an upper bound of the indirect rebound future work should also consider the increase in consumer welfare possible through the rebound effect

does urbanization lead to more direct and indirect household carbon dioxide emissions evidence from china during 1996 2012 china is experiencing a stage of rapid urban development the energy consumption and related carbon dioxide emissions of households continue to increase this paper calculates direct and indirect carbon dioxide emissions of households based on the input output method in china from 1996 to 2012 the results reveal that there were more total carbon dioxide emissions from urban households than from rural households far more indirect emissions from urban households than from rural households slightly more direct emissions from urban households than from rural households and differences in direct carbon dioxide emissions from various fuels and in indirect emissions from various sectors between urban and rural households to examine the causal relationship between urbanization and the carbon dioxide emissions of households cointegration and granger causality tests are applied a unidirectional causal relation was found running from urbanization to both direct and indirect household carbon dioxide emissions and the direct and indirect carbon dioxide emissions of households would increase 2 9 and 1 1 respectively for every increase of one percent in urbanization we discuss the reasons of why the development of urbanization will lead to more household direct and indirect carbon dioxide emissions and suggest certain policy implications for urbanization and carbon dioxide emissions based on the results of this study

releasing constraints to growth or pushing on a string policies and performance of mexican micro firms abstract using firm level data from mexico this paper investigates the firm characteristics associated with participation in credit markets access to training tax payments and membership in business associations we find that firms which participate in these institutions exhibit significantly higher profits moreover firms that borrow from formal or informal sources and those that pay taxes are significantly more likely to stay in business but firms that received credit exhibit lower rates of income growth these results persist when firm characteristics that are arguably correlated with unobserved entrepreneurial ability are controlled for our findings suggest that the significant within country differences in firm productivity observed in developing economies are due in part to market and government failures that limit the ability of micro firms to reach their optimal sizes

the impacts of china s household consumption expenditure patterns on energy demand and carbon emissions towards 2050 abstract this paper explores how china s household consumption patterns over the period 2005 2050 influence the total energy demand and carbon dioxide co2 emissions in two baseline scenarios and how it influences carbon prices as well as the economic cost in the corresponding carbon mitigation scenarios to this end we first put forward two possible household consumption expenditure patterns up to 2050 using the working leser model taking into account total expenditure increase and urbanization for comparison both expenditure patterns are then incorporated in a hybrid recursive dynamic computable general equilibrium model the results reveal that as income level increases in the coming decades the direct and indirect household energy requirements and co2 emissions would rise drastically when household expenditure shifts from material products and transport to service oriented goods around 21 000 mtce 1 of primary energy and 45 billion tons of co2 emissions would be saved over the 45 year period from 2005 to 2050 moreover carbon prices in the dematerialized mitigation scenario would fall by 13 in 2050 thus reducing the economic cost

revisiting long run relations in power markets with high res penetration abstract electricity generation from renewable energy resources res has become increasingly significant to reach eu and emissions reduction targets at the same time one of the main eu policy goals has been the creation of a common internal energy market for europe in this paper we focus on these two issues previously studied separately considering their possible interactions we first analyze the long run relationship between day ahead electricity prices and fuel prices natural gas and coal looking at two samples of years characterized by low and high res penetration then we explore the integration of eu markets we show that the electricity fuel nexus found over 2006 2008 changed dramatically over 2010 2014 for the majority of countries considered in particular the long run dependence of electricity from gas and coal prices is much lower in recent years furthermore our results confirm that the considered eu countries are becoming less integrated as res e increases our findings suggest that nationally implemented policies to support renewables are successful in increasing res penetration but they have lessened the linkage among eu markets then making integration more difficult to obtain

energy consumption practices of rural households in north china basic characteristics and potential for low carbon development reducing the climate impact of rural household energy consumption in china is complicated since it is bound up with deeply routinized daily practices and dependent from existing infrastructural systems of energy supply to assess the potential for low carbon development we first estimate the overall co2 emissions of rural households followed by a more in depth description and characterization of the different energy use practices within the households space heating turns out to be the largest emission source among domestic energy practices in north china we present lifestyle and context related factors that help to explain existing differences in domestic energy use practices of households the potential for low carbon development is discussed both at the demand side and the supply side at the demand side the use of more efficient technologies and cleaner energy sources for space heating seems to be a high potential measure for achieving low carbon households at the supply side the reduction of rural domestic co2 emissions could be effectively supported by making available to householders renewable and cleaner energy sources and technologies in order to be effective such low carbon energy options should take into account the income characteristics and lifestyles of rural householders

formal measures of the informal sector wage gap in mexico el salvador and peru using comparable micro level data from three countries we ask what type of person works in the informal sector and whether informal workers earn lower wages than observationally equivalent workers in the formal sector the characteristics of informal workers are similar across countries surprisingly when we control for these personal characteristics we find a significant wage premium associated with formal employment in el salvador and peru but a premium associated with work in the informal sector in mexico a model of endogenous selection offers little help in explaining the differences in wage patterns the research casts doubt on the received wisdom that the informal sector always and everywhere is a poorly paid but easily entered refuge for those who have no other employment opportunities this abstract was borrowed from another version of this item

heterogeneity in german residential electricity consumption a quantile regression approach abstract in the absence of sufficient coverage of metering data on the electricity consumption of individual devices this paper estimates the contribution of individual appliances to overall household electricity consumption drawing on the most recent wave of the german residential energy consumption survey grecs moving beyond the standard focus of estimating mean effects we combine the conditional demand approach with quantile regression methods to capture the heterogeneity in electricity consumption rates of individual appliances our results indicate substantial differences in these rates as well as the end use shares across households originating from the opposite tails of the electricity consumption distribution this outcome highlights the added value of applying quantile regression methods in estimating consumption rates of electric appliances and indicates some scope for realizing conservation potentials

long run relations in european electricity prices this paper analyses the interdependencies existing in wholesale electricity prices in six major european countries the results of a robust multivariate long run dynamic analysis reveal the presence of four highly integrated central european markets france germany the netherlands and austria the trend shared by these four electricity markets appears to be common also to gas prices but not to oil prices the existence of a common long term dynamics among electricity prices and between electricity prices and gas prices can be explained by the similarity of the market design across europe and by the same marginal generation technology since standard unit root and cointegration tests are not robust to the peculiar characteristics of electricity prices time series we also develop a battery of robust inference procedures that should assure the reliability of our results copyright 2009 john wiley sons ltd

low carbon behavior approaches for reducing direct carbon emissions household energy use in a coastal city abstract household carbon emissions from energy use are rapidly increasing in conjunction with growing urbanization their reduction is critical for local urban climate improvement and the sustainable development of cities low carbon behavior is proved as a key element determining residents lifestyle understanding how that behavior affects household energy use will be useful in promoting low carbon households in this study xiamen a coastal city was divided into areas at high and low risk of flooding we used the path analysis method integrated with behavior and socioeconomic factors to explore the mechanisms of low carbon behavior effects on household direct energy use and related carbon emissions we found that socioeconomic conditions combined with low carbon behavior had direct and indirect impacts on household carbon emissions low carbon behavior in the high risk area contributed most to reducing carbon emissions education level was the important factors in the low risk area government led policies encouraging low carbon behavior were effective in reducing household carbon emissions in the high risk area however in low risk areas education about a low carbon lifestyle is an effective means for reducing carbon emissions

shadow economies size causes and consequences using various methods the size of the shadow economy in 76 developing transition and oecd countries is estimated average size varies from 12 percent of gdp for oecd countries to 23 percent for transition countries and 39 percent for developing countries increasing taxation and social security contributions combined with rising state regulations are driving forces for the increase of the shadow economy especially in oecd countries according to some findings corruption has a positive impact on the size of the shadow economy and a growing shadow economy has a negative effect on official gdp growth

the rebound effect microeconomic definitions limitations and extensions abstract the rebound effect results in part from an increased consumption of energy services following an improvement in the technical efficiency of delivering those services this increased consumption offsets the energy savings that may otherwise be achieved if the rebound effect is sufficiently large it may undermine the rationale for policy measures to encourage energy efficiency the nature and magnitude of the rebound effect is the focus of long running dispute with energy economics this paper brings together previous theoretical work to provide a rigorous definition of the rebound effect to clarify key conceptual issues and to highlight the potential consequences of various assumptions for empirical estimates of the effect the focus is on the direct rebound effect for a single energy service indirect and economy wide rebound effects are not discussed beginning with khazzoom s original definition of the rebound effect we expose the limitations of three simplifying assumptions on which this definition is based first we argue that capital costs form an important part of the total cost of providing energy services and that empirical studies that estimate rebound effects from variations in energy prices are prone to bias second we argue that energy efficiency should be treated as an endogenous variable and that empirical estimates of the rebound effect may need to apply a simultaneous equation model to capture the joint determination of key variables third we explore the implications of the opportunity costs of time in the production of energy services and highlight the consequences for energy use of improved time efficiency the influence of time costs on the rebound effect and the existence of a parallel rebound effect with respect to time each of these considerations serves to highlight the difficulties in obtaining reliable estimates of the rebound effect and the different factors that need to be controlled for we discuss the implications of these findings for econometric studies and argue that several existing studies may overestimate the magnitude of the effect

a market approach to long term security of supply the problem of ensuring that there is enough generation capacity to meet future demand has been an issue in market design since the beginning of the deregulation process although ideally the market itself should be enough to provide adequate investment incentives there are several factors that prevent this result from being achieved and some actual markets have already experienced problems related with a lack of generation capacity a regulatory framework to address this question is presented the procedure is based on an organized market where reliability contracts based on financial call options are auctioned so both their price and their allocation among the different plants are determined through competitive mechanisms this results in a stabilization of the income of the generators and provides a clear incentive for new generation investment with a minimum of regulatory intervention additionally the method represents a market compatible mechanism to hedge demand from the occurrence of high market prices

modelling the informal sector formally abstract the theoretical characterization of formal informal sector dualism by labor market dualism is integrated with its empirical characterization by size dualism by supposing that the minimum formal sector wage is only enforced for firms greater than a certain size a firm s size varies directly with the talent of its enterpreneur manager and the choice between formal and informal sector entrepreneurship is determined endogenously it is then shown that the size gap between the smallest formal sector firm and largest informal sector firm varies directly with the formal informal sector wage differential which in turn is shown as expected to increase the further is the minimum wage above the market clearing wage the comparative statics of changes in the size of the firm above which the minimum wage is enforced are also examined

the intensity and timing of investment the case of land the authors model the decision to replace durable capital when intensity is variable decisions of this type include land redevelopment decisions where the density of residential or commercial development is a choice variable as well as capital replacement decisions where capacity is variable the authors provide a general yet simple formation of the problem using an optimal stopping framework they characterize the value of the project the timing of investment and the intensity of development the authors show that intensity interacts in important ways with timing taxes and project values the ability to vary intensity raises hurdle rents and delays development decisions copyright 1994 by american economic association

the role of income in energy consumption behaviour evidence from french households data the main purpose of this paper is to characterise quantitatively the impact of income on household energy consumption in the residential and transport sectors starting from the data collected in a paper survey we analyse the extent of the constraint experienced by households in terms of equipment purchasing behaviour and daily energy consumption this analysis shows that the least well off households are particularly constrained since the share of their budget represented by these energy services is very large 15 25 and this corresponds to a level of energy service well below that of the better off households the case of space heating shows a factor of 2 in terms of level of comfort achieved between the extreme 10 percentiles these households also face a strong capital constraint for equipment purchases this leads either to a large increase in the required rate of return or to a reduction in the proportion of households that are prepared to replace their equipment earlier the least well off households are thus doubly constrained since it is more difficult for them to invest in our opinion it is crucial to take into account this observation in the context of political measures aimed at reducing households co2 emissions

comparison of energy efficiency subsidies under market power abstract energy efficiency subsidies are very popular all over the world for energy conservation and emission reduction by using a game theory model this article captures the differences of two important types of subsidies fixed subsides and output subsidies some interesting conclusions are achieved and some social phenomena are rationally explained firstly increasing total subsidies increases the number of subsidized firms moreover fiercer competition produces more firms to be subsidized thus the number of subsidized firms depends on the competition in this industry secondly output subsidies achieve a higher consumer surplus and a lower producer surplus than do fixed subsidies therefore consumers like output subsidies while firms like fixed subsidies finally output subsidies achieve a more favorable environmental impact and subsidize more firms than do fixed subsidies that is the environmental effects of output subsidies dominate those of fixed subsidies in summary based on both the effects on the environment and the consumer surplus this article supports output subsidies and explains the advantages of output subsidies

informal sector the credit market channel abstract we build a model of firms choice between formality and informality complying with costly registration procedures allows the firms to benefit from key public goods enforcement of property rights and contracts that make the participation in the formal credit market possible in a moral hazard framework with credit rationing their decision is shaped by the interaction between the cost of entry into formality and the relative efficiency of formal versus informal credit mechanisms and their related institutional arrangements the model is consistent with existing stylized facts on the determinants of informality

mobility in the urban labor market a panel data analysis for mexico abstract we analyze mobility in urban mexico between three labor market states working in the formal sector working in the informal sector and not working a dynamic multinomial logit panel data model with random effects is used explaining the labor market state of each individual during each time period the data are drawn from mexico s urban employment survey a quarterly household survey for urban mexico while some of the descriptive statistics suggest that informal sector jobs are inferior to formal sector jobs formal tests cannot reject the null hypothesis of equal transition rates between formal and informal sector jobs for homogeneous groups of workers looking at entry and exit into and out of nonemployment we find that transitions from formal sector jobs to nonemployment were less likely than transitions from informal sector jobs to nonemployment in 1992 but not in 1999 suggesting that employment protection in the formal sector has been reduced

residential energy consumption in urban china a decomposition analysis abstract residential energy consumption rec is the second largest energy use category 10 in china and urban residents account for 63 of the rec understanding the underlying drivers of variations of urban rec thus helps to identify challenges and opportunities and provide advices for future policy measures this paper applies the lmdi method to a decomposition of china s urban rec during the period of 1998 2007 at disaggregated product activity level using data collected from a wide range of sources our results have shown an extensive structure change towards a more energy intensive household consumption structure as well as an intensive structure change towards high quality and cleaner energy such as electricity oil and natural gas which reflects a changing lifestyle and consumption mode in pursuit of a higher level of comfort convenience and environmental protection we have also found that china s price reforms in the energy sector have contributed to a reduction of rec while scale factors including increased urban population and income levels have played a key role in the rapid growth of rec we suggest that further deregulation in energy prices and regulatory as well as voluntary energy efficiency and conservation policies in the residential sector should be promoted

informal employment safety net or growth engine summary is informal employment a safety net or a growth engine to address this question this paper studies the trends and cycles of informal employment it first presents a theoretical model of long and short run behavior of informal labor then it analyzes these relationships empirically using the share of self employment in the labor force as the proxy for informal employment in the long run informality is larger when labor productivity is lower government services weaker and business flexibility less prevalent in the short run informal employment behaves counter cyclically indicating that it acts primarily as a safety net the degree of counter cyclicality however varies inversely with the size of informal labor itself

modeling informality formally households and firms i introduction recent estimates indicate that around 10 of gross domestic product gdp in the united states is produced by individuals or firms that evade taxes schneider and enste 2000 in latin america approximately 50 of all salaried employees work informally an important question is therefore what are the determinants of informality unfortunately three decades of research have not yet yielded a consensus opinion on this point the traditional explanation initiated with the work of lewis 1954 assumes the existence of segmented labor markets in which some workers do not have access to jobs in the regulated formal sector these workers are forced to accept lower paying informal sector jobs that usually involve inferior working conditions while this view has become prevalent in the development literature direct empirical tests of the premise that informal workers would expect higher wages in the formal sector yield mixed results for instance magnac 1991 maloney 2004 and pratap and quintin 2004 do not find compelling evidence of segmentation between the formal and the informal sectors using data from colombia mexico and argentina respectively it is nonetheless certainly plausible that the presence of unions might segment the labor market layard et al 1991 however even if we believe that unionization has been an important factor in determining labor market segmentation in the past the pronounced decline of unionization throughout latin america over the last two decades seems to be a less satisfactory explanation of the phenomenon at the present time especially since informality increased in most countries in latin america during the same period gasparini and tornarolli 2006 another approach emphasizes the role of labor market regulation and taxation as the main cause of informality a pioneering study by de soto 1989 describes how informal workers develop their own laws and institutions to make up for the shortcomings of the official legal system it is certainly true that the size of the shadow economy is affected by the burden of taxes and social security contributions as well as by the many other regulations governing the official economy the problem with adopting this explanation of informality unreservedly however is that it overlooks the fact that workers have nonpecuniary preferences for the sector they work for and these preferences play a role in determining the equilibrium level of formality of an economy in particular workers in the informal sector are not eligible for socially mandated benefits three stylized facts characterize informality 1 small firms tend to operate informally while large firms tend to operate formally 2 unskilled workers tend to be informal while skilled ones have formal jobs 3 ceteris paribus secondary workers a worker other than the household head are less likely to operate formally than primary workers in this paper we present a model of an economy in which the sizes and wages of the formal and informal sectors are endogenously determined that accounts for these three facts our model entails a continuum of types on both sides of the labor market i e firms and workers firms choose whether to operate formally or informally and workers choose in what sector they work in equilibrium managerial talent determines size dualism at the firm level and human capital is the factor that determines whether workers are employed in the formal or informal sector in our model both heterogeneous firms and workers have preferences over the sectors they operate and choose optimally whether to function formally or informally by contrast a prominent feature of the preexisting literature is the idea that workers decisions play no role in determining the equilibrium of the economy thus our model is the first one in which policies that affect workers preferences as well of course as firm preferences over the formal or the informal sector such as pension plans public health issues and unemployment and any social benefits will affect the sizes and wages of the formal and the informal sectors

determinants of household energy consumption in india improving access to affordable modern energy is critical to improving living standards in the developing world rural households in india in particular are almost entirely reliant on traditional biomass for their basic cooking energy needs this has adverse effects on their health and productivity and also causes environmental degradation this study presents a new generic modelling approach with a focus on cooking fuel choices and explores response strategies for energy poverty eradication in india the modelling approach analyzes the determinants of fuel consumption choices for heterogeneous household groups incorporating the effect of income distributions and traditionally more intangible factors such as preferences and private discount rates the methodology is used to develop alternate future scenarios that explore how different policy mechanisms such as fuel subsidies and micro financing can enhance the diffusion of modern more efficient energy sources in india

comprehensive evaluation of household indirect energy consumption and impacts of alternative energy policies in china by input output analysis abstract households consume a large amount of indirect energy through the consumption of goods and services this fact makes the quantitative analysis of indirect household energy consumption the foundation of energy policy design this paper improves the compilation method of energy input output tables and establishes a sequence of energy input output tables for china based on these tables the indirect energy consumption of both rural and urban households is calculated then with economic data for the year of 2005 the adjusted input output price model is applied to evaluate how the alternative energy policies impact production prices consumption prices and real income of rural and urban households through the mechanism of indirect energy consumption by using electricity as an example this research has practical implications for chinese economy the integration of energy efficiency improvements and energy prices increase serves as a means to achieve both economic and energy conservation goals and may also have a positive effect on residents real income and a minimal effect on production prices

government effectiveness and regional variation in informal employment abstract this article analyses the role of government effectiveness in the determination of informal employment a theoretical model is developed in which local governance and worker skill level are assumed to influence the decision of the worker whether to seek employment in the formal or informal sectors the model is assessed empirically using data from brazil where almost half of the urban labour force is employed informally the empirical analysis supports the predictions of the model and suggests that the probability of a worker being employed informally is lower in regions with better governance and higher average education

a quantile approach to assess the effectiveness of the subsidy policy for energy efficient home appliances evidence from rizhao china abstract a one year subsidy program for energy efficient home appliances has been implemented in china we construct a dataset consisting of participant and non participant households in both urban and rural areas of rizhao city by applying a quantile regression and counterfactual analysis this study disentangles the impact of this subsidy program and inherent household attributes on per capita residential electricity consumption first contrary to the mean regression the elasticity of electricity consumption to household s income age education and energy saving awareness varies markedly across the electricity consumption distribution and shows discrepancy between urban and rural areas second while inherent household attributes are identified as a primary determinant to the changes in residential electricity consumption the effect induced by the subsidy incentive is more significant at the middle of the electricity consumption distribution than at the tails third there are significant rebound effects that lead to overall increase in household electricity consumption our results suggest that the disparity between urban and rural regions and targeted consumer behavior changes should be taken into account to ensure the effectiveness of a future energy efficient subsidy program

on defining and measuring the informal sector evidence from brazil summary recent debate on the reasons for the informal sector has led to renewed focus on how to operationalize the measurement of informal employment this paper investigates congruence between three empirical measures of the rate of informality using brazilian household survey data for the period 1992 2004 sixty three percent of the economically active are informal according to at least one definition but only 40 are informal according to all three regression analysis is used to shed further light on differences in these measures appropriate measurement is therefore of high significance to policy analysis and design of appropriate strategies to reduce informality

investing in electricity production under a reliability options scheme abstract reliability options ros are used to enhance the security of supply in electricity systems when a power producer writes a ro s he agrees to set a cap on the price of electricity that s he cashes in return the system operator i e the party that is buying the option pays to the option issuer a fixed premium in this paper we analyze how ros affect the timing and value of investments in the energy sector and we show under what conditions they can be used as investment stimuli we prove that contrarily to what is expected ros can potentially harm the security of supply by delaying the adoption of new capacity and by reducing the value of investing in it to avoid such a result a careful setting of the relevant parameters is needed

energy efficiency subsidies with price quality discrimination abstract we compare various designs of energy efficiency subsidies in a market subject to both energy use externalities and price quality discrimination by a monopolist we find that differentiated subsidies can establish the social optimum unlike per quality regimes ad valorem regimes generate downstream interferences subsidising of the high end good leads the monopolist to reduce the quality of the low end good for this reason ad valorem differentiated rates should always decrease with energy efficiency a result seemingly at odds with actual practice in contrast with per quality differentiated subsidies the rates can increase if the externality is large enough relative to the market share of low type consumers contrary to differentiated subsidies what we shall call single instrument subsidies only achieve second best outcomes a uniform ad valorem subsidy should have a rate higher than that needed to specifically internalise energy use externalities lastly if as is often observed in practice only the high end good is to be incentivised a per quality regime should be preferred to an ad valorem one an ad valorem tax on the high end good may even be preferred to an ad valorem subsidy if the externality is small enough and low end consumers dominate the market

an empirical analysis of energy intensity and the role of policy instruments abstract the reduction of energy intensity is important for sustainable economic growth especially in non oecd countries where energy demand growth is high understanding the impact of policies on energy intensity can help policy makers to reduce energy intensity using empirical methods and cross country data from 44 countries over the period 1990 2016 we study the determinants of energy intensity the common correlated effects mean group estimator is employed since it addresses nonstationarity cross sectional dependence and heterogeneity all three of which exist in the data both gdp per capita and economy wide energy prices are shown to be negatively associated with energy intensity the empirical results provide evidence that several policy instruments are effective in reducing energy intensity i standards and labeling ii government direct investment iii strategic planning and support iv fiscal measures taxes and v grants and subsidies the duration of the policy is more important than the mere existence of the policy in demonstrating the policy s effectiveness

does renewable energy generation decrease the volatility of electricity prices an analysis of denmark and germany although variable renewable energy vre technologies with zero marginal costs decrease electricity prices the literature is inconclusive about how the resulting shift in the supply curves impacts price volatility because the flexibility to respond to high peak and low off peak prices is crucial for demand response applications and may compensate for the losses of conventional generators caused by lower average prices there is a need to understand how the penetration of vre affects volatility in this paper we build distributed lag models with danish and german data to estimate the impact of vre generation on electricity price volatility we find that in denmark wind power decreases the daily volatility of prices by flattening the hourly price profile but in germany it increases the volatility because it has a stronger impact on off peak prices our analysis suggests that access to flexible generation capacity and wind power generation patterns contribute to these differing impacts meanwhile solar power decreases price volatility in germany by contrast the weekly volatility of prices increases in both areas due to the intermittency of vre thus policy measures for facilitating the integration of vre should be tailored to such region specific patterns

the worldwide governance indicators six one or none abstract aggregate indexes of the quality of governance covering large samples of countries have become popular in comparative political analysis few studies examine the validity or reliability of these indexes to partially fill this gap this study uses factor confirmatory factor and path analysis to test both measurement and causal models of the six worldwide governance indicators they purportedly measure distinct concepts of control of corruption rule of law government effectiveness rule quality political stability and voice and accountability rather than distinguishing among aspects of the quality of governance we find that they appear to be measuring the same broad concept

residential electricity consumption in portugal findings from top down and bottom up models an econometric study of the portuguese residential electricity consumption is presented with a focus on the influence of dwelling characteristics on consumption the relationship between the dwelling and household characteristics on per capita residential electricity consumption is estimated at two different scales involving two distinct databases the first includes data at the municipality level for 2001 the second is the most recent portuguese consumer expenditure survey that was collected in 2005 and 2006 the results of the analysis at both scales are consistent and indicate that household and dwelling characteristics have a significant influence on residential electricity consumption our results show that in portugal the direct effect of income on electricity consumption is low and becomes smaller when more relevant control variables are included in the analysis future demand of electricity in portugal will be significantly influenced by trends in socioeconomic factors as well as changes in the building stock these trends should be taken in consideration in the formulation of policy measures to reduce electricity consumption

short long and spatial dynamics of informal employment di caro p and nicotra g short long and spatial dynamics of informal employment regional studies this paper analyses regional shadow labour markets cross regional migration flows are introduced in a stochastic two sector model used to study the effects of regional interactions on informality empirical results show that informal activities across italian regions are driven by the inefficient provision of public goods and high taxes regional connections are found to be significant place specific reactions of informal employment to national shocks in the official economy are investigated finding that the informal sector can act as a complement to or a substitute for formal activities the summary of the results and policy conclusions are then discussed

estimating broad brush rebound effects for household energy consumption in the eu 28 countries and norway some policy implications of odyssee data abstract currently there is a strong policy commitment in european union eu and organisation for economic co operation and development oecd countries to increase the energy efficiency of residential buildings and it is widely assumed that this will naturally and automatically reduce domestic energy consumption however other factors such as fuel prices wages attitudes and lifestyles also influence energy consumption this paper calculates broad brush rebound effects based on changes in energy efficiency and energy consumption in each of the 28 eu countries plus norway for the years 2000 2011 in doing so it tests how well the assumption of energy efficiency leading to energy reduction stands up to scrutiny in these lands it uses the eu s odyssee database for efficiency and consumption figures and a commonly employed econometric definition of the rebound effect as an energy efficiency elasticity most older eu lands show rebound effects in the expected range of 0 50 however the range for newer eu countries is 100 550 suggesting that energy efficiency increases are not a good predictor of energy consumption a more in depth look at one country germany suggests these results underestimate the rebound effect significantly this also identifies research needs for specific energy consumption determinants in each country to find more precisely what is driving consumption levels

is biomass power a good choice for governments in china abstract to fulfill the target of emissions reduction the chinese government has made many efforts to develop renewable energy biomass power can provide stable power supply avoid wasting straw resources and protect rural environment at the same time however the development of renewable power requires subsidies from the government but increased subsidies placed heavy burden on the governments whereas these governments want to develop renewable energy with minimum costs this paper attempts to answer the question that whether the development of biomass power is a good choice for local governments in china for this purpose the goal of emissions reduction and subsidies of renewable energy powers were discussed the main conclusion is that although the subsidies for biomass power were slightly higher than those for wind power biomass power is a good choice for governments considering other benefits especially for regions with rich agricultural and forest residues in the future regional and local conditions should be considered in the planning of biomass power development

representing in home and out of home energy consumption behavior in beijing abstract it is expected that in home and out of home energy consumption behavior in a household might be correlated with each other probably due to the existence of household budget constraints ownership and usage of energy saving technologies for in home appliances or vehicles might lead to the increase in out of home or in home energy consumption it is therefore necessary to jointly represent in home and out of home energy consumption in the same modeling framework with this consideration we first build a new type of energy consumption model based on the multiple discrete continuous extreme value mdcev modeling framework next we conducted a questionnaire survey in beijing in 2009 and successfully collected the information about households energy consumption ownership usage of in home appliances and vehicles and households and their members attributes from 1014 households throughout an empirical analysis it is confirmed that the mdcev model is effective to simultaneously describe the in home and out of home energy consumption behavior in addition it is revealed that a set of household and personal attributes affect the ownership and usage of in home appliances and vehicles furthermore it is shown that the unobserved factors play a much more important role in explaining energy consumption behavior than the observed attributes of households and their members

understanding the spectrum of residential energy consumption a quantile regression approach abstract residential energy consumption accounts for 22 of the total energy consumption in the us however the impacts of local planning policies such as increasing density and changing the housing type mix on residential energy consumption are not well understood using residential energy consumption survey data from the energy information administration quantile regression analysis was used to tease out the effects of various factors on entire distribution on the energy consumption spectrum instead of focusing on the conditional average results show that while housing size matters for space conditioning housing type has a more nuanced impact self reported neighborhood density does not seem to have any impact on energy use furthermore the effects of these factors at the tails of the energy use distribution are substantially different than the average in some cases differing by a factor of six some not all types of multifamily housing offer almost as much savings as reduction in housing area by 100 m 2 compared to single family houses

the size and development of the shadow economy an empirical investigation from states of india abstract using the state level data from india this paper investigates the size of the hidden economy in indian states over the period 1974 75 to 1995 96 our analysis has shown that after liberalization of the indian economy in 1991 92 the growth in the size of the hidden economy has decreased on an average our results show that the growth in the size of the hidden economy is approximately 4 less in scheduled election years than in all other years we also demonstrate that the growth is significantly lower in those states where the coalition government is in power an increased growth of newspapers and the literacy rates translate to cleaner governance e g to fewer amounts of shadow economy activities in the economy
