estimating residential demand for electricity in greece abstract this paper examines the residential demand for electricity in greece the issues of structural stability price and income sensitivity of both long and short run residential demand for electricity in greece were examined employing monthly data over the period 1986 1999 the long run residential demand for electricity is estimated taking into account changes in weather conditions weighted by the size of the population employing multivariate framework analysis a long run residential demand function for electricity sensitive to real income price level and weather conditions is found to exist and the importance of short run deviations is presented using vector error correction model vecm estimation the empirical evidence suggests the presence of a stable residential demand for electricity in greece both in the long and short run periods and the policy implications of such a relationship are presented

the changing time series properties of earnings cash flows and accruals has financial reporting become more conservative abstract this paper documents changes in the patterns of earnings cash flows and accruals over the last four decades in the absence of a generally accepted definition of conservatism a number of measures of reporting conservatism are identified and examined these measures rely on the accumulation of nonoperating accruals the timeliness of earnings with respect to bad and good news characteristics of the earnings distribution and the market to book ratio the patterns are consistent with an increase in conservative financial reporting over time the findings have implications for accounting standard setting regulation of financial information and financial statement analysis

the information content of security prices a second look abstract beaver lambert and morse 1980 employ a regression of percentage change in prices on percentage change in earnings in which data are grouped by the dependent variable reverse regression offers a more intuitive and direct way to assess the information content of security prices the objective of beaver et al while grouping is asymptotically equivalent reverse regression is a more efficient way of examining the incremental explanatory power of lagged values of percentage change in price with respect to accounting earnings

information in prices about future earnings abstract stock return over a period reflects the market s revision in expectation of future earnings accounting earnings over the same period however have limited ability to reflect such revised expectations therefore returns anticipate earnings changes and the earnings response coefficient from a regression of returns on contemporaneous earnings changes is biased toward zero we reduce this bias by including leading period returns in price earnings regressions the resulting estimated earnings response coefficient magnitudes suggest that the capital market on average views earnings changes to be largely permanent this is consistent with the random walk time series property of annual earnings

demographic change tourism expenditure and life cycle behaviour abstract the paper explores how demographic changes in human populations may impact on tourism decision making of households over their life cycle by means of hurdle models the study focuses respectively on the decision to travel domestically or abroad and investigates if statistically significant differences exist as to the impact of age and cohort on the decision to travel and tourism expenditure using a vast dataset on italian household expenditures over the period 1997 2007 the empirical results show that demographic aspects do have a strong effect on the tourism behaviour of families and that cohort and age effects act differently on the decision of households to make a trip and on how much they spend on tourism age has a negative effect on the desire to travel but a positive effect on tourism expenditure on the other hand older cohorts are inclined to travel but they have a low propensity to spend on tourism relevant differences in income elasticity along the life cycle of households have also been found finally age and cohort aspects have a different effect on the decision as to whether to travel nationally or internationally

consumer demand and the life cycle allocation of household expenditures the purpose of this paper is to estimate the parameters of household preferences that determine the allocation of goods within the period and over the life cycle using micro data in doing so the authors are able to identify important effects of demographics labor market status and other household characteristics on the intertemporal allocation of expenditure they test the validity of the life cycle model using excess sensitivity tests and find that controlling for demographics and labor market status variables can largely explain the excess sensitivity of consumption to anticipated changes in income

short and long run demand for energy in mexico a cointegration approach abstract the objective of this paper is to estimate the demands for the different types of energy consumption for the mexican economy over the period 1965 2001 these demands are modeled as a function of output and the own real price the johansen j econ dynamics control 12 1988 231 procedure and the likelihood ratio tests indicate the existence of long run and stable relationships between each type of energy demand and income with the exception of the industrial sector where the cointegrating vector also includes the relative prices the weak exogeneity tests indicate that energy consumption and income do not reject the null hypothesis of weak exogeneity when relative prices are weak exogenous the final econometric models show that relative prices in the short run are relevant in all cases with the exception of the residential sector these results indicate that in mexico the demand for energy is fundamentally driven by income and that the effect of the relative prices is basically concentrated on the short run with the exception of the industrial sector which also shows a long term price impact the strong dependence of energy consumption with respect to income and the price inelastic response indicates that it is necessary to introduce strong measures to decouple energy consumption from output in order to obtain sustainable economic growth in mexico

industrial energy substitution during the 1980s in the greek economy abstract factor substitution in greek manufacturing during the 1980s is examined using pooled data in static and dynamic translog expenditure share models inputs are capital labor electricity and non electrical energy liquid solid gas own price elasticities for capital and labor are inelastic but for electricity more elastic 0 90 results indicate substitutability among factors in the short run in the long run electricity and capital are complements as are labor and non electrical energy greek manufacturing is predicted to continue decreased consumption of liquid fuels to the year 2000 continuing the electrification begun in the 1970s

earnings skewness and analyst forecast bias abstract we argue that if analysts objective is to provide the most accurate forecast by minimizing the mean absolute forecast error then the optimal forecast is the median instead of the mean earnings forecast bias is observed when the median is different from the mean in a skewed earnings distribution thus part of the observed analyst forecast bias could be a result of analysts efforts to improve forecast accuracy when the earnings distribution is skewed we find that earnings skewness is significantly related to analyst forecast bias we also provide evidence that the market adjusts for part of the skewness induced bias

accounting conservatism and firm investment efficiency abstract we argue that conservatism improves investment efficiency in particular we predict that it resolves debt equity conflicts facilitating a firm s access to debt financing and limiting underinvestment this permits the financing of prudent investments that otherwise might not be pursued our empirical results confirm these predictions we find that more conservative firms invest more and issue more debt in settings prone to underinvestment and that these effects are more pronounced in firms characterized by greater information asymmetries we also find that conservatism is associated with reduced overinvestment even for opaque investments such as research and development

the effect of oil price increases on four oil poor developing countries a comparative analysis abstract computable general equilibrium models are used to compare for four oil poor developing countries ivory coast kenya south korea turkey the short and medium run adjustment pressures arising from the second oil price shock the results emphasize the extent of expenditure switching and expenditure and wage reduction needed to accomodate the shock in each country cross country variations in the extent of required adjustment are traced to key structural differences between the four economies

earnings quality in uk private firms comparative loss recognition timeliness abstract uk private and public companies face substantially equivalent regulation on auditing accounting standards and taxes we hypothesize that private company financial reporting nevertheless is of lower quality due to different market demand regulation notwithstanding a large uk sample supports this hypothesis quality is operationalized using basu s 1997 time series measure of timely loss recognition and a new accruals based method the result is not affected by controls for size leverage industry membership and auditor size or by allowing endogenous listing choice the result enhances understanding of private companies which are predominant in the economy it also provides insight into the economics of accounting standards

the uk consumption boom of the late 1980s aggregate implications of microeconomic evidence two competing explanations of the uk consumer boom in the late 1980s are the financial liberalisation imperfect housing market hypothesis of muellbauer and murphy and the expectations hypothesis of king we use 15 years of family expenditure surveys and cohort analysis to investigate to what extent these two hypotheses agree with observed changes in consumption patterns we find that the housing markets explanation accounts for much of the increase by older cohorts but cannot be reconciled with the marked rise in expenditure levels of younger households a simple simulation exercise shows instead that the expectations hypothesis can generate increases of expenditure by young consumers of the magnitude observed in our data

the bright side of managerial over optimism human estimation and inference are subject to systematic biases such as overconfidence and over optimism in contrast to prior research that has identified multiple negative consequences of these biases we focus on positive effects we empirically examine a setting in which over optimism a is a related but different bias from overconfidence b emerges dynamically in a rational economic framework and c generates higher managerial effort importantly this additional effort improves firm profitability and market value

the structure of residential energy demand in greece abstract this paper attempts to shed light on the determinants of residential energy demand in greece and to compare it with some other oecd countries from the estimates of the short run and long run elasticities of energy demand for the period 1965 1999 we find that residential energy demand appears to be price inelastic also we do not find evidence of a structural change probably because of the low efficiency of the energy sector we find however that the magnitude of the income elasticity varies substantially between greece and other oecd countries

enforceable accounting rules and income measurement by early 20th century railroads we investigate the extent to which income measurement by major early 20th century u s railroads shows evidence of lower income smoothness and increased conservatism following new fixed asset accounting rules issued by the interstate commerce commission icc in 1907 and 1908 and concurrent rate regulation regime shifts accounting rules promulgated by the icc after the hepburn act of 1906 are the first accounting rules in u s history in which regulators could enforce such rules under federal law to increase compliance our samplewide results are more consistent with increased conservatism than with income smoothing additional tests indicate these effects are more pronounced for firms subject to more intense rate regulation by the icc which suggests that the tie in between accounting regulation and product service market regulation influences how managers respond to new accounting rules

modeling industrial energy demand in greece using cointegration techniques abstract this paper attempts to shed light on the determinants of industrial energy demand in greece for this purpose we used cointegration analysis in order to capture short run and long run elasticities for oil and electricity industrial demand respectively the sample spans the period 1970 2004 from the empirical analysis and the johansen s maximum likelihood procedure we found cointegration for oil and electricity demand the results suggest that industrial energy demand is inelastic both in the short and the long run while electricity and oil are substitutes also oil and electricity prices are weakly exogenous both in the short and the long run

the information content of earnings and prices a simultaneous equations approach abstract the price earnings relation can be characterized as a system of simultaneous equations earnings and prices can behave as if they are both endogenously determined because they are jointly affected by information that is difficult to specify explicitly specification tests provide evidence that both earnings changes and price changes are endogenous the price and earnings coefficients increase from ols to joint estimation and under a restrictive set of assumptions provide increasingly similar estimates of the permanent component of earnings the evidence is consistent with the contention that a portion of the single equation bias can be mitigated via joint estimation

discussion of the role of accruals in asymmetrically timely gain and loss recognition the accrual process is central to financial accounting accruals adjust cash flows to reported earnings and form the building blocks for the balance sheet given the importance of accruals to financial accounting it is surprising how sparse the modeling of the overall accrual process has been within the literature until recently the state of the art empirical approach modeled total accruals as a function of the change in sales and property plant and equipment pp e jones 1991 recently working capital accruals have been more formally modeled as a function of firms selling activity and past present and future operating cash flows e g dechow kothari and watts 1998 dechow and dichev 2002 ball and shivakumar incorporate conditional conservatism an important feature of the earnings process into existing accruals models specifically they recognize that accruals are expected to be an asymmetric function of firm performance in which economic losses are captured by the accruals process in a more timely manner than gains their evidence documents a robust asymmetry in the relation between accruals and economic losses and gains and demonstrates that accruals models that incorporate this asymmetry have superior explanatory power the authors innovation advances

the demand for energy in greece assessing the effects of the community support framework 1994 1999 the paper estimates the demand for energy in greece in the tradable and non tradable sectors and for the three main types of energy namely oil electricity and solid fuel using the estimated demand functions forecasts of the demand for energy until the year 2010 are derived by incorporating the system of demand and energy price equations into a fully fledged annual macroeconometric model the model is subsequently used to forecast the demand for energy and the shares of various forms under alternative assumptions about the effects of the community support framework csf it is found that the demand for energy will be significantly affected by the presence of externalities in the implementation of csf that give rise to positive supply side effects and boost growth in the absence of supply side externalities total energy demand rises by 1 4 above the benchmark non csf scenario with growth inducing externalities total demand will increase at year 2010 by 6 0 above baseline

the information content of losses abstract this study hypothesizes that because shareholders have a liquidation option losses are not expected to perpetuate they are thus less informative than profits about the firm s future prospects the results are consistent with the hypothesis they also show that the documented increase in the earnings response coefficent as the cumulation period increases appears to be due exclusively to the effect of losses the liquidation option effect extends to profitable cases where earnings are low enough to make the option attractive alternating explanations for the low informativeness of losses such as mean reversal of earnings are not supported by the tests

management by the numbers a formal approach to deriving informational and distributional properties of unmanaged earnings we explore the theoretical relation between earnings and market returns as well as the properties of earnings frequency distributions under the assumption that managers use unbiased accounting information to sequentially decide on real options their firms have and report generated earnings truthfully with the market pricing the firm based on those reported earnings we generate benchmarks against which empirically observed earnings returns relations and aggregate earnings distributions can be evaluated this parsimonious model shows a coherent set of results reported losses are less persistent than reported gains decision making diminishes the s shaped market response to earnings and earnings relate to returns asymmetrically in the way documented by basu 1997 furthermore the implied frequency distribution of aggregate earnings is neither symmetric nor necessarily single peaked instead it may exhibit a kink at zero and look similar to the plots reported by burgstahler and dichev 1997 however within our model none of these phenomena are due to reporting noise bias or some undesirable strategic managerial behavior they are the natural consequences of using past earnings as the basis for value increasing managerial decision making that in turn generates the future earnings on which future decisions will be based

income and the substitution pattern between domestic and international tourism demand this article analyses the role of income in the decision of participating in the tourism demand within 1 year the tourists who are participating can travel to domestic destinations only abroad destinations only or to both of them such a substitution pattern is modelled using a bivariate probit model the analysis is carried out to the regional level using a survey conducted in 15 european eu 15 countries in addition to the traditional socioeconomic variables the analysis adds new variables to the outbound tourism demand modelling such as the attributes of the place of residence the results show that tourism demand is income elastic however there are marked differences in the income elasticities of the probabilities of travelling domestically or abroad above certain income threshold the substitution pattern between destinations takes part the probability of travelling domestically only remains constant whereas the probability of travelling abroad keeps growing additionally the article prov

the role of accruals in asymmetrically timely gain and loss recognition we investigate the role of accrual accounting in the asymmetrically timely recognition incorporation in reported earnings of gains and losses timely recognition requires accruals when it precedes complete realization of the gains and losses in cash we show that nonlinear accruals models incorporating the asymmetry in gain and loss recognition timelier loss recognition or conditional conservatism offer a substantial specification improvement explaining substantially more variation in accruals than equivalent linear specifications conversely conventional linear accruals models by omitting the loss recognition asymmetry exhibit substantial attenuation bias and offer a comparatively poor specification of the accounting accrual process linear specifications also understate the ability of current earnings to predict future cash flows these findings have implications for our understanding of accrual accounting and conservatism as well as for researchers estimating discretionary accruals earnings management and earnings quality

loss function assumptions in rational expectations tests on financial analysts earnings forecasts abstract prior research concludes that financial analysts do not process public information efficiently in generating their earnings forecasts the ordinary least squares ols regression based tests used in prior studies assume implicitly that analysts face a quadratic loss function in contrast we argue that analysts likely face a linear loss function and hence try to minimize their absolute forecast errors we conduct and compare rational expectations tests using these two alternative loss functions we reproduce most prior findings of forecast inefficiency with ols regressions but find virtually no evidence of forecast inefficiency with least absolute deviation regressions where we explicitly assume a linear loss function

holiday taking and income this paper is the first attempt to estimate the determinants of holiday taking across several countries to accomplish this a two stage estimation procedure is employed which enables incongruous income categories to be transformed into a single income variable it is found that in the mid 1980s there was a substantial similarity in the holiday taking behaviour of europeans the large national differences in holiday participation are explained by differences in income and demographic factors a remarkable regularity in the responsiveness of the probability of holiday taking to marginal changes in income is found

energy consumption and economic growth a causality analysis for greece abstract this paper investigates the causal relationship between aggregated and disaggregated levels of energy consumption and economic growth for greece for the period 1960 2006 through the application of a later development in the methodology of time series proposed by toda and yamamoto 1995 at aggregated levels of energy consumption empirical findings suggest the presence of a uni directional causal relationship running from total energy consumption to real gdp at disaggregated levels empirical evidence suggests that there is a bi directional causal relationship between industrial and residential energy consumption to real gdp but this is not the case for the transport energy consumption with causal relationship being identified in neither direction the importance of these findings lies on their policy implications and their adoption on structural policies affecting energy consumption in greece suggesting that in order to address energy import dependence and environmental concerns without hindering economic growth emphasis should be put on the demand side and energy efficiency improvements

deconstructing life cycle expenditure we revisit two well known facts regarding life cycle expenditures the hump shaped profile of nondurable expenditures and the increase in cross household consumption inequality we document that the behavior of total nondurables masks surprising heterogeneity in the life cycle profile of individual consumption subcomponents we provide evidence that the categories driving life cycle consumption either are inputs into market work or are amenable to home production using a quantitative model we document that the disaggregated life cycle consumption profiles imply a level of uninsurable permanent income risk that is substantially lower than that implied by a model using a composite consumption good

estimation and empirical properties of a firm year measure of accounting conservatism we estimate a firm year measure of accounting conservatism examine its empirical properties as a metric and illustrate applications by testing new hypotheses that shed further light on the nature and effects of conservatism the results are consistent with the measure c score capturing variation in conservatism and also predicting asymmetric earnings timeliness at horizons of up to 3 years ahead cross sectional hypothesis tests suggest firms with longer investment cycles higher idiosyncratic uncertainty and higher information asymmetry have higher accounting conservatism event studies suggest increased conservatism is a response to increases in information asymmetry and idiosyncratic uncertainty

the application of generational theory to tourism consumer behavior an american perspective abstract the purpose of this study was to examine the attitudes and behaviors of american international travelers using a generational analysis based on woodside and dubelaar 2002 s theory of tourism consumption systems tcs five hypotheses were proposed regarding tourists information source preferences destination visitation history future destination preferences destination evaluation criteria and travel activity preferences the study utilized chi square and anova tests to detect statistically significant differences among generations additionally two perceptual mapping techniques correspondence analysis and multidimensional scaling analysis were employed to graphically discern the relationships between generations and the variables of interest the results support all five hypotheses revealing not only a number of significant differences among generations but also some important similarities the study provides important empirical support for the theory of tcs whilst showing the value of generational analysis as a commonsense segmentation criterion in travel market research

empirical assessment of the determinants of road energy demand in greece this paper attempts to cast light on the determinants of road energy demand in greece for this purpose we used cointegration techniques and vector autoregression var analysis in order to capture short run and long run dynamics for gasoline and diesel demand respectively from the empirical analysis that covers the period 1978 2003 we find that in the long run gasoline energy demand appears to be price and income inelastic while diesel demand appears to be price inelastic and income elastic we also found that the absence of close substitutes in the road sector denotes the low level of energy switching in greece

uncertainty resolution and the theory of depreciation measurement this paper examines how a firm s depreciation policy influences the relation between the resulting accounting numbers and the market value of the firm s equity traditional financial accounting theory conceptualizes depreciation measurement as a cost allocation procedure that matches an investment s cost with the flow of benefits it produces as has long been recognized in a setting with certain future cash flows and zero net present value npv investments investment costs can be allocated using standard present value techniques to yield at each date book values equal to market values and accounting earnings equal to economic earnings 2 the resulting book value and accounting earnings numbers are such that for all periods the book rate of return equals the cost of

humps and bumps in lifetime consumption in this article we argue that the life cycle model that allows demographics to affect household preferences and relaxes the assumption of certainty equivalence can generate hump shaped consumption profiles over age that are very similar to those observed in household level data sources and in particular match the differences in shape across different education groups liquidity constraints or myopia are not required to explain the empirical features of observed life cycle patterns

the demand for energy in greek manufacturing abstract this paper considers an econometric approach to measuring substitutability of three types of energy i e crude oil electricity and diesel with capital and labour in the manufacturing sector of greek industry during the period 1970 1990 a general dynamic framework is developed under the assumption that the structure of the production process is weakly separable in capital labour and energy aggregates the translog total cost function is used to represent the production technology the main advantages of the proposed dynamic structure are that it is both disaggregated in energy components and consistent with the neo classical theory of production

tourism participation and expenditure by spanish households the effects of the economic crisis and unemployment abstract this paper examines household tourism participation decisions and tourism expenditure across the business cycle microdata is used from the spanish household budget survey for the years 2006 2010 facilitating an analysis of the consequences of the economic crisis and unemployment on tourism consumption decisions by households by estimating a heckman model the effects of households socioeconomic determinants on participation and expenditure decisions can be identified taking the year 2008 the beginning of the crisis as a reference the stability of the tourism expenditure model is tested identifying variables whose effects alter in times of crisis one important aspect of the study is how household unemployment affects tourism participation and expenditure decisions the effect of unemployment takes into account whether it is the main breadwinner his or her spouse or another member of the household who is unemployed concentrating on those households whose main breadwinner was employed at the time an analysis is also made of how job insecurity affects tourism consumption decisions from the results the unemployment variables can be seen to have a significant explanatory power suggesting that unemployment information does help to explain the evolution of tourism expenditure across the business cycle

estimating and testing the compensated double log demand model in spite of the proliferation of flexible functional forms for consumer demand systems the double log demand model continues to be popular especially in applied work calling for single equation models it is usually estimated in uncompensated form it can also be estimated in compensated form by deflating the income variable alone using stone s price index the compensated form has the same right hand side as a single equation version of the popular linear approximation to the almost ideal demand model facilitating the construction of a test for choosing between the two alternatives this paper demonstrates these results develops the specification test and illustrates its application using us meat consumption data simulations suggest that the test is well behaved with good power in typical applications

energy demand and environmental taxes the case of greece the purpose of this paper is to analyze the effects that energy taxes may have on reducing environmental pollution in greece we study the demand for residential energy for the period 1965 1998 and on the basis of these estimates we make forecasts for co2 emissions in the coming years furthermore we develop alternative scenarios for tax changes and study their effects on co2 emissions according to our findings the harmonization of the greek energy taxes to the average european union levels implies an increase of total co2 emissions by 6 annually if taxes are raised however to the highest european union levels the co2 emissions are restricted significantly these empirical findings may indicate that environmental taxation cannot be the unique instrument for combating pollution

energy consumption and economic growth assessing the evidence from greece abstract this paper attempts to shed light into the empirical relationship between energy consumption and economic growth for greece 1960 1996 employing the vector error correction model estimation the vector specification includes energy consumption real gdp and price developments the latter taken to represent a measure of economic efficiency the empirical evidence suggests that there is a long run relationship between the three variables supporting the endogeneity of energy consumption and real output these findings have important policy implications since the adoption of suitable structural policies aiming at improving economic efficiency can induce energy conservation without impeding economic growth

a review of innovation research in tourism abstract over the past two decades there has been increasing focus on the topic of innovation in tourism this article reviews the research contributions various categories of innovation product process managerial marketing and institutional are addressed important determinants of innovation are acknowledged including the role of entrepreneurship technology push and the existence of territorial industry clusters representation of knowledge is also identified as a critical factor for both the occurrence and nature of innovations the review reveals that there is still only limited systematic and comparable empirical evidence of the level of innovative activities and their impacts and wider implications for destinations and national economies an agenda for future research is emerging suggesting that there is quest for both formal quantification and for qualitative studies of the foundations processes implications and policies of innovation in tourism

asymmetric sensitivity of ceo cash compensation to stock returns abstract we document that ceo cash compensation is twice as sensitive to negative stock returns as it is to positive stock returns since stock returns include both unrealized gains and unrealized losses we expect cash compensation to be less sensitive to stock returns when returns contain unrealized gains positive returns than when returns contain unrealized losses negative returns this is consistent with boards of directors exercising discretion to reduce costly ex post settling up in cash compensation paid to ceos

investment dynamics and earnings return properties a structural approach we propose the standard neoclassical model of investment under uncertainty with short run adjustment frictions as a benchmark for earnings return patterns absent accounting influences we show that our proposed benchmark generates a wide range of earnings return patterns documented in accounting research notably our model generates a concave earnings return relation similar to that of basu 1997 and predicts that the earnings return concavity increases with the volatility of firms underlying shock processes and decreases with the level of firms investments we find strong empirical support for these predictions overall our evidence suggests that our proposed benchmark is useful for understanding the joint dynamics of variables of interest to accounting research e g earnings returns investment market to book absent accounting influences a necessary precondition for inferring the effects of accounting from these dynamics

an analysis of households appraisal of their budget constraints for potential participation in tourism abstract this paper examines the importance of households budget constraints as a barrier to participation in tourism for this purpose a sample of spanish households drawn from the european community household panel was analysed this survey gathers data on the economic and socio demographic situation of all adult household members more specifically it includes a question on each household s capacity to afford a week s yearly holiday the aim of this question is to assess whether households have sufficient financial resources to participate in tourism the results of the analysis demonstrate that budget constraints on tourist travel are binding for a significant percentage of spanish households the results also show that this type of constraint is not only conditioned by the level of income but by a more complex appraisal that also includes other financial variables such as households saving capacity or the unemployment status of its members furthermore non financial variables such as the level of education age and barriers associated with poor health status all help to determine the degree of importance with which households perceive their budget constraints

statistical models for zero expenditures in household budgets household budget surveys are an important source of data on consumer s expenditure not just for individual consumers but also for estimating national aggregates however it is a widespread finding that for certain commodities most notably tobacco and alcohol the estimate from the household survey falls short of the known consumption total calculated with some confidence from data on production imports exports and excise duties for example in the british family expenditure survey with which we shall largely be concerned total tobacco expenditure was underestimated in 1976 by 21 percent see kemsley redpath and holmes 1980 p 51 much of this understatement together with that on alcohol is thought to occur because of the design of the survey which excludes many persons amongst whom consumption of such items is thought to be atypically high e g prisoners hoteliers and their residents merchant seamen even so the possibility remains that some of the understatement is due to various types of misreporting by households included in the survey in this paper we consider a model in which the standard tobit specification tobin 1958 is supplemented by the operation of a simple binary censor the tobit model is essentially a linear regression model in which non positive observations of the dependent variable are replaced by zero we take this specification as our starting point but add a second censoring process that randomly replaces a fraction of the observations generated by the tobit model bv zeroes the combined model can serve as a representation of several types of

the electricity consumption and economic growth nexus evidence from greece abstract this paper attempts to cast light into the relationship between electricity consumption and economic growth in greece in a multivariate framework for this purpose we used cointegration techniques and the vector error correction model in order to capture short run and long run dynamics over the sample period 1970 2011 the empirical results reveal that in the long run electricity demand appears to be price inelastic and income elastic while in the short run the relevant elasticities are below unity we also argue that the causal relationship between electricity consumption and economic growth in greece is bi directional our results strengthen the notion that greece is an energy dependent country and well directed energy conservation policies could even boost economic growth furthermore the implementation of renewable energy sources should provide significant benefits ensuring sufficient security of supply in the greek energy system this evidence can provide a new basis for discussion on the appropriate design and implementation of environmental and energy policies for greece and other medium sized economies with similar characteristics

oil price shocks stock market economic activity and employment in greece abstract using a multivariate vector autoregression var approach this paper attempts to shed light into the dynamic relationship among oil prices real stock prices interest rates real economic activity and employment for greece the empirical evidence suggests that oil price changes affect real economic activity and employment oil prices are important in explaining stock price movements stock returns do not lead to changes in real activity and employment

residential demand for electricity the case of greece this paper examines the determinants of residential electricity consumption in greece over the period 1961 86 the paper presents first a brief description of the evolution of residential electricity consumption then it proceeds in the estimation of elasticities of residential demand for electricity using a single equation model with the ridge regression method the paper concludes that i the residential demand for electricity is price inelastic and income elastic ii there is high substitutability between electricity and lpg iii during the examined period the number of consumers played a very important role in the expansion of electricity consumption in greece and iv there is no regional variation in residential electricity demand

asymmetric timeliness of earnings market to book and conservatism in financial reporting abstract using an accounting conservatism theory that reflects accounting s role in practice we investigate the relation between two extensively used measures of conservatism asymmetric timeliness of earnings and the market to book ratio mtb we predict and observe that when asymmetric timeliness is measured cumulatively over long periods its relation with end of period mtb is positive when asymmetric timeliness is measured over short periods its dependence on beginning of period composition of equity value ev is responsible for its negative association with mtb further asymmetric timeliness appears to measure conservatism more efficiently when it is estimated cumulatively over multiple periods

energy price shocks in the 1970s impact on industrialized economies abstract the energy price increases in the 1970s profoundly affected the major macroeconomic variables in the economies of the industrialized world this article measures the magnitude of the effect of the 1973 energy price shock on the economies of the usa canada the uk germany and france a short run model of aggregate supply is developed estimated and tested for overall performance and then calibrated to the experience of the 1973 1979 period a positive feature of the model is that it adopts a generalized multisector framework in which an energy sector is explicitly introduced in construction of the aggregate supply function the model also heeds labour market rigidities according to the model the 1973 leap in energy prices generated a major inflationary impulse in all of the countries studied the effects on labour productivity real wages capital utilization rate and energy consumption were also found to be considerable and to a large degree similar an interesting result concerning labour demand is that higher energy prices led to substitution of labour intensive methods of production for energy intensive ones raising the magnitude of the labour output ratio

a micro econometric analysis of vacation behaviour we present a micro econometric limited dependent variable model which simultaneously explains the decision whether to go on vacation or not the choice of destination and the decision on the level of the vacation expenditures the model has been estimated on the basis of a cross section of dutch households we find a striking difference in income elasticity between domestic vacations and vacations abroad and a large impact of owning certain durables such as a boat on the choice of destination to illustrate the potential of the model some simulations are performed

association between accounting performance measures and stock prices a test of the life cycle hypothesis abstract this paper posits that stock market response to two accounting performance measures sales growth and capital investment is a function of firm life cycle stage firms are grouped into various life cycle portfolios using dividend payout sales growth and age as predicted the empirical results indicate a monotonic decline in the response coefficients of unexpected sales growth and unexpected capital investment from the growth to the stagnant stages additional analysis suggests that this relation is not driven by a firm size effect risk differences or measurement error in the proxies for performance measures

micro economic determinants of tourist expenditure a quantile regression approach abstract we assess the effect of the main determinants of tourist expenditure by applying both linear and quantile regression models to individual micro data collected by a survey addressed to non resident tourists who spent their holidays in sardinia during the period april october 2012 we find that in addition to income and foreign nationality tourist expenditure is crucially driven by trip related party size stay length accommodation sea and sun typology and transport modality and psychographic characteristics repeated visits and holiday motivations moreover our results indicate that the effects vary with respect to the expenditure component and the level of spending thus confirming the high complexity of the tourism product higher positive effects were found for heavy spenders in the case of foreign nationality previous visits and notoriety motivated holidays while party size and the number of visited sites contribute to reducing the level of expenditure for light spending tourists

international differences in the timeliness conservatism and classification of earnings in this paper we analyze differences in the timeliness of income recognition between the u s and u k gaap financial reporting regimes building on previous work in the area we focus on the links between current reported earnings and current and past changes in market value in the light of basu 1997 we present a formal model in which the response of reported earnings to changes in market value varies according to whether the value change is good news or bad this model yields a number of insights with regard to the definition and measurement of earnings conservatism we also report evidence indicating that controlling for cross jurisdictional classification differences affects comparisons of earnings timeliness and earnings conservatism specifically we find that apparent differences in conservatism between the u s and u k accounting regimes are sensitive to the inclusion or exclusion of extraordinary items in u k accounting earnings recent research documents significant variation in the information content of earnings across international gaap regimes e g alford et al tlancaster university tuniversity of manchester the research support of the eco

parametric and semi parametric modelling of vacation expenditures we analyse several limited dependent variable models explaining the budget share that dutch families spend on vacations to take account of the substantial number of zero shares two types of models are used the first is the single equation censored regression model we estimate and test several parametric and semi parametric extensions of the tobit model second we consider two equation models in which the participation decision and the decision on the amount to spend are treated separately the first decision is modelled as a binary choice model the second as a conditional regression we estimate and test parametric and semi parametric specifications

discussion of an economic framework for conservative accounting and bushman and piotroski 2006 abstract we offer an economic framework for generating predictions about the demand for conservative accounting reports we define conservatism as more timely recognition of losses than gains as a result of the costs and benefits of reporting verifiable information by managers and or firms being asymmetric we also discuss bushman and piotroski s interpretation of the speeds of good news recognition and incremental bad news recognition in basu type regressions as separate signals about accounting conservatism finally we suggest avenues for future research that seeks to investigate the links between institutions and contracts and between contracts and conservatism

energy demand in greece abstract this paper examines the impact of the two energy crises 1973 74 and 1978 79 on energy demand in greece initially some specific characteristics of energy consumption patterns before and after 1973 are presented and compared then demand parameters for hydroelectric energy liquid fuels and solid fuels were estimated using data for the period 1963 1984 and alternative econometric methods ols 2sls fiml to ensure that estimates do not vary across different estimation methods appropriate tests were used to examine whether a structural change in energy demand has occured following either of the two crises the results indicate that while consumption patterns may be different due to price and income changes after the crises the parameters of energy demand in greece have remained unchanged

forecasting energy consumption and energy related co2 emissions in greece an evaluation of the consequences of the community support framework ii and natural gas penetration abstract this study seeks to assess the future demand for energy and the trajectory of co2 emissions level in greece taking into account the impact of the community support framework csf ii on the development process and the penetration of natural gas which is one of the major csf ii interventions in the energy system demand equations for each sector of economic activity traded non traded public and agricultural sector and for each type of energy oil electricity and solid fuels are derived the energy system is integrated into a fully developed macroeconometric model so that all interactions between energy prices and production factors are properly taken into account energy co2 forecasts are then derived based on alternative scenarios for the prospects of the greek economy according to the main findings of the paper the growth pattern of forecast total energy consumption closely follows that of forecast output showing no signs of decoupling as regards co2 emissions they are expected to increase with an annual average rate which is higher than world forecasts

asymmetric timely loss recognition adverse shocks to external capital and underinvestment evidence from the collapse of the junk bond market abstract using the collapse of the junk bond market in the early 1990s as an exogenous shock to external capital i document in both difference in differences and triple difference designs that speculative grade firms that recognize economic losses in a timely manner experience a smaller reduction in investment following the collapse the effect is more pronounced for speculative grade firms with a low level of asset liquidation value using the excess bond premium as a proxy for fluctuations in the supply of capital i also extend the generalizability of my findings to a broader sample of 84 421 firm years over the 1972 2011 period

a double hurdle analysis of travel expenditure baby boomer seniors versus older seniors abstract this study examined the socio demographic and economic determinants of leisure travel expenditure and compared these determinants in baby boomer senior households and older senior households in the united states unlike previous studies this study performed heckman s double hurdle analysis using the consumer expenditure survey ces to present a two step process for making travel consumption decisions the results revealed that more baby boomer senior households participated in leisure travels than older senior households however among those households that chose to travel the mean expenditure of the older senior group was higher than for baby boomers this study also showed similarities and differences in the determinants of travel consumption decisions between baby boomer seniors and older seniors this two step approach provided in depth information on the processes involved in deciding to travel and how much to spend on travel this additional information will be valuable in understanding senior consumers in the tourism industry

cash flow asymmetry causes and implications for conditional conservatism research earnings asymmetric timeliness captures both accrual and operating cash flow cfo asymmetric timeliness because recognition of operating cash flows does not reflect differential verification thresholds for recognizing unrealized gains versus losses cfo asymmetry adds noise or bias to tests of conditional conservatism we show that cfo asymmetry is predictable in the cross section and varies systematically with life cycle characteristics removing cfo from earnings and using accruals based measures of asymmetric timeliness eliminates several biases that prior studies have attributed to other sources moreover accrual asymmetric timeliness varies in the cross section as theory predicts going forward we recommend researchers use accruals based asymmetric timeliness measures when testing for conditional conservatism

estimating energy conservation patterns of greek households abstract this paper develops an empirical model to investigate the main determinants of household energy conservation patterns in greece employing cross section data in the empirical analysis household energy conserving choices models are employed using a discrete and a latent trait variable respectively as a dependent variable the results show that socio economic variables such as consumers income and family size are suitable to explain differences towards energy conservation preferences in addition the results suggest that electricity expenditures and age of the respondent are negatively associated with the number of energy conserving actions that a consumer is willing to adopt finally other variables such as environmental information feedback and consciousness of energy problems are characteristics of the energy saver consumer by evaluating consumer s decision making process with regards to energy conservation measures we are able to formulate and propose an effective energy conservation framework for greece an energy policy framework is among the main prerequisites not only to achieve sustainable development but also to maintain consumers quality of life

econometrics of the basu asymmetric timeliness coefficient and accounting conservatism a substantial literature investigates conditional conservatism defined as asymmetric accounting recognition of economic shocks news and how it depends on various market political and institutional variables studies typically assume the basu 1997 asymmetric timeliness coefficient the incremental slope on negative returns in a piecewise linear regression of accounting income on stock returns is a valid conditional conservatism measure we analyze the measure s validity in the context of a model with accounting income incorporating different types of information with different lags and with noise we demonstrate that the asymmetric timeliness coefficient varies with firm characteristics affecting their information environments such as the length of the firm s operating and investment cycles and its degree of diversification we particularly examine one characteristic the extent to which unbooked information such as revised expectations about rents and growth options is independent of other information and discuss the conditions under which a proxy for this characteristic is the market to book ratio we also conclude that much criticism of the basu regression misconstrues researchers objectives

what do we learn about consumer demand patterns from micro data the aim of this paper is to assess the importance of using micro level data in the econometric analysis of consumer demand to do this we utilize a time series of repeated cross sections covering some 4 000 households in each of 15 years employing a number of different aggregation procedures we conclude that aggregate data alone are unlikely to produce reliable estimates of structural price and income coefficients however once certain aggregation factors as well as trend and seasonal components are included an aggregate model is not necessarily outperformed across all demand equations in terms of forecasting ability jel d12 c52 c31 the purpose of this paper is to develop a complete consumer demand system based on a time series of individual household data and to use it to measure the biases introduced into the study of consumer de mand behavior when aggregate data are used in place of the appropriate microeco nomic data we assess the suitability of ag gregate data through the impact on income and price elasticities and by evaluating the ability of both micro and aggregate based models to forecast aggregate consumer de mand the biases introduced by the use of aggregate data depend upon the way that household characteristics interact with in come and price effects and on departures of demand systems from linearity we explore the structure of microeconomic demand sys tems and the role of household characteris tics in the behavior of consumer demand both for the light this may shed on the pattern of future demands and for the im plications this behavior has for issues of aggregation consumer demand patterns typically found in micro data sets vary considerably across households with different household characteristics and with different levels of income we model this variability by making intercept and slope parameters in the budget share equations of our demand sys tem depend on household characteristics and by allowing for nonlinear total log expenditure terms in fact in theory consistent demand systems it is total ex penditure rather than disposable income that is allocated across goods we find that this general framework leads to a well specified data coherent demand system which is a quadratic extension of the popu lar almost ideal model of angus s deaton and john muellbauer 1980 the micro level estimates are shown to be sensitive to the treatment of endogeneity of total expen diture and to the specification of interaction terms with household characteristics in ad dition this specification is also shown to possess many attractive features for the evaluation of aggregate models

why are losses less persistent than profits curtailments vs conservatism it is well documented that losses are less persistent than profits and that stock prices anticipate the lower persistence of losses yet the underlying explanation for these results is unclear one explanation lies in the abandonment option whereby firms with losses are more likely to curtail operations e g hayn hayn c 1995 the information content of losses j accounting econom 20 2 125 153 another explanation involves timely loss recognition stemming from conservative accounting e g basu basu s 1997 the conservatism principle and the asymmetric timeliness of earnings j accounting econom 24 1 3 37 we provide direct evidence that curtailments are an important factor contributing to the lower persistence of losses an implication of our results is that popular measures of conservatism such as the measure proposed by basu also reflect curtailments this paper was accepted by suraj srinivasan accounting
