financial dollarization short run determinants in transition economies this paper examines the determinants of financial dollarization in transition economies from a short run perspective using aggregate monthly data of deposit and loan dollarization we study the drivers of short term fluctuations in dollarization and test their importance at different levels of dollarization the results provide evidence that a the positive negative short run effects of depreciation monetary expansion on deposit dollarization are exacerbated in high dollarization countries b short run loan dollarization is mainly driven by banks matching of domestic loans and deposits currency matching of assets and liabilities international financial integration and institutional quality and c both types of short run dollarization are affected by interest rate differentials and deviations from desired dollarization

substitution in the electric power industry an interregional comparison in the eastern us abstract the electric power industry is restructuring as regulations move from states to regional and national levels estimates of regional fuel and input substitution are essential for practitioners and policy makers this paper estimates substitution under static and dynamic scenarios examining changes in technology and total factor productivity from 2001 to 2008 two stage estimation reveals regional characteristics and underlying elements in fuel and factor choice processes substitution varies widely depending on the region coal technology capital investment and r d activities

social interaction co worker altruism and incentives social interaction with colleagues is an important job attribute for many workers to attract and retain workers managers therefore need to think about how to create and preserve high quality co worker relationships this paper develops a principal multi agent model where agents do not only engage in productive activities but also in social interaction with their colleagues which in turn creates co worker altruism we study how financial incentives for productive activities can improve or damage the work climate we show that both team incentives and relative incentives can help to create a good work climate

financial dollarization the role of foreign owned banks and interest rates abstract why in many economies households and firms borrow and make deposits in foreign currency expanding on the existing literature our framework addresses this question allowing for interest rate differentials and access to foreign funds to play a role in explaining this process of asset substitution or financial dollarization using a newly compiled data set on transition economies and employing a standard panel as well as a panel var methodology we find that increasing access to foreign funds leads to higher credit dollarization while it decreases deposit dollarization interest rate differentials matter for the dollarization of both loans and deposits

the effect of deregulation on us fossil fuel substitution in the generation of electricity abstract fossil fuels produce the majority of electricity in the us with coal being by far the most popular fuel used in the past regulation in the natural gas market in the form of well head price controls and under the boiler fuel use restrictions distorted fuel use away from natural gas more recently with deregulation in the natural gas industry these restrictions have been repealed which has changed fuel use patterns to measure the short run fuel use response from regulatory and other market changes we estimate interfuel substitution using two flexible functional forms the translog and the logit on monthly data from 1991 to 1993 in both models we find coal demand has the least elastic price response while gas and oil demand have the highest both models also suggest there is substitution across fuels in the short run but the patterns and magnitudes vary from comparisons with earlier studies fuel use price response is also found to vary across market conditions and regulatory regime

separability functional form and regulatory policy in models of interfuel substitution abstract counter intuitive results such as positive own price elasticities have been found in some studies of interfuel substitution this paper examines three possible reasons for this problem first including energy materials in petroleum and coal aggregates is found to contribute to incorrect signs second the mathematical properties of the translog function contribute to concavity violations in contrast the linear logit model of cost shares is found to provide more sensible estimates of own price elasticities across alternative model specifications finally natural gas curtailment policies and environmental regulations are found to be significant factors influencing us industrial fuel demand although omission of these factors does not directly contribute to curvature violations

are women more attracted to co operation than men we conduct a real effort experiment where participants choose between individual compensation and team based pay in contrast to tournaments we find that women choose team based pay at least as frequently as men in all our conditions and significantly more often in a well defined subset of conditions women s greater attraction to co operative incentives results in part from their more optimistic assessments of their prospective teammate s ability women also respond differently to alternative rules for team formation in a manner that is consistent with advantageous inequity aversion in contrast men show a greater responsiveness to efficiency gains associated with team production

peer pressure and partnerships partnerships and profit sharing are often claimed to motivate workers by giving them a share of the pie but in organizations of any significant size the free rider effects would seem to choke off

capital markets and the exchange rate with special reference to the dollarization debate in latin america the paper reviews the main challenges faced by policymakers in emerging market economies em in light of recent financial crises and taking into account salient factors like the existence of partial dollarization imperfect credibility weak financial systems and contagion the standard theory of optimal currency areas is discussed and criticized for omitting the above factors when these factors are taken into account an extreme foreign exchange regime like dollarization is shown to become much more attractive the paper discusses the pros and cons of dollarization and among other things shows that the lack of a lender of last resort is not necessarily a major drawback in em the paper also discusses inflation targeting it in a formal model it is shown that it could be subject to credibility problems similar to those found in exchange rate based stabilization programs

optimal incentive contracts under inequity aversion we analyze the classic moral hazard problem with the additional assumption that agents are inequity averse the presence of inequity aversion alters the structure of optimal contracts when the concern for equity becomes more important there is convergence towards linear sharing rules the sufficient statistics result is violated depending on the environment contracts may be either overdetermined i e include non informative performance measures or incomplete i e neglect informative performance measures finally our model delivers a simple rationale for team based incentives implying wage compression 2010 elsevier inc

the exchange rate regime and the currency composition of corporate debt the mexican experience abstract this paper analyzes the effect that the change from a fixed to a floating exchange rate regime that took place in mexico in december 1994 had on the currency composition of corporate debt in particular the paper asks whether a fixed exchange rate regime biases corporate borrowing towards foreign currency due to an implicit exchange rate guarantee given by the government therefore under a predetermined regime firms will not fully internalize their exchange rate risk and will be more likely to engage in balance sheet mismatches than under a floating regime we study the main determinants of foreign currency borrowing of those firms listed in the mexican stock exchange from 1992 to 2000 to test whether balance sheet currency mismatches fell after the adoption of the floating exchange rate regime the results found support the view that the floating exchange rate regime has been useful in reducing exchange rate exposure

is coal desulphurisation worthwhile evidence from the market abstract the paper develops a forward looking way to estimate the economic benefits of research and development on coal desulphurisation the methodology makes use of survey based techniques pioneered in environmental economics the empirical results illustrate the difficulty of configuring desulphurised coal to meet the requirements of existing electricity generating plants in addition to estimating the returns to investment in coal desulphurisation the contributions of the paper are in extending survey based valuation to meet the needs of r d investors for intelligence about the prospective value of their investments and using robust estimation techniques to reduce the influence of outliers

why do firms default on their foreign currency loans the case of hungary abstract i isolate the effect of the choice of foreign currency on the loan performance of firms borrowing in different currencies in crisis times i use a novel micro level dataset from hungary to decompose the factors contributing to the worse loan performance of foreign currency borrowers compared to local currency debtors i find that foreign currency denomination can worsen loan performance considerably while selection also contributes significantly to the default differences on the one hand per se less creditworthy firms borrowed in foreign currency and during the crisis the foreign currency shocks further weakened their loan performances on the other hand more creditworthy firms that were also well prepared for the currency risks also borrowed in foreign currency my results suggest that not the institution of foreign currency lending per se that should be blamed for the bad loan performance of foreign currency borrowers instead one should consider the characteristics of the borrowers

interfuel substitution in us electricity generation ongoing changes in the us electricity market include restructuring and increased competition with this unfettering of the market the fuel choice in generation is expected to become more flexible and responsive to investigate this hypothesis studies of us electricity fuel choices over the last three decades are summarized and the most recent analysis is provided on a market very different from the one on which earlier studies were done modern data handling techniques allow the consideration of the most comprehensive database including 185 utilities on monthly data for 1993 this paper finds fuel choice to show a considerable amount of price responsiveness the amount of responsiveness is sensitive to the fuel substitution possibilities within the utility and the amount of responsiveness seems to have increased recently for oil and natural gas

a dynamic analysis of interfuel substitution in u s industrial energy demand using data for 1960 92 to analyze interfuel substitution in the u s industrial sector a dynamic linear logit model is shown to provide superior global properties than a comparable dynamic translog model confirming earlier static results by t j considine 1989 the linear logit model provides a direct unbiased estimate of the rate of dynamic adjustment indicating a median response lag of less than two years excluding fuels used for nonenergy purposes yields larger estimates of the price elasticities for coal and oil and indicates generally greater potential for interfuel substitution than when using aggregate data

substitution between clean and dirty energy inputs a macroeconomic perspective in macroeconomic models the elasticity of substitution between clean and dirty energy inputs within the energy aggregate is a central parameter in assessing the necessary conditions for long run green growth using new sectoral data in a panel of 26 countries we formulate specifications of nested constant elasticity of substitution production functions that allow estimating this parameter for the first time we present evidence that it significantly exceeds unity a favorable condition for promoting green growth

a dynamic analysis of interfuel substitution for swedish heating plants abstract this paper estimates a dynamic model of interfuel substitution for swedish heating plants we use the cost share linear logit model developed by considine and mount considine t j mount t d 1984 the use of linear logit models for dynamic input demand systems review of economics and statistics 66 434 443 all estimated own price elasticities are negative and all cross price elasticities are positive the estimated dynamic adjustment rate parameter is small however increasing with the size of the plant and time indicating fast adjustments in the fuel mix when changing relative fuel prices the estimated model is used to illustrate the effects of two different policy changes

peers at work we study peer effects in the workplace specifically we investigate whether how and why the productivity of a worker depends on the productivity of coworkers in the same team using high frequency data on worker productivity from a large supermarket chain we find strong evidence of positive productiv ity spillovers from the introduction of highly productive personnel into a shift worker effort is positively related to the productivity of workers who see him but not workers who do not see him additionally workers respond more to the presence of coworkers with whom they frequently interact we conclude that social pressure can partially internalize free riding externalities that are built into many workplaces jel j24 l81 m54

borrowing in foreign currency austrian households as carry traders household borrowing in a foreign currency is a widespread phenomenon in austria thirteen percent of austrian households report their housing loan to be denominated in foreign currency mostly swiss franc yet despite its importance peculiar character and acute policy concerns we know little about the attitudes and characteristics of the households involved in this type of carry trade we analyze a uniquely detailed financial wealth survey of 2556 austrian households to sketch a comprehensive profile of the attitudes and characteristics of the households involved we employ both univariate tests and multivariate multinomial logit models the survey data suggest that risk seeking affluent and married households are more likely to take a housing loan in a foreign currency financially literate or high income households are more likely to take a housing loan in general these findings partially assuage policy concerns about household default risk on foreign currency housing loans or household retirement security

regional differences in nuclear and fossil fuel generation of electricity previous research on electric gen eration costs has mainly relied on economy wide data this study disaggregates a broad sample into regions known to have marked differences in fossil fuel availability climate regulatory ef fects and other variables we find differences exist in generation costs among the studied re gions and nuclear power using estimates of scale economies and other measures we also find smaller minimum efficient size fossil fuel firms than previous studies based on recent cost information this study provides insights into several industry structure issues such as capac ity expansion competition input costs environ mental policy and transmission access jel q42

electric utilities fuel use and responsiveness to fuel prices this research tests the impact of changes in fuel price to explain fuel use by electric utilities we employ a three stage least squares model that explains changes in fuel use as a function of changes in three fuel prices this model is repeated across sub samples of data aggregated at the plant level and operating holding company level we expect that plants and holding companies reduce fuel use when fuel prices rise several fuel substitution effects within and across plants and holding companies are demonstrated as well as several frictions at the plant level higher prices of natural gas lead to less natural gas consumption less coal consumption and more fuel oil consumption at the operating holding company level results demonstrate the inelasticity of coal use and the increases of natural gas in response to higher coal prices subsamples demonstrate heterogeneity of results across different plants results emphasize that technological market and regulatory frictions may hinder the performance of energy policies

do women shy away from competition do men compete too much we examine whether men and women of the same ability differ in their selection into a competitive environment participants in a laboratory experiment solve a real task first under a noncompetitive piece rate and then a competitive tournament incentive scheme although there are no gender differences in performance men select the tournament twice as much as women when choosing their compensation scheme for the next performance while 73 percent of the men select the tournament only 35 percent of the women make this choice this gender gap in tournament entry is not explained by performance and factors such as risk and feedback aversion only playa negligible role instead the tournament entry gap is driven by men being more overconfident and by gender differences in preferences for performing in a competition the result is that women shy away from competition and men embrace it

foreign banks and foreign currency lending in emerging europe based on survey data from 193 banks in 20 countries we provide the first bank level analysis of the relationship between bank ownership bank funding and foreign currency fx lending across emerging europe our results contradict the widespread view that foreign banks have been driving fx lending to retail clients as a result of easier access to foreign wholesale funding our cross sectional analysis shows that foreign banks do lend more in fx to corporate clients but not to households moreover we find no evidence that wholesale funding had a strong causal effect on fx lending for either foreign or domestic banks panel estimations show that the foreign acquisition of a domestic bank does lead to faster growth in fx lending to households however this is driven by faster growth in household lending in general not by a shift towards fx lending

workplace productivity and bonus preferences why do men with low productivity prefer individual pay this paper examines the relationship between workers productivity and preferred bonus scheme the data are from a company where agents work in teams and receive a bonus that depends on individual and team performance standard agency theory predicts that workers with productivity below the team average prefer a team bonus while high productivity agents prefer an individual bonus risk aversion may temper the taste for individual pay this model predicts the observed relationship between productivity and bonus preferences very well there is however one pattern that it cannot explain many low performers especially men prefer individual bonuses

the impact of banking sector reform in a transition economy evidence from kyrgyzstan we examine the impact of financial sector reform on interest rate levels and spreads using kyrgyz bank level data from 1998 to 2005 we find that in addition to macroeconomic stabilization structural reforms to the banking sector significantly contributed to lower interest rates in particular our results suggest that foreign bank entry and regulatory efforts to increase average bank size were important in reducing deposit rates in contrast we find little evidence that banking sector reform or macroeconomic stabilization has impacted interest rate spreads

bank funding securitization and loan terms evidence from foreign currency lending we examine how bank funding structure and securitization activities affect the currency denomination of business loans we analyze a unique data set that includes information on the requested and granted loan currency for 99 490 loans granted to 57 464 firms by a bulgarian bank our findings document that foreign currency lending is at least partially driven by bank eagerness to match the currency structure of assets with that of liabilities our results also show that loan currency as well as loan amount and maturity are adjusted to make loans eligible for securitization

the use of linear logit models for dynamic input demand systems this paper demonstrates that a linear logit model with appropriate constraints can be used to specify a system of cost share equations that satisfy neoclassical economic conditions unlike many other flexible functional forms the logistic function is particularly well suited for incorporating dynamic adjustment mechanisms the empirical results suggest that the use of static models overstates short run own price elasticities and understates the corresponding long run price effects

euroization what factors drive its persistence household data evidence for croatia slovenia and slovakia the question asked in this article is why people continue to use foreign currencies even after their economies have stabilized survey data for croatia slovenia and slovakia are employed to provide an answer the results confirm the role of network effects and of remittances furthermore the extent of currency substitution is found to be positively associated with the level of income and education an important aspect of euroization seems to be age older people are more likely to hold foreign currencies in contrast neither expectations about inflation rates nor about exchange rates do seem to affect the degree of euroization in a systematic and predictable way trust in the banking system is found to affect the choice between foreign currency cash and foreign currency deposits overall the results support the view that the persistence in the use of foreign currencies is driven to a large extent by factors that are related to the past

fuel switching and climate and energy policies in the european power generation sector a generalized leontief model abstract the purpose of this paper is to analyze a the role and the nature of price induced switching behavior between fossil fuels i e coal oil and natural gas in the western european power sector as well as b the fuel choice impacts of a number of public policies implemented in this sector during the last 20 years the analysis is conducted within a generalized leontief cost function framework and employs pooled data across eight countries over the time period 1978 2004 we present short run own and cross price elasticities of fossil fuel demand and assess the impacts of a set of government policies implemented over this time period the empirical results show evidence of notable short run interfuel substitution between oil and gas and particularly in countries where fossil fuels are used extensively for both base and peak load purposes these findings support the notion that ex post fossil fuel substitution takes place in dual and multi fired plants by switching load between different single fuel fired plants as well as through the conversion of power plants to be able to burn alternate fuels the results also illustrate that different public policies i e removal of coal subsidies electricity market liberalization etc have had profound impacts on fossil fuel choices and have in particular favored power generation gas use at the expense of coal finally the paper makes use of the empirical results to simulate the fuel switching impacts of different carbon prices within the european emissions trading scheme eu ets

a pooled dynamic analysis of interfuel substitution in industrial energy demand by the g 7 countries a dynamic version of considine s 1990 linear logit model is used to obtain theoretically consistent estimates of long run price elasticities from pooled intercountry data on industrial energy consumption this model also provides a rare direct estimate of the important rate of dynamic adjustment revealing a median lag of ten years the long run demands for oil and coal are the most elastic and the strongest channels for interfuel substitution are between oil and natural gas with no significant evidence of complementarity between fuels

social mobility and the demand for redistribution the poum hypothesis this paper examines the often stated idea that the poor do not support high levels of redistribution because of the hope that they or their offspring may make it up the income ladder this prospect of upward mobility poum hypothesis is shown to be fully compatible with rational expectations and fundamentally linked to concavity in the mobility process a steady state majority could even be simultaneously poorer than average in terms of current income and richer than average in terms of expected future incomes a e rst empirical assessment suggests on the other hand that in recent u s data the poum effect is probably dominated by the demand for social insurance in the future everyone will be world famous for e fteen minutes andy warhol 1968

the economics of fuel choice at us electric utilities abstract this paper compares and contrasts results obtained from estimating fossil fuel cost shares in the generation of electricity in the usa from two models one national and one regional while the national model provides acceptable first order results correct signs and magnitudes of critical parameters it is the regional model that reveals the underlying economics of this fuel choice problem results which hold consistently across regions and across fuels are more plausible than those which are found to be special cases in each region of the country or for each fuel type

reason for reserve reserve requirements and credit this paper considers the impact of a regulatory policy action on bank credit and traces its incidence across banks i make use of a reserve requirement increase in lebanon that was considerably greater on foreign currency deposits than on domestic currency deposits all banks cut lending as they scrambled to adjust portfolios but the policy shock disproportionately affected banks with a greater reliance on dollar funding and with low buffers of dollar liquid assets exposed domestic owned banks also adjusted more slowly than similar foreign owned banks that obtained outside funding descriptive firm bank matching evidence reveals a disproportionate impact on small firms

foreign currency borrowing by small firms in emerging markets when domestic banks intermediate dollars this paper investigates what induces small firms in an emerging market economy to borrow dollar credit from domestic banks our data are from a unique survey of firms in lebanon the findings complement studies of large firms with foreign currency loans from foreign lenders exporters naturally hedged against currency risk are more likely to incur dollar debt firms also partly hedge themselves by passing currency risk to customers and suppliers less opaque firms with easily verifiable collateral and higher net worth are more likely to access dollar credit firms reliant on formal financing banks and supplier credit are more likely to contract dollar debt than firms reliant on informal financing family friends and moneylenders bank relationships however do not increase the dollar debt likelihood and finally profitable firms are less likely to have dollar debt information frictions and limited collateral therefore constrain dollar credit even when it is intermediated domestically

households foreign currency borrowing in central and eastern europe abstract foreign currency loans represent an important feature of recent financial developments in ceecs this might pose a serious challenge for macroeconomic stability against this background we study the determinants of foreign currency loans of households using data on the behavior of households in nine ceecs our results reveal that foreign currency loans are driven by households lack of trust in the stability of the local currency and in domestic financial institutions moreover special factors including remittances and expectations of euro adoption play an important role in selected regions the financial crisis reduced foreign currency borrowing but there is some indication this effect might be only temporary

the euroization of bank deposits in eastern europe in central eastern and southeastern europe a substantial share of bank deposits are denominated in foreign currency deposit euroization poses key challenges for monetary policy and financial sector supervision on the one hand it limits the effectiveness of monetary policy interventions on the other hand it increases financial sector fragility by exposing banks to currency risk or currency induced credit risk policymakers disagree on whether countries in the region should tackle deposit euroization with dedollarization policies or should rather strive to adopt the euro as their legal tender assessing the potential effectiveness of dedollarization policies requires a clear understanding of which households hold foreign currency deposits and why they do so on the basis of survey data covering 16 375 households in ten countries in 2011 and 2012 we provide a comprehensive household level analysis of deposit euroization in central eastern and southeastern europe we examine how households preferences for and holding of foreign currency deposits are related to individual expectations about monetary conditions and network effects we also examine to what extent monetary expectations and deposit euroization are the legacy of past financial crises or the outflow of current policies and institutions in the region our findings suggest that deposit euroization in central eastern and southeastern europe can be partly tackled by prudent monetary and economic decisions by today s policymakers the preferences of households for euro deposits are partly driven by their distrust in the stability of their domestic currency which in turn is related to their assessment of current policies and institutions however our findings also suggest that a stable monetary policy may not be sufficient to deal with the hysteresis of deposit euroization across the region first we confirm that the holding of foreign currency deposits has become a habit in the region second we find that deposit euroization is still strongly influenced by households experiences of financial crises in the 1990s our findings question the effectiveness of supply side interventions e g bank regulation or demand side interventions e g local currency capital market development in de euroizing household savings first we show that deposit euroization is largely demand driven second we show that households already have access to a broad range of savings products in local currency

cluster sample methods in applied econometrics inference methods that recognize the clustering of individual observations have been available for more than 25 years brent moulton 1990 caught the attention of economists when he demonstrated the serious biases that can result in estimating the effects of aggregate explanatory variables on individual specific response variables the source of the downward bias in the usual ordinary least squares ols standard errors is the presence of an unobserved state level effect in the error term more recently john pepper 2002 showed how accounting for multi level clustering can have dramatic effects on t statistics while adjusting for clustering is much more common than it was 10 years ago inference methods robust to cluster correlation are not used routinely across all relevant settings in this paper i provide an overview of applications of cluster sample methods both to cluster samples and to panel data sets

fossil fuel flexibility in west european power generation and the impact of system load factors this paper analyzes short run interfuel substitution in west european power generation and the impact of system load factors on fossil fuel choice the problems are studied within a restricted translog cost share model the paper concludes that interfuel substitution in existing power plants is substantial especially that between oil and gas this is consistent with the notion that short run fuel substitution takes place in dual or multi fired plants by switching load between different single fired plants and by some conversions of power plants to be able to burn alternate fuels the empirical investigation also indicates that the system load factor is a notable determinant of fossil fuel choices in west europe and the paper ends with an assessment of the fuel consequences of some load management schemes in the region

what drives credit dollarization in transition economies abstract this paper provides an in depth analysis of the use of foreign currencies in the lending activities of banks in transition economies the impact of bank and firm variables on credit dollarization is studied in an optimal portfolio allocation model and estimated using new aggregate data for 21 transition economies for the period 1990 2003 empirical results provide evidence that credit dollarization is the combined outcome of domestic deposit dollarization and banks desire for currency matched portfolios beyond regulatory requirements the effects of international financial factors and natural hedges are less robust across alternative specifications the paper further discusses the role of regulations in affecting the impact of these factors on credit dollarization and calls for more developed domestic forward foreign exchange markets
