a regional energy hub for achieving a low carbon energy transition abstract the transition to a low carbon energy economy will remain a cornerstone of national energy policies of countries committed to the climate change accord for decades to come we think that transmission investment is one key policy instrument amongst other to help with this transition we propose an enhanced role for investing in transmission capacity for inter regional trade to allow effective fuel switching among countries through a physically connected market we develop a conceptual framework of regional energy hubs and propose a cost minimization model in support of a transmission investment strategy that integrates i a key geopolitical parameter for countries that are geographically close in a region but under different political jurisdictions judged as stable and receptive to firm trading arrangements ii an economic parameter related to the fuel mix where the differences in a country s supply and demand characteristics are significant enough for allow mutual benefits to be realized through cost reduction iii an environmental parameter linked to a country s carbon intensity that could benefit from the resources of a neighboring jurisdiction with lower intensities and iv a financial parameter for each country within a region capable of attracting investment capital a connected regional energy hub offers large economic and environmental benefit for transition to a low carbon energy economy

the implications of brexit for the electricity sector in great britain trade offs between market integration and policy influence this paper examines the trade off between the economic gains to great britain gb from being integrated into the eu electricity market on the one hand and a loss of influence over policy and rule making on the other the aim is not to predict how this trade off will be resolved in practice but rather to lay out what is at stake on both sides of the equation since the late 2000s the electricity market in gb has become increasingly integrated with continental european markets through market coupling and increasing interconnection capacity with further integration expected up to the mid 2020s estimates of the economic benefits of this integration range up to the order of several 100 m to 1bn a year representing the economic cost of a reversal of such integration on the other hand maintaining and expanding electricity market integration would require the acceptance of electricity policies and regulations made in european institutions in which uk actors would have little if any voice an intermediate multilateral approach offering the possibility of retaining market integration with less cost in terms of influence is proposed

tourism demand forecasting models choice of appropriate variable to represent tourists cost of living abstract price is generally regarded as a major determinant of demand tourism has two price elements the cost of travel to the destination and the cost of living for tourists in the destination previous studies where econometric forecasting models have been developed for international tourism demand usually take the consumer price index in a country to be a proxy for the cost of tourism in that country owing to lack of appropriate data this article attempts to evaluate the performance of proxy variables compared with a specific tourists cost of living variable within the context of tourism demand forecasting models

electricity market integration decarbonisation and security of supply dynamic volatility connectedness in the irish and great britain markets abstract this study investigates the volatility connectedness between the irish and great britain electricity markets and how it is driven by changes in energy policy institutional structures and political ideologies we assess various aspects of this volatility connectedness including static unconditional vs dynamic conditional symmetric vs asymmetric characteristics between 2009 and 2018 we find that the volatility connectedness is time varying and it is significantly affected by important events policy reforms or market re designs such as brexit oil price slump an increasing share of renewables and fluctuations in the exchange rates our asymmetric analysis shows that magnitude of the good volatility connectedness is marginally larger than that of the bad volatility connectedness our result suggests that good volatility levels would be even higher once the irish market adopts the carbon price floor therefore supporting renewable generation by setting an appropriate price of carbon in interconnected wholesale electricity markets will improve market integration

british tourism demand elasticities in mediterranean countries we use the almost ideal demand system aids model developed by deaton and muellbauer 1980 to estimate tourism demand elasticities for a number of mediterranean countries cyprus greece italy malta portugal spain and turkey in relation to tourists originating from the united kingdom during the period 1963 to 2009 using the restrictions imposed by theory we find that the model is able to explain developments in market shares reasonably well despite the large and at times sudden changes in market shares over the sample period our share estimates indicate that while spain and portugal managed to keep a stable market share over time malta and especially italy lost market share to cyprus greece and turkey overall we observe that italy and spain have the lowest own price elasticities whereas greece portugal spain and turkey are expenditure inelastic holiday destinations we also improve over the traditional treatment of the aids model in the literature by studying the stability of the estimat

the economic consequences of brexit energy in this paper we raise a number of issues that are important for the uk to consider in the light of its decision to leave the european union eu the first of these is the nature of the eu single market in electricity and gas and the uk s role within this the second is the nature of uk energy policy in the light of brexit and the opportunities for changing this and third we consider some of the key issues to be addressed in a negotiating position with the eu

strategic eurasian natural gas market model for energy security and policy analysis formulation and application to south stream abstract the mathematical formulation of a strategic eurasian natural gas market model is presented the model represents horizontal oligopolistic relationships among producers bilateral market power between producer russia and transit ukraine countries detailed transport constraints and operation decisions over a 20 year time horizon to demonstrate the model s capabilities a financial and market analysis of the proposed south stream gas pipeline from russia via the black sea to south europe is summarized insights obtained include the following first expectations of high demand growth in europe and or transit risks do not justify the construction of the south stream pipeline because under all demand and ukraine transit interruption scenarios the net benefits to the south stream participants are negative the npv ranges from 1 9 billion bn to 7 4 bn second ukraine s perception of high transit market power vis a vis russia may trigger the construction of the otherwise unprofitable south stream project thus under ukraine s high transit market power scenario the npv of south stream ranges between 2 4 bn and 24 5 bn third we find that the south stream investment increases the efficiency of the european gas market under the following conditions i when gas demand in europe grows 2 per year up to 2030 ii when ukraine poses high transit market power or iii under a combination of severe transit risks through ukraine and low demand scenarios in europe it should be noted that the value of south stream to both its project sponsors and the market as a whole is much higher when ukraine exercises transit market power than under the high demand scenario therefore whether ukraine is likely to wield market power is crucial to the success of the south stream project because that is the only scenario in which the project yields both a positive expected npv to its sponsors and the highest value to the market as a whole

did rabuka s military coups have a permanent effect or a transitory effect on tourist expenditure in fiji evidence from vogelsang s structural break test abstract the central aim of this paper is to investigate whether the military coups instigated by major general sitiveni rabuka in 1987 had a permanent effect or a transitory effect on tourist expenditures in fiji to accomplish this aim we use the vogelsang econ theory 13 1997 818 test for one break in linear trending data the vogelsang test reveals 1988 as the year of the break and based on a suite of test statistics recommended by vogelsang we reject the unit root null leading to the conclusion that rabuka s coups had a transitory effect on tourist expenditure in fiji

a micro analysis of business travel demand this study tests two hypothesis 1 that tax deductibility and the dual benefit nature of goods on the business pleasure borderline increases the demand for business travel and 2 that this dual benefit decreases price elasticity the study uses expenditure microdata and contrasts the behaviour of business travellers and pleasure travellers both groups are assumed to have indentical tastes but the expenditure behaviour of business travellers is modified by the role of the business trip as a factor of production the linear expenditure system les allocation model is applied to expenditures on individual goods at a particular tourist destination business travellers are shown to have higher expenditures than pleasure travellers for food lodging and local transportation minimum quantities estimated by the les are also higher for business travellers uncompensated price elasticities of business travellers are significantly smaller than that of pleasure travellers for local transportation clothing a

investment options and bargaining power the eurasian supply chain for natural gas we use cooperative game theory to analyze how the architecture of the pipeline network determines the power structure in the supply chain for russian gas if the assessment is narrowly focused on the abilities to obstruct flows in the existing system the main transit countries belarus and ukraine appear to be strong if investment options are accounted for however russia achieves clear dominance we show that options to bypass one of the transit countries are of little strategic importance compared to russia s direct access to its customers through the baltic sea comparing the results of our calibrated model with empirical evidence obtained from transit and import agreements we find that the shapley value explains the power of major transit countries better than the core and the nucleolus

interdependent international relations and the expansion of ethanol production and consumption the brazilian perspective abstract the global production and consumption of ethanol are expected to increase the growing interdependence of markets and nations producers and consumers of biofuels has led actors to seek and devise mechanisms intended to develop the sector this paper aims to analyze the interdependent international relations between brazil and other ethanol biofuel producer and consumer countries to do so the paper explores the theory of complex interdependence and the game theory a quali quantitative study was conducted involving the application of two questionnaires to experts on biofuels and documentary analysis aided by qda miner software the results show that brazil shares highly interdependent relations with the united states an intermediate degree of interdependence with europe and a low degree of interdependence with china the dimensions of those interdependent relations can be ranked according to importance in the following order first the political then the economic technical and finally the social environmental dimensions a number of actions can be envisaged that could lead ethanol to achieve an increasingly strategic position in the diversification of the energy matrix in different countries technological efforts to improve production efficiency the creation of globally integrated policies designed to provide security and develop the production and consumption infrastructure the reduction of international tariffs on the product and the transformation of ethanol into a global commodity with a large number of countries buying and selling the product this paper faced the challenge of integrating approaches and concepts from two complex theoretical areas complex interdependence theory and game theory the research methodology and the insights gained from the ethanol case contribute to the literature on the applicability of these two theoretical approaches

greener more integrated and less volatile a quantile regression analysis of italian wholesale electricity prices abstract this paper provides estimates of quantile regression models of the relationship between italian day ahead electricity prices the supply of renewables and the inception of a new cable sapei linking sardinia with the italian peninsula in the 2006 2015 time window the results confirm the merit order effects detected in the existing literature both for photovoltaics and wind power more strongly in market conditions characterised by moderately low price levels and with some implied increase in volatility the new cable has apparently challenged the ability of power generating companies to extract value through price spikes has mitigated volatility and its effects have been complementary with those of renewables effects from photovoltaics are more sensitive to robustness checks differences across zonal markets are nonetheless detected

a preliminary assessment of the market coupling arrangement on the kontek cable this paper presents a preliminary assessment of the market coupling arrangement on the kontek kt cable between east denmark and germany and an assessment of the original auction mechanism kt the new spot price area was introduced in germany on october 5 2005 to facilitate a market coupling arrangement on the kt cable between east denmark and germany we would expect the kt price to correlate more with the european energy exchange eex price because arbitrage normally levelizes the price however spot prices in late 2005 were both high and volatile because congestion management practices in sweden transferred internal bottlenecks to the cable between sweden and east denmark since spot prices were equal in east denmark and the kt area for a substantial time it implies that some hours had no congestion on the kt cable market players valued the previous monthly auctions for transmission capacity more than the daily auctions compared to the daily auctions market players received smaller payoffs on average for the market coupling arrangement and the smallest payoffs for the monthly auctions

speculative trading of electricity contracts in interconnected locations abstract we derive an investor s optimal trading strategy of electricity contracts traded in two locations joined by an interconnector the investor employs a price model which includes the impact of her own trades the investor s trades have a permanent impact on prices because her trading activity affects the demand of contracts in both locations additionally the investor receives prices which are worse than the quoted prices as a result of the elasticity of liquidity provision of contracts furthermore the investor is ambiguity averse so she acknowledges that her model of prices may be misspecified and considers other models when devising her trading strategy we show that as the investor s degree of ambiguity aversion increases her trading activity decreases in both locations and thus her inventory exposure also decreases finally we show that there is a range of ambiguity aversion parameters where the sharpe ratio of the trading strategy increases when ambiguity aversion increases

interpreting concentration indices in the secondary market for natural gas transportation the implication of pipeline residual rights abstract in 1992 the u s federal energy regulatory commission created a secondary market for natural gas transportation whereby shippers holding firm transportation capacity on interstate natural gas pipelines can compete with the pipeline in the provision of transportation services however if a shipper does not use some of its contracted firm transportation capacity the pipeline can resell that capacity as interruptible transportation that is the pipeline has residual rights with respect to firm transportation capacity contracted for by shippers we demonstrate that these residual rights can have a significant effect on the competitiveness of the secondary market for natural gas transportation a consequence of these residual rights is that the secondary market for natural gas transportation may be considerably more competitive than indicated by measures of concentration like the widely used herfindahl hirschman index

social construction and physical nihilation of the keystone xl pipeline lessons from international relations theory abstract if a prime goal of energy policy is to achieve energy security why is there a controversy over the proposed keystone xl pipeline designed to deliver new supplies of oil from within north america this viewpoint seeks answers in the debate over the underlying purposes of energy policy how does one answers the question what do we want from energy policy perceptions of feasible answers and policy options change over time as witnessed in the 1970s analogous shifts in opinion are changing today s policy debates and widening the contradictions in policy purposes attention to the existence of these contradictions without illusions is necessary to meet the policy challenges of the future effectively

consumer behaviour theory and empirical evidence a survey this survey is designed to emphasize the relationship between empirical a nd theoretical considerations in the analysis of consumer behavior a lthough it focuses primarily on analysis at the individual or micro l evel it tries where possible to draw implications for the estimati on of aggregate relationships the importance of micro level analysis stems from the rapid expansion in available panel and survey data se ts this development has generated its own theoretical and empirical issues many of which are raised in this survey copyright 1988 by royal economic society

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

terrorism and attitudes towards minorities the effect of the theo van gogh murder on house prices in amsterdam abstract does fundamentalist islamic terrorism have an effect on the general attitudes towards muslim minorities we use the murder of theo van gogh as an event study to address this question specifically we use the hedonic market model and test for an effect on listed house prices in neighborhoods where more than 25 of the people belong to an ethnic minority from a muslim country type i relative to the other neighborhoods house prices in type i neighborhoods decreased in 10 months by about 3 with a widening gap over time our results are robust to several adjustments including using synthetic control groups finally we find evidence that segregation increased people belonging to the muslim minority were more likely to buy and less likely to sell a house in a type i neighborhood after the murder than before

consumer behaviour in greece an application of the almost ideal demand system this paper estimates the almost ideal demand system on greek data for the period 1960 1986 for seven commodity groups the results conform with earlier research findings that the homogeneity and symmetry restrictions of demand theory are broadly inconsistent with the data the imposition of the restrictions leads to substantial changes in the estimated elasticities in both the static and dynamic specifications the introduction of habit effects with lagged consumption supported statistically by the data led to plausible results leaving however the problem of rejection of homogeneity and symmetry intact

multimarket contact and collusive behavior traditional analyses of industrial behavior typically link the exercise of market power in an industry to internalfeatures such as demand conditions concentration and barriers to entry nevertheless some economists have remained concerned that external factors such as contact across markets may also play a significant role in determining the level of competitiveness in any particular industry in this article we examine the effect of multimarket contact on the degree of cooperation that firms can sustain in settings of repeated competition we isolate conditions under which multimarket contact facilitates collusion and show that these collusive gains are achieved through modes of behavior that have been identified in previous empirical studies of multimarketfirms

elecxit the cost of bilaterally uncoupling british eu electricity trade abstract the uk s withdrawal from the european union could mean that it leaves the eu s internal energy market for electricity elecxit this paper develops methods to study the longer term consequences of this electricity market disintegration especially the end of market coupling before european electricity markets were coupled different market closing times forced traders to commit to cross border trading volumes based on anticipated market prices interconnector capacity was often under used and power sometimes flowed from high to low price areas a model of these market frictions is developed empirically verified on 2009 data before french and british market coupling and applied to estimate the costs of market uncoupling in 2030 a less efficient market and the abandonment of some planned interconnectors would raise generation costs by 700 m a year 2 compared to remaining in the internal energy market this result is sensitive to how the british and french electricity systems develop over the coming decades economic losses are four times greater 2700 m a year if france retains substantial nuclear capacity due to its low marginal costs conversely losses are reduced by two thirds if uk weakens its decarbonisation ambitions as lower carbon prices subsidise british fossil fuel generation allowing electricity prices to converge with those in france a hard elecxit would make british prices rise and french prices fall in three of our four scenarios with the opposite movements in the fourth scenario

tests of restrictions in large demand systems abstract this paper compares some asymptotic tests of linear restrictions using exact results and monte carlo methods in systems which contain the same regressors in each equation it is found that under a variety of conditions a statistic suggested by deaton provides a better approximation to the true distribution in small sample situations than the wald likelihood ratio or lagrange multiplier tests

tourism and economic development a survey this article surveys the literature on tourism and economic development identifying the contribution that tourism can make to development including foreign currency income and employment and the costs that it entails single equation and system of equations models for estimating tourism demand are provided indicating developing countries potential to benefit from increasing expenditure on tourism but their susceptibility to deterioration in price competitiveness the main sectors of tourism supply transportation tour operators travel agents and accommodation are examined and the importance of cross country integration between firms is highlighted the article argues that many of the problems associated with the use of environmental resources for tourism stem from market failure and it considers methods for increasing sustainably the returns from them

a review of balancing costs in italy before and after res introduction abstract the massive introduction of res in electricity markets is recognized to have induced a merit order effect on wholesale prices while day ahead prices are likely to decline as res e production increases the effects on balancing market sessions are more ambiguous taking into account the northern italian zone characterized by a high solar pv and hydro penetration we provide empirical evidence that balancing quantities decreased while costs increased between two samples associated with low 2006 08 and high 2013 15 res levels we estimate balancing costs for different technologies and compare their dynamics across specific hours we find evidence of increasing balancing prices in particular market conditions that we interpret as a signal of strategic use of real time sessions by conventional producers prone to the merit order effect in the day ahead market we compare our results to those obtained in the german market where on the contrary balancing costs have decreased and postulate that the different market designs may explain these results our findings suggest that the italian policy makers should carefully monitor all trading sessions especially those close to real time to avoid the exercise of market power by few operators allowed to guarantee system security and additionally to promptly adopt a capacity market

shifting load through space the economics of spatial demand side management using distributed data centers demand side flexibility dsf in the electricity grid has become an active research area in recent years while temporal flexibility e g load shedding load shifting is already discussed intensively in literature spatial load migration still is an under researched type of dsf spatial load migration allows us to instantly migrate power consuming activities among different locations data centers dcs are power intensive and process information goods since information goods are easily transferable through communication networks power intensive processing of information goods is not necessarily tied to a specific location consequently geographically distributed dcs inherit in theory a considerable potential to globally migrate load we analyze the economics of spatially migrating load to provide balancing power using geographically distributed dcs we assure that neither of the participating electricity grids will be burdened by this mechanism by using historical data to evaluate our model we find reasonable economic incentives to migrate positive as well as negative balancing power in addition we find that current scenarios favor the migration of negative balancing power our research thus reveals realistic opportunities to virtually transfer balancing power between different market areas worldwide

a strategic model of european gas supply gasmod abstract this paper presents a model of the european natural gas supply gasmod which is structured as a two stage game of successive natural gas exports to europe upstream market and wholesale trade within europe downstream market and which explicitly includes infrastructure capacities we compare three possible market scenarios cournot competition in both markets perfect competition in both markets and perfect competition in the downstream with cournot competition in the upstream market eu liberalization we find that cournot competition in both markets is the most accurate representation of today s european natural gas market where suppliers at both stages generate a mark up at the expense of the final customer double marginalization our results yield a diversified supply portfolio with newly emerging lng exporters gaining market shares enforcing competition in the european downstream market would lead to lower prices and higher quantities by avoiding the welfare reducing effects of double marginalization binding infrastructure capacity restrictions strongly influence the results and we identify bottlenecks mainly for intra european trade relations whereas transport capacity in the upstream market is globally sufficient in the cournot scenario

an econometric study on estimation of trade shares using the almost ideal demand system in the world link the objectives of this paper are to analyse the import shares by country using the world trade matrix data for 25 countries regions of the world various methods for the analysis of import or export shares are used in the literature but none of the studies has made use of the approach of an almost ideal demand system aids deaton and muellbauer 1980 the results based on aids for import shares are plausible and when maximizing behaviour is not assumed estimation of import share equations by ordinary least squares is possible in the aids approach import shares turn out to be a function of real value of imports and export prices of major competitors homogeneity and symmetry restrictions can be tested and estimation with constraints can conducted using fiml full information maximum likelihood or equivalent methods the paper presents results for three important countries regions namely the usa japan and the eec as importing country regions and for major suppliers to each country region the impo

the institutionalisation of trust in the international climate regime abstract in the extensive literature on international environmental co operation trust is usually treated in terms of compliance and verification mechanisms on the assumption that there will always be incentives for parties to international agreements to cheat or to free ride indeed the establishment of adequate assurances that such behaviour will be detected and punished is frequently the sine qua non of agreement in the first place technical and legal compliance mechanisms have developed rapidly in environmental treaty making over the last two decades the climate regime is no exception and its provisions in this regard are briefly described and analysed however it will be argued that the development of trust amongst the parties goes well beyond formal compliance and depends upon the institutionalised relationships often amongst officials and technical experts that have grown up since the negotiations for a climate treaty commenced in the late 1980s

asymmetric causality between australian inbound and outbound tourism flows abstractwe employ the asymmetric version of the granger causality test to assess how australian inbound and outbound tourism flows across 49 markets countries are driven by the sign dependent variations in departure series or vice versa a multivariate generalized autoregressive conditional heteroscedasticity mgarch model is also estimated to study the time varying co volatility between inbound and outbound tourism growth rates we find that rising co volatility spillovers between inbound and outbound tourism are statistically significant for a number of markets the six markets that are most susceptible to global shocks are china hong kong papua new guinea singapore south africa and the united kingdom china is by far the largest of these markets and except for the united kingdom both arrivals and departures for each of these countries represent growing markets for australia we present recommendations for policymakers and destination management organizations dmos to assist in developing cust

a system of equations model of uk tourism demand in neighbouring countries this paper uses a system of equations model to examine tourism demand during periods of destination country transition and integration into the wider international community the almost ideal demand system model is applied to the uk demand for tourism in the neighbouring destinations france spain and portugal spain and portugal are interesting cases as during the period under consideration they experienced a process of transition from economies with characteristics typical of developing countries only entering the world bank s industrialized countries classification in the 1980s the paper examines the evolution of tourism demand during these countries transition from developing to developed status consideration of france as a neighbouring destination also allows the behaviour of tourism demand to be compared between relatively rich and poor countries the results show the extent to which the cross country behaviour of demand becomes more or less similar over time with respect to changes in ex

impact of terrorism on tourism in turkey empirical evidence from turkey this article aims at investigating the causal impact of terrorist attacks on the tourism industry in turkey based on the autoregressive distributed lag ardl bounds testing procedure for the period between 1986 and 2006 the ardl bounds test reveals that tourism is in a long run equilibrium level relationship with terrorism the evidence obtained from the long run and short run parameter estimates indicates the existence of a negative causal effect of terrorism on tourism

an assessment of the danish german cross border auctions abstract this paper presents an analysis of the auction prices at the cross border auction between west denmark and germany and between east denmark and germany the kontek cable monthly and annual transmission capacities appear to be more highly valued than daily transmission capacity on average the two cross border auctions show different trends the auctions between west denmark and germany exhibit a higher level of prices in the southbound direction and between east denmark and germany higher prices in the northbound direction we find a relatively strong correspondence in the pricing of products over different time frames daily monthly and annual auctions between west denmark and germany and a weak correspondence for the products between east denmark and germany in the daily auctions market players can decide whether to use their capacity after the clearing of the day ahead market while in the monthly and annual auctions they must decide whether to use their capacity prior to clearing if they choose not to use their capacity the use it or lose it principle applies the capacity is then subsequently released to the daily market since the daily cross border auctions are free of commitment they should be valued as options likewise in the monthly and annual auctions market players can choose not to nominate their capacity but as this must occur before the clearing of the day ahead market they will not know the directions of the power flows a priori if they nominate the capacity they must use it if the direction turns out to be wrong it is then possible to purchase capacity in the opposite direction in the daily auctions if market players can accurately predict the outcome of the spot markets day ahead the value of monthly and annual capacity should more closely reflect the value of an option thus one would expect the value of the monthly and annual capacity to be between the value of an option and an obligation although this suggests that the average price of daily capacity should be greater than monthly and annual capacity our data do not support this hypothesis the daily monthly and annual capacity auctions do not reflect the value of the underlying asset as specified by the appropriate valuation of the energy price differentials between west denmark and germany and east denmark and germany therefore market players are exposed to substantial variation in fees for congestion management on the cross border we study whether arbitrage improves over time and discern no obvious trend since the explicit auction procedure has not been cost efficient a better approach appears to be the new market coupling arrangement introduced on the kontek cable and on the border between west denmark and germany with the result that market players will pay a congestion management fee i e area price difference equal to the energy price differential resulting from the market coupling mechanism

terror fear and behaviour in the jerusalem housing market this paper tests the hypothesis that fear is a central factor in understanding human behaviour in the face of terror this claim is addressed in the context of behaviour in the jerusalem housing market over the terror stricken years in the city 1999 2004 using a unique data source and the tools of spatial data analysis the paper provides support for this hypothesis in three respects first patterns of terror in the city are shown to be increasingly deconcentrated over the period studied secondly the types of terror having the sharpest effect on residential property prices are those most associated with randomness thirdly the effect of terror is less on purchasing prices than on rental prices the former represent revealed long term behaviour less affected by fear and the latter short term behaviour more likely to be influenced by such disutility the paper concludes with some of the policy implications arising from these findings

testing equity market efficiency around terrorist attacks this article uses the nine major bombings since 1998 that have been attributed to al qaida to examine market efficiency including a test of rumours that investors traded with advance knowledge of attacks analysis of these related but individually unexpected events confirms markets are semi strong efficient it now takes well under a trading day to fully price in a completely unexpected attack on balance markets also proved strongly efficient with no conclusive evidence of insider trading

war terror and the tourism market in israel a supply and demand model of the israeli hotel industry is developed distinguishing between its domestic and foreign sectors model simulations are employed to examine the impacts of war and terrorist incidents on tourist activity and hotel revenues foreign demand for israeli hotel stays is highly price elastic and income inelastic and moderately sensitive to terrorist events domestic demand is price inelastic income elastic and terror insensitive in the wake of terror attacks hotels supply or minimum prices to israeli tourists shift downward reducing local market prices and encouraging more local tourism however the magnitude of these shifts is minor and the local market thus provides little buffer for dropoffs in foreign tourism by permitting excess capacity in such fashion hotels respond rationally to the price inelasticity of local demand

third degree price discrimination and consumer surplus this paper considers the effects of monopoly third degree price discrimination on aggregate consumer surplus discrimination is likely to reduce surplus relative to that obtained with a uniform price but surplus can rise under reasonable conditions if the ratio of the pass through coefficient to the price elasticity at the uniform price is higher in the market with the higher price elasticity then surplus is larger with discrimination for a large set of demand functions the relatively high pass through coefficient implies a large price reduction in this market with logit demand functions surplus is higher with discrimination if pass through is above 0 5

ideas institutions and interests in the politics of cross border electricity interconnection greenlink britain and ireland abstract increasing electricity interconnection is necessary for both closer market integration and facilitating more renewable generation across the european union however progress on the ground has been slow this paper adds to the literature on the politics of interconnection through a case study of a proposed link between ireland and great britain we analyse how the institutional setting for investment has evolved at eu and member state level and how the influence of stakeholders is mediated by the ability of actors to define their interests and by institutional points of entry using this framework we examine the greenwire greenlink project we find first that developments in the institutional context especially the adoption of a new cap and floor regime for merchant investment by the gb regulator have had both positive and negative impacts on the project second we find that regulators and governments in the two markets have found it hard to define their interests in the project and its net social benefit due to informational complexities and changes in information over time third the project has met with local public opposition that is strong but which has little leverage due to a lack of institutional entry points

implicit auctioning on the kontek cable third time lucky implicit auctioning in europe is about eliminating cross border trade inefficiencies by internalizing crossborder trade into the day ahead auction procedures of the power exchanges that are already organizing trade nationally on the kontek cable implicit auctioning has first been implemented with no coupling between the relevant power exchanges followed by a volume coupling implementation and finally a one way price coupling implementation that is still operational today the main contribution of this paper is to compare the theoretical properties of these three implementations and to analyze their performance empirically we find that the third implementation is significantly outperforming the previous two implementations but in this third implementation stakeholders partly abandoned the volume coupling approach they initially believed to be a viable alternative and institutionally easier to implement

from micro to macro via production networks amodern economy is an intricately linked web of specialized production units each relying on the flow of inputs from their suppliers to produce their own output which in turn is routed towards other downstream units in this essay i argue that the structure of this production network is key in determining whether and how microeconomic shocks affecting only a particular firm or technology along the chain propagate throughout the economy and shape aggregate outcomes therefore understanding the structure of this production network can better inform both academics on the origins of aggregate fluctuations and policy makers on how to prepare for and recover from adverse shocks that disrupt these production chains two recent events have brought to the forefront the importance of interconnections between firms and sectors in aggregate economic performance consider first the 2011 earthquake in japan while the triple tragedy of the earthquake the ensuing tsunami and the near nuclear meltdown at fukushima surely resulted in a significant destruction of human and physical capital its effects would have been largely restricted to the affected areas were it not for the disruption of national

an econometric study of tourism demand the aids model of us and european tourism in mediterranean countries the almost ideal demand system aids model was used to estimate tourism expenditure allocation by us and west european countries among a range of mediterranean destinations the approach has the advantage of an explicit basis in consumer expenditure theory and by modelling the changes in the budget shares of expenditure among destinations provides new information relative to that provided by the traditional single equation approach the estimated model was econometrically satisfactory although symmetry and homogeneity were rejected in line with the findings of past studies of consumer demand the expenditure elasticities demonstrated considerable differences in tourism demand preferences between origin countries and between traditional and newly developing destinations the own and cross price elasticities indicated the importance of effective prices in determining the allocation of expenditure among destinations
