longevity risk subjective survival expectations and individual saving behavior abstract we provide evidence of individuals awareness of longevity risk the uncertainty about future survival probabilities based on subjective survival expectations elicited in the survey of health ageing and retirement in europe share and matching data on longevity risk from the human mortality database we find a positive relationship between the forecast dispersion in subjective survival estimates and longevity risk which indicates that individuals are to some extent aware of longevity risk our analysis of savings behavior shows that the dispersion in survival estimates is primarily explained by individuals disagreeing on the survival probability and not by their true awareness of the underlying uncertainty individuals do not save more on average when faced with longevity risk although theory suggests they should

randomization devices and the elicitation of ambiguity averse preferences abstract in random incentive mechanisms agents choose from multiple problems and a randomization device selects a single problem to determine payment agents are assumed to act as if they faced each problem on its own while this approach is valid when agents are expected utility maximizers ambiguity averse agents may use the randomization device to hedge and thereby contaminate the data

the interdependence of european russian energy relations abstract the aim of this article is to explore this dynamic interdependent relationship between russia and europe in the field of energy based on the concept of interdependence and perspectives on the political aspects of trade relations we discuss how russia can exercise power based on its energy resources and how the eu can compensate for its lack of power in the energy game with other trade related capabilities in particular we explore the implications of the lack of a full fledged eu foreign energy policy towards russia with the somewhat counter intuitive conclusion that the eu countries on average not necessarily are better off with a common foreign energy policy

does lootable wealth breed disorder a political economy of extraction framework this article proposes a political economy of extraction framework that explains political order and state collapse as alternative outcomes in the face of lootable wealth different types of institutions of extraction can be built on lootable resources with divergent effects on political stability if rulers are able to forge institutions of extraction that give them control of revenues generated by lootable resources then these resources can contribute to political order by providing the income with which to govern conversely the breakdown or absence of such institutions increases the risk of civil war by making it easier for rebels to organize the framework is used to explain two puzzling cases that experienced sharply contrasting political trajectories in the face of lootable resources sierra leone and burma a focus on institutions of extraction provides a stronger understanding of the wide range of political outcomes from chaos to dictatorship to democracy in resource rich countries

stock market returns and annuitization abstract i investigate the strong negative relation between recent stock returns and the annuitization of retirement savings using a novel data set with over 100 000 actual payout decisions after controlling for several standard explanations e g wealth effects i present evidence supporting naive beliefs and extrapolation from past returns the effect of recent returns on annuitization dramatically increases with age confirming that the elderly rely most heavily on recent information my results provide insights into how beliefs are formed in old age and have implications for the design of public policies seeking to promote annuitization

imperfect information and the business cycle imperfect information has played a prominent role in modern business cycle theory this paper assesses its importance by estimating the new keynesian nk model under alternative informational assumptions one version focuses on confusion between temporary and persistent disturbances another on unobserved variation in the inflation target of the central bank a third on persistent mis perceptions of the state of the economy measurement error and a fourth assumes perfect information the standard nk dsge version imperfect information is found to contain considerable explanatory power for business fluctuations signal extraction seems to provide a conceptually satisfactory empirically plausible and quantitatively important business cycle mechanism

optimal annuitization uncertain survival probabilities and maxmin preferences we consider a life cycle model with bequest motives and assume that the individual does not know his her survival probability and has maxmin utility preferences we show that it is optimal not to annuitize but to purchase pure life insurance policies instead

an experimental test on retirement decisions i introduction the reform of social security systems is now one of the main issues on the economic policy agenda of most industrialized countries it is widely considered that unless serious changes take place the aging of the population implying a rise in the number of retirees relative to that of workers will threaten the viability of pay as you go public pension systems in the long run this threat is being reinforced by the progressive reduction in the retirement age of the working population the central reforms that are being proposed to neutralize these future financing problems are the raising of the contribution rate the decreasing of pension benefits or and the delay of the retirement age with reference to this latter reform as blondal and scarpetta 1998 state a direct way to encourage people to work longer would be to raise the pensionable age but delaying the retirement age may not be very popular according to recent surveys most workers claim that they are happy with the current retirement age see cremer and pestieau 2003 this may help to explain why reforms on the legal retirement age have currently become a very delicate matter for governments 1 on the other hand pension systems in virtually all organization for economic cooperation and development oecd countries in the mid 1990s made it financially unattractive to work after the age of 55 see gruber and wise 1997 or blondal and scarpetta 1998 indeed the general consensus in the theoretical literature related to social security and retirement decisions is that pension systems create enormous incentives to leave the labor force early 2 therefore increasing the retirement age as a tool to improve the financial problems of public pensions systems faces two sensitive problems the opposition of workers to a delay in the standard retirement age and the disincentives to continuous work being embedded in the pension system the large decline in labor force participation is attributed to the specific fact that to keep on working implies a reduction in the present value of total pension benefits the terms old age pension wealth and implicit tax on postponing retirement have been frequently used to illustrate these disincentives in the pension system the old age pension wealth is the discounted value of expected pension benefits minus the discounted cost of obtaining such benefits after the earliest age at which pensions can be accessed working for an extra year may imply changes in this pension wealth by foregoing 1 yr of pensions paying contributions for an additional year and maybe increasing the pension benefits per year therefore if the costs of postponing retirement are higher than the gains then it is considered that the pension system is implicitly taxing to prolong the working period that is the drop in pension wealth acts as an implicit tax on income from continued work and as such is a clear incentive to retire early actually reforms aiming to increase the effective retirement age to improve the financial problems of public pensions systems have mainly focused on the reduction of this implicit tax on prolonging the working period it is also considered that when the increase in pension benefits is exactly offset by the higher cost in terms of contributions and forgone pensions the pension system is not distorting the retirement decision that is the pension systems that are marginally actuarially fair will not distort individual decisions concerning retirement age and consequently they are defined as neutral systems for this reason the main economic policy measures move in the direction of strengthening the link between lifetime contributions and pension benefits 3 indeed this reform is one of the policy conclusions of maintaining prosperity in an ageing society oecd 2000 the most appropriate reform would be to allow people to retire at the age of their own choice and to adjust pension level so that the pension system is neutral on average

how deep is the annuity market participation puzzle using microeconomic data for the united kingdom we analyze the empirical determinants of voluntary annuity market demand we find that annuity market participation increases with financial wealth life expectancy and education and decreases with other pension income and a possible bequest motive for surviving spouses we then show that these empirically motivated determinants of annuity market participation have the same quantitatively important effects in a life cycle model of annuity and life insurance demand saving and portfolio choice moreover reasonable preference parameters predict annuity demand levels comparable to the data for stockholders a strong bequest motive can simultaneously generate balanced portfolios and low annuity demand

withering government spending multipliers the empirical literature has documented a weakening of the consumption and output responses to an increase in government spending during the last thirty years we show that a new keynesian model in which real government spending is observed with measurement errors can account for the reduction in the size of government spending multipliers the model implies consistent with empirical evidence presented by ilzeki et al 2009 that the evolution of monetary policy and greater globalization increasing international trade and decreasing capital controls are key factors in this development

contra coercion russian tax reform exogenous shocks and negotiated institutional change the view of institutions as coercion rather than as contracts dominates the comparative politics literature on both institutional creation and the politics of economic reform the emergence of a collectively optimal tax code in russia demonstrates the limitations of this emphasis on coercion this new tax code was not imposed by a strong central leader mandated by international institutions or the result of state capture by powerful economic interest groups rather it is the product of a mutually beneficial exchange between the russian government and the russian oil companies russia s ability to negotiate an effective tax regime also suggests the conditions under which and the microcausal mechanism whereby exogenous shocks promote institutional change and economic reform owing to their mutual vulnerability and interdependence the august 1998 financial crisis generated widely shared perceptions among these actors that the payoffs of cooperation had changed yet the economic reform institution that resulted required a series of incremental strategic moves that established common knowledge

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

monetary misperceptions output and inflation dynamics we revisit the contribution of misperceived money to business cycles and in particular to the inertial dynamics of inflation following a monetary policy shock we establish three things first the difference between preliminary and revised money data captures monetary misperceptions well second misperceived money is quantitatively substantial and also matters significantly for economic activity and third imperfect information about monetary aggregates can help the standard nk model exhibit inertial inflation dynamics

do central banks respond to exchange rate movements a structural investigation abstract we estimate a small scale structural general equilibrium model of a small open economy using bayesian methods our main focus is the conduct of monetary policy in australia canada new zealand and the uk we consider generic taylor type rules where the monetary authority reacts in response to output inflation and exchange rate movements we perform posterior odds tests to investigate the hypothesis whether central banks do target exchange rates the main result of this paper is that the central banks of australia and new zealand do not whereas the bank of canada and the bank of england do include the nominal exchange rate in its policy rule this result is robust for various specification of the policy rule we also find that terms of trade movements do not contribute significantly to domestic business cycles

monetary policy in open economies abstract the recent literature on monetary policy in open economies has produced a strong presumption in favor of activistic policy and flexible exchange rates we argue that this result may owe much to the combination of two commonly made assumptions that nominal goods prices are rigid and that the monetary authorities have a lot of information about the economy when the source of nominal rigidity is found in wages and monetary policy is conducted according to less information demanding rules such as a standard interest rate rule policies that stabilize the money supply or the nominal exchange rate may perform better

consumption government spending and the real exchange rate using panel structural var analysis and quarterly data from four industrialized countries we document that an increase in government purchases raises output and private consumption deteriorates the trade balance and depreciates the real exchange rate this pattern of comovement poses a puzzle for both neoclassical and keynesian models an explanation based on the deep habit mechanism is proposed an estimated two country model with deep habits is shown to replicate well the observed responses of output consumption and the trade balance and the initial response of the real exchange rate to an estimated government spending shock

why don t people insure late life consumption a framing explanation of the under annuitization puzzle rational models of risk averse consumers have difficulty explaining limited annuity demand we posit that consumers evaluate annuity products using a narrow investment frame that focuses on risk and return rather than a consumption frame that considers the consequences for lifelong consumption under an investment frame annuities are quite unattractive exhibiting high risk without high returns survey evidence supports this hypothesis whereas 72 percent of respondents prefer a life annuity over a savings account when the choice is framed in terms of consumption only 21 percent of respondents prefer it when the choice is framed in terms of investment features

an experimental test of the under annuitization puzzle with smooth ambiguity and charitable giving abstract in a life cycle model with a bequest motive we study the impact of smooth ambiguity aversion to uncertain survival probabilities on the optimal demand for annuities we implement a theory driven laboratory experiment first a subject s ambiguity attitude is elicited in a simple experimental setting able to make the smooth ambiguity model operational then in a two period annuity bequest decision problem the subject s bequest in the second period is presented as a donation to a previously chosen charity contingent to the subject being active after the first period in line with the theoretical predictions we find that ambiguity averse resp loving subjects invest less resp more in annuities than ambiguity neutral ones furthermore subjects contingent donation to the chosen charity increases in their investment in annuities only for sufficiently high levels of warm glow altruism

are preliminary announcements of the money stock rational forecasts abstract we develop a theoretical framework of analyzing preliminary announcements of economic data and then apply this framework to the money stock we find that preliminary announcements of the money stock are best characterized as measured with classical errors in variables that is the revision is not correlated with the true value of the series the revision is however forecastable using information available at the time of the preliminary announcement our ability to forecast the revision implies that preliminary announcements are not rational estimates of the true money stock

frames of mind in intertemporal choice recent research has demonstrated that choices between gambles are systematically influenced by the way they are expressed kahneman and tversky s prospect theory kahneman d a tversky 1979 prospect theory an analysis of decision under risk econometrica472 363 391 explains many of these framing effects as shifts in the point of reference from which prospects are evaluated this paper demonstrates the applicability of the reference point concept to intertemporal choice three experiments demonstrate that when people choose between immediate and delayed consumption the reference point used to evaluate alternatives can significantly influence choice the first study elicited relative preference for immediate and delayed consumption using three methods each of which differently framed choices between alternatives offering identical end state consumption the conventional discounted utility model predicts that the three methods of elicitation should yield similar estimates of time preference but preferences were found to differ in accordance with a reference point model the second and third studies extend and replicate the results from the first the third using real rather than hypothetical choices

a framework to evaluate security of supply in the electricity sector security of electricity supply soes has become a major concern for regulators and policymakers over the last decade however most work focusses either more generally on energy security or on a single fuel we develop a comprehensive but flexible framework to assess the soes for a single jurisdiction taking into the account the specificities of electricity this framework has two aims i provide a snapshot of the situation to understand current weaknesses and determine what actions are required ii capture the evolution over time to evaluate progress and identify potential problems before they materialise the framework based on an extensive literature review consists of twelve dimensions that are critical for soes we develop metrics that capture the state and evolution of each dimension this framework is intended to be a management information tool for all stakeholders aimed at organising data and structuring its analysis to enable monitoring the evolution of the soes while also functioning as an early warning system by flagging potential future problems

indicator variables for optimal policy the optimal weights on indicators in models with partial information about the state of the economy and forward looking variables are derived and interpreted both for equilibria under discretion and under commitment an example of optimal monetary policy with a partially observable potential output and a forward looking indicator is examined the optimal response to the optimal estimate of potential output displays certainty equivalence whereas the optimal response to the imperfect observation of output depends on the noise in this observation

an experiment on risk taking and evaluation periods does the period over which individuals evaluate outcomes influence their investment in risky assets results from this study show that the more frequently returns are evaluated the more risk averse investors will be the results are in line with the behavioral hypothesis of myopic loss aversion which assumes that people are myopic in evaluating outcomes over time and are more sensitive to losses than to gains the results have relevance for the equity premium puzzle and also for the marketing strategies of fund managers

prelude to the resource curse explaining oil and gas development strategies in the soviet successor states and beyond the literature on resource rich states leaves a key and prior question unexplored why and how do states choose to develop their natural resources the authors address this gap by explaining the di

optimal annuitization with stochastic mortality and correlated medical costs the conventional wisdom since yaari 1965 is that households without a bequest motive should fully annuitize their investments numerous frictions do not break this sharp result we modify the yaari framework by allowing a household s mortality risk itself to be stochastic due to health shocks a lifetime annuity still helps to hedge longevity risk but the annuity s remaining present value is correlated with medical costs such as those for nursing home care thereby reducing annuity demand even without ad hoc liquidity constraints we find that most households should not hold a positive level of annuities and many should hold negative amounts jel d14 d82 g23 i12 j14 j26

endogenous oil rents oil rents may at times fall like manna from heaven into the fiscal coffers of the state yet politicians also make decisions that can increase or decrease the extent to which oil rents accrue to the central government though counterintuitive various evidence suggests that politicians sometimes do not seek to maximize the state s claim on rents in this article the author substantiates this observation with evidence from venezuela and then develops a formal model of the relationship between electoral competition and rent choice the author argues that the model can explain why politicians allowed the central government s share of rents to decline in venezuela beginning in the 1990s even though a decline in rents plausibly contributed to the destabilization of venezuelan democracy the argument illuminates patterns of rent capture in other cases whereas the model may be useful in many settings in which the gains from economic investment are realized over several electoral terms

behavioral obstacles in the annuity market as baby boomers enter retirement they will look to the investment industry for ways to generate income from accumulated savings why most retirees do not purchase longevity insurance in the form of lifetime annuities is a long standing puzzle mental accounting and loss aversion can explain the unpopularity of annuities by framing them as risky gambles where potential losses loom larger than potential gains moreover behavioral anomalies can explain the prevalence of period certain annuities which guarantee a minimum number of payouts finally investors may prefer longevity annuities purchased today to begin payouts in the future to immediate annuities because investors overweight the small probability of living long enough to receive large future payouts

energy security under de carbonization scenarios an assessment framework and evaluation under different technology and policy choices abstract how would a low carbon energy transformation affect energy security this paper proposes a framework to evaluate energy security under long term energy scenarios generated by integrated assessment models energy security is defined as low vulnerability of vital energy systems delineated along geographic and sectoral boundaries the proposed framework considers vulnerability as a combination of risks associated with inter regional energy trade and resilience reflected in energy intensity and diversity of energy sources and technologies we apply this framework to 43 scenarios generated by the message model as part of the global energy assessment including one baseline scenario and 42 low carbon scenarios where the global mean temperature increase is limited to 2 c over the pre industrial level by and large low carbon scenarios are associated with lower energy trade and higher diversity of energy options especially in the transport sector a few risks do emerge under low carbon scenarios in the latter half of the century they include potentially high trade in natural gas and hydrogen and low diversity of electricity sources trade is typically lower in scenarios which emphasize demand side policies as well as non tradable energy sources nuclear and renewables while diversity is higher in scenarios which limit the penetration of intermittent renewables

does issue linkage work evidence from european alliance negotiations 1860 to 1945 though scholars widely claim that issue linkage the simultaneous negotiation of multiple issues for joint settlement can help states conclude international agreements there exist some notable skeptics resolving this debate requires empirical evidence however beyond a few case studies there exists no direct and systematic evidence that issue linkages actually increase the probability of agreement i address this lack of direct and systematic evidence by combing original data on failed alliance negotiations with data from the alliance treaty obligations and provisions atop database using matching techniques i find that for alliance negotiations between 1860 to 1945 offers of trade linkage did substantially increase the probability of agreement besides confirming issue linkage s ability to help clinch an agreement this article s research design and evidence have far reaching implications for the study of negotiations and alliances the research design illustrates the value of considering the dogs that didn t bark as it identifies both successful and failed negotiations the article s evidence explains the high rate of alliance compliance identified by previous scholars and highlights a need to rethink the alliance formation process

who chooses annuities an experimental investigation of the role of gender framing and defaults research suggests that women are more risk averse and less financially literate than men as evidenced by their choice of less risky asset investments we contribute to the literature by focusing on the role of gender in an increasingly important financial decision facing individuals at retirement the choice between purchasing an annuity in this case a fixed immediate lifetime annuity or investing their savings on their own by using a controlled experiment we eliminate the role of adverse selection and unfair annu ity pricing and are able to focus specifically on gender we also explore the role of defaults and framing and whether women react differently to these features we find that women are more likely to choose the annuity and this is only partly explained by differences in risk aversion and financial literacy furthermore biases in a five minute presentation of information signifi cantly affect choices in ways that differ across men and women

when are sanctions effective a bargaining and enforcement framework although a considerable literature identifies the conditions under which sanctions are more likely to be successful few studies examine the question of when sanctioning states or senders are willing to enforce their sanctions laws against their firms using a game theoretic model we argue that imposing sanctions creates a strategic dilemma for senders we demonstrate that senders often have disincentives to enforce their sanctions policies given that the restriction on economic transactions with targeted states may undermine their firms competitiveness the model indicates that sanctions are more likely to succeed when the sender s firm retains a moderate share of the target s market relative to its foreign competitors however the model also demonstrates that sanctions are likely to be imposed only when the conditions do not favor their success the empirical implications of the model are tested using the threat and imposition of economic sanctions ties data set

annuities and individual welfare advancing annuity demand theory we present suffcient conditions for the optimality of full annuitization under market completeness that are substantially less restrictive than those used by yaari 1965 we examine demand with market incompleteness finding that positive annuitization remains optimal widely but complete annuitization does not how uninsured medical expenses affect demand for illiquid annuities depends critically on the timing of the risk a new set of calculations with optimal consumption trajectories very different from available annuity income streams still shows a preference for considerable annuitization suggesting that limited annuity purchases are plausibly due to psychological or behavioral biases

the hidden hand of economic coercion why do policymakers consistently employ economic sanctions even though scholars consider them an ineffective tool of statecraft game theoretic models of economic coercion suggest the success rate may be understated because of selection effects when the targeted country prefers conceding to incurring the cost of sanctions it has an incentive to acquiesce before the imposition of sanctions the bulk of successful coercion episodes should therefore end with sanctions threatened but not imposed this contradicts the recent literature on sanctions which assumes that sanctions rarely if ever work at generating significant concessions from the targeted country and are imposed for domestic or symbolic political reasons if the game theoretic argument is correct the crucial cases to study are those in which coercion is threatened but not implemented a statistical analysis of data on sanctions in pursuit of economic or regulatory goals strongly supports the gametheoretic argument these results suggest that the significance of economic coercion has been undervalued in the study of statecraft and international relations more generally

economic interdependence bargaining power and political influence bargaining theory is used to evaluate the proposition that asymmetrical economic interdependence among states is a source of political power it is shown that asymmetrical economic interdependence does not imply that less dependent actors will be able to exercise political influence over more dependent ones the use of economic interdependence for political influence requires instead that the exchange of economic resources for political concessions make both parties to a relationship better off than they would be if they bargained over the distribution of the gains from the economic relationship alone whether this is true is independent of the degree of asymmetry in the economic relationship or its direction an explanation is given for the fact that other scholars have reached different conclusions and the implications of these results for our understanding of a variety of types of relations among governments are derived

an experimental test of warm glow giving abstract this paper reports the results of an experimental test of the warm glow hypothesis a participant is presented with the opportunity to contribute from her own endowment to a charity of choice the experiment is designed so that a pure altruist has no incentive to donate the amount the designated charity will receive is preset any contribution by the participant crowds out dollar for dollar giving by the proctor we find that participants on average donated 20 of their endowments and that approximately 57 of the participants made a donation

portfolio choice in retirement health risk and the demand for annuities housing and risky assets in a life cycle model a retiree faces stochastic health depreciation and chooses consumption health expenditure and the allocation of wealth between bonds stocks and housing the model explains key facts about asset allocation and health expenditure across health status and age the portfolio share in stocks is low overall and is positively related to health especially for younger retirees the portfolio share in housing is negatively related to health for younger retirees and falls significantly in age finally out of pocket health expenditure as a share of income is negatively related to health and rises in age

will the european commission s policy hinder gas supplies to central and eastern european countries opal case decision abstract natural gas has become one of the most important sources of energy the liberalization of the gas sector in the last decades brought a dynamic development of the energy infrastructure in the eu thus it must be underlined that the liquidity of the gas market is dependent on the outside supplies the study examines the european commission s policy taking into consideration specifically its decision on the exemption of opal gas pipeline from eu rules the main question is what would be the long term effect of such policy in the authors opinion there are several serious doubts whether the commission has made an appropriate decision the major one concentrate on the impact of the decision which according to the commission refers only to germany and czechia gas market nevertheless an analysis of gas flow based on the entsog leads to a conclusions that decision could have a substantial influence on slovakia and poland if so under the eu provisions the investment can not be excluded form the eu rules therefore the authors will analyze step by step the commission decision and present its possible future impact on the internal energy market

do economic sanctions destabilize country leaders do economic sanctions destabilize the governments they target a form of foreign pressure sanctions are typically meant to alter the policies of other countries there is much pessimism on whether they ever work this article shows that economic pressure works in at least one respect it destabilizes the leaders it targets i present a theoretical argument that explains why destabilization is a necessary condition for successful coercion i find evidence that pressure destabilizes in a large panel of cross country time series data the destabilization finding indicates that sanctions may be more effective at altering policies than we think i conclude by noting that greater optimism regarding the effectiveness of sanctions should be balanced by a careful consideration of the policy s real and sizeable costs for those caught in the middle

preference reversals for ambiguity aversion this paper finds preference reversals in measurements of ambiguity aversion even if psychological and informational circumstances are kept constant the reversals are of a fundamentally different nature than the reversals found before because they cannot be explained by context dependent weightings of attributes we offer an explanation based on sugden s random reference theory with different elicitation methods generating different random reference points then measurements of ambiguity aversion that use willingness to pay are confounded by loss aversion and hence overestimate ambiguity aversion this paper was accepted by teck ho decision analysis

demand for annuities price sensitivity risk perceptions and knowledge abstract the demand for voluntary individual lifetime annuities is low as merely 10 of soon to be retired canadians care to buy such contracts to assess the reasons why we design a stated preference experiment in which we vary characteristics of annuity contracts to estimate individuals sensitivity to an annuity s money s worth that is the value to cost ratio using different measures of longevity risk and survival expectations we investigate how knowledge of annuity products and mortality risk misperceptions affect the take up and the sensitivity of the demand for annuities we find that annuities are objectively actuarially neutral in general meaning that annuity premiums are equal to their expected payment and can appear to offer great value for the money given an individual s subjective mortality risk we also find that demand is somewhat price inelastic so that lowering the price of annuities could increase demand by at most 2 percentage points for a base of 10 lack of knowledge of annuities explains another 0 8 percentage points we find limited additional interest for deferred annuities compared to immediate annuities although respondents are less sensitive to deferred annuity prices

the energy union and security of gas supply this paper discusses and contrasts the proposals for an energy union in the european union and its impact on security of gas supply based on an examination of historical east west gas trade and by revisiting energy security concepts the paper analyzes how problems with dependency on energy imports can be reduced the paper discusses how the positions of central and eastern european countries ceec where security challenges are especially evident and the positions of countries in western europe where they are less acute interact and conflicts in making a common energy security policy as part of the energy union the paper argues that the mainly confederative structure of the eu and diverging national situations make it difficult to unify positions into an effective common energy policy however with the ceec in the eu the eu is also changing and an increased focus on energy security may be accepted extended interconnectedness within and to the ceec appears to be the central issue that would mitigate albeit not solve contemporary security of gas supply problems as it would also bring the internal energy market closer to reality it could in addition help the energy union to become a unifying project merging the interests in the east and the west despite their different security of gas supply concerns with russian gas

the personal discount rate evidence from military downsizing programs the military drawdown program of the early 1990s provides an opportunity to obtain estimates of personal discount rates based on large numbers of people making real choices involving large sums the program offered over 65 000 separatees the choice between an annuity and a lump sum payment despite break even discount rates exceeding 17 percent most of the separatees selected the lump sum saving taxpayers 1 7 billion in separation costs estimates of discount rates range from 0 to over 30 percent and vary with education age race sex number of dependents ability test score and the size of payment
