A climate stress test on the financial vulnerability of Italian households and firms

This study presents a novel methodological framework for assessing the exposure of the Italian financial system to climate policy risks, using a micro-founded approach. By combining survey and administrative data with energy accounts and energy prices, we estimate the energy demand elasticity of Italian households and firms at the micro-level and we use this information to simulate the effects of four one-off carbon taxes (corresponding to €50, €100, €200 and €800 per ton of CO₂) on their income and profits. To compute if (and how) carbon taxes might affect the share of financially vulnerable agents and the debt at risk, these estimates are employed as an input for the microsimulation models used to monitor financial stability at the Bank of Italy. According to our results, a level of carbon taxation within the range of €50?200 per ton does not have a sizeable effect on the share of financially vulnerable agents. The micro approach allows us to take into account the heterogeneous transmission channels of climate risks and indicates that the financial risks stemming from climate shocks are limited overall and specific to individual households and industries.     

A portfolio of risk measures

A comprehensive set of sixteen measures of willingness to take risks has been developed. This set includes measures from three categories: measures from standardized risky situations having an underlying theory of risk, measures inferred from revealed choices in financial decisions, and measures derived from attitudes. A study of over 500 top-level business executives shows significant relationships within categories, but relatively little relationship across categories. Context differences, especially personal versus business situations and opportunities versus threats, underlie the responses.     

A model of the Canadian global exchange rate: A test of the 1970s

This comment points out some methodological weaknesses in the Canadian global exchange rate model and the associated efficiency tests of Marwah and Bodkin. The model is found to be inadequate for policy analysis.     

A model of the Canadian global exchange rate: A test of the 1970s

A review of the literature indicates that no single exchange rate model has been able to track successfully the movements of the Canadian dollar for both the 1970–1976 period and the period thereafter. The purchasing power parity model, irrespective of whether based on relative wholesale prices, unit labor costs, GNP deflators, or export prices performs very poorly; the monetarist models collapse because of their strict adherence to the purchasing power parity and interest rate parity assumptions; the portfolio demand models require a significant adjustment for the post-1976 period. This paper presents a medium-term eclectic model of the global exchange rate of the Canadian dollar and examines a spectrum of broad issues that reflect on the efficiency of the foreign exchange market of Canada. These issues are basically related to the interest parity assumption, the role of speculation, and the test of rational expectations. The global exchange rate is defined as the value of the Canadian dollar measured in terms of a unit of basket of currencies comprising currencies of France, West Germany, Japan, the U.K., and the USA. The model belongs to the same genre of balance of payments structural models that explain the exchange rates by balancing demand and supply of foreign currencies. The model simultaneously explains both spot and forward rates, and it has been estimated and tested by using the quarterly data for 1971–1981.     

A simple test on the convergence of social security transfer in OECD countries

The growing trend toward globalization not only has aggravated international competition but also has increased interdependence among countries, inducing the need for harmonization and convergence of socioeconomic policies across countries. This paper examines whether the convergence phenomenon holds for social security transfers as a percentage of GDP in OECD countries, applying the traditional methodology of σ- and β-convergence.     

On changes in the age composition of the population and policy options for population planning

This analysis, based on 1978 data from official household registers, suggests that the 1983-2000 period will be critical for China's efforts to control population growth. If declines in the fertility rate are maintained, the possibility of stabilizing China's population at 800-900 million in the next century is feasible. If the population is to be kept under 1.2 billion by the year 2000, the general fertility rate must be lowered to 1.8 in 1985 and must decline 0.1 each 5 years thereafter until it reaches 1.5 in the year 2000. Once population growth is brought under control, it will be necessary to address consequent increases in the median age of the population. Those over 65 years of age will comprise 7.1-7.8% of the population in the year 2000, depending on whether fertility rates are low or high. The medium projection includes a population of 1.211 billion in the year 2000, approaching the peak value but allowing the fertility rate to rise slowly to guard against excessive aging of the population. The proportion of those over 65 years of age reaches a peak value of 20.2% in the year 2040. Overall, these projections suggest a "golden age" continuing until about 2020 in which the proportion of those both over 65 years and under 15 years will be rather low. The dependency ratio should begin to climb after 2020, reaching a peak in 2040 and stabilizing by 2070 at a level slightly higher than that existing today in developed countries. Since a rational age composition and a suitable decrease in the proportion of dependents are essential for economic growth, future analyses should focus on the quality of the population and not just population size. As long as birth rates continue to fall, the proportion of the dependent population will also fall and have a beneficial effect on China's economic development.     

A test of generalized expected utility theory

In two experiments we test Machina's Hypothesis II (fanning-out). In each experiment we analyze patterns of responses to hypothetical lottery choice questions within a Marschak-Machina triangle. One set of questions involves lotteries on the border of the triangle, an the other set of questions involves lotteries in the interior of the triangle (off the border). Our results show that a large proportion of the observed patterns in the on-border treatment support Hypothesis II, with a considerable amount of fanning-out behavior observed. The patterns observed in the off-border treatment are significantly different from those in the on-border treatment. Hypothesis II performs well in the off-border treatment because expected utility theory itself, which satisfies the restrictions of Hypothesis II, performs well.This is an expanded version of a paper originally prepared for presentation at the Fifth International Conference on the Foundation and Applications of Utility, Risk, and Decision Theories, held June 9–13, 1990 at Duke University, Durham, NC. We acknowledge helpful comments made by participants at that conference, especially those of Mark Machina.     

Stochastic trends in the long-run behavior of velocity: A new test of the institutional hypothesis

The institutional approach to the long-run behavior of velocity has been implemented through testing whether proxy variables for the process of monetization, the spread of commercial banking, the level of financial sophistication, and economic stability are related to movements in velocity. In this paper I argue that a valid test of this type requires that a distinction is made between trends and temporary fluctuations in velocity and the institutional proxies. When this distinction is taken into account, it appears that the long-run behavior of velocity is less easily explained by the institutional variables than previous tests suggested.     

Risk and vulnerability in social assistance receipt of young adults in Finland

Social background may affect not only individuals’ wellbeing, but also their ability to manage the typical and problematic transitions occurring during young adulthood. Hence, this article has used Finnish population register data to analyse how social background and critical life‐course factors predict the number of months of social assistance received annually among young adults aged 19–29. Special interest was given to asking whether those with a disadvantaged social background are more vulnerable to the effects of critical life‐course factors. The results showed that social background and critical life‐course factors have independent effects on social assistance receipt. Additionally, this study shows that the effects and the incidence of critical life‐course factors can be affected by social background.     

A test of the gambler's fallacy: Evidence from pari-mutuel games

The “gambler's fallacy” is the belief that the probability of an event is decreased when the event has occurred recently, even though the probability is objectively known to be independent across trials. Clotfelter and Cook (1991, 1993) find evidence of the gambler's fallacy in analysis of data from the Maryland lottery's“Pick 3” numbers game. In the Maryland lottery, the payout to all numbers is equal at $250 on a winning fifty-cent bet, so the gambler's fallacy betting strategy costs bettors nothing. This article looks at the importance of the gambler's fallacy in the New Jersey lottery's three-digit numbers game, a pari-mutuel game where a lower amount of total wagering on a number increases the payout to that number. Results indicate that the gambler's fallacy exists among bettors in New Jersey, although to a lesser extent than among those in Maryland.     

A test of the characteristic function and the Harsanyi function in N-person normal form sidepayment games

This paper reports the results of a laboratory experiment investigating sidepayment games represented in normal form. Attempts to predict payoff allocations via the application of solution concepts (such as the Shapley value or the nucleolus) encounter a problem in games of this form, because the game must first be transformed into some other form. Commonly, this other form is a set function defined over coalitions, such as the von Neumann-Morgenstern characteristic function. Because there are numerous possible transformations, the question arises as to which one provides the most accurate basis for prediction of payoffs.The laboratory experiment tested three such transformations - the mixed strategy characteristic function, the pure strategy characteristic function, and the Harsanyi threat function. Payoff predictions from two solution concepts (Shapley value, nucleolus) were computed on the basis of each of these transformations, making a total of six theories under test.Results of the study show, in general, that payoff predictions based on the Harsanyi threat function and on the mixed strategy characteristic function were more accurate than those based on the pure strategy characteristic function. The most accurate theories were the Shapley value computed from the Harsanyi function, the nucleolus computed from the Harsanyi function, and the Shapley value computed from the mixed strategy characteristic function. Less accurate were the nucleolus computed from the mixed strategy characteristic function and both the nucleolus and the Shapley value computed from the pure strategy characteristic function.This research was supported by grants SOC-7726932 and SES-8319322 from the National Science Foundation.

Ultimatum decision-making: A test of reciprocal kindness

While fairness is often mentioned as a determinant of ultimatum bargaining behavior, few data sets are available that can test theories that incorporate fairness considerations. This paper tests the reciprocal kindness theory in Rabin (1993 Incorporating fairness into game theory and economics, The American Economic Review 83: 1281-1302) as an application to the one-period ultimatum bargaining game. We report on data from 100 ultimatum games that vary the financial stakes of the game from $1 to $15. Responder behavior is strongly in support of the kindness theory and proposer behavior weakly in support of it. Offer percentages and past offers influence behavior the most, whereas the size of the pie has a marginally significant effect on offer percentages. The data is more in support of reciprocal kindness than alternative theories of equal-split or learning behavior, although the data also weakly support a minimum percentage threshold hypothesis. As a whole, our results together with existing studies suggest that, for smaller stakes games, fairness considerations dominate monetary considerations. This has implications for more complicated naturally occurring bargaining environments in which the financial stakes can vary widely.     

A comparison of models for strategic planning,risk analysis and risk management

Summary Risks, uncertainties in firms and their environment are increasingly dealt with strategic planning, risk analysis and risk management. The present state of strategic planning enables us to consider the greatest part of internal and environmental risks mainly qualitatively - due to the fact that the majority of planning models used are of a deterministic type.The application of CAPM in strategic planning could take risks into account explicitly and maximize the expected value of the firms' common stock. Linked to a corporate simulation model or a DSS it could generate a series of values for the expected rate of return, its standard deviations as well as other output variables important for the management. The difficulties of the use of CAPM are numerous but an attempt to optimize the value of the firm would be a big step in developing new powerful instruments for evaluating the economic consequences of alternative strategies. The problems of CAPM lead to the considerations of the application of stochastic programming in strategic planning. For special cases solution methods can be developed and applied. The implementation of the Decision Support System in strategic planning could help to find the best decision in an interactive way - as suggested in this paper for the case of strategic marketing planning. DSS renders the consideration of other factors relevant to strategic decisions possible; businesses need not be reduced to portfolio terms. The limitations of CAPM, stochastic programming and the difficulties of the implementations of DSS for strategic planning could be partially avoided through the concept of Risk Management. On this concept strategic planning represents only one instrument of Risk Management and is a powerful tool of risk identification. In this paper the other instruments have been shortly demonstrated for the cases of product reliability and risks in relation with foreign countries. The development of new instruments for special cases (e.g., siting problems, specific strategic decisions, etc.), the considerations of risk behavior in individual, group and inter-organizational or even international decision making are now the main topics in the urgent task of research in risk management.     

Giving in the face of risk

Decisions about how to share resources with others often need to be taken under uncertainty regarding its allocational consequences. Although risk preferences are likely important, existing research is silent about how social and risk preferences interact in such situations. In this paper we provide experimental evidence on this question. In a first experiment givers are not exposed to risk while beneficiaries’ final earnings may be larger or smaller than the allocation itself, depending on the realized state of the world. In a second experiment, risk affects the earnings of givers but not of beneficiaries. We find that individuals’ risk preferences are predictive for giving in both experiments. Increased risk exposure of beneficiaries tends to decrease giving whereas increased risk exposure of givers has no effect. We propose a simple non-linear generalization of a model allowing for other-regarding preferences, ex-post and ex-ante fairness, and risk aversion. We find some support for it in our data when risk is on the beneficiaries’ side but less so when risk is on the givers’ side. Our results point to the importance of the further development of models of social preferences that also incorporate risk preferences.     

Sophisticated voting under the plurality procedure: A test of a new definition

The Niemi-Frank definition of sophisticated voting can now be evaluated on two grounds. First, we can compare our definition to Farquharson's. For the most part, the two definitions yield identical outcomes. Both pickCondorcet winners a very high proportion of the time and prevent the selection of Condorcet losers. The major differences are in the logic underlying the two definitions and in the rate of determinacy of outcomes. Here there is a tradeoff. The logic underlying the Farquharson model is especially persuasive, although it is our feeling that the Niemi-Frank definition comes closer to mirroring the way in which voters might actually analyze a plurality situation. In any case, the price paid by the Farquharson definition for its ironclad logic is a much higher rate of indeterminacy. In over half of the cases, the Farquharson logic fails to lead to any conclusion whatsoever. The Niemi-Frank definition yields many more determinate situations, with mostly Condorcet winners and with strategies that make good, if not completely unassailable sense. A second way of evaluating the Niemi-Frank definition is in comparison with sincere voting. A commonly-cited shortcoming of plurality voting is that often fails to choose a Condorcet winner. As we notedearlier, sophisticated plurality voting, unlike binary voting, is imperfect in this respect. Nonetheless, even taking account of the indeterminacy thatremains in the Niemi-Frank definition, sophisticated voting picked a Condorcet winner about 10 percent more frequently than did sincere voting as well as eliminating the possibility of a Condorcet loser being chosen. By this measure, the Niemi-Frank definition is not only acceptable but suggests that this form of strategic behavior actually leads tobetter outcomes. By proposing and now by testing a new definition of sophisticated voting under plurality rule, we have begun to make some headway on understanding strategic behavior and its effects in an outwardly simple yet deceptively complex voting system. We are, of course, far from finished. Most significantly, our definition applies to only three alternatives, and Farquharson's (even if one is willing to live with its high indeterminacy) becomes extraordinarily cumbersome with more than three alternatives? In any event, the results of this foray into sophisticated nonbinary voting suggests once again that strategic behavior, rather than making things worse, improves the chances that the outcome will be the one most favored by the majority criterion.     

Incumbent vulnerability and entry in gubernatorial elections: The case of former governors

The vulnerability hypothesis predicts strategic, quality candidates only challenge weak incumbents. House election studies support this hypothesis. State level analyses produce mixed results. We test whether incumbent vulnerability affects the entry of one kind of strategic actor – former governors. Former governors are an ideal test case. Having already served in the state's highest office, they represent the highest quality and perhaps most strategic candidates who run for state office. Our results show that performance in the previous election, one measure of incumbent vulnerability, does not affect former governor entry. However, incumbent vulnerability measured as recent economic performance and number of other quality candidates appearing in a former governor's party primary does affect entry in general elections.     

Marriage motivated population movement in the outskirts of Beijing

An analysis of migration among the rural population of China for reasons associated with marriage is presented. Data are from a sample survey undertaken in the outskirts of Beijing in 1982. The authors conclude that marriage is a major cause of rural-urban migration, particularly among women aged 20-29. They suggest that traditional attitudes toward marriage have helped to reinforce a marriage market in Chinese cities that creates a demand for young women from rural areas.     

A test of three hypotheses concerning attributions toward female promiscuity

We performed two experiments to test three alternative hypotheses concerning negative attributions toward sexually promiscuous females. The first two possibilities are based on female-to-female negative attributions. The first hypothesis, the Competition Hypothesis, states that females could be using a negative attribution towards other females for derogation purposes when in competition for a mate. Second, the Self-esteem Hypothesis states that females could be using negative attributions towards other females to build Self-esteem. Finally, according to the Social Norm Hypothesis, both males and females see female promiscuous behaviors as deviant thereby resulting in negative attributions towards the women who perform them. In both experiments, the Social Norm Hypothesis received more support than the other two hypotheses.
