Labor Income Risk and Car Insurance in the UK

Microeconomic theory shows that only under certain conditions higher background risk increases the propensity to insure against independent marketable risks. We provide empirical evidence for the case of labor income risk and car insurance in the UK. The main result is that households with higher labor income risk spend more on insurance. This finding is consistent with microeconomic theory if the utility function is of the HARA type. Moreover, we find that households spend more on insurance if they participate in the stock market.     

The Demand for Life Insurance Policy Loans

Previous research has examined the demand for life insurance policy loans using aggregate policy loan data. In contrast, we use a detailed household survey data set containing life insurance and policy loan information to alternatively, and in some cases more directly, examine the four hypotheses traditionally associated with policy loan demand. Our research provides the first U.S. evidence (in the post–World War II period) in support of the policy loan emergency fund hypothesis. In particular, we find that the more detailed emergency fund proxies used here reveal a significantly positive relation between loan demand and recent expense or income shocks.     

Don’t lapse into temptation: a behavioral explanation for policy surrender

Many policyholders surrender their life insurance policies early, leading to substantial monetary losses for private households. Surrender can be explained rationally if it constitutes the last resort providing liquidity in the event of an urgent need of cash. Yet we find clear evidence in German panel data that for more than half of all surrendered contracts investors had cheaper options available to provide the required liquidity. This finding demonstrates that there must be other factors influencing this important life decision. We provide a behavioral explanation, focusing on the role of individual decision heuristics, financial literacy, and financial advice. In particular, we show that financial literacy and financial advice can mitigate the behavioral temptation to lapse, while the tendency to rely on heuristics increases lapse probability.     

Lapses in long-term care insurance

About a quarter of long-term care insurance (LTCI) policy holders aged 65 let their policies lapse before death, forfeiting all benefits. We find that lapse rates are substantially higher among the cognitively impaired in the Health and Retirement Study. This generates a pernicious form of dynamic advantageous selection, as the cognitively impaired are more likely to use care. Simulations show that an inappropriately optimistic asset drawdown path further increases the individual welfare cost of unanticipated lapses. Meanwhile, we find evidence of a significant but very small role for either strategic or financial motives for lapsing.     

Commitment and Lapse Behavior in Long‐Term Insurance: A Case Study

This article presents a case study of a portfolio of individual long‐term insurance contracts sold by a Spanish mutual company. We describe the risk levels, the rating structure, and the implied cross‐subsidies on a portfolio of policies providing health, life, and long‐term care insurance. We show evidence of reclassification risk through the history of disability spells. We also analyze the lapse behavior and seek to provide a rationale for the portfolio’s dynamics. We discuss the lack of commitment from the policyholders (lapses) and from the mutual company (which took a run‐off decision). Finally, we draw conclusions regarding the design of such contracts.     

Can the Life Insurance Market Provide Evidence for a Bequest Motive?

Using U.K. microeconomic data, we analyze the empirical determinants of participation in the life insurance market. We find that term insurance demand is positively correlated with measures of bequest motives like being married, having children, and/or subjective measures of strong bequest motives. We then show that a life‐cycle model of life insurance demand, saving, and portfolio choice can rationalize quantitatively the data in the presence of a bequest motive. These findings provide evidence supporting the presence of a bequest motive.     

Household Life Cycle Protection: Life Insurance Holdings, Financial Vulnerability, and Portfolio Implications

Using the Survey of Consumer Finances, we examine the life cycle demand for different types of life insurance. Specifically, we test for the consumer's aversion to income volatility resulting from the death of a household's wage‐earner through the purchase of life insurance. We first develop a financial vulnerability index to control for the risk to the household. We then examine the life cycle demand for life insurance using several definitions of life insurance. We find, in contrast to previous research, that there is a relationship between financial vulnerability and the amount of term life or total life insurance purchased. In addition, we find older consumers use less life insurance to protect a certain level of financial vulnerability than younger consumers. Secondly, our study provides evidence that life insurance demand is jointly determined as part of a household's portfolio. Finally, we consider the impact of family members' nonmonetary contribution on the household's life cycle protection decision. Our results provide some evidence that households take into account the value of nonmonetary contribution in their insurance purchase.     

Bayesian Modeling of Shock Lapse Rates Provides New Evidence for Emergency Fund Hypothesis

This article considers the problem of estimating shock lapse rates in term life products. Four models are estimated using Bayesian Multiple-Block Gibbs sampling. Goodness-of-fit was compared using weighted average lapse rate fitted error. A simulated data setting was employed to validate the algorithm. Among the methodological contributions to the literature we introduce Bayesian estimation for the lapse rate parameters permitting the identification of parameter distributions as opposed to point estimates. Also we introduce a flexible panel data model accommodating both mixed effects and cross-effects between explanatory variables. The data are weighted in the likelihood function according to their relevance as measured by policy counts. Finally, we utilize a large proprietary dataset of U.S. postlevel premium period term policies that enables superior inference over the parameter estimates. Building on the above improvements and recent data covering the 2008 crisis, we find strong evidence in favor of the Emergency Fund Hypothesis as a driver of shock lapses.     

Consumer Credit Risk Characteristics: Understanding Income and Expense Differentials

This study investigates the consumer credit risk characteristics of Turkish households by analyzing factors related to their income and expense differentials. This study assumes that the income and expense patterns are the key elements of consumer credit risk. Based on a data set ranging from 8,551 to 25,566 households, during the period 2003-5, we employ a logistic regression method to model the determinants of income and expense differentials. We first concentrate on the income-expense balance of households to highlight those that are eligible for consumer credit. We reinforce our results by further analyzing the expenditure behaviors of households to find those that should be either primarily eliminated or targeted for consumer credit by financial institutions. Our overall results provide evidence on the factors identifying household income and expense profiles and, hence, consumer credit risk characteristics of Turkish households.     

The Determinants of Financial Derivatives Use in the United Kingdom Life Insurance Industry

This paper examines the determinants of financial derivatives use in the United Kingdom life insurance industry. We estimate a probit regression model and a Heckman two-stage sample selection regression model using a sample of eighty-eight U.K. life insurers in 1995. Our results indicate that the propensity to use derivative instruments is positively related to a firm's size, leverage and international links, and negatively related to the extent of reinsurance. We also find that mutual life insurance firms have a greater propensity than stock firms to use derivatives. The positive relation with leverage and the negative relation with reinsurance support the hypothesis that U.K. life insurers use derivatives to offset risk, rather than as a speculative means of income generation. Firm size and organizational form are the main influences on the extent of financial derivatives use.     

Empirische Analyse des Einflusses der Überschussbeteiligung auf Neugeschäft und Storno

Recently, German insurers are becoming increasingly interested in assessing and modelling risks related to new business and lapses. The final report of a DAV (German actuarial association) working party on stochastic models for German life insurance companies, released end of 2005, includes some basic approaches for this purpose. However, so far no systematic empirical research has been carried out which provides evidence for an appropriate calibration of such models. This article contributes to closing the gap. It presents the main results of an empirical analysis on the influence of policyholders’ profit participation on new business and lapses based on data about 87 German life insurance companies from 1995—2004. Analyses of regression and correlation were performed for various definitions of the explanatory variable ?profit participation“ (more precisely: the spread to some average value) and with diverse reference parameters for new business and lapses, also considering different types of life insurance. Ultimately, the exploration scarcely yielded evidence for a significant general correlation between policyholders’ profit participation and new business or lapses. However, because of the individuality of life insurance business such an evaluation of historical data can certainly only be regarded as a building block for the overall picture, as is also explained in the paper in some more detail.     

A Dynamic Analysis of the Demand for Life Insurance

Prior research suggests that neither the choice to own life insurance nor the amount purchased is consistently related to the presence of children in the household. While these perplexing findings are based on a static framework, we alternatively examine life insurance demand in a dynamic framework as a function of changes in household life cycle and financial condition. Our results indicate both a statistically and economically significant relation between life events, such as new parenthood, and the demand for life insurance. We also provide new evidence in support of the emergency fund hypothesis: households in which either spouse has become unemployed are more likely than other households to surrender their whole life insurance.     

The role of life insurance in an emerging economy: Human capital protection,assets allocation and social interaction

In this paper, we provide micro-econometric evidence on the determinants of life insurance demand in China, the largest emerging market in the world. We employ the China Household Income Project (CHIP) dataset for the year 2002 in the analysis. The timing is ideal, because of the nature of the less well developed capital markets and social security systems in China in 2002, which sets a suitable stage to study the insurance demand behavior of emerging markets. The results indicate that both the human capital protection motive and the asset allocation motive are important in explaining the purchase of life insurance in China. In addition, we present three empirical regularities: (1) the positive correlation between the returns to human capital and the returns to market portfolio decrease the demand for life insurance; (2) both the current wealth and future income of a household exert curvilinear impacts on life insurance demand; (3) the breadth of a households social connections has substantial impacts on life insurance demand.     

ECONOMIC POLICY UNCERTAINTY AND BOARD MONITORING: EVIDENCE FROM CEO TURNOVERS

We examine whether economic policy uncertainty (EPU) affects a board's chief executive officer (CEO) replacement decision. We find that high EPU reduces the likelihood of forced CEO turnover. Our results support the idea that performance assessment may be more difficult when uncertainty is high. We provide evidence that succession planning may be important to firms in reducing the effects of EPU, as firms with an identifiable heir apparent are not influenced by high EPU. Likewise, voluntary CEO turnovers are not affected by EPU. Overall, our results provide evidence that boards make personnel decisions in response to external macroeconomic pressures.     

Firm Size and Growth in the United Kingdom Life Insurance Industry

This study tests whether the organic growth rates of United Kingdom (UK) life insurance firms are independent of size, as predicted by Gibrat's (1931) Law of Proportionate Effects. Using data for 1987–1996 and the three subperiods, 1987–1990, 1990–1993, and 1993–1996, we find that smaller life insurance firms tended to grow faster than larger ones in the 1987–1990 period and that larger life insurers tended to grow faster than smaller ones in the 1990–1993 and 1993–1996 periods. But over the ten‐year period, we find no significant difference between the growth rates of small and large firms, thus supporting Gibrat's Law as a long‐run tendency in the UK life insurance industry. When we examine firm‐specific determinants of asset growth, we find evidence in 1987–1996 and 1987–1990 that more diversified life insurance firms experienced higher growth rates on average than more specialized life insurers. We also find that the growth of life insurance firms was related to input costs during the 1990–1993 and 1993–1996 subperiods.     

Determinanten der Liquidität in der deutschen Schaden- und Unfallversicherungsindustrie: Bedeutung,Erklärungskraft und Auswirkung der Finanzkrise

The aim of this paper is to analyze the corporate liquidity and its determinants for the German property-liability insurance industry using company-level data for the period 2002–2014. We first investigate the differences in cash holdings across insurers. We then quantify the relative importance of firm-level determinants compared with macroeconomic determinants in explaining insurers’ cash holding choices. In addition, we examine whether the financial crisis of 2008 has an impact on the liquidity situation of insurers. Our results indicate that cash holdings vary significantly across German property-liability insurers. The firm-level determinants size, group affiliation and reinsurance utilization explain more than 50% of the variation. We also find that macroeconomic conditions appear to have negligible effects on the liquidity situation of insurers. In addition, we do not find evidence that the liquidity of German property-liability insurers is influenced by the financial crisis of 2008. The proportion of cash remains relatively stable at 6% of the total assets.     

The Demand for Life Insurance in OECD Countries

This article examines the determinants of life insurance consumption in OECD countries. Consistent with previous results, we find a significant positive income elasticity of life insurance demand. Demand also increases with the number of dependents and level of education, and decreases with life expectancy and social security expenditure. The country's level of financial development and its insurance market's degree of competition appear to stimulate life insurance sales, whereas high inflation and real interest rates tend to decrease consumption. Overall, life insurance demand is better explained when the product market and socioeconomic factors are jointly considered. In addition, the use of GMM estimates helps reconcile our findings with previous puzzling results based on inconsistent OLS estimates given heteroscedasticity problems in the data.     

On the optimal provision of social insurance: Progressive taxation versus education subsidies in general equilibrium

In this paper we compute the optimal tax and education policy transition in an economy where progressive taxes provide social insurance against idiosyncratic wage risk, but distort the education decision of households. Optimally chosen tertiary education subsidies mitigate these distortions. We highlight the quantitative importance of general equilibrium feedback effects from policies to relative wages of skilled and unskilled workers: subsidizing higher education increases the share of workers with a college degree thereby reducing the college wage premium which has important redistributive benefits. We also argue that a full characterization of the transition path is crucial for policy evaluation. We find that optimal education policies are always characterized by generous tuition subsidies, but the optimal degree of income tax progressivity depends crucially on whether transitional costs of policies are explicitly taken into account and how strongly the college premium responds to policy changes in general equilibrium.     

Structuring Deposit Insurance for a United Europe

This paper analyses the difficulties associated with imposing a unified deposit insurance scheme in a unified Europe. Specifically, it investigates the determinants of optimal deposit insurance in light of the Commission's 1994 decision requiring mandatory minimum coverage and encouraging a single unified deposit insurance structure. Issues of deposit insurance premiums and tax burden are analysed in the context of a general equilibrium-type model. The results indicate that taxes, the optimal degree of deposit insurance, and societal risk aversion are all interrelated in such a structure. Therefore, a common insurance system may not be feasible nor appropriate for a first best solution; co-ordination and even unified taxation may be necessary. At the minimum, exceedingly close macroeconomic policy co-ordination will be necessary for the single market for financial services to come to fruition and achieve stability.     

“Skewness and Stock Option Prices”, Hans Gerber and Bruno Landry,July 1997

We determine the optimal amount of life insurance for a household of two wage earners. We consider the simple case of exponential utility, thereby removing wealth as a factor in buying life insurance, while retaining the relationship among life insurance, income, and the probability of dying and thus losing that income. For insurance purchased via a single premium or premium payable continuously, we explicitly determine the optimal death benefit. We show that if the premium is determined to target a specific probability of loss per policy, then the rates of consumption are identical under single premium or continuously payable premium. Thus, not only is equivalence of consumption achieved for the households under the two premium schemes, it is also obtained for the insurance company in the sense of equivalence of loss probabilities.
