On the role of market insurance in a dynamic model

Durables like cars or houses are a substantial component in the balance sheets of households. These durables are exposed to risk and can be insured in the market. We build a dynamic model in which agents have three possibilities to cope with the risk exposure of the durable stock: (i) purchase of market insurance, (ii) buffer-stock saving of the riskless asset or (iii) adjustment of the durable stock. We calibrate our model to the US economy and find a small role for market insurance.

Premium setting and bank behavior in a voluntary deposit insurance scheme

This study analyzes the effect of premium rates on banks’ incentives to join a deposit insurance scheme and their incentives to invest in risky projects under a voluntary deposit insurance scheme. We find that in order to maximize social welfare, the insurance agency must either set the premium rate to be low so as to attract all banks to join the insurance scheme, or not to have the deposit insurance at all. However, the low premium rate in the voluntary scheme does not balance the budget of the deposit insurance. We also show that in the compulsory deposit insurance scheme, however, it is possible to impose an optimal premium rate that can balance the insurance agency’s budget and achieve the highest social welfare. The results also present the dominance of the compulsory scheme over the voluntary scheme in terms of maximizing social welfare and balancing the budget.

Screening equilibria in experimental markets

We conduct an experimental test of a screening model of an insurance market with asymmetric information. We first conduct three sessions in which the proportion of high risk buyers is such that a separating equilibrium should exist. We then conduct three more sessions in which the only change we make is decreasing the proportion of high risks such that the equilibrium is now a pooling equilibrium. In both treatments, the observed behavior converges to the equilibrium prediction.

The Dynamic Impact of Macro Shocks on Insurance Premiums

We develop a model that investigates the relation between insurance premiums and macroeconomic variables, including oil price, interest rate, aggregate supply, and aggregate demand. We then use a multivariate structural vector error correction model to distinguish the effects arising from permanent and transitory components of insurance premiums. Changes in the transitory component indicate that our model captures key historical events. Although real shocks originating from oil price and aggregate supply explain the behavior of insurance premiums well, we show that financial market shocks are the main driving force behind the recent increasing volatility in insurance premiums in the U.S. market.

Insurer's insolvency risk and tax deductions for the individual's net losses

Using the representative agent approach as in Kaplow (Am Econ Rev 82:1013–1017, 1992b), this paper shows that providing tax deductions for the individual’s net losses is socially optimal when the insurer faces the risk of insolvency. We further show that the government should adopt a higher tax deduction rate for net losses when the insurer is insolvent than when the insurer is solvent. Thus, tax deductions for net losses could be used to provide an insurance for individuals against the insurer’s risk of insolvency. These findings could also be used to explain why a government provides supplementary public insurance or government relief. Finally, we discuss that, if the individuals are heterogeneous in terms of loss severity, loss probability, or income level, providing a tax deduction for the individual’s net losses may not always achieve a Pareto improvement, and cross subsidization should be taken into consideration.

Adverse selection and the market for annuities

Adverse selection is often blamed for the malfunctioning of the annuities market. We simulate the impact of adverse selection on the consumption allocation of annuitants under alternative parameter values, and explore the resulting welfare implications. We show that, for most parameter values, the welfare losses associated with equilibriums that are subject to adverse selection correspond to a loss of wealth of around one percent in a first-best equilibrium. These losses are smaller than the corresponding losses associated with equilibriums with no access to an annuity market by an order of magnitude of ten. The existence of substitutes for annuities such as a bequest motive or a social security system intensifies the adverse selection but reduces its welfare impact.

Heterogeneous time varying transaction costs and asset pricing in international equity markets

In this paper, we examine the time variation in transaction costs relative to excess returns, in a panel consisting of 10 international equity indices over the time period 1984–2005. This is undertaken by extending the consumption CAPM (CCAPM) model proposed by Campbell and Shiller (Rev. Financ. Stud. 1:195–228, 1988) to incorporate time varying proportional transaction costs. We rigorously address both the cross-country heterogeneity in the estimated model and endogeneity. We find strong evidence that suggests transaction costs should be included as an additional explanatory variable in the CCAPM. This leads to the conclusion that transaction costs should be included in asset pricing models as their stochastic process impacts directly on private consumption expenditure.

Does Bancassurance Reduce the Price of Financial Service Products?

I assess the impact of bancassurance on the price of retail financial services. I find that service fees in a product bundle increase less than proportionally to the number of services; that an increase in the number of clients in each product bundle market reduces fees by 1.5%; that the degree of competition in the markets of each bundle also reduces fees; that premium products have higher average costs; and finally, that cross-holdings reduce prices by about 5% and bancassurance reduces prices by just over 6%. The price reduction declines if both strategies are combined.

An alternative interpretation of the discontinuity in earnings distributions

We show that the asymmetric effects of income taxes and special items for profit and loss firms contribute to a discontinuity at zero in the distribution of earnings. Income taxes draw profit observations towards zero while negative special items pull loss observations away from zero. These earnings components are thus expected to contribute to a discontinuity even in the absence of discretion. We show our results are not an artifact of deflation and that other common components of earnings do not have similar effects on the earnings distribution around zero.

The Effect of Time-on-Market and Location on Search Costs and Anchoring: The Case of Single-Family Properties

Regarding single-family residential properties purchased for investment (non-owner occupied) we examine whether out-of-state buyers pay more than in-state buyers. We focus on the effects of search costs and anchoring. We use data on 2,828 Las Vegas non-owner occupied (investor) residences, 40% of which are purchased by non-local investors. We find that the location of the property affects the empirical results. Specifically, search cost and anchoring effects that appear significant when the location of the property is ignored disappear when location is introduced as an independent variable.

Valuation of loss firms in a knowledge-based economy

Recent research in accounting has documented a substantial increase in the number of loss firms. Existing theories on the valuation of loss firms are based on adaptation/abandonment options or limited liability, assuming that these firms are operationally distressed. In this paper, we show that many loss firms do not fit this stereotype and identify the primary value drivers of this new type of loss firms. Our analysis helps resolve the puzzling negative relation between earnings and market value documented in prior research. Overall, our findings underscore the importance of “hidden assets” or intangibles in the study of loss firms.

Securities Transaction Tax and Market Efficiency: Evidence from the Japanese Experience

This study examines the effect of transaction costs on the time series behavior of stock returns over a period surrounding the April 1989 changes in tax rates on securities transactions and capital gains in Japan. We find significant decreases in estimates of the first-order autocorrelation in returns for Japanese stocks listed in Japan, but no changes for Japanese stocks dually listed in the United States as American Depository Receipts (ADRs), which were not subject to the tax law change. We also find lower price basis between the ADRs and their underlying Japanese stocks. These results are consistent with the hypothesis that a reduction in transaction costs improves the efficiency of the price discovery process.

Retail Investors and the Trading of Treasury Securities

I analyze implicit transaction costs of trading government debt securities on the Spanish stock exchanges (SE) electronic trading system. The SE’s multilateral system is used mainly as an outlet for retail investors to liquidate Treasury accounts positions before maturity. I compare identical Treasury security trades on the same day in two different markets: the SE and the interdealer market. By analyzing these yield spreads I learn more about the behavior of the markdowns included in the retail prices from the institutional prices. I find evidence that these yield premia depend on traditional features to explain wholesale market liquidity premia.

Transaction Costs and Price Volatility: New Evidence from the Tokyo Stock Exchange

We investigate the volatility impacts of the full commission deregulation in Japan in October 1999, and find that the deregulation overall tends to significantly increase price volatility in the Japanese equity market, using alternative model specifications and control variables. This finding contrasts with previous evidence that implies a positive relation between transaction costs and price volatility, while consistent from the converse with the hypothesis proposed by Stiglitz (1989) and Summers and Summers (1989). Our results suggest that imposing higher transaction costs might still be a feasible policy tool for stabilizing the market by curbing short-term noise trading.

Density estimation through quasi-analytic Monte-Carlo simulation: Options arbitrage with transactions costs

Discretely rebalanced options arbitrage strategies in the presence of transaction costs have path dependent returns that are difficult to model analytically. I instead use a quasi-analytic procedure that combines the computational efficiency of analytical solutions with the flexibility of simulations. The central feature is the estimation of the distribution of returns of the arbitrage strategy by mapping simulated returns percentiles and the input parameter set. Using the estimated density, I evaluate the tradeoff between transaction costs and risk exposure under generalized transaction costs structures that includes bid-ask spread and brokerage commission. I show that the optimal strategy depends on transaction costs, volatility, and option moneyness. Strategies such as rebalancing when the hedge ratio changes by 0.25, balances transaction costs and risk exposure, and can be optimal.

Joint accounting choices: an examination of firms’ adoption strategies for SFAS No. 106 AND SFAS No. 109

We provide insight into an argument that firms minimize the costs imposed by new accounting standards through their adoption choices. Focusing on two standards with potentially large impacts on both balance sheet and income statement accounts for many firms, we present evidence that firms chose their strategies for SFAS No. 106 (OPEB) and 109 (DTAX) jointly rather than separately. We also provide insight into how firms view recurring versus non-recurring charges, and how they weigh the tradeoff between a large one-time (income decreasing) charge against the smaller, but longer lasting effects of amortization.

Asset Price Spillover,Collateral and Crises: with an Application to Property Market Policy

This paper studies the impact of land supply elasticity and land use regulation. For sufficiently adverse shocks constrained entrepreneurs liquidate their assets for debt repayment. This effect can spillover to the residential property market. A crisis occurs when households are forced to default on their mortgages as well. While both converting costs and land use regulation tend to magnify the effect of adverse shock, the former generates an asymmetric effect between a positive and a negative shock on the land market, and the latter tends to raise the likelihood of a crisis, by raising the threshold value of liquidation.

Trading Credit Default Swaps via Interdealer Brokers

Credit default swaps (CDSs) are among the most successful financial innovations of recent years, which is reflected in the rapidly expanding market. CDS trading occurs in the over-the-counter market, which relies heavily on broker intermediation to arrange trades. We provide empirical evidence that liquidity in the voice brokered market varies with the particulars of the CDS contracts and that the differences in market structure is reflected in the costs of liquidity. Moreover, the brokered and direct interdealer trading markets seem to be well integrated; thus the higher liquidity costs in the brokered market may reflect the value of intermediation. Hybrid market structures, which combine voice brokerage with an electronic platform, are discussed as a viable alternative to fully automated trading systems.

Economic consequences of financial reporting changes: diluted EPS and contingent convertible securities

This paper examines the economic consequences of changes in the financial reporting requirements for contingent convertible securities (COCOs). Using a sample of 199 COCO issuers from 2000 to 2004, we find that issuers are more likely to restructure or redeem existing COCOs to obtain more favorable accounting treatment when the financial reporting impact on diluted earnings per share (EPS) is greater and when EPS is used as a performance metric in CEO bonus contracts. These results provide new evidence that managers are willing to incur costs to retain perceived financial reporting and compensation benefits. We also present evidence of significantly negative stock returns around event dates associated with the financial reporting changes, consistent with investor anticipation of the agency costs associated with the rule change.

Individual Agents,Firms, and the Real Estate Brokerage Process

This study examines how individual agents affect house selling prices and time on the market while controlling for brokerage firm-specific effects as well as supply and demand conditions that vary by neighborhood. Firm size effects disappear once firm specialization and agent characteristics are taken into account but geographic concentration by firms leads to higher selling prices. For individual agents, neither sex nor selling own listings affects price or selling time, but there are gains from partnering transactions across firms. Agents who specialize in listing properties obtain higher prices for their sellers while those who specialize in selling obtain lower prices for their buyers. Houses nearer to other transactions of an agent sell for higher prices. Finally, greater scale of listing and selling activity by an agent tends to lower selling price or lengthen the time on the market.
