We propose three analytic approximation methods for numerical valuation of the guaranteed annuity options in deferred annuity pension policies. The approximation methods include the stochastic duration approach, Edgeworth expansion and analytic approximation in affine diffusions. The payoff structure in the annuity policies is similar to a quanto call option written on a coupon bearing bond. To...

This paper proposed to take advantages of resonant ultrasound spectroscopy (RUS) to measure the mechanical properties of human dentin specimen. The resonant spectroscopy of the dentin specimen was obtained between the frequency bands 155 and 575 kHz, and resonant frequencies were extracted by linear predictive filter and then by Levenberg-Marquardt method. By inverse problem approach, 13 experi...

The decision by firms to offer an occupational pension is investigated with a unique linked employer-employee dataset, supplemented with detailed actuarial calculations of the cost to the firms of offering occupational pensions and constructed tax gains from pension contributions versus cash wage, driven by lower tax on wages than on pensions. The tax gains which can be shared between employers...

Financing through crowdfunding is growing rapidly, especially for start-ups. Investment financing via crowdfunding is integrated with the real side of the firm as future consumers may potentially provide all or part of the required resources. We derive the optimal pre-sale crowdfunding contract of a financially constrained monopolist and analyze its implications for production, investment and w...

The literature nds that investors increase portfolio turnover following high returns, explaining it by either overcon dence or skilled trading. This paper develops a theoretical model and shows empirically that team-managed funds trade less after good performance than single-managed funds. The magnitude of this di erential increases with team size. Moreover, the change from singleto team-manage...

Bank-speci…c determinants of bank failure during the …nancial crisis in Colombia are identi…ed and studied using duration analysis. The process of failure of banks and related …nancial institutions during that period can be explained by di¤erences in …nancial health and prudence across institutions. The capitalization ratio is the most signi…cant indicator explaining bank failure. Increases in ...

This paper proposes a computationally efficient algorithm for quantifying the impact of interest-rate risk and longevity risk on the distribution of annuity values in the distant future. The algorithm simulates the state variables out to the end of the horizon period and then uses a Taylor series approximation to compute approximate annuity values at the end of that period, thereby avoiding a c...

Real estate is the most important alternative asset class for pension funds and represents on average more than five percent of their total holdings. We employ a previously unexplored international database to examine the investments of some 880 pension funds in direct real estate and REITs over the 1990-2009 period. We document that larger funds are more likely to invest in real estate interna...

In recent years, the economics of migration literature has shown a substantial growth in papers exploring host country impacts beyond the labour market. Specifically, researchers have begun to shift their attention from labour market and fiscal changes, towards exploring what we might call ‘the wider effects of migration’ on the production and consumption sides of the economy – and the role of ...

We show that fund families allocate their fund managers to different market segments such that their skill is rewarded best. Whether a fund manager’s skill is rewarded by higher alpha depends on the efficiency of the market segment in which she works. Even skilled managers can generate alpha only if the market segment is inefficient. Fund families take this relation between skill and inefficien...
