Inefficient sales delays by a durable‐good monopoly facing a finite number of buyers

This article offers a new explanation for unscheduled price cuts and slow adoption of durable goods. We study a standard durable‐good monopoly model with a finite number of buyers and show that this game can have multiple subgame perfect equilibria in addition to the Pacman outcome—including the Coase conjecture. Of particular interest is a class of equilibria where the seller first charges a high price and only lowers that price once some—but not all—high‐valuation buyers purchase. This price structure creates a war of attrition between those buyers, which delays market clearing and rationalizes unscheduled purchase and price cut dates.     

Estimating liquidity premia in the Spanish government securities market

This paper investigates the presence of liquidity premia in the relative pricing of assets traded on the Spanish government securities market. First, a classification of bonds into four different categories based on their degree of liquidity is proposed. Second, liquidity premia are estimated introducing liquidity parameters in the estimation of the zero-coupon yield curve. Results suggest the existence of a liquidity premium for post-benchmark bonds (both strippable and non-strippable). The size of this premium is relatively small. In the case of pre-benchmark bonds, the lack of liquidity does not seem to be priced. It is also shown that these pricing discrepancies are robust to the impact of taxes on bonds.     

American options and callable bonds under stochastic interest rates and endogenous bankruptcy

A new characterization of the American-style option is proposed under a very general multifactor Markovian and diffusion framework. The efficiency of the proposed pricing solutions is shown to depend only on the use of a viable valuation method for the corresponding European-style option and for the transition density of the model’s state variables. Under a Gauss-Markov stochastic interest rates setup, these new American option pricing solutions are shown to offer a much better accuracy-efficiency trade-off than the approximations already available in the literature. This result is also used to price callable corporate bonds under an endogenous bankruptcy structural approach, by decomposing the option to call or default into a European put on the firm value plus two early exercise premium components.     

Tariffs versus VAT in the presence of heterogeneous firms and an informal sector

The debate over the use of tariffs or value added taxes in developing countries has focused on the difficulty of collecting VAT from the informal sector. This paper contributes by considering this issue with heterogeneous firms and endogenous entry. This yields two results. First, a cut in the tariff reduces the size of the informal sector. Second, the imposition of VAT need not increase the size of the informal sector. Turning to simulation results, we find that switching from a tariff to a revenue-neutral VAT increases welfare, in part because of the selection effect generated by heterogeneous firms.     

The influence of remuneration on the behavior of hospital employees in Brazil

The study aimed to analyze the employee's perception of the remuneration systems in two major hospitals in Brazil, one managed by the government and the other by private investors. The sample considered 109 respondents, out of which 54 were from the private hospital and 55 from the public hospital. After data collection on the sample population, perception of remuneration was associated with occupation, gender, age and experience, as suggested by the Upper Echelons Theory. The results show that remuneration is viewed as an instrument of control and behavior or a learning-inducing mechanism; however, the perceptions of employees working in the health area and administrative area were different. These findings show that the influence of fixed pay is different not only for the employees of both areas, but also in relation to the public and private hospital management. It was found that gender is not a determinant factor of behavior and that there were no differences between younger and older employees as well as between more experienced and less experienced employees with respect to the effect of remuneration on behavior. There were no differences in relation to the type of hospital either. In general, the results emphasize the importance of remuneration as an instrument of control and management, either in the context of public or private organizations.     

Investment, credit, and endogenous cycles

This paper presents a general-equilibrium dynamic Ramsey-type model that can generate endogenous cycle. We assume two different representative agents, borrowers and lenders, and financial intermediaries with inside and outside money. We investigate under which conditions this model presents a cyclical relationship between capital and loans. The sources of endogenous fluctuations in this model come from a credit restriction in the representative-borrower problem.
