| Una empresa innovadora que inicia en el mercado es conocida en la literatura como Start-Up; esté tipo de firmas al ser evaluadas con los métodos tradicionales (tasa interna de retorno, TIR; valor actual neto, VAN y relación benéfico-costo, B/C) son generalmente rechazadas debido a que no cuentan con información económico-financiera suficiente. El objetivo de éste trabajo fue determinar si la incorporación de las metodologías Opciones Reales y Valores Críticos a la evaluación tradicional agregan valor a empresas Start-Up. El caso que se trató fue el de una planta de bioplásticos. Para calcular la opción de compra al aumentar la producción se utilizó el método de Black-Scholes, que consiste en una ecuación y cinco variables. Para calcular el beneficio... |

| We estimate in this paper the market risk implied by the prices of different options traded in the Brazilian stock market. The fundamental theory to handle this problem is the one implied by the Arrow-Debreu contingent claim concept. Using that theory, we are able to construct the term structure of market risk, and to obtain a surface that provides slices for a particular “volatility smile.” The methodology that we use follows the one proposed by Shimko (1993), which is able to calculate a non-lognormal probability density function (PDF) consistent with the volatility observed in a relatively small sample of option prices. This methodology goes beyond the one proposed originally by Black and Scholes (1973), since it does not require log-normality of the... |

| Revenue insurance represents an important new risk management tool for agricultural producers. While there are many farm-level products, Group Risk Income Protection (GRIP) is an area-based alternative. Insurers set premium rates for GRIP on the assumption of a continuous revenue distribution, but discrete events may cause the actual value of insurance to differ by a significant amount. This study develops a contingent claims approach to determining the error inherent in ignoring these infrequent events in rating GRIP insurance. An empirical example from the California grape industry demonstrates the significance of this error and suggests an alternative method of determining revenue insurance premiums. |
