En México, la Comisión Nacional Del Agua (CNA), es el organismo responsable de registrar y publicar los resultados de la medición de variables que se obtienen de la red de estaciones metereológicas e hidrométricas. En los últimos años, las redes se han reducido. En algunos ríos, la medición de los escurrimientos, la variable hidrológica más importante, se ha suspendido. En estos casos, la falta de datos históricos provoca que no se pueda realizar una planeación adecuada de los recursos hídricos a nivel local y regional. Por lo anterior, la modelación matemática, en particular con modelos de series de tiempo, se puede desarrollar para generar series sintéticas con la capacidad de reproducir las propiedades estadísticas de los registros históricos... |

The volatility of interest rates is relevant for many financial applications. Under realistic assumptions the term structure of interest rate differentials provides an important prediction of the term structure of interest rates. This paper derives the term structure of differentials in a situation in which two open economies plan to enter a monetary union in the future. Two systems of floating exchange rates prior to the union are considered, namely a free-float and a managed-float regime. The volatility processes of arbitrary term differentials under the respective pre-switch arrangements are compared. The paper elaborates the singularity of extremely short-term (i.e. instantaneous) interest rates under extensive leaning-against-the-wind intervention... |

The process of international interest rate convergence for arbitrary terms (represented by the term structure of interest rate differentials) is derived in a model of a small open economy which faces a purely time-contingent exchange rate regime switch from flexible to fixed rates. Special attention is paid to a situation in which financial markets deem a delay in the regime switch beyond the publicly announced fixing date possible. The closed-form solution of the term structure allows us to analyze the volatility of interest rate differentials thus providing a useful tool for interest-rate-sensitive security valuation and other risk management applications. Furthermore, the model demonstrates that the economy under consideration has to pay for the... |

Agricultural production relies to a great extent on biological processes in natural environments. In addition to volatile prices, it is thus heavily exposed to risks caused by the variability of natural conditions such as rainfall, temperature and pests. With a view to the apparently lacking support of risky farm production program decisions through formal planning models, the objective of this paper is to examine whether, and eventually by how much, farmers’ “intuitive” program decisions can be improved through formal statistical analyses and stochastic optimization models. In this performance comparison, we use the results of the formal planning approach that are generated in a quasi ex-ante analysis as a normative benchmark for the empirically observed... |
