This work aims to test the equilibrium relations of two international macroeconomics models for Colombia, Chile, Mexico and Brazil. The first model is the rational expectation hypothesis (REH) where three key relations will be tested: Purchasing Power Parity (PPP), Uncovered Interest Rate Parity (UIP) and the Fisher Parity condition. The second model follows the line of though of Imperfect Knowledge Economics (IKE) where two equilibrium relations will be tested. According to IKE, even under the assumption that agents are rational, the presence of speculative behavior in financial markets helps explain the long swings often observed in the behavior of exchange rates. The results support the view that the predictions of the IKE model hold for Colombia, while those of the REH hold for both Brazil and Mexico. Mixed findings are obtained for Chile.

Este documento propone un modelo para la estructura a plazos del riesgo interbancario a partir del spread entre los Interest Rate Swap (IRS) y los Overnight Indexed Swaps (OIS) en dólares durante la crisis financiera 2007-08 y la crisis del euro en 2010. Adicionalmente hace la descomposición del riesgo interbancario entre riesgo de default y no-default (liquidez). Los resultados sugieren que la crisis financiera tuvo importantes repercusiones en la estructura a plazos del riesgo interbancario y sus componentes: en los años previos a la crisis, el riesgo de no-default explicaba la mayor parte del riesgo interbancario; durante la crisis y posterior a ella, el riesgo de default conducía el comportamiento del riesgo interbancario. Adicionalmente, se encuentra que, a partir de la estructura a plazos de cada componente del riesgo interbancario, la crisis financiera se caracterizó por ser un problema más de corto que de largo plazo, en contraste con la crisis del euro de 2010. Estos resultados siguen lo propuesto por Filipovic & Trolle (2012) y dejan importantes implicaciones sobre el riesgo interbancario durante los periodos de stress financiero.

En el presente documento se descompone la estructura a términos de las tasas de interés de los bonos soberanos de EE.UU. y Colombia. Se utiliza un modelo afín de cuatro factores, donde el primero de ellos corresponde a un factor de pronóstico de los retornos y, los demás, a los tres primeros componentes principales de la matriz de varianza-covarianza de las tasas de interés. Para la descomposición de las tasas de interés de Colombia se utiliza el factor de pronóstico de EE.UU. para capturar efectos de spillovers. Se logra concluir que las tasas en EE.UU. no tienen un efecto sobre el nivel de tasas en Colombia pero sí influyen en los excesos de retorno esperado de los bonos y también existen efectos sobre los factores locales, aunque el factor determinante de la dinámica de las tasas locales es el “nivel”. De la descomposición se obtienen las expectativas de la tasa corta y la prima por vencimiento. En ese sentido, se observa que el valor de la prima por vencimiento y su volatilidad incrementa con el vencimiento y que este valor ha venido disminuyendo en el tiempo.

La estimación e interpretación de la estructura a plazo de la tasas de interés es de gran relevancia porque permite realizar pronósticos, es fundamental para la toma de decisiones de política monetaria y fiscal, es esencial en la administración de riesgos y es insumo para la valoración de diferentes activos financieros. Por estas razones, es necesario entender que puede provocar un movimiento en la estructura a plazo. En este trabajo se estiman un modelo afín exponencial de tres factores aplicado a los rendimientos de los títulos en pesos de deuda pública colombianos. Los factores estimados son la tasa corta, la media de largo plazo de la tasa corta y la volatilidad de la tasa corta. La estimación se realiza para el periodo enero 2010 a mayo de 2015 y se realiza un análisis de correlaciones entre los tres factores. Posterior a esto, con los factores estimados se realiza una regresión para identificar la importancia que tiene cada uno de estos en el comportamiento de las tasas de los títulos de deuda pública colombiana para diferentes plazos al vencimiento. Finalmente, se estima la estructura a plazo de las tasas de interés para Colombia y se identifica la relación de los factores estimados con los encontrados por Litterman y Scheinkman [1991] correspondientes al nivel, pendiente y curvatura.

El desarrollo del mercado financiero en Colombia, ha hecho que la integr ación con los merados financieros internacionales sea cada vez más evidente. Es por esto que el estudio del grado de relación de nuestras tasas de interés con las tasas de interés de las tasas internacionales, cobra relevancia. Este estudio, busca evidencia sobre el cumplimiento de la hipótesis de paridad descubierta de intereses y la hipótesis de expectativas racionales, a través del uso de las curvas cero cupón de Colombia y Estados Unidos, siguiendo la metodología derivada del estudio de Bekaert (2002). Se encuentra que el cumplimiento de ambas hipótesis, simultáneamente, no es un hecho común entre los diferenc iales de tasas de Colombia y Estados Unidos. Además, en algunos casos, se encuentra que las hipótesis no se cumplen entre las tasas de interés de la misma nacionalidad.

La computación evolutiva y muy especialmente los algoritmos genéticos son cada vez más empleados en las organizaciones para resolver sus problemas de gestión y toma de decisiones (Apoteker & Barthelemy, 2000). La literatura al respecto es creciente y algunos estados del arte han sido publicados. A pesar de esto, no hay un trabajo explícito que evalúe de forma sistemática el uso de los algoritmos genéticos en problemas específicos de los negocios internacionales (ejemplos de ello son la logística internacional, el comercio internacional, el mercadeo internacional, las finanzas internacionales o estrategia internacional). El propósito de este trabajo de grado es, por lo tanto, realizar un estado situacional de las aplicaciones de los algoritmos genéticos en los negocios internacionales.

This Working Document by Daniel Gros presents a simple model that incorporates two types of sovereign default cost: first, a lump-sum cost due to the fact that the country does not service its debt fully and is recognised as being in default status, by ratings agencies, for example. Second, a cost that increases with the size of the losses (or haircut) imposed on creditors whose resistance to a haircut increases with the proportional loss inflicted upon them. One immediate implication of the model is that under some circumstances the creditors have a (collective) interest to forgive some debt in order to induce the country not to default. The model exhibits a potential for multiple equilibria, given that a higher interest rate charged by investors increases the debt service burden and thus the temptation to default. Under very high debt levels credit rationing can set in as the feedback loop between higher interest rates and the higher incentive to default can become explosive. The introduction of uncertainty makes multiple equilibria less likely and reduces their range.

As an alternative to the present system of intermediation of the German savings surplus, this paper suggests that the risk-adjusted rate of return could be improved by creating a sovereign wealth fund for Germany (designated DESWF), which could invest excess German savings globally. Such a DESWF would offer German savers a secure vehicle paying a guaranteed positive minimum real interest rate, with a top-up when real investment returns allowed. The vehicle would invest the funds in a portfolio that is highly diversified by geography and asset classes. Positive real returns can be expected in the long run based on positive real global growth. Since, in this case, a significant amount of funds would flow outside the euro area, the euro would depreciate, which would help crisis countries presently struggling to revive growth through exports and to close their external deficits so as to recoup their international credit-worthiness. Target imbalances would gradually disappear and German claims abroad would move from nominal claims on the ECB to diversified real and nominal claims on various private and public foreign entities in a variety of asset classes.

Without corrective measures, Greek public debt will exceed 190 percent of GDP, instead of peaking at the anyway too-high target ratio of 167 percent of GDP of the March 2012 financial assistance programme. The rise is largely due to a negative feedback loop between high public debt and the collapse in GDP, and endangers Greek membership of the euro area. But a Greek exit would have devastating impacts both inside and outside Greece. A small reduction in the interest rate on bilateral loans, the exchange of European Central Bank holdings, buy-back of privately-held debt, and frontloading of some privatisation receipts are unlikely to be sufficient. A credible resolution should involve the reduction of the official lending rate to zero until 2020, an extension of the maturity of all official lending, and indexing the notional amount of all official loans to Greek GDP. Thereby, the debt ratio would fall below 100 percent of GDP by 2020, and if the economy deteriorates further, there will not be a need for new arrangements. But if growth is better than expected, official creditors will also benefit. In exchange for such help, the fiscal sovereignty of Greece should be curtailed further. An extended privatisation plan and future budget surpluses may be used to pay back the debt relief. The Greek fiscal tragedy highlights the need for a formal debt restructuring mechanism

This paper derives exact discrete time representations for data generated by a continuous time autoregressive moving average (ARMA) system with mixed stock and flow data. The representations for systems comprised entirely of stocks or of flows are also given. In each case the discrete time representations are shown to be of ARMA form, the orders depending on those of the continuous time system. Three examples and applications are also provided, two of which concern the stationary ARMA(2, 1) model with stock variables (with applications to sunspot data and a short-term interest rate) and one concerning the nonstationary ARMA(2, 1) model with a flow variable (with an application to U.S. nondurable consumers’ expenditure). In all three examples the presence of an MA(1) component in the continuous time system has a dramatic impact on eradicating unaccounted-for serial correlation that is present in the discrete time version of the ARMA(2, 0) specification, even though the form of the discrete time model is ARMA(2, 1) for both models.

In this paper, we study a model economy that examines the optimal intraday rate. In Freeman’s (1996) paper, he shows that the efficient allocation can be implemented by adopting a policy in which the intraday rate is zero. We modify the production set and show that such a model economy can account for the non-uniform distribution of settlements within a day. In addition, by modifying both the consumption set and the production set, we show that the central bank may be able to implement the planner’s allocation with a positive intraday interest rate.

Many key economic and financial series are bounded either by construction or through policy controls. Conventional unit root tests are potentially unreliable in the presence of bounds, since they tend to over-reject the null hypothesis of a unit root, even asymptotically. So far, very little work has been undertaken to develop unit root tests which can be applied to bounded time series. In this paper we address this gap in the literature by proposing unit root tests which are valid in the presence of bounds. We present new augmented Dickey–Fuller type tests as well as new versions of the modified ‘M’ tests developed by Ng and Perron [Ng, S., Perron, P., 2001. LAG length selection and the construction of unit root tests with good size and power. Econometrica 69, 1519–1554] and demonstrate how these tests, combined with a simulation-based method to retrieve the relevant critical values, make it possible to control size asymptotically. A Monte Carlo study suggests that the proposed tests perform well in finite samples. Moreover, the tests outperform the Phillips–Perron type tests originally proposed in Cavaliere [Cavaliere, G., 2005. Limited time series with a unit root. Econometric Theory 21, 907–945]. An illustrative application to U.S. interest rate data is provided

This paper examines the determinacy implications of forecast-based monetary policy rules that set the interest rate in response to expected future inflation in a Neo-Wicksellian model that incorporates real balance effects. We show that the presence of such effects in closed economies restricts the ability of the Taylor principle to prevent indeterminacy of the rational expectations equilibrium. The problem is exacerbated in open economies, particularly if the policy rule reacts to consumer-price, rather than domestic-price, inflation. However, determinacy can be restored in both closed and open economies with the addition of monetary policy inertia.
