Ebook: Presidential Approval in Peru: An Empirical Analysis Using a Fractionally Cointegrated VAR

Presidential approval in Peru depends on economic outcomes. However, voters are unable to distinguish between outcomes resulting from economic policies and those caused by exogenous shocks.
Estimation results from seven Fractional Cointegrated VAR (FCVAR) models suggest that presidential approval increases with the monetary policy interest rate, the terms of trade, and manufacturing
employment; and decreases with the nominal PEN/USD exchange rate and ináation volatility. Additionally, a Principal Components Analysis (PCA) conducted over a large set of macroeconomic
indicators points to a greater ináuence of external over domestic factors in explaining presidential
approval; i.e., economic outcomes that determine the dynamics of presidential approval are not
under presidential control in Peru. It can be argued that these Öndings identify a signiÖcant source
of political instability and a considerable challenge to democratic governance. To the authorsíbest
knowledge, this is the Örst application of fractional cointegration analysis to political economy in
Latin America.

Resumen
La aprobaciÛn presidencial en el Per˙ depende del estado de la economÌa. Sin embargo, los ciudadanos no son capaces de distinguir entre los resultados econÛmicos determinados por las polÌticas
econÛmicas y aquellos que son consecuencia de choques externos. Los resultados de la estimaciÛn
de siete modelos VAR Fraccionalmente Cointegrados (FCVAR) sugieren que la aprobaciÛn presidencial aumenta con la tasa de interÈs de polÌtica monetaria, los tÈrminos de intercambio y el
empleo manufacturero; y disminuye con el tipo de cambio nominal PEN/USD y la volatilidad de
la ináaciÛn. Adicionalmente, un An·lisis de Componentes Principales (PCA) sobre un amplio conjunto de indicadores macroeconÛmicos sostiene que la ináuencia de los factores externos sobre la
aprobaciÛn presidencial es mayor que la de los factores domÈsticos; ie., los resultados econÛmicos
que determinan la din·mica de la aprobaciÛn presidencial no est·n bajo el control del presidente
en Per˙. Esta es la primera aplicaciÛn del an·lisis de cointegraciÛn fraccional para el estudio de la
economÌa polÌtica en AmÈrica Latina, seg˙n el conocimiento del autor.
