This paper examines the long-term trends observed in the standard of living of the Colombian population during the past one hundred years, with special attention on health. We construct a historical index of human development for Colombia (HIHDC) for the 19th and 20th centuries by gender. We…

We study connectedness and causality between oil prices and exchange rates dynamically. Using data on the WTI and exchange rate returns for six countries in which oil production is a major production activity, we show that oil prices are net receptors of spillovers from excahnge rate markets.…

We carry out a reading analysis that consists of two elements. First, we observe the coherence between monetary policy actions and press releases. In this case, we found that inflation and growth are significant themes in the adoption of the policy measures between September 2004 and March 2016…

In complex systems, homogeneity (i.e. lack of diversity) has been documented as a source of fragility. Likewise, financial sector’s homogeneity has been documented as a contributing factor for systemic risk. We assess homogeneity in the Colombian case by measuring how similar banks are regarding…

Mergers of firms producing complementary products have ambiguous effects on consumer welfare. Consumers benefit if the firm, motivated by the internalized profits created by the complementarity, lowers prices. Consumers are hurt if the firm uses bundles to exert price discrimination, making…

Vacancies are the center of any job creation process. In this paper, we study firms’ hiring behavior in a way that is directly related to vacancies. To understand the dynamic relationship between hires and vacancies, we estimate what we called a hiring function. Even though we cannot observe…

Macroprudential policy in Colombia is described along with a discussion of the main challenges faced by the authorities in implementing it and a review of episodes in which macroprudential measures were taken. An overview and some estimates of their effectiveness in preventing the buildup of…

This paper explores the behavior of Colombia labour market flows. We focus on job creation and job destruction from the plant´s perspective, and on hiring and separations from the worker´s point of view. We show how these labour flows change across different dimensions such as, firm’s size,…

Abstract: The paper provides some evidence on the relevance of global uncertainty and risk aversion and the lesser importance of US interest rates for the global financial and business cycles. As framework, we use a global semi-structural model augmented with financial and…

In this paper we estimate the effect of government consumption shocks on GDP using a panel of 21 developing economies. Our goal is to better understand the reasons for the low fiscal multipliers found in the literature by performing estimations for alternative exchange rate regimes, business-…

We study the relation between oil prices and stock market returns for a set of six countries, including important oil consumers and demanders. We study interconnectedness between oil and stock markets and characterize the dynamics of transmission and reception between them. We test for Granger…

We use hazard models to study the determinants of housing price bubbles’ duration. We answer two related questions: i). Does prolonged domestic monetary policy easing increase the duration of housing price bubbles? And, ii). Does prolonged monetary policy easing in the US influences housing…

The international financial crisis of 2007-2009 strongly affected asset prices, risk and growth in the advanced economies, leading to large capital movements between these economies and the emerging countries. The capital movements were reflected in sharp fluctuations in the emerging countries’…

Can technological misallocation generate financial frictions? We build a theoretical model with testable implications, in which the misallocation between R&D and production activities generates borrowing constraints. The investor offers the innovator a rent that is contingent to the success…

In this paper, we build a heterogeneous agents-dynamic general equilibrium model wherein saving constraints interact with credit constraints. Saving constraints in the form of fixed costs to use the financial system lead households to seek informal saving instruments (cash) and result in lower…

The paper assesses the role of taxes on investment in Colombian firms. The analysis is carried out at the firm level for the period 2003-2014. During this period, the national government set five different tax reforms, including changes in the statutory tax rates, tax credits and incentives for…

Central banks generally target multiple objectives while having at least the same number of monetary instruments. However, some instruments can be inadvertently collinear, leading to indeterminacy and identification failures. Paradoxically, most empirical studies have shied away from this…
