Small Open Economy Business Cycle Research Articles

Informality, labor regulation, and the business cycle

We ask how labor regulation and informality affect macroeconomic volatility and the propagation of shocks in emerging economies. For this, we propose a small open economy business cycle model with frictional labor markets, endogenous labor participation, and an informal sector. Our own calculations from the ENOE national household survey reveal that these three margins are important to account for the labor market dynamics in Mexico. The model is calibrated to the Mexican economy, in particular to business cycle moments for employment and informality. We show that interest rate shocks, which affect specifically job creation in the formal sector, are key to obtain a countercyclical informality rate. In our model, the presence of an informal sector might help to mitigate the impact of a stringent labor regulation on employment and consumption fluctuations. In that sense, it adds flexibility to the economy in its adjustment to shocks, but at the cost of a lower productivity and an excess TFP and output volatility. Reducing the burden of labor regulation to the formal sector might achieve the goal of reducing output volatility while improving at the same time the efficiency in the allocation of resources.

Imported inputs and the countercyclicality of net exports in emerging markets

This paper shows that the strong countercyclicality of net exports observed in emerging market economies can be explained to a large extent by the use of imported inputs in production. We build a single-sector small open economy business cycle model featuring imported inputs and variable capital utilization in production, and a working capital constraint. The model yields countercyclical net exports and realistic business cycle dynamics. The magnitude of the countercyclicality of net exports increases with the share of imported inputs. The elasticity of substitution between domestic and imported inputs is also critical in obtaining this result. The model also attributes an important role to import prices in matching the business cycle facts in emerging markets.

Informality, Labor Regulation, and the Business Cycle

We analyze the joint impact of labor regulation and informality on macroeconomic volatility and the propagation of shocks in emerging economies. For this, we propose a small open economy business cycle model with frictional labor markets, endogenous labor participation, and an informal sector. Our own calculations from the ENOE national household survey reveal that these three margins are important to account for the labor market dynamics in Mexico.

Reducing the burden of labor regulation to the formal sector might achieve the goal of reducing output volatility while improving at the same time the efficiency in the allocation of resources.

Remittances, entrepreneurship, and employment dynamics over the business cycle

We incorporate remittances and micro-entrepreneurship (self-employment) into a small open economy business cycle model with capital and labor market frictions. Countercyclical remittances moderate the decline of households' consumption during recessions. These remittances also are used to finance the start-up costs of microenterprises that bolster households' income during economic downturns. We show that the positive income effect from countercyclical remittances also leads to a decrease in salaried labor supply, which generates offsetting upward pressure on wages during recessions and adversely affects the recovery of the economy. Consistent with the microeconomic evidence, the behavior of remittances decisively affects labor force participation and the composition of employment between non-salaried and salaried employment over the business cycle. The model delivers labor market and aggregate cyclical dynamics that are consistent with the Mexican data, including a highly volatile and countercyclical unemployment rate.

Macroprudential Policy and Labor Market Dynamics in Latin America

This paper builds a small open economy business cycle model with labor and financial market frictions that incorporates frictional, endogenous self-employment entry and a link between formal credit markets, informal credit, and the labor market. The paper then shows that the model is consistent with the cyclical behavior of both labor and credit markets in Latin American economies and analyzes the aggregate consequences of cyclical macroprudential policy for labor market and aggregate dynamics. It is found that a policy that reduces credit fluctuations successfully reduces consumption, investment, and output volatility, but generates substantially higher unemployment fluctuations in response to productivity shocks. Moreover, the policy increases the volatility of all these variables in response to net worth shocks. The link between formal credit markets, input credit between firms, and self-employment plays a key role in explaining the adverse impact of macroprudential policy on unemployment dynamics. The findings point to potential gains from policy complementarities between macroprudential regulation and active labor market interventions over the business cycle.

Remittances, Entrepreneurship, and Employment Dynamics Over the Business Cycle

We incorporate remittances and microentrepreneurship (self-employment) into a small open-economy business cycle model with capital and labor market frictions. Countercyclical remittances moderate the decline of households' consumption during recessions. These remittances also are used to finance the start-up costs of microenterprises that bolster households' income during economic downturns. However, the positive income effect from countercyclical remittances also leads to a decrease in salaried labor supply, which generates offsetting upward pressure on wages during recessions and adversely affects the recovery of the salaried sector. Therefore, the behavior of remittances decisively affects labor force participation and the composition of employment between nonsalaried and salaried employment over the business cycle. The model delivers labor market and aggregate cyclical dynamics that are consistent with the Mexican data.

Macroeconomic volatility: The role of the informal economy

Many countries have a large informal economy that is poorly measured in the national accounts. I develop a two-sector small open economy business cycle model where one sector is formal and the other is informal, and explore the effect that the informal sector has on measured business cycles. I show that if the informal economy is poorly measured, the model can generate a volatility of measured consumption that is higher than that of output, as observed in many developing countries and some developed countries, even though actual consumption is not nearly as volatile. My results illustrate the importance of the informal sector and its mis-measurement in understanding measured cyclical fluctuations.

The composition and cyclical behavior of trade flows in emerging economies

Les données de flux commerciaux montrent que la composition et les propriétés cycliques des importations sont identiques dans les pays développés et émergents, mais que ce n’est pas le cas pour les exportations. Contrairement aux pays développés, (i) les pays émergents exportent peu ou seulement un ensemble restreint de biens d’équipement et (ii) les exportations de biens d’équipement, mais aussi dans leur ensemble, ont tendance à être acycliques. L’absence de procyclicité des exportations explique la forte contracyclicité des balances commerciales des pays émergents observée dans les études précédentes. Un exercice quantitatif montre comment le modèle standard de cycle d’une petite économie ouverte peut être amélioré pour les pays émergents en incorporant certaines de ces caractéristiques.

Interest Rates and Business Cycles in Emerging Economies: The Role of Financial Frictions

Countercyclical country interest rates have been shown to be both a distinctive characteristic and an important driving force of business cycles in emerging market economies. In order to account for this, most business cycle models of emerging market economies have relied on ad hoc and exogenous countercyclical interest rate processes. This paper embeds a financial contract a la Bernanke et al. (1999) in a standard small open economy business cycle model that endogenously delivers countercyclical interest rates. The model is then applied to the data, drawn from a novel panel dataset for emerging economies that includes financial data, namely sovereign and corporate interest rates as well as leverage. It is shown that the model accounts well not only for countercyclical interest rates, but also for other stylized facts of emerging economies` business cycles, including the dynamics of leverage.

Private consumption and sector price behaviour in the Spanish economy: a business cycle approach

In this article we examine the consequences of introducing tradable, nontradable and investment goods in a small open economy business cycle model in the case of Spain. The stochastic simulation of the model and its comparison to the Spanish economic data show that the model is able to mimic two prominent features of the Spanish cycle: (1) the dual inflation phenomenon, that is, the cyclical properties of the divergent behaviour between nontradable and tradable prices; and (2) the high volatility of private consumption relative to the volatility of output, a feature known as the Dolado et al. puzzle.

Transmission mechanisms of real stochastic shocks in a small open economy

We offer a qualitative evaluation of the transmission mechanisms of two real shocks, a productivity shock and a government expenditure shock in Walrasian business cycle models. The analysis is developed in a monetary small open economy business cycle model, a set-up general enough to study the effects of the two shocks on both real and nominal variables. Qualitative and graphical displays indicate properties of Real Business Cycles that are able to reproduce observed cyclical patterns, independently of the calibration used for different economies. These qualitative findings match the quantitative results found in the literature, and rationalize some disparity findings (such as the cyclicity pattern of prices) and failures (such as the Dunlop–Tarshis observation). We suggest that understanding the underlying qualitative intuitions of these models may be of great help in tackling new puzzles in this area.

The composition and cyclical behavior of trade flows in emerging economies

The composition and cyclical properties of imports are similar in developed economies and emerging economies (EM) but this is not the case for exports. Unlike developed economies, (i) EM export few or only a selective set of capital goods and (ii) capital good and overall exports tend to be acyclical. The lack of procyclicality in exports helps to explain the strong countercyclicality of EM trade balances observed in previous studies. A quantitative exercise demonstrates how the standard small open economy business cycle model could be improved upon by incorporating some of these features.

Trade flows data show that the composition and cyclical properties of imports are similar in developed economies and emerging markets (EM) but this is not the case for exports. Unlike developed economies, (i) EM export few or only a selective set of capital goods and (ii) capital good and overall exports tend to be acyclical.

Risk Matters: The Real Effects of Volatility Shocks

This paper shows how changes in the volatility of the real interest rate at which small open emerging economies borrow have a quantitatively important effect on real variables like output, consumption, investment, and hours worked. To motivate our investigation, we document the strong evidence of time-varying volatility in the real interest rates faced by a sample of four emerging small open economies: Argentina, Ecuador, Venezuela, and Brazil. We postulate a stochastic volatility process for real interest rates using T-bill rates and country spreads and estimate it with the help of the Particle filter and Bayesian methods. Then, we feed the estimated stochastic volatility process for real interest rates in an otherwise standard small open economy business cycle model. We calibrate eight versions of our model to match basic aggregate observations, two versions for each of the four countries in our sample. We find that an increase in real interest rate volatility triggers a fall in output, consumption, investment, and hours worked, and a notable change in the current account of the economy.

Risk Matters: The Real Effects of Volatility Shocks

We show how changes in the volatility of the real interest rate at which small open emerging economies borrow have an important effect on variables like output, consumption, investment, and hours. We start by documenting the strong evidence of time-varying volatility in the real interest rates faced by four emerging economies: Argentina, Brazil, Ecuador, and Venezuela. We estimate a stochastic volatility process for real interest rates. Then, we feed this process in a standard small open economy business cycle model. We find that an increase in real interest rate volatility triggers a fall in output, consumption, investment, hours, and debt. (JEL E13, E20, E32, E43, F32, F43, 011)

Financial market participation and the developing country business cycle

Abstract I explore the implications of limited participation in financial markets on a standard small open economy business cycle model. Despite its parsimony, the limited participation model developed in this paper improves over the standard model in terms of explaining two important features of business cycle facts of developing countries: high volatility of consumption, and high negative correlation between the trade balance and output. Limited participation model is then used to inspect the effects of financial development and integration on macroeconomic volatility. Under a standard calibration, limited participation model leads to the conclusion that financial development and integration are associated with higher investment and output volatility. Effect of more participation on consumption volatility is dependent on the specification of the risk premium function.

Investment‐specific shocks and external balances in a small open economy model

Abstract. We set up a standard small open economy business cycle model driven by government spending shocks, neutral productivity (TFP) shocks, and investment‐specific shocks. The model is calibrated to quarterly Canadian data and its predicted moments and sample paths are compared with their Canadian counterparts. We find that the model captures the dynamics in investment and in the trade balance better than special cases of the model where either one of the productivity shocks is omitted. More specifically, the model matches the variance of the trade balance‐output ratio, its correlation with output and its autocorrelation. It also matches the output‐investment correlation.

How Different is the Cyclical Behavior of Home Production Across Countries?

This paper studies stylized business cycle properties of household production in four industrialized countries (Canada, the United States, Germany, and Japan). We employ a dynamic small open economy business cycle model that incorporates a household production sector. We use the model to generate data on home output, hours worked in the home sector, and hours spent on leisure. We find that in each country, home output is more volatile than market output while home sector hours are about as volatile as those in the market sector. In each country, leisure is the least volatile series. Leisure hours and home hours are countercyclical in all countries, and home output is not highly correlated with market output. Home sector variables are generally less persistent than market variables, and cross-country correlations related to home production tend to be lower than those related to market production. These findings demonstrate that despite some well-known structural differences in labor markets, the cyclical features of home sector variables are similar across the countries we consider.
