Abstract
This paper studies the effect of seven types of exchange rate regimes on business cycle synchronization, by using a new dataset on bilateral de-facto exchange rate regimes for the 1973-2016 period. Using the extreme bounds analysis (EBA) methodology, we find that the exchange rate regime is a robust determinant of business cycle synchronization. We find that, compared to country pairs with freely floating arrangements, (i) the correlation coefficient measuring business cycle synchronization is higher by approximately 0.07-0.12 points in countries with no separate legal tenders; (ii) the effect does not always linearly decrease with increasing exchange rate regime flexibility, since the effects of crawling pegs and crawling bands turn out to be insignificant, whereas that of moving bands as a more flexible type of exchange rate regime is positive and significant; and (iii) the effect is stronger for countries with a high degree of financial openness and good institutional quality. The second finding suggests that the role of intermediate exchange rate regimes is more complicated than previously recognized in the literature and deserves more attention. In addition, we find that (iv) the positive effect of interest is more prominent for countries from the high-income group, in contrast to the occasionally negative effect of some regimes for other country pairs, and that (v) specialization and fiscal policy integration are factors that influence the effect of exchange rate regimes on business cycle synchronization.

Notes
See for example Klein and Shambaugh (2006) for the effect of exchange rate regimes on international trade, Harms and Knaze (2021) for the effect on FDI or Ghosh et al. (2014) for the effect on inflation. Further, exchange rate regimes have been found to significantly affect GDP growth (Levy-Yeyati and Sturzenegger 2003), terms of trade (Broda 2004) or other policy variables [e.g.][onmonetarypolicy] (Obstfeld et al. 2005).
The dataset with further description is available at: https://www.international.economics.uni-mainz.de/data-on-bilateral-exchange-rate-regimes/ In some part of the analysis, we also test the specification by including the \(Regime_{FF}\) dummy that takes a value of one if at least one country from a given country pair had a freely falling exchange rate regime at a given period.
Another approach would be to use an average value of the exchange rate regime measure for each period. However, taking averages would leave us with non-integer values. For example, if a country had a crawling peg (Regime 4) and later on adopted a crawling band (Regime 5). To circumvent this, we conduct analysis based on yearly data of all relevant variables. The results are part of the robustness check to alternative indicators, which we mention again later.
We follow Levine and Renelt (1992) and Sala-I-Martin (1997) to choose 3 as the number of variables for combinations in EBA regressions. Techniqually, it is also fine to choose a bigger number as the criteria. However, to our understanding of the method, this number should not matter too much for the results since we make ultimately all combinations in the rolling windows. In results not reported in the paper, we tried to use 4 as the number of explanatory variables, the coefficients of ERR dummies stay rather similar. The results are available upon request.
In one of our robustness checks, we will replace country-specific variables by time-variant country fixed effects in line with Harms and Knaze (2021). Note, however, that we do not include country-pair fixed effects since our main variable of interest — the bilateral de-facto exchange rate regime — exhibits little time variation.
In addition, we find that our dummy variable \(Regime_{FF}\) dummy has an EBA robust negative coefficient: country pairs where at least one country’s regime is classified as freely falling have substantially less synchronised business cycles compared to the country pairs with free floating regimes. This is in line with our intuition: if countries with freely falling exchange rate regime suffer severe financial and economic crisis, then the business cycles get significantly out of synchronization compared to countries that are currently not in crisis. We have conducted further analysis on \(Regime_{FF}\). Results are available upon request.
We perform the sample split by defining a threshold of 0.5 in the range 0 to 1, where countries with an index of 0.5 or higher are understood as having an open financial account. Results are available upon request.
Our EBA estimation included both different measures of trade intensity as well as the principal component of four different measures to estimate parameters of principal-component model following Inklaar et al. (2008). Since all variables were found to be EBA robust, we use the principal component of the variables in the benchmark results.
We note a difficulty in comparing the strength of the effects between individual determinants: the dummy coefficients for exchange rate regimes are non-standardized, whereas the other variables have standardized coefficients. Despite the standardization, bilateral variables constructed as bilateral correlations such as trade specialisation are difficult to compare with aggregate measures such as trade openness. Therefore, our paper focuses on the relative importance between individual exchange rate regimes for business cycles synchronization.
We have conducted analysis when observations of “Free Falling” regime is included for both the EBA analysis and the reduced model. Results are available upon request.
Note that from cca. 27.000 observations available, the large majority are the freely floating regimes.
We are grateful to two anonymous referees for motivating us to conduct analysis for this section.
