Martín Cicowiez 1 and Agustín Filippo 2 Simulations This document presents the group of simulations related to “Macroeconomic Shocks”, and analyzes the results for both the CGE model and the microsimulation model. In a companion document, we provide a detailed description of the reference scenario results (Cicowiez and Filippo, 2018a). In addition, a document that provides an introduction and describes the method and data used in this study is also available (Cicowiez and Filippo, 2018b). 1. Scenarios The apparel industry has expanded rapidly since 2009 with exports especially to the US market helped by preferential access agreements. These exports have been growing at 18 percent per year. Thus, in the first scenario (pwetex) in this set, we simulate an increase in the world export price of Textiles, wearing apparel and leather, the main export product of Haiti (see Table 2.2). In other words, this scenario represents an improvement in the terms of trade for Haiti. Next, the second scenario (pwm) simulates an across the board decrease in the world price of imports; i.e., also an improvement in the terms of trade for Haiti. In the third scenario (remit), 1 Universidad Nacional de La Plata, Argentina. 2 Inter-American Development Bank. we simulate an increase in remittances, both to rural and urban households. Finally, we assess the impact of a negative shock such as the decrease in foreign capital inflows. In this set of simulations, the magnitude of the different shocks was decided rather arbitrarily, with the aim of emphasizing the main qualitative results. As explained, the baseline scenario is the same as in the first set of simulations. On the other hand, the counterfactual model closure rule assumes that adjustments in the direct tax rate clear the government budget. Specifically, the following four simulations were implemented: • pwetex = 25 increase in world export price of Textiles, wearing apparel and leather • pwm = 25 percent decrease in world price of imports • remit = 25 percent increase in remittances • forcap = 25 percent decrease in foreign capital inflows; this is equivalent to an average decrease in capital inflows of 1.5 and 12 percent of baseline GDP and exports, respectively 2. Aggregate Results Figure 2 and Table 3 show key macroeconomic results for the base and the non-base scenarios for the year 2016 (i.e., the year when all scenarios start deviating from the base) and 2030, the last simulation year. In the base scenario, the economy evolves according to recent trends, as described in the companion document that presents the results from the “Government and Institutional Capacity” simulations (Cicowiez and Filippo, 2018a). Figures 3, 4, 5 and 6 summarize the main transmission channels in the pwetex, pwm, remit and forcap scenarios, respectively. In scenarios pwetex and pwm, compared to the baseline, better terms of trade for Haiti lead to improvements in the macroeconomic situation (see Table 1). This includes GDP growth, private consumption and investment, and trade indicators. In the pwetex scenario, the annual growth rate of the GDP at factor cost for the 2013-2030 period rises by 0.9 percentage points. As expected, the increase in the growth rate is higher for Textiles, wearing apparel and leather than for other activities (see Table 2). In addition, the unemployment rate decreases by 11.5 percentage point in 2030 with respect to the baseline scenario. On the other hand, the outward orientation of the expanding industry appreciates the real exchange rate which generates a form of “Dutch disease” for the rest of the tradables (again, see Table 2). In the remittances scenario (i.e., remit), the exchange rate appreciates at the same time as the trade deficit increases with a surge in imports and a decline in exports. Undoubtedly, Dutch Disease effects can be a serious concern (see Katz, 2018). In our case, remittances-induced appreciation of the real exchange rate and the drop in exports are severe in view of the large (absolute) increase in remittances under consideration. In fact, exports in 2030 are 15.8 percent lower than in the base scenario, while the real exchange rate appreciates by 3.1 percent. In the scenario with foreign capital outflows, the decrease in foreign savings has a strong negative impact on investment and consequently growth. Interestingly, in the short run, the real exchange rate depreciation promotes an increase in exports. In the long run, however, the impact of a smaller capital stock dominates and, with the slower growth in GDP, exports and imports decrease. Overall, GDP growth is, on average, 0.4 percentage points lower during 2013- 2030 than in the baseline scenario.

Sectoral Results At the sectoral level, our results show that promoted sectors (pwetex scenarios) and import- oriented sector and non-tradables (remit scenario) are gaining most in terms of VA. In turn, the forcap scenario shows a negative impact across the board, given the smaller capital stock in 2030. In the pwm scenario, the decrease in the price of imported inputs promotes an increase in production in most sectors of the Haitian economy.

Distributive Results As explained in Cicowiez and Filippo (2018b), the microsimulation model can decompose the poverty impact of a given non-base scenario into the following effects related to labor market parameters: unemployment, sectoral structure, relative wages, and average wage. In terms of poverty, our results show that the poverty headcount ratio in the last year of the simulation period falls in the first three scenarios and increases in the last one (forcap) (Table 7). In general, the main drivers of the decrease in poverty are, again, decreases in unemployment and higher average wages. In the remit scenario, increases in non-labor income also contribute to the decrease in poverty, but not so much to the decrease in extreme poverty.

Sensitivity Analysis In a companion document (Cicowiez and Filippo, 2018a), we discuss the relevance of conducting sensitivity analysis when applying the CGE method. In this section, we focus on sensitivity analysis with respect to the values assigned to production and consumption elasticities for the simulations presented in previous sections. Table 4 shows the percentage change in private consumption estimated (i) under the central elasticities, and (ii) as the average of the 500 observations generated by the sensitivity analysis. For the second case, the upper and lower bounds under the normality assumption were also computed; notice that all runs from the Monte Carlo experiment receive the same weight. As can be seen, the results reported above are significant, while estimates presented in Table 1 are within the confidence intervals reported in Table 4. For example, there is virtual certainty that the forcap scenario has a negative effect on private consumption.
