Many emerging economies depend on commodities whose prices are volatile. High prices for these commodities naturally help those sectors related to the production of the commodities, but the economic benefits for other sectors are ambiguous. These effects can be different according to the characteristics of the sector, leading to a positive or negative sectoral effect depending on several features. Also, commodity price shocks may affect spending differently according to the characteristics of the population. A feature prevalent in many emerging economies is a low degree of banking penetration, which can affect the magnitude of commodity shocks, because banking services are related to how people save and borrow, affecting their ability to smooth spending when they face income shocks. This dissertation studies the effects of commodity price shocks in exporting economies, analyzing the overall and sectoral effects, as well as the regional effects according to access to banking services among inhabitants. The first chapter analyzes the effect of commodity price fluctuations on both overall and sectoral outcomes in a commodity-exporting economy. Using Chilean and international copper market data, I find positive copper price changes stemming from copper-specific demand shocks generate a broad GDP expansion with no visible decline in the exports of any sector, including manufacturing. These results provide evidence against the Dutch disease hypothesis involving the crowding out effect of commodity price increases on the manufacturing sector. The second chapter studies how features of a commodity-exporting economy such as the degree of substitution between domestic and foreign goods, the income effect on labor supply, and trade policy related to tariffs on imports shape overall and sectoral effects of commodity price shocks. For that, I estimate key structural parameters of a small open economy business-cycle model with 6 sectors by matching my empirical impulse responses and find that a low degree of substitution between domestic and foreign goods explains the positive sectoral effect of a commodity price shock. Then, I evaluate how tariffs on imports shape the effect of commodity price shocks and find low tariffs make the small open economy less sensitive to commodity price shocks when the elasticity of substitution between domestic goods and imports is small. The third chapter studies the relationship between access to banking services and the magnitude of external shocks. Using quarterly data of the number of checking and savings bank accounts per person as an indicator of access to banking services, I analyze the effects of commodity price changes conditional on the number of bank accounts per person across Mexican states. I find decreases in commodity prices generate a bigger contraction in total production in states with low numbers of bank accounts per person. A rise in commodity prices generates a bigger expansion of the number of formal workers as well as a wider contraction in the number of informal workers in regions with a low number of bank accounts per person

This thesis examines the impact of terms of trade shocks on commodity-exporting small, open economies. The first chapter examines whether households, firms and policymakers in these economies can distinguish between temporary and permanent commodity price shocks. I find that they are largely unable to do so. In fact, my model suggests that the expected future path of commodity prices following a temporary price shock is almost identical to the expected future path of commodity prices following a permanent price shock. However, I also find that these information frictions reduce the magnitude of business cycle fluctuations, contrary to popular belief. In the second chapter I describe optimal monetary policy in an environment where agents cannot directly observe whether commodity price shocks are temporary or permanent and where an economy's non-commodity sector features a learning-by-doing externality. I find that under optimal monetary policy the non-commodity sector contracts by more during a transitory commodity price boom under incomplete information than it does under full information, but by less during a permanent boom. I also examine the performance of simple monetary policy rules. A policy of responding strongly to deviations of home-produced goods inflation from target with a modest response to changes in the nominal exchange rate comes close to replicating the welfare outcomes of optimal policy. In contrast, an exchange rate peg generally produces large welfare losses. The third chapter, co-authored with my classmate Patricia Gomez-Gonzales, examines the consequences of changes in the volatility of commodity price shocks on commodity exporters. We first demonstrate the existence of time-varying volatility in the terms of trade of a selection of commodity-exporting small open economies. We then show empirically that increases in terms of trade volatility trigger a contraction in domestic consumption and investment and an improvement in the trade balance in these economies. Finally, we construct a theoretical model and demonstrate that it can replicate our empirical results.

This paper investigates the impact of commodity price shocks on financial sector fragility. Using a large sample of 71 commodity exporters among emerging and developing economies, it shows that negative shocks to commodity prices tend to weaken the financial sector, with larger shocks having more pronounced impacts. More specifically, negative commodity price shocks are associated with higher non-performing loans, bank costs and banking crises, while they reduce bank profits, liquidity, and provisions to nonperforming loans. These adverse effects tend to occur in countries with poor quality of governance, weak fiscal space, as well as those that do not have a sovereign wealth fund, do not implement macro-prudential policies and do not have a diversified export base. These findings are robust to a battery of robustness checks.

The increase in commodity prices that has taken place in the past decade or so has resulted in renewed interest in the debate about the macroeconomic consequences of such price increase. Previous studies tend to assume that all commodity price shocks are alike and advocate a "one size fit all" policy response by monetary authorities, either by means of contractionary monetary policy to alleviate inflationary pressures or doing nothing, since these shocks are believed to have insignificant economic impact. This dissertation analyses the impact of fluctuations in commodity prices on the South African economy. The first chapter studies the impact of shocks to prices of four commodities on monetary policy variables. Results show that shocks to different commodity prices have different effects on the monetary policy variables, hence rejecting the "one size fits all" policy response by monetary authorities, as some researchers have suggested. Chapter two investigates the sectorial effects of commodity price shocks. The Dutch Disease hypothesis suggests that a boom in the natural resource sector shrinks the manufacturing sector through crowding out and appreciation of the real exchange rate. South Africa is a major exporter of a large number of commodities. Using a structural VAR framework this chapter analyzes the impact of shocks to different commodity prices on the production and employment levels in the manufacturing and mining sectors in South Africa. The results show that the commodity price boom has had a positive impact on both sectors, hence the manufacturing sector did not experience signs of the Dutch disease. Chapter three examines the volatility transmission between commodity prices and nominal exchange rate in South Africa. This chapter uses conditional and realized volatility models to estimate volatility in exchange rate, gold, platinum, oil, palladium and silver prices and then employs Granger-causality, Impulse Response analysis, Variance Decomposition and Ordinary Least Squares to analyze the volatility transmission from the commodity prices to the nominal exchange rate. The results show that there is volatility transmission from commodity prices to the nominal exchange rate, hence knowing the volatility in commodity prices would improve investor's ability to manage risk in South Africa.

Declining commodity prices during mid-2014-2016 posed significant challenges to commodity-exporting economies. The severe terms of trade shock associated with a sharp fall in world commodity prices have raised anew questions about the viability of pegged exchange rate regimes. More recently, the COVID-19 pandemic and the measures needed to contain its spread have been associated with a significant disruption in several economic sectors, in particular, travel, tourism, and hospitality industry, adding to the downward pressure on commodity prices, a sharp fall in foreign exchange earnings, and depressed economic activity in most commodity exporters. This paper reviews country experiences with different exchange rate regimes in coping with commodity price shocks and explores the role of flexible exchange rates as a shock absorber, analyzing the macroeconomic impact of adverse term-of-trade shocks under different regimes using event study and panel vector autoregression techniques. It also analyzes, conceptually and empirically, policy and technical considerations in making exchange rate regime choices and discusses the supporting policies that should accompany a given regime choice to make that choice sustainable. It offers lessons that could be helpful to the Caribbean commodity-exporters.

This thesis presents three distinct chapters that look at different challenges faced by advanced and emerging market economies. Given the issues explored in these chapters, I contribute to several strands of economic literature. Yet, each chapter is motivated by its policy relevance and is embedded in the issues advanced and emerging market countries face. Chapter 1 explores the impact of income inequality on domestic investment in resource-rich countries. Income inequality may affect investment through different mechanisms. For instance, it could distort incentives for domestic investment; high-income inequality may discourage investment in public goods since low-income non-investors may benefit more from the returns on investment. As a result, countries with higher income inequality are expected to contribute less to their domestic investment. To investigate the relationship between income inequality and domestic investment, I use the data for 57 resource-rich countries from 1982-2015. Due to endogenous relationships among variables, I use generalized method-of moments estimators that employ lagged regressors as instruments in the estimation. Using a variety of income inequality measures, I find a negative and significant relationship between these two economic indicators: income inequality and domestic investment. This result could help resource-rich countries achieve higher growth from their resource endowments. The second chapter studies the extent to which worldwide shocks can explain country-specific inflation fluctuations. My benchmark model proxy world shocks with shocks to commodity prices. First, using a factor model of commodity prices, I extract three leading factors characterizing their co-movement. Then, I use the commodity price factors in a structural vector autoregressive model to investigate the fraction of inflation fluctuations that commodity price shocks can explain. My estimation is based on the data for 67 advanced and emerging market economies from 1970-2014. Furthermore, I examine the impact of world shocks on inflation through additional mechanisms, such as changes in the world interest rate and the global economic activity index. Compared to the previous literature, I find the increased importance of world shocks in explaining country-specific inflation fluctuations. This result can guide policymakers in setting the relevant monetary policy to control or prevent inflationary pressures in an economy. Finally, the third chapter studies whether commodity price shocks matter for estimating the output gap. First, I apply the Beveridge and Nelson decomposition method and calculate the share explained by world shocks in the variance decomposition of the output gap. In my analysis, world shocks affect the output gap through commodity price indices and global economic factors. My study includes five advanced and ten emerging market economies from 1980-2018. Then, I investigate whether commodity price shocks can improve the accuracy of this estimation. To do this, I exclude commodity price indices from my model to estimate the output gap. Finally, I use output gaps estimated with and without commodity price indices in an inflation forecasting model to compare the forecast errors of predicted inflation. Using a forecast error test, I find that the estimated output gap using commodity price indices would provide better results in forecasting inflation than other output measures.

Fluctuations in commodity prices are an important driver of business cycles in small emerging market economies (EMEs). We document how these fluctuations correlate strongly with the business cycle in EMEs. We then embed a commodity sector into a multi-country EMEs’ business cycle model where exogenous fluctuations in commodity prices follow a common dynamic factor structure and coexist with other driving forces. The estimated model assigns to commodity shocks 42 percent of the variance in income, of which a considerable part is linked to the common factor. A further amplification mechanism is a ”spillover” effect from commodity prices to risk premia.

The author estimates the effects on growth of commodity price shocks, and uncertainty within an established empirical growth model. Ex-post shocks, and ex-ante uncertainty have been treated in the empirical literature as if they were synonymous. But they are distinct concepts, and it is both theoretically, and empirically inappropriate to treat them as synonymous. He shows that the interaction between policy, and aid is robust to the inclusion of variables capturing commodity price movements. More important, his approach departs in three ways from earlier empirical studies of the subject: 1) It deals with issues of endogeneity, without incurring an excessive loss of efficiency. 2) It defines the dependent variable to allow an assessment of the longer-term implications of temporary trade shocks. 3) It imposes no priors on how commodity price movements affect growth, but compares and contrasts a range of competing shock, and uncertainty specifications. The author resolves the disagreement about the long-run effect of positive shocks on growth, finding that positive shocks have no long-run impact on growth (that windfalls from trade shocks do not translate into sustainable increases in income). He shows that negative shocks have large, highly significant, and negative effects on growth, but that commodity price uncertainty does not affect growth.

Fluctuations of commodity prices, most notably of oil, capture considerable attention and have been tied to important economic effects, such as inflation and low rates of economic growth. Commodity Prices and Markets advances our understanding of the consequences of these fluctuations, providing both general analysis and a particular focus on the countries of the Pacific Rim. The volume addresses three distinct subjects: the difficulties in forecasting commodity prices, the effects of exogenous commodity price shocks on the domestic economy, and the relationship between price shocks and monetary policy. The ability to forecast commodity prices is difficult but of great importance to businesses and governments, and this volume will be invaluable to professionals and policy makers interested in the field.
