COVID-19 and emerging markets: A SIR model, demand shocks and capital flows

We quantify the macroeconomic effects of COVID-19 for a small open economy. We use a two-country framework combined with a sectoral SIR model to estimate the effects of collapses in foreign demand and supply. The small open economy (country one) suffers from domestic demand and supply shocks due to its own pandemic. In addition, there are external shocks coming from the rest of the world (country two). Aggregate exports of the small open economy decline when foreign demand goes down, and aggregate imports suffer from lockdowns in the rest of the world. We calibrate the model to Turkey. Our results show that the optimal policy, which yields the lowest output loss and saves the maximum number of lives, for the small open economy, is an early and globally coordinated full lockdown of 39 days.

More than just supply and demand: Macroeconomic shock decomposition in Croatia during and after the transition period

This paper separates macroeconomic shocks into external and domestic aggregate demand and supply shocks in Croatia during and after the transition period using a Bayesian SVAR model. The standard decomposition into aggregate demand and supply shocks covers important information on external sources of economic fluctuations. We find that domestic shocks were a dominant source of fluctuations during the transition period from 1992 to 2000. External shocks increased their importance after 2000, becoming the dominant source of fluctuations with the Global financial crisis. International comparison with other EU post-transition countries shows that short run GDP fluctuations are best explained by domestic aggregate supply shocks in 9 out of 11 analyzed countries, including Croatia. However, in the medium run, GDP fluctuations are dominantly explained by external aggregate demand shocks in 8 out of 11 countries, including Croatia. Inflation in Croatia is driven by external shocks both in the short- and medium run.

The dynamic effects of fiscal policy and fiscal multipliers in Tunisia

ABSTRACT This study analyses the macroeconomic effects of fiscal policy by estimating fiscal multipliers for Tunisia. The study is based on the Structural Vector Autoregression (SVAR) model and uses quarterly data from 2000Q1 to 2019Q4. Five main insights can be drawn from these results. First, fiscal multipliers are moderate, as suggested by earlier studies. Second, spending multipliers generated by total and consumption expenditures, respectively, are small, implying that government spending generates substantial crowding out effects. Third, investment multipliers are larger than consumption multipliers. Fourth, fiscal multipliers have declined in the post-2011 revolution period, suggesting that spending multipliers are lower during times of recession. Fifth, domestic supply shocks could shape the effects of fiscal policy and cause spending multipliers to fall.

The Time-Varying Effects of Oil Shocks on the Trade Balance of Saudi Arabia

This study aims to analyze the impact of oil shocks on the external balance of Saudi Arabia, as one of the largest net oil-exporting countries. To this end, a time-varying parameter vector autoregression model (TVP-VAR) is estimated by using quarterly data covering the period between 1991: Q1 and 2021: Q4. We find that identifying the source of shocks plays an important role in understanding the time-varying impact of shocks on its economy. Our findings indicate that the global oil production shocks excluding Saudi Arabia have a negative and significant impact on the trade balance and are greater than the impact of the Saudi oil production shocks, which is not significant for most of the period. In addition, we found that oil price shocks have more profound and much greater impacts than global and domestic oil supply shocks. This may be attributed to the fact that oil price shocks are more than oil supply shocks, and supply shocks are linked to oil price shocks. However, impulse responses show that the effects of oil shocks are volatile over time and their effects are generally more pronounced during and immediately after global shocks. Our findings have serious implications for the trade balance of Saudi Arabia, particularly in the low and volatile oil price environment.

Global markets and the commons: the role of imports in the US wild-caught shrimp market

The commons literature focuses heavily on rules and the behavior of resource users but places less emphasis on the returns to individual effort. However, for most resource settings, market conditions and associated resource prices are key drivers of exploitation effort. In a globalized world, import competition can strongly influence the incentives for individual resource users, a topic largely unexplored in the commons literature. Import competition is especially salient for seafood, one of the most internationally traded food groups. We analyze the US shrimp market, which was once dominated by domestic catches but is now mostly supplied by imports. For domestic producers (users of the commons), lower revenues result, while US consumers eat more shrimp at lower prices. Globalization changed the sources of price risk and compensation that domestic producers face and altered incentives to exploit the commons. In a market dominated by domestic supply shocks, the price response to a shock moderates the effect on revenue and effort. In a market dominated by imports, domestic shocks are buffered by import adjustments, while price movements are determined by global shocks. Despite losses for the domestic fishery, globalization creates new incentives to coordinate effort and capture price premiums determined in the global market.

The impact of COVID-19 on European global value chains: Some concerns about diversification and resilience

The disruptions and supply problems caused by the COVID-19 pandemic in the European Union (EU) have raised several issues concerning the EU’s participation in Global Value Chains (GVC). One of the most discussed points in the current debate is the need to increase economic and productive resilience. This paper describes the participation of the EU in GVC and the possibilities of geographical and productive diversification by analyzing the European export basket similarity with China and the relative technological advantages. Furthermore, building up on previous works, we propose a regression equation which allows us to analyze formally the impact of the pandemic on EU exports, and to examine the individual contributions of the domestic supply, international demand, and GVC disruptions shocks. Our findings suggest that the new member countries that joined the EU in 2004, have a more similar export basket with China. Also, we find that the fall in EU exports was mainly due to the international demand shock and the GVC disruption shock; while the EU dependence on the GVC networks is confirmed, disruptive effects are less severe for more technologically sophisticated products.

The US current account, sustainability, and the international monetary system

In this paper, we examine the sources of the US current account imbalances and discuss the role of the international monetary system in enabling the US in carrying such external deficits. There is evidence that the stochastic properties of the US current account are not compatible with the intertemporal national budget constraint. We argue that this is likely to be related to the dominant role of the U.S. dollar as an international reserve asset, which allows the US to meet international demand for safe assets and allows borrowing at very low interest rates. Results from a structural VAR model indicate that temporary shocks dominate the current account in the short run, whereas domestic permanent supply shocks and preference shocks contribute significantly to US current account movements in the long run. To the extent that temporary shocks stem from aggregate demand, stabilizing aggregate demand is important in achieving long-term sustainability in the current account. Finally, the paper discusses the role of the international financial system and the international role of the U.S. dollar in contributing to US external imbalances.

Labour mobility as an adjustment mechanism to asymmetric shocks in Europe: evidence from the Czech Republic, Hungary, Poland and Slovakia

This paper assesses the nature and correlation of shocks in Visegrad countries and investigates the role of labour mobility in the process of adjustment to the effects of asymmetric shocks. Structural vector autoregression (SVAR) models are employed to assess the nature and correlation of shocks while dynamic cointegrated panel autoregressive distributed lag (ARDL) models are used to determine the role of labour mobility in the adjustment process. The dataset for the SVAR models is quarterly time series and covers the period 2000–2020. The dataset for the cointegrated panel ARDL models is annual and covers the period 2000–2019. The results show more asymmetries in external supply, domestic supply, demand and monetary shocks before the financial crisis. The findings also show that more symmetries occurred in Visegrad countries after the financial crisis in relation to external and domestic supply shocks. Asymmetries persisted with regard to demand and monetary shocks after the financial crisis. With labour mobility as an adjustment mechanism to asymmetric shocks, the paper finds that the capacity of labour mobility is very low. The percentage of net migration in the total population is less than 1% in the four countries compared to 15% in the United States. The size of the adjustment coefficients shows that it takes 3–5 years for countries to adjust to asymmetric shocks through labour mobility.

Global inflation dynamics and inflation expectations

In this paper we investigate dynamics of inflation and short-run inflation expectations. We estimate a global vector autoregressive (GVAR) model using Bayesian techniques. We then explore the effects of three source of inflationary pressure that could drive up inflation expectations: domestic aggregate demand and supply shocks as well as a global increase in oil price inflation. Our results indicate that inflation expectations tend to increase as inflation accelerates. However, the effects of the demand and supply shocks are short-lived for most countries. When global oil price inflation accelerates, however, effects on inflation and expectations are often more pronounced and long-lasting. Hence, an assessment of the link between observed inflation and inflation expectations requires disentangling the underlying sources of inflationary pressure. We also examine whether the relationship between actual inflation and inflation expectations changed following the global financial crisis. The transmission between inflation and inflation expectations is found to be largely unaffected in response to domestic demand and supply shocks, while effects of an oil price shock on inflation expectations are smaller post-crisis.

Immigration and the macroeconomy: Some new empirical evidence

We propose a new SVAR identification scheme that enables us to disentangle immigration shocks from other macroeconomic shocks in a sign-restricted model estimated on Norwegian data over the period 1990Q1 - 2014Q2. Notably, immigration is an endogenous variable in the model and can respond to the state of the economy. We find that domestic labor supply shocks and immigration shocks are well identified and are the dominant drivers of immigration dynamics. An exogenous immigration shock lowers unemployment (even among native workers), has a small positive effect on prices and on public finances, no impact on house prices and household credit, and a negative effect on productivity driven by a large decline in capital intensity.

Our results indicate that inflation expectations tend to increase as inflation accelerates. However, the effects of the demand and supply shock are for most countries only short-lived. If domestic inflation accelerates due to a global acceleration of oil price inflation, however, effects are generally more pronounced and long-lasting. This implies that to assess the link between actual inflation and inflation expectations appropriately, it is important to disentangle the underlying sources of inflationary pressure. We also examine whether the relationship between actual inflation and inflation expectations has changed since the global financial crisis. We find that the transmission between inflation and inflation expectations was largely unaffected in response to domestic demand and supply shocks, while effects of an oil price shock on inflation expectations are smaller post-crisis.

On the drivers of inflation in Sub-Saharan Africa

The perception that inflation dynamics in Sub-Saharan Africa (SSA) are driven by supply shocks implies a limited role for monetary policy in influencing inflation in the short run. SSA's rapid growth, its integration with the global economy, changes in the policy frameworks, among others, in the last decade suggest that the drivers of inflation may have changed. We quantitatively analyse inflation dynamics in SSA using a Global VAR model, which incorporates linkages among economies, as well as the role of regional and global demand and inflationary spillovers. We find that in the past 25 years, the main drivers of inflation have been domestic supply shocks and shocks to the exchange rate and monetary variables; but that, in recent years, the contribution of these shocks to inflation has fallen. Domestic demand pressures as well as global shocks, and particularly shocks to output, however, have played a larger role in driving inflation over the last decade. This implies a greater role of monetary policy as some SSA countries modernize their monetary policy frameworks.

Agricultural Value Chain Development and Regional Integration Processes

Domestic and international supply and demand shocks are an important driver of NRP fluctuations through their impacts on relative border or domestic prices. The East African Community (EAC) is a regional intergovernmental organization, formed in 2000 between Kenya, Tanzania and Uganda, and today consisting of the founding members together with Burundi, Rwanda and South Sudan. Since 2010 cooperation has consisted of a common market and a customs union, with duty-free intra-regional trade and a...

Immigration and the Macroeconomy: Some New Empirical Evidence

We propose a new VAR identification scheme that enables us to disentangle immigration shocks from other macroeconomic shocks. Identification is achieved by imposing sign restrictions on Norwegian data over the period 1990Q1 - 2014Q2. The availability of a quarterly series for net immigration is crucial to achieving identification. Notably, immigration is an endogenous variable in the model and can respond to the state of the economy. We find that domestic labor supply shocks and immigration shocks are well identified and are the dominant drivers of immigration dynamics. An exogenous immigration shock lowers unemployment (even among native workers), has a positive effect on prices and on public finances in the medium run, no impact on house prices and household credit, and a negative effect on productivity.

International Trade and Risk Sharing in the Global Rice Market: The Impact of Foreign and Domestic Supply Shocks

In the first decade of this millennium, rising food prices returned as a concern for policy makers, especially in developing economies. This paper examines how supply shocks, both domestic and foreign, impacted imports and consumption in the world rice market between 1960 and 2010. Such an investigation is important in assessing the role of trade in compensating for domestic shocks. If shortages lead economies to impose trade restrictions, then trade may not be allowed to play an important role in stabilizing consumption. The existing literature has highlighted the importance of these policy shocks in the world rice market and how they have worked to increase the volatility of prices and trade flows. Although trade cannot be expected to play a strong role when the major producing and consuming economies are simultaneously hit by negative yield shocks, such a scenario has occurred in only about 3% of all observed cases. We also find that consumption fails to stabilize even when domestic shocks are negative and foreign shocks are positive; however, imports do peak. Thus, while trade does help in coping with domestic risks, it is unable to achieve full risk sharing. Therefore, no matter the nature of foreign shocks, the principal concern is to stabilize consumption when an economy is hit by negative domestic yield shocks. The frequency of such shocks is about 12% in all observed cases, highlighting the importance of domestic responses. We find that domestic rice stocks have been important in stabilizing consumption. The reliance on domestic policies has, in turn, kept the rice market thin.

Impending Recession and How to Fight It

This article considers the problem of autonomous recession as a drop in output not directly associated with the world economic situation, but mainly due to domestic supply and/or demand shocks. To determine possible factors of autonomous recession, we have studied the stylized facts and other characteristics of such periods in countries of the Organization for Economic Cooperation and Development in 2000–12, drawing analogies with the current Russian situation, from the standpoint of both causes of a potential recession and the response of the economic authorities, that is, a countercyclical economic policy. The latter considers global and Russian experience in determining the so-called output gap (the difference between potential and actual output), mainly using modeling approaches for Russia with “nonaccelerating inflation rate of production utilization factors.” Designs of an anticrisis policy are suggested with regard to autonomous recession, the utilization of productive potential, and the characteristic features of the Russian economy as mainly resource-based and thus unusually procyclical from the point of view of macroeconomic indicators.

SSA’s rapid growth, its integration with the global economy, changes in the policy frameworks, among others, in the last decade suggest that the drivers of inflation may have changed.

Domestic demand pressures as well as global shocks, and particularly shocks to output, however, have played a larger role in driving inflation over the last decade. We also show that country characteristics matter—the extent of oil and food imports, vulnerability to weather shocks, economic importance of agriculture, trade openness and policy regime, among others, help in explaining the role of shocks.

Dynamics of Business Cycles in Vietnam: A Comparison with Indonesia and Philippines

The objective of this paper is to analyze the dynamics of business cycle features and investigate the main source of macroeconomic fluctuations in Vietnam, and then make comparison to Indonesia and the Philippines. In the first task, the business cycle features are evaluated by properties of data, including volatility, persistence and co-movement after taking Hodrick-Prescott (HP) filter in 2 periods: before and after the global financial crisis in 2008. Results indicate that these properties mostly concentrate on second period (2008-2013) in Vietnam, whereas the Asian Financial Crisis leads to a high volatility and persistence in Philippines and Indonesia. In order to identify the sources of macroeconomic fluctuations, the study adopts the Structural Vector Autoregression (SVAR) with data covered from 1996 to 2013. The evidence for countries suggests that (i) the main source of output variance is domestic supply shocks but there is a significant decrease in long-run; (ii) The fluctuations of trade balance are mostly due to external shocks, especially term of trade shocks in Vietnam, as opposed to Philippines and Indonesia where IS shocks play an important role; (iii) The fluctuations of real exchange rate are mainly driven by the domestic shocks but internal causes of each country are different; (iv) the most two important sources of price’s movements are domestic shocks, especially IS and nominal shocks in Vietnam.
