Toward a Better Understanding of Macroeconomic Interdependence
The concept of a representative foreign economy has no proper justification in the literature, and the consequences of aggregating the rest of the world into one representative economy are not fully understood.
Identifying Global and National Output and Fiscal Policy Shocks Using a GVAR
The paper contributes to the growing Global VAR (GVAR) literature by showing how global and national shocks can be identified within a GVAR framework. The usefulness of the proposed approach is illustrated in an application to the analysis of the interactions between public debt and real output growth in a multi-country setting, and the results are compared to those obtained from standard single-country VAR analysis. We find that on average (across countries) global shocks explain about one-third of the long-horizon forecast error variance of output growth, and about one-fifth of the long-run ...
Early Mandated Social Distancing Does Best to Control COVID–19 Spread
Voluntary social distancing and a lack of compliance with mandated polices have led to unnecessarily high infection rates and death tolls in a number of countries.
Consuming price differences persist among eight Texas cities
The differences in what consumers pay for a given product in eight Texas cities increased considerably in the 2000s?Dallas being by far the most expensive city in the sample. A strong price adjustment mechanism, however, ensures that the relative price between any two Texas locations tended to rapidly revert to its mean value
A simple model of price dispersion
This article considers a simple stock-flow matching model with fully informed market participants. Unlike in the standard matching literature, prices are assumed to be set ex-ante. When sellers pre-commit themselves to sell their products at an advertised price, the unique equilibrium is characterized by price dispersion due to the idiosyncratic match payoffs (in a marketplace with full information). This provides new insights into the price dispersion literature, where price dispersion is commonly assumed to be generated by a costly search of uninformed buyers.
The perils of aggregating foreign variables in panel data models
The curse of dimensionality refers to the difficulty of including all relevant variables in empirical applications due to the lack of sufficient degrees of freedom. A common solution to alleviate the problem in the context of open economy models is to aggregate foreign variables by constructing trade-weighted cross-sectional averages. This paper provides two key contributions in the context of static panel data models. The first is to show under what conditions the aggregation of foreign variables (AFV) leads to consistent estimates (as the time dimension T is fixed and the cross section ...
Geographic Inequality of Economic Well-being among U.S. Cities: Evidence from Micro Panel Data
We analyze the geographic inequality of economic well-being among U.S. cities by utilizing a novel measure of quantity based product-level economic well-being, i.e., the number of goods and services that can be purchased by consumers with an average city wage. We find a considerable cross-city dispersion in the economic well-being and the geographic dispersion has been on the steady rise since the mid-1990s for most goods and services under study. Strong geographic correlations exist in the local economic well-being and our empirical analysis based on a Global VAR (GVAR) model suggests that ...
How have global shocks impacted the real effective exchange rates of individual Euro area countries since the Euro's creation?
This paper uncovers the response pattern to global shocks of euro area countries' real effective exchange rates before and after the start of Economic and Monetary Union (EMU), a largely open ended question when the euro was created. We apply to that end a newly developed methodology based on high dimensional VAR theory. This approach features a dominant unit to a large set of over 60 countries' real effective exchange rates and is based on the comparison of two estimated systems: one before and one after EMU. ; We find strong evidence that the pattern of responses depends crucially on the ...
Impact of Chinese slowdown on U.S. no longer negligible
The impact of the Chinese economy on the U.S. has notably increased over the past two decades. Econometric modeling shows that the U.S. economy is more likely to directly and indirectly (through its trading partners) feel the impact of a negative shock to Chinese output.
Rising Public Debt to GDP Can Harm Economic Growth
The debt?growth relationship is complex, varying across countries and affected by global factors. While there is no simple universal threshold above which debt to GDP significantly depresses growth, high and rising public debt burdens slow growth in the long term, data from the past four decades indicate.
