THE IMPACT OF MERGERS IN U.S. PETROLEUM INDUSTRY ON WHOLESALE GASOLINE PRICES

Starting in the mid‐1990s, the U.S. petroleum industry experienced a wave of mergers, several of them between large petroleum companies that were previously competitors. Using an econometric analysis of terminal city‐specific data, this study finds that the majority of the mergers led to higher wholesale gasoline prices in the United States in the mid‐1990s through 2000.

WHAT HAS BEEN HAPPENING TO AGGREGATE CONCENTRATION IN THE U.S. ECONOMY IN THE TWENTY‐FIRST CENTURY?

This paper extends earlier data series on aggregate concentration in the U.S. economy—the percentage of aggregate economic activity that could be attributed to the largest “X” companies—into the first two decades of the twenty‐first century. We find that there has been a moderate but continued increase in aggregate concentration since the mid‐1990s. This increase appears in data on employment and payrolls that have been compiled by the U.S. Bureau of the Census, as well as employment and profits data that are drawn from the annual “Fortune 500” lists. This increase does not, however, appear to have raised aggregate concentration above the levels of the early 1980s. (JEL L10, L11, L19)     

Understanding the U.S.-China Trade War

ABSTRACT

Three major concerns drove the U.S. into initiating the trade war, and they are (a) the concern that China’s chronically large trade surplus was depressing job creation in the U.S. (b) the concern that China was using illegal and unfair methods to acquire U.S. technology at an effectively discounted price; and (c) the concern that China seeks to weaken U.S. national security and its international standing. On the dispute over China’s exchange rate and trade imbalance, the first conclusion is that it was marked by analytical confusion over the meaning of the term ‘equilibrium exchange rate’. The second conclusion is that China’s trade imbalance reflects the economic conditions in both China and U.S., and that the efficient and fair solution of the problem requires policy changes in both countries. On the industrial policy dispute, the first conclusion is that the issue of forced technology transfer is largely a dispute about China using its market power to benefit itself at the expense of its trade partners. The second conclusion is that China’s use of market power can last only until the other large countries could unite and retaliate as a group. The inevitability of retaliation means that China should replace the joint-venture (JV) mechanism for technological diffusion with other ways to strengthen its technological capability. On the U.S. concern about whether China trade weakens its national security, the first conclusion is that the notion of national security that is commonly adopted in the U.S. trade policy debate is ignorant about the primary determinants of U.S. capability in innovation. By focusing instead mainly on how to hold down China technologically, the long-run outcome will be a technologically weaker U.S. and hence, a more vulnerable U.S. The second conclusion is that the U.S. must identify a clear, short list of critical technologies and critical infrastructure for the recently reformed Committee for Foreign Investment in the United States (CFIUS) to cover, and update this list constantly. Otherwise, the broad and changing nature of notions about national security would allow the bureaucratically driven phenomenon of mission-creep to steadily expand the coverage of the CFIUS process, thereby steadily rendering CFIUS to be operationally capricious. Our principal policy suggestion to China is that, because China’s economy in 2018 is very different from that in 1978 (e.g. many parts of China now look like Singapore and China is Africa’s biggest donor), there should be more reciprocity in China’s trade and investment relations with the advanced economies despite China’s status as a developing economy under WTO rules. Our principal policy suggestion to President Trump is to stop equating strategic competition with economic competition. Strategic competition is normally a zero-sum game. While fair economic competition is usually a zero-sum game in the short run, it generally creates a win-win outcome in the long run.

DOUBLING U.S. EXPORTS UNDER THE PRESIDENT'S NATIONAL EXPORT INITIATIVE: IMPLICATIONS OF SUCCESSFUL IMPLEMENTATION

President Obama's National Export Initiative (NEI) is targeted at doubling U.S. exports between 2010 and 2015. We apply USAGE to quantify what the NEI would need to do to foreign import‐demand curves and domestic export‐supply curves to achieve this target. USAGE is a dynamic economy‐wide model of the U.S. incorporating recession‐relevant factor market specifications including excess capacity and wage/labor‐demand elasticities that vary with the level of employment. In our central simulation, export‐promotion policies compatible with the President's target reduce the cost of the current recession from about 70 million 1‐year jobs for the period 2008–2020 to 45 million jobs.

ANALYSIS OF COMPETITION IN THE DEFENSE INDUSTRIAL BASE: AN F‐22 CASE STUDY

Consolidation of the defense industrial base has led to concerns about whether enough competition exists between remaining firms to maintain needed cost reduction and innovation. We examine competition in the U.S. defense industrial base by performing an in‐depth case study of Lockheed Martin and the F‐22 program that considers multiple tiers of the industrial base. We find that defense firm specialization has led to outsourcing practices and arguably a more robust U.S. defense industrial base. Implications for government policy are identified.

ECONOMY‐WIDE EFFECTS OF REDUCING ILLEGAL IMMIGRANTS IN U.S. EMPLOYMENT

We use an economy‐wide model to analyze the effects of three broad programs to reduce illegal immigrants in U.S. employment: tighter border security; taxes on employers; and vigorous prosecution of employers. After looking at macroeconomic industry and occupational effects, we decompose the welfare effect for legal residents into six parts covering changes in: producer surplus and illegal wage rates; skilled employment opportunities for natives; aggregate capital; aggregate legal employment; the terms of trade; and public expenditure. The type of program matters. Our analysis suggests a prima facie case in favor of taxes on employers. (JEL J61, C68)     

On the Growth and Welfare Effects of Defense R&D

In the United States, defense R&D share of GDP has decreased significantly since 1960. To analyze the implications on growth and welfare, we develop an R&D‐based growth model that features the commonly discussed crowding‐out and spillover effects of defense R&D on civilian R&D. The model also captures the effects of defense technology on (a) national security resembling consumption‐type public goods and (b) aggregate productivity via the spin‐off effect resembling productive public goods. In this framework, economic growth is driven by market‐based civilian R&D as in standard R&D‐based growth models and government‐financed public goods (i.e., defense R&D) as in Barro (1990). We find that defense R&D has an inverted‐U effect on growth, and the growth‐maximizing level of defense R&D is increasing in the spillover and spin‐off effects. As for the welfare‐maximizing level of defense R&D, it is increasing in the security‐enhancing effect of defense technology, and there exists a critical degree of this security‐enhancing effect below (above) which the welfare‐maximizing level is below (above) the growth‐maximizing level.     

Investment-Specific Technical Change in the United States (1947–2000): Measurement and Macroeconomic Consequences

By extrapolating Gordon's measures of the quality bias in the official price indexes, we construct quality-adjusted price indexes for 24 types of equipment and software (E&S) from 1947 to 2000 and use them to measure technical change at the aggregate and at the industry level. Technological improvement in E&S accounts for an important fraction of postwar GDP growth and plays a key role in the productivity resurgence of the 1990s. Driving this finding is 4% annual growth in the quality of E&S in the postwar period and more than 6% annual growth in the 1990s. The acceleration in the 1990s occurred in every industry, consistent with the idea that information technology represents a general-purpose technology. Furthermore, we measure for the aggregate economy and different sectors the “technological gap”: how much more productive new machines are compared to the average machine. We show that the technological gap explains the dynamics of investment in new technologies and the returns to human capital, consistent with the Nelson–Phelps conjecture. Since the technological gap continues to increase—it more than doubled in the past 20 years—our evidence supports the view that at least some of the recent increase in productivity growth is sustainable.

WHAT IT TAKES TO SOLVE THE U.S. GOVERNMENT DEFICIT PROBLEM

This paper uses a structural multi‐country macroeconometric model to estimate the size of the decrease in transfer payments (or tax expenditures) needed to stabilize the U.S. government debt/gross domestic product (GDP) ratio. It takes into account endogenous effects of changes in fiscal policy on the economy and in turn the effect of changes in the economy on the deficit. A base run is first obtained for the 2013:1–2022:4 period in which there are no major changes in U.S. fiscal policy. This results in an ever increasing debt/GDP ratio. Then transfer payments are decreased by an amount sufficient to stabilize the long‐run debt/GDP ratio. The results show that transfer payments need to be decreased by 2% of GDP from the base run, which over the 10 years is $3.2 trillion in 2005 dollars and $4.8 trillion in current dollars. The real output loss is 1.1% of baseline GDP. Monetary policy helps keep the loss down, but it is not powerful enough in the model to eliminate all of the loss. The estimates are robust to a base run with less inflation and to one with less expansion. (JEL E17)     

BANK EFFICIENCY AND THE EFFECTIVENESS OF MONETARY POLICY

Advances in information technology and bank consolidation have altered the way banks operate by necessitating that banks control costs and provide services efficiently to remain competitive. Given the unique role bank operations play in the transmission of monetary policy, a key unresolved question is whether bank efficiency alters monetary policy outcomes. Using a stochastic frontier approach to measure cost‐efficiency and panel data of U.S. bank balance sheets, we show that banks with greater cost‐efficiency are more sensitive to monetary shocks.

INTERNATIONAL COMPETITION AND U.S. R&D SUBSIDIES: A QUANTITATIVE WELFARE ANALYSIS*

In the early 1970s U.S. firms were the uncontested world leaders in R&D investment in most manufacturing sectors. Later, led by Japan and Europe, foreign firms began to challenge American R&D leadership in many sectors of the economy. This period of increasing technological competition is contemporaneous with a substantial increase in U.S. R&D subsidies. What is the effect of the observed increase in international competition on U.S. welfare? How does foreign competition affect the optimal R&D subsidy in the United States, and, consequently, how far is this from the subsidy observed in the data? This article addresses these questions in a two‐country quality ladder growth model.     

THE TRANSMISSION OF MONETARY POLICY IN A MULTISECTOR ECONOMY*

This article constructs and estimates a sticky‐price, Dynamic Stochastic General Equilibrium model with heterogeneous production sectors. Firms in different sectors vary in their price rigidity, production technology, and the combination of material and investment inputs. In particular, firms buy inputs from all sectors using the actual Input–Output Matrix and Capital Flow Table of the U.S. economy. By relaxing the standard assumption of symmetry, this model allows idiosyncratic sectoral dynamics in response to monetary policy shocks. The model is estimated by the Generalized Method of Moments using sectoral and aggregate U.S. time series.     

THE IMPACT OF OIL PRICE SHOCKS ON THE U.S. STOCK MARKET*

It is shown that the reaction of U.S. real stock returns to an oil price shock differs greatly depending on whether the change in the price of oil is driven by demand or supply shocks in the oil market. The demand and supply shocks driving the global crude oil market jointly account for 22% of the long‐run variation in U.S. real stock returns. The responses of industry‐specific U.S. stock returns to demand and supply shocks in the crude oil market are consistent with accounts of the transmission of oil price shocks that emphasize the reduction in domestic final demand.     

THE BEHAVIOR OF U.S. PUBLIC DEBT AND DEFICITS DURING THE GLOBAL FINANCIAL CRISIS

In this paper we test the sustainability of U.S. public debt for the period 1916–2012 by analyzing how the primary surplus to gross domestic product (GDP) responds to changes in the debt to GDP ratio in a time‐varying parameter model. Further, we determine the stationarity property of the debt/GDP ratio while accommodating possible breaks in the data caused by wars and economic crisis under both the null and alternative hypotheses of an endogenous unit root test. The results show that the U.S. public debt was sustainable until 2005 when the primary surplus to GDP reacted negatively to the debt/income ratio. This is further exacerbated during the global financial crisis when primary surpluses continued to fall with increased debt, thus jeopardizing the sustainability of fiscal policy. While the stationarity test shows that the U.S. fiscal debt/GDP ratio is sustainable, it fails to highlight the risk that its debt policy has been becoming unsustainable in recent years.

FOREIGN ENTRY INTO U.S. SERVICE INDUSTRY BY TAKEOVERS AND THE CREATION OF NEW FIRMS

We study the relation between foreign entry in U.S. service sector industries and the revealed comparative advantage of the investing country using U.S. Bureau of Economic Analysis firm‐level data on all foreign takeovers and new foreign‐owned firms from 1998 to 2008. We find foreign acquisitions in the service sector are in industries of U.S. comparative advantage while new foreign firms are in industries of investing country's comparative advantage. This suggests that foreign acquisitions in the service sector are not directly related to foreign investors' competitiveness in the industry of investment. In contrast foreign investors in new service sector firms come from countries with a competitive edge in the industries of investment. We also find that foreign investors of new service sector firms are from Organization for Economic Co‐operation and Development (OECD) countries with a comparative disadvantage in royalties and trademarks.

How Big Was the Effect of Budget Consolidation on the Australian Economy in the 1990s?

This article evaluates the effects of budget consolidation on the Australian economy in the 1990s. As the economy recovered from the 1991–92 recession, the need to improve the fiscal balance to lift national saving became the dominant influence on fiscal policy. The article argues that spending cuts by the Australian federal government announced in 1996 had immediate effects on financial markets, with reduced long‐term interest rates of about 50 basis points in 1996–97. Using a modified version of the Treasury macroeconometric model of the Australian economy (TRYM), the article simulates the net macroeconomic effects of the expenditure cuts, fiscal consolidation and lower long‐term interest rates. The article finds that the program of budget consolidation had a sizeable short‐ and medium‐term impact on the economy, raising Gross Domestic Product by up to three‐quarters of a percentage point and reducing unemployment by 0.3 percentage points over the next two to three years.     

The implications of heterogeneous resource intensities on technical change and growth

Abstract We analyze the long‐term dynamics of an economy in which sectors are heterogeneous with respect to the intensity of natural resource use. It is shown that heterogeneity induces technical change to be biased towards resource‐intensive sectors. Along the balanced growth path, the sectoral structure of the economy is constant as the higher resource dependency in resource‐intensive sectors is compensated by enhanced research activities. Resource taxes have no impact on dynamics except when the tax rate varies over time. Research subsidies and the sectoral provision of productivity‐enhancing public goods raise growth and provide an effective tool for structural policy.     

Measuring persistence of U.S. city prices: new evidence from robust tests

This article revisits the empirical analysis in Cecchetti et al. (Int Econ Rev 43:1081–1099, 2002) involving long-span U.S. city prices, who estimated the persistence of U.S. price differentials to be around 9 years. After controlling for the structural breaks in the data, we find that U.S. city price level differentials are I(0) stationary processes with the median half-life of convergence ranged between 1.5 and 2.6 years, estimates that are in accordance with what should be expected from a highly integrated economy as the United States. Our results are also robust to a pairwise test of price level convergence.
