Combinations of technology in US patents, 1926–2009: a weakening base for future innovation?

In combinatorial models of innovations, new technologies are built from combinations of pre-existing technological components. Researchers learn which components work well together by observing previously successful combinations and the pool of ideas can be ‘fished out’, i.e. exhausted, if it is not ‘restocked’ by the discovery of novel connections. We first show US patents have made increasingly less novel connections among technological constituents since the 1950s, and that the number of technological fields to which these connections are applicable has stopped growing since the 1980s. We then estimate the parameters of an ideas production function, and find parameter estimates consistent with technology fields being fished out if not continually restocked by the discovery of novel connections between technological components. We use the ideas production function to estimate the number of new patent applications induced by each patent granted between 1926 and 2001, and show this number has trended downward since the 1940s.     

The Implications of Rybczynski’s Theorem for Government Spending,Learning by Doing,and Labor Mobility

The evolution of a small open economy or region with labor mobility and dynamic scale economies in the high-tech sector is analyzed using the neoclassical 2×2-model. Government services are inputs to private production and influence specialization according to Rybczynskis theorem. This effect is reinforced by dynamic scale economies. Empirically observed differences in regional development and specialization are explained by diverging government policies and/or history-dependent factors. Despite of diverging wage rates, diversified regions and regions specialized in low-tech production may coexist with a common level of per capita incomes.     

Revisiting the finance–growth nexus: the Turkish case, 1980–2010

In Turkey, the empirical results on the link between financial development and economic growth are mixed. The existing studies do not take into account the fact that Turkey has experienced endemic political and economic instabilities over extended periods. This study aims to analyse the role of macroeconomic instability and public borrowing on the finance–growth nexus in Turkey by using time series econometric techniques over the 1980–2010 period. In doing so, we attempt to extend the existing literature by taking into account the role of macroeconomic instability as well as public borrowing. Our results reveal that there are additional – albeit indirect – channels between finance and growth via the effects of macro instability and public borrowing on financial development and economic growth. After taking into account the effects of overall instability and public borrowing, we found that growth–financial development relationship is bidirectional and permanent. In other words, in Turkish case, economic growth and financial development are jointly determined. Thus, our results shed some light on the ambiguity of the evidence on the link between financial development and economic growth for Turkey.     

Women,Real Estate,and Wealth in a Southern US County, 1780–1860

Abstract

In her 1986 book Women and the Law of Property in Early America, Marylynn Salmon concludes that the legal and economic changes experienced by early national and antebellum (pre–Civil War) United States women – which culminated in the passage of married women's property acts – were evolutionary rather than revolutionary. This paper examines changes in the economic status of women preceding the enactment of these statutes by analyzing new and valuable information: real-estate deeds and probate records in Henrico County, Virginia. Supplementing the diverse, yet limited, international and historical evidence on women's wealth holdings, this exploration of the asset accumulation of elite, free women in the southern US reveals that women's property holdings, personal and real, rose substantially over the 1780–1860 period. Thus, these results are consistent with those of other scholars, such as Marylynn Salmon, who document an increase in early national and antebellum women's economic status.     

The time structure of production in the US, 2002–2009

The US time structure of production during the 2002 through 2009 business cycle is characterized empirically using industry-level input-output data. An industry’s total industry output requirement (TIOR) is proposed as a metric for “roundaboutness”. I find that the time structure of production lengthened following the Federal Reserve’s 2002 expansionary deviation from the Taylor rule and then contracted during the Great Recession. Value added growth in the most-roundabout of US industries accelerated relative to that of the least-roundabout industries. Heading into the Great Recession, value-added growth in the most-roundabout industries contracted early and turned negative in 2007 while value-added growth in the least-roundabout industries remained positive until 2009. The stylized facts of the time structure of production are consistent with Austrian Business Cycle Theory.     

A tale of two Ginis in the US, 1921–2012

Following a methodology by Jantzen and Volpert (2012), we use IRS Adjusted Gross Income data for the US (1921–2012) to estimate two Gini indices representing inequality at the bottom and the top of the income distribution, and to calculate the overall Gini as a function of the parameters underlying the two indices. A steady increase in the overall Gini since the Second World War actually hides two different periods of distributional changes. First, the increase in inequality from the mid 1940s to the late 1970s is driven by rising inequality at the bottom of the income distribution that more than offsets a decrease in inequality at the top. The implication is that middle-income earners gained relative to high-incomes, and especially relative to low-income earners. Second, the rise in the Gini after 1981 is driven by rising inequality at the top. Third, top-driven inequality follows a U-shaped trajectory consistent with Piketty and Saez (2003, 2006). Fourth, the welfare effects of the different distributional changes behind increasing inequality can be evaluated in light of the Lorenz-dominance criterion by Atkinson (1970): we argue that the rise in inequality since 1981 is much more likely to be associated with a social welfare loss net of compensating growth.

The retreat of the state from entrepreneurial activities: A convergence analysis for OECD countries, 1980–2007

In this paper, we measure the extent and dissemination of the retreat of the state from entrepreneurial activities in 20 OECD countries during the 1980–2007 period using a three-dimensional concept and a new dataset, the REST database. We consider privatization, deregulation in network-based services, and the cutback of subsidies. Though the empirical analysis confirms a clear trend towards diminishing state influence in all three dimensions, the analysis of both sigma and conditional beta convergence indicates convergence only for privatization (measured by public employment) and for subsidization, indicating that OECD countries have become similar and have converged to a common equilibrium with respect to these dimensions.     

Regional Integration and Intra-industry Trade in Latin America, 1980–90

The decade of the 1980s saw profound changes in the political economy of Latin America. The stabilisation and debt crises forced many countries in the region to re-examine their economic policies individually as well as collectively. The consequence was both a movement in the direction of neoliberal reform that included an emphasis on export promotion as well as a revival of interest in regional integration. The specific purpose of the present paper is to examine the consequences of these changes for the structure of intra-regional trade among and between Latin American countries. More specifically, we are interested in assessing the region's performance in terms of intra-regional, intra-industry trade over the period 1980–90.     

Divorce and the Birth Control Pill in the US, 1950–85

This paper explores the relationship between the advent of the birth control pill and divorce rates. Women using the pill can decide when and whether to have children and whether to maintain their attachment to the labor force. This ability may increase women's autonomy, making divorce more feasible. The pill's effects are identified through a quasi-experiment exploiting differences in the language of the Comstock anti-obscenity statutes approved in the late 1800s and early 1900s in the United States. Empirical evidence from state-level data on US divorce rates 1950 to 1985 shows that sales bans of oral contraceptives have a negative impact on divorce. These findings are robust to alternative specifications and controls for observed (such as women's labor force participation) and unobserved state-specific factors, and time-varying factors at the state level. Results suggest that the impact of women's control of hormonal contraception on their autonomy is important in divorce decisions.     

A model of exchange rate policy: evidence for the US dollar–Greek drachma rate 1975–87

This paper represents an attempt to model movements of the exchange rate between the US dollar and Greek drachma. A stuctural model is set up, and then a reduced-form error correction(EC) speicifcation is derived. On the basis of co-integration test, the results do not support the existence of al long-run equilibrium relationship between the exchange rate and price differential. Furthermore, the instrumental variable estimation of the EC model indicates that the monetary authorities have pursued a short-run anti-inflationary exchange rate poilicy that appreciates the exchange rate in the presence of wage inflation as an attempt to mitigate the depreciating pressures on the domestic currency and thus to ease the adjustment required on Greek producers.     

Skill-Specific rather than General Education: A Reason for US–Europe Growth Differences?

In this paper, we develop a model of technology adoption and economic growth in which households optimally obtain either a concept-based, general education or a skill-specific, vocational education. General education is costly to obtain, but enables workers to operate new production technologies. Firms weigh the cost of adopting and operating new technologies against increased profits and optimally choose the level of adoption. We show that an economy whose policies favor vocational education will grow slower in equilibrium than one that favors general education. More importantly, the gap between their growth rates will increase with the growth rate of available technology. By characterizing the optimal Ramsey education policy we also demonstrate that the optimal subsidy for general education increases with the growth rate of available technology. Our theory suggests that European education policies that favored specialized, vocational education might have worked well, both in terms of growth rates and welfare, during the 1960s and 1970s when available technologies changed slowly. However, in the information age of the 1980s and 1990s when new technologies emerged at a more rapid pace, they might have contributed to an increased growth gap relative to the United States.     

The Impact of Treasury Yields on US Presidential Approval, 1960–2010

ABSTRACT

The ‘power of bond markets’ is a widely assumed and poorly understood feature of the global economy. We demonstrate that even in a bond market as stable as the United States this influence is considerable. In this article, we scrutinise a particularly direct influence, the impact of US Treasury yields on presidential approval rates. Our empirical analysis from 1961 to 2010 demonstrates that rising/falling bond yields lead to a decline/increase in approval rates. We show that this impact is mediated via the US mortgage market. The stronger the rise in mortgage rates, the stronger the influence of Treasury yields on presidential approval. We then outline the broader possible political impacts of this, particularly given foreign and domestic central bank ownership of US Treasuries.     

The Austrian income tax tariff, 1955–2006

Using official statistics and tax laws, we outline and discuss the evolution of the personal income tax in Austria since the beginning of the Second Republic in 1955. Focusing on the tax tariff and its progressivity properties, we identify a period of high (and increasing) progressivity before 1989, followed by a period of diminished progressivity since 1989. While still being a powerful revenue instrument, the Austrian income tax seems to have lost both redistributive impact and political allure.

Profit rate in the US, 1949–2007: a Markov switching assessment

The article investigates the growth in the general profit rate in the US during the 1949–2007 period with a Markov switching model. The evidence is consistent with a long swing with means displaying opposite signs under the two regimes (increasing or declining) and high degree of persistence within each regime. The results for this nonlinear approach reinforce previous empirical evidence that does not provide support for a systematic and declining tendency in profit rate as advanced in the Marxian literature.     

The United States and United Kingdom activities of Japanese banks, 1980–1988

This paper analyzes the United States and United Kingdom activities of Japanese banks by integrating their activities in these two markets with the regulatory environment for banks in Japan and Japan's overall external financial position, as well as with business opportunities in the two host countries. The paper concludes that the regulatory environment in Japan, including restraints on interest rates and possible quantitative restraints, has had an impact on activities of Japanese banks in these two foreign markets.Japanese banks appear to have adjusted to their domestic regulatory environment by using their London branches as a flexible funding source and their U.S. offices in extending commercial and industrial loans to Japan-based companies as well as a substitute location for interbank trading. In both markets Japanese banking offices are large net barrowers from unrelated banks because of constraints on raising funds in their homer market.     

Persistence,mean reversion and non-linearities in the US housing prices over 1830–2013

The objective of this study is to provide a direct estimate of the degree of persistence of measures of nominal and real house prices for the US economy, covering the longest possible annual sample of data, namely 1830–2013. The estimation of the degree of persistence accommodates for non-linear (deterministic) trends using Chebyshev polynomials in time. In general, the results show a high degree of persistence in the series along with a component of non-linear behaviour. In general, if we assume uncorrelated errors, non-linearities are observed in both nominal and real prices, but this hypothesis is rejected in favour of linear models for the log-transformation of the data. However, if autocorrelated errors are permitted, non-linearities are observed in all cases, and mean reversion is found in the case of logged prices, though given the wide confidence intervals, the unit root null hypothesis cannot be rejected in these cases.     

Real exchange rate shocks on tradables,nontradables, and the current account: Mexico, 1980–2000.

Effects of external and income shocks on consumption and on the current account in Mexico from 1980 to 2000 are investigated. An intertemporal model captures the extent into which non-traded goods consumption affects traded-goods consumption, clarifying the roles of intratemporal or intertemporal substitution. Vector autoregressions (VARs) show that the 1% shock to non-traded goods consumption affects traded-goods consumption by −2% immediately, reverting to zero only after one year, supporting the intratemporal channel. Real exchange rate (RER) shocks exert considerable macroeconomic fluctuations. The 1% shock to RER affects traded goods consumption by −2% immediately, reaching −5% one year later. At the expense of income shocks, RER shocks grow in explanatory power over time: from 20%–25% at 1 quarter to 65%–69% of the variance of traded goods consumption 3 years later. Figures for the current account range from 14% to 68%, while income shocks appear less important. In contrast, for non-traded goods, RER shocks roughly match the quantitative importance of income shocks, reinforcing the theoretical analysis.

China–US economic and trade relations,trade news,and short-term fluctuation of the RMB exchange rate

The trade war between the US and China affects the fluctuation of RMB exchange rate. We collect news on China–US trade policies and talks from January 2017 to July 2020. Results show that China–US dialogue and tariff imposition have the greatest impact on the percentage of RMB appreciation and depreciation. Additionally, tariff relaxation and increasing enterprise restrictions can cause a sharp appreciation and depreciation. “Policies” events and trade news from the US influence RMB fluctuations the most significantly. Finally, positive events cannot significantly cause RMB appreciation, but negative events can significantly cause RMB devaluation.
