Innovation and imitation: substitutes or complements?

Most of the research on imitation and innovation has focused on developed countries and examined whether imitation promotes or hinders innovation at the macro, industry and intra firm level, and the effect that this has on economic growth. Less research has been conducted about the dynamics that exist between innovation and imitation at the plant-level in developing countries, and the effect that trade policy has on this relationship. This article uses plant-level data from Mexico to analyse the dynamic relationship that exists between innovation and imitation at the microeconomic level. The empirical results suggest that in the context of a developing country, innovation and imitation complement each other and trade policy has no effect on this relationship.     

Robots and humans – complements or substitutes?

The effect of the spread of Artificial Intelligence (AI) on wages depends on both the form of aggregate production relationships and the elasticity of substitution between human and robotic labor. With a conventional production function involving labor, robots, and ordinary capital, an increase in robotic labor can have either a positive or a negative effect on wages. Alternatively, it is possible to estimate the aggregate production relationship without measuring capital or other fixed factors explicitly, using the procedure developed by Houthakker in the 1950s. Houthakker's method is based on the probability distribution of the productivity of the variable factor. Fitting different distributions to cross-sectional data on U.S. productivity, it is shown that if the elasticity of substitution between human and robotic labor is greater than about 1.9, the burgeoning of AI technologies will cause a decline in aggregate wages, other things equal. For the manufacturing sector, an even smaller human-robot elasticity of substitution is likely to result in declining wages of industrial workers as robots proliferate.     

Bundled discounts: Strategic substitutes or complements?

Bundled discounts by pairs of otherwise independent firms play an increasingly important role as a strategic tool in several industries. Given that prices of firms competing for the same consumers are strategic complements, one would expect their discounts levels also to be strategic complements. However, in this paper we show that under some circumstances bundled discounts may be strategic substitutes. This occurs under vertically differentiated products where a low quality pair of producers may indeed prefer to lower its discount after an increase in the discount offered by a high quality pair of producers.     

Are contributions of time and money substitutes or complements?

This article empirically investigates the relationship between donations of time and money using Canadian tax policy reforms that changed the tax price of charitable donations. The 1988 reform where a charitable tax deduction was converted to a credit and the 2000 reform in provincial income taxes provide tax price variations plausibly exogenous to individuals’ unobserved heterogeneity. Our estimates on cross-price effects imply that individuals make more time donations as the tax price of charitable donations increases and hence money and time donations are substitutes, as some theories would imply. This contrasts with earlier findings using cross-sectional data.     

Energy and capital: substitutes or complements? Some results for the UK industrial sector

This paper investigates the substitutability or complementarity possibilities between capital, labour and energy in the UK industrial sector, with particular attention to the captial-energy relationship. It is found, using the translog-cost-function approach, that capital and labour as well as energy and labour are substitutes. However, capital and energy are found to be complements.     

Capacity utilization rates and unemployment rates: are they complements or substitutes in warning about future inflation?

This research examines capacity utilization as a measure of economic slack in the US economy. Many macroeconomists have questioned the use of capacity utilization as a measure of economics slack on several fronts. The first issue revolves around the definition and accuracy of measurement of the capacity utilization rate in the US economy. Since this research use existing Federal Reserve measures of capacity utilization no insights into the definition and measurement issues are offered other than the fact that a consistent role is found for two different Fed measures of capacity utilization in explaining inflation. The second issue effectively involves the concern as to robustness of the link between the capacity utilization rate and inflation. It was found that there is indeed reason for the Federal Reserve to take note of changes in capacity utilization when trying to determine its policy position with regard to inflation. Clearly, the high capacity measure developed in this research offers distinct information about the inflation process. The third issue raises the question as to whether the capacity utilization and unemployment rates are complements or substitutes in the inflation equation. Both rates tend to provide similar information regarding price changes at low levels of aggregate resource usage. However, as resource usage in the economy becomes increasingly close to its maximum potential, the labour market impact on inflation, as capture by unemployment rate measures, is distinctly different from that of capacity constraints. Finally, if the capacity utilization rate is indeed a useful measure of inflationary pressure, is there a threshold level of the capacity utilization rate above which policymakers should become particularly concerned about the potential of accelerating inflation? It was found that across two measures of inflation, the widely discussed capacity threshold level is in the 84-85% range.     

International reserves and swap lines: Substitutes or complements?

Developing Asia experienced a sharp surge in foreign currency reserves prior to the 2008–9 crisis. The global crisis has been associated with an unprecedented rise of swap agreements between central banks of larger economies and their counterparts in smaller economies. We explore whether such swap lines can reduce the need for reserve accumulation. The evidence suggests that there is only a limited scope for swaps to substitute for reserves. The selectivity of the swap lines indicates that only countries with significant trade and financial linkages can expect access to such ad hoc arrangements, on a case by case basis. Moral hazard concerns suggest that the applicability of these arrangements will remain limited. However, deepening swap agreements and regional reserve pooling arrangements may weaken the precautionary motive for reserve accumulation.     

Shadows of the past: path dependence of TV on its sub-systems,complements and substitutes

In this study, two levels of path dependence in the television technological system are examined: (1) How does the development of television (TV) core components affect the development of peripheral components? and (2) How does the development of complementary and substitute technologies affect the development of television technology? Results from the empirical analysis using patents from 1975 to 2004 indicate that: (a) the development of TV periphery technologies is path-dependent on the development of TV core technologies and (b) even after controlling for its own prior history, the development of the TV system is path-dependent on the development of its complementary technologies. However, there is weak evidence of the path dependence of the TV system on the development of its substitute technologies.     

Why are governmental R&D and private R&D complements?

It is well known that government R&D and private R&D have a complementary relationship. However, no previous study has provided an explanation for why that complementary relationship exists. This paper argues that infratechnology is the critical link between governmental and private R&D and that the observed complementarity is the result of technical complementarity at the production level between funding, infratechnology, and knowledge sharing. A theoritical framework based on this argument is developed and examined empirically for supporting evidence. Evidence of technical complementary is found as well as evidence that governmental R&D stimulates the sharing of knowledge.     

Comparing alleged incommensurables: Institutional and Austrian economics as rivals and possible complements? ∗

The purpose of this article is to explore the changing relationship between Austrian and Institutional economics and the common ground that they appear increasingly to share. It is maintained that both parties have something to learn from each other - there are gains to be made from intellectual trade and inter-research tradition discourse. Neither Austrian economics nor institutional economics presently provides a sufficiently robust or sophisticated approach to individual and group problem-solving activity within institutional-knowledge constraints and historical time dynamics, yet they are both beginning to seriously grapple with such issues. The gulf between the Austrian and Institutional research traditions is narrowing given that there is some convergence toward a middle ground where it is recognized that individuals do not exist in a vacuum and that institutions both constrain and enable purposeful behaviour. Through increased interaction Austrians may learn to take ‘institutional’ frameworks even more seriously whilst Institutionalists may learn to be even more earnest in their treatment of ‘individual’ action within a historical time continuum.     

Public and private measures of consumer confidence in Turkey： Substitutes or complements

Consumer confidence indices are among the major economic variables as private consumption stands as the major component of aggregate demand in many economies. This is also relevant for an emerging economy like Turkey. ＂What determines consumer confidence？＂ is one of the most popular questions in the literature of consumer surveys. There are two consumer confidence indices regularly released in Turkey. One is released by a private corporation, CNBC-e, in the first day of every month since January 2002. The other one is released by two public institutions, Central Bank of the Republic of Turkey （CBRT） and Turkish Statistical Institute （TURKSTAT）, jointly since 2004. Although the goal is the same for both indices, there are differences between them in terms of the methodology and sampling size. This study has two aims： One is to detect the degree of correlation between these indices which will allow for commenting on the reliability of the indices; The other one is to test the relation between Gross Domestic Product （GDP）, unemployment rate variables and the consumer confidence in Turkey by using both indices.     

Complements or substitutes? New theoretical considerations and empirical evidence on the imports and FDI relationship in Central and Eastern European Countries

This paper addresses the imperative need to understand the relationship between inward FDI and trade by developing a new conceptual approach and providing empirical evidence. We use an expanded time dataset, from 1992 to 2008 and an enriched dataset of countries, sectors and location factors. In regards to the inward FDI versus imports relationship, results comply with our theoretical formulation and strongly indicate an overall complementarity with each other. In the case of FDI we find strong locational characteristics such as the large market size, the gradual improvement of the macro-environment and finally the quality of labour force to play a positive role.     

Brunner and Leijonhufvud: friends or foes?

Karl Brunner and Axel Leijonhufvud constantly pointed out the prominence of imperfect information in macroeconomic analysis. This paper argues that, despite strong oppositions related to their rival schools of thought, this emphasis on informational problems led them to adopt similar views on many theoretical and methodological issues. These issues encompass the perception of the economic agent in society, the theory of price inflexibility and unemployment, the role of relative prices, the importance of signal-extraction problems and the position within the Marshall-Walras divide.     

Are nontariff measures and tariffs substitutes? Some panel data evidence

Using new estimates of ad valorem equivalent of nontariff measures (NTMs) over time, this paper examines NTMs and tariffs’ relationship for a sample of 70 economies for 4,949 products at the 6‐digit harmonized system level over the period 2003–2015. A panel data methodology models the lagged adjustment of NTMs to tariffs, consistent with a causal relationship. Trade policy substitution is found when the models are estimated in both levels and changes; with this holding for both OECD and non‐OECD countries, but not for the agriculture sector in OECD countries. Overall, there is a fairly complete substitution between policy instruments in absolute terms.     

Are financial development and corruption control substitutes in promoting growth?

While financial development and corruption control have been studied extensively, their interaction has not. We develop a simple model in which low corruption and financial development both facilitate the undertaking of productive projects, but act as substitutes in doing so. The substitutability arises because corruption raises the need for liquidity and thus makes financial improvements more potent; conversely, financial underdevelopment makes corruption more onerous and thus raises the gains from reducing it. We test this substitutability by predicting growth, of countries and industries, using measures of financial development, lack of corruption, and a key interaction term. Both approaches point to positive effects from improving either factor, as well as to a substitutability between them. The growth gain associated with moving from the 25th to the 75th percentile in one factor is 0.63–1.68 percentage points higher if the second factor is at the 25th percentile rather than the 75th. The results show robustness to different measures of corruption and financial development and do not appear to be driven by outliers, omitted variables, or other theories of growth and convergence.     

Vertical differentiation and collusion: Pruning or proliferation?

In this paper, we tackle the dilemma of pruning versus proliferation in a vertically differentiated oligopoly under the assumption that some firms collude and control both the range of variants for sale and their corresponding prices, likewise a multiproduct firm. We analyse whether pruning emerges and, if so, a fighting brand is marketed. We find that it is always more profitable for colluding firms to adopt a pricing strategy such that some variants are withdrawn from the market. Under pruning, these firms commercialize a fighting brand only when facing competitors in a low-end market.     

A case for complements? Location and attendance in Major League Soccer

As Major League Soccer (MLS) continues to award expansion franchises throughout North America, the league must be considerate of how new clubs may impact attendance levels at nearby clubs. Regardless of whether new MLS clubs are awarded to cities with strong North American Soccer League histories, league officials must be mindful of the effect that geographically close competitors can have on attendance. Perhaps stemming from the limited number of clubs in competition, MLS teams currently appear to operate as strategic complements to one another, increasing season-long attendance as teams locate closer to one another.     

Complementing Cournot’s analysis of complements: unidirectional complementarity and mergers

We study the price and welfare effects of a merger of firms producing unidirectional complements: a firm is producing a product (called an optional good) that is valuable only if it is consumed with the other product (called a base good) produced by another firm. Under the assumption that there are two types of consumers: (i) those who consume one unit of the base good only or nothing (having zero valuation of the optional good), and (ii) those who consume one unit of the composite good or nothing, we show that a merger of the two firms raises the price of the base good, resulting in lower consumer surplus for the former consumer group, if and only if the average willingness to pay in the latter consumer group is sufficiently low. This result is in sharp contrast to Cournot’s (Researches into the mathematical principles of the theory of wealth, 1838) classical implication that a merger of firms producing strict complements makes all consumers strictly better off.     

The new millennium and leadership: evolution or entropy?

Health care in the new millennium will be different. We have a wonderful opportunity to live in a new paradigm of leadership and management that opens up myriad possibilities for innovations in health care and leadership. If leaders stand still and don't quickly adapt to the new demands, they will be killed as leaders in this new millennium. The next 20 years are only for those who can act and adapt quickly.
