Investigating the determinants of patent acquisition in biotechnology: an empirical analysis

Acquiring patents is an increasingly relevant opportunity for innovating companies, especially after the rise and development of the so-called markets for technologies (MFTs). However, only scant attention has been devoted to investigate patents' characteristics influencing their acquisition by organisations. Accordingly, this paper aims at filling this gap by analysing how four main characteristics – as patent scope, scientific knowledge cited by the patent, forward patent citations, and number of patent claims – impact the likelihood of patent acquisition. We based our statistical analysis on a sample of 9716 US Patent and Trademark Office patents assigned to 165 biotechnological firms. Results support our conjectures and offer interesting managerial implications for organisations operating within MFTs indicating which characteristics make patented technological solutions more likely to be acquired by other firms, as a narrow scope, inclusion of scientific knowledge, and a number of forward citations able to increase patent's impact and exclusion rights.     

An empirical analysis on the determinants of overweight and obesity in China

Overweight and obesity in adult populations is considered to be a growing epidemic worldwide, and appears to be rapidly increasing in China. From 1992 to 2002, the incidence of overweight in adults increased by 39.0%, while that of obesity doubled. To identify the determinants of adult overweight and obesity in China, micro-level data from a questionnaire survey entitled the ‘Preference Parameters Study,’ which was conducted by the Global Centers of Excellence programme at Osaka University, were analysed. In addition to the entire sample, data from urban and rural subsamples were also analysed in order to investigate whether the determinants of overweight and obesity differed. The results suggested that body mass index (BMI) is correlated with subjective well-being, gender, age, labour intensity and drinking and eating habits among urban respondents, and with age, monthly income, number of siblings and eating habits among rural respondents.     

The empirical analysis of the determinants for environmental technological change: A research agenda

Technological change is usually considered a necessary albeit not sufficient condition for a transition to sustainability. However, the empirical analysis of the determinants to environmental technological change has not received too much attention in the environmental/ecological economics literature and many open questions remain in this context. Based on a careful review of the literature, this paper argues that further analysis should address several issues at different levels: i.e., regarding the conceptual framework, the thematic scope of the studies, some methodological issues and other aspects related to the environmental policy variable. First, an integrated conceptual framework which takes into account the interplay between relevant variables influencing environmental technological change (i.e., factors internal and external to the firm and characteristics of the environmental technologies) and all the stages of this process, with a greater emphasis on the invention stage, should be developed. Other aspects should then be tackled, including a focus on several themes (i.e., a greater attention to cross-sectoral technologies, the barriers to different types of environmental technologies, the international dimension of environmental technological change and environmental technological change in small and medium size enterprises), methodological issues (combination of case studies and econometric modelling) and several issues related to the environmental policy variable.     

Human appropriation of net primary production in the United Kingdom, 1800-2000 : Changes in society's impact on ecological energy flows during the agrarian-industrial transition

This paper presents an empirical analysis of the United Kingdom's society's long-term intervention into the energy flows of domestic terrestrial ecosystems through the human appropriation of aboveground net primary production (aHANPP) covering the period 1800-2000. The depicted aHANPP trajectory and the historical development of its components are discussed in view of a continuously increasing population and the transition process from an agrarian to an industrial socioecological regime. During the 19th century, aHANPP shows a steady decline from its level of 71% in 1800. While even higher levels were reached during the mid 20th century, the trend during the last forty years of the period under investigation again shows a reduction of aHANPP, which lies at 68% in the year 2000. The high values of aHANPP in the United Kingdom are primarily attributable to the limited amount of forest in comparison to large agricultural areas. At the beginning of the studied period, the relative stabilisation or even decrease in aHANPP in comparison to population development was made possible through the area expansion of and productivity increases on cropland and permanent pastures. Later this was made possible through the outsourcing of biomass harvest, by satisfying local nutritional demands by means of overseas imports, and as from the mid 20th century through huge amounts of fossil fuel based inputs into agriculture (e.g. increased amounts of fertilizers and motorized traction) which allowed increases in biomass harvest to be decoupled from HANPP.     

The determinants of the vote for Trump: an analysis of Texas 2016 primary results

This article analyses the 2016 primary vote for Donald Trump in Texas. Much of Trump’s campaign rhetoric has been anti-immigrant. A major Trump campaign theme was his proposal to build a wall along the Mexico-U.S. border and make Mexico pay for it (Trump 2016). The econometric model estimated below uses county-level data for Texas. The dependent variable is the percent of the 2016 republican primary vote for Mr Trump. The model examines the electoral effects of Trump’s anti-immigrant rhetoric in a heavily Hispanic border state.     

The participation decision versus the level of participation in an environmental treaty: a spatial probit analysis

This paper represents treaty participation as a two-stage game, for which nations first decide whether or not to participate and then they choose their level of participation. The resulting subgame perfect equilibrium is used to derive a reduced-form equation for estimating and separating the influences of the variables at the two decision stages. This spatial probit equation forms the basis for a full-information maximum likelihood estimator that accounts for the simultaneity bias associated with public good spillins at both stages. When the procedure is applied to the Helsinki Protocol, we find that the strategic influence of a variable may drastically differ depending upon which stage is scrutinized.     

Technology acquisition models for fast followers in high-technological markets: an empirical analysis of the LED industry

The rapid rate of technology obsolescence in many high-technology markets makes it imperative for firms to renew their technological bases constantly. Given its critical importance, the technology acquisition from the fast followers’ perspective needs to be the subject of careful analysis. This paper aims to identify the factors influencing fast-follower firms’ choice of technology acquisition model, using a multi-factorial analysis and taking into account their technological capabilities, marketing capabilities, and environmental risk tradeoffs. This study sourced data from the Securities Data Company (SDC) Platinum Database for a total of 205 instances of technological cooperation between technology holders and fast followers in the LED industry. Based on the empirical results, some significant findings were found. First, regarding technological capabilities, when fast-follower firms had greater R&D, complementary manufacturing capabilities, and technological similarities with the partners, they preferred the acquisition model that required higher resource commitments. Secondly, when fast followers had marketing channel advantages, they were more likely to choose a high resource-commitment acquisition model to obtain time-to-market benefits.     

The contest for mineral wealth: an economic analysis of conflicts in Ghanaian mining communities

The paper uses survey data from 1458 households in 60 communities from 24 districts in 5 regions of Ghana and logistic regression to examine conflicts as a contest for mineral wealth in mining communities, estimates the determinants of conflicts in these mining communities and examines how these contests could erode and/or enhance Ghana’s gains from mining. The paper finds that the likelihood of a conflict occurring in a mining area is about 56.7%. Village effect was found to be a significant positive predictor of mining conflict. Also, improvement in primary education, employment opportunities to community members of ages 25–50, the strength of institutions and the absence of small-scale miners in a mining community reduces the probability of conflicts occurring by 12.8, 35.8, 6.57 and 17.7%, respectively. While an increase in pollution levels increases the likelihood of conflicts occurring by 7.1%, primary occupation in manufacturing and services, and increase in household monthly expenditure significantly increases the likelihood of conflicts within the mining communities as the cost of living increases.     

Human appropriation of aboveground net primary production in Spain, 1955-2003: An empirical analysis of the industrialization of land use

The human appropriation of net primary production (HANPP) is an indicator of the human domination of ecosystems that measures to which extent human activities alter the amount of biomass available each year in ecosystems. This paper analyses the development of aboveground HANPP (aHANPP) in Spain for the period from 1955 to 2003. During this period, Spain's agriculture underwent a transition from a largely pre-industrial to a highly intensified production system. Changes in land use patterns include a reduction of cropland area and an expansion of forest area. Results show that aHANPP declined from 67% of potential aNPP in 1955 to 61% in 2003. Biomass harvest strongly increased from 68 million tons dry matter biomass per year (Mt/yr) to 106 Mt/yr, with nearly all of this increase occurring on cropland. Productivity losses due to human-induced land conversions dropped significantly from 112 Mt/yr to 63 Mt/yr, mainly as a result of the surge in cropland productivity and the increase in forest area. Despite its decrease during the last decades, aHANPP in Spain is still at a remarkably high level in comparison with the global average or other industrialized countries.     

Structural change in Finnish manufacturing: The theory of the aggregation of production functions and an empirical analysis with a plant-level panel

In this paper, structural change in the Finnish manufacturing industries is studied using the theory of the aggregation of production functions and longitudinal plant-level data for the period from 1980 to 2005. To characterise the nature of structural change in 12 industries, we examine the invariance of aggregate production functions over time. Aggregate production functions need not be estimated because, according to the theory of the aggregation of production functions, the invariance can be analysed by investigating the stability of capacity density functions, which describe the distribution of value added in these industries. Even though the shapes of aggregate production functions alter over time in most industries, there are differences in timing and in the degree of turbulence across industries. The analysis confirms that in some industries (e.g., the paper industry) the late 1980s marked the beginning of a period of relatively strong structural change. The food and communications equipment manufacturing industries are examples of industries for which the 1990s was a period of turbulence.     

EDGAR on the internet: The welfare effects of wider information distribution in an experimental market for risky assets

Policies such as the SEC’s Fair Disclosure Rule, and technologies such as SEC EDGAR, aim to disseminate corporate disclosures to a wider audience of investors in risky assets. In this study, we adopt an experimental approach to measure whether this wider disclosure is beneficial to these investors. Price-clearing equilibrium models based on utility maximization and non-revealing and fully-revealing prices predict that in a pure exchange economy, an arbitrary trader would prefer that no investors are informed rather than all are informed; non-revealing theory further predicts that an arbitrary trader would prefer a situation in which all traders are informed rather than half the traders are informed. These predictions can be summarized as “None > All > Half”. A laboratory study was conducted to test these predictions. Where previous studies have largely focused on information dissemination and its effects on equilibrium price and insider profits, we focus instead on traders’ expected utility, as measured by their preferences for markets in which none, half, or all traders are informed. Our experimental result contradicts the prediction and indicates “Half > None > All”, i.e. subjects favor a situation where a random half is informed. The implication is that in addition to testing predictions of price equilibrium, experiments should also be used to verify analytical welfare predictions of expected utility under different policy choices.
