Euro Effect on Trade in Final, Intermediate and Capital Goods
The aim of this paper is to provide fresh evidence on the effect of the adoption of the euro on exports of different types of goods. The novelty with respect to previous research is threefold. First, disaggregated trade data are used to allow for heterogeneous effects for final intermediate and capital goods. Second, we distinguish between the euro effect on the extensive and the intensive margins of trade. Finally, we estimate the impact of the Euro adoption controlling for exchange rate volatility, exchange rate movements and EU membership. This allows us to disentangle the effect of a common currency beyond the elimination of trade barriers and of any variation in the exchange rate. The main results indicate that the impact of the Euro on trade values (intensive margin) is around 9% for intermediates, 7% for final goods and it is negative for capital goods. Interestingly, the Euro effects on the extensive margin of trade are found to be negative and significant for the three types of goods, pointing to increasing specialization.Financial support from the Spanish Ministry of Economy and Competitiveness is grateful acknowledged (ECO2014-58991-C3-2-R)
What Explains Indirect Exports of Goods and Services in Eastern Europe and Central Asia?
This paper investigates the determinants of indirect exporting, using firm-
level data for 27 countries in Eastern Europe and Central Asia. Indirect exporting
depends on a combination of fixed and variable trade cost factors. We first
hypothesize that firms that perceive customs, transportation, crime and legal sys-
tems as severe obstacles anticipate higher fixed costs and are more likely to export
indirectly. The second hypothesis is that indirect exporting tends to be a temporary
strategy. Econometric models are used to test the first hypothesis and transition
matrices to test the second. In particular, probit, Heckman-probit and fractional
response models are estimated to analyse the determinants of the export mode and
the share of indirect exports. The results indicate that the factors that account for the
fixed cost of exporting, mainly affect the decision to export indirectly (extensive
margin), but some of them also affect, to a lesser extent, the amount exported
indirectly (intensive margin). More specifically, factors such as customs and trade
restrictions and transportation obstacles affect the extensive margin only, whereas
crime affects both margins. Secondly, trade agreement membership mainly affects
trade in manufactured goods, while exchange rate volatility affects positively the
extensive and intensive margin of indirect exports of services. The results also
indicate that firms are more likely to change their status as an indirect exporter than
they are to change their status as a direct exporter or a non-exporter, which provides
support to the second hypothesis

The
Gravity of Arms
Abstract
The aim of this paper is to investigate the determinants of international arms transfers
in a gravity
model framework
.
By distinguishing between the decision to export arms (extensive margin) and
the value of the arms exported (intensive margin), while also considering its interdependence, is
what differentiates this paper from
previous research
.
A

gravity model of
trade augmented with political
and security motives
is estimated using a two

stage panel data
approach for 104 exporting countries over the period from 1950 to 2007.
In addition to the usual
gravity variables related to the economic mass
of the trading countries and the trade cost factors, the
model is extended with political and security factors.
T
he level of democracy in both trading
partners
,
political differences between trading partners and
voting similarity with the

General Assembly
of the countries engaged in trade
are the main political factors
,
whereas the existence of
conflicts,
military
pacts and embargoes are taken as security motives
. The
key
result indicates that
both
political
and security motives
are an
important determinant of
an
arms
trade
, but
their effects on the extensive margin of exports (the decision to order a transfer) differs
from their effect on the intensive margin (average value of exports)
. Moreover

Contact cleaning of polymer film solar reflectors
This paper describes the accelerated ageing of polymer film reflecting surfaces under the conditions to be found during contact cleaning of Concentrating Solar Power (CSP) collectors in the presence of dust and sand particles. In these situations, contact cleaning using brushes and water is required to clean the reflecting surfaces. Whilst suitable for glass reflectors, this paper discusses the effects of existing cleaning processes on the optical and visual properties of polymer film surfaces, and then describes the development of a more benign but effective contact cleaning process for cleaning polymer reflectors. The effects of a range of cleaning brushes are discussed, with and without the presence of water, in the presence of sand and dust particles from selected representative locations. Reflectance measurements and visual inspection shows that a soft cleaning brush with a small amount of water can clean polymer film reflecting surfaces without inflicting surface damage or reducing specular reflectance

LINKING FIRMS IN VALUE BUSINESS ECOSYSTEMS: TOWARDS A CLASSIFICATION MODEL
This paper contributes to the business ecosystem literature by offering a classification model that allows for the differentiation of intercompany connections. The researchers found that the definition of a business ecosystem lacks separation in the types of connection between companies. Business ecosystems were found to differentiate significantly, from loosely coupled to highly regulated and organised company relationships. Work with practitioners has shown that some may even result in newly founded business ventures. The authors are therefore proposing a classification model for business ecosystems that allows further classifications in studies. The outcome of this study has helped practitioners to operationalise product service and service business ecosystems
An exploratory social network analysis of academic research networks
For several decades, academics around the world have been collaborating with the view to support the development of their research domain. Having said that, the majority of scientific and technological policies try to encourage the creation of strong inter-related research groups in order to improve the efficiency of research outcomes and subsequently research funding allocation. In this paper, we attempt to highlight and thus, to demonstrate how these collaborative networks are developing in practice. To achieve this, we have developed an automated tool for extracting data about joint article publications and analyzing them from the perspective of social network analysis. In this case study, we have limited data from works published in 2010 by England academic and research institutions. The outcomes of this work can help policy makers in realising the current status of research collaborative networks in England
Attentional filtering of visual information by neuronal ensembles in the primate lateral prefrontal cortex.
The activity of neurons in the primate lateral prefrontal cortex (LPFC) is strongly modulated by visual attention. Such a modulation has mostly been documented by averaging the activity of independently recorded neurons over repeated experimental trials. However, in realistic settings, ensembles of simultaneously active LPFC neurons must generate attentional signals on a single-trial basis, despite the individual and correlated variability of neuronal responses. Whether, under these circumstances, the LPFC can reliably generate attentional signals is unclear. Here, we show that the simultaneous activity of neuronal ensembles in the primate LPFC can be reliably decoded to predict the allocation of attention on a single-trial basis. Decoding was sensitive to the noise correlation structure of the ensembles. Additionally, it was resilient to distractors, predictive of behavior, and stable over weeks. Thus, LPFC neuronal ensemble activity can reliably encode attention within behavioral time frames, despite the noisy and correlated nature of neuronal activity
Museum of Latino History Feasibility Study
The State of California, in considering the feasibility of a proposal for a State Museum of Latino History retained the consulting team of Economics Research Consultants, Florian Martinez Associates, and J. Wetzel Associates to conduct a study. The museum’s purpose would be to provide a venue for displaying artifacts, exhibits, and cultural programs which educate the public as to the historical development and contributions of Latinos to California specifically and America generally. The resulting report has the following sections: introduction, summary and conclusions, concept statement, attendance analysis, space requirements, museum location and site analysis, financial analysis, and organization and implementation recommendations
Recognizing Unit Multiple Intervals Is Hard
Multiple interval graphs are a well-known generalization of interval graphs introduced in the 1970s to deal with situations arising naturally in scheduling and allocation. A d-interval is the union of d intervals on the real line, and a graph is a d-interval graph if it is the intersection graph of d-intervals. In particular, it is a unit d-interval graph if it admits a d-interval representation where every interval has unit length. Whereas it has been known for a long time that recognizing 2-interval graphs and other related classes such as 2-track interval graphs is NP-complete, the complexity of recognizing unit 2-interval graphs remains open. Here, we settle this question by proving that the recognition of unit 2-interval graphs is also NP-complete. Our proof technique uses a completely different approach from the other hardness results of recognizing related classes. Furthermore, we extend the result for unit d-interval graphs for any d ⩾ 2, which does not follow directly in graph recognition problems -as an example, it took almost 20 years to close the gap between d = 2 and d > 2 for the recognition of d-track interval graphs. Our result has several implications, including that recognizing (x, …, x) d-interval graphs and depth r unit 2-interval graphs is NP-complete for every x ⩾ 11 and every r ⩾ 4
Does German Development Aid boost German Exports and German Employment? A Sectoral Level Analysis
This paper uses an augmented gravity model of trade to investigate the
link between German development aid and sectoral exports from Germany to aid
recipient countries with data from 1978–2011. The findings indicate that in the
long run each dollar of German aid is associated with an average increase of
US$ 0.83 US of German goods exports. The sectors that benefit the most in terms
of exports and employment are machinery, electrical equipment and transport
equipment. According to our estimates using input-output analysis and a partial
equilibrium framework, the aid-induced gains in sectoral exports are associated
with the gross employment of approximately 216,000 people.We would like to thank the German Ministry for Economic Cooperation and Development (BMZ) for financing the study. We are extremely grateful to Bart Los (University of Groningen Europe’s leading institution in inputoutput-analysis) for his assistance in computing the employment effects. The comments of the three anonymous referees clearly helped to improve the paper
and so did the suggestions that we received at workshops and conferences
