Biological well-being in late nineteenth-century PhilippinesJournal articleJean-Pascal Bassino, Marion Dovis and John Komlos, Cliometrica, Volume 12, Issue 1, pp. 33-60, 2018

This paper investigates the biological standard of living in the Philippines toward the end of Spanish rule. We investigate levels, trends, and determinants of physical stature from the birth cohorts of the 1860s to the 1890s using data on 23,000 Filipino soldiers enlisted by the US military between 1901 and 1913. We estimate average heights and use province-level information for investigating the determinants of biological well-being. We find that at 159.3 cm (62.7 inches), the average height of soldiers born in the mid-1870s was very short even for the time. The low biological standard of living observed in late nineteenth-century Philippines was not due to the tropical disease environment alone since greater heights were recorded for the same period in other parts of Asia with a similar climate. The results also indicate a decline of more than 1.5 cm (0.6 inches) in the height of soldiers born between the early 1870s and the late 1880s. This decline occurred at a time when there was an expansion of commercial activity in cash crop production for export. Heights did not regain the level of the 1870s until the late 1930s and early 1940s.

Child Income Appropriations as a Disease-Coping Mechanism: Consequences for the Health-Education RelationshipJournal articleRenaud Bourlès, Bruno Ventelou and Maame Esi Woode, The Journal of Development Studies, Volume 54, Issue 1, pp. 57-71, 2018

This paper analyses the relationships between HIV/AIDS and education taking into account the appropriative nature of child income. Using a theoretical model, we show that considering remittances from one’s child as an insurance asset can reverse the usual negative relationship between disease prevalence and educational investment. This prediction confirms the results of an empirical study conducted on data compiled from the Demographic and Health Survey (DHS) database for 12 sub-Sahara African countries for children aged between 7 and 22-years-old. Using regional HIV prevalence as a measure of health risk, we find that the ‘sign of the slope’ between health risk and the enrolment of children is not constant. Splitting the data based on expected remittance patterns (for example rural versus urban), we obtain that the effect is most likely driven by household characteristics related to child income appropriation.

The impact of setting negative policy rates on banking flows and exchange ratesJournal articleGuillaume A. Khayat, Economic Modelling, Volume 68, pp. 1-10, 2018

In the aftermath of the great contraction of 2008, policymakers were faced with the Zero Lower Bound (ZLB) on nominal interest rates. Central banks implemented several unconventional monetary policies to overcome the ZLB, including setting negative nominal interest rates. This paper explores possible unintended effects of setting negative policy rates. Using Danish data, I assess the impact of paying a negative interest rate on reserves. Results suggest that going into negative territory has a particular impact, distinct from that of simply lowering interest rates: it leads to higher banking outflows and depreciation of the currency. Due to the reluctance of commercial banks to pass on negative rates to their depositors (retail deposits can easily be switched into cash), paying a negative (vs. positive) interest rate on reserves creates a disconnection between the assets and liabilities of commercial banks' balance sheets. Commercial banks can avoid this disconnection by holding external assets or assets in foreign currencies. This incentive to increase banking outflows appears to explain the particular impact of going into negative territory.

A Right to Protection for whistle-blowersBook chapterDaniele Santoro and Kumar Manohar, In: Claiming Citizenship Rights in Europe. Emerging Challenges and Political Agents, D. Archibugi and A. E. Benli (Eds.), 2018, pp. 186-203, Routledge, Taylor and Francis, 2018

In this paper we present a principled view that grounds the need for whistleblowing protection, often missing in the literature. They argue that whistleblowers have a right to protection because of their role in ensuring accountability against wrongdoings that go unnoticed due to unrestrained practices of secrecy. This right derives from the crucial role of whistleblowing in exposing right limitations, in absence of procedures of redress, and information of public interest. Given this role, absence of procedures of protection and fair hearing of disclosure claims puts unfair burdens on whistleblowers so much as to, in some instances, preclude the very possibility of disclosure. In this regard, a cognizance of their role in ensuring protection of rights and structure of accountability demands a system of protection extended to human rights defendants. We argue that the European Union should stand up for the legal protection of whistle-blowers and encourage their contribution towards more transparent institutions and economic transactions.

Dynamic pricing for inventories with reference price effectsJournal articleRégis Chenavaz and Corina Paraschiv, Economics - The Open-Access, Open-Assessment E-Journal, Volume 12, Issue 2018-64, pp. 1-16, 2018

This article presents a dynamic pricing model of a retailer selling an inventory, accounting for consumer behavior. The authors propose an optimal control model, maximizing the intertemporal profit with consumers sensitive to the selling price and to a reference price. The optimal dynamic pricing policy is solved with Pontryagin's maximum principle with a structural (general) demand function. The authors obtain an original pricing rule, which explicitly accounts for the impact of price and inventory on future profits. The dynamics of price do not have to imitate the dynamics of the reference price. Instead, the dynamics of price are tied to opposing effects linked to this reference price. The authors also discuss managerial implications with regards to behavioral pricing policies.

Self-Realization of the Economic AgentBook chapterGilles Campagnolo, In: The Realizations of the Self, Andrea Altobrando, Takuya Niikawa and Richard Stone (Eds.), 2018, pp. 91-109, Springer International Publishing, 2018

Economists ceased at some point to discuss the “self” of the “economic agent.” Moralists criticized them for this. Yet attention had been paid to the “self” from the start of modern economics with Adam Smith “self-love.” Granted, the contemporary mathematized mainstream in economics ignores the “self,” its representations, and its realization through economic life. Economic philosophers, however, bring it to the fore and debate identity issues, the flesh and “reality” of agents beyond an axiomatic skeleton. Inspired by Ancient thought and heterodox individualistic currents (like the Austrian school), the inquiry as to what “self-realization” may, or may not mean in the economists’ realm and in economic life is essential to ethical and methodological issues so as to make sense of how to realize the self from an economic viewpoint (and far from popular folk psychology).

Modelling Foreign Exchange Realized Volatility Using High Frequency Data: Long Memory versus Structural BreaksJournal articleAbderrazak Ben Maatoug, Rim Lamouchi, Russell Davidson and Ibrahim Fatnassi, Central European Journal of Economic Modelling and Econometrics (CEJEME), Volume 10, Issue 1, pp. 1-25, 2018

In this study, we model realized volatility constructed from intra-day highfrequency data. We explore the possibility of confusing long memory and structural breaks in the realized volatility of the following spot exchange rates: EUR/USD, EUR/JPY, EUR/CHF, EUR/GBP, and EUR/AUD. The results show evidence for the presence of long memory in the exchange rates' realized volatility. FromtheBai-Perrontest,wefoundstructuralbreakpointsthatmatch significant events in financial markets. Furthermore, the findings provide strong evidence in favour of the presence of long memory.

De l'utilité de l'impôt pour freiner l'effet de levier du « hors-bilan » des banques / About the Utility of Taxation to Curb the Impact of Leverage Effect of Banks Off-Balance SheetJournal articleJean-Paul Nicolaï and Alain Trannoy, Revue d'économie financière, Volume N° 131, Issue 3, pp. 151-169, 2018

[Fr] Les normes comptables IFRS ont intégré dans le bilan des banques l'essentiel des instruments financiers dérivés que nous considérons ici sous le terme de « hors-bilan », au prix d'une certaine invisibilité de leur « effet de levier ». Nous décrivons l'activité des banques de financement et d'investissement et montrons que ces instruments dérivés correspondent à une fonction d'intermédiation du risque dans l'économie où les banques ne « portent » pas ce risque au bilan, contrairement au métier bancaire traditionnel de « transformation ». Nous décrivons la banque comme une source d'« accroissement des possibles de la taille du marché » que nous définissons au préalable d'une manière générale. Une telle source, comme toute innovation, est synonyme de risque. Le « hors-bilan » bancaire apparaît dans ce cadre comme un effet de levier sans limite naturelle. Nous étudions alors ce que pourraient être des fiscalités adaptées à trois objectifs différents : corriger et capter les rentes, limiter le risque systémique, maîtriser l'« accroissement des possibles ». Une assiette considérant une mesure des engagements en valeur absolue associés aux positions sur les produits dérivés, dans le bilan des banques, paraît pertinente pour limiter l'accroissement des possibles et, partant de là, le risque.
[Eng] The accounting standard IRFS have integrated the bulk of derivatives (the off-balance sheet in this paper) in the balance sheet of the banks at the cost of masking their leverage effect. We describe the bank activity and we show that these derivatives correspond to a financial intermediation function of the banking system, which supplements the standard lending role of banks. We show that the banking activity naturally increases the possibility set of the capital market that we define in general terms. As all innovations, this increase bears additional risk. The off-balance sheet appears in this framework as bringing a leverage effect without natural limit. We study what could be the role of different types of taxes: first, correcting and capturing the rents, second, limiting the systemic risk, third, mastering the “growth of the feasible set”. A tax base consisting in financial liabilities (in absolute value) associated to positions on financial derivatives may be viewed as well-focused to limit the growth of the possibility set and therefore of the risk.

Solidarité sociale et proximités : de l’État providence aux communs sociauxJournal articleJacques Garnier and Jean-Benoît Zimmermann, Espaces et societes, Volume n° 175, Issue 4, pp. 19-33, 2018

Cet article traite des formes de solidarité sociale nouvelles qui émergent aujourd’hui dans le double contexte d’accentuation des inégalités socio-spatiales et d’altération du système français de solidarité nationale. Nous analysons les conditions qui font que ce système devient de plus en plus inopérant face à des situations d’inégalité d’une diversité croissante, à la fois multiscalaires, multifactorielles et cumulatives. En nous appuyant sur une approche théorique en termes de proximité, et en nous référant aux situations largement évoquées aujourd’hui dans la littérature, nous mettons en évidence les conditions qui favorisent désormais l’apparition de « communs sociaux ». Nous montrons en quoi ces communs se distinguent des modalités anciennes de solidarité communautaire. Nous soulignons enfin à quelles conditions ces communs sont susceptibles de constituer des réponses justes et durables à l’accentuation actuelle des inégalités sociales.
