Assessing the Impact of Real Shocks on Small Dollarized Economies

This paper compares the impact of real shocks on small open economies operating under two opposite corner solutions: flexible exchange rates and official dollarization. Using an asymmetric two-country model of policy coordination, we show that although a pegged regime like dollarization is an effective device to achieve price stability, small open economies might be better off under a flexible exchange rate regime than under dollarization following any symmetric or asymmetric real shock. We also consider the claim that many small economies have only a limited ability to use their own monetary policy effectively and contrast the dollarization regime with one in which a small open economy follows "fear of floating" practices. In this case, we observe that unless its size is trivial, maintaining monetary policy sovereignty--even if it is not fully exploited--allows the domestic economy to experience lower losses from stabilization in the face of symmetric shocks. Only when an economy is negligibly small, are the costs of stabilization following "fear of floating" practices the same as those under dollarization.Credibility problems; dollarization; fear of floating; real shocks

Monetary and Fiscal Policy Coordination

Motivated by the accession of new member states into the European Union, this paper examines the appeal of taking part in a large monetary union from the perspective of small open economies. Consistent with existing findings in the literature, we show that in the absence of fiscal policy considerations, taking part in a large monetary union is counterproductive for a small economy. Nevertheless, once the role of fiscal policy is properly incorporated, taking part in the monetary union becomes desirable from a social perspective. Following these results, we explore the prospects of engaging both economies in fiscal coordination and on how different schemes of policy synchronization can provide the grounds to make cooperation beneficial for the members of a monetary union. We find that when monetary and fiscal authorities cooperate and attempt to exploit externalities for their own benefit, a Pareto efficient outcome can be achieved if fiscal policy in the monetary union is coordinated by a central authority and such authority acts as a Stackelberg leader vis-à-vis the central bank. Our analysis suggests that this regime result superior to (i) a monetary union in which fiscal authorities conduct their policy in an independent or (ii) coordinated fashion, (iii) to a regime where both authorities internalize the effects of their own externalities by allowing the central bank to act as Stackelberg leader and (iv) event to a regime in which the small open economy decides to stay out of the monetary union.Common central bank; policy co-ordination; monetary union; monetary leadership; fiscal leadership

Political pressure and procyclical expenditure: An analysis of the expenditures of state governments in Mexico

© 2014 Elsevier B.V. Government expenditures are procyclical if they increase in periods of economic growth and decrease in periods of economic downturn. This paper tests the proposition that (within federations) political pressures for public expenditure increase the likelihood that expenditures and intergovernmental transfers will be procyclical. An analysis of political pressures in Mexico suggests that political pressures will produce a distinct pattern of procyclical expenditures across fiscal tiers and across government budgets. This prediction is tested with reference to the expenditures of 31 states in Mexico between 2005 and 2010

Labor productivity and remuneration across Mexico's manufacturing industry: A spatial approach

This document investigates the relationship between wages and labor productivity in Mexico, considering the territorial dimension and, within it, the impact that the productivity of neighboring entities has on local wages, given the geographical proximity. Results show that an increase in labor productivity impacts remuneration. Moreover, an increase in productivity in a particular state positively impacts the remunerations of neighboring states. The results allow us to understand that territorial productivity has a spillover effect on the remunerations of neighboring territories

Relación entre productividad laboral y remuneraciones: un análisis de proximidad espacial a nivel estatal en la industria manufacturera en México, 2004, 2009, 2014 y 2019

En este documento se analiza la relación entre las remuneraciones y la productividad laboral en México, a nivel estatal, considerando el impacto que la productividad de las entidades vecinas tiene en las remuneraciones locales. La omisión de la estructura espacial en las estimaciones puede conducir a un sesgo en el cálculo del parámetro de productividad. En algunas teorías económicas se considera que los incrementos de la productividad laboral deberían traducirse en aumentos de las remuneraciones. A su vez, dadas las relaciones económicas y productivas entre los territorios, es posible que la productividad de las entidades vecinas tenga un impacto positivo en las remuneraciones locales. En este estudio también se incluyen variables de control. La hipótesis central de la investigación es que existe una relación lineal entre las remuneraciones y la productividad cuando se incorpora en el análisis la estructura espacial.Resumen .-- Introducción .-- I.

Antimicrobial potential of AH Plus supplemented with bismuth lipophilic nanoparticles on E. faecalis isolated from clinical isolates

The objective of this study was to determine the antimicrobial potential of AH plus supplemented with bismuth lipophilic nanoparticles (BisBAL NPs) on the growth of Enterococcus faecalis isolated from patients with endodontic infections. BisBAL NPs, synthesized with the colloidal method, were characterized, in its pure form or AH Plus-absorbed, by energy-dispersive X-ray spectroscopy and scanning electron microscopy (EDS-SEM). Antimicrobial activity was evaluated with disc diffusion assays, and antibiofilm activity with fluorescence microscopy. BisBAL NP-supplemented AH Plus had a 4.9 times higher antimicrobial activity than AH Plus alone ( p = 0.0001). In contrast to AH Plus alone, AH Plus supplemented with BisBAL NP inhibited E. faecalis biofilm formation. The sealing properties of AH plus were not modified by the incorporation of BisBAL NPs, which was demonstrated by a 12-day split-chamber leakage assay with daily inoculation, which was used to evaluate the possible filtration of E. faecalis . Finally, BisBAL NP-supplemented AH plus-BisBAL NPs was not cytotoxic for cultured human gingival fibroblasts. Their viability was 83.7% to 89.9% after a 24-h exposure to AH Plus containing 50 and 10 µM BisBAL NP, respectively. In conclusion, BisBAL NP-supplemented AH Plus constitutes an innovative nanomaterial to prevent re-infection in endodontic patients without cytotoxic effects

Cumulative antitumor effect of bismuth lipophilic nanoparticles and cetylpyridinium chloride in inhibiting the growth of lung cancer

Objective: To determine the combined antitumor effect of bismuth lipophilic nanoparticles (BisBAL NP) and cetylpyridinium chloride (CPC) on human lung tumor cells. Material and methods: The human lung tumor cells A549 were exposed to 1–100 µM BisBAL NP or CPC, either separately or in a 1:1 combination. Cell viability was measured with the PrestoBlue assay, the LIVE/DEAD assay, and fluorescence microscopy. The integrity and morphology of cellular microtubules were analyzed by immunofluorescence. Results: A 24-h exposure to 1 µM solutions reduced A549 growth with 21.5% for BisBAL NP, 70.5% for CPC, and 92.4% for the combination ( p < 0.0001), while a 50 µM BisBAL NP/CPC mixture inhibited cell growth with 99% ( p < 0.0001). BisBAL NP-curcumin conjugates were internalized within 30 min of exposure and could be traced within the nucleus of tumor cells within 2 h. BisBAL NP, but not CPC, interfered with microtubule organization, thus interrupting cell replication, similar to the action mechanism of docetaxel. Conclusion: The growth inhibition of A549 human tumor cells by BisBAL NP and CPC was cumulative as of 1 µM. The BisBAL NP/CPC combination may constitute an innovative and cost-effective alternative for treating human lung cancer

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
