<p>The paper shows how analyses assuming perfect competition can yield a distorted estimation of the expected effects of a trade liberalization when market imperfections exist. The analytical framework adopted is very simple and three extreme imperfect market structures are considered. In the first case, the exporting country maximizes its producer and consumer surplus by intervening in the world market. The second market imperfection considered is the existence of a private firm playing the role of «pure middleman» in the world market. Then the case of a producer-owned marketing board which is granted exclusive export authority is addressed. It is shown that estimates of the impact of a tariff reduction in terms of prices and volume traded obtained assuming perfect competition when this postulate does not hold, are distorted. When domestic demand and supply functions are assumed to be linear, the impact is overestimated; a ranking of the size of such distortions in the three cases analyzed is provided. When no restriction is imposed on the demand and supply functions, the error in the estimated impact of a tariff reduction involves the magnitude as well as the sign of the expected changes in prices and volume traded. Finally, it is proved that when a private firm exerts monopoly and monopsony power in the world market, both the importing and the exporting countries may well be better off if, rather than making a move towards trade liberalization, the importing country «compensates» the exporting country by means of a direct transfer.</p>

BACKGROUND Covid-19 is an emerging infectious disease like viral zoonosis caused by new coronavirus SARS CoV 2. On December 31, 2019, Wuhan Municipal Health Commission in Hubei province (China) reported cases of pneumonia, the origin of which is a new coronavirus. Rapidly extendable around the world, the World Health Organization (WHO) declares it pandemic on March 11, 2020. This pandemic reaches Algeria on February 25, 2020, date on which the Algerian minister of health, announced the first case of Covid-19, a foreign citizen. From March 1, a cluster is formed in Blida and becomes the epicentre of the coronavirus epidemic in Algeria, its total quarantine is established on March 24, 2020, it will be smoothly alleviated on April 24. A therapeutic protocol based on hydroxychloroquine and azithromycin was put in place on March 23, for complicated cases, it was extended to all the cases confirmed on April 06. OBJECTIVE This study aimed to demonstrate the effectiveness of hydroxychloroquin/azithromycin protocol in Algeria, in particular after its extension to all patients diagnosed COVID-19 positive on RT-PCR test. We were able to illustrate this fact graphically, but not to prove it statistically because the design of our study, indeed in the 7 days which followed generalization of therapeutic protocol, case fatality rate decrease and doubling time increase, thus confirming the impact of wide and early prescription of hydroxychloroquin/azithromycin protocol. METHODS We have analyzed the data collected from press releases and follow-ups published daily by the Ministry of Health, we have studied the possible correlations of these data with certain events or decisions having a possible impact on their development, such as confinement at home and its reduction, the prescription of hydroxychloroquine/azithromycin combination for serious patients and its extension to all positive COVID subjects. Results are presented in graphics, the data collection was closed on 31/05/2020. RESULTS Covid-19 pandemic spreads from February 25, 2020, when a foreign citizen is tested positive, on March 1 a cluster is formed in the city of Blida where sixteen members of the same family are infected during a wedding party. Wilaya of Blida becomes the epicentre of coronavirus epidemic in Algeria and lockdown measures taken, while the number of national cases diagnosed begins to increases In any event, the association of early containment measures combined with a generalized initial treatment for all positive cases, whatever their degree of severity, will have contributed to a reduction in the fatality rate of COVID 19 and a slowing down of its doubling time. CONCLUSIONS In Algeria, the rapid combination of rigorous containment measure at home and early generalized treatment with hydroxychloroquin have demonstrated their effectiveness in terms of morbidity and mortality, the classic measures of social distancing and hygiene will make it possible to perpetuate these results by reducing viral transmission, the only unknown, the reopening procedure which can only be started after being surrounded by precautions aimed at ensuring the understanding of the population.

The Impact

As the COVID-19 pandemic has spread across the world, the existence of disruptions in demand and supply have become more severe, conducted by containment measures taken by countries and affecting different sectors around the world. Although businesses and workplaces are restarting activities in some countries, with containment measures gradually being lifted, overall consumer demand is expected to remain low, also determined by the loss of jobs and income. Therefore, the scale of the impact on supply chains exceeded anything most companies had anticipated. This study aims to understand how companies were affected and identify some lessons learned about their vulnerabilities and the possible ways to address them in the long term. On the other hand, it is intended to reveal some of the impacts of COVID-19 and make some practical suggestions that can help in political and operational decisions to strengthen and build additional resilience in supply chains in the future.

The article reveals the essence and features of the development of the stock market in Ukraine. It was established that the vigorous activity of countries in the world financial markets means that they also face a risk of global financial turmoil (the so-called “domino effect”). It is determined that the impact of global financial instability on the country depends on the openness of its economy that will lead to significant external “shocks”. The possibility of providing effective influence on domestic stock market activity with taking into account the changing world situation, development of perfect trading strategies for each participant is substantiated. The conducted analysis of the world market conditions of stock markets in recent years has made it possible to assess the real risks for new participants in the stock market and become the basis for the development of an appropriate effective trading strategy. The practical significance of the results is that they allow for a measurable approach to assessing the existing risk when choosing one or another trading strategy to move to the world stock market.

The Impact

The world has experienced in recent years a rising anti-trade and anti-globalization sentiment, which would likely jeopardize recent efforts by the international trade community, in particular Members of the World Trade Organization (WTO), to promote multilateral trade liberalization (MTP). The current article investigates the impact of MTP on countries’ terms of trade volatility. Results based on a large panel dataset suggest that MTP exerts a significant reducing effect on countries’ terms of trade volatility. However, this impact appears to be dependent on countries’ development level. The take-home message is that greater cooperation on trade matters, including among WTO Members would help promote multilateral trade liberalization, which would surely contribute to reducing terms of trade volatility, for the benefits of all countries, in particular developing economies.

The Impact

The article terminates the author's series of publications on the impact of system of stereotypes of behaviour – "success formula" - on the development of phases of the life cycle of the socio-economic systems [7-11]. The author argues in favor of the view that lifecycle of any object of management is a complex spiral consisting of 10 phases, each of which, in turn, can be regarded as a separate life cycle. Because of the stereotypes of behaviour, prevailing during previous lifecycle phases, a change of lifecycle phases often leads to a crisis and is accompanied by painful correction of exchange proportions. The author motivates his conclusion that the modern economic crisis is caused by the distortion of exchange proportions. The indexes of changes in exchange proportions are proposed to use as an indicator of stability of the world market. Proposals on overcoming the crisis are made.
