Oil Exports and the Iranian Economy

This paper develops a long run growth model for a major oil exporting economy and derives conditions under which oil revenues are likely to have a lasting impact. This approach contrasts with the standard literature on the "Dutch disease" and the "resource curse", which primarily focus on short run implications of a temporary resource discovery. Under certain regularity conditions and assuming a Cobb Douglas production function, it is shown that (log) oil exports enter the long run output equation with a coefficient equal to the share of capital. The long run theory is tested using a new quarterly data set on the Iranian economy over the period 1979Q1-2006Q4. Building an error correction specification in real output, real money balances, inflation, real exchange rate, oil exports, and foreign real output, the paper finds clear evidence for two long run relations: an output equation as predicted by the theory and a standard real money demand equation with inflation acting as a proxy for the (missing) market interest rate. Real output in the long run is shaped by oil exports through their impact on capital accumulation, and the foreign output as the main channel of technological transfer. The results also show a significant negative long run association between inflation and real GDP, which is suggestive of economic inefficiencies. Once the effects of oil exports are taken into account, the estimates support output growth convergence between Iran and the rest of the world. We also find that the Iranian economy adjusts quite quickly to the shocks in foreign output and oil exports, which could be partly due to the relatively underdeveloped nature of Iran’s financial markets

Compilation, Revision and Updating of the Global VAR (GVAR) Database, 1979Q2-2019Q4

This is the latest version of the Global VAR (GVAR) dataset. The GVAR is a global modelling framework for analyzing the international macroeconomic transmission of shocks, taking into account drivers of economic activity, interlinkages and spillovers between different countries, and the effects of unobserved or observed common factors. This dataset includes quarterly macroeconomic variables for 33 economies (log real GDP, y, the rate of inflation, dp, short-term interest rate, r, long-term interest rate, lr, the log deflated exchange rate, ep, and log real equity prices, eq), as well as quarterly data on commodity prices (oil prices, poil, agricultural raw material, pmat, and metals prices, pmetal), over the 1979Q2 to 2019Q4 period. These 33 countries cover more than 90% of world GDP.

Cross-sectional study among medical students in Latvia: Differences of mental symptoms and somatic symptoms among Latvian and international students

Introduction. This research aims to determine the prevalence of mental symptoms (depressive symptoms, anxiety and adjustment disorders) and somatic symptoms among medical students at Riga Stradins University in Latvia, as well as to display the differences between local and international medical students. Methods. A cross-sectional study was conducted by means of onlinebased questionnaires among medical students in their 1st, 4th and 6th years studying in Riga, Latvia, during March 2017. The mental and somatic symptoms were screened with the PHQ-D Option C (PHQ-15, PHQ-9, GAD-7). Symptoms of adjustment disorder were obtained by the ADNM-6. Medical students were divided into three groups according to their answers of the PHQ-D: Group A: no symptom, group B: a single symptom, group C: multiple symptoms. A general questionnaire and a questionnaire regarding stressful life events over the past half-year were distributed additionally. Results. 67 (40.1%) participants were Latvian students; 100 (59.9%) were international students. 23 (34.3%) Latvian students were in group A, 20 (29.9%) in group B, 24 (35.8%) in group C. 51 (51%) international students were in group A, 34 (34%) in group B, 14 (14%) in group C. Latvians displayed statisti cally significantly more health-related symptoms (0.003). 11 (11%) international students who reported a stressful life event over the last half-year were in group C. 21 (31.3%) of Latvian students who reported a stressful life event over the last half-year were in group C. 73 (43.7%) of all students had experienced stressful life events and displayed troubles adjusting to them. 65 (63.1%) students of the two groups with a stressful life found the event to have a great burden on them, 63 (61.2%) were wondering whether it could happen again, and 73 (70.9%) tried to suppress their feelings. Conclusion. Medical students in Latvia have a high prevalence of healthrelated symptoms. Latvian medical students display more health-related symptoms and symptoms of adjustment disorder. Further research needs to be performed to investigate whether Latvians have a lower threshold for stressors or whether they are exposed to more stressors than international students. The high prevalence of symptoms of adjustment disorder may impact the prospective patient-doctor relationship and the treatment outcome

One Hundred Years of Oil Income and the Iranian Economy: A Curse or a Blessing

This paper examines the impact of oil revenues on the Iranian economy over the past hundred years, spanning the period 1908-2010. It is shown that although oil has been produced in Iran over a very long period, its importance in the Iranian economy was relatively small up until the early 1960s. It is argued that oil income has been both a blessing and a curse. Oil revenues when managed appropriately are a blessing, but their volatility (which in Iran is much higher than oil price volatility) can have adverse effects on real output, through excessively high and persistent levels of inflation. Lack of appropriate institutions and policy mechanisms which act as shock absorbers in the face of high levels of oil revenue volatility have also become a drag on real output. In order to promote growth, policies should be devised to control inflation; to serve as shock absorbers negating the adverse effects of oil revenue volatility; to reduce rent seeking activities; and to prevent excessive dependence of government finances on oil income

Projection-Free Non-Smooth Convex Programming

In this paper, we provide a sub-gradient based algorithm to solve general constrained convex optimization without taking projections onto the domain set. The well studied Frank-Wolfe type algorithms also avoid projections. However, they are only designed to handle smooth objective functions. The proposed algorithm treats both smooth and non-smooth problems and achieves an $O(1/\sqrt{T})$ convergence rate (which matches existing lower bounds). The algorithm yields similar performance in expectation when the deterministic sub-gradients are replaced by stochastic sub-gradients. Thus, the proposed algorithm is a projection-free alternative to the Projected sub-Gradient Descent (PGD) and Stochastic projected sub-Gradient Descent (SGD) algorithms
