The present article aims to examine the risk of host governments’ interference with the property of foreign investors (expropriation) in the petroleum industry. Host states have the police power to make regulatory changes. The ‘police power’ is defined as the inherent and plenary power of a sovereign to make all laws necessary and proper to preserve the public security, order, health, morality, and justice. It is a fundamental power essential to government, and it cannot be surrendered by the legislature or irrevocably transferred away from government. The government can interfere with the contract and change the contract terms or may even directly take the investment. This is the main reason for international petroleum disputes and international arbitration practice has addressed such risk. For this purpose, the concept of property and compensable property rights under international law are of great significance. Indeed, expropriation conveys a deprivation of a property owner of this property. This paper assesses the concept of expropriation, the international legal requirements for a lawful expropriation, and then, analyses the relevant international arbitral awards in petroleum jurisprudence.

People's work and personal life are not two separate categories, but a concept and should be considered together; because considering them separately causes us to have an incomplete understanding of both. Accordingly, the purpose of this study is to design a model for work-life balance of employees of the National Iranian Gas Company. The present research is applied in terms of orientation, descriptive in terms of purpose and survey in terms of strategy. In this study, using Delphi technique, the opinions of 15 experts on the factors affecting the balance of family work were identified based on the roadmap programs for reforming the administrative system of the country and 33 indicators. The sample size was 219 official employees and 61 contract employees of the official and contract employees of the National Iranian Gas Company (main company). Using confirmatory factor analysis, the mentioned dimensions were evaluated and tested. From the results of DEMETEL technique, it was observed that the factors related to monitoring, evaluation and development of organizational culture had the most relationship with other factors. The index of organizational culture development has the most impact and the factor of human capital has the least impact. The role and structure engineering index is the most influential in the next degree. Also, the criterion of factors related to management factors and technologies is very influential. The criterion of organizational culture development is also the least affected by other criteria. Engineering criteria role and structure have the highest impact and impact with other criteria studied. The criterion of human capital factors has the least impact with other variables. In this model, the criteria of engineering role and structure, development of organizational culture and monitoring and evaluation of the variable are causal and the rest are disabled.

Theories on the relationship between money and inflation had largely been shaped around the positive relationship and money causality for inflation before the Post-Keynesians. Since the 1980s, this idea emerged that there might be no correlation between money growth and inflation. In the case of existence, the causality is reversed, so money is endogenous somehow. However, practically there is a suspicion that the causality between money growth and inflation is not fixed and linear. According to the experience of Turkey in the last seven decades, which has experienced fluctuated inflation rates, it is supposed that the causal relationship between Broad Money Growth (BMG) and inflation is not constant. This paper examines this idea over 1961–2019 using a Markov Switching Vector Autoregressive model (MS-VAR), which allows for regime shifts. Findings show that the causal relationship between BMG and inflation has not been constant, and different regimes have generated different causality orientations. There was a one-way causality from inflation to BMG during 1971–2001 that inflation rates were high. Whereas, during 1961–70 and 2002–19, when the Turkish economy experienced milder inflation rates, there was a one-way causal relationship from BMG to inflation.

Liquid assets are critical for banking operations. They guarantee avoiding liquidity risk and widens managerial decision options to invest in emerging profitable projects; however, holding extra liquidity entails opportunity costs. Accordingly, empirical literature does not provide a conclusive relationship between liquidity and profitability. The purpose of this research is to analyze the asymmetric effects of holding liquid assets by commercial banks on their profitability. Parallel to a detailed review of contradicting theories and empirical evidence, we have developed an econometric model to capture the nonlinear effects of liquidity on performance. The proposed model is tested for a sample of seven listed Iranian commercial banks during 2006-2018 by Arellano-Bond dynamic panel-data estimation. We found that the nonlinear relationship, if any, is not an inverse U as Bordeleau and Graham (2010) suggested. Results show a positive (holding more liquid assets increases the profitability of Iranian banks), and even an accelerating effect for liquidity, likely due to the low level of liquid assets maintained by Iranian banks.

Information and communication technology (ICT) has been rapidly developed in the last two decades and has directly or indirectly affected most areas of human life, including health, which is also referred to as e-health. On the other hand, in the past three decades, most countries in the world have experienced rapid growth in health expenditures, as health expenditures have become one of the most important items of household expenditure. Besides, in developing countries, including Iran, the main financial burden of using health goods and services is borne by households. Reducing the financial burden of health services on households has been one of the long-standing goals of policymakers. It seems that using the ICT capabilities in the form of e-health can be one of the effective solutions in this regard. The present study seeks to investigate this issue. For model estimation, the panel data method and the GLS model in the form of provincial data were applied. The results imply that besides other factors affecting the household health expenditures (such as income, education level, insurance coverage level, etc.), the development of ICT managed to have a significant effect on reducing the health expenditures. It seems developing ICT infrastructure, expanding its penetration rate and developing its applications in the form of e-health can be considered as a proper strategy in the field of health care.

Financial markets are channels for attracting surplus financial resources and allocating them to investment. Macro-prudential policy needs to consider financial cycle in order to assess the state of the financial sector, predict its developments and justify the need for specific policy tools. we examined the effect of macro-prudential policies on financial cycle of Iran's economy Over the period 2008-2018 using Unobserved Components Structural Time Series Model. We explored the effect of macro-prudential policy index and other variables on the financial cycle. The findings of this study, using the Generalized method of moments (GMM) for the time series data, suggested that the macro-prudential policy index has a negative and significant effect on the financial cycle in the Iranian economy. Also, the probability(likelihood) of a banking crisis, the interbank market loan rate and the economic growth index have positive and significant effect on the financial cycle.
