Saudi Arabia’s Council of Ministers approved an ambitious National Transformation Programme (NTP) in June 2016 with the aim of carrying out a complete restructuring of the economy. The implementation of Vision 2030 has major implications for the structure of Saudi Arabia’s labour market with the creation of 1.2 million non-oil private sector jobs, most of which are expected to be taken up by citizens. Official data shows the labour market has a number of distinctive features which will challenge the implementation of Vision 2030: an overreliance on expatriate labour; a preference by nationals for public sector jobs; a gender imbalance; persisting structural unemployment and problems in balancing labour supply and demand. The government is attempting to change the operation and structure of the labour market by a set of policies involving quotas, subsidies, taxes, penalties and the provision of information services, but for a number of reasons change is unlikely to proceed smoothly in the next few years.

There is a view that increasing inequalities in advanced economies are responsible for growth problems and political polarisation. A new impetus has been injected into the analysis of macroeconomic income distribution since if capital’s share is rising this has implications for the personal distribution of income. An international comparison of data from advanced countries does not reveal any widespread or consistent decrease in labour’s share for the past quarter of a century. No pattern is discernible and a number of statistical limitations and data issues need to be taken into account when interpreting the functional distribution of income.

It is likely to be several decades before data on government assets, off-balance sheet and contingent liabilities are consistently available across a wide range of countries. In the absence of data, GDP is a readily available scaling factor, but official sector agencies such as the IMF and private sector analysts recognise the insufficiency of debt–GDP ratios. Some commentators claim that, using international standards, Greek government debt could be only around 75% of GDP, compared with official figures of around 180%. Fundamentally, such discrepancies reflects debt valuation variations related to the difference between market risk and credit risk.

Rare Earth Element Reserves are estimated at 130 million metric tons while global production/processing capacity was approximately 126,000 metric tons in 2016, 95% controlled by China The US authorities and academics mistakenly treat Rare Earth Elements as “one group, one product”, but final high-tech products only use the appropriate elements providing desired characteristics. Disaggregation reveals that the U.S, the EU’s and Japan’s economies and national securities are 100% dependent on 30% of the naturally occurring elements on the Periodic Table of Elements and Chemistry. A comparative review between 1980 and today shows that the conditions are in place which will lead to the manipulation of the Rare Earth Elements market by the dominant player, China.

Despite broad public concern with the effect of offshoring on inequality, there is scant research. The authors shift the focus to the effect of offshoring on the labour share in value added. Regression analysis for a sample of 14 OECD countries in 21 manufacturing sectors covering the period 1995 to 2008 reveals that the effects of offshoring on the labour share are negative. They also show that different policy regimes with regard to labour markets, education and innovation, and trade liberalisation mediate these effects whilst contrasting the experiences of Germany and the U.S. where the manufacturing labour share decline was particularly strong.

This paper analyses Chinese property market data to evaluate recent trends in the market and to make prognoses for the future. It considers whether or not the existence of high prices and at the same time an enormous rise in residential supply in terms of floor space under construction means that there is a ``bubble'' in China's property market which may burst, similar to what happened in Japan in the early 1990s. Evidence that the price of new homes moves almost perfectly with sales of new residential floor space rather than with completed floor space suggests that the housing market is behaving normally and follows mini boom and bust cycles like other industries. The analysis finds that there are low maintenance costs for buyers after purchase due to the lack of annual property tax and negligible depreciation of bare-shelled housing units which limits the risk of default. Although recently developers are under pressure to raise more revenue mainly due to high interest-rate borrowing from shadow banks, the author considers that the probability of a systemic collapse of housing market is minimal given existing taxation systems, easing monetary policy and the continuing urbanization process.

Analysis of labour market performance using individual level data can reach radically different conclusions to those provided by a household-based analysis, using the same source of information. In Britain and other OECD countries the number of households without access to earned income has grown despite rising employment rates. Built around a comparison of the actual jobless rate in households with that which would occur if work were randomly distributed, the authors show that work is becoming increasingly polarised in many countries.
Changing household structure can only account for a minority of the rise in workless households, so that labour market failure is the dominant explanation. Polarisation of work will have important welfare and budgetary consequences for any country.

One answer to the question "How Rich are We?" is to compare levels of National Income either across countries or for a single country over time. However, the relevance of this approach depends on how accurately National Income measures the output of goods and services of a country. While it is difficult to measure, the Black Economy represents the output of goods and services that is not generally captured in the National Income Accounts. This article discusses the problems of measuring the size of the Black Economy and speculates on the questions of who is involved and how. The relative importance of Tax Evasion versus Benefit Fraud is discussed.
