A Treatise on the Family. G. S. Becker. Cambridge, MA: Harvard University Press. 1981. Gary Becker is one of the most famous and influential economists of the second half of the 20th century, a fervent contributor to and expounder of the University of Chicago free-market philosophy, and winner of the 1992 Nobel Prize in economics. Although any book with the word "treatise" in its title is clearly intended to have an impact, one coming from someone as brilliant and controversial as Becker certainly had such a lofty goal. It has received many article-length reviews in several disciplines (Ben-Porath, 1982; Bergmann, 1995; Foster, 1993; Hannan, 1982), which is one measure of its scholarly importance, and yet its impact is, I think, less than it may have initially appeared, especially for scholars with substantive interests in the family. This book is, its title notwithstanding, more about economics and the economic approach to behavior than about the family. In the first sentence of the preface, Becker writes "In this book, I develop an economic or rational choice approach to the family." Lest anyone accuse him of focusing on traditional (i.e., material) economics topics, such as family income, poverty, and labor supply, he immediately emphasizes that those topics are not his focus. "My intent is more ambitious: to analyze marriage, births, divorce, division of labor in households, prestige, and other non-material behavior with the tools and framework developed for material behavior." Indeed, the book includes chapters on many of these issues. One chapter examines the principles of the efficient division of labor in households, three analyze marriage and divorce, three analyze various child-related issues (fertility and intergenerational mobility), and others focus on broader family issues, such as intrafamily resource allocation. His analysis is not, he believes, constrained by time or place. His intention is "to present a comprehensive analysis that is applicable, at least in part, to families in the past as well as the present, in primitive as well as modern societies, and in Eastern as well as Western cultures." His tone is profoundly conservative and utterly skeptical of any constructive role for government programs. There is a clear sense of how much better things were in the old days of a genderbased division of labor and low market-work rates for married women. Indeed, Becker is ready and able to show in Chapter 2 that such a state of affairs was efficient and induced not by market or societal discrimination (although he allows that it might exist) but by small underlying household productivity differences that arise primarily from what he refers to as "complementarities" between caring for young children while carrying another to term. Most family scholars would probably find that an unconvincingly simple explanation for a profound and complex phenomenon. What, then, is the salient contribution of Treatise on the Family? It is not literally the idea that economics could be applied to the nonmarket sector and to family life because Becker had already established that with considerable success and influence. At its core, microeconomics is simple, characterized by a belief in the importance of prices and markets, the role of self-interested or rational behavior, and, somewhat less centrally, the stability of preferences. It was Becker's singular and invaluable contribution to appreciate that the behaviors potentially amenable to the economic approach were not limited to phenomenon with explicit monetary prices and formal markets. Indeed, during the late 1950s and throughout the 1960s, he did undeniably important and pioneering work extending the domain of economics to such topics as labor market discrimination, fertility, crime, human capital, household production, and the allocation of time. Nor is Becker's contribution the detailed analyses themselves. Many of them are, frankly, odd, idiosyncratic, and off-putting. …

In this book, Andrew Harvey sets out to provide a unified and comprehensive theory of structural time series models. Unlike the traditional ARIMA models, structural time series models consist explicitly of unobserved components, such as trends and seasonals, which have a direct interpretation. As a result the model selection methodology associated with structural models is much closer to econometric methodology. The link with econometrics is made even closer by the natural way in which the models can be extended to include explanatory variables and to cope with multivariate time series. From the technical point of view, state space models and the Kalman filter play a key role in the statistical treatment of structural time series models. The book includes a detailed treatment of the Kalman filter. This technique was originally developed in control engineering, but is becoming increasingly important in fields such as economics and operations research. This book is concerned primarily with modelling economic and social time series, and with addressing the special problems which the treatment of such series poses. The properties of the models and the methodological techniques used to select them are illustrated with various applications. These range from the modellling of trends and cycles in US macroeconomic time series to to an evaluation of the effects of seat belt legislation in the UK.

Forecasting, Structural Time Series Models and the Kalman Filter

We investigate whether income inequality affects subsequent growth in a cross-country sample for 1965-90, using the models of Barro (1997), Bleaney and Nishiyama (2002) and Sachs and Warner (1997), with negative results. We then investigate the evolution of income inequality over the same period and its correlation with growth. The dominating feature is inequality convergence across countries. This convergence has been significantly faster amongst developed countries. Growth does not appear to influence the evolution of inequality over time. Outline

Economic growth and income inequality

Poverty from a Nonmonetary Perspective

Up to 80 percent of the labour force in low-income countries works in agri-food, mostly on the farm. In high-income countries, the proportion is still about 10 percent, more than half of them off the farm in related food industry and services, and many, migrant workers. Unsurprisingly, much hope is pinned on the agri-food system to tackle the global challenges of good-job creation and poverty reduction.

What is the future of work in agri-food?

Perceptions of Africa have changed dramatically. Viewed as a continent of wars, famines and entrenched poverty in the late 1990s, there is now a focus on “Africa rising” and an “African 21st century.” Two decades of unprecedented economic growth in Africa should have brought substantial improvements in well-being. Whether or not they did, remains unclear given the poor quality of the data, the nature of the growth process (especially the role of natural resources), conflicts that affect part of the region, and high population growth. Poverty in a Rising Africa documents the data challenges and systematically reviews the evidence on poverty from monetary and nonmonetary perspectives, as well as a focus on dimensions of inequality. Chapter 1 maps out the availability and quality of the data needed to track monetary poverty, reflects on the governance and political processes that underpin the current situation with respect to data production, and describes some approaches to addressing the data gaps. Chapter 2 evaluates the robustness of the estimates of poverty in Africa. It concludes that poverty reduction in Africa may be slightly greater than traditional estimates suggest, although even the most optimistic estimates of poverty reduction imply that more people lived in poverty in 2012 than in 1990. A broad-stroke profile of poverty and trends in poverty in the region is presented. Chapter 3 broadens the view of poverty by considering nonmonetary dimensions of well-being, such as education, health, and freedom, using Sen's (1985) capabilities and functioning approach. While progress has been made in a number of these areas, levels remain stubbornly low. Chapter 4 reviews the evidence on inequality in Africa. It looks not only at patterns of monetary inequality in Africa but also other dimensions, including inequality of opportunity, intergenerational mobility in occupation and education, and extreme wealth in Africa.

Asset ownership indices are widely used as inexpensive proxies for consumption. This paper shows that these indices can be augmented using dichotomous indicators for consumption, which are equally easy to obtain. The paper uses multiple rounds of Living Standards Measurement Study surveys from Malawi, Uganda, Rwanda, Tanzania, and Ghana to construct indices with different item subcategories and performs a meta-analysis comparing the indices to per capita consumption. The results show that the standard asset indices, which are derived from durable ownership and housing characteristic indicators, perform well in urban settings. Yet, in rural samples and when identifying the extreme poor, household rankings and poverty classification accuracy can be meaningfully improved by adding indicators of food and semi-durable consumption. The study finds small improvement from using national weights in urban samples but no improvement from using alternative construction methods. With most of Africa?s poor concentrated in rural areas, these are important insights.

The Performance of a Consumption Augmented Asset Index in Ranking Households and Identifying the Poor

A thriving region until the early 1990s, Slavonia, the eastern region of Croatia, has been confronted with stagnation and decline, ageing and outmigration as well as impoverishment ever since. This followed Croatia's homeland war of 1991-1995, with Slavonia one of the frontlines, economic restructuring of its state-led economy during the 1990s and 2000s and the global economic crisis of the late 2000s. More recently, after Croatia's EU accession in 2013 and coinciding with the economic upswing since 2014 in Croatia and the EU, Slavonia's labor market has started to tighten, with registered vacancies now exceeding the number of job seekers for highly educated as well as some unskilled and semi-skilled occupations. However, inactivity and unemployment remain high. In 2017, the share of the working-age population in work was only 51 percent, 10 percentage points below the rest of Croatia (61 percent) and 17 percentage points below the 2017 EU28 average. A legacy of war, limited availability of care services, and especially lower education levels explain an important part of Slavonia's much higher inactivity and unemployment. On the demand side, labor productivity in Slavonia's firms is systematically lower than in the rest of the country (except in agriculture and forestry), also consistent with Slavonia's sizeablewage gap. This, together with general disenchantment of the Slavonian population with the economicand business environment, has prompted outmigration. At the same time, a small number of firms alsooutperform their sectoral competitors elsewhere in Croatia, signaling Slavonia's potential.Looking ahead, private sector job creation remains a top priority, especially focusing on Slavonia's lower educated, who make up the bulk of the unemployed and inactive. This especially requires a reduction in the regulatory burden and an increase in Slavonian firms' competitiveness, which will also help to close the substantial wage gap with the rest of Croatia. Given the large share of its population in agriculture and forestry-related activities (close to 30 percent), Program Slavonia's current focus on agriculture and forestry is clearly warranted. With Slavonia's longstanding history and labor force experience in manufacturing and the rising number of vacancies in this sector, so is attention to manufacturing.
