The South African Informal Sector - Providing Jobs, Reducing Poverty (Paperback): Frederick Fourie The South African Informal Sector - Providing Jobs, Reducing Poverty (Paperback)
Frederick Fourie
R290 R249 Discovery Miles 2 490 Save R41 (14%) Ships in 5 - 10 working days

Although South Africa’s informal sector is small compared to other developing countries, it nevertheless provides livelihoods, employment and income for millions of workers and business owners. Almost half of informal-sector workers work in firms with employees. The annual entry of new enterprises is quite high, as is the number of informal enterprises that grow their employment. There is no shortage of entrepreneurship and desire to grow.

However, obstacles and constraints cause hardship and failure, pointing to the need for well-designed policies to enable and support the sector, rather than suppress it. The same goes for formalisation. Recognising the informal sector as an integral part of the economy, rather than ignoring it, is a crucial first step towards instituting a ‘smart’ policy approach.

The South African Informal Sector is strongly evidence- and data-driven, with substantial quantitative contributions combined with qualitative findings – suitable for an era of increased pressure for evidence-based policy-making – and utilises several disciplinary perspectives.

'If you aren't in love with stats before reading this book, you will be by the time you're done. Powerful, persuasive, and in these truth-defying times, indispensable' Caroline Criado Perez, author of Invisible Women 'Fabulously readable, lucid, witty and authoritative . . . Every politician and journalist should be made to read this book, but everyone else will get so much pleasure and draw so much strength from the joyful way it dispels the clouds of deceit and delusion' Stephen Fry When was the last time you read a grand statement, accompanied by a large number, and wondered whether it could really be true? Statistics are vital in helping us tell stories - we see them in the papers, on social media, and we hear them used in everyday conversation - and yet we doubt them more than ever. But numbers - in the right hands - have the power to change the world for the better. Contrary to popular belief, good statistics are not a trick, although they are a kind of magic. Good statistics are not smoke and mirrors; in fact, they help us see more clearly. Good statistics are like a telescope for an astronomer, a microscope for a bacteriologist, or an X-ray for a radiologist. If we are willing to let them, good statistics help us see things about the world around us and about ourselves - both large and small - that we would not be able to see in any other way. In How to Make the World Add Up, Tim Harford draws on his experience as both an economist and presenter of the BBC's radio show 'More or Less'. He takes us deep into the world of disinformation and obfuscation, bad research and misplaced motivation to find those priceless jewels of data and analysis that make communicating with numbers worthwhile. Harford's characters range from the art forger who conned the Nazis to the stripper who fell in love with the most powerful congressman in Washington, to famous data detectives such as John Maynard Keynes, Daniel Kahneman and Florence Nightingale. He reveals how we can evaluate the claims that surround us with confidence, curiosity and a healthy level of scepticism. Using ten simple rules for understanding numbers - plus one golden rule - this extraordinarily insightful book shows how if we keep our wits about us, thinking carefully about the way numbers are sourced and presented, we can look around us and see with crystal clarity how the world adds up.

Capital And Ideology (Hardcover): Thomas Piketty Capital And Ideology (Hardcover)
Thomas Piketty; Translated by Arthur Goldhammer 1
R666 Discovery Miles 6 660 Ships in 7 - 10 working days

The epic successor to one of the most important books of the century: at once a retelling of global history, a scathing critique of contemporary politics, and a bold proposal for a new and fairer economic system.

Thomas Piketty’s bestselling Capital in the Twenty-First Century galvanized global debate about inequality. In this audacious follow-up, Piketty challenges us to revolutionize how we think about politics, ideology, and history. He exposes the ideas that have sustained inequality for the past millennium, reveals why the shallow politics of right and left are failing us today, and outlines the structure of a fairer economic system.

Our economy, Piketty observes, is not a natural fact. Markets, profits, and capital are all historical constructs that depend on choices. Piketty explores the material and ideological interactions of conflicting social groups that have given us slavery, serfdom, colonialism, communism, and hypercapitalism, shaping the lives of billions. He concludes that the great driver of human progress over the centuries has been the struggle for equality and education and not, as often argued, the assertion of property rights or the pursuit of stability. The new era of extreme inequality that has derailed that progress since the 1980s, he shows, is partly a reaction against communism, but it is also the fruit of ignorance, intellectual specialization, and our drift toward the dead-end politics of identity.

Once we understand this, we can begin to envision a more balanced approach to economics and politics. Piketty argues for a new “participatory” socialism, a system founded on an ideology of equality, social property, education, and the sharing of knowledge and power. Capital and Ideology is destined to be one of the indispensable books of our time, a work that will not only help us understand the world, but that will change it.

R1,509 Discovery Miles 15 090 Ships in 12 - 17 working days

Cluster analysis finds groups in data automatically. Most methods have been heuristic and leave open such central questions as: how many clusters are there? Which method should I use? How should I handle outliers? Classification assigns new observations to groups given previously classified observations, and also has open questions about parameter tuning, robustness and uncertainty assessment. This book frames cluster analysis and classification in terms of statistical models, thus yielding principled estimation, testing and prediction methods, and sound answers to the central questions. It builds the basic ideas in an accessible but rigorous way, with extensive data examples and R code; describes modern approaches to high-dimensional data and networks; and explains such recent advances as Bayesian regularization, non-Gaussian model-based clustering, cluster merging, variable selection, semi-supervised and robust classification, clustering of functional data, text and images, and co-clustering. Written for advanced undergraduates in data science, as well as researchers and practitioners, it assumes basic knowledge of multivariate calculus, linear algebra, probability and statistics.

Loss Coverage - Why Insurance Works Better with Some Adverse Selection (Paperback): Guy Thomas Loss Coverage - Why Insurance Works Better with Some Adverse Selection (Paperback)
Guy Thomas
R581 Discovery Miles 5 810 Ships in 12 - 17 working days

Most academic and policy commentary represents adverse selection as a severe problem in insurance, which should always be deprecated, avoided or minimised. This book gives a contrary view. It details the exaggeration of adverse selection in insurers' rhetoric and insurance economics, and presents evidence that in many insurance markets, adverse selection is weaker than most commentators suggest. A novel arithmetical argument shows that from a public policy perspective, 'weak' adverse selection can be a good thing. This is because a degree of adverse selection is needed to maximise 'loss coverage', the expected fraction of the population's losses which is compensated by insurance. This book will be valuable for those interested in public policy arguments about insurance and discrimination: academics (in economics, law and social policy), policymakers, actuaries, underwriters, disability activists, geneticists and other medical professionals.

Random Sets in Econometrics (Paperback): Ilya Molchanov, Francesca Molinari Random Sets in Econometrics (Paperback)
Ilya Molchanov, Francesca Molinari
R691 Discovery Miles 6 910 Ships in 12 - 17 working days

Random set theory is a fascinating branch of mathematics that amalgamates techniques from topology, convex geometry, and probability theory. Social scientists routinely conduct empirical work with data and modelling assumptions that reveal a set to which the parameter of interest belongs, but not its exact value. Random set theory provides a coherent mathematical framework to conduct identification analysis and statistical inference in this setting and has become a fundamental tool in econometrics and finance. This is the first book dedicated to the use of the theory in econometrics, written to be accessible for readers without a background in pure mathematics. Molchanov and Molinari define the basics of the theory and illustrate the mathematical concepts by their application in the analysis of econometric models. The book includes sets of exercises to accompany each chapter as well as examples to help readers apply the theory effectively.
