Revealed cardinal preference
Get PDFI prove that as long as we allow the marginal utility for money (lambda) to
vary between purchases (similarly to the budget) then the quasi-linear and
the ordinal budget-constrained models rationalize the same data. However, we know that lambda is approximately constant. I provide a simple constructive proof for the necessary and sufficient condition for the constant lambda rationalization, which I argue should replace the Generalized Axiom of
Revealed Preference in empirical studies of consumer behavior.
'Go Cardinals!'
It is the minimal requirement of any scientifi c theory that it is consistent with
the data it is trying to explain. In the case of (Hicksian) consumer theory it was
revealed preference -introduced by Samuelson (1938,1948) - that provided an
empirical test to satisfy this need. At that time most of economic reasoning was
done in terms of a competitive general equilibrium, a concept abstract enough
so that it can be built on the ordinal preferences over baskets of goods - even if
the extremely specialized ones of Arrow and Debreu. However, starting in the
sixties, economics has moved beyond the 'invisible hand' explanation of how
-even competitive- markets operate. A seemingly unavoidable step of this
'revolution' was that ever since, most economic research has been carried out
in a partial equilibrium context. Now, the partial equilibrium approach does
not mean that the rest of the markets are ignored, rather that they are held
constant. In other words, there is a special commodity -call it money - that
reflects the trade-offs of moving purchasing power across markets. As a result,
the basic building block of consumer behavior in partial equilibrium is no longer
the consumer's preferences over goods, rather her valuation of them, in terms
of money. This new paradigm necessitates a new theory of revealed preference
Market Familiarity and the Location of South and North MNEs
Get PDFWe use a systematic empirical analysis of the determinants of South-South (SS) and North-South (NS) foreign direct
investment (FDI) as a canvas to explore how multinational enterprises’ (MNEs) location decisions are shaped by better
acquaintance with a foreign market resulting from bilateral ties, experience of international expansion, and knowledge of
how to deal with poor governance. We find that these various aspects of market familiarity, which can interact together,
are important to explain and differentiate the location behaviours of South MNEs (S-MNEs) and North MNEs (N-MNEs)
in developing countries
The system-wide impacts of the external benefits to higher education on the Scottish economy: An exploratory “micro-to-macro” approach
Get PDFThe private market benefits of education, i.e. the wage premia of graduates, are widely studied at the micro level, although the magnitude of their macroeconomic impact is disputed. However, there are additional benefits of education, which are less well understood but could potentially drive significant macroeconomic impacts. Following the taxonomy of McMahon (2009) we identify four different types of benefits of education. These are: private market benefits (wage premia); private non market benefits (own health, happiness, etc.); external market benefits (productivity spillovers; and external non-market benefits (crime rates, civic society, democratisation, etc.). Drawing on available microeconometric evidence we use a micro-to-macro simulation approach (Hermannsson et al, 2010) to estimate the macroeconomic impacts of external benefits of higher education. We explore four cases: technology spillovers from HEIs; productivity spillovers from more skilled workers in the labour market; reduction in property crime; and the potential overall impact of external and private non-market benefits. Our results suggest that the external economic benefits of higher education could potentially be very large. However, given the dearth of microeconomic evidence this result should be seen as tentative. Our aim is to illustrate the links from education to the wider economy in principle and encourage further research in the field
The determinants of sovereign bond yield spreads in the EMU
Get PDFWe use a panel of euro area countries to assess the determinants of long-term sovereign bond yield spreads over the period 1999.01-2010.12. We find that, unlike the period preceding the global financial crisis, European government bond yield spreads are wellexplained by macro- and fiscal fundamentals over the crisis period. We also find that the menu of macro and fiscal risks priced by markets has been significantly enriched since March 2009, including the risk of the crisis’ transmission among EMU member states, international risk and liquidity risk. Finally, we find that sovereign credit ratings
are statistically significant in explaining spreads, yet compared to macro- and fiscal fundamentals their role is limited
Marx: From Hegel and Feuerbach to Adam Smith
Get PDFThis paper discusses the development of Marx’s thought over a period of something like fifteen months, between the spring of 1843 and the autumn of 1844. The focus of the paper is Marx’s first encounter with classical political economy as he found it in the Wealth of Nations. The outcome of this encounter was presented by Marx in his Economic and Philosophical Manuscripts of 1844. It is argued here that in the classical theory, with which he had hitherto been largely unfamiliar, Marx found all the elements he needed to synthesise the philosophical standpoint he had developed in the preceding months with political economy. The Manuscripts represent the first crucial stage in the development of this synthesis. This first encounter of Marx with classical political economy, and his first steps in the development of his synthesis, have received hardly any attention in the literature. The present paper seeks to fill this gap
Why do UK banks securitize?
Get PDFThe eight years from 2000 to 2008 saw a rapid growth in the use of securitization by UK banks. We aim to identify the reasons that contributed to this rapid growth. The time period (2000 to 2010) covered by our study is noteworthy as it covers the pre- financial crisis credit-boom, the peak of the fi nancial crisis and its aftermath. In the wake of the financial crisis,
many governments, regulators and political commentators have pointed an accusing finger at the securitization market - even in the absence of a detailed statistical and economic analysis.
We contribute to the extant literature by performing such an analysis on UK banks, focussing principally on whether it is the need for liquidity (i.e. the funding of their balance sheets), or the desire to engage in regulatory capital arbitrage or the need for credit risk transfer that has led to UK banks securitizing their assets.
We show that securitization has been signi ficantly driven by liquidity reasons. In addition, we observe a positive link between securitization and banks credit risk. We interpret these latter findings as evidence that UK banks which engaged in securitization did so, in part, to
transfer credit risk and that, in comparison to UK banks which did not use securitization, they had more credit risk to transfer in the sense that they originated lower quality loans and held lower quality assets. We show that banks which issued more asset-backed securities before the
financial crisis suffered more defaults after the financial crisis
Employment Protection, Flexibility and Firms’ Strategic Location Decisions under Uncertainty
Get PDFWe construct a model in which oligopolistic firms decide between locating
in a country where employment protection implies costly output adjustments and in
one without employment protection. Using a two-period three-stage game with
uncertainty, we demonstrate that location is influenced by both flexibility and
strategic concerns. The strategic effects under Cournot work towards domestic
anchorage in the country with employment protection while those under Bertrand do
not. Strategic agglomeration can occur in the inflexible country under Cournot and
even under Bertrand, provided uncertainty and foreign direct investment costs are
low
Forward Looking and Myopic Regional Computable General Equilibrium Models. How Significant is the Distinction?
Get PDFWe present a stylized intertemporal forward-looking model able that accommodates key regional economic features, an area where the literature is not well developed. The main difference, from the standard applications, is the role of saving and its implication for the balance of payments. Though maintaining dynamic forward-looking behaviour for agents, the rate of private saving is exogenously determined and so no neoclassical financial adjustment is needed. Also, we focus on the similarities and the differences between myopic and forward-looking models, highlighting the divergences among the main adjustment equations and the resulting simulation outcomes
The regional economic impacts of biofuels: A review of multisectoral modelling techniques and evaluation of applications
Get PDFThe regional economic impact of biofuel production depends upon a number of interrelated factors: the specific biofuels feedstock and production technology employed; the sector’s embeddedness to the rest of the economy, through its demand for local resources; the extent to which new activity is created. These issues can be analysed using multisectoral economic models. Some studies have used (fixed price) Input-Output (IO) and Social Accounting Matrix (SAM) modelling frameworks, whilst a nascent Computable General Equilibrium (CGE) literature has also begun to examine the regional (and national) impact of biofuel development. This paper reviews, compares and evaluates these approaches for modelling the regional economic impacts of biofuels
Social Housing Policies in Latin America and Singapore: Lessons for China
Get PDFThis paper addresses the challenges facing China in accelerating the pace of rural-urban migration as part of its on-going economic development programme. It explains the push and pull influences on migration and in particular explains why a continuing focus on urbanisation is justified by the very large gap between rural and urban incomes and the relatively higher income elasticity of demand for urban-based goods and services. The provision of affordable housing is an integral part of this structural shift programme. The paper thus considers the most appropriate ways in which housing finance can be mobilised, and thence how both the quality and the affordability of the housing stock can be increased. Positive and negative lessons for China are offered from the different urbanisation experiences of Latin America (especially Colombia) and Singapore
