During the 1980's, many European countries introduced flexibility measures in their labour market to fight high and persistent levels of unemployment. In particular, in many countries reforms consisted of the introduction of more flexible labour contracts (fixed-term contracts) in comparison to the predominant ones (permanent contracts). The purpose of this thesis is to analyse the effects of such contracts on the overall performance of the labour market. First, an economy with firing costs is analysed theoretically. Firing costs are generally considered one of the most important elements in making a labour market rigid. This chapter stresses the fact that it is not just the level of severance payments what matters, but a wider view of employment protection. In particular, dismissal conflicts are modeled explicitly and their cost is derived. In the second chapter, the effects on employment of introducing fixed-term contracts in an economy with only permanent contracts are analysed theoretically. Our findings are that higher employment at the expense of segmentation of the labour market only arises if wages are very flexible. Otherwise, employment is not necessarily higher than in a system with only permanent contracts. Moreover, from the social point of view, market segmentation is too large. The last two chapters are empirical work applied to Spain. The Spanish experience appears to be particularly useful in this context to draw some lessons of these policies because the unemployment rate is the highest among OECD economies despite the several "policy experiments" implemented in the last two decades. In Chapter 3 the duration pattern of fixed-term contracts and the determinants of the transformation of these into permanent ones are analysed. Evidence is found that fixed-term contracts are used as a screening device instrument. Also, employers use fixed-term contracts until their legal limit. In Chapter 4, we study the effects of fixed-term contracts on the duration distribution of unemployment. It is found that the chances of leaving unemployment for a reference group have increased at short durations, while they have decreased at long durations of unemployment.

This thesis examines the role of banks in influencing innovation and analyses their links to payment systems modernisation. The main argument is that banks are a type of technological institution having the potential to promote innovation, although such roles may be implicit or secondary. This role is investigated in eight chapters. The first three chapters review the major innovation models and progress in payment system. An analytical framework, based on evolutionary and resource-based views, is developed to examine how resources and routines which reflect an organisation's stock of skills, influence innovation, and assist them in sustaining competitive advantage. The following three chapters present the empirical results. In a survey of innovation in the banking industry, research results suggested that although there were relatively high levels of information technology awareness and application, particularly in payment system automation, there remained a moderate level of innovative capabilities among the banks studied. Further analysis through four mini case studies of the largest commercial banks also suggested similar increases in technological investments, but replication rates were also relatively high. Thus, it is argued that such investments may gain, but not sustain, competitive advantage, whereby the latter requires banks to innovate by acquiring, accumulating, and advancing their stock of skills. In this respect, the role of the central bank in creating a conducive environment for innovation is also important which may be seen through its involvement in payment systems modernisation. The final two chapters discuss the policy and research implications. It is argued that central bank policies oriented towards payment system reform, along with new payment product and services development by commercial banks, have come to play an important part in promoting technological innovation in banking. Such roles in reforming rudimentary payment systems have helped strengthen national information infrastructures, especially in emerging market economies, and moreover, have influenced the set-up of a national innovation system in banking which underpins economic development.

This thesis builds on the established body of research into the suitability of a country joining other countries in a monetary union by focusing on the potential costs resulting from the loss of monetary policy independence that is a corollary to forming a monetary union. We continue in the tradition of several other authors by extracting supply and demand shocks for a range of countries from VAR analysis and comparing the symmetry of these economic shocks between potential members of a monetary union. The theoretical contribution of this thesis is that we explicitly incorporate the size of each potential currency union member in the analysis. This contribution is motivated by the observation that a large country would be a more significant part of a given currency union than would a small country. Thus the monetary policy settings of a given currency union would to a larger extent reflect the economic dynamics of a given country the larger that country is relative to the size of the union overall. Previous authors have largely neglected this issue. We explicitly incorporate the size of each potential members' economy in our analytical framework and re-assess the merits of a range of regions forming a currency union. Using the framework developed, we also inquire into the optimality of current monetary regimes in two regions, the North American continent and in Australia. The first of these is motivated by Mundell's seminal article on currency unions where he asked in largely qualitative terms whether the US and Canada are better currency realms than a hypothetical north south divide of the continent. The second is motivated by the observation that Australia’s economy embodies (economically) very different sub-regions due to the difference importance of commodities production in different parts of the country. We ask whether these different regions experience symmetrical or largely idiosyncratic shocks and find support for the latter.
