Cost-to-serve customers’ optimization: Macro project Unilever – Jerónimo Martins

The objective of this work project is to analyse and discuss the importance of the “Cost to Serve” as a differentiation key factor, by accessing cost to serve customers of a Portuguese subsidiary of a multinational company, which is operating in the sector of fast moving consumer goods (FMCG) – Unilever – Jerónimo Martins (UJM). I will also suggest and quantify key proposals to decrease costs and increase customers’ value. Hence, the scope of this work project is focused on logistics and distribution processes of the company supply chain.

Macro determinants of nonperforming loans in Portugal

This study uses a VAR methodology to evaluate the impact of the macroeconomic conditions and money supply in the fluctuation of nonperforming loans for the Portuguese economy. Additionally, the feedback effect of nonperforming loans growth to the economy and specially to the credit supply is analised. The study is motived by the hypothesis that loan quality is procyclical and that the fast growth of credit supply has a positive relation with the growth of nonperforming loans. The hypothesis that nonperforming loans reinforce economic fragilities and credit market frictions is also tested. Empirical results corroborate both hypothesis presented. Hence, it was possible to establish that the macroeconomic conditions measured by GDP and unemployment and the fast growth of credit supply contribute to the development of nonperforming loans. Furthermore, the growth of nonperforming loans reinforces the economic cycle, as it contributes to the deterioration of macroeconomic conditions and creates frictions in the credit market that may results in a credit crunch.

An analog model for global macro investing

This study proposes a systematic model that is able to fit the Global Macro Investing universe. The Analog Model tests the possibility of capturing the likelihood of an optimal investment allocation based on similarity across different periods in history. Instead of observing Macroeconomic data, the model uses financial markets’ variables to classify unknown short-term regimes. This methodology is particularly relevant considering that asset classes and investment strategies react differently to specific macro environment shifts.

An equity wealth preservation strategy: Following the macro trend

Financial crisis have happened in the past and will continue to do so in the future. In the most recent 2008 crisis, global equities (as measured by the MSCI ACWI index) lost a staggering 54.2% in USD, on the year. During those periods wealth preservation becomes at the top of most investor’s concerns. The purpose of this paper is to develop a strategy that protects the investment during bear markets and significant market corrections, generates capital appreciation, and that can support Millennium BCP’s Wealth Management Unit on their asset allocation procedures. This strategy extends the Dual Momentum approach introduced by Gary Antonacci (2014) in two ways. First, the investable set of securities in the equities space increases from two to four. Besides the US it will comprise the Japanese, European (excl. UK) and EM equity indices. Secondly, it adds a volatility filter as well as three indicators related to the business cycle and the state of the economy, which are relevant to decide on the strategy’s exposure to equities. Overall the results attest the resiliency of the strategy before, during and after historical financial crashes, as it drastically reduces the downside exposure and consistently outperforms the benchmark index by providing higher mean returns with lower variance.

Correlação entre macro e nanopartículas emitidas em fumos de soldadura MAG de aços inoxidáveis com diferentes gases de protecção

A soldadura é o processo mais utilizado na ligação de materiais. Os efeitos na saúde dos trabalhadores expostos a fumos de soldadura estão normalmente associados a danos pulmonares agudos e crónicos, mas também a outras condições médicas e doenças. O principal objectivo deste estudo foi correlacionar as emissões de macro e nanopartículas libertadas durante o processo de soldadura MIG/MAG de aços inoxidáveis com diferentes gases de protecção. Usando diferentes misturas gasosas utilizadas industrialmente com diferentes entregas térmicas, determinaram-se taxas de formação de fumos e áreas superficiais de nanopartículas com capaciade de deposição alveolar por volume pulmonar. Verificou-se como os diferentes modos de transferências e tipos de protecção gasosa, em particular, a percentagem de elementos activos na composição química do gás, afectam a quantidade de fumos gerados bem como a existência de nanopartículas com uma elevada capacidade de deposição alveolar. O modo de transferência por spray apresenta sempre valores superiores de área de superfície das partículas por volume pulmonar, ao contrário da taxa de formação de fumos. A mistura 82% Ar + 18% gera maiores emissões de nanopartículas bem como de fumos formados. A extracção na fonte e a regeneração do ar ambiente são a solução mais segura e eficiente de controlo das emissões de macro e nanopartículas em soldadura.

The transformation of work? A quantitative evaluation of changes in work in Portugal

This report is made for the Work Package 15 of WORKS project and tries to develop more information on the Portuguese situation in the work structures changes in the recent years. It starts with an analysis of socio- economical indicators (Macro economical indicators, Employment indicators, Consumption, Technology at the workplace, Productivity), and then approaches the situation in terms of work flexibility in its dimensions of time use and New forms of work organisation. It traces employment in business functions with a sectoral and occupational approach, and analyses the occupational change in South Europe with particular relevance to Portugal (skill utilisation and job satisfaction, occupational and industrial mobility, quantitative evaluation of the shape of employment in Europe. Finaly are analysed the globalisation indicators.
