Penetration and Post-infection Development of Meloidogyne Incognita on Tobacco as Treated by Rhizobacteria Pseudomonas Fluorescens Strain P-72-10

The bio-control potential of rhizospere bacteria Pseudomonas fluorescens against plant-parasite nematode had been demonstrated. P. fluorescens had shown the effect to enhance tobacco resistance to root-knot nematode Meloidogyne incognita. Inoculation with P. fluoreseens in tobacco could lead to significant reductions in the number of juveniles that penetrated tobacco root and further life stage development of the juveniles. The number of juveniles penetrated into tobac- co root in treatment with P. fluorescens is significantly different from CK at 2DAI, 6DAI, 8DAI and 10DAI. Significant reduction and delayed development of juveniles that penetrated into tobacco root and treated were observed in treatment at 14DAI, 21DAI, 28DAI and 35DAI. In addition, P. fluoreseens treatment leads to a significant reduction in the number of eggs per egg-mass at 35 DAI. The results show P. fluorescens induced a continuously suppression on root-knot nema- tode M. incognita throughout their entire early infection phase of root penetration, subsequent life stage development and reproduction.

Taxing Times in Indonesia: The Challenge of Restoring Competitiveness and the Search for Fiscal Space

Indonesia’s economic growth picked up slightly in mid-2016 but remains below the level demanded by government and popular aspirations. Despite a plethora of reforms intended to increase efficiency and productivity, some policies are perverse and longstanding problems of implementation remain. The share of manufacturing has declined, the real exchange rate has appreciated, exports have dwindled, and growth has been trending downwards. The banking sector is stable but inefficient, with wide net interest margins and numerous barriers to competition. Trade protection, particularly in basic food commodities, has created high costs that weigh particularly heavily on the poor. Declining government revenues have placed increasing pressure on the public budget, even as the current administration aims to increase spending on infrastructure and welfare and to enhance productivity. In an effort to increase revenues, the government has announced a tax amnesty program and other measures. In addition, Sri Mulyani Indrawati, the new finance minister, has taken steps to cut non-essential expenditure in order to secure high spending on infrastructure and at the same time keep within the 3% budget deficit limit stipulated by law. Although the overall debt situation is not yet alarming, declining revenues and budget cuts that do not fully reflect this decline are putting pressure on increasing debt levels. The government’s high-profile tax amnesty program was the major policy initiative implemented in the second half of 2016 that aimed to relieve this pressure. Despite widespread criticism of, and scepticism about, the tax amnesty (both within and outside Indonesia), its first phase had a much higher participation rate than most independent accounts expected. Revenues raised so far through the amnesty are less than 60% of the official target, but this is actually a strong result for the short term. The bigger question, however, is whether the amnesty is a key element of a more encompassing strategy to overhaul the system of taxation and tax administration.     

The causes of Japan's ‘lost decade’: The role of household consumption

In this paper, I analyze the causes of the prolonged slowdown of the Japanese economy in the 1990s and find that the stagnation of investment, especially private fixed investment, was the primary culprit. I then investigate the causes of the stagnation of household consumption during the 1990s and find that the stagnation of household disposable income, the decline in household wealth, and increased uncertainty about the future are among the contributing factors. Finally, I consider whether demand side factors or supply side factors were more important as causes of the prolonged slowdown of the Japanese economy in the 1990s and conclude that the former (especially misguided government policies) were probably more important.
