Pengaruh Ekspor Netto dan Cadangan Devisa terhadap Jumlah Uang Beredar di Indonesia Tahun 1991-2009

This study aims at identifying and analyzing the influence of net exports and foreign exchange reserves on the money in motion (M2) in the period of 1991-2009 in Indonesia. The secondary data were collected from Indonesia Central Office of Statistic, Indonesia Monetary Statistic and Financial Reports of Bank of Indonesia. This research used the Ordinary Least Square (OLS) method for the analysis of the data. In the model, M2 was the dependent variable whereas the net exports and the foreign exchange reserves were the independent variable. The analysis states that M2 was influenced by the net exports and the reserves. The result show that the net exports and the foreign exchange reserves influenced on M2 significantly as indicated by R2 value of 0,06409. This means that 64,09 % increase of M2 was determined by the net exports and the foreign exchange reserves, and the rest of 35,91 % was determined by other factors. In the words, the exports and the reserves influenced on M2 simultaneously and significantly as shown by (M2) F –obtained > F –table (12.49855 > 3.59)

Anti-lecture Hall Compositions and Overpartitions

We show that the number of anti-lecture hall compositions of n with the first entry not exceeding k-2 equals the number of overpartitions of n with non-overlined parts not congruent to $0,\pm 1$ modulo k. This identity can be considered as a refined version of the anti-lecture hall theorem of Corteel and Savage. To prove this result, we find two Rogers-Ramanujan type identities for overpartition which are analogous to the Rogers-Ramanjan type identities due to Andrews. When k is odd, we give an alternative proof by using a generalized Rogers-Ramanujan identity due to Andrews, a bijection of Corteel and Savage and a refined version of a bijection also due to Corteel and Savage.Comment: 16 page

The Rogers-Ramanujan-Gordon Theorem for Overpartitions

Let $B_{k,i}(n)$ be the number of partitions of $n$ with certain difference condition and let $A_{k,i}(n)$ be the number of partitions of $n$ with certain congruence condition. The Rogers-Ramanujan-Gordon theorem states that $B_{k,i}(n)=A_{k,i}(n)$. Lovejoy obtained an overpartition analogue of the Rogers-Ramanujan-Gordon theorem for the cases $i=1$ and $i=k$. We find an overpartition analogue of the Rogers-Ramanujan-Gordon theorem in the general case. Let $D_{k,i}(n)$ be the number of overpartitions of $n$ satisfying certain difference condition and $C_{k,i}(n)$ be the number of overpartitions of $n$ whose non-overlined parts satisfy certain congruences condition. We show that $C_{k,i}(n)=D_{k,i}(n)$. By using a function introduced by Andrews, we obtain a recurrence relation which implies that the generating function of $D_{k,i}(n)$ equals the generating function of $C_{k,i}(n)$. We also find a generating function formula of $D_{k,i}(n)$ by using Gordon marking representations of overpartitions, which can be considered as an overpartition analogue of an identity of Andrews for ordinary partitions.Comment: 26 page

Retiring Workers Could Present a Problem for Marketers, Even in a Recession

Today\u27s workforce is aging fast. The tacit knowledge held by those approaching retirement is necessary for firms to compete in the increasingly competitive marketplace. While some research has been devoted to how older workers view their retirement will impact the workplace, minimal attention has been given to how younger workers view this issue. As companies strive to remain market-driven, this paper examines how younger personnel view the impact of retirement on their employers and the impending brain drain. A discussion of implications for the marketing function within firms also is provided
